NASA’s OCO-2 Observatory Ready for Launch
The launch of NASA’s Orbiting Carbon Observatory-2 mission (OCO-2) at Vandenberg Air Force Base (VAFB) 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 2:56 a.m. PDT (5:56 a.m. EDT) 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 observatory will measure the global geographic distribution of these sources and sinks and study their changes over time.
The spacecraft’s final circular polar orbit will be 438 nautical miles (705 kilometers) at an inclination of 98.2 degrees.
News media desiring accreditation for the prelaunch and launch activities of OCO-2 should contact:
Tech Sgt. Vincent Mouzon
30th Space Wing Public Affairs Office
Vandenberg Air Force Base, CA 93437
Information required for U.S. media is full legal name, date of birth and media affiliation. A legal photo identification will be required upon arrival at Vandenberg. The date for foreign news media to apply for accreditation has passed.
PRELAUNCH NEWS CONFERENCE
Sunday, June 29: The prelaunch news conference and mission science briefing will be held from 4 to 6 p.m. PDT (7 to 9 p.m. EDT) in the second floor conference room of the NASA Vandenberg Resident Office, Building 840, at Vandenberg Air Force Base. The briefing 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.
Media desiring to cover the event should meet at the south gate of VAFB on California State Road 246 at 3:30 p.m. to be escorted by 30th Space Wing Public Affairs to the news conference.
Participants in the prelaunch news conference will be:
Betsy Edwards, OCO-2 Program Executive
Tim Dunn, NASA Launch Manager

MISSION SCIENCE BRIEFING
An OCO-2 Mission Science Briefing will be held immediately following the prelaunch news conference. Presenting the mission science objectives will be:
Ken Jucks, OCO-2 Program Scientist
David Crisp, OCO-2 Science Team Leader
Annmarie Eldering, OCO-2 Deputy Project Scientist
A post-launch news conference with OCO-2 mission officials also will be held at 5:30 a.m. PDT (8:30 a.m. EDT) on Tuesday, July 1, approximately 2.5 hours after launch.
Monday, June 30: Media desiring to establish sound-activated remote cameras at the launch pad should meet at the pass and identification building located at the Vandenberg main gate on California State Road 1 at 9:30 a.m. to be escorted to Space Launch Complex 2.
NEWS MEDIA LAUNCH PAD PHOTO OPPORTUNITY
Monday, June 30: There will be an opportunity for the media to photograph the Delta II with OCO-2 during rollback of the mobile service tower at the launch pad. Media should be at the pass and identification building at the Vandenberg main gate on California State Road 1 at 3 p.m. in preparation for going to Space Launch Complex 2. Photographers should be aware that first motion of tower rollback is targeted for 4 p.m. but does not always occur exactly as scheduled.
Those wishing to attend should confirm their participation with Tech. Sgt. Vincent Mouzon in the 30th Space Wing Public Affairs office at 805-606-3595.
LAUNCH DAY MEDIA COVERAGE
Tuesday, July 1: Media covering the OCO-2 launch aboard the Delta II rocket should meet at 1:45 a.m. at the Vandenberg main gate located on California State Road 1 to be escorted to the press viewing site. Press credentials and identification from a bona fide news organization will be required for access. A driver’s license alone will not be sufficient.
After launch, media will be escorted back to the main gate. Media interested in participating in the OCO-2 post-launch news conference will be escorted to NASA Building 840 on south Vandenberg. Observatory and mission officials will provide the spacecraft status and discuss its state of health. The event will begin at 5:30 a.m. PDT (8:30 a.m. EDT) and will be carried live on NASA Television.
