EXPENDABLE LAUNCH VEHICLE STATUS REPORT

Spacecraft: Aquarius Launch Vehicle: Delta II 7320 Launch Site: Vandenberg Air Force Base, Calif Launch Pad: Space Launch Complex 2 Launch Date: June 9, 2011 Launch Window: 7:20:13 - 7:25:13 a m PDT Altitude/Inclination: 408 2 statute miles/98 degrees

At Vandenberg Air Force Base, the solar array for the Aquarius/SAC-D spacecraft was installed on April 28, and a deployment test was successfully conducted on April 29 Loading the spacecraft with its attitude control propellant is scheduled for May 10

At NASA's Space Launch Complex 2, the Delta II first stage will be loaded with liquid oxygen and a countdown test conducted on May 11 This will be followed on May 12 with a Simulated Flight test This is an electrical and mechanical test of the launch vehicle's systems that will be exercised in the same sequence as they will operate during the actual powered flight

The Aquarius/SAC-D mission is a collaboration between NASA and Argentina's space agency with participation by Brazil, Canada, France and Italy NASA's Launch Services Program at the Kennedy Space Center in Florida is managing the launch United Launch Alliance of Denver, Colo , is NASA's launch service provider of the Delta II 7320

The Plasma Waves Instrument (WAVES) has been installed, and a deployment test successfully was conducted on May 1 Communications system end-to-end testing with the Deep Space Network and its associated tracking stations was completed this week The work to install the three solar arrays and the associated magnetometer boom will begin on May 18

The solar-powered Juno spacecraft will orbit Jupiter's poles 33 times to find out more about the gas giant's origins, structure, atmosphere and magnetosphere

Spacecraft: GRAIL (Gravity Recovery And Interior Laboratory) Launch Vehicle: Delta II Heavy Launch Site: Cape Canaveral Air Force Station, Fla Launch Pad: Space Launch Complex 17B Launch Date: Sept 8, 2011 Launch Time: 8:37:06 a m EDT and 9:16:12 a m EDT
