Boeing International Space Station Unpiloted Test Flight

The Boeing International Space Station unpiloted test aircraft has successfully completed a successful unmanned flight to the space station. The mission is part of NASA's Commercial Crew Program. The agency hopes to have two companies ferry astronauts to the station‚ decreasing its dependence on Russia. After the test flight‚ astronauts will again be strapped into the capsule. The capsule is designed to stay on the space station for about four or five days before it descends through a parachute descent. It will land in the desert in New Mexico.

A Boeing Starliner crew capsule was lifted into orbit by an Atlas 5 rocket Thursday. This is the third attempt of the company to get to the International Space Station in the last two-and-a half years. Starliners' December 2019 test flight was spoilt by. Software glitches that are embarrassing this prevented the station from docking and rendezvous autonomously. A failed reflight last august was called off when corrosion was discovered in valves of critical propulsion systems. Mission managers felt confident that the spacecraft was ready to go for another mission‚ and the United Launch Alliance Atlas 5 capsules roared into life at 6:54 P.M. EDT. They then departed from Cape Canaveral Space Force Station 41. The United Launch Alliance Atlas 5 rocket blasts off from Cape Canaveral Space Force Station.

The company hopes to launch the first crewed mission this year if the flight is successful.

The spacecraft performed a 45 second thruster firing‚ putting itself into orbit and preparing to rendezvous with NASA. Two of the two spacecraft's thrusters failed in the insertion burn. One After only one second‚ the other After 25 seconds. After the first two thrusters failed‚ the flight computer changed to the third one in the rocket pod. The burn went as planned. Four such starliner rocket pods are aft facing‚ also known as doghouses. Each one is fitted with OMAC thrusters to adjust the trajectory and three orbital maneuvering (OMAC)‚ thrusters. Officials stated that the Starliner would be capable of completing its mission‚ even if the engineers can't recover the jets. The capsule will dock with the laboratory complex around 7:10 pm on Friday. It will use a high-tech artificial visual system to find the station. There will also be 500 pounds worth of supplies for crew members and an instrumented mannequin named Rosie the Rocketeer that will gather environmental data during the mission. According to the flight plan‚ the capsule will spend five days at the station and then return to White Sands (New Mexico) on May 25‚ according to NASA. Boeing and NASA expect to send an astronaut crew aboard the station in a piloted test flight‚ provided there are no significant problems. NASA's test flight‚ which is an important step towards that goal since 2014‚ is crucial. NASA funded the commercial development of astronaut ferry boats to make up the loss from the retirement of the space shuttles in 2011. Boeing was awarded a contract worth $4.2 billion to build the Starliner‚ while SpaceX received a contract worth $2.6 billion to create the Crew Dragon. NASA's goals were to establish a U.S. space launch capability‚ and to end its post-shuttle dependence on Russian Soyuz spacecraft to transport astronauts to the station.

In early 2019‚ SpaceX followed with six station missions by crew and one private space tourism flight. Boeing had an even more difficult time‚ with its Starliner failing to reach the station on schedule during the 2019 test flight. Then it ran into problems such as valve corrosion that prevented a launch attempt in August. NASA management is keen to have the Starliner operational as quickly as possible in order to ensure that the company has access to space‚ even if there are technical difficulties. In an interview with CBS News‚ Mike Fincke‚ a veteran astronaut who has been trained to fly on a Starliner said that we can't keep all our eggs in the same basket. SpaceX could be experiencing some problems. They launch Falcon 9s all the time and this could cause delays in getting to the International Space Station. He said that having a second provider gives us an extra layer of security so that if one fails‚ the other can be used. Starliners' long-awaited flight began with the ground-shaking start-up of the Atlas 5s Russian-built RD-180 main motor. This generated 860‚200 pounds thrust and was followed by the ignition of two solid-fuel boosters that added another 697‚000 pounds. A 172-foot tall rocket lifted off majestically from a bright stream of fiery exhaust. It then arced to the northeast‚ climbing directly into orbit at the International Space Stations. Two minutes and twenty seconds later‚ the two strap-on boosters had been jettisoned. The rocket was lifted out of dense lower atmosphere and then the RD-180 came to a halt two minutes later. Centaur's second stage was powered by two Aerojet Rocketdyne RL10A engine. It then made its way to space.

However‚ an instrumented mannequin wearing a Boeing pressure suit‚ Rosie the Rocketeer‚ will collect data about accelerations‚ temperature and radiation throughout the flight. / Credit: Boeing After takeoff‚ the Starliner was allowed to fly by itself for 15 minutes. Boeing and ULA created a special trajectory for Starliner that allows it to return quickly to Earth in the event of major issues. The spacecraft needed to launch an orbit insertion rocket 16 minutes After it reached space. A software glitch prevented Starliners' maiden launch on December 19‚ 2019 from loading the proper launch time from the Atlas 5 flight computer. The orbit insertion burn didn't occur on schedule and‚ due to unrelated communication issues‚ flight controllers weren't able to regain control of the ship in time to push ahead with a rendezvous at the space station. After the Starliners landing‚ software issues were fixed along with other problems that emerged in post-flight reviews. Boeing decided to conduct a second flight at its expense. However‚ the aircraft was not ready for flying again until August last year. During the countdown launch controllers encountered stuck valves within the Starliners propulsion system. The problem was not solved by engineers and the capsule had to be removed from its Atlas 5 to return to the processing plant for repair. The problem was eventually attributed to moisture. This could have been caused by high humidity or torrential rains After rollout onto the pad. Thruster propellant chemically reacts with the water to cause corrosion. This corrosion stopped the valves opening at will. The valves of a new module's service module had to be replaced in order to make Thursday's launch possible. To purge and dry the thruster pods with gaseous nitrogen‚ sealings where the wiring entered the housings was done. The valves were also regularly closed and opened to check for performance. If the flight goes smoothly and Boeing successfully completes the piloted test flight‚ NASA management wants to alternate between SpaceX's one-year flight and Boeing's one-year flight.
