NASA : Critical NASA Science Returns to Earth aboard SpaceX Dragon Spacecraft .- Crítico retorno de la NASA a la Tierra a bordo de la nave espacial SpaceX Dragón
Hola amigos : A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa sobre el crítico retorno de su Nave SpaceX's Dragon spacecraft.

SpaceX's Dragon spacecraft departed the space

SpaceX's Dragon cargo spacecraft splashed down in the Pacific Ocean about
7:44 p.m. EST Tuesday 259 miles southwest of Long Beach, California, with nearly
3,700 pounds of NASA cargo, science and first-of-its-kind technology
demonstration samples from the International Space Station.
The Dragon spacecraft will be taken by ship to Long Beach, where some cargo
will be removed and returned to NASA. Dragon will then be prepared for a return
trip to SpaceX's test facility in McGregor, Texas, for processing.
"The ability to resupply and return this critical research continues to be an
invaluable asset for the researchers here on Earth using the International Space
Station as their laboratory in orbit," said Kirt Costello, deputy chief
scientist for the International Space Station Program at NASA’s Johnson Space
Center in Houston.
Flight controllers in the Mission Control Center at Johnson robotically
positioned Dragon safely away from its docking port earlier Tuesday, where it
was released for its deorbit maneuver, sending it on its way to a
Among the returned investigations were printed parts and hardware from the
first technology demonstration of 3-D printing in space. The 3-D printer
demonstration used relatively low-temperature plastic feedstock on the space
station. The test phase ended with a printed ratchet wrench made with a design
file transmitted from Earth to the printer.
"Experiments like 3-D printing in space demonstrate important capabilities
that allow NASA and humanity to proceed farther on the journey to Mars,”
Costello said. “Other investigations such as those focused on protein crystal
growth take advantage of the unique microgravity environment and offer us new
avenues to investigate troubling diseases back on Earth."
Dragon also returned samples, hardware and data from several biology and
biotechnology studies performed on the station. The Advancing Membrane Protein
Crystallization by Using Microgravity investigation explored the production of
high-quality crystals of the cystic fibrosis protein and other closely related
proteins. Because many medically relevant proteins are difficult to crystalize
on Earth, researchers attempt to grow them in space to help determine their
shape and structure with the hope of improving drug therapies for cystic
fibrosis, a genetic disorder that causes severe damage to the lungs and
Samples from the Advanced Plant Experiments 03-1 will help scientists better
understand the effects of microgravity on the development of roots and cells on
plant seedlings. Researchers will conduct a detailed analysis of the returned
plant samples to determine the molecular and genetic mechanisms that control
plant development in microgravity. With this knowledge, scientists may be able
to improve agricultural and bioenergy research on Earth, leading to crops that
use resources more efficiently.
Dragon is the only space station resupply spacecraft able to return a
significant amount of cargo to Earth. The spacecraft lifted off atop a SpaceX
Falcon 9 rocket from Cape Canaveral Air Force Station in Florida on Jan. 10
carrying more than 5,000 pounds of supplies and elements to support 256
scientific investigations and arrived at the orbiting complex two days later on
Jan. 12. The mission was the fifth of at least 12 cargo resupply trips SpaceX
will make to the orbiting outpost through 2016 under NASA's Commercial Resupply
The International Space Station is a convergence of science, technology and
human innovation that demonstrates new technologies and makes research
breakthroughs not possible on Earth. The space station has been occupied
continuously since November 2000. In that time, more than 200 people and a
variety of international and commercial spacecraft have visited the orbiting
laboratory. The space station remains the springboard to NASA's next great leap
in exploration, including future missions to an asteroid and Mars.
