The first all-private mission to the ISS a huge step forward in commercial space travel
The astronauts on board are all private citizens
The crew
Theastronautson board are all private citizens, with the mission commander, Michael López-Alegría, a previous Nasa astronaut. The other three members, Larry Connor, Eytan Stibbe, and Mark Pathy are described by the company as “entrepreneurs” and “investors”.
Although if you are thinking of a stereotypical suited investor going into space, then think again. The backgrounds of these three men are very impressive and suggest any of them could already have been chosen as a space agency astronaut, with a private pilot and a military pilot among them.
Looking more into their backgrounds, it is clear that philanthropy is at the heart of those chosen for this mission, with each known for giving back to their communities. As part of this, theastronauts are planningto carry out research during their time at the ISS looking at how space travel will affect the health of future astronauts – including effects on vision, pain and sleep. Experiments on food growth are also planned – all of which are current topics that need researching for future private space endeavours.
This is a very positive and welcome step forwards. It is usually the case that space agency-collected data is madeavailable to researchers(usually after an embargo period). If private researchers are willing to do the same then it heralds an age of accelerated research and technology.
First private space station
The Ax-1 mission is the first part of a plan by Axiom Space to produce the first private space station. This is no small feat; ISS itself had to bebuilt in pieces, then sent up to be constructed in space. The total mass of a 420 tonnes space station simply isn’t feasible to launch into space in one trip. For comparison, this is the same as launching 70James Webb Space Telescopesat once.
It took over ten years and 30 launches to finish the ISS. Axiom’s plan is to actually construct the space station onboard the ISS, initially building ahabitation module (Axiom Hub One), which is estimated for launch in 2024. No doubt, once operational, this module will accommodate and join with more modules as funding comes in for the company.
With the ISS planned for decommissioning sometime after 2030, there will be a need for an open and international space station. While a space station costs a lot to maintain, Nasa and Esa at least will likelypay a rental feeto use facilities on such a private space station.
A lot of private firms will be watching the Ax-1 mission to make a decision on whether to pursue their own programs. Success would mean that there could suddenly be an influx of investment and plans for future space station modules or entire stations. If this is the case, space agencies will have to accept that they will not be able to compete with the private sector. Instead, they would be wise to focus on renting private space and performing open access research.
I wish the first four private astronauts luck with their mission and hope they bring lots of data back for both researchers and the general public to learn from.
