The countdown continues toward liftoff at 2:20 p.m. EST, 10 minutes from now. During this time, the Falcon 9’s engines will be chilled to condition them for launch, the flight computer will run its pre-launch checks and the rocket’s propellant tanks will be brought to flight pressure. Fueling of the Falcon 9 second stage began …

During SpaceX’s 26th commercial resupply services mission to the International Space Station for NASA, the Dragon spacecraft will deliver more than 7,700 pounds of supplies, equipment and several science investigations to the crew aboard the station, including the next pair of International Space Station Roll Out Solar Arrays (iROSAs), which will increase the power on …

The rocket awaiting launch this afternoon is the SpaceX Falcon 9, a two-stage vehicle topped by the company’s uncrewed Dragon spacecraft. The Falcon 9 first stage is powered by nine Merlin engines that ignite at T-0; its second stage has a single Merlin engine that takes over after separation of the first stage. Merlin engines …

On Nov. 23, the team in Mission Control Houston performed a change in electrical power routing to remove one of the eight International Space Station power channels from use. This procedure was performed in response to unexpected readings and intermittent tripping of the 1B power channel in the overnight hours. When the power channel tripped, …

Hello and happy Sunday afternoon from NASA’s Kennedy Space Center in Florida. The weather is looking much better today as NASA and SpaceX makes a second attempt at launching the 26th commercial resupply services mission to the International Space Station. Poor weather along the Space Coast forced a scrub of the planned 3:54 p.m. EST …

Flight Controllers in the White Flight Control Room at NASA’s Johnson Space Center in Houston successfully performed a burn to insert Orion into a distant retrograde orbit by firing the orbital maneuvering system engine for 1 minutes and 28 seconds at 4:52 p.m. CST, propelling the spacecraft at 363 feet per second. Shortly before conducting the burn, …

Live coverage is underway on NASA Television, the agency’s  website, and the NASA app for Orion’s distant retrograde orbit insertion burn as a part of the Artemis I mission. The burn is planned for 4:52 p.m. EST. Orion will fire the orbital maneuvering system engine on its European service module to propel the spacecraft into an …

RS Extravehicular Activity (EVA) #56: During preparations for today’s Russian EVA, both the primary and backup cooling pumps on EV1’s Orlan showed unstable behavior. After unsuccessful attempts at troubleshooting, the EVA has been cancelled. The European Robotic Arm (ERA) has been returned to its stowed configuration, and the crew and ground teams are backing out of the …

NASA has awarded Phantom Space Corp. four task orders to launch four CubeSat Launch Initiative missions as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract. The CubeSats will launch no earlier than 2024 on Phantom’s Daytona rocket. Building on NASA’s previous procurement efforts to foster development of new launch …

Today’s spacewalk with Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin was postponed due to an issue with the water coolant system pump on Prokopyev’s Orlan spacesuit. The team is in the process of returning onboard systems to a nominal configuration. The duo, with assistance from European robotic arm operator Anna Kikina of Roscosmos, were slated …
