Good morning, and thanks for joining us for the countdown today. NASA's Orbiting Carbon Observatory-2 is sealed at the top of a United Launch Alliance Delta II rocket at Vandenberg Air Force Base, aiming for liftoff from Space Launch Complex 2 at 2:56 a.m. PDT, 5:56 a.m. EDT. Today's launch window extends for 30 seconds. …
Liftoff of the United Launch Alliance Delta II rocket with NASA's OCO-2 spacecraft is set for 2:56 a.m. PDT/5:56 a.m. EDT this morning from Space Launch Complex 2 at Vandenberg Air Force Base in California. Join us right here at 12:45 a.m. PDT/3:45 a.m. EDT for the latest from the countdown!
The launch of NASA's Orbiting Carbon Observatory-2 (OCO-2) aboard a United Launch Alliance Delta II rocket is scheduled for Wednesday, July 2 at 5:56 a.m. EDT (2:56 a.m. PDT) from Space Launch Complex 2 at Vandenberg Air Force Base in California. The launch team has completed troubleshooting of the launch pad water suppression system that …
Circadian Rhythms: FE-6 Gerst donned the Circadian Rhythms hardware to start a 36 hour data take. The main objective of the experiment is to get a better basic understanding of any alterations in circadian rhythms in humans during long-term space flights. This data will provide important insights into the adaptations of the human autonomic nervous …
The launch of a United Launch Alliance Delta II carrying NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite was scrubbed today due to an issue with the water suppression system that is used to flow water on the launch pad to dampen the acoustic energy during launch. Pending the outcome of troubleshooting, the launch is rescheduled for …
Today's launch attempt was scrubbed because of a failure in a Vandenberg Air Force Base Space Launch Complex 2 pad water system. The system provides sound suppression to dampen acoustic waves at liftoff and protects a launch pad flame duct. The countdown was halted at T-46 seconds. The Orbiting Carbon Observatory-2 (OCO-2) spacecraft is on …
NASA Launch Manager Tim Dunn has polled his launch team to confirm NASA is "go" for an on-time launch. The Delta II rocket and OCO-2 spacecraft are ready for flight and weather continues to cooperate.
This is a 10-minute hold. In a few minutes, Launch Director Don Malin of United Launch Alliance and NASA Launch Manager Tim Dunn will check with their teams to confirm that the rocket, spacecraft and all the necessary ground systems are ready for launch. The OCO-2 spacecraft is "go" to transfer to internal power.
The countdown has resumed. There's one more planned hold coming up at T-4 minutes.
The OCO-2 mission has special meaning to NASA's Launch Services Program, as we have dedicated it to one of our LSP teammates, Laurie Walls. Laurie began her career more than 30 years ago as a thermal engineer for McDonnell Douglas in Huntsville, Alabama, supporting NASA's Marshall Space Flight Center. She moved to Florida in 1985 …
