Rocket Lab launch on May 15 will attempt a second ocean recovery of 1st stage
Capitalism in space: Rocket Lab’s next planned launch on May 15th will attempt a repeat of the ocean recovery of their Electron rocket’s 1st stage, as they did after a November 2020 launch.
The goal of such work is to help transition the two-stage Electron from an expendable vehicle, as it was originally designed, to a rocket with a reusable first stage. And inspection of the recovered booster from “Return to Sender” suggests that this vision is no pipe dream. “We are more kind of bullish on this than ever before,” Rocket Lab founder and CEO Peter Beck said during a teleconference with reporters on Tuesday (May 11). “We reentered on a very aggressive corridor, we had no upgraded heat shield, and we still got [the booster] back in remarkable condition.”
Indeed, some parts of that rocket will fly again; the propellant pressurization system from the “Return to Sender” first stage has been incorporated into the “Running Out of Toes” Electron [launching May 15th], Beck said. [emphasis mine]
The highlighted words are quite remarkable. As far as I know, SpaceX never reused any part of a Falcon 9 first stage that was recovered in the ocean.
Rocket Lab also hopes to reduce any damage further by using new equipment on their ship for getting the stage out of the water. In addition, they have added heat shielding to the stage that should also reduce damage during its fall back to Earth.
Finally, on the next flight or so they will test something they are calling a “decelerator,” designed to slow the stage down during that fall. They are not saying what this decelerator is, which suggests it is some form of new engineering.
If all goes right, they hope to make the first snatch by helicopter of a first stage before it hits the ocean sometime next year.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I thought that SpaceX did re-use some vehicle components before they accomplished the first full-stage re-use, but I can’t point to anything right now to back up my perhaps faulty memory.
But, regardless, I think by focusing so much on re-use you’re missing the big advance of this mission: Rocket Lab is debuting their Sylda-like payload adapter that allows them to stack two non-cooperative payloads under their payload shroud. That’s how they’re able to deploy two Black Sky satellites on a single launch.
Rocket Lab is starting to be able to do the often overlooked little things that will make them a full-service launch provider. It’s not just about getting dead mass to a minimal orbit. They’re becoming more impressive with every launch.
With something small it is easier to hose off. Redstone was one of the simplest rockets to handle. Maybe X ray afterwards. HYPACC is something to look at perhaps.
@mkent: an excellent, and as noted, often overlooked, point. As was repeated in business school: ‘Compete on capability (value), not price. Someone can always do it more cheaply.’
