When NASA’s Space Launch System (SLS) is fully integrated, assembled, and finished with testing, it will be the most powerful rocket since the Saturn V that carried the Apollo astronauts to the Moon. To get it there, NASA has been conducting a testing campaign known as the Green Run, an 8-step assessment that culminates in a test-firing of all four of the Core’s RS-25 engines (aka. a “Hot Fire” test).
On January 16th, NASA made its first attempt at a Green Run Hot Fire test at the Stennis Space Center’s B-2 Test Stand in Mississippi, which only lasted for about one minute. Another attempt was made on Thursday, March 18th, where all four engines fired for 8 minutes and 19 seconds. This successful fire test is a crucial milestone for the SLS and brings it one step closer to sending astronauts back to the Moon.
In November of 2021, NASA will embark on a new era of space exploration as they make the inaugural launch of the Space Launch System (SLS). When it enters service, this booster will be the most powerful rocket since the Saturn V, which took the Apollo astronauts to the Moon. This is fitting since the SLS will be the rocket returning astronauts to the Moon by 2024 (as part of Project Artemis).
To get the SLS ready for its first launch, NASA has been running the Core Stage through a series of tests designed to test all the systems and components of the heavy-launch system – collectively known as a “Green Run.” The next step in this process will be a second Green Run Hot Fire Test, where all four RS-25 engines on the SLS Core Stage will fire at once to show they can operate as part of a single integrated system.
Today, at close to 04:30 PM local time (CST), NASA achieved a major milestone with the development of the Space Launch System (SLS) – the heavy launch system they will use to send astronauts back to the Moon and crewed missions to Mars. As part of a Green Run Hot Fire Test, all four RS-25 engines on the SLS Core Stage were fired at once as part of the first top-to-bottom integrated test of the stage’s systems.
This test is the last hurdle in an eight-step validation process before the Core Stage can be mated with its Solid Rocket Boosters (SRBs) and sent on its maiden voyage around the Moon (Artemis I) – which is currently scheduled to happen sometime in November of 2021.
With the passage of the NASA Authorization Act of 2010, work began on a launch vehicle that would carry cargo and crews back to the Moon and beyond. This vehicle is known as the Space Launch System (SLS), a heavy-launch system that (once fully operational) will be the most powerful rocket in the world since the Saturn V– the venerable vehicle that took the Apollo astronauts to the Moon.
Unfortunately, the development of the SLS has suffered from multiple delays over the past few years, causing no shortage of complications. However, engineering teams at NASA’s Stennis Space Center near St. Louis, Mississippi, recently completed a Green Run of the SLS’s Core Stage, which involved testing the rocket’s critical systems in preparation for its inaugural launch by November of 2021.
As rockets become more and more powerful, the systems that protect them need to keep pace. NASA will use almost half a million gallons of water to keep the Space Launch System (SLS) safe and stable enough to launch successfully. The system that delivers all that water is called the Ignition Overpressure Protection and Sound Suppression (IOP/SS) water deluge system, and seeing it in action is very impressive.
Aerospace giant Northrop Grumman will acquire Orbital ATK for approximately $9.2 billion, in a deal the companies announced Monday and they say will “expand capability” is largely “complementary” and involves “little overlap.”
Orbital ATK specializes in a wide variety of launch vehicles, satellites, missiles and munitions that Northrop believes will significantly enhance capabilities it lacks while offering Orbital significantly more technical and financial resources to grow sales and business opportunities.
Under the terms of the huge deal West Falls Church, Virginia based Northrop will dole out approximately $7.8 billion in cash to buy Dulles, Virginia based Orbital ATK and assume $1.4 billion in net debt. Orbital ATK shareholders will receive all-cash consideration of $134.50 per share, which is about a 20% premium above the stock’s price of $110 per share at the close of trading Friday, Sept. 15.
Rumors of the deal first appeared on Sunday.
The final purchase is expected to take place around mid-2018, subject to approval by government regulators and Orbital ATK shareholders.
The Boards of Directors of both companies have already given unanimous approval to the mega buyout.
“Our two companies represent a very complementary fit,” Wes Bush, chief executive officer and president of Northrop Grumman said in a conference call on Monday, Sept. 18.
“We have very little overlap, and we fully expect our combined portfolios of leading technologies, along with our aligned and innovation-focused cultures, to yield significant value creation through revenue, cost and operational synergies, accelerating our profitable growth trajectory.”
Northrop indicated that Orbital ATK will operate as a separate fourth unit – at least initially – and that Orbital programs will benefit from the increased financial resources available from Northrup.
“Upon completion of the acquisition, Northrop Grumman plans to establish Orbital ATK as a new, fourth business sector to ensure a strong focus on operating performance and a smooth transition into Northrop Grumman.”
For his part Orbital ATK CEO David Thompson was very pleased with the buyout and future opportunities.
“The agreement reflects the tremendous value that Orbital ATK has created for our customers, our shareholders and our employees,” David Thompson, Orbital ATK president and chief executive officer said at the conference call.
“The combination will allow our team as a new business sector within Northrop Grumman to maintain strong operational performance on existing customer programs and to pursue new opportunities that require greater technical and financial resources than we currently possess.”
“Our collective customers should benefit from the expanded capabilities for innovation, increased speed of delivery and improved affordability of production resulting from the combination.”
“The combination of our companies and human capital will also significantly benefit our customers,” Bush elaborated. “Together, we can offer our customers enhanced mission capabilities and more competitive offerings in areas such as space, missiles and strategic deterrents.
“Our shareholders can expect revenue synergies from these new business opportunities.”
Northrop Grumman sales for 2017 amount to about $25 billion vs. about $4.5 billion for Orbital ATK
Orbital ATK itself is the product of a very recent merger in 2015 of Orbital Sciences and ATK.
The company employs over 13,000 people including over 4,200 scientists and engineers. It holds a heft backlog of contracts worth more than $15 billion.
Northrop Grumman employs over 68,000 people and is the fifth largest defense contractor.
“The agreement will also provide expanded career options for our employees as part of a larger, more diverse aerospace and defense company,” said Thompson.
It will also benefit stockholders.
“The transaction represents a truly compelling financial proposition for our shareholders, valuing the enterprise at about $9.2 billion and providing our investors with more than 120% total return over the 3-year period from the completion of the Orbital ATK merger in early 2015 to the expected closing in the first half of 2018.”
Orbital ATK launchers run the gamut from small to medium to large.
The rockets include the massive solid rocket boosters for NASA’s Space Launch System (SLS) heavy lift rocket under development, the Antares liquid fueled booster used to launch Cygnus cargo freighters to the International Space Station for NASA, the Minotaur family of medium class solid rocket launchers, as well as sounding rockets for a variety of low weight science missions.
The most recent Orbital ATK launch took place on Aug. 26 when a Minotaur 4 rocket (a retired Peacekeeper ICBM) lifted off from Cape Canaveral with a USAF surveillance satellite.
Orbital ATK also has a thriving satellite manufacturing business building NASA science, commercial, government and military satellites.
The purchase is also estimated to result in $150 million in annual cost savings by 2020.
“We believe that this combination represents a compelling value creation opportunity for the customers, shareholders and employees of both our companies,” stated Bush. “Through our combination, all of our stakeholders will benefit from expanded capabilities, accelerated innovation and greater competitiveness in critical global security domains.”
Watch for Ken’s continuing onsite NASA mission and launch reports direct from the Kennedy Space Center, and Cape Canaveral Air Force Station, Florida, and NASA Wallops Flight Facility, Va.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.
NASA is in an awkward in-between time right now. Since the beginning of the space age, the agency has had the ability to send its astronauts into space. The first American to go to space, Alan Shepard, did a suborbital launch on board a Mercury Redstone rocket in 1961.
Then the rest of the Mercury astronauts went on Atlas rockets, and then the Gemini astronauts flew on various Titan rockets. NASA’s ability to hurl people and their equipment into space took a quantum leap with the enormous Saturn V rocket used in the Apollo program.
It’s difficult to properly comprehend just how powerful the Saturn V was, so I’ll give you some examples of things this monster could launch. A single Saturn V could blast 122,000 kilograms or 269,000 pounds into low-Earth orbit, or send 49,000 kilograms or 107,000 pounds on a transfer orbit to the Moon.
Instead of continuing on with the Saturn program, NASA decided to shift gears and build the mostly reusable space shuttle. Although it was shorter than the Saturn V, the space shuttle with its twin external solid rocket boosters could put 27,500 kilograms or 60,000 pounds into Low Earth orbit. Not too bad.
And then, in 2011, the space shuttle program wrapped up. And with it, the United States’ ability to launch humans into the space. And most importantly, to send astronauts to the continuously inhabited International Space Station. That task has fallen to Russian rockets until the US builds back the capability for human spaceflight.
Since the cancellation of the shuttle, NASA’s workforce of engineers and rocket scientists has been developing the next heavy lift vehicle in NASA’s line up: the Space Launch System.
The SLS looks like a cross between a Saturn V and the space shuttle. It has the same familiar solid rocket boosters, but instead of the space shuttle orbiter and its orange external fuel tank, the SLS has the central Core Stage. It has 4 of the space shuttle’s RS-25 Liquid Oxygen engines.
Although two shuttle orbiters were lost in disasters, these engines and their liquid oxygen and liquid hydrogen performed perfectly for 135 flights. NASA knows how to use them, and how to use them safely.
The very first configuration of the SLS, known as the Block 1, should have the ability to put about 70 metric tonnes into Low Earth Orbit. And that’s just the beginning, and it’s just an estimate. Over time, NASA will increase its capabilities and launch power to match more and more ambitious missions and destinations. With more launches, they’ll get a better sense of what this thing is capable of.
After the Block 1 is launching, NASA will develop the Block 1b, which puts a much larger upper stage on top of the same core stage. This upper stage will have a larger fairing and more powerful second stage engines, capable of putting 97.5 metric tonnes into low Earth orbit.
Finally, there’s the Block 2, with an even larger launch fairing, and more powerful upper stage. It should blast 143 tonnes into low Earth orbit. Probably. NASA is developing this version as a 130 tonne-class rocket.
With this much launch capacity, what could be done with it? What kinds of missions become possible on a rocket this powerful?
The main goal for SLS is to send humans out, beyond low Earth orbit. Ideally to Mars in the 2030s, but it could also go to asteroids, the Moon, whatever you like. And as you’ll read later on in this article, it could send some amazing scientific missions out there too.
The very first flight for SLS, called Exploration Mission 1, will be to put the new Orion crew module into a trajectory that takes it around the Moon. In a very similar flight to Apollo 8. But there won’t be any humans, just the unmanned Orion module and a bunch of cubesats coming along for the ride. Orion will spend about 3 weeks in space, including about 6 days in a retrograde orbit around the Moon.
If all goes well, the first use of the SLS with the Orion crew module will happen some time in 2019. But also, don’t be surprised if it gets pushed back, that’s the name of the game.
After Exploration Mission 1, there’s be EM-2, which should happen a few years after that. This’ll be the first time humans get into an Orion crew module and take a flight to space. They’ll spend 21 days in a lunar orbit, and deliver the first component of the future Deep Space Gateway, which will be the subject of a future article.
From there, the future is unclear, but SLS will provide the capability to put various habitats and space stations into cislunar space, opening up the future of human space exploration of the Solar System.
Now you know where SLS is probably headed. But the key to this hardware is that it gives NASA raw capability to put humans and robots into space. Not just here on Earth, but way across the Solar System. New space telescopes, robotic explorers, rovers, orbiters and even human habitats.
In a recent study called “The Space Launch System Capabilities for Beyond Earth Missions,” a team of engineers mapped out what the SLS should be capable of putting into the Solar System.
For example, Saturn is a difficult planet to reach, and it order to get there, NASA’s Cassini spacecraft needed to do several gravitational slingshots around Earth and one past Jupiter. It took almost 7 years to get to Saturn.
SLS could send missions to Saturn on more direct trajectory, cutting the flight time down to just 4 years. Block 1 could send 2.7 tonnes to Saturn, while Block 1b could loft 5.1 tonnes.
NASA is considering a mission to Jupiter’s Trojan asteroids. These are a collection of space rocks trapped in Jupiter’s L4/L5 Lagrange points, and could be a fascinating place to study. Once put into the Trojan region, a mission could visit several different asteroids, sampling a vast range of rocks that detail the Solar System’s early history.
The Block 1 could put almost 3.97 tonnes into these orbits, while the Block 1b could do 7.59 tonnes. That’s 6 times the capability of an Atlas V. A mission like this would have a cruise time of 10 years.
In a previous video, we talked about future Uranus and Neptune missions, and how a single SLS could send spacecraft to both planets simultaneously.
Another idea that I really like is an inflatable habitat from Bigelow Aerospace. The BA-2100 module would be a fully self-contained space habitat. No need for other modules, this monster would be 65 to 100 tonnes, and would go up in a single launch of SLS. Once inflated, it would contain 2,250 cubic meters, which is almost 3 times the total living space of the International Space Station.
One of the most exciting missions, to me, is a next generation space telescope. Something that would be the true spiritual successor to the Hubble Space Telescope. There are a few proposals in the works right now, but the idea I like best is the LUVOIR telescope, which would have a mirror that measures 16 meters across.
The SLS Block 1b could put 36.9 tonnes into Sun-Earth Lagrange Point 2. Really there’s nothing else out there that could put this much mass into that orbit.
Just for comparison, Hubble has a mirror of 2.4 meters across, and James Webb is 6.5. With LUVOIR, you would have 10 times more resolution than James Webb, and 300 times more power than Hubble. But like Hubble, it would be capable of seeing the Universe in visible and other wavelengths.
A telescope like this could directly image the event horizons of supermassive black holes, see right to the edge of the observable Universe and watch the first galaxies forming their first stars. It could directly observe planets orbiting other stars and help us determine if they have life on them.
Seriously, I want this telescope.
At this point, I know this is going to set off a big argument about NASA versus SpaceX versus other private launch providers. That’s fine, I get it. And the Falcon Heavy is expected to launch later this year, bringing heavy lift launch capabilities at an affordable price. It’ll be able to loft 54,000 kilograms, which is less than the SLS Block 1, and almost a third of the capability of the Block 2. Blue Origins has its New Glenn, there are heavier rockets in the works from United Launch Alliance, Arianespace, the Russian Space Agency, and even the Chinese. The future of heavy lift has never been more exciting.
If SpaceX does get the Interplanetary Transport Ship going, with 300 tonnes into orbit on a reusable rocket. Well then, everything changes. Everything.
In order to get a better idea of the implications of the 2018 NASA budget proposal for KSC, I spoke one-on-one with Robert Cabana – one of NASA’s top officials, who currently serves as Director of the Kennedy Space Center (KSC) as well as being a former astronaut and Space Shuttle Commander. Cabana is a veteran of four space shuttle missions.
How did NASA and KSC fare with the newly announced 2018 Budget?
“We at KSC and NASA as a whole did very well with the 2018 budget,” KSC Director Robert Cabana explained during an interview with Universe Today by the Rocket Garden at the Kennedy Space Center Visitor Complex (KSCVC) in Florida.
“I think it really solidifies that the President has confidence in us, on the path that we are on,” Cabana noted while attending a student robotics competition at KSCVC sponsored by NASA.
“With only a 1 percent cut – when you look at what other agency’s got cut – this budget allows us to stay on the path that we are on.”
Trump cut NASA’s 2018 budget request by $0.5 Billion compared to the recently enacted FY 2017 budget of $19.6 Billion approved by the US Congress and signed by the President.
Other Federal science agency’s also critically vital to the health of US scientific research such as the NIH, the NSF, the EPA, DOE and NIST suffered terrible double digit slashes of 10 to 20% or more.
KSC is the focal point for NASA’s human spaceflight programs currently under intense development by NASA – namely the Space Launch System (SLS) Mars megarocket, the Orion deep space crew capsule to be launched beyond Earth orbit (BEO) atop SLS, and the duo of Commercial Crew Program (CCP) space taxis being manufactured by Boeing and SpaceX that will ferry our astronauts to low Earth orbit (LEO) and the International Space Station (ISS).
Numerous NASA science missions also launch from the Florida Space Coast.
“At KSC the budget keeps us on a path that continues to provide a commercial crew vehicle to fly crews to the ISS in 2018,” Cabana stated.
“The budget also keeps us on track to launch SLS and Orion in 2019.”
“I think that’s really important – along with all the other stuff we are doing here at KSC.”
“From our point of view it’s a good budget. We need to press ahead and continue on with what we promised.”
What’s ahead for commercial crew at KSC?
“We are moving forward with commercial crew,” Cabana told me.
“Within the next calendar year  we are moving ahead with flying the first certification flight with crew to the ISS. So that’s test flights and by the end of the year an actual crewed flight to the ISS. I want to see that happen.”
Industry partners Boeing and SpaceX are building the private CST-100 Starliner and Crew Dragon spaceships respectively, as part of NASA’s commercial crew initiative aimed at restoring America’s human spaceflight capability to launch our astronauts aboard American spaceships on American rockets from American soil.
Commercial Crew is a public/private partnership initiative with commercial contracts valued at $4.2 Billion and signed by Boeing and SpaceX with NASA in September 2014 under the Obama Administration.
The goal of commercial crew is to end our sole reliance on the Russian Soyuz capsule for astronaut flights to the space station since the retirement of the space shuttles back in 2011 – by manufacturing indigenous rockets and human rated spaceships.
However the CCP program suffered severe budget reductions by the US Congress for several years which forced significant work stretch-outs and delays in the maiden crew launches by both companies from 2015 to 2018 – and thus forced additional payments to the Russians for Soyuz seat purchases.
Both the Boeing Starliner and SpaceX Dragon crew vehicles can carry 4 or more astronauts to the ISS. This will enable NASA to add another crew member and thereby enlarge the ISS crew from 6 to 7 permanent residents after they become operational.
Meanwhile NASA is focusing on developing the SLS heavy lift rocket and Orion crew capsule with prime contractors Boeing and Lockheed Martin in an agency wide effort to send humans on a ‘Journey to Mars’ in the 2030s.
The European Space Agency(ESA) is also partnered with NASA and providing the service module for Orion.
What’s the status of the delivery of the European Space Agency’s service module?
“The service module will be here sometime next year,” Cabana said.
He noted that the details and exact timing are yet to be determined.
The first integrated launch of SLS and Orion on the unpiloted Exploration Mission-1 (EM-1) is now slated for sometime in 2019 after NASA recently slipped the date to the right from Fall 2018.
I asked Cabana for his insight and opinion on NASA not adding crew to Orion on the EM-1 flight.
“No we are not launching crew on the first flight [EM-1],” Cabana stated.
“With the budget that we have and what we need to do, this is the answer we got to at the end.”
“You know the crew study was still very important. It allowed us to find some things that we should still do on [EM-1], even though we are not going to launch crew on that flight.
“So we will make some further modifications that will reduce the risk even further when we do fly crew [on the next flight of EM-2].”
So for 2017 what are the major milestone you hope to complete here at KSC for SLS and Orion?
“So for me here at the Kennedy Space Center, my goal for the end of this calendar year 2017 we will have completed all of the construction of all of the [ground systems] hardware and facilities that are necessary to process and launch the Space Launch System (SLS) and Orion,” Cabana elaborated.
‘We will still have a lot of work to do with the software for the spacecraft command and control systems and the ground systems.”
“But my goal is to have the hardware for the ground systems complete by the end of this year.”
What are those KSC facilities?
“Those facilities include the VAB [Vehicle Assembly Building] which will be complete to accept the mobile launcher in September and pad 39B will be complete in August,” Cabana said.
“The RPSF is already complete. The NPFF is already complete and we are doing testing in there. The LASF [Launch Abort System Facility] is complete – where they put the abort rocket on.”
“The Mobile Launcher will be complete from a structural point of view, with all the systems installed by the end of the year [including the umbilical’s and while room].”

The Trump Administration has proposed a $19.1 Billion NASA budget request for Fiscal Year 2018, which amounts to a $0.5 Billion reduction compared to the recently enacted FY 2017 NASA Budget. Although it maintains many programs such as human spaceflight, planetary science and the Webb telescope, the budget also specifies significant cuts and terminations to NASA’s Earth Science and manned Asteroid redirect mission as well as the complete elimination of the Education Office.
Overall NASA’s FY 2018 budget is cut approximately 3%, or $560 million, for the upcoming fiscal year starting in October 2017 as part of the Trump Administration’s US Federal Budget proposal rolled out on May 23, and quite similar to the initial outline released in March.
The cuts to NASA are smaller compared to other Federal science agencies also absolutely vital to the health of US scientific research – such as the NIH, the NSF, the EPA, DOE and NIST which suffer unconscionable double digit slashes of 10 to 20% or more.
The highlights of NASA’s FY 2018 Budget were announced by NASA acting administrator Robert Lightfoot during a ‘State of NASA’ speech to agency employees held at NASA HQ, Washington, D.C. and broadcast to the public live on NASA TV.
Lightfoot’s message to NASA and space enthusiasts was upbeat overall.
“What this budget tells us to do is to keep going!” NASA acting administrator Robert Lightfoot said.
“Keep doing what we’ve been doing. It’s very important for us to maintain that course and move forward as an agency with all the great things we’re doing.”
“I want to reiterate how proud I am of all of you for your hard work – which is making a real difference around the world. NASA is leading the world in space exploration, and that is only possible through all of your efforts, every day.”
“We’re pleased by our top line number of $19.1 billion, which reflects the President’s confidence in our direction and the importance of everything we’ve been achieving.”
Thus Lightfoot’s vision for NASA has three great purposes – Discover, Explore, and Develop.
“NASA has a historic and enduring purpose. It can be summarized in three major strategic thrusts: Discover, Explore, and Develop. These correspond to our missions of scientific discovery, missions of exploration, and missions of new technology development in aeronautics and space systems.”
“We’ve had a horizon goal for some time now of reaching Mars, and this budget sustains that work and also provides the resources to keep exploring our solar system and look beyond it.”
Lightfoot also pointed to upcoming near term science missions- highlighting a pair of Mars landers – InSIGHT launching next year as well as the Mars 2020 rover. Also NASA’s next great astronomical observatory – the James Webb Space Telescope (JWST).
“In science, this budget supports approximately 100 missions: 40 missions currently preparing for launch & 60 operating missions.”
“The James Webb Space Telescope is built!” Lightfoot gleefully announced.
“It’s done testing at Goddard and now has moved to Johnson for tests to simulate the vacuum of space.”
JWST is the scientific successor to the Hubble Space Telescope and slated for launch in Oct. 2018. The budget maintains steady support for Webb.
The Planetary Sciences division receives excellent support with a $1.9 Billion budget request. It includes solid support for the two flagship missions – Mars 2020 and Europa Clipper as well as the two new Discovery class missions selected -Lucy and Psyche.
“The budget keeps us on track for the next selection for the New Frontiers program, and includes formulation of a mission to Jupiter’s moon Europa.”
“SLS and Orion are making great progress. They are far beyond concepts, and as I mentioned, components are being tested in multiple ways right now as we move toward the first flight of that integrated system.”
NASA is currently targeting the first integrated launch of SLS and Orion on the uncrewed Exploration Mission-1 (EM-1) for sometime in 2019.
NASA would have needed an additional $600 to $900 to upgrade EM-1 with humans.
Unfortunately Trump’s FY 2018 NASA budget calls for a slight reduction in development funding for both SLS and Orion – thus making a crewed EM-1 flight fiscally unviable.
The budget request does maintain full funding for both of NASA’s commercial crew vehicles planned to restore launching astronauts to low Earth orbit (LEO) and the ISS from US soil on US rockets – namely the crewed Dragon and CST-100 Starliner – currently under development by SpaceX and Boeing – thus ending our sole reliance on Russian Soyuz for manned launches.
“Working with commercial partners, NASA will fly astronauts from American soil on the first new crew transportation systems in a generation in the next couple of years.”
“We need commercial partners to succeed in low-Earth orbit, and we also need the SLS and Orion to take us deeper into space than ever before.”
However the Trump Administration has terminated NASA’s somewhat controversial plans for the Asteroid Redirect Mission (ARM) – initiated under the Obama Administration – to robotically retrieve a near Earth asteroid and redirect it to lunar orbit for a visit by a crewed Orion to gather unique asteroidal samples.
“While we are ending formulation of a mission to an asteroid, known as the Asteroid Redirect Mission, many of the central technologies in development for that mission will continue, as they constitute vital capabilities needed for future human deep space missions.”
Key among those vital capabilities to be retained and funded going forward is Solar Electric Propulsion (SEP).
“Solar electric propulsion (SEP) for our deep space missions is moving ahead as a key lynchpin.”
The Trump Administration’s well known dislike for Earth science and disdain of climate change has manifested itself in the form of the termination of 5 current and upcoming science missions.
NASA’s FY 2018 Earth Science budget suffers a $171 million cut to $1.8 Billion.
“While we are not proposing to move forward with Orbiting Carbon Observatory-3 (OCO-3), Plankton, Aerosol, Cloud, ocean Ecosystem (PACE), Climate Absolute Radiance and Refractivity Observatory Pathfinder (CLARREO PF), and the Radiation Budget Instrument (RBI), this budget still includes significant Earth Science efforts, including 18 Earth observing missions in space as well as airborne missions.”
The DSCOVR Earth-viewing instruments will also be shut down.
NASA’s Office of Education will also be terminated completely under the proposed FY 2018 budget and the $115 million of funding excised.
“While this budget no longer supports the formal Office of Education, NASA will continue to inspire the next generation through its missions and the many ways that our work excites and encourages discovery by learners and educators. Let me tell you, we are as committed to inspiring the next generation as ever.”
Congress will now have its say and a number of Senators, including Republicans says Trumps budget is DOA.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.
The announcement to forgo adding crew to the flight dubbed Exploration Mission-1 (EM-1) was made by NASA acting Administrator Robert Lightfoot during a briefing with reporters on May 13.
“We appreciate the opportunity to evaluate the possibility of this crewed flight,” said NASA acting Administrator Robert Lightfoot during the briefing.
“The bi-partisan support of Congress and the President for our efforts to send astronauts deeper into the solar system than we have ever gone before is valued and does not go unnoticed. Presidential support for space has been strong.”
Although the outcome of the study determined that NASA could be “technically capable of launching crew on EM-1,” top agency leaders decided that there was too much additional cost and technical risk to accommodate and retire in the limited time span allowed.
Lightfoot said it would cost in the range of $600 to $900 million to add the life support systems, display panels and other gear required to Orion and SLS in order to enable adding astronauts to EM-1.
“It would be difficult to accommodate changes needed to add crew at this point in mission planning.”
Thus NASA will continue implementing the current baseline plan for EM-1 that will eventually lead to deep space human exploration missions starting with the follow on EM-2 mission which will be crewed.
Had the crewed lunar SLS/Orion flight been approved it would have roughly coincided with the 50th anniversary the first human lunar landing by NASA astronauts Neil Armstrong and Buzz Aldrin during the Apollo 11 mission in July 1969.
Instead NASA will keep to the agencies current flight plan.
The first SLS/Orion crewed flight is slated for Exploration Mission-2 (EM-2) launching no earlier than 2021.
If crew had been added to EM-1 it would have essentially adopted the mission profile currently planned for Orion EM-2.
“If the agency decides to put crew on the first flight, the mission profile for Exploration Mission-2 would likely replace it, which is an approximately eight-day mission with a multi-translunar injection with a free return trajectory,” said NASA earlier. It would be similar to Apollo 8 and Apollo 13.
Orion is designed to send astronauts deeper into space than ever before, including missions to the Moon, asteroids and the Red Planet.
NASA is developing SLS and Orion for sending humans initially to cislunar space and eventually on a ‘Journey to Mars’ in the 2030s.
They are but the first hardware elements required to carry out such an ambitious initiative.
