The Trump Administration has proposed a $21 billion budget for NASA that is $481 million below the $21.5 billion budget Congress approved last month.

NASA’s spending plan for fiscal year 2020 shifts funding toward the construction of a Lunar Gateway and the return of astronauts to the moon’s surface by 2028.

The request includes cuts in three programs — Space Launch System (SLS), Orion spacecraft and exploration ground systems — that are the foundation of the return to the moon and are considered sacrosanct to Congress.

The Administration is also targeting NASA’s Science, Space Operations and Aeronautics programs for budget cuts. It also proposes to end the space agency’s $110 million STEM Engagement program.

Spending on SLS would be cut by $374.6 million with the Orion program absorbing a $83.3 million reduction. The budget for Exploration Ground Systems (EGS) that support SLS and Orion would also fall by $192.7 million.

NASA said the cuts are a result of deferring work on an upgraded version of SLS.

“The Budget defers upgrades to the SLS known as ‘Block 1B’, which are not needed for missions planned during the first half of the 2020s,” NASA said in a budget document. “Funding is instead focused on completion of the initial version of the SLS and supporting a reliable SLS and Orion annual flight cadence. Deferring the Block 1B upgrades also enables accelerating other exploration activities critical to landing astronauts on the Moon in the 2020s.”

SLS Block 1 can lift 70 metric tons into low Earth orbit (LEO). SLS Block 1B is being designed to lift 105 metric tons to LEO.

In another blow to SLS, the Administration is proposing to save more than $700 million by launching the Europa Clipper orbiter on a commercial rocket. Current law requires the orbiter and a subsequent lander to Jupiter’s frozen world to be launched on SLS.

Given the strong bipartisan support in Congress for the SLS, Orion and EGS, it seems unlikely that legislators will approve a collective cut of $650.6 million. They might also fear that deferring work on the SLS Block 1B would make it easier to cancel the program in the future.

In fact, Congress has previously rejected the Administration’s efforts to slash NASA’s budget. Legislators have instead given the space agency increases.

Shift to the Moon

The space agency’s Exploration Research and Development budget would be increased by $622 million from $958 million to $1.58 billion.  Within that budget, spending on the Lunar Gateway would increase by from $450 million to $821.4 million.

“Gateway funding focuses on developing a small way station that will orbit the Moon and enable lunar landers and surface activities, to include a Power and Propulsion Element by 2022, and habitation, airlock, and logistics elements thereafter,” NASA said in budget document.

Funding for Advanced Cislunar and Surface capabilities (ACSC) would also rise from $116.5 million to $363 million, an increase of $246.5 million.

“ACSC funding focuses on design analysis, technology maturation, system development and integration, and spaceflight demonstrations for a human lunar landing system,” the budget document said. “ACSC is developing human lunar landing, lunar robotic, and surface capabilities through commercial and international partnerships as well as in coordination with other NASA programs.

“This includes leveraging the [Science Mission Directorate] development of smaller landers for capabilities such as navigation and precision landing and investments through exploration technology and the lunar surface initiative,” the document added.

The $1 billion Space Technology budget (which the Trump Administration calls Exploration Technology) supports a new “Lunar Surface Innovation Initiative, which aims to spur the creation of novel technologies needed for lunar surface exploration and accelerate the technology readiness of key systems and components,” NASA said.

The space agency’s Science budget would be cut from $6.9 billion to $6.3 billion, which is a reduction of $602 million. The proposed cutbacks are spread across the planetary, Earth science, astrophysics and heliophysics programs. Only the James Webb Space Telescope would receive a boost.

“The Budget proposes to terminate the Wide Field Infrared Survey Telescope (WFIRST) mission.

“Given delays and cost growth with the James Webb Space Telescope, the Administration is not ready to proceed with another multi-billion-dollar space telescope,” the budget document said.

The budget zeros out the space agency’s $110 million STEM Engagement program to redirect the funds to lunar exploration, a move Congress has rejected in the past. In NASA budget documents, the space agency said it would continue STEM and education efforts being done through other NASA programs.

The Safety, Security and Mission Services (SSMS) budget would be boosted by $329.6 million under the proposed budget.

“NASA is addressing its top SSMS priority by increasing facility maintenance activities at all Centers to reduce risk to missions. Increased funding will help reduce the significant backlog of facility maintenance projects and requirements,” the budget document said. “The FY 2020 request continues NASA’s increased investment in proactive maintenance initiatives such as the conditioned-based maintenance (CBM) program.”

The construction budget would also get a boost of $252.2 million. Projects included in the proposal include the Langley Research Center Flight Dynamics Research Facility, the Flight Electronics Integration Facility at the Jet Propulsion Laboratory, and the Stennis Space Center’s High- Pressure Industrial Water System.

    Given that SLS-Orion schedule slippages not only have not diminished over the first half of Trtump’s current term, but have gotten worse, it is heartening that at least some official acknowledgment of that sad fact is now reflected in the administration’s proposed NASA budget for the next fiscal year. The effort to trim the rations of Shelby’s favorites is unlikely to meet with any actual success this budget cycle. But the fact the effort is even being made is – I think – a warning to Festung Huntsville that more consequential efforts likely lie ahead if business as usual continues to be the order of the day for the program of record.

    tinTrump told his agencies to trim their budgets by 10% or so. He does not remember. The only way to handle the situation is note everything he says and when the time comes, do it. Since the Cabinet will not give him sick leave as the Constitution says to do.

    P.S. My favorite dragon fly friend Green Green the flying machine pulled a good one. He is gorgeous. Green and black, a color combination loved by all. He is a low flyer and likes to play chicken. Taking my walk on my regular path he will get in the way. I tell him: watch out Green. He has done this sometimes on every pass of our 20 min. together. After Rabbit died, I was walking another path to the West and the dragon flies were there. B&W Stripe and a lot of other insects. And Green. He was off the path on the ground. He was lame. 1 wing was at his side and he was dragging it. I think slow sometimes. A day or so later it came to me what he was saying. He was commiserating with me about Rabbit. Plus adding his joke of playing chicken. He was there at the same spot and I told him I was slow, but I had figured out what he was trying to say. I apologized to him for not understanding.

    I hope you are all science people and use the Scientific Method. And give me a maybe. I only give you my observation and thinking. I don’t lie. Perhaps I am seeing things or interpreting wrong. I hope I am correct and have learned something about our animal friends.

    I painted one of my RC gliders like a green dragonfly once. Not exactly, but in the style of, with big yellow “eyes” on the canopy. My all-time favorite paint job I’ve done.

    Dragonflies are cool

    Nothing to get a commercial ISS module(s) going. Haven’t heard much talk about that kind of thing lately.

    Of course the big news is the request for less for ISS and moving Europa Clipper to commercial. And then today’s news regarding a push for a commercially launched EM-1. I wonder if Congress will surrender on any aspect of SLS? I could see them saying EM-1 has to stay on SLS, but since it will take a while to get SLS going, Europa Clipper could go ahead and launch commercially. Or will they just hold firm on all aspects? The new House leadership might not be as on board with SLS as the old crew, so there could be some wiggle room after all the recent (and hopefully continuing) SpaceX successes…

    I hope they keep going with WFIRST. If one of the two big astrophysics missions had to go, I’d be much more willing to write off James Webb myself

    There’s a mistake in the table, Exploration ground systems is going down, it should be red not blue

    I obviously seriously underestimated Bridenstine’s and Pence’s willingness to wade right into The Swamp in order to get things moving.
