SpaceX is on track for a 30 April (Monday) launch of the Dragon spacecraft to the International Space Station, according to a detailed Flight Readiness Review (FRR) meeting between NASA and SpaceX officials met Monday (16 April) at Johnson Space Center in Houston. The mission is to fulfill both the Commercial Orbital Transportation Services (COTS) 2 and 3 requirements. Dragon is expected to deliver more than 1,200 pounds of supplies, if it is successful.

An FRR is standard part of all NASA pre-launch preparations. Bill Gerstenmaier, NASA’s associate administrator for Human Exploration and Operations said:

“Everything looks good heading to the April 30 launch date.”

NASA Television launch commentary from Cape Canaveral will begin at 8 AM Phoenix time (1500 UTC). There is a single instantaneous launch opportunity at 9:22 AM Phoenix time (1622 UTC).

The mission is composed of two sets of requirements. COTS 2 (see the slide above) deals with communicating and flying in the vicinity (but not too close, about 1.5 miles) of the International Space Station. The COTS 3 requirements concern the Dragon executing safety maneuvers (abort, retreat, hold), and eventually docking with the ISS when grappled by Canadarm.

Below are details of the Mission.
