The number of new things they are trying to do is probably too much for an iterative approach; this system is designed for Luna and Mars trips and the further away from home you go the bigger the cost in money and time becomes with that sort of approach. My point being the costs are not linear, especially with time, compared to doing that for trips into LEO.

At first the cables would be kept out of the way along the edges of the frame so the booster would have plenty of room for it's descent. As soon as the booster has descended into the frame the cables would be moved inwards. Slide rails along the booster would prevent damage to the hull (the extra weight of these would be easily affordable if they can in turn get rid of landing lags, their actuators, the power source for those and crush cores). The cables would then slide underneath the grid-fin hinges into a hook-like structure and the fins would fold down to lock the cables in place. At this point the engines would still be running to offload most of the booster's weight, and the cables could be used to guide the booster precisely above the launch stand for touchdown. Consequently the hinges, cables and frame wouldn't even have to support the full weight of the booster - so the frame could be made arbitrarily large to allow for enough margin of error. Mechanically this shouldn't be all that complicated (4x 4 motors - 2 to move the cables laterally and 2 to control tension/slack from both sides - plus an appropriate shape of the hinge so it can catch and lock onto the cable). This is quite similar to the traveling winch systems used on construction cranes - just two of them on opposing sides of the frame and used horizontally instead of vertically. Actually they would be even simpler with less pulleys, as the cable would run to the opposite side and get it's tension from there. The magic would be in the control systems that coordinate all those motors with the booster's internal guidance - but that's exactly what SpaceX does best. Winch systems are definitley capable of catching large loads - think eg. of the arresting cables on aircraft carriers - so this concept could actually work.

Scott, your a great enthusiast ! Lots of questions that beget answers and that's exactly what problem solvers want ! You will probably get a lot of credit for asking the right questions and someone coming up with the right answers. It may even be you ! Thanks !

I highly doubt that such a huge thing could be moved fast enough to be useful. I think that the hover capability and the fact that it doesn’t need to have perfect alignment might make it doable.

Instead of direct towers, two words: Arresting Cables. You could even have the cables slack so there's a larger aperture to land, and then once the rocket is over the point, swing the cables into position, catching them with hooks on the grid fins.

@Kineth1

3 жыл бұрын

Ooh, arresting cables. I like that idea. You could set up your landing zone (pit) with three towers around it, and a catch-wire going between each tower pair; use a lead-wire to draw each cable to the opposite tower, forming a 3-part snare that you close as soon as the rocket descends into it. Lets you keep the hard hardware farther from the impact point, and if a rocket does land too hard, then all you need is new cables and a bulldozer. If you make the snare 2 or 3 tier, then it can also do a much gentler job of centering the rocket too.

Your search is over, Scott because in Starship you have truly found your Cottingley Fairy. Doyle would be proud.

That's what I was also thinking. Two anchored blimps with a catch wire between them. The rocket deploy a kite with which can drag out a hook quite a ways from the rocket and make intercepting the catch wire extremely easy with their current level of guidance precision. You get much more friendly deceleration. The main point is that if you have a crew return mission they have a 2nd chance with an ejection system if the catch fails.
