Falcon 9 missile completes static fire test to launch Monday Wednesday – Spaceflight Now

A week after SpaceX's new crew capsule testing, SpaceX, SpaceX successfully completed its next Falcon 9 launcher on Saturday morning at Canaveral Cape, preparing for a predawn liftoff Wednesday with several tons of food, supplies and experiments at the International Space Station.

Falcon 9 missile without its Dragon cargo capsule fired nine Merlin 1D first-stage engines on Saturday at 10am. 10:00 EDT (1400 GMT) sending an exhaust hose in the air because full throttle was forced on petrol powered power stations, generating 1.7 million pounds of thrust.

SpaceX confirmed good tests on Twitter soon after the fire.

During the test, which lasted for several seconds, Falcon 9 was fixed on the ground. SpaceX will lower the Falcon 9 rocket at the Complex 40 launch pad and return it to a nearby hangar to be attached to the Dragon spacecraft used after the previous trip to the space station.

Falcon 9 and the return next week will return to the feed, preparing for the lift on Wednesday, May 1, at. 03.59 EDT (0759 GMT), about the time the Earth's rotation brings a pallet to the orbital plane of the space station.

SpaceX plans to unload Falcon 9 first stage on a drone ship in the Atlantic Ocean about 17 miles (28 kilometers) southeast of the launch pad or east of Canaveral Cape east.

SpaceX Landing Zone 1, former Atlas launcher at Canaveral Air Force Station, was at the Crew Dragon spacecraft on April 20 during a spot test. Investigators and ground teams protect the site after the accident and gather evidence to help identify the cause of failure, which led to a major failure of the commercial crew capsule program developed by SpaceX and NASA.

The accident caused SpaceX to move rocket launches to the next Falcon 9 launch from a land-based offshore drone ship. The resupply mission to the space station does not require all of the Falcon 9 lifting capacity, leaving enough fuel in the first phase to return and return to the Canaveral Cape, so the drone ship will be positioned directly on the shore rather than the most typical distance of several hundred miles.

NASA and SpaceX officials appreciate whether members of NASA's Aerospace Safety Advisory Panel believe that the incident last weekend could be a source of concern for the next Dragon Order Mission. But the Dragon cargo ship is very different from the crew crowd, and the April 20 accident occurred when the SuperDraco abortion engine of the crew capsule was tested, which will not be used for the Dragon spacecraft being picked up next week.

SpaceX continues to prepare for Wednesday's launch, but the crew crowd accident could once again be discussed by senior executives preparing a preparedness report on Tuesday.

Prior to that, the Falcon 9 engine test took place on Tuesday when the mission was canceled. But static fire was delayed until Saturday for uncertain reasons – SpaceX usually does not discuss the pre-start heat test before they finish – forcing one day to delay start-up on Wednesday.

The US Air Force's 45th Annual Quarter is forecast to predict a 80% probability of favorable weather conditions on Wednesday.

Assuming that Falcon 9 will rise on Wednesday, Dragon's delivery ship must reach the space station early Saturday. The astronauts will capture the Dragon freight carrier using an orbital laboratory Canadian construction robot, then move the delivery vessel to the mooring port to stay for about one month.

While astronauts distribute food, food and biological experiments in the dragon's compartment, robotic hands outside the station will get a couple of tool kits that will be installed on science decks outside the complex.

One of the experiments developed by NASA's Jet Propulsion Laboratory will measure the amount of carbon dioxide in the Earth's atmosphere during a three-year mission. Scientists want to expand the space-related carbon dioxide record that began in 2014 with the NASA Orbital Carbon Observatory satellite mission that has gone beyond design time.

Another external unit, managed by the US Military Space Test Program, in the management of Dragon, is conducting several studies, including a new x-ray experiment developed by NASA and Naval Research Laboratory. According to scientists, X-ray signals could provide a new way of communicating deeply with space probes or hypersonic missiles.

Wednesday's opening will be SpaceX's fifth mission a year and the fifth launch from Canaveral Cape so far in 2019.
