SpaceX lands rocket on barge, but touchdown too heavy

SpaceX’s quest to reduce the cost of space travel through the reuse of rocket engines and other machinery hit a snag over the weekend when its first attempt at landing a rocket on a floating barge ended in failure.

Perhaps this news shouldn’t come as too much of a surprise, after all, SpaceX founder and CEO Elon Musk said last year that his team’s first attempt at landing the equivalent of “a 14-story building” on a 91 x 52-meter floating barge only had a 50 percent chance of succeeding.

The mission to deliver supplies to the International Space Station started well on Saturday morning with the successful launch of its Falcon 9 rocket from Cape Canaveral in Florida.

Once the cargo-laden capsule and rocket had separated, all eyes were on whether the booster would return to Earth and land damage free on the barge, otherwise known as the ‘drone spaceport ship,’ which was floating in wait off the east coast of Florida.

Alas, the landing didn’t work out in the way Musk and his team had hoped. While the rocket’s engine thrust managed to slow its descent, the impact was too heavy, with damage incurred by both the rocket and the barge.

Musk tweeted, “Rocket made it to the drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” adding that he was unable to get a “good landing/impact video” as the conditions were dark and foggy.

The SpaceX boss said that while Falcon 9’s grid fins worked “extremely well” from hypersonic velocity to subsonic, the heavy landing was caused by the vehicle running out of hydraulic fluid just before touchdown.

The failed landing means SpaceX’s plan to reuse the Falcon 9 rocket needs some work, but Musk and his team have never been under any illusions as to the size of the challenge. However, he’s pretty confident they can get it right in the 12 or so launches planned for this year, a success that could ultimately help to dramatically reduce the cost of space travel.

Problem in parachute test forced SpaceX to drop its mock spacecraft
Crew Dragon capsule

SpaceX and NASA are both busy preparing for the upcoming manned test of the Crew Dragon, SpaceX's capsule which will carry astronauts to the International Space Station (ISS) as part of NASA's Commercial Crew Program. However, the company ran into a problem while performing a parachute test on the capsule this week.

"On March 24, SpaceX lost a spacecraft-like device used to test the Crew Dragon Mark 3 parachute design," NASA wrote in an update from its Commercial Crew Program. "The test requires a helicopter to lift the device suspended underneath it to reach the needed test parameters. However, the pilot proactively dropped the device in an abundance of caution to protect the test crew as the test device became unstable underneath the helicopter. At the time of the release, the testing device was not armed, and a test of the parachute design was not performed."

SpaceX and NASA still set for historic May mission despite coronavirus
Crew Dragon capsule

Despite growing concerns over the coronavirus, SpaceX and NASA are still eyeing May 2020 for a mission that will mark the first launch of American astronauts aboard an American rocket and spacecraft since the final space shuttle mission in July 2011, ending U.S. reliance on Russia’s Soyuz program to get astronauts to and from space.

Bob Behnken and Doug Hurley are the two NASA astronauts set to travel to the International Space Station (ISS) aboard SpaceX’s Crew Dragon after launching from the Kennedy Space Center in Florida, according to a statement issued by NASA on Wednesday, March 18.

Today’s SpaceX Starlink launch was aborted due to engine power issue
60 Starlink satellites are launched aboard a Falcon 9 rocket on Monday, 17th February 2020.

SpaceX has been set to launch its sixth set of Starlink satellites today, but the launch was aborted at the last minute due to an engine power issue.

A Falcon 9 rocket carrying the satellites was set up on the launch pad at Launch Complex 39A at NASA’s Kennedy Space Center in Florida, but an error occurred during the launch preparation process. At T minus 40 seconds, the rocket was confirmed go for launch. But at the moment of ignition, the rocket failed to take off.
