"And there go the arrays," NASA TV Commentator George Diller said as SMAP's three-panel solar array began to open. The spacecraft is power-positive. Deployment of the first CubeSat P-POD, FIREBIRD, is expected in about 45 minutes.
NASA's SMAP spacecraft is flying solo following a successful separation from the Delta II rocket. This is a 411-by-425-mile injection orbit. During the next few weeks, the spacecraft will make adjustments until it reaches its operational orbit of 426 miles. Once operational, the observatory will sweep above Earth in a near-polar orbit at an altitude …
SMAP will be released in two minutes.
Less than five minutes away from SMAP spacecraft separation.
The Delta II rocket's second-stage engine reignited for its second burn, which lasted the expected 12 seconds, and shut down on time.
Controllers are beginning to see the second stage go though some maneuvers to prepare for the second stage engine's second restart. It will burn for only about 12 seconds, and at that point there will be another five-minute coast phase before SMAP separation, expected at 10:18:51 a.m. EST.
SMAP is managed for NASA's Science Mission Directorate in Washington by the Jet Propulsion Laboratory in Pasadena, California, with instrument hardware and science contributions made by NASA's Goddard Space Flight Center in Greenbelt, Maryland. JPL built the spacecraft and is responsible for project management, system engineering, radar instrumentation, mission operations and the ground data system. …

The rocket's second stage engine shut down as scheduled nearly 11 minutes, marking the beginning of a 40-minute coast phase. That engine will reignite at 10:13:38 a.m. EST for a 12-second burn to place SMAP in its proper orbit.
