Rocket Lab tests 1st stage capture using helicopters
Capitalism in space: In early March, prior to the shutdown of New Zealand due to the Wuhan panic, Rocket Lab successfully completed a test whereby one helicopter dropped a dummy first stage over the ocean, the stage’s parachutes released to slow it down, and then a second helicopter captured it and gently transported and deposited it safely on land.
This test was part of the company’s effort to recovery its first stages so they can be reused. Because of their small size and the difficulty of developing the software, they have decided that a vertical landing is not economical. This test however shows that capturing the stage by parachute is possible. The real trick will be getting the first stage back through the atmosphere to an expected target spot and be able to release its parachutes. Proving that part of the effort will have to wait until the panic is over and New Zealand releases its citizens from house arrest.
I have embedded video of the test below the fold.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

I’ve been advocating mid-air retrieval – an established technology used by the USAF since the Fifties – for several years. If they could do it then, there’s no reason we can’t do it now. Hello, SpaceX, you can do this to recover fairings, etc using surplus C-130 or CH-53’s, no need for ships…..https://en.wikipedia.org/wiki/Mid-air_retrieval and https://www.youtube.com/watch?v=PV5nH0YGxgo
There would still very much be a need for ships as the fairing recoveries are done a long way at sea. So it wouldn’t be a matter of ships vs. helicopters but of ships only vs. ships and helicopters. Worse yet, the ships needed to host the helicopters would need to be appreciably larger than the ones now used to chase fairings.
There is also a significant difference between the aerodynamics of a vertical cylinder under parachute and a horizontal payload fairing half under parachute. Rotor downwash is a comparatively minor disturbance to the former, but a major disturbance to the latter.
SpaceX looked at helicopter recovery of fairing halves and rejected it – correctly, IMHO – for these reasons.
The fairings are to large to be recovered by anything but a helicopter. But its far safer to just pull them out of the ocean.
I am waiting until Space X changes the fairings a bit and puts directable parasailing parachutes on them. They will then be able to literally fly.
