Forward to the Moon, on to Mars

Overall Principles and Direction 

President Trump’s Fiscal Year 2020 NASA budget is one of 

the strongest on record for our storied agency. 

In keeping with Space Policy Directive-1, it provides for the 

foundation of a national exploration campaign that will use 

the experience of the NASA workforce, coupled with the 

agility and innovation of our commercial and international 

partners, to create an architecture that is open, 

sustainable and agile. This unified effort will inspire 

generations and change the course of history as we 

realize the next great scientific, economic and technical 

achievements in space. 

1
Space Policy Directive One

NASA shall “lead an innovative and sustainable program of 

exploration with commercial and international partners to enable 

human expansion across the solar system and to bring back to Earth 

new knowledge and opportunities. Beginning with missions beyond 

low-Earth orbit, the United States will lead the return of humans to 

the Moon for long-term exploration and utilization, followed by 

human missions to Mars and other destinations.”

2020 Budget Highlights

 Provides $21B, including $10.7B to continue building the key components of 

the Exploration campaign that will send astronauts to the Moon and beyond, 

including: 

 The Space Launch System rocket, a heavy-lift expendable launch vehicle, to 

ensure the rocket is operational in the early 2020s when it will be needed to 

carry astronauts on board the Orion crew capsule to the vicinity of the Moon.

 The Lunar Gateway, an outpost orbiting the Moon in the mid-2020s. 

 Commercial launch capabilities to enable regular, low-cost access to the lunar 

vicinity and surface. 

4

 Lunar landers to 

enable cargo delivery 

and human access to 

the lunar surface by 

the late 2020s.

 Building commercial 

and international 

partnerships
2020 Budget Highlights

 Develops the first elements of Lunar 

Gateway, the Power and Propulsion 

Element, ready for launch in 2022, and the 

Utilization module and ESPRIT enabling 

crew to stay aboard starting in 2024.

 Develops and grows emerging technology and 

commercial capabilities to deliver science and 

technology payloads to the Moon in preparation 

for exploration and further enhance human 

lunar lander capabilities.

 Focuses the SLS program on the completion of 

the initial version of SLS and supporting a 

reliable annual SLS / Orion flight cadence. 

Defers funding of Block 1B for the SLS. 
Highlights (continued)

 The Lunar Surface Innovation Initiative (LSII) 

serves as a catalyst for enabling critical 

technologies required for humans to successfully 

operate on the lunar surface. These include 

surface power and in situ resource utilization.

 Utilizes public-private partnerships to develop a 

human-class lunar lander system that will, along 

with other Exploration Campaign activities, re-

establish U.S. preeminence to, around, and on 

the lunar surface leading to a human lunar 

landing by 2028.

 Develops lunar robotic rover capabilities to 

support science and resource utilization 

investigations, and technology.

 Drives toward a vibrant, U.S-led economy in 

Earth orbit funding the International Space 

Station as well as new commercial space 

capabilities that will facilitate a transition to a 

more robust and cost-effective approach to 

human space activities near the Earth.

System including funding for the next Mars rover 

launch in 2020 and a Europa Clipper mission to 

launch in 2023.

 Initiates a Mars Sample Return Mission to 

retrieve samples from Mars, and return those 

samples with the first launch from another 

planet. 

 Continues exploring the universe with launch of 

James Webb Space Telescope in 2021. 

Provides no funding for WFIRST space 

telescope while Webb is still being built.

 Enables our wide-ranging science work on 

many fronts, which continues to lead the world 

in its size, scope, and scientific output. 

 Consistent with prior budgets, provides no 

funding for PACE, CLARREO-PF, and the Office 

of Science, Technology, Engineering, and 

Mathematics (STEM) Engagement. 

7
Highlights (continued)

 Supports transformative aeronautics technology 

research to boost U.S. technological and 

economic leadership and support high quality 

American jobs including continued development 

of the X-59 QueSST flight demonstrator to help 

usher in a new era of U.S. led supersonic 

transportation.

 Maintains robust investment in air traffic 

management improvements that will safely 

increase air traffic capacity, reduce flight delays, 

and enable safe, robust UAS integration. 

 Replenishes resources for mission enabling 

services and operations, including critical 

investments in maintaining test facilities, 

advancing cybersecurity protections, and 

ensuring safe and reliable operations for NASA's 

objectives in space, science, aeronautics, and 

technology.

 Funds repair, revitalization, demolition, and 

recapitalization projects that reduce the 

Agency’s footprint and provide efficient, 

modernized facilities.

 Invests in energy savings projects to reduce 

utility usage and costs. 

 Constructs new or modified facilities to conduct 

NASA’s program missions, including new 

research facilities at LaRC and JPL.

 Manages NASA’s environmental clean-up responsibilities.

 FY20 budget enables a stronger revitalization strategy to replace older and costly 

facilities, beyond their design life, with more modern and less costly capabilities 

supporting agency mission objectives
Long-Term Exploration and Utilization of the Moon 

(current plan)

With this Budget, by 2028 NASA will have:

• Provided opportunities for at least 13 deep space 

CubeSat missions, including 7 to the Moon (on EM-1)

• Completed 2 Exploration Mission test flights 

with SLS and Orion

• Completed 5 additional EMs on SLS and Orion and 

14 commercial flights

• Flown up to 10 CLPS opportunities, 

enabling new science and demonstrating 

new technologies supporting human return 

to the lunar surface

• Delivered a rover to investigate volatiles

• Demonstrated, for the first time, a reusable 

lunar ascent vehicle

• Used, for the first time on the Moon, key exploration 

technologies including precision landing, cryogenic 

fluid management, in-situ resource utilization, and 

surface nuclear power

• Returned humans to the lunar surface

• Demonstrated key technologies and operations 

needed to 

enable the first human missions to Mars
