United Launch Alliance’s Vulcan rocket sits at launch pad at Space Launch Complex 41 (SLC-41) ahead of the planned Cert-2 launch on Oct. 4, 2024. Image: Adam Bernstein/Spaceflight Now United Launch Alliance is preparing for its final planned test flight with its new Vulcan rocket in the pre-dawn hours of Friday morning. The mission, dubbed Cert-2, is the second of two missions needed before ULA can begin launching U.S. national security payloads on Vulcan. Liftoff of the Vulcan rocket from pad 41 at Cape Canaveral Space Force Station is set for the beginning of a three-hour window at 6 a.m. EDT (1000 UTC). The weather forecast suggests an 80 percent chance of favorable conditions at liftoff. Spaceflight Now will have live coverage beginning about an hour prior to liftoff. Vulcan is design...

Graphic: ESA The European Space Agency is on the cusp of launching its first planetary defense mission, a complement to NASA’s 2022 Double Asteroid Redirection Test (DART) mission. The goal of these missions is to understand how Earth can be protected from a potentially destructive asteroid strike. On Thursday, the Hera spacecraft, along with two CubeSats, are set to be encapsulated inside the fairings of a SpaceX Falcon 9 rocket ahead of a planned launch on Monday, Oct. 7. The moment will begin a roughly two-year journey out to the binary asteroid system of Didymos and its moon, Dimorphos. At hand is a mission to study the impacts left by DART when it collided with Dimorphos in 2022, shortening is or...

United Launch Alliance’s Vulcan rocket made the one-third of a mile journey from its Vertical Integration Facility to the launch pad at Space Launch Complex 41 at Cape Canaveral Space Force Station late in the morning on Monday, Sept. 30, 2024. The rocket will fly ULA’s second certification mission set to launch no earlier than Friday, Oct. 4. Image: Will Robinson-Smith/Spaceflight Now United Launch Alliance returned to the launch pad at Space Launch Complex 41 with its Vulcan rocket ahead of the vehicle’s second launch. ULA needs to successfully fly this second certification mission before it can begin launching national security payloads for the U.S. Space Force and the National Reconnaissance Office. Liftoff of the mission dubbed Cert-2 is targeting Friday, Oct. 4, during a three-hour l...

The Falcon 9 second stage firing during the climb to orbit with Crew 9. Dragon Freedom reached orbit normally but the upper stage failed to perform a deorbit burn correctly. Image: SpaceX. SpaceX’s Falcon rocket fleet was grounded for the third time in three months after a second stage problem occurred Saturday following the successful launch of a Dragon Capsule carrying two crew to the International Space Station. The suspension in flights comes as the company prepares to launch two solar system exploration missions in October with narrow launch windows. SpaceX said the Falcon 9 second stage that launched NASA’s Crew 9 mission failed to correctly perform a firing of its Merlin Vacuum engine less than 30 minutes after releasing Dragon Freedom into a planned 117×128 mile (189×206 km) orbit....

The two empty seats will be used by Starliner commander Barry “Butch” Wilmore and pilot Sunita Williams when all four return to Earth next February. Image: SpaceX NASA’s 10th Crew Dragon flight to the International Space Station is ready for launch Saturday with two long-duration crew members on board along with two empty seats that will be used next February to carry Boeing’s Starliner astronauts back to Earth after an extended stay in orbit. Crew 9 commander Nick Hague and Russian cosmonaut Alexander Gorbunov are scheduled for liftoff from pad 40 at the Cape Canaveral Space Force Station atop a Falcon 9 rocket at 1:17 p.m. EDT Saturday, roughly the moment Earth’s rotation carr...
