From hopping/tumbling robots to gecko-inspired adhesives, a variety of technologies have been chosen by NASA for flight on commercial reusable launch vehicles and a commercial parabolic aircraft. The selections were made through NASA's Flight Opportunities Program. The program gives these 13 space technology payloads, including four from NASA's Jet Propulsion Laboratory, Pasadena, California, a chance to be tested before they are used in the harsh environment of space.

Including this latest selection, there have been 138 technologies selected for test flights facilitated by the Flight Opportunities Program of NASA's Space Technology Mission Directorate.

Parabolic aircraft flights will allow 11 of the new payloads to experience brief periods of weightlessness. The other two projects will fly on suborbital reusable launch vehicle test flights. The flights are expected to take place in 2014 and 2015.

The selected proposals requested flights on Zero-G Corporation's Boeing 727 parabolic flight aircraft, UP Aerospace's Space-Loft rocket and Masten Space Systems' Xombie vertical takeoff/vertical landing rocket.

Three of the JPL-led payloads will fly on the parabolic aircraft and one will go up on the suborbital reusable launch vehicle.

NASA manages the Flight Opportunities manifest, matching payloads with flights, and will pay for payload integration and the flight costs for the selected payloads. No funds are provided for the development of these payloads.
