Vice President Mike Pence on Tuesday called for NASA to land astronauts on the moon by or before 2024.

Experts called the moonshot idea, which accelerates NASA’s tentative 2028 plans to land astronauts on the moon by three years, ambitious and hugely expensive.

“It is our policy to return American astronauts to the moon,” said Pence in a speech in Huntsville, Alabama, ahead of a meeting of the National Space Council. Pence suggested astronauts should land at the moon’s south pole, where some ice is believed to lie hidden in shadowed craters. Pence told NASA to “fail smarter” in developing the lunar landing.

“It’s definitely a laudable goal, but also very ambitious,” space policy expert Brian Weeden of the Secure World Foundation told BuzzFeed News by email. “I think it might be possible but only with a serious change to the existing plan and Congressional support, including funding.”

NASA has not even been able to launch astronauts into low Earth orbit since the 2011 retirement of the space shuttle program. A private rocket company, SpaceX, is scheduled to return astronauts to the International Space Station later this year.

NASA, a $21 billion agency, now spends about $3.5 billion a year on the jumbo Space Launch System (SLS) rocket and the Orion capsule for delivering astronauts beyond low Earth orbit. The administration had sought to accelerate those efforts in its most recent budget proposal to Congress, partly by cutting $600 million from space science budgets.



“While the Trump Administration is talking big goals for NASA’s human spaceflight program, they’re not being matched [with] increases in budget. And Congress has so far prioritized jobs in certain districts over speed and efficiency,” Weeden said. “I think a big part of the risk is that the push to go faster might lead to short-term success that’s not sustainable.”

The SLS has been repeatedly delayed, and Pence said that if commercial rockets from space firms such as SpaceX or Blue Origin replaced it for moon missions, that was acceptable. That represented a break with past policy for NASA that caught the attention of Elon Musk.
