The launch of NASA’s Orbiting Carbon Observatory-2 mission (OCO-2) at Vandenberg Air Force Base in Californiais 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 openThursday, 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.
Prelaunch and launch activities will take place June 29 through July 1. U.S. journalists should fax their accreditation requests on news organization letterhead to Tech Sgt.Vincent Mouzon, 30th Space Wing Public Affairs Office at Vandenberg, at 805-606-4571, or email vincent.mouzon@us.af.mil.

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.
