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 at VAFB 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 miles (705 kilometers) at an inclination of 98.2 degrees.
PRELAUNCH NEWS CONFERENCES
The prelaunch news conference and mission science briefing will be held from 4 to 6 p.m. PDT (7 to 9 p.m. EDT) on Sunday, June 29 at Vandenberg Air Force Base. The briefing will be carried live on NASA Television and streamed on NASA.gov.
