Any lesson or article in the
history of space travel would tell the reader that, while the Apollo rocket
program by NASA succeeded in putting man on the moon 16 times, it was also –
for the time – incredibly expensive due to how everything about the spacecraft
was one-use only. The American space agency found a solution in the Space
Shuttle system, but by now the shuttle fleet has been completely retired. At
this point NASA has been relying on private aerospace firms like SpaceX, which
has successfully deployed true reusable rocket engines and launch vehicles. Their
greatest highlight yet happened from May to this month, courtesy of the Crew
Dragon.
The Verge has it that the Crew Dragon Demo-2 mission by SpaceX to
demonstrate the reliable reusability of their Dragon 2 space rocket ended in
success this August 2, when the Crew Dragon capsule carrying a team of NASA
astronauts Douglas Hurley and Robert Behnken departed from the International
Space Station (ISS) and splashed down on the Gulf of Mexico offshore from
Pensacola, Florida this past Sunday. The crew had spent two months at the ISS after
they arrived there following the original launch of Crew Dragon Demo-2, May 30.

For Elon Musk’s aerospace
transportation company, the completion of Demo-2 proved that their Dragon 2
capsule’s manned variant (“Crew Dragon”) was a safe and reliable launch vehicle
for astronauts to get to space, primarily for docking with the ISS. Indeed,
after the Crew Dragon capsule, named Endeavor,
docked at the space station, its crew of Behnken and Hurley spent June and July
with the on-duty ISS Expedition 63 crew, helping with science experiments and
scheduled spacewalks. By August 1, the two astronauts were back in Endeavor with a load of scientific
cargo, just as the Crew Dragon undocked autonomously from its ISS berth to
prepare for re-entry to the Earth.
Besides the proving of the SpaceX
Dragon 2 system, the Demo-2 mission also logged some firsts for US space
travel. This was the first time a re-entry space capsule splashed down into the
sea since 1975 with the unnumbered Apollo capsule from the US-Soviet
Apollo-Soyuz Test Project. And rather than in the Pacific, Endeavor went down in the Gulf of Mexico, much closer to its launch
origin in Florida. With these out of the way, the second part of proving the
Crew Dragon’s capability will be done early next year.
At that time, the Endeavor Crew Dragon capsule will be
reused for the first time since its successful maiden flight, on a mission
designated Crew-2 carrying astronauts from NASA (two), Japan’s JAXA (1) and the
European Space Agency (ESA) (1).
