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.
Tracking Falcon's Landing

During the landing on Wednesday, the flight computer recognized the Problem with the fins and never moved the impact point ashore during the last engine fire.
"The key point here is that we have a safety feature on board that ensures that the vehicle does not go ashore when everything is OK, and that worked perfectly," said Hans Koenisgman, Vice President of SpacerX, to reporters , "The vehicle kept away from anything where it could pose the least danger to the population or property."
"Public safety was well protected here," he added. "As much as we are disappointed with this landing or landing in the water, it shows that the system can recover from certain malfunctions overall."
The mission started at 1:16 pm. EST (GMT-5), when the nine Merlin 1C engines of the Falcon 9 were detonated with a roar and fiery exhaust current, quickly pushing the 230 foot booster off the Cape Canaveral Air Force Station launch complex 40.
The launch was delayed by one day, as there was time to exchange moldy food bars in a habitat containing 40 rodents that were sent to the station for medical research. But it was clear that Wednesday was sailed and the countdown to zero without interruptions demolished.
At the time of takeoff, the spacecraft flew 250 miles over the Indian Ocean south of Australia, but the plane of its orbit flew over the Cape Canaveral Air Force Station as the earth revolved beneath it. The Falcon 9 climbed directly northeast into this orbital plane to facilitate the scheduled rendezvous.
The first-stage engines stopped and the lower part of the rocket dropped off two minutes and 23 seconds after launch. The single engine driving the second stage then ignited for a six minute 18 second burn to complete its orbit.
The first stage turned and started three engines to reverse the course and return to Florida. Another fire broke off four minutes later and slowed the stage for descent into the thick, lower atmosphere.
Long distance tracking cameras provided spectacular views as the stage first fell towards Cape Canaveral. But the television views of a rocket-mounted camera suddenly turned, spinning about its long axis.
The mid-engine of the rocket launched as usual at the landing, and the landing legs of the booster were set up at a low altitude as in a normal landing. Interestingly enough, the use of the landing legs seems to have slowed down the rocket's rotation just before it hit the ocean.
The landing was unsuccessful, but the main objective of Wednesday's mission was to put the Dragon cargo ship in the proper orbit. And that's exactly what the Falcon 9 did.
If all goes well, the spaceship will reach the station on Saturday morning, move forward at a distance of about 30 feet, and then stand, while station commander Alexander Gerst will operate the lab's robotic arm fixing.
Johnson Space Center air traffic controllers in Houston will then take charge of the line and operate the arm remotely to attract the kite for docking at the station's grounded port on the station's front harmonic module. 19659004] The onboard scientific equipment includes an experiment to test refueling techniques for robotic spacecraft with ultracold cryogenic propellants. Another tool that uses laser beams to measure tree heights to determine the effects of deforestation on carbon dioxide processing, and another for the development of wound dressings that improve drug delivery.
A further experiment investigates the development of retinal implants intended to restore sight to patients with age-related vision. Macular degeneration and retinitis pigmentosa. The Galaxy Space Station Challenge's Marvel Guardians sponsored student experiments to develop a UV-activated dental adhesive that could help astronauts travel longer, and is testing a fog-based irrigation system for space-grown plants.
With the kite in hand, the station crew will focus their attention on a planned spacewalk next Tuesday. Cosmonauts Sergey Prokopyev and Oleg Kononenko inspect the Soyuz MS-09 / 55S ferry, which brought Gerst, Prokopyev and Serena Auñón-Chancellor into orbit on June 6. Kononenko met on Monday together with Canadian astronaut David Saint-Jacques and NASA astronaut Anne McClain at the station.
By the end of August, sensors detected a small pressure drop in the station's air supply due to a leak in the upper living room module of the Soyuz MS-09 vehicle. An inspection revealed that it was a small hole drilled in an inner panel.
Prokopyev sealed the hole with an epoxy-impregnated cloth and stuffed the leak. Russian engineers ordered the spacewalk next week to examine the exterior of the Soyuz to look for signs of damage that might be related to the hole found inside the spacecraft.
The hole seemed to be the result of a deliberate act of a person Presumably before the start the Russians did not draw any conclusions.
In any case, the habitation module is discarded before entering the atmosphere and the problem is not considered a security threat if Gerst, Prokopyev and Auñón-Chancellor return to Earth on December 20.
