CAPE CANAVERAL, Fla. – Answering questions from the media at a press conference held at NASA's Kennedy Space Center in Florida are (second from left) Associate Administrator for NASA's Space Operations Directorate William Gerstenmaier, Canadian Space Agency President Steve MacLean, Japan Aerospace Exploration Agency Executive Director of Human Space Systems and Utilization Kuniaki Shiraki, Shuttle Launch Integration Manager Mike Moses and STS-127 Shuttle Launch Director Pete Nickolenko. At far left is moderator John Yembrick from NASA Public Affairs. The conference followed the successful launch of space shuttle Endeavour on the STS-127 mission. This was the sixth launch attempt for the STS-127 mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues. Endeavour will deliver the Japanese Experiment Module's Exposed Facility and the Experiment Logistics Module-Exposed Section in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station.

VANDENBERG AIR FORCE BASE, Calif. – Ken Jucks, Orbiting Carbon Observatory-2 project executive at NASA Headquarters, participates in a mission science briefing at Vandenberg Air Force Base in California prior to the launch of the observatory, or OCO-2. Launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 is scheduled for 5:56 a.m. EDT on July 1. 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. To learn more about OCO-2, visit http://www.nasa.gov/oco2.

From left are George Diller, briefing moderator for NASA; Alan Thirkettle, International Space Station Program Manager for ESA, the European Space Agency; and Mauro Piermaria, ESPERIA mission manager for ASI, the Italian Space Agency. The STS-120 mission will be the 23rd shuttle flight to the International Space Station, delivering the Italian-built U.S. Node 2, called Harmony. The seven-member crew includes ESA astronaut Paolo Nespoli from Italy. The 14-day mission includes five spacewalks -- four by shuttle crew members and one by the station's Expedition 16 crew -- to install Harmony and move the P6 solar arrays to their permanent position and deploy them. Launch aboard space shuttle Discovery is planned for 11:38 a.m. EDT Oct. 23, and Discovery is scheduled to complete its mission and return home on Nov. 6. Photo credit: NASA/George Shelton

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, a press conference following the successful launch of space shuttle Atlantis on the STS-125 mission featured (from left) Associate Administrator for NASA's Space Operations Directorate William Gerstenmaier, Associate Administrator for NASA's Science Mission Directorate Ed Weiler, Launch Integration Manager Mike Moses and Shuttle Launch Director Mike Leinbach. Atlantis will rendezvous with NASA's Hubble Space Telescope. Liftoff was on time at 2:01 p.m. EDT. Atlantis' 11-day flight will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments that will expand Hubble's capabilities and extend its operational lifespan through at least 2014. The payload includes a Wide Field Camera 3, Fine Guidance Sensor and the Cosmic Origins Spectrograph. Photo credit: NASA/Jim Grossmann

This was the sixth launch attempt for the STS-127 mission. The launch was scrubbed on June 13 and June 17 when a hydrogen gas leak occurred during tanking due to a misaligned Ground Umbilical Carrier Plate. The mission was postponed July 11, 12 and 13 due to weather conditions near the Shuttle Landing Facility at Kennedy that violated rules for launching, and lightning issues. Endeavour will deliver the Japanese Experiment Module's Exposed Facility and the Experiment Logistics Module-Exposed Section in the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station.
