The 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.

DRAGON DEBRISOn Sunday morning, a SpaceX Falcon 9 rocket lifted off from Cape Canaveral bound for the International Space Station. Two minutes and 19 seconds later, it exploded. The Dragon spacecraft on top of the rocket was carrying more than 4,000 pounds of food and supplies--suddenly turned to ash. A weather radar in Melbourne FL tracked the airborne debris:
"Figuring that the debris cloud would likely show up on Doppler, I pulled the NEXRAD data for the Melbourne radar," says Rob Matson, who created the graphic. "High altitude (21.5-km) debris first appears a little after 14:28 UT (10:28 am EDT), which was a little less than 5 minutes after the failure. This image is a composite of 29 sweeps over a period of about 12 minutes."
"I figure debris will starting washing ashore near Daytona in the next day or two," he adds.
