Blue Origin has successfully launched a first commercial payload. It was a sub-orbital launch with the New Shepard rocket. The New Shepard system took 8 NASA-sponsored research and technology payloads into sub-orbital space. This flight was dedicated to NASA’s Flight Opportunities program, an essential program for researchers providing access to microgravity for technology development. Blue …
Elon Musk explained to Popular Mechanics why SpaceX switched to a 300 series alloy of stainless steel. Advanced carbon-fiber structure made very slow progress and the cost per kilogram was $135. There is a lot of cutting and they would lose 35 percent of the material in processing. It has to have a lot of …
There has been a rendering of SpaceX Superheavy Starship with two additional side boosters. Each side booster would have 31 Raptor engines like the Super heavy first stage. A SpaceX rocket with this configuration would be able to launch about 250 tons in one launch versus the 100 tons of the SpaceX Superheavy. Kimi Talivitie …
