STATUS REPORT: ELV-052711

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 Aquarius/SAC-D spacecraft was moved on May 20 from the payload processing facility on south Vandenberg to NASA's Space Launch Complex 2 on north Vandenberg and hoisted atop the Delta II rocket The mechanical and electrical connections are complete The Flight Program Verification, an integrated electrical test involving the Delta II working together with the Aquarius/SAC-D spacecraft, was successfully completed on May 25 Installation of the payload fairing around the satellite is scheduled for May 28

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

Spacecraft: Juno Launch Vehicle: Atlas V-551 Launch Site: Cape Canaveral Air Force Station, Fla Launch Pad: Space Launch Complex 41 Launch Date: Aug 5, 2011 Launch Time: 11:40 a m EDT

Solar array No 1 with its associated magnetometer boom was installed May 21 A deployment test was conducted on May 23, and a solar array illumination test also was performed On May 24, a magnetometer functional test was done The solar arrays now are being stowed for flight

The Atlas V booster stage arrived by Antonov cargo aircraft at the Skid Strip on Cape Canaveral Air Force Station on the afternoon of May 23 The following morning it was offloaded and transported to the Atlas Spaceflight Operations Center (ASOC) to begin processing The Centaur upper stage arrived on May 25 and also was taken to the ASOC the next day Later at the launch pad, the Atlas V-551 configuration for Juno will have five solid rocket boosters attached

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 7920 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

GRAIL arrived at the Shuttle Landing Facility by Air Force C-17 cargo plane on May 20 from the Lockheed Martin plant in Denver, Colo After offloading, it was transported to the Astrotech payload processing facility located near Kennedy Space Center The pair of spacecraft was then placed on individual test stands End-to-end communications system testing now is under way with the Deep Space Network Solar array inspections now also are occurring

At NASA's Space Launch Complex 17B, with the Delta II fully stacked on the launch pad, prelaunch testing of the rocket began on May 20

GRAIL's primary science objectives will be to determine the structure of the lunar interior, from crust to core, and to advance understanding of the thermal evolution of the moon

Spacecraft: Mars Science Laboratory (Curiosity) Launch Vehicle: Atlas V-541 Launch Site: Cape Canaveral Air Force Station, Fla Launch Pad: Space Launch Complex 41 Launch Date: Nov 25, 2011 Launch Time: 10:21 a m EST

At the Payload Hazardous Servicing Facility at KSC, installation of the solar arrays on the cruise stage is under way, and mating of the heat shield to the back shell also is scheduled this week

The Atlas V for the Mars Science Laboratory will arrive this summer The Atlas V-541 configuration being used for Mars Science Laboratory will have four solid rocket boosters attached

The rover's 10 science instruments will search for signs of life, including methane, and help determine if the gas is from a biological or geological source The unique rover will use a laser to look inside rocks and release the gasses so that its spectrometer can analyze and send the data back to Earth
