When the SpaceX-3 cargo resupply mission launched to the International Space Station April 18, two experiments designed by researchers at the University of Florida in Gainesville were among the cargo headed to space.

One experiment, Biological Research in Canisters (BRIC), will focus on the growth and development of seedlings in microgravity. Seedlings will be preserved with a chemical fixative and returned to the ground for post-flight evaluation.

The other experiment, Molecular Biology of Plant Development in the Space Flight Environment (Characterizing Arabidopsis Root Attractions (CARA)), investigates the growth and development of Arabidopsis thaliana seedlings in microgravity environment, focusing on how a root knows which direction to grow in when gravity is absent. Plants are harvested in orbit, preserved with a chemical preservative and returned to the ground for post-flight evaluation.

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 at3:25 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 7:14 a.m. 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 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.

University of Florida Among NASA Cargo Launching to Space Station

NASA astronauts Steve Swanson and Rick Mastracchio will perform a 2.5 hour International Space Station spacewalk on Wednesday. The NASA live stream of the event begins at 8:30 a.m. EDT and the ISS Expedition 39 crew members will work to replace a faulty computer located on the exterior of the space station.

Swanson and Mastracchio will replace the unresponsive backup multiplexer-demultiplexer (MDM). NASA discovered the problem on April 11 and the backup MDM supports several robotic systems aboard the ISS. According to NASA, the MDM "provides redundancy for commanding the Mobile Transporter rail car on the truss of the station." The Mobile Transporter is part of the docking procedure that attaches spacecraft to the space station. For Swanson, it will be his fifth spacewalk and it will be the ninth for Mastracchio.

The recent SpaceX ISS commercial resupply mission could have been delayed by the unresponsive MDM but NASA went ahead with the launch and the spacecraft reached the ISS on Easter. There are 45 MDMs located throughout the space station and the backup MDM that failed has been attached to the ISS for more than 10 years.

According to NASA, the faulty backup MDM is located on the S0 truss, on top of the Destiny laboratory module. On Monday, the Expedition 39 crew spent the day unpacking the cargo from the Dragon spacecraft. The T-Cell Activation in Aging science experiment, which studies immune system depression in microgravity, was among the first items unloaded from the spacecraft.

On Tuesday, ISS Expedition 39 commander Koichi Wakata, from the Japan Aerospace Exploration Agency, met with Swanson and Mastracchio and discussed Wednesday's ISS spacewalk. Prior to the spacewalk, the ISS Progess 53 resupply spacecraft which is currently docked at the ISS will detach from the Zvezda service module, located on the Russian side of the space station. The cargo spacecraft will spend two days in space, traveling no farther than 311 miles away from the ISS, before reattaching on Friday, notes NASA.

The NASA International Space Station spacewalk is scheduled for 9:20 a.m. EDT and the live stream can be viewed below.

Two spacewalkers took on a quick computer repair job at the International Space Station on Wednesday, one of the crew's busiest days in orbit.

NASA astronauts Rick Mastracchio and Steve Swanson began the spacewalk at 9:56 a.m. ET, heading out to replace a backup computer box that failed less than two weeks ago. Japan's Koichi Wakata is playing a supporting role inside the station.

Meanwhile, their Russian crewmates Mikhail Tyurin, Alexander Skvortsov and Oleg Artemyev helped out with a previously planned test of an automated rendezvous system installed on a robotic Progress cargo ship. The Progress was undocked early Wednesday morning and took up a position about 300 miles (500 kilometers) from the station to begin two days of tests.

All this is going on while a freshly arrived SpaceX Dragon cargo ship is docked to a different port on the station.

NASA flight director Brian Smith said it's unusual to schedule an extravehicular activity, or EVA, amid so many other tasks.

"This isn't a long EVA," Smith told reporters during a pre-spacewalk briefing. "There are certainly EVAs that are more complicated than this one. However, the real trick has been to figure out how to put this EVA in the same week that we're doing the Dragon mission and we're doing the 53P Progress operations."

The spacewalk was choreographed quickly because NASA doesn't want to go without a backup for this particular computer box any longer than necessary. The box, known as a multiplexer-demultiplexer, plays a role in controlling critical systems on the space station, including the solar arrays, a robotic rail car and the external cooling system.

Flight Engineers Rick Mastracchio and Steve Swanson (partially obscured) install a new circuit board inside a spare multiplexer-demultiplexer aboard the International Space Station.

The primary computer box is working fine, and the crew is in no danger. But Smith said he and other mission planners were concerned about the "next worst-case failure" that is, the loss of the primary computer while the backup is out of commission.
