NASA Is Buying Commercial Suborbital Flights

NASA SpaceTech-REDDI-2015 Appendix F1: NASA Flight Opportunities Now Open
“The purpose of this Appendix is to provide funding for the testing or demonstration of crosscutting space technologies in relevant environments through flights on reusable suborbital launch vehicles. These flight tests should fit into an overall technology maturation plan as a bridge between laboratory testing and demonstration in Earth orbit or beyond. The proposer’s organization will purchase the proposed flight(s) on currently available U.S. commercial parabolic or suborbital reusable platforms of their choice.”
