A ULA Vulcan VC4L will loft Sierra Space's uncrewed Dream Chaser Tenacity on its first orbital flight. NASA and Sierra modified the CRS-2 contract so the debut will be a free-flying LEO demonstration rather than an ISS docking; Tenacity will fly with its Shooting Star cargo module and glide to a runway landing.
