02.22.10 - Orbit circularization maneuver AMF #2B, using the ACS thrusters, was accomplished successfully tonight. The burn was 50 minutes long (as designed), and all hardware and software performed as expected. There is now quite a bit more data for the continuing fuel slosh analysis, and the perigee has been increased by approximately 1500 km.
02.21.10 - February 19, 2010 - The second Apogee Motor Firing (AMF #2) this evening was autonomously aborted after 30 seconds due to high system momentum. The Observatory is safe, the on-board system detected an unexpectedly high momentum, aborted the burn, and returned the Observatory to sun-pointing.
02.11.10 - NASA's Solar Dynamics Observatory, or SDO, lifted off Thursday from Cape Canaveral Air Force Station's Launch Complex 41 on a first-of-a-kind mission to reveal the sun's inner workings in unprecedented detail. The launch aboard an Atlas V rocket occurred at 10:23 a.m. EST.
02.10.10 - NASA has another day to interact with the public worldwide during Tweet-up events for the launch of the agency’s newest eye on the sun, the Solar Dynamics Observatory, or SDO. Launch is now scheduled for 10:23 EST, from Cape Canaveral Air Force Station, Fla.
01.22.10 - At Launch Complex 41, integrated testing of the Atlas and Centaur stages of the Atlas V for NASA's Solar Dynamics Observatory is continuing.
01.19.10 - NASA is scheduled to host a briefing at 1 p.m. EST, on Thursday, Jan. 21, to discuss the upcoming launch and science of an unprecedented mission to study the sun and its dynamic behavior.
01.19.10 - NASA's Solar Dynamics Observatory, or SDO, set to launch aboard a United Launch Alliance Atlas V rocket on Feb. 9, will be the focus of a media opportunity at 9 a.m. Thursday, Jan. 21, at the Astrotech Space Operations facility in Titusville, Fla.
01.19.10 - NASA is scheduled to host a briefing at 1 p.m. EST, on Thursday, Jan. 21, to discuss the upcoming launch and science of an unprecedented mission to study the sun and its dynamic behavior.
01.08.10 - The mating of the Centaur stage to the Atlas was delayed several days before the holiday break by high wind causing more time to be consumed than the contingency days which were available.
12.23.09 - The Centaur upper stage, the second stage of the Atlas V rocket scheduled to launch NASA's Solar Dynamics Observatory, was transported from the hangar at the Atlas Spaceflight Operations Center (ASOC), to the Vertical Integration Facility located at Launch Complex 41.
12.18.09 - At the Astrotech payload processing facility, Solar Dynamics Observatory (SDO) solar arrays were inspected and cleaned.
12.01.09 - At Space Launch Complex 2, work to install the Delta II payload fairing around NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft was completed as planned on Nov. 25.
11.24.09 - NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft was transported from the Astrotech payload processing facility to Space Launch Complex 2 on Nov. 20.
11.17.09 - The launch of NASA's Wide-field Infrared Survey Explorer (WISE) aboard the Delta II is being rescheduled by approximately two days. A launch date of Dec. 9 currently is under review.
10.30.09 - Build-up of the Delta II rocket at Space Launch Complex 2 was completed last week as planned.
