Well, that's just because Earth and moon are too far apart and don't both have an atmosphere. If they were closer, you could totally do that, just watch for the microgravity around the barycenter. Better still, you could do that e

Does anyone actually know what the real cost for the customers will be once the free AI money no longer floods those companies?

Orion drive is one long line of bangers by definition! ;-)

While the Orion drive indeed works perfectly fine in atmosphere - or actually even better than in vacuum - no one says you need to launch them from the ground. While it would be preferable due to the immense weight, you can either lift it b

I am not sure about your experience, but these types of channles seem to mostly have the issues of people being to bussy to repply, but when they do, there is often an interesting interaction & this is how users often become contributor

It also helps that apparently in general street parking is banned (possibly at least in big cities) due to disaster considerations - eq. for easy access for rescue personnel after a major earthquake or Typhoon. Not to mention tightly parkio

Sure, even with Falcon 9 many found it iffy to have so many engines - but it turned out fine. Hopefully modern control hardware and QA can handle also 30+. :)

Long term definitely like this! BTW, this exact sequence can be seen at the start of the Space Odyssey movie, with the main character traveling from Earth to Moon.

I agree, but still - what could they have used that was not "build your own engine" ? They seemed to have preferred (or maybe were forced to ?) use off the shelf hardware, even if sub-optimal. The only engines that were not hyperg

There are is a way[1] how to gate a spacecraft 5x stronger (basically on the level of battleship style steel plate) to orbit - and then to Titan and back. The propulsion method just has some unfortunate side effect when launching from earth

Starship has 3 sea level engines for landing + 3 vacuum optimized engines.

Depending on your mission profile, there are more ways how to get to the Moon and possibly back - the Surveyor space probes did direct ascent without entering lunar orbit & massive burn with an embedded solid rocket engine just before l

Yeah, this is a remarkably good score - for comparison Europe is at 0 out of 2. :P The first one [1] actually landed but failed to send back any data (kinda like the soviet example) due to deployment failure. But the second one will at leas

Sure, but AFAIK the V1 design just wasn't mass effective for the goals of the program - eq. lifting usable payload & being fully reusable. Still in hindsight, a couple more flights to test the improved heat shield could help move t

I think they requires Raptor 3 engines & they are apparently still finishing their development. So might as well use up the remaining Starship 2 & Raptor 2 inventory in destructive testing (both intentional and emergent).

The Saturn V second stage (S-II) has at least two examples listed as destroyed during testing: https://en.wikipedia.org/wiki/S-II "First all-up S-II stage, assembled between 1963 and 1965. Completed several engine

>A little Estes toy rocket lifts off the pad much more aggressively (in the blink of an eye!) than a full size rocket... If you really want to, you can reach Mach 10 (~3300 m/s) with a 8 meter long 3500 kg missile in 5 seconds : h

I think a steam locomotive would be even cooler - first steps to Galaxy Express. ;-) For example 2 of the legendary JGR Class 8620 (nicknamed hachiroku) Japanese steam locomotives could be comfortably launched to orbit in 90 tons. :)

There are definitely some parallels, but it is not the same in many regards. For example the N1 was severely hampered by engine availability - Glushko wanted to push his hypergolic rockets and engines and refused to build an engine like he

I think those were available off the shelf at thet time ? Not sure what else would be suitable in early 90s, provided you did not build your own like basically all modern rocket companies since then.

Interesting - I was never sure about the exact mechanism m, just that the orbital speed & lift provided by wings were part of it. :)

Not to mention the comparable Soviet N1 rocket never launching successfully before being canceled.

They are finishing another pad on the launch site & the explosion happened on a separate test site from the main launch site.

With the Amos explosion on Falcon 9 IIRC the issue was with burning kerosene seeping into the pad, damaging it quite a bit. Both methane and liquid oxygen should burn or evaporate before really pooling on the pad infrastructure, so there co

In "normal" project a serious misshap of this kind often ends the project - see how the DC-X VTVL rocket testbed fell over due to one landing leg not extending, ending the whole project. Nothing related to what was being tested or
