the ROME – All depends on a test. It took the countdown to the launch of the shuttle Crew, the Dragon of SpaceX, destined to return to the United States the capacity to carry men into space. Tomorrow, 18 January at 14 in italy is expected from the base of Cape Canaveral in Florida. It will be a test of interruption in flight without a crew and if you will show the ability of the Crew Dragon to leave the security of spacex Falcon 9 rocket in case of a failure during the launch, there will be a green light to the first flight with astronauts. Participate in the test, but without climbing aboard the shuttle, the two astronauts of the Nasa, Doug Hurley and Bob Behnken , assigned to the first mission of the test with the crew of Crew Dragon scheduled at the end of the year, wearing the space suits will simulate the stages of their preparation for the launch. The departure is scheduled from the historic complex 39A, from where they rode the shuttle to the Apollo and the Shuttle. The test provides that the spacex Falcon 9 rocket lights up its nine Merlin engines 1D and starts following a trajectory of standard cast to imitate a flight to the Space Station. When the Falcon 9 will be about 19 km of height, the Atlantic Ocean, and have reached the supersonic speed provided, approximately 84 seconds after take-off, turn off the engines to simulate the failure of the launch. At that point, eight engines SuperDraco of the shuttle Crew, the Dragon will turn to quickly push the capsule away from the top of the Falcon 9. While the rocket will fall in the ocean, the shuttle will turn off the engines SuperDraco, and turn on the engines smaller, opening the parachute and closing the mission with a dip in the ocean about 32 kilometers off the coast of Florida, where engineers at SpaceX and the u.s. air force the recover. The test takes place less than a year from the mission test of Crew Dragon, which in march 2019 was flown without a crew and was docked successfully to the international Space Station, and almost a month from the failure of the test without a crew capsule Starliner, Boeing just a few minutes from launch, is not entered in the projected orbit, skipping the docking of the Space Station.
