The Space Shuttle SRBs were of course the slowest at around 5,000 km/h, followed by the Electron booster at around 7,500 km/h, then the Falcon 9 at around 8,000 km/h, then the F9 fairing at 8,500 km/h and lastly the Vulcan booster which will almost reach an astonishing 20,000 km/h!!

Multiple engines create some recirculating flow regimes that they have to deal with anyway.”They also will need to add some type of control system to make sure the stage maintains a proper and controlled orientation throughout reentry. Then a freaking airplane would swoop by with a giant hook on the back and snag it out of the sky. The good news is that s1 mass has a much lower effect than any other stage on payload”So luckily the first stage takes a lot less of a performance hit than an upperstage.

Instead, Rocket Lab’s plan is slightly more complicated. Sign up for the In an expertly choreographed air display, a helicopter will swoop in, snag the rocket, and carry it to a nearby ship.Rocket Lab is still a long way off from catching the Electron with helicopters. Do you think the Electron will survive the wall? Everyone is working feverishly on making a better battery since batteries are officially in absolutely everything.From where I’m sitting right now, just in this room alone I can count at least 5 devices which all run on lithium Ion batteries and I’m not even counting the dozens of camera batteries I have for various cameras.Now Rocket Lab mentioned massive upgrades to their Electron, and it might be safe to assume they unlocked a little extra potential via battery upgrades and additional tuning, but that’s yet to be confirmed.Another fun thing to remember is due to their electric pumps the Electron can actually run to tank depletion, something a turbopump engine can’t do safely. This may be some cold gas thrusters or even small aero features.Peter Beck didn’t comment on how exactly they’ll control it, but he did say there will be some control systems because they have a narrow corridor to make it work.I assume that means they have a very precise reentry trajectory and perfect angles of attack that seem to be conducive for a successful reentry.But he did mention they have some “supersonic decel devices to scrub velocity as best we can” so we know they have the ballute, but I’m thinking they might also have some other tricks up their sleeves to scrub off velocity at supersonic speeds, maybe even air brakes on the interstage or near the base.I’m not going to read into the computer animation too much, but I can’t help but think these shiny bits on the interstage and near the bottom look quite different than their production interstages and thrust section.If Kerbal Space Program has taught me anything, airbrakes really can help scrub off a lot of speed and they can also help to maintain orientation.But for my own personal speculation, I definitely think surviving reentry without any kind of propulsive burn is going to be impressive.

It also intends to launch from Virginia in the U.S. starting in 2020.The company revealed its Photon satellite platform earlier this year, which would allow small satellite operators to focus on their specific service and use the off-the-shelf Photon design to skip the step of actually designing and building the satellite itself. Rocket Lab has already demonstrated other maneuvers needed to make its Electron rocket reusable as well. Taking a page from SpaceX’s playbook, Rocket Lab’s CEO says the company will try to recover the first-stage booster of its Electron rocket to save time and money. So fast that the Vulcan will likely see around 60 times more heating on reentry than the Space Shuttle’s SRBs. There are a number of steps required to get to that point, but already, Rocket Lab has been looking to measure all the data it needs to ensure this is possible through its last few launches.
