Two days after a successful launch from California, SpaceX dismissed another Falcon 9 rocket from Cape Canaveral Wednesday, the carrier of a Dragon cargo ship loaded with 5,660 pounds of equipment and accessories tied to the International Space Station. [19659004] However, an attempt to restore the first stage of the booster ceased to fail when a hydraulic system failure caused the booster to quickly spin and lean over its long axis during its final descent. As a result, the rocket landed well beyond the target and sat down to a mild, upright landing in the Atlantic just east of the launch site.

The rocket then shook over, sprinkled horizontally and remained intact. SpaceX founder Elon Musk tweeted that the hydraulic problem affected the movement of the rocket’s four titanium “rutfinnen”, which is used for steering and to maintain orientation as the booster drops tail first back to earth.

“Pump is single strand”, Musk tweeted, which means the system does not have a backup. “Some landing systems are not superfluous, as landing is considered to be land-critical, but not mission critical. In view of this event, we are likely to add a spare pump and lines.”

A few minutes later, he tweeted video captured by a camera aboard the rocket.

“Motors stabilized rocket spin just in time, allowing intact landing in water! Ships under route to save Falcon,” he said.

It was SpaceX’s sixth landing error and the first since June 2016, which ended a string of 27 successful rebounds. The company’s overall record stands for 32 successful recoveries: 11 at the Cape Canaveral Air Force Station, one at Vandenberg Air Force Base in California and 20 on Offshore Droneships.

The new “block 5” Falcon 9 phases are designed flights dozens of times with minimal refurbishment between launches, an important part of the company’s commitment to lower launch costs by recovering and recovering recovered steps.

The launch launched Monday from California made its third flight, a first for SpaceX. But the rocket launched Wednesday from Cape Canaveral was brand new. It is not yet clear what went wrong with the grid or if the accident will prompt the air force to reassess SpaceX’s clearance to land at the air force station.

However, the landing system is designed with security for personnel and landfills in mind. The government’s steering system initially targets an “offshore point” and stretches only the goal of the beach to the landing plate during a final rocket launch and only after verification that all systems are functioning properly.

During Wednesday’s landing, the airplane’s network problem was discovered and never moved landing point during the final engine firing.

“The important point here is that we have a safety feature on board that makes the vehicle not land until everything is ok and it worked perfectly,” said Hans Koenisgman, SpacerX Vice President of Construction and Air Safety, told reporters. “The vehicle is well kept away from all where it could be the least risk of population or property.”

“General security was well protected here,” he added. “As much as we are disappointed by this landing or landing in the water, shows that the system generally knows how to recover from certain errors. “

Mission commenced at 1:16. EST (GMT-5) when Falcon 9’s nine Merlin 1C engines were ignited with a breeze and a torrent of fire exhaust gas that quickly shoots up the 230-meter booster from startup complex 40 at Cape Canaveral Air Force Station.

Liftoff arrived one day late due to the time needed to replace moldy food rods in a residential building where 40 rodents were transported to the station for medical research. But it was clear to sail Wednesday and the countdown ticked to zero without interruption.

At the time of the liftoff, the space station flies 250 miles across the Indian Ocean south of Australia, but on The lane in its orbit swept across the Cape Canaveral Air Force Station as the earth rotated beneath it. Falken 9 climbed into the nostrils directly in the orbit to allow for the planned rendezvous.

The engines in the first stage were closed and the lower part of the rocket fell for two minutes and 23 seconds after the relay. The only engine running the second stage is then ignited for a six-minute 18-second burn to complete the climb to orbit.

The first leg was angry at the same time and started three engines to reverse the course and return to Florida. Another firing four minutes later, the stage slowed down for descent back to the thick lower atmosphere.

Long-track tracking cameras gave spectacular views as the scene drove the tail first towards Cape Canaveral. However, television views from a camera mounted on the rocket suddenly showed that it was rotated approximately if it was a long shaft.

The rocket’s center engine started as usual for landing, and the booster landing legs were placed at low altitude as they would in normal landing. Interestingly, landing leg expansion seems to have braked the rocket’s rotation just before impact in the ocean.

While landing failed, the primary goal of Wednesday’s mission was to deliver the freight cargo carrier to the right track. And Falcon 9 did just that.

If everything goes well, the spacecraft will reach the station on Saturday morning, pull up to within 30 meters and then stay while station manager Alexander Gerst, who drives the robot robot arm, locks on

Flight controllers at Johnson Space Center in Houston will take over at that time and maneuver the arm with the remote control to drag the dragon into the boat’s left port on the station’s forward Harmony module. 19659004] The scientific tools on board contain an experiment to test robotic tanker technologies using ultralight cryogenic fuels, another instrument that will use laser beams to measure tree heights globally to determine the effects of deforestation on carbon dioxide processing and another to develop wound dressings which improves drug delivery.

Another experiment will study the development of retinal implants intended to restore vision to patients with age-related macular degeneration and retinitis pigmentosa. Marvel Guardians of the Galaxy Space Station Challenge sponsors students experiments to develop a UV-activated dentallim that can help astronauts on long journeys and another testing of a dimming-based irrigation system for plants grown in space.

Station officials will draw attention to a planned spacecraft next Tuesday by cosmonauts Sergey Prokopyev and Oleg Kononenko for inspection of Soyuz MS-09 / 55S ferry vessels carrying Gerst, Prokopyev and Serena Auñón chancellors in a orbit on June 6 Kononenko arrived at the station on Monday with the Canadian astronaut David Saint-Jacques and the NASA astronaut Anne McClain.

At the end of August, the sensors detected a slight pressure drop in the station’s air supply which was detected as a leak in the upper housing module of the Soyuz MS-09 vehicle. An inspection revealed how it looked like a small hole drilled in an interior panel.

Prokopyev sealed the hole with epoxy wipes and stopped the leak. Russian engineers ordered the space promenade next week to inspect Soyuz’s exterior to look for any signs of damage that could be related to the gap in spacecraft.

While the hole appeared to be the result of deliberate action on someone’s part, probably before the launch, the Russians have not yet revealed any conclusions.

In any case, the module is discarded prior to atmospheric entry and the question is not considered to be a security threat when Gerst, Prokopyev and Auñón Chancellor return to Earth on December 20th.
