As of March 2011[update], Blue Origin had submitted the New Shepard reusable launch vehicle for use as an uncrewed rocket for NASA's suborbital reusable launch vehicle (sRLV) solicitation under NASA's Flight Opportunities Program. Blue Origin projects 100 km (62 mi) altitude in flights of approximately ten minutes duration, while carrying an 11.3 kg (25 lb) research payload.[2] By March 2016, Blue noted that they are "due to start flying unaccompanied scientific payloads later [in 2016]."[2]
