Last year, the company reached such a deal with Firefly Aerospace, who will supply Antares with a new first stage and engines. Since Russia's invasion of Ukraine, supply lines for the rocket's crucial components were cut off, forcing Northrop Grumman to seek alternative partners for manufacturing their launch vehicle. This was the final launch for the current version of the Antares rocket, which relies on Ukrainian-built first stages and Russian-produced RD-181 rocket engines. NG-19 is a resupply mission headed to the International Space Station. Thursday, August 3, 2023: Our staff was so blown away by this photo, we couldn't stop staring at it long enough to post it as yesterday's Image of the Day, so here it is today! This image shows the business end of Northrop Grumman's NG-19 Antares launch, and a fiery RD-181 rocket engine. A spectacular liftoff was the reward for each processing flow, and upon landing, the sequence began once again.NG-19 launched Tuesday, August 1, 2023. Finally, the completed launch vehicle and its mobile launcher platform rolled out to the launch pad atop a sturdy, slow-moving crawler-transporter. The shuttle then was towed to the nearby Vehicle Assembly Building, where it was joined to its tank and boosters. Once a shuttle was returned to its bay in the orbiter processing facility after landing, teams checked, refurbished or installed hardware for the flight ahead. Multiple vehicles could be in various stages of processing at any given time. To meet the rigorous demands of spaceflight, each vehicle element - the orbiter, external fuel tank and boosters - and all subsystems underwent meticulous maintenance and preparation before each flight. Because a returning shuttle orbiter was essentially an unpowered glider, there were no second chances - every touchdown had to be perfect. Missions typically lasted one to two weeks, concluding with an hourlong reentry descent through Earth's atmosphere and a precision landing. Of those missions, 78 ended with a Kennedy landing 54 concluded with a touchdown on the dry lake bed at Edwards Air Force Base in California and one landed at White Sands Space Harbor in New Mexico.Įach mission began with a thundering liftoff as the shuttle's twin solid rocket boosters ignited, pushing the vehicle with its crew and cargo beyond the bounds of gravity and into the hostile environment of space. Each one began at Kennedy's Launch Complex 39. › View larger image NASA's shuttle fleet - Columbia, Challenger, Discovery, Atlantis and Endeavour - flew a total of 135 missions.

Space shuttle Atlantis completed the program on July 21, 2011, wrapping up the STS-135 mission with a predawn touchdown on the same runway where Columbia first arrived more than 30 years earlier.
