tater Posted July 30, 2019 Share Posted July 30, 2019 https://www.nasa.gov/press-release/nasa-announces-us-industry-partnerships-to-advance-moon-mars-technology Quote SpaceX of Hawthorne, California, will work with NASA’s Kennedy Space Center in Florida to advance their technology to vertically land large rockets on the Moon. This includes advancing models to assess engine plume interaction with lunar regolith. Quote SpaceX will work with Glenn and Marshall to advance technology needed to transfer propellant in orbit, an important step in the development of the company’s Starship space vehicle.

It sounds to me that NASA needs SpaceX a lot more than they need NASA atm They better at least be getting paid handsomely for it.

( Who really cares what the engine exaust will do to the lunar dirt btw Apollo seemed to get by fine ) I think it's that SpaceX can use the facilities and expertise, and NASA can use the data sort of thing, with no transfer of money. But I may be wrong. Apollo didn't have to use that engine again. Quote Link to comment Share on other sites More sharing options...
Wjolcz Posted July 30, 2019 Share Posted July 30, 2019 (edited) NASA is taking Starship seriously? I'm becoming less and less skeptical of flying water towers. I sometimes wish to take just a tiny peek into the future and see how well all those SpaceX plans went and which got changed and which ones worked/didn't work.

Which, IIRC, would sustain considerable damage as it was, just from the interaction of the plume with the surface. Sadly, the real world is not the Kerbalverse where you can just land on your engines. 20 minutes ago, Wjolcz said: sometimes wish to take just a tiny peek into the future and see how well all those SpaceX plans went and which got changed and which ones worked/didn't work.

Apollo 15 did. The Apollo descent motor nozzle was designed to be crushable, because they knew they had very limited control over how smooth the terrain was and they didn't have a great deal of clearance between the landing leg pads and the nozzle. Starting with Apollo 15 they had even less than before, because the extra mass of the rover required them to use a bigger nozzle in order to get more performance from the descent engine.

While Dave Scott certainly did thump it down, the nozzle didn’t actually contact the surface, it buckled due to (relevant subject!) firing so close to the lunar surface, as mentioned here (about 10:00 in): Hence why the whole subject needs further study. Either way, still wouldn’t wanna take off with it. Edited July 31, 2019 by CatastrophicFailure Quote Link to comment Share on other sites More sharing options...
Listy Posted July 31, 2019 Share Posted July 31, 2019 If a lunar base is ever established, it also sounds like NASA & SpaceX would both be keen to get a better handle on how best to stop everything nearby (habitats, rovers, equipment, astronauts etc) from being turned into a sieve every time a rocket lands or takes off nearby and starts flinging dirt around at 3km/s in an environment where there's no air to slow the debris down. http://www.planetary.org/blogs/guest-blogs/2014/0419-forensic-ballistics.html " The exhaust of the Shuttle’s solid rocket boosters pulled several thousand bricks from the wall of the launch pad’s flame trench, slammed them into each other, creating many thousands of fragments, and blew them as far as a kilometer from the pad."

Xd the great Posted July 31, 2019 Share Posted July 31, 2019 (edited) I think, maybe a flame trench dedicated to landing? First rockets land simutaniously, sets up infrastructure for a landing pad. Other rockets use that pad for propulsive landing, bringing a lunar base with them. Edited July 31, 2019 by Xd the great Quote Link to comment Share on other sites More sharing options...

Guest Posted July 31, 2019 Share Posted July 31, 2019 Just now, tater said: https://sciences.ucf.edu/class/landing-team/the-science-of-plume-effects/ interesting. Also seems like good news for Starship if they are actually doing this kind of research. Makes it more real somehow. Poor BO... If Starship is landing on The Moon that lander seems pretty obsolete. Maybe there will be a market for delivery of robot missions to the surface, but put that next to what is basically a giant chrome hotel... it seems pretty (insert word here that the language filter will turn into "excrement") XD Quote Link to comment Share on other sites More sharing options...

They have to fly to orbit first (Starship), then work out the refilling ops. Long poles. As for BO... They have to fly to orbit first (with literally anything), then work out transfers and lunar landing, lol. Long poles. Quote Link to comment Share on other sites More sharing options...
kerbiloid Posted July 31, 2019 Share Posted July 31, 2019 Spoiler The first thing the Starship troopers had seen on the Moon was a rocket nosecone on the horizon. Watching at it in binoculars they read: "New Musk". Quote Link to comment Share on other sites More sharing options...

Ricktoberfest Posted July 31, 2019 Share Posted July 31, 2019 What about putting some Super Draco’s higher up on the fuselage? Can act as a landing engine high above the surface and also an escape system if the craft could be split away from its fuel tanks somehow Quote Link to comment Share on other sites More sharing options...
