VideoCrucial first fueling test on tap for SLS core stage later this month
If all goes according to plan, engineers in southern Mississippi later this month will load cryogenic propellants into the core stage of a rocket NASA says will launch astronauts back to the moon, exposing its tankage and internal plumbing to extreme operating conditions hundreds of degrees below zero for the first time. The fueling test -- a major milestone in its own right -- is a precursor to a high-stakes eight-minute test-firing of the Space Launch System's four shuttle-era main engines planned as soon as November.
VideoLive coverage: Cygnus supply ship arrives at International Space Station
A Northrop Grumman Cygnus supply ship packed with fresh food, experiments, and a new toilet for the International Space Station approached the orbiting research lab Monday, two-and-a-half days after launching from Virginia aboard an Antares rocket. Capture of Cygnus with the station's robotic arm occurred at 5:32 a.m. EDT (0932 GMT).
VideoLive coverage: Delta 4-Heavy countdown halted in final seconds
United Launch Alliance scrubbed the launch of a Delta 4-Heavy rocket Wednesday night less than 10 seconds before liftoff from Cape Canaveral, the second such abort suffered by this mission.. The launch of a classified National Reconnaissance Office spy satellite is expected to be delayed at least several more days as engineers assess the cause of Wednesday's last-minute abort.
VideoLive coverage: Launch of Delta 4-Heavy aborted seconds before liftoff
The launch of a United Launch Alliance Delta 4-Heavy rocket from Cape Canaveral was aborted three seconds before a planned liftoff at 3:28 a.m. EDT (0728 GMT). The rocket was set to loft a classified payload for the National Reconnaissance Office, the U.S. government's spy satellite agency.
VideoDelta 4-Heavy likely heading for geosynchronous orbit with surveillance payload
The top secret intelligence-gathering payload for the U.S. government set for launch Tuesday on top of a Delta 4-Heavy rocket is likely the next in a line of sensitive eavesdropping satellites designed to intercept radio signals and other communications traffic from adversaries around the world.
VideoVideo: Rocketcams show Mars-bound rover’s ride into space
Cameras mounted on United Launch Alliance's Atlas 5 rocket show the fiery ride into space for NASA's Mars 2020 Perseverance rover after taking off from Florida's Space Coast.
VideoDragon astronauts describe sounds and sensations of return to Earth
Two days after becoming the first U.S. space fliers to splash down in the sea in more than 45 years, astronauts Doug Hurley and Bob Behnken on Tuesday described their fiery ride back to Earth aboard SpaceX's Crew Dragon capsule to cap a "flawless" test flight, setting the stage for operational flights beginning later this year.
VideoLive coverage: SpaceX crew capsule splashes down in Gulf of Mexico
NASA astronauts Doug Hurley and Bob Behnken returned to Earth Sunday with an on-target splashdown in the Gulf of Mexico at 2:48 p.m. EDT (1848 GMT) Sunday. The astronauts completed a two-month stay on the International Space Station on a test flight of SpaceX's Crew Dragon spacecraft.
VideoAtlas 5 launch timeline on the Mars 2020 mission
This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into space from Cape Canaveral with NASA’s Mars 2020 mission.
VideoULA’s Atlas 5 is NASA’s go-to rocket for nuclear-powered space probes
NASA's Perseverance rover, set for liftoff Thursday on a journey to Mars, posed some unusual challenges for launch crews working with the robot's plutonium-fueled power generator, but United Launch Alliance's Atlas 5 rocket is uniquely suited for the job, the company's CEO says.
