Launcher shows off its 3D-printed rocket doing a full-scale burn

Launcher demonstrated full thrust on its 3D-printed E-2 engine from NASA’s Stennis Space Center in Mississippi. The test demonstrated about 22,046 pound-feet of thrust (about 10 metric tons) using LOX/Kerosene at 100 bars of combustion pressure.

Though they’re still a ways off from getting to orbit, a successful test like this is a huge step toward a working launch vehicle. The Launcher Light will be small and very efficient, aiming for a low cost to orbit and quick turnaround. But of course first it needs working engines.

This is only one milestone among many to come for the engine; a turbopump with the necessary 3x pressure of the nominal combustion pressure is being tested in parallel. They’ll be integrated after being individually tested, and the resulting integrated engine will then begin its own proving phase.

Watch the test below:

Greg Wyler’s new startup wants to launch a ‘sustainable’ satellite mega-constellation

Are satellite mega-constellations incompatible with cleaning up space junk in low Earth orbit? OneWeb founder Greg Wyler doesn’t think so. His new venture, E-Space, is aiming to reconcile the two by sending up a mesh communications satellite network composed of spacecraft that will also capture small debris before deorbiting at the end of their useful life.

“When we talk about building 100,000 satellites or more [ … ] we are carefully monitoring to make sure that we are significantly, hundreds of times, less impactful and basically in the noise from a probability of collision perspective,” Wyler said. “So while we have more satellites than anyone else we have a negligible increase in the probability of collision.”

FAA delays decision on SpaceX’s Starbase yet again

In news that surprises no one, the FAA has delayed its environmental review of SpaceX’s sprawling launch facility in Texas and its Starship program until at least May 31, the fourth such time that the agency has pushed back its own deadline.

SpaceX cannot conduct an orbital test of Starship, the ultra-super-heavy reusable launch vehicle, until it is given the regulatory green light. The FAA has been working on the programmatic environmental assessment since November 2020, and has received more than 18,000 public comments on the project.

“The FAA is working toward issuing the final Programmatic Environmental Assessment (PEA) for the SpaceX Starship / Super Heavy on May 31, 2022,” the agency said in a statement. “SpaceX made multiple changes to its application that require additional FAA analysis.”

Ingenuity, the NASA helicopter that’s currently flying around Mars, captured this amazing photo of the landing gear the Perseverance rover used to land on the red planet last February. As Erin Gibbons put it on Twitter: “Space debris crash-landed on another world snapped by an aerial drone. What a timeline we live in.”
