I've been through a couple of acquisitions (in the IT world) like that. Survived the first and second round on both, but it was not pretty. Good luck in your job hunting, as I recommend you polish up your resume and at least start looking now, even if you are not submitting for any until "you k...
An L4 + L5 interferometer would be nice. That would give it one hell of a base line, even if it was only two sats/scopes. More, obviously, would be better, though I don't expect that to happen any time soon.
Too bad it would be a royal pain to get one of the satellites he was doing station-keeping on to see how they perform on the balance with and without the transceiver running.
It also sounds like the Roadster was put in it's trajectory from just the two stages? Yes. The second stage did a burn about six hours after launch to push the roadster into a larger heliocentric orbit. The target was to put the apoapsis at Mars orbit, but with the fuel it had it ended up reaching ...
My understanding is that Elon Musk wants to invest in refining existing known good hardware that meets his personal goals, such as taking rockets and making them reusable. If someone developed and built a working, usable thruster - as opposed to a research build thats only really good on a test stan...

This was the first thing I thought of when I saw the shot of the Earth behind the roadster. Glad to see I wasn't alone in that.
They did the burn about six hours after launch. It ended up not being a proper Trans-Mars-Injection burn, however. Its more like a Trans-Ceres-Injection burn, clear into the Belt, if not quite to Ceres orbit . I'd call that a success on showing off what its heavy lift rocket design can do, even if t...

Going from memory, but I thought the issue was a-periodic dips in light, as opposed to increases?
With solid state lithium batteries seemingly inevitable, even if you bought into EEStor, they're close to losing almost all of their advantages. If these advantages ever existed in the first place... Thats his point. Whether EEStor ever really worked is pretty much irrelevant if "normal" ...
It looks like a splatter of mildly viscous matter. Couldn't it just be a spurt of ejecta that cooled into that same original shape it was jettisoned as, and be one of a few/the one stray ejectus that got away? If it was hot enough to be considered plastic, it should have reached hydrostatic equilib...

The descriptions in the article remind me of some of the descriptions Johan Prinn (am I remembering his name correctly?) gave for the work he was doing.
delta v = v_e * ln( wet mass / dry mass ) If we assume the lower (sea level) Isp of 330s for the raptors, and a 100 metric ton dry mass, then you would need 3020 metric tons of fuel to result in a delta v of 11126.31 m/s. If you change the Isp to the vacuum value (375s) and ignore the presence of a...
