Vandenberg Air Force Base, California - The launch of NASA’s Orbiting Carbon Observatory-2 mission (OCO-2) at Vandenberg Air Force Base in California is scheduled for Tuesday, July 1. Liftoff from Space Launch Complex 2 aboard a United Launch Alliance Delta II rocket is targeted for 5:56 a.m. EDT (2:56 a.m. PDT) at the opening of a 30-second launch window.
OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural “sinks” that absorb carbon dioxide and help control its buildup.
The OCO-2 and Delta II News Center at the NASA Vandenberg Resident Office will open Thursday, June 26. To speak with a NASA communications specialist, call 805-605-3051 beginning at that time. A recorded launch status report also will be available by dialing 805-734-2693.
A prelaunch news conference and mission briefing will be held from 7-9 p.m. EDT (4-6 p.m. PDT) Sunday, June 29 in the NASA Vandenberg Resident Office. The briefings will be carried live on NASA Television and streamed on NASA.gov with question-and-answer capability available from other NASA field centers. Media also can post questions via Twitter by using the hashtag #AskNASA during the briefings.
On launch day, NASA TV coverage and countdown commentary will begin at 3:45 a.m. EDT (12:45 a.m. PDT). Spacecraft separation from the rocket occurs 56 minutes 15 seconds after launch. A post-launch news conference with OCO-2 mission officials will be held approximately two-and-a-half hours after launch.
Live countdown coverage also will be available online. Launch updates will begin on NASA’s launch blog at 3:45 a.m. EDT (12:45 a.m. PDT). Coverage features real-time updates of countdown milestones, as well as streaming video clips highlighting launch preparations and liftoff. To view the launch blog, visit:
