Critics of President Obama as a big-government champion certainly aren’t talking about about space exploration, which he seems content to leave to Elon Musk and other private market entities. There’s little doubt that Space X is more cost effective than NASA’s Space Launch System will be, but corporations can change course on projects based on economics, personnel and stock prices, whereas the government has to stay the course. Probably best to have a competition between public and private. That should be the new Space Race. From the Economist:

“SpaceX, the most successful of the private firms, is planning to build a super-heavy Falcon rocket of its own that would be even beefier than the SLS. If all goes to plan, the so-called Falcon XX could reach lunar orbit in the early 2020s and go on to Mars later in the decade, ten years ahead of the SLS. SpaceX already has the lowest launch costs in the industry. It is working on making its rockets reusable, which would cut prices even further. Some (admittedly speculative) estimates say that NASA could cut its costs by a factor of 25 or 50 by going with the Falcon XX rocket instead of the (non-reusable) SLS.

But this is not just an argument about money and jobs. The charitable interpretation of Congress’s plan is that it takes its inspiration from the greatness of the government-run Apollo programme. But Mr Musk is equally forceful when he says that ‘NASA’s most valuable role is to fund advanced science projects such as the Hubble space telescope or the Curiosity Mars rover—things that are valuable for humanity as a whole [and] where there’s not an obvious commercial transaction.’ The rest, in other words, including colonising Mars, Mr Musk’s ultimate aspiration, should be left to entrepreneurs.”
