A new net for Mr. Steven
Photos of the ship, Mr. Steven, that SpaceX wants to use to recover its rocket fairings show that the company has installed a new net for catching those fairings.
The article theorizes that this heftier net has actually been installed for eventually catching the Falcon 9’s upper stage.
[T]he newly-installed net is by all appearances magnitudes larger, heavier, and stronger than the minimal mesh specimen it is clearly replacing. Given the fact that SpaceX thus far has self-admittedly failed to catch a gliding fairing half in the net, it seems unlikely that such a drastic upgrade would be necessitated by any field-testing that occurred since Mr. Steven’s debut late last year. Rather, a significantly more capable net seems to more readily fit alongside CEO Elon Musk’s tweet reveal three weeks prior that SpaceX would attempt to close the final major loop of Falcon reusability by recovering the orbital upper stage (S2). Estimated to weigh approximately 4000 kilograms empty, the upper stage is a minimum of four times heavier than Falcon 9’s payload fairing halves, Mr Steven’s current meal of choice.
Judging from the new net’s beefy rigging, broader bars, and general appearance, one could safely argue that it looks at least several times stronger than the mesh net before it. One could also argue that the absolutely massive metal arms installed on Mr. Steven are far larger than what might be required to catch the extremely low mass-to-area ratio payload fairings, with structural heft and bulky netting more reminiscent of safety nets present on naval vessels that are designed to catch aircraft and helicopters weighing five metric tons or more.
This is an interesting theory, but I have my doubts. At the same time, I would not dismiss Musk’s willingness to try daring engineering approaches.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

There has been some speculation that Mr. Steven could be used to catch a returning Dragon capsule, keeping it out of the water to make refurbishment for reuse easier, but with Dragon coming down under round parachutes, all the maneuvering would have to be done by the recovery ship.
Even if a 2nd stage wasn’t able to fly again, they would still get a good inspection to see how it has been performing.
