>>14734306At least no ocelots were harmed.
Kerbal bros, how does this DRO thing work? Is this graphic realistic as in KSP's map view? The burns and trajectories don't make any sense.
>>14734403>Intelsat 708 SatelliteIt's more shocking that an American company had its payload on a Chink rocket.
>>14734469This looks like it's from the moon's frame of reference, that's why the transfer orbit seems to be going backwards.
>>14734469Heres another pic.I'm amused by the two TEI burns.Why lower the periapsis from DRI to get closer to the surface, only to burn again out of the Moon's SOI? Isn't that wasted fuel? Wouldn't it make more sense to make just one TLI burn from the DRO orbit?
>>14734501But why do they lower the periapsis only to do the TEI closer to the Moon's surface?
>>14734502>>14734508something something oberth effect
I don't understand why they don't use magnets. Hydraulics is not the answer.
>>14734386https://hackaday.com/2019/05/06/x-rays-are-the-next-frontier-in-space-communications/NASA'S testing a x-ray laser system for tight beam communications because it has minimal divergence at astronomical distances and can apparently punch through reentry plasma. Using a UV laser as a pump to encode bits.
morelike Demented Retarded Orbit
>>14734514But from the higher orbit the craft probably requires only a small push to exit the SOI...I never thought going back to a lower periapsis could be worth the fuel.
>tower catches starship>drops it after few minutes because hydraulics failWorst timeline
>>14734536>Starship descends to tower>keeps going until it hits the ground and explodes>chopsticks start moving among the smoke and fireTiming is gonna be a bitch
>>14734545>>14734536I imagine hydraulics are attractive because they can strongly hold so much weight, what would be another option, to so strongly and with precise timing securely clasp?And how often are there such problems with hydrolics? You see videos of factories from the 40s and stuff, or big steel Mills, and there massive machines and hydraulic presses and other things, they look like they just work non stop
>The Artemis program began in December 2017 as part of successive efforts to revitalize the U.S. space program. NASA's stated short-term goal for the program is landing the first woman and first person of color on the Moon; mid-term objectives include establishing an international expedition team, and a sustainable human presence on the Moon. Long-term objectives for Artemis are laying the foundations for the extraction of lunar resources, and eventually making crewed missions to Mars and beyond feasible.So the milestone here is "wymin and niggas"? I don't see any money for lunar bases, and even then, how in the fuck does that relate to Mars? NTP is going to take 20 more years...Sounds like they are selling the Mars snakeoil just like Elon does.
>>14734443Instead of building the first mars base, any way one of the first starships can be built as the first mars base so when it lands there is a process to convert it into a base? Would there be any way to controllably get it from a vertical to horizontal position once on Mars?
>>14734592>Sounds like they are selling the Mars snakeoil just like Elon does.Nasa is a reputable agency
>>14734592NASA can be trusted to always follow through with promises
Do the computers that control starships bellyflop to vertical landing manuvers going to simulation train on Mars atmosphere levels, and is there other ways?Like how different will the rates of fall and thruster power and angles be different in mars atmosphere? Or the thrusters just do whatever they must do so that they recieve readings that the ship is perfectly vertical?
>>14734592That's why gateway is a necessary evil, imagine if it didn't exist then the program would definitely end after the womyn and nigga landing.
>>14734620I would assume they would calculate the needed thrust depending on the scenario.Currently space tech I imagine has this but also has set parameters of mar's gravity also.I imagine it would be hard to put atmosphere into the equatinos since its not a constant, thats why current tech has been done by parachutes.Honestly it would probably be the same as on earth lasers and satelights to constantly synch rate of descent, thrusters and flats would adjust accordingly. So many variables, thats why its hard to automate and atm requires constant monitoring.
>>14734632>Implying it wont.
>>14734656There's higher chance it will continue in some way or form

PRUFROCK fits in a starship with room to spare.>It should fit in Starship which is where I’m guessing you are going. SpaceX site doesn’t list it but based on a couple of visual clues it will fit in a Starship and be roughly 1/3 the total weight. The tunnel dimensions it can dig are ~12 feet in diameter and on SpaceX site it’s shown in a graphic being transported on a flatbed truck so it’s max length is about 50 feet long. That is about 60% of the projected space in Starship cargo bay. On the weight part… A truck and trailer typical max weight is 80k lbs and some states allow a max tonnage with 3 axels on both the trailer and a drop axel on the truck to hit 100k lbs. truck and trailer weight is ~35k lbs so that means PRUFROCK has to be between 45-65k lbs or 22.5-32.3 US tons which is about 30% of the Starship projected tonnage capacity.https://www.reddit.com/r/SpaceXLounge/comments/whu4rh/elon_musk_said_the_pace_of_progress_on_mars/ij8n1qw/
