On Tuesday, the U.S. Senate backed President Trump’s budget bill, giving a significant boost to NASA’s Artemis program. This includes an extra $10 billion aimed at expanding missions to the Moon and beyond.
The funding will help develop more Space Launch System (SLS) rockets and fund a lunar orbiting station called Gateway. This decision comes despite calls from people like SpaceX CEO Elon Musk for a shift to more innovative technologies. Musk has criticized the SLS program, arguing it is inefficient since the rockets are used only once, unlike SpaceX’s reusable rockets. Musk once pointed out that launching an SLS rocket essentially destroys a billion-dollar asset each time.
Recent reports have shown that the cost of launching an SLS can be even higher, estimating it around $2.5 billion per launch. So far, approximately $24 billion has been invested in the SLS program, mainly benefiting major aerospace companies like Boeing and Northrop Grumman.
During Senate confirmation hearings, Jared Isaacman, who was once nominated to lead NASA, raised questions about such enormous expenditures. While he supports using the SLS for a couple of upcoming Artemis missions, he believes that it’s not the best long-term solution for lunar and Mars travel.
The budget bill reflects Congress and the Trump administration’s continued commitment to the SLS. Of the new funding, about $4.1 billion will go to more SLS rockets for the Artemis 4 and 5 missions, while around $2.6 billion will help finish the Gateway station.
Interestingly, in May, the president suggested phasing out the SLS and Orion spacecraft after the Artemis III mission. This new funding seems to contradict that earlier proposal, which emerged before the fallout between Musk and Trump began.
The revised budget also sets aside funds for other exciting projects, including $700 million for a Mars Telecommunications Orbiter and $325 million to SpaceX for a spacecraft designed to help de-orbit the International Space Station (ISS) by the end of the decade.
This ongoing debate about the future of space exploration reflects tensions in the industry. As technologies evolve, the question remains: Are we making the best investments to reach further into space?
