WASHINGTON, DC — Three businessmen and a
former
NASA astronaut splashed down Monday off the Florida coast after spending
two weeks aboard the International Space Station in a landmark mission for the
commercial sector.

After a dizzying descent, a
SpaceX Dragon capsule
carrying the Axiom-1 gently floated down to the Atlantic Ocean near
Jacksonville at 1:06pm on four huge parachutes.
“Dragon Endeavor has returned home with the Axiom-1
Crew,” said an announcer, as a recovery vessel made its way to the capsule.
The spaceship was affectionately referred to as a
“toasted marshmallow” because of the scorch marks on its heat shield from
re-entering the atmosphere at 28,000km/h.
It marks the official end of the first fully-private
mission to the orbiting outpost — and a turning point in US space agency NASA’s
goal to commercialize the region of space called low Earth orbit.
“Welcome home,
Axiom-1!” tweeted NASA chief
Bill Nelson. “#Ax1 and all of the progress we’ve
seen in the commercial space sector wouldn’t be possible without NASA’s collaboration
with private industry.”
Axiom Space paid SpaceX for transport services and
NASA for use of the ISS, while charging the three tycoons a reported $55
million each for the privilege.
American real estate mogul Larry Connor, Canadian
financier Mark Pathy and Israeli impact investor Eytan Stibbe and veteran
Spanish-American astronaut Michael Lopez-Alegria had blasted off on April 8.
They were originally scheduled to spend only eight
days on the space station but bad weather forced repeated delays. In total, the
crew spent 17 days in orbit, 15 of those on the ISS.
Research, not tourism
Axiom had been keen to
stress its mission shouldn’t be considered tourism, unlike the recent,
attention-grabbing suborbital flights carried out by Blue Origin and Virgin
Galactic.
On board the ISS, which orbits 400km above sea
level, the quartet carried out research projects, including an MIT technology
demonstration of smart tiles that form a robotic swarm and self-assemble into
space architecture.
Another experiment involved using cancer stem cells
to grow mini tumors, then leveraging the accelerated aging environment of
microgravity to identify early changes in those tumors, to help improve
screening methods.
Pathy spent considerable time in the station’s
famous observation cupola, photographing Earth.
NASA has already given the green light, in
principle, to a second mission: Ax-2.
The departure of the Ax-1 crew left seven people on
the ISS: three Americans, a German and three Russians.
Monday’s sea landing of a manned SpaceX Dragon
capsule was the fifth to date.
SpaceX, owned by billionaire entrepreneur
Elon Musk,
is now regularly ferrying NASA astronauts to and from the space station.
Last year, Musk’s company launched another entirely
private mission, which orbited Earth for three days without linking up with the
ISS.
Axiom sees the voyages as the first steps of a
grander goal: to build its own private space station. The first module is due
to launch in 2024.
The plan is for the station to initially be attached
to the ISS, before eventually flying autonomously when the latter retires and
is deorbited sometime after 2030.
