Rocket Lab is taking an enormous step towards its first-ever rocket reflight.
On Jan. 31, one of many firm’s Electron rockets launched 4 personal satellites to Earth orbit. The automobile’s first stage then got here again down for a mushy ocean splashdown, and Rocket Lab fished it out of the ocean and hauled it again to shore for inspection and evaluation.
The corporate has recovered boosters on this method a number of occasions prior to now, gathering details about how you can make Electron first levels reusable. However this explicit booster will break new floor: Rocket Lab is returning it to the manufacturing line for last testing forward of a possible reflight.

“By an iterative growth course of, we now have methodically perfected every step of Electron restoration whereas concurrently persevering with to extend our Electron manufacturing capability and launch cadence. That is the thrilling last piece of the puzzle earlier than Electron goes reusable,” Peter Beck, Rocket Lab’s founder and CEO, stated in a press release final week.
“Our key precedence in pushing this stage again into the usual manufacturing circulate for the primary time is to make sure our techniques and qualification processes are match for accepting pre-flown boosters at scale,” Beck added. “If this stage efficiently passes and is accepted for flight, we’ll take into account alternatives for reflying it within the new yr.”
This booster has already handed extra assessments than some other recovered Electron first stage so far, in accordance with Rocket Lab, together with a pressurization check, helium leak examine and carbon fiber structural testing. On this upcoming last part, the booster can be put via the identical rigorous trials as a brand-new Electron tank to ensure it has the inexperienced mild for reflight.
Rocket Lab has been engaged on making Electron first levels reusable for a number of years now. Over that point, the corporate has made quite a lot of modifications and advances in that course, together with (in accordance with final week’s assertion):
- “Making certain Electron’s carbon composite construction survives the extraordinary warmth and forces of atmospheric reentry via progressive coatings, warmth shields, and superior response management techniques to regulate the angle of reentry.”
- Refining the parachute system to make sure dependable deployment and easy deceleration from greater than 2,300 meters per second to 10 meters per second.”
- Honing the telemetry and monitoring techniques so the marine restoration group can find the stage as quickly because it splashes down.”
- Streamlining the method of gathering the stage from the water in lower than an hour, then making certain secure transit again to the Rocket Lab manufacturing advanced.”
- Profitable launch of a beforehand flown Rutherford engine.”
If Rocket Lab’s efforts are profitable, the 59-foot-tall (18 meters) Electron will grow to be the primary small orbital launch automobile ever to sport a reusable first stage.
SpaceX’s Falcon 9 and Falcon Heavy rockets famously have reusable boosters, however each of these launch autos are a lot bigger than Electron, which was designed to offer small satellites devoted rides to orbit.
