Axiom’s Private ISS Mission Was No Space Vacation

April 25, 2022 by Tom Nardi 14 Comments

In an era where anyone with deep enough pockets can hitch a ride to the edge of space and back, you’d be forgiven for thinking that Axiom’s Ax-1 mission to the International Space Station was little more than a pleasure cruise for the four crew members. Granted it’s a higher and faster flight than the suborbital hops that the likes of William Shatner and Jeff Bezos have been embarking on, but surely it must still be little more than a publicity stunt organized by folks with more money than they know what to do with?

Thankfully, there’s a bit more to it than that. While the mission was privately funded, the Ax-1 crew weren’t just orbital sightseers. For one thing, there was plenty of real-world experience packed into the SpaceX Dragon: the mission was commanded by Michael López-Alegría, a veteran NASA astronaut, and crew members Larry Connor and Eytan Stibbe are both accomplished pilots, with the latter clocking in thousands of hours on various fighter jets during his time with the Israeli Air Force.

But more importantly, they had work to do. Each member of the crew was assigned a list of experiments they were to conduct, ranging from medical observations to the testing of new hardware. Of course there was some downtime — after all, if you spent $50 million on a ticket to space, you’d expect to have at least a little fun — but this wasn’t just a photo op: Axiom was looking for results. There was no hiding from the boss either, as López-Alegría is not just the Mission Commander, he’s also Axiom’s Vice President of Business Development.

Which makes sense when you consider the company’s ultimate goal is to use the ISS as a springboard to accelerate the development of their own commercial space station. The data collected during Ax-1 is going to be critical to Axiom’s path forward, and with their first module already under construction and expected to launch by 2025, there’s no time to waste.

So what did the crew members of the this privately funded mission to the International Space Station accomplish? Let’s take a look at a few of the more interesting entries from the docket.

Spacing Out: Launch Successes And Failures, Next Stop Mars, Rocket Catching, & Space Stations

As large sections of the globe have seen themselves plunged into further resurgences of the pandemic over the past few weeks there has been no let-up in the world of space exploration even for the Christmas holidays, so here we are with another Spacing Out column in which we take a look at what’s going up, what’s flying overhead, and what’s coming down.

December was eventful, with China returning lunar samples and Japan doing the same with asteroid dust. And it was reported that we might just possibly have detected radio waves from ET. The truth may be out there and we sincerely want to believe, but this widely reported signal from Proxima Centauri probably isn’t the confirmation of alien life we’ve all been waiting for.

There has been no shortage of launches over the last month from the usual agencies and companies, with a first launch from China of their Long March 8 heavy lift rocket from the Wenchang launch site in Hainan Province. Its payload of five satellites made it safely to orbit, and we expect the rocket will be a workhorse of their future exploration programme. Meanwhile SpaceX conducted a high-altitude test of their Starship SN8 vehicle, which proceeded according to plan until the craft was approaching the landing pad, at which point the failure of one of its engines to fire caused a spectacular crash. This does not equate to an unsuccessful test flight as it performed faultlessly in the rest of its manoeuvres, but it certainly made for some impressive video.

On the subject of SpaceX and Starship, Elon Musk has said he will sell all his personal property to fund a Martian colony. This will require a fleet of up to 1000 Starships, with three launches a day to ferry both colonists and supplies to the Red Planet. He attracted controversy though by saying that interplanetary immigration would be open to people of all means with loans available for the estimated $50,000 one-way travel cost, and Martian jobs on offer to enable the debt to be paid. Many critics replied to his Tweets likening the idea to indentured servitude. It’s worth remembering that Musk is the master of the grand publicity stunt, and while it seems a good bet that SpaceX will indeed reach Mars, it’s also not inconceivable that his timeline and plans might be somewhat optimistic.

A more tangible story from SpaceX comes in their super heavy booster rocket, which is to be reusable in the same manner as their existing Falcon 9, but not landing on its own legs in the manner of the earlier rocket. It will instead dock with its launch tower, being caught by the same support structures used to stabilise it before launch. At first glance this might seem too difficult to succeed, but no doubt people expressed the same doubts before the Falcon 9s performed their synchronised landings.

Finally away from more troubling developments in the political field, The Hill takes a look at some of those likely to have a hand in providing a commercial replacement for the ISS when it eventually reaches the end of its life. They examine the likely funding for NASA’s tenancy on the station, and looked at the cluster of Texas-based companies gearing up for space station manufacture. That’s right — space station modules from the likes of Axiom Space will become a manufactured assembly rather than one-off commissions. The decades beyond the ISS’s current 2030 projected end of life are likely to have some exciting developments in orbit.

The coming year is likely to be an exciting one, with a brace of missions heading to Mars for February as well as a new space station to catch our attention. The Chinese aren’t content to stop at the Moon, with their Tianwen-1 Mars mission due to start exploring our planetary neighbour, and the first Tianhe module of what will become their much larger space station taking to the skies in the coming year. Meanwhile the Red planet will see NASA’s Perseverance rover also reaching its surface, taking with it the Ingenuity helicopter. Finally, the United Arab Emirates’ Hope probe will go into orbit, making the second month one that should have plenty of news.

Wherever you are, keep yourself safe from Earth-bound viruses, and keep looking at the skies in 2021.

Expanding, And Eventually Replacing, The International Space Station

March 3, 2020 by Tom Nardi 98 Comments

Aboard the International Space Station (ISS), humanity has managed to maintain an uninterrupted foothold in low Earth orbit for just shy of 20 years. There are people reading these words who have had the ISS orbiting overhead for their entire lives, the first generation born into a truly spacefaring civilization.

But as the saying goes, what goes up must eventually come down. The ISS is at too low of an altitude to remain in orbit indefinitely, and core modules of the structure are already operating years beyond their original design lifetimes. As difficult a decision as it might be for the countries involved, in the not too distant future the $150 billion orbiting outpost will have to be abandoned.

Naturally there’s some debate as to how far off that day is. NASA officially plans to support the Station until at least 2024, and an extension to 2028 or 2030 is considered very likely. Political tensions have made it difficult to get a similar commitment out of the Russian space agency, Roscosmos, but its expected they’ll continue crewing and maintaining their segment as long as NASA does the same. Afterwards, it’s possible Roscosmos will attempt to salvage some of their modules from the ISS so they can be used on a future station.

This close to retirement, any new ISS modules would need to be designed and launched on an exceptionally short timescale. With NASA’s efforts and budget currently focused on the Moon and beyond, the agency has recently turned to private industry for proposals on how they can get the most out of the time that’s left. Unfortunately several of the companies that were in the running to develop commercial Station modules have since backed out, but there’s at least one partner that still seems intent on following through: Axiom.

With management made up of former astronauts and space professionals, including NASA’s former ISS Manager Michael Suffredini and Administrator Charles Bolden, the company boasts a better than average understanding of what it takes to succeed in low Earth orbit. About a month ago, this operational experience helped secure Axiom’s selection by NASA to develop a new habitable module for the US side of the Station by 2024.

While the agreement technically only covers a single module, Axiom hasn’t been shy about their plans going forward. Once that first module is installed and operational, they plan on getting NASA approval to launch several new modules branching off of it. Ultimately, they hope that their “wing” of the International Space Station can be detached and become its own independent commercial station by the end of the decade.
