It is hard to tell from the images, but this week’s flight of the Falcon 9 rocket will likely be the final test flight of a Falcon 9 booster that SpaceX has built in Florida.
The rocket’s landing on the deck of the Space Station has been delayed by two weeks.
The company will have to replace the engines, which have been in service for two years.
The test flight was supposed to begin on June 3, but the company had to postpone the launch due to an issue with the rocket’s fuel system.
The SpaceX rocket has flown twice before, both on the Space Shuttle Endeavour missions in 2005 and 2007.
In 2008, it delivered the first commercial crew capsule to the space station, and in January of this year, SpaceX successfully delivered another spacecraft to the station.
On Tuesday, the company posted a video of the rocket and a rocket motor in flight, showing the booster powering the Dragon capsule to a landing in the Pacific Ocean.
The video, which was released by the National Oceanic and Atmospheric Administration (NOAA), showed the booster firing its first of three engines.
The Dragon capsule was carrying seven astronauts, including NASA astronaut Samantha Cristoforetti.
“This is a very exciting day for the astronauts of Dragon and all of the people who have been involved in this program,” NASA Administrator Charles Bolden said in a statement.
“As the nation’s first crewed spacecraft to orbit the Earth, Dragon is a vital part of NASA’s Journey to Mars.
Today marks another step toward our goal of returning to the Moon by the 2030s.”
The company’s launch window was also extended from the previous Thursday, when it was supposed in the middle of May to take the Dragon to the ISS.
The company has made several attempts to reach the station since 2007, with two failed attempts in 2012 and two in 2013.
The first attempt in 2012 landed in the ocean, with the second in March of that year in an attempt to get to the lunar surface.
The second attempt on May 18 failed, but SpaceX had planned to launch Dragon in a modified version of the company’s Dragon V2 rocket.
SpaceX also tested the Dragon spacecraft in May 2013, but both flights ended in failure.
NASA Administrator Charles F. Bolden addresses the media in Washington, DC, United States, on April 21, 2018.
President Donald Trump has said he will not renew NASA’s current contracts with SpaceX, and the space agency is struggling to find the money to keep the company afloat.
The White House has not released a schedule for the first mission to the orbiting outpost.
