SpaceX's Falcon 9 rocket successfully executed a "static fire test" at around 1:30 p.m. EST (1830 GMT) today (Feb. 25), igniting its engines for a few seconds but staying earthbound at its launchpad at Florida's Cape Canaveral Air Force Station.
"During the static fire test today, SpaceX engineers ran through all countdown processes as though it were launch day," company officials said in a statement. "All nine engines fired at full power for two seconds, while the Falcon 9 was held down to the pad. SpaceX will now conduct a thorough review of all data and continue preparations for Friday's targeted launch."
The Falcon 9 is slated to blast SpaceX's robotic Dragon capsule toward the space station Friday on the company's second contracted cargo run for NASA. Dragon will carry about 1,200 pounds (544 kilograms) of supplies and scientific experiments to the orbiting lab, then return to Earth on March 25 with 2,300 pounds (1,043 kg) of experiment samples and equipment, NASA officials have said.
