Launcher has demonstrated the full thrust of its 3D printed E-2 engine from NASA’s Stennis Space Center in Mississippi. The test demonstrated a thrust of about 22,046 lb⋅ft (about 10 metric tons) using LOX/kerosene at a combustion pressure of 100 bar.
Although they are still a long way from reaching orbit, a successful test like this is a huge step towards a working launch vehicle. Launcher Light will be small and very efficient, with the goal of low cost to orbit and fast completion times. But of course, it needs working engines first.
This is just one milestone among many futures for the engine; in parallel, the turbopump is tested with the required pressure of 3 times the nominal combustion pressure. These will be integrated after individual testing, and the resulting integrated engine will begin its own testing phase.
Check out the test below:
Are mega-constellations of satellites incompatible with cleaning up space debris in low Earth orbit? OneWeb founder Greg Wyler doesn’t think so. His new venture, E-Space, seeks to reconcile the two by launching a mesh satellite communications network made up of spacecraft that will also pick up small debris before deorbiting at the end of their lives.
“When we talk about building 100,000 satellites or more [ … ] we’re watching closely to make sure we’re significantly, hundreds of times, less significant and basically in the noise in terms of impact probability,” Wyler said. “So while we have more satellites than anyone else, we have a marginal increase in the likelihood of a collision.”
FAA delays decision on SpaceX space base again
In news that surprises no one, the FAA has postponed an environmental review of SpaceX’s sprawling Texas launch facility and its Starship program until at least May 31, the fourth time the agency has pushed back its own deadline.
SpaceX cannot conduct orbital tests of the super-heavy reusable Starship launch vehicle until it is given a regulatory green light. The FAA has been working on a programmatic environmental assessment since November 2020 and has received over 18,000 public comments on the project.
“The FAA is working to release the Final Programmatic Environmental Assessment (PEA) for the SpaceX Starship/Super Heavy on May 31, 2022,” the agency said in a statement. “SpaceX has made several changes to its app that require additional FAA review.”

Photo of the week
Ingenuity, the NASA helicopter currently flying around Mars, took this amazing photo of the chassis the Perseverance rover used to land on the red planet last February. As Erin Gibbons put it on Twitter: “Space debris crash landed in another world filmed by aerial drone. What time scale are we living in?
