Two days after a successful launch in California, SpaceX shot down another Falcon 9 rocket from Cape Canaveral on Wednesday. This carried a Dragon cargo ship, which was loaded with 5,660 pounds of equipment and supplies for the International Space Station ISS. 19659004] An attempt to regain the first stage of the amplifier, however, failed as the brake booster quickly tipped over its long axis during the last descent and tilted about its longitudinal axis. As a result, the missile landed far out of the finish and landed east of the launch pad for a gentle, upright "landing" in the Atlantic.

The rocket then toppled, splattered horizontally, and remained intact. SpaceX founder Elon Musk has tweeted that the hydraulic problem affected the movement of the rocket's four "lattice fins", which are used to control and maintain the orientation when the booster first drops the tail to the ground.

"Pump is single string", Musk tweeted, which means the system has no backup. "Some landing systems are not redundant because landings are considered critical to soil security but are not critical to the mission. Given this event, we will probably add a reserve pump and lines. "

A few minutes later he tweeted a video taken by a camera aboard the rocket has been.

"Engines stabilized the rocket just in time and allowed an intact landing in the water! Ships on the way to rescue Falcon, "he said.

It was SpaceX's sixth landing damage and the first since June 2016, which ended a series of 27 successful recoveries. The company's overall record is 32 successful recoveries: 11 at Cape Canaveral Air Force Station, one at Vandenberg Air Force Base in California, and 20 at offshore drone ships.

The new "Block 5" Falcon 9 stages are designed to fly dozens of times with minimal remediation between launches, a key element to the company's efforts to reduce launch costs by restoring and re-flying the recovered stages.

The stage started on Monday from California made its third flight, a first for SpaceX. But the rocket launched from Cape Canaveral on Wednesday was brand new. It is still unclear what went wrong with the free-end fin, or if the mishap will cause the Air Force to rethink SpaceX's permission to land at the Air Force Station.

The land system is, however, equipped with the safety of personnel and ground facilities mind. The missile's guidance system initially targets a "crash point" off the coast and only moves the target ashore during a final missile launch and only after ensuring that all systems are functioning properly.
