Caltech Cargo Launched to Space Station

When the SpaceX-3 cargo resupply mission launched to the International Space Station April 18, an experiment designed by the California Institute of Technology (Caltech) , was among the cargo headed to space.

The experiment, Crystallization of Huntingtin Exon 1 Using Microgravity (CASIS PCG HDPCG-1), investigates the crystallization of huntingtin, a protein associated with Huntington’s disease that has evaded crystallization for more than a decade. Crystallization is crucial for the development of new drugs to treat this degenerative brain disorder, which is caused by an inherited mutation in the huntingtin gene.

SpaceX-3 is NASA’s third contracted resupply mission to the space station by U.S. company SpaceX of Hawthorne, Calif. SpaceX’s Dragon spacecraft launched atop the company’s Falcon rocket from the Cape Canaveral Air Force Station in Florida at 3:25 p.m. EDT.

SpaceX developed its Dragon capsule, the only cargo spacecraft currently servicing the space station with the capability to return cargo back to Earth, with NASA and now successfully has completed three missions to the orbiting outpost. Expedition 39 crew members captured the SpaceX-3 Dragon using the station’s robotic arm at 10:06 a.m. EDT, Sunday, April 20. The capsule is scheduled to remain attached to the station until May 18. It then will return to Earth and splash down in the Pacific Ocean, off the coast of California. It will return samples from scientific investigations currently underway aboard the space station.

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 had continuous human occupation since November 2000. In that time, it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA’s next great leap in exploration, including future missions to an asteroid and Mars.
