L-1 Day – Forecast Remains 90 Percent ‘Go’

2015-1864With one day until launch of SpaceX’s seventh commercial resupply  mission, U.S. Air Force 45th Weather Squadron forecasters are predicting a 90 percent chance of favorable conditions for lift off. SpaceX’s Falcon 9 rocket and Dragon spacecraft are scheduled to launch at 10:21 a.m. EDT, Sunday, June 28, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Launch coverage on NASA television and the NASA Launch Blog will begin at 9 a.m.

The cargo includes the first of two International Docking Adapters, pictured, that will be connected to the space station to provide a place for Commercial Crew spacecraft carrying astronauts to dock to the orbiting laboratory.

Today NASA will host a panel discussion about the future of the International Space Station at 2 p.m. NASA Television will provide live coverage and streaming Internet coverage at http://www.nasa.gov/nasatv. Participants are:
Heidi Smith and John Weiler, students, Bell Middle School, Golden, Colorado, who have an investigation flying as part of the Center for the Advancement for Science in Space (CASIS) National Design Challenge
Bill Dowdell, International Space Station Program, NASA’s Kennedy Space Center
Lisa Colloredo, associate program manager, Commercial Crew Program, NASA’s Kennedy Space Center
Chris Ferguson, director of Crew and Mission Systems, Commercial Crew Division, The Boeing Company
Hans Koenigsmann, vice president of Mission Assurance, SpaceX

The Dragon spacecraft will be filled with more than 4,000 pounds of pressurized supplies and payloads, including critical materials for the science and research investigations that will occur during Expeditions 44 and 45. Science payloads will offer new insight to combustion in microgravity, perform the first space-based observations of meteors entering Earth’s atmosphere, continue solving potential crew health risks and make new strides toward being able to grow food in space. Research continues to support the twins study and one-year mission investigations with NASA astronaut Scott Kelly.

Posted on by .

16161219700_3e2dc339f6_oThe SpaceX Falcon 9 rocket passed a critical engine test today as preparations remain on track for Sunday’s launch, Hans Koenigsmann of SpaceX told reporters Friday. The static fire test at Space Launch Complex 40 at Cape Canaveral Air Force Station fired the nine engines for less than a second to confirm that the rocket is ready to lift a Dragon spacecraft loaded with more than two tons of cargo and experiments to the International Space Station.

Liftoff is scheduled for Sunday at 10:21 a.m. EDT. The weather forecast stands at 90 percent chance of acceptable conditions at launch time. For details into all aspects of the mission, read the SpaceX_NASA_CRS-7_PressKit.
