NASA overhauls Artemis to speed lunar return with a standardized SLS

NASA announced a sweeping Artemis overhaul: cancel the costly Exploration Upper Stage, standardize the SLS for a higher cadence (about every 10 months), and push more work to commercial lunar landers with SpaceX and Blue Origin so Artemis III won't land on the Moon but will dock Orion with landers in Earth orbit; Artemis IV would be the first lunar landing, with annual missions beginning in mid-2027 and into 2028, while Gateway tower and Moon-base questions stay under review.

"Vulcan Launch Delayed to Late 2023 Due to Anomalies and Investigation"

United Launch Alliance (ULA) plans to launch its next-generation Vulcan rocket, despite recent anomalies involving the Centaur V upper stage and the BE-4 engines. The Centaur V upper stage was destroyed during a test due to a hydrogen leak, while one of the BE-4 engines exploded during a test firing. ULA is working on modifications and fixes for both issues, including adding a stainless steel ring to strengthen the Centaur V and changing the welding procedure. The first certification flight of Vulcan is expected to occur in late 2023 or early 2024, with full vehicle certification anticipated in the first quarter of 2024.

"United Launch Alliance's Vulcan Centaur Debut Faces Delay"

United Launch Alliance is delaying the maiden launch of its Vulcan Centaur rocket due to an anomaly investigation into the Centaur V upper stage. The investigation found that minor reinforcements are needed for the Centaur's thin-walled pressure stabilized tanks. The rocket's first stage performed well during testing, but United Launch Alliance wants to address potential issues on the ground before flight. The delay may result in national security payloads being switched to SpaceX's Falcon 9 or Falcon Heavy. The fix is expected to be relatively easy, and the launch could still happen this year.

ULA's Vulcan Centaur Rocket Faces Delays and Returns to Factory for Fixes

United Launch Alliance (ULA) has sent the upper stage of its Vulcan rocket back to the factory for reinforcements after a test article exploded during a structural test. ULA engineers have determined that the upper stage needs more work, delaying the first flight of the Vulcan rocket until at least the fourth quarter of this year. The Vulcan rocket is set to replace ULA's Atlas and Delta launch vehicles and is crucial for the US military's satellite launches. The issue with the upper stage's fuel tank is considered minor and can be easily fixed.

ULA Recalls Vulcan Upper Stage for Further Enhancements

United Launch Alliance (ULA) has sent the upper stage of its Vulcan rocket back to the factory for reinforcements after a test article exploded during a structural test. ULA engineers have determined that the upper stage needs more work, delaying the first flight of the Vulcan rocket until at least the fourth quarter of this year. The Vulcan rocket is set to replace ULA's Atlas and Delta launch vehicles and is crucial for launching the US military's critical satellites. The issue with the upper stage's fuel tank is described as a "minor reinforcement" and is expected to be relatively easy to fix.
