Elements of the next U.S. commercial cargo-delivery trip to the International Space Station are coming together at Kennedy Space Center for the planned March 10 liftoff.

One of five CubeSats deployed from the International Space Station last month is testing a steerable drag brake that could find use in future smallsats to return experiment samples to the ground from low Earth orbit, or on low-cost micro-probes to explore other planets.
