In January, Elon Musk's SpaceX came close to a controlled landing of one of its rockets after a quick trip to space, before things took a fiery, explosive turn for the worst. Today, assuming all goes well and those X wing fins remain powered, it will try again. A launch scheduled for 4:33PM ET will send supplies to the International Space Station as a part of the CRS-6 mission, before the Falcon 9's first stage will try to land itself on a barge in the ocean. Creating rockets that can used again could help cut the cost of sending stuff to space, so there's a lot at stake beyond just looking cool in its Grasshopper demos. The launch will be webcast live starting at 4:15PM (the video feed is embedded after the break) although we'll have to wait a bit longer to see if the landing is successful.
