These small wireless facilities are placed with the intent to fill in areas that do not have sufficient capacity. Increased capacity will help improve voice quality, reliability and data speeds for San Bruno residents, businesses, first responders and visitors using the wireless networks.A typical small cell within the right-of-way is 50 feet or less in height, consists of one or more antennas and one or more equipment boxes. The antennas will be mounted either at the top of the pole or on the side. The equipment boxes will be attached to the pole, installed on the ground, or in the case of new streetlight installations, potentially in the base of the pole itself. While every system varies, the equipment boxes typically include a disconnect switch, and computers to control the antennas. Some wireless facilities may also feature an equipment box, on the same pole or in a box near the pole, that contains batteries used to provide temporary emergency power to the facility in case of a power outage. 

2.
What is Public Right of Way?

Public right-of-way refers to a strip of land, which is used as a roadbed, either for a street, railway or other accessway. The land is set aside as an easement or in fee, either by agreement or condemnation. The public right of way generally consists of the roadway, sidewalks and a strip of land behind the sidewalk (which varies by neighborhood). 

3.
What is the range of these systems?

A number of factors dictate the range of small cells, including objects that can potentially block the signals such as trees or buildings. On average, these systems have an approximate range of 150 to 500 feet due to their low mounting height and low power output (either 66, 100, or 174 watts). For comparison purposes, a typical "macro" facility, with higher power usage (e.g. 10,000+ watts), and a higher mounting location, can have a range of a mile or two. 

4.
Can the City prohibit the installation of wireless telecommunication facilities?

No. Under State and Federal law, telecommunications carriers have a right to install wireless facilities in the public right-of-way.
ASTER | Terra
Efforts to contain the fire continue with 21 hand crews, 10 helicopters and dozens of fire engines deployed to the area. Smoke impacts to surrounding communities are being carefully monitored.
With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet (15 to 91 meters), ASTER images Earth to map and monitor the changing surface of our planet. It is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan’s Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.
The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.
The U.S. science team is located at NASA’s Jet Propulsion Laboratory in Southern California. The Terra mission is part of NASA’s Science Mission Directorate, Washington.

ASTER Views Kilauea

Posted on May 8, 2018 by Tassia Owen 
	Posted in News and Events 

When volcanoes erupt, ASTER turns its attention to documenting the changes to the landscape as they happen. ASTER is uniquely capable of turning to see areas where volcanoes are erupting in very high resolution (between 15 in the thermal bands – 90 meter spatial resolution in the visible light spectral bands).
As Hawaii’s Kilauea continues to erupt, ASTER continues to monitor the eruption from space.

HEASARC Help Desk, Feedback, and Frequently Asked Questions (FAQ)
HESS arrays of
atmospheric Cerenkov telescopes, nor from balloon or sounding rocket payloads
(with a few exceptions, e.g., the soft X-ray data from 10 University of 
Wisconsin sounding rockets flown in the 1970s are archived here).
Neither does the HEASARC have any cosmic ray datasets: such data are archived
at a variety of other sites, including 
NSSDC and 
SPIDR,
and mission archives such as the 
ACE Science Center and the 
SAMPEX Data Center

What format are HEASARC data files in?

The majority of HEASARC data are stored in 
FITS
format. FITS is the data format most commonly used within astronomy. The
fv package provides a simple way
to view FITS files.

How do I download X-ray or gamma-ray data from the HEASARC?

The HEASARC's main archive page 
has 9 interfaces with various purposes and degrees of sophistication.
These are designed to help you identify datasets of interest
based on various astronomical and mission-based criteria and then to allow you 
to download these data. If you are already familiar with the structure 
of our archive, you can also get direct access to the data directories through 
http.

How do I get started in X-ray or gamma-ray data analysis?

The HEASARC's XANADU package
supports spectral, temporal and spatial analysis of high-energy data and
has been developed to be quite portable. You can use this immediately on
the high-level products in the HEASARC archive. The FTOOLS provide more
discrete analysis tools including mission-specific analysis pipelines.
These two packages along with some other useful software have been
consolidated into the HEAsoft package.

How do I acknowledge data obtained from the HEASARC?

If using the HEASARC service made a significant contribution to a research
project, please make the following acknowledgement in any resulting
publication:

Bad (space) weather cancels pigeon races! | NASA Space Place – NASA Science for Kids
The next generation of geostationary satellites, called GOES-R, will have even better instruments to keep an eye on the Sun. That’s important not only for pigeon racers, but for people in charge of keeping satellites, power grids, and astronauts safe. The blasts of charged solar particles can cause a lot of damage to these technologies, and cause injury to humans in space.

This instrument on the new GOES-R satellite is called the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS. It will monitor solar flares that can cause problems with power grids, communication satellites, and pigeon races.
 
This instrument on the new GOES-R satellite is called the Solar Ultraviolet Imager, or SUVI. It will monitor the Sun and give us early warning of bad space weather coming our way.
How We Find and Characterize - NASA Science
It includes self-flexing mirrors, with thousands of tiny, piston-like actuators that flex in real time as the telescope captures light that has traveled tens of light years from an exoplanet. These "deformable mirrors" compensate for subtle flaws in telescope optics to squelch starlight and make the planet's light clearer.When NASA's Nancy Grace Roman Space Telescope opens its eyes in the mid 2020s, it will peer at the universe through some of the most sophisticated sunglasses ever designed. This multi-layered technology, the coronagraph instrument, might more rightly be called "starglasses": a system of masks, prisms, detectors and even self-flexing mirrors built to block out the glare from distant stars — and reveal the planets in orbit around them.NASA's Goddard Space Flight CenterStarshadeAnother starlight-snuffing technology is called the starshade. This sunflower-shaped spacecraft, the size of a baseball diamond, would unfold like origami. Parked far from a space telescope, its distinctive shape would block starlight and tamp down any stray light that might otherwise leak around the edges.NASA scientists are working to refine the starshade design so it could be considered for a possible future mission.This artist's concept of a starshade shows how the technology can block starlight and reveal the presence of planets.
Imagine the Universe!
It was the first space observatory to have the capability to observe simultaneously in the gamma-ray, X-ray and visual regions of the em spectrum. Targets include gamma-ray bursts, supernovae and black holes.
International X-ray Observatory (IXO)
A joint mission by NASA, the European Space Agency (ESA), and Japenese Aeropsace Exploration Agency (JAXA), which will combine a large X-ray mirror with new instrumentation. IXO will study the formation of structure in the universe, matter under extreme conditions in black holes and neutron stars, and the life cycles of matter and energy in the universe. Launch is planned for the 2020's.
interstellar medium
The gas and dust between stars, which fills the plane of the Galaxy much like air fills the world we live in. For centuries, scientists believed that the space between the stars was empty. It wasn't until the eighteenth century, when William Herschel observed nebulous patches of sky through his telescope, that serious consideration was given to the notion that interstellar space was something to study. It was only in the last century that observations of interstellar material suggested that it was not even uniformly distributed through space, but that it had a unique structure.
ions 
An atom with one or more electrons stripped off, giving it a net positive charge.
ionic (or ionized) gas
Gas whose atoms have lost or gained electrons, causing them to be electrically charged. In astronomy, this term is most often used to describe the gas around hot stars where the high temperature causes atoms to lose electrons.
IUE
International Ultraviolet Explorer, an ultraviolet space observatory launch in 1978. Originally designed for a 3 year mission, IUE exceeded all expectations and functioned for over 18 years, finally ceasing operation in September 1996.

 Tell me more about IUE.

J
jets
Beams of particles, usually coming from an active galactic nucleus or a pulsar. Unlike a jet airplane, when the stream of gas is in one direction, astrophysical jets come in pairs with each jet aiming in opposite directions.

Catalog of Earth Satellite Orbits
Every few minutes, geostationary satellites like the Geostationary Operational Environmental Satellite (GOES) satellites send information about clouds, water vapor, and wind, and this near-constant stream of information serves as the basis for most weather monitoring and forecasting.

Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales. (NASA images by Marit Jentoft-Nilsen and Robert Simmon.)

Because geostationary satellites are always over a single location, they can also be useful for communication (phones, television, radio). Built and launched by NASA and operated by the National Oceanic and Atmospheric Administration (NOAA), the GOES satellites provide a search and rescue beacon used to help locate ships and airplanes in distress.
Finally, many high Earth orbiting satellites monitor solar activity. The GOES satellites carry a large contingent of “space weather” instruments that take images of the Sun and track magnetic and radiation levels in space around them. 
Other orbital “sweet spots,” just beyond high Earth orbit, are the Lagrange points. At the Lagrange points, the pull of gravity from the Earth cancels out the pull of gravity from the Sun. Anything placed at these points will feel equally pulled toward the Earth and the Sun and will revolve with the Earth around the Sun.
Of the five Lagrange points in the Sun-Earth system, only the last two, called L4 and L5, are stable. A satellite at the other three points is like a ball balanced at the peak of a steep hill: any slight perturbation will push the satellite out of the Lagrange point like the ball rolling down the hill. Satellites at these three points need constant adjustments to stay balanced and in place. Satellites at the last two Lagrange points are more like a ball in a bowl: even if perturbed, they return to the Lagrange point.

Lagrange points are special locations where a satellite will stay stationary relative to the Earth as the satellite and the Earth revolve around the Sun. L1 and L2 are positioned above the day and night sides of the Earth, respectively. L3 is on the other side of the Sun, opposite the Earth.
Imagine the Universe!
For the most part, there haven't been big differences between cultures, and I've found that it's not always easy to categorize people. In fact, I frequently found myself in meetings with men from Holland and Japan who live in New York, two women from Italy and Greece who live in England, a German living in Switzerland, and an Austrian living in Holland.
Who was your favorite teacher in school? What was this teacher like and how did he/she influence your life?
Impossible to answer. I had so many great teachers. The ones I remember best were smart, articulate and cared about both their students and their subjects. They made me think.
What do you think is the most important technological advance that has occurred in your lifetime?
Disposable diapers?
I suppose I'd have to say the internet. I used to use the library and would Xerox articles from bound journals. I used to have to call or get information by mail for everything from movie schedules and airline tickets to road maps. Now I can get archived data from most satellites or exchange information with foreign colleagues almost instantaneously. I'm not sure that it's always a good thing, but I can get almost everything I need without moving from my desk.
What is the one big dream you have, or the one thing that you would like to accomplish during your lifetime?
When I was in high-school my 'dream' was to become a physicist. I thought it was cool and hard. Now, what I want is to have a balanced life. I want to do work that is challenging and that I enjoy. I want my work to be useful and respected. I want my family to be happy. I want time to enjoy all the other interesting things in life.
