# 1.0 Narrative Task Description {#narrative-task-description .unnumbered}

## 1.1 Background/Problem Description

Within human spaceflight, there are two different phases that define
suit functionality. One phase includes launch, entry, abort, and
survivability (LEAS). Survivability is associated with pre-launch,
launch, entry and post-landing survival. This first phase includes
suit-up, transfer to pad, vehicle ingress, launch through
post-insertion, rendezvous/docking, entry and post-landing. This phase
contains contingency plans for launch aborts, both on the pad or
in-flight, including survival in an unpressurized cabin or an emergency
vehicle egress.

The second phase of spaceflight includes performing extravehicular
activity (EVA), both in microgravity and in the partial gravity of a
planetary surface. For example, during a planetary mission, performing
an EVA in microgravity may take place in Low Earth Orbit (LEO), Low
planetary orbit, or during planetary transit. A partial gravity surface
EVA would be performed as part of planetary exploration, outpost
buildup, or for basic science.

In the Shuttle/International Space Station (ISS) Program, the National
Aeronautics and Space Administration (NASA) has implemented a two-suit
system to satisfy both spaceflight phases as described above. The
Advanced Crew Escape Suit (ACES) is used for launch, entry, abort,
(LEA); the Extravehicular Mobility Unit (EMU) is used for EVA. The ACES
provides all LEA functionality including pre-launch and post-landing
survival. However, the ACES does not support EVA or long duration
protection in an unpressurized cabin.

The Shuttle EMU is used to provide a 4.3 psi pressurized environment for
microgravity EVAs only. The large mass and lack of mobility in a gravity
environment would not allow it to satisfy LEAS functions or planetary
EVA functions.

To minimize mass and volume impacts, one of NASA's goals is to evaluate
space suit systems that combine the functionality of LEAS with the
capabilities required for contingency zero gravity EVA and planetary
surface EVAs for planetary missions. The basis for this statement of
work is the desire for a common helmet which optimizes both LEAS and EVA
functionality, while minimizing helmet mass and volume impacts.

# Helmet Attributes

For the benefit of the contractor, sections 1.2.1 and 1.2.2 below list
important considerations/attributes of the helmet for LEAS and EVA
respectively. Note: These are not considered requirements (e.g., shall
statements) as required by this DO, but rather, information provided by
NASA to the contractor to emphasize the important helmet attributes
relative to the two (2) distinctly different flight phases. Distinct
requirements will be identified per subsequent sections of this DO
accordingly and will be identified with "shall" statements.

## Helmet Attributes for LEAS

### In support of LEAS capability, the helmet in combination with the suit should provide crewmembers with the following functional attributes. Ultimately, in the future, the suit/helmet combination will have to address the following attributes, however, for the purposes of this DO, the following information is provided as background information only to assist the contractor in completing the DO.. 

-   1 g mobility for pre-launch and post-landing emergency egress. In
    this scenario the helmet's mass, mobility, and crew interface become
    critical.

-   Long duration seated comfort prior to launch. The helmet may be worn
    for long durations (e.g., up to \~3-4 hours) and consequently must
    be comfortable and/or preclude excessive heat loads for extended
    durations pre-launch. Note: 1\] No active cooling is expected to be
    included in the helmet, 2\] The helmet is not expected to
    accommodate a head borne portion of a liquid cooling garment, 3\]
    Any cooling provided in the helmet during pre-launch activities
    should be a function of the natural flow of cabin ventilation (if
    the helmet is open) or simply as a characteristic of the normal
    ventilation of breathing gas through the helmet cavity (helmet open
    or closed).

-   Protection from accelerations. This includes protection from head
    accelerations and/or impact and neck injury during dynamic phases of
    flight, including landing.

-   Pre-launch, post-landing smoke/fire/toxic air protection. The helmet
    should provide smoke/fire/toxic air protection to the crewmembers
    throughout all mission phases.

-   Post-landing protection during water egress. This includes
    preventing water from entering the suit during a post landing egress
    of the vehicle following a water landing.

-   "Openable" visor to allow access to the crewmember's face and to
    allow for open suit operations to breathe ambient cabin air when not
    integrated into the vehicle Environmental Control and Life Support
    System (ECLSS).

-   Integration of a Valsalva device to assist with inner ear pressure
    equalization during pressurization of the helmet and suit.

-   A field of view (FOV) sufficient to view vehicle displays and to
    operate controls to perform necessary seated operations. For two
    crew operations, this includes the capability to view and confirm
    second crewmember's inputs for mission critical functions.

-   Integrated anti-suffocation prevention capability. Anti-suffocation
    provides a secondary method of introduction of ambient air to the
    helmet for crewmember inhalation in the event a crewmember becomes
    unconscious and the primary breathing gas supply has been exhausted
    or is no longer available.

-   Long duration survival for return in a non-pressurized vehicle (\~
    up to 120 hours). Examples include provisions for introduction of
    water, nutrition, and medicine into the helmet for consumption by
    the crew during extended pressurized helmet/suit operations.

-   Rapid don/doff capability in the event of a sudden loss of cabin
    pressure occur or if contaminants are introduced within the cabin.
    The helmet should have rapid doffing capability. That is required
    should a crewmember need access to breathable air and need to reduce
    thermal loading upon a post-landing rapid vehicle egress.

-   Anti-fog prevention to keep the humidity emitted from a crewmember's
    breath and within the suit from collecting on the internal surface
    of the helmet thereby limiting visibility.

-   Integrated noise protection to limit the crewmembers' ambient noise
    exposures over the frequencies and sound levels that occur during
    all phases of ascent and entry.

-   Capability to integrate the crew Communications, Avionics and
    Informatics (CAI) System.

## Helmet Attributes for EVA

### In support of EVAs, which include microgravity and partial gravity surface EVAs, the helmet should provide crewmembers with the following functional attributes. Ultimately, in the future, the suit/helmet combination will have to address the following attributes, however, for the purposes of this DO, the following information is provided as background information only to assist the contractor in completing the DO. 

-   Thermal, UV/IR/Solar radiation protection.

-   Anti-glare prevention to preclude glare from obscuring vision. For
    example, sun shades were needed to reduce glare when facing
    low-sun-angle conditions during Apollo lunar surface EVAs.

-   Surface EVA FOV that allows for an extended downward viewing such
    that the crewmember can see his/her feet for walking on the
    planetary surface or down a vehicle ladder with distortion-free
    visibility. This includes a FOV to mate/de-mate a suit umbilical and
    view suit controls. The contractor should declare assumptions for
    umbilical locations.

-   Microgravity EVA FOV to allow a crewmember to perform EVA-related
    tasks that include maneuvering to the intended worksite and tool
    manipulation and use.

-   Micrometeoroid and orbital debris (MMOD) protection.

-   Prevention of inadvertent opening of the helmet. A visor which can
    be easily opened for nominal intravehicular activity (IVA) should
    have locks/inhibits to preclude inadvertent opening which could
    result in loss of crew.

-   Tolerance to planetary dust/regolith. This should include, but not
    be limited to, preventing planetary dust from damaging or impacting
    the performance of helmet components, degradation of seals, jamming
    slide mechanisms, compromising any locking mechanisms, or
    degradation of the optical quality of visor surfaces.

-   Capability to interface with the suit-provided ventilation system.
    An example would include provision for appropriate suit-provided
    directional gas flow into the helmet for ventilation and carbon
    dioxide (CO~2~) control.

-   Capability to integrate the crew Communications, Avionics and
    Informatics (CAI) System.

# 2.0 Purpose of the Delivery Order {#purpose-of-the-delivery-order .unnumbered}

The contractor will develop/evaluate design concepts and conduct trade
studies in accordance with (IAW) Section 3.0, Task Description, for a
common helmet which combines and optimizes both LEAS and EVA
performance, trading mass and volume impacts.

#  {#section-2 .unnumbered}

# 3.0 Task Description {#task-description .unnumbered}

The contractor shall develop and evaluate concepts for a [Common Hemet
System]{.underline} which interfaces with both of the two (2) space suit
configurations described below. The task is divided into two (2)
sub-tasks (Task #1 and Task #2) described per section 3.1 and 3.2. For
the purposes of this effort, the helmet is defined as the components
interfacing with each of the respective configurations described below.

Definition: For the purposes of this DO, [Common Helmet
System]{.underline} is defined as any and all components/hardware that
comprises the entire helmet system which interfaces with both suit
configurations as defined below. Note that C[ommon Helmet
System]{.underline} may consist of a single helmet, multiple helmets, or
a combination of interchangeable components, with the objective of
minimizing overall mass and volume, while optimizing performance.

**Space Suit/Helmet Interface Configuration Descriptions:**

> There are two (2) specific space suit configurations in which the
> common helmet concepts must operate with as a system. These two suit
> configurations share many common components. Both configurations will
> share the same soft Lower Torso Assembly (LTA), lower arms, gloves,
> helmet, and boots, however, have separate Soft Upper Torso (SUT)
> assemblies, which support different functions as described below per
> each configuration. The common helmet system concept(s) developed per
> this DO must interface with the two (2) separate SUTs.
>
> *Note: For clarification, the suit configurations as described
> (Configuration 1 and 2), do not physically exist, but rather are
> notionally described below to provide the contractor with relevant
> details of each of the two (2) suits configurations for which the
> common helmet concepts must be integrated. Since helmet design is
> highly dependent on suit configuration, details of the configurations
> are provided such that the contractor has relevant notional suit
> details from which to base helmet design/concept decisions. Specifics
> of physical interfaces as required by NASA for the purposes of this DO
> (e.g., the I-Suit and the Mark III) are also described below.*

-   Configuration 1 suit is a LEAS/contingency EVA configuration. The
    LEAS/contingency configuration's upper torso is optimized for
    unpressurized mobility during 1 g and 0 g EVAs. This upper torso has
    a waist entry body seal closure (BSC). It is primarily a SUT with
    limited upper body mobility elements, including low profile scye
    bearings, upper arm bearings and a neck ring. It is also optimized
    for low volume and weight.

> [Note: For this DO, the contractor shall assume that the configuration
> 1 helmet interface is the EMU/Apollo neck ring as installed on the
> current I-Suit. See Figure 3-1. Additional details of the I-Suit are
> included in the NASA CRAVE Technical Library.]{.underline}

### 

-   Configuration 2 suit is the Surface EVA configuration. The Surface
    EVA upper torso is optimized for pressurized surface EVA mobility
    and able to support the Portable Life Support System (PLSS) mass and
    interfaces. The configuration 2 upper torso is a soft rear entry SUT
    with a rear entry hatch. This SUT will also have a waist bearing and
    a BSC. Scye bearings are angled for optimal shoulder/arm mobility.
    There will be disconnects for upper arms and gloves.

## 3.1 Task #1 Requirements - Common Helmet System Concept Development

For this task, the contractor shall generate and evaluate common helmet
system concepts(s) that support both suit configurations (as defined in
Section 3.0) while minimizing the common helmet system mass and volume.
In completion of this task, the contractor shall perform the following:

3.1.1 The contractor shall brainstorm and develop common helmet system
concepts. An example of such a design process can be found in the book
titled "The Mechanical Design Process," by David Ullman and may be used
as reference.

> 3.1.1.1 The contractor shall develop and evaluate concepts that
> interface with the two (2) suit configurations (Configuration 1 and
> Configuration 2) as defined per Section 3.0.
>
> 3.1.1.2 The contractor shall develop and evaluate concepts against,
> but not limited to, the [Focal Points]{.underline} (items
> \[A\]-\[AA\]) listed in Section 4.0.
>
> 3.1.1.3 The contractor shall develop and evaluate concepts considering
> the list of Helmet Environments provided in Section 5.0.

3.1.2 The contractor shall conduct a feasibility assessment, evaluate
and rank the concept(s), and provide NASA with the recommended
concept(s). Those concepts eliminated early in the process shall be
provided with rationale for elimination.

3.1.3 The contractor shall evaluate the technology risks and/or
anticipated issues associated with the design development, test, and
evaluation of concept(s), including mass/volume properties of the
respective concepts.

3.1.4 The contractor shall provide design concepts and analyses to NASA
in the form of a final report and presentation.

## 3.2 Task #2 Requirements - Alternate Common Helmet

As an extension to Task #1 described above in section 3.1, the
contractor shall explore, generate, and evaluate alternate common helmet
concept(s). Such concepts shall maintain the general theme of the
NASA-provided two (2) suit configuration systems for an LEAS/contingency
EVA configuration and the Surface EVA configuration (as described in
Section 3.0) however, the contractor may explore alternate integration
or interface options other than those defined per Section 3.0 (i.e.,
Shuttle/Apollo EMU neck ring shown on the I-Suit for LEAS/contingency
EVA configuration and/or Mark III Ortman coupler for surface EVA
configuration). An example of such a concept includes, but is not
limited to, integrated soft helmet(s) (e.g., Russian Sokol helmet) for
either configuration in lieu of the Shuttle/Apollo EMU neck ring and/or
Ortman coupler. This task is requested by the contractor as an extension
of Task #1 to reduce the interface restrictions provided per Task #1 to
promote creative thinking/solutions with respect to helmet concepts and
helmet integration. In completion of this task, the contractor shall
perform the following:

3.2.1 The contractor shall brainstorm and develop alternate common
helmet system concepts. An example of such a design process can be found
in the book titled "The Mechanical Design Process," by David Ullman and
may be used as reference.

> 3.2.1.1 The contractor shall develop and evaluate concepts that
> interface with the two (2) suit configurations (Configuration 1 and
> Configuration 2) as defined per Section 3.0, with the exception of the
> I-suit and Mark III Interfaces (i.e., contractor may deviate from the
> I-Suit neckring and EMU Ortman coupler where appropriate provided the
> contractor maintains the waist entry SUT for the LEAS/contingency EVA
> configuration and rear entry SUT for the Surface EVA configuration.
>
> 3.2.1.2 The contractor shall develop and evaluate concepts against,
> but not limited to, the [Focal Points]{.underline} (items
> \[A\]-\[AA\]) listed in Section 4.0.
>
> 3.2.1.3 The contractor shall develop and evaluate concepts considering
> the list of Helmet Environments provided in 5.0.

3.2.2 The contractor shall conduct a feasibility assessment, evaluate
and rank the concept(s), and provide NASA with the recommended
concept(s). Those concepts eliminated early in the process shall be
provided with rationale for elimination.

3.2.3 The contractor shall evaluate the technology risks and/or
anticipated issues associated with the design development, test, and
evaluation of concept(s), including mass/volume properties of the
respective concepts.

3.2.4 The contractor shall provide design concepts and analyses to NASA
in the form of a final report and presentation.

### 3.3 Option 1

After reviewing the completed base DO final report and participating in
the contractor final presentation, NASA may elect to enact Option 1,
which shall include design and fabrication of one or more prototype
helmets (see Attachment 1). NASA reserves the right to make changes to
the helmet concept selected and Option 1 requirements prior to enactment
of Option 1.

**4.0 Concept Development Focal Points**

The focal points of the design concept(s) shall include but not be
limited to the items listed below. Section 3.1 and 3.2 of this DO
requires the consideration of all 4.0 Section focal points. Evaluation
of each focal point shall be described in detail in the final report. If
the concepts fail to adequately address any of the focal points, the
contractor shall provide information demonstrating why the concept
failed to address the focal point. The contractor shall also provide a
description of the effort that would be required to satisfy the focal
point. Focal points are divided into two (2) separate sections
consisting of [LEAS/contingency EVA]{.underline} focal points first and
[Surface EVA]{.underline} focal points second.

**4.1 Focal Points of the Helmet for LEAS/contingency EVA:**

The following describe the important focal points associated with the
Helmet for LEAS/contingency EVA.

A.  Head and neck protection study

-   Neck protection from accelerations during all dynamic phases of
    flight

```{=html}
<!-- -->
```
-   The Neck Injury Criteria (Nij) developed by the Federal Motor
    Vehicle Safety Standards (FMVSS 208) and the National Highway
    Traffic Safety Administration (NHTSA) should be used as a guide.

```{=html}
<!-- -->
```
-   Head impact and protection for launch/landing accelerations

```{=html}
<!-- -->
```
-   Concepts should consider, but not be limited to ANSI Z90.1 as a
    guide.

```{=html}
<!-- -->
```
-   External object impact and penetration protection

```{=html}
<!-- -->
```
-   Concepts should consider, but not be limited to ANSI Z90.1 as a
    guide.

> B. Conformal versus Non-Conformal -- Includes a trade study of
> conformal versus non-conformal helmet concepts.
>
> C. Head-borne Mass -- Minimize head-borne mass. To minimize head-borne
> mass is to minimize stress on the head and neck during all flight
> phases. If helmet weight/mass or a portion thereof must be supported
> directly by the crewmember's head/neck, the goal will be less than 4.0
> lb directly supported by the neck/head.
>
> D. Suit-Provided Ventilation Integration -- Evaluate suit-provided
> ventilation integration, including helmet internal flow direction for
> CO~2~ control, head cooling, and visor fogging prevention. *Note: The
> contractor should assume ventilation is suit-provided within the
> suit/helmet interface and is NOT directly supplied to the helmet via
> external helmet connections.*
>
> E. Nutrition, Hydration, and Medicines -- Evaluate methods for
> delivery of nutrition, hydration, and medicines while in the
> pressurized helmet. This is required for contingency long duration
> survival during return in a non-pressurized vehicle (\~120 hours).
>
> F. Stowage Volume -- Minimize stowage volume including stowage
> configuration and provisions (e.g., bags, boxes, spacers, protective
> covers, etc.). The maximum stowage volume goal for the helmet
> [system]{.underline} should be less than 2,200 cubic inches (in^3^),
> which is equivalent to the EMU helmet stowage volume.
>
> G. Comfort -- Develop a concept for long duration comfort. The helmet
> may be worn for long durations (e.g., up to \~3-4 hours) in 1 g
> pre-launch configuration and consequently must be comfortable and/or
> preclude excessive heat loads for those extended durations. Another
> consideration should be made for wearing the helmet in 0 g for a long
> duration contingency of \~120 hours in a lunar return within an
> unpressurized vehicle.
>
> H. Anti-suffocation methods. Anti-suffocation provides a secondary
> method of introduction of ambient air to the helmet for crewmember
> inhalation in the event a crewmember becomes unconscious and the
> primary breathing gas supply has been exhausted or is no longer
> available. Vomitus isolation/management/containment is also included
> in this category.
>
> I. CAI -- Provide concepts for a Communications, Avionics and
> Informatics (CAI) system, which will include, but not be limited to,
> the following:

-   [Communication]{.underline}: Evaluate integration of communications
    systems options including, but not limited to, communications cap
    and/or integrated helmet-mounted microphone and speakers. Note: For
    this task, NASA desires the contractor to evaluate the integration
    of various types of technically mature communications systems as
    appropriate; however, the focus of this task is NOT on the design
    details and/or particulars of the communication system itself.

-   [Hearing Protection]{.underline}: Provide hearing protection
    integration (e.g., head-mounted noise attenuation and/or inherent
    helmet noise attenuation). Note: For this task, NASA desires the
    contractor to evaluate the conceptual integration of various types
    of technically mature hearing protection systems as appropriate;
    however, NASA does NOT desire that the contractor spend effort on
    the design details and/or particulars of the hearing protection
    system itself.

-   [Noise Avoidance and/or Mitigation]{.underline}: Minimize noise from
    ventilation flow over the microphone (e.g., helmet-mounted or
    head-mounted type.)

-   [Heads-up Display]{.underline}: Develop a concept for accommodating
    a potential heads-up display or projection hardware for EVA. For
    this task, NASA desires the contractor to evaluate the conceptual
    integration of various types of technically mature heads-up display
    systems as appropriate; however, NASA does NOT desire that the
    contractor spend effort on the design details and/or particulars of
    the heads-up display system itself.

-   [Camera/Video/Lighting Integration]{.underline}: Evaluate
    integration of camera and lighting systems. For this task, NASA
    desires the contractor to evaluate the conceptual integration of
    various types of technically mature camera/video/lighting equipment
    as appropriate; however, NASA does NOT desire that the contractor
    spend effort on the design details and/or particulars of the
    camera/video/lighting equipment itself.

> J. Visor -- Provide concepts for a visor, which will include, but not
> be limited to, the following:

-   Implementing an "openable" visor for LEAS.

-   Precluding inadvertent opening of the visor for EVA phases and
    on-orbit mission phases. A visor which can be easily opened for
    nominal IVA should have locks/inhibits to preclude inadvertent
    opening which could result in loss of crew.

-   Contingency EVA UV/IR/Thermal protection. This includes limits
    placed on the ultraviolet transmittance through the visual area of
    the Helmet/Visor Assembly to prevent any corneal damage for the
    total time of UV exposure in a mission. The visible light
    transmittance will provide adequate visibility to permit performance
    of tasks in high glare areas in direct sunlight without discomfort.
    The infrared transmittance shall be a level which will prevent any
    possible retinal burn damage. The transmittance of the visual area
    of the visor will conform to the limits below:

> **Table 4-1: Limits on Transmittance**

  ----------------------- -----------------------------------------------

  portion of spectrum     

  IR portion of spectrum  Range of Nanometers: 700+
  to be blocked           
  ----------------------- -----------------------------------------------

> K. Ventilation Initiation System -- Develop a concept for a
> ventilation initiation system (e.g., automatic activation of
> ventilation flow when visor is closed, or manual initiation of
> ventilation flow).
>
> L. Environments -- Compatibility with relevant environments which
> include 100 percent oxygen (O~2~), 0-100 percent relative humidity,
> cold water relative to cold water landings, and other identifiable
> environments for contingency EVA (i.e., LEO, LLO, and trans lunar).
> Compatibility with EVA environments will include exposure to UV, IR,
> hot and cold thermal extremes, and radiation. Details concerning these
> environments are included in this document.
>
> M. Material Selection Trade -- If using new or exotic material, or
> known material in a different application, the contractor shall
> evaluate flammability, fracture control, life cycles, reliability,
> dust interactions, environmental issues, etc.
>
> N. Critical Area of Vision -- For microgravity EVA, helmet concepts
> should be evaluated for a critical area of vision that meets or
> exceeds the following visual ranges:

P.  Operating Pressure -- Concepts should be developed/evaluated for the
    following internal pressure environments:

-   A maximum operating pressure of 8.0 pounds per square inch
    differential (psid)

-   Proof pressure of 12.0 psid, which is 1.5 times the maximum
    operating pressure of 8.0 psid.

-   Ultimate pressure of 16.0 psid, which is 2.0 times the maximum
    operating pressure of 8.0 psid.

Q.  Operational Environment for Seated Helmet - The environment around
    the helmet exterior must provide enough volume to allow helmet
    operations by the seated crewmember (LEAS/contingency EVA
    configuration) within the confines of a space vehicle. Helmet
    concepts should be operable as worn within an 18-inch (in) diameter
    spherical volume centered 9 in above the seatback surface at the
    seated occupant's head center of mass location to allow for helmet,
    helmet operations clearance, and occupant protection.

**4.2 Focal Points of the Helmet for Surface EVA:**

The following describe the important focal points associated with the
Helmet for surface EVA.

R.  Thermal, Micrometeoroid, Dust (TMD) protection -- Includes concepts
    for TMD protection for the helmet. Concepts include, but are not
    limited to, removable and/or integrated TMD protection.

S.  Planetary Dust Tolerant -- Concepts for tolerance to planetary dust
    should include, but not be limited to, preventing planetary dust
    from damaging or impacting the performance of helmet components,
    degradation of seals, jamming slide mechanisms, compromising any
    locking mechanisms, or degradation of the optical quality of visor
    surfaces.

T.  UV/IR/Thermal Protection -- Concepts for UV/IR/Thermal protection
    for the planetary surface environment should provide limits on the
    ultraviolet transmittance through the visual area of the helmet in
    order to provide adequate protection to prevent any corneal damage
    for the total time of EVA exposure in a mission. The luminous
    transmittance will provide adequate visibility to permit performance
    of tasks in high glare areas in direct sunlight without discomfort.
    The infrared transmittance shall be a level which will prevent any
    possible retinal burn damage. The transmittance of the visual area
    of the visor will conform to the limits below:

5.0 Helmet Environments

The following paragraphs provide relevant helmet environment
information. Sections 3.1 and 3.2 of this DO requires the consideration
of all Section 5.0 environments in completion of this DO.

### 5.1 Internal Helmet Environment: Thermal/Humidity/Gas Flow Rate

The ventilation gas entering the helmet environment nominally will be
maintained within the limits of 65ºF to 80ºF with a dew point of
approximately 50ºF where it enters the helmet. The dew point below the
oral/nasal area of the helmet increases, due to the crewmember's breath,
in the range of 60ºF to 80ºF.

Suit-provided flow rates into the helmet should include, but not be
limited to, the range of 4.5 to 6.0 ACFM of oxygen or breathing air.

### 5.2 EVA External Thermal Environment

For the purposes of this DO, the current worst case hot and cold
environments have been determined by thermal analysis at NASA -- JSC.
These hot and cold environment extremes are bounded by the lunar surface
environmental thermal analysis results. The lunar surface thermal
extremes have been found to exceed what will be expected for
microgravity EVAs in LEO, lunar transit or LLO, therefore they will be
used to bound the thermal maximum and minimum range.

1.  Hot Case -- The lunar surface thermal environment assumes a
    crewmember's placement on the lunar surface inside a 4:1 aspect
    ratio crater with the sun located at a 0° zenith angle, directly
    overhead. With the crewmember looking down, the incident solar flux
    is calculated at 31 Btu/hr/ft^2^ and the incident IR flux is 509
    Btu/hr/ft^2^. Materials that can operate safely within this
    environment should be carefully selected. As an example, the outer
    sun visor temperature of the current Shuttle EMU helmet in this
    environment, can achieve +279^o^F.

2.  Cold Case -- In a lunar night case there is no difference between
    standing within a crater versus standing on a flat plane. During
    lunar night the incident solar flux is 0 Btu/hr/ft^2^ and the
    incident IR flux is 2 Btu/hr/ft^2^. Design concerns for this cold
    case are that the lower limit temperatures can result in material
    embrittlement. As an example, during lunar night, the current
    Shuttle EMU helmet outer sun visor temperature can reach -283^o^F
    while the middle protective visor can reach -139^o^F.

### 5.3 Metabolic Rates

Metabolic rates can affect the internal surface conditions of the helmet
so as to produce fogging from the increase in humidity and/or thermal
conditions. Examples of two metabolic profiles are shown in the figures
below.

# 10.0 Government Furnished Property  {#government-furnished-property .unnumbered}

The CRAVE contracts do not anticipate the Government providing any
property or test facilities unless requested by the contractor in their
response to a request for bid.

Attachment 1 -- Option 1

The Government may exercise the option described below for the option
value listed on the DO cover page by written notification to the
contractor from 90 days after the completion of the base contract.

**[OPTION 1 TITLE]{.underline}: Prototype Helmet Fabrication**

# 1. 0 Purpose of the Current Effort {#purpose-of-the-current-effort .unnumbered}

After receiving approval to proceed to Option 1 of the task, the
contractor will use the concept(s) from this DO along with any
new/changed NASA-provided requirements/concepts, to design and fabricate
a prototype helmet(s). The helmet will be designed to function in
ambient pressurized conditions. This may include flights on a 0 g
aircraft or evaluations in a laboratory environment. It is not
anticipated to be used in a vacuum, thermal environment, or neutral
buoyancy lab (NBL). The contractor shall be responsible for testing all
helmets to ensure that requirements have been met. The contractor shall
deliver all hardware with the final report to detail all findings to
NASA JSC upon completion of this DO option.

# 2.0 Task Description {#task-description-1 .unnumbered}

## 2.1 Project Schedule

The contractor shall develop a schedule detailing the plan for prototype
design, analysis, and manufacturing with anticipated milestone dates
within the given project period.

## 2.2 Design and Fabricate Prototype Helmet

The contractor shall design, fabricate, assemble, test, and deliver the
helmet(s) for integrated suit testing. The focal points of the helmet
design and fabrication shall include the results of the various concept
studies as directed by NASA, the helmet prototype requirements supplied
with Option 1, Section 3.0 below, and the requirement changes and design
decisions made by NASA at the end of the base contract.

**3.0 Prototype Helmet Requirements**

The following lists the specific requirements of the prototype helmet(s)
hardware items that are to be delivered by the contractor per this
Option 1 Task.

1.  Maximum Operating Pressure -- The maximum operating pressure shall
    be 6.0 psid. The helmet shall be pressurized at ambient conditions.
    *Note: MOP has been reduced to 6.0 for the prototype in Option 1 as
    compared to 8.0 psid per the Base DO (see item P) to relax the
    pressure requirement on the prototype hardware and to synchronize
    the prototype hardware with the maximum pressure utilized in
    standard ground level testing.*

2.  Proof Pressure -- Proof pressure shall be 9.0 psid, which is 1.5
    times the maximum operating pressure of 6.0 psid. There shall be no
    structural damage resulting from this pressure. *Note: MOP has been
    reduced to 6.0 for the prototype in Option 1 as compared to 8.0 psid
    per the Base DO (see section P) to relax the pressure requirement on
    the prototype hardware and to synchronize the prototype hardware
    with the maximum pressure utilized in standard ground level
    testing.*

3.  Ultimate Pressure -- Ultimate pressure shall be 12.0 psid, which is
    2.0 times the maximum operating pressure of 6.0 psid. No
    catastrophic failure shall result from this pressure. *Note: MOP has
    been reduced to 6.0 for the prototype in Option 1 as compared to 8.0
    psid per the Base DO (see section P) to relax the pressure
    requirement on the prototype hardware and to synchronize the
    prototype hardware with the maximum pressure utilized in standard
    ground level testing.*

4.  Helmet Leakage Rate -- The maximum leakage rate for the helmet when
    operating in a 1-g atmospheric environment of air at 6.0 psid shall
    be 200 scc/m. Note: this requirement is to ensure safe operation of
    the prototype helmet in test operations. No analogous requirement is
    described in the Base DO, because leakage rates are assumed to be a
    function of each of the the design concept and therefore, no
    specific focal point was described in the Base DO.

5.  Interface with Pressure Garment -- The helmet shall interface with
    the pressure garment. The prototype helmet shall interface with the
    Shuttle/Apollo EMU neck ring on the I-Suit and the MARK III Ortman
    coupler. (Refer to Base DO Interface requirements per Section 3.0)

6.  Ventilation Flow -- The helmet shall allow for ventilation flow to
    provide visor defogging, head cooling, and CO~2~ removal across the
    oral-nasal area. For the purposes of this prototype, air will be
    used. See section D in the Base DO).

7.  Anthropometry -- The prototype helmet(s) shall fit the crewmember
    head size ranges listed below.

    Head breadth range: 5.2 -- 6.5 in

    Head length range: 6.8 -- 8.5 in

    Menton to top of head range: 8.0 -- 9.7 in

height="2.2in"}

> **Figure 3-1: Anthropometric Head Size Ranges**

8.  Critical Area of Vision -- The helmet shall provide a critical area
    of vision that meets or exceeds the following visual ranges (see
    items N and U from the Base DO):
