Washington — The Trump administration has asked Congress to increase National Aeronautics and Space Administration (Nasa) spending in 2020 by an extra $1.6bn as a “down payment” to accommodate the accelerated goal of returning Americans to the surface of the moon by 2024.

The increased funding request, announced by President Donald Trump on Twitter, comes nearly two months after vice-president Mike Pence declared the objective of shortening by four years Nasa’s previous timeline for putting astronauts back on the moon for the first time since 1972.

The proposed increase would bring Nasa’s total spending level for the 2020 fiscal year to $22.6bn. The bulk of the increase is earmarked for research and development of a human lunar landing system, according to a summary provided by Nasa.

“Under my administration, we are restoring @NASA to greatness and we are going back to the Moon, then Mars,” Trump tweeted on Monday. “I am updating my budget to include an additional $1.6bn so that we can return to Space in a BIG WAY!”

Nasa previously aimed to return crewed spacecraft to the lunar surface by 2028, after first putting a “gateway” station into orbit around the moon by 2024.

The newly accelerated goal — an endeavour likely to cost tens of billions of dollars — comes as Nasa has struggled with the help of private partners to resume human space missions from US soil for the first time since the shuttle programme ended in 2011.

Nasa administrator Jim Bridenstine called the revised funding request a “down payment of confidence” from the White House.

“Our goal here is to build a programme that gets us to the moon as soon as possible,” Bridenstine told reporters on a telephone conference call on Monday. “In the coming years, we will need additional funds. But this is a good amount that gets us out of the gate in a very strong fashion.”

‘Risky timelines’

Phil Larson, a former space policy adviser under Trump’s Democratic predecessor, Barack Obama, questioned whether Congress had fully embraced Trump’s ambition to speed up human lunar exploration.

“I’m worried that without proper congressional buy-in, this budget amendment is at best, a massive waste of time, and at worst, pushing risky political timelines that could set Nasa back for years," Larson said.

Bridenstine said $651m of the extra funding would go toward Nasa’s space launch system — the super-heavy rocket whose decade-long development led by Boeing has been hampered by delays and cost overruns — as well as design and construction of a new crew capsule called Orion.

The US Apollo programme, Nasa’s forerunner to the effort at returning humans to Earth’s natural satellite, tallied six manned missions to the moon from 1969 to 1972.

So far, only two other nations have conducted controlled “soft” landings on the moon — the former Soviet Union and China — but those were with unmanned robot vehicles.

Bridenstine said he was optimistic that Trump’s request would draw bipartisan support on Capitol Hill.

The amendment envisions a simplified blueprint for the Lunar Gateway, the planned space outpost in lunar orbit that will serve as a stepping stone for sending astronauts to the moon’s surface.

Nasa officials said they would turn to private companies such as Lockheed Martin, Boeing and Jeff Bezos’s Blue Origin for proposals on the design of the gateway and the human landing system.

Bezos, the richest person in the world and founder of Amazon.com, unveiled last Thursday his space company’s mock-up of a lunar lander being built by Blue Origin.

Bridenstine capped Monday’s media call by announcing that Nasa’s latest lunar initiative would be named Artemis, the goddess of the hunt and of the moon in Greek mythology and the twin sister of Apollo.
