Liftoff of the SpaceX Falcon 9 rocket and Dragon spacecraft on a mission to deliver supplies to the International Space Station is scheduled for Monday, Aug. 14 at 12:31 p.m. EDT. This will be the company’s twelfth commercial resupply mission to the orbiting laboratory.

The latest launch weather forecast remains essentially the same, with a 70 percent chance of favorable conditions at liftoff. Primary weather concerns will be cumulus clouds and flight through precipitation, although the early afternoon launch time is promising, according to the forecast discussion provided by the U.S. Air Force 45th Weather Squadron.

NASA, SpaceX and other launch and mission officials will participate in televised briefings today. A prelaunch news conference is planned for 2 p.m., followed by the “What’s on Board” briefing at 3:30 p.m. Both will be broadcast on NASA TV — watch live at http://www.nasa.gov/ntv.

Join us tomorrow for live countdown coverage beginning at noon here on NASA’s Launch Blog and on NASA TV.

Weather Prediction: 70 Percent ‘Go’ for Monday Launch

Today’s “launch minus two days” weather forecast has been issued by meteorologists with the U.S. Air Force 45th Weather Squadron ahead of Monday’s planned liftoff of a SpaceX Falcon 9 rocket and Dragon spacecraft. The forecast continues to predict a 70 percent chance of favorable weather conditions. Primary concerns are cumulus clouds and the potential for precipitation in the flight path.

Liftoff is scheduled for 12:31 p.m. EDT from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. This will be SpaceX’s twelfth commercial resupply mission to the International Space Station.

On Sunday, NASA TV will broadcast a prelaunch news conference at 2 p.m., followed at 3:30 p.m. by the “What’s on Board” science, research and technology briefing. Watch live at http://www.nasa.gov/ntv.

Weather Forecast for Monday’s Planned Launch of SpaceX CRS-12

Meteorologists with the U.S. Air Force 45th Space Wing are predicting a 70 percent chance of favorable weather for liftoff of the SpaceX Falcon 9 rocket carrying a Dragon spacecraft. Launch of the company’s twelfth commercial resupply mission to the International Space Station is scheduled for Monday, Aug. 14 at 12:31 p.m. EDT from Launch Pad 39A at NASA’s Kennedy Space Center in Florida.

Rain and thunderstorms are expected today and through the weekend, especially in the afternoon – a familiar summer weather pattern for Florida’s Space Coast. Heading into Monday, cumulus clouds and flight through precipitation are forecasters’ primary launch weather concerns, but the early afternoon launch time is helpful.

Next SpaceX Flight to Resupply Space Station Targeted for Aug. 13

The next flight of a SpaceX Falcon 9 rocket to deliver cargo to the International Space Station now is targeted for Aug. 13 at approximately 12:56 p.m. EDT from Launch Pad 39A at NASA’s Kennedy Space Center in Florida.

This will be the company’s 12th commercial resupply mission to the orbiting laboratory. The Falcon 9 will send a SpaceX Dragon spacecraft filled with nearly 6,000 pounds of equipment, crew supplies and more than 250 science and research investigations.

Successful Launch for SpaceX CRS-11

The SpaceX Falcon 9 rocket lifted off at 5:07 p.m. EDT on Saturday, June 3, and the Dragon spacecraft has begun its journey to the International Space Station with an arrival scheduled for June 5. Dragon separated from Falcon 9 about 10 minutes after launch, and solar arrays successfully deployed shortly after separation from the second stage.

Before Dragon arrives at the space station, the Orbital ATK Cygnus cargo spacecraft will depart the station Sunday, June 4. Expedition 52 Flight Engineers Jack Fischer and Peggy Whitson of NASA will be at the controls of the Canadarm2 robotic arm to release Cygnus at 9:10 a.m. NASA TV coverage of the spacecraft’s departure will begin at 8:30 a.m.

Orbital ATK’s seventh cargo delivery flight to the station launched at 11:11 a.m. EDT Tuesday on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. This is the fourth flight of an enhanced Cygnus spacecraft, and the third using the Atlas V launch system.

The on-time launch marked the conclusion of a smooth countdown and the beginning of a three-day pursuit of the International Space Station, where resident crew members await the arrival of the Cygnus spacecraft and its 7,626 pounds of scientific research materials, crew supplies and station equipment. Cygnus is due to arrive at the station early Saturday morning, April 22.
