Mission: |
Dragon CRS-3, also designated SpaceX-3, is
a 10-ton automated cargo spaceship that delivers 2.3 tons of equipment
to the International Space Station under contract to NASA, including 715
kg of science and research gear, 475 kg of crew provisions, 204 kg of vehicle
hardware and 123 kg of spacewalk tools. Cargoes includes a new spacesuit,
spare parts and science equipment, a garden to demonstrate vegetable growth
in microgravity, and a set of high-tech legs for Robonaut 2, which will
provide the humanoid robot torso already aboard the station the mobility
it needs to help with regular and repetitive tasks inside the space station.
The Dragon spacecraft
sports several upgrades over its predecessors, nearly quadrupling the ship's
capacity for powered cargo. The modifications include additional freezers
for biological samples and redesigned cargo racks to accommodate additional
payloads. The mission is also taking up research experiments in the Dragon's
unpressurized trunk for the first time. The passengers include a NASA optical
communications terminal (OPALS) to demonstrate high data-rate links between
the space station and the ground, along with a high-definition camera suite
(HDEV) to collect videos of Earth to be installed on the ISS with the help
of Dextre robot-arm.
Total mass of Dragon
CRS-3 at orbit insertion may be around 10,000 kg, larger than earlier missions,
but this is speculative since SpaceX do not released mass information.
This is the third commercial ISS resupply flight carried out by SpaceX
under a $1.6 billion contract with NASA calling for at least 12 cargo missions
to deliver some 20 tons of equipment and supplies.
On its way to the
ISS, the Falcon rocket jettisoned five small research satellites known
as CubeSats and that are to perform a variety of technology demonstrations.
The small satellites are part of NASA's Educational Launch of Nanosatellite,
or ElaNa, mission, and involved more than 120 students in their design,
development and construction.
Some 40 hours after
launch, Dragon arrived in the vicinity of the Station and was grapple by
Canadarm 2 on 20 April 2014 at 11h14 UT and docked to ISS’s Harmony.
The cargo craft remained attached until 18 May. It was then released
at 13h26 UT and splashed down in the Pacific Ocean, off the coast of Baja
California, at 19h05 UT.
As the only space
station resupply spacecraft designed to return to Earth intact, Dragon
carries down 1,616 kg of cargo, including science samples from human research,
biology and biotechnology studies, physical science investigations as well
as crew supplies, vehicle hardware and educational materials. In particular,
a spacesuit in need of repair was strapped inside the cargo craft, along
with water samples NASA says it needs to complete an investigation into
why an astronaut's helmet filled with water during a spacewalk in 2013. |
Notes: |
This was the first flight of a Falcon 9 with
experimental landing legs on the first stage. Stage 1 reignited during
descent after reaching probably around 120 km, and touched down vertically
on the ocean after demonstrating that it could maintain its orientation
during the return from space. |
