The company said Wednesday morning that a new target launch date has not yet been set. See updates at Live coverage: SpaceX launch on hold at Cape Canaveral – Spaceflight Now.
Blue Origin has posted that a problem in the ground support system that caused Tuesday’s scrub of a suborbital flight of a reusable New Shepard vehicle should be fixed in time for a launch on Friday. The New Shepard will carry nine NASA R&D experimental payloads that will take advantage of “about 4 minutes of high-quality microgravity” after the capsule separates from the booster and coasts up to and down from 100+ kilometers in altitude.
