Eh, start at 1.3, ramp over 10 seconds to 2.5. Fuel is cheap.

Sure, but that's not the question. The question is does BFR have the fuel capacity to do so.

There are amusement park rides will put riders under 3G for some sustained amount of time.

Re: SpaceX News

It probably wouldn't gain much time compared to the amount of fuel used, but I'm supposing BFR would have enough fuel capacity to keep at least low level thrust all the way to re-entry. This wouldn't be as fun. I'm sure if this becomes a thing, for quite some time the "space adventure" asp...

Elon just finished an AMA over at Reddit... perhaps a little tipsy while doing so.

Re: SpaceX News

700kg = the original batch of satellites launched in the 90s, NEXT or both? In any case, even with the old ones, it Wikipedia says the flare was from the antennas, not the general size. Curious if the antennas on NEXT may not need to be as big. They looks significantly different, but having trouble ...

Re: SpaceX News

Personally I think the big problem is the regulations. Currently the FAA... When first reading about Earth-to-Earth, I assumed the offshore platforms had to do with safety, noise, and lack of real estate for a launch site. But reading your post, I realize another very important reason... regulation...

Re: SpaceX News

No one is going to mention the Earth-to-Earth transportation concept? Is this lunacy or could this happen?

Re: SpaceX News

SpaceX timelines continue to work a lot like fusion timelines-- Falcon Heavy still looks close to 6 months out (for the 2nd or 3rd year running):

Re: SolidEnergy - 13 Wh in 29 g li-ion cell - any independent confirmation?

Excuse me, I guess I wasn't right either. This is Li-Metal which is apparently different than solid state lithium... I guess I need to go read some. I did find this: I contacted SES (Solid Energy Systems) yesterday, because the specs of the Hermes battery cell had a typo, I used the opportunity to a...

Re: SolidEnergy - 13 Wh in 29 g li-ion cell - any independent confirmation?

After they made press last August claiming a breakthrough, I checked up on them every couple of weeks. It has been crickets and had been assuming this was another false hope. Perhaps it still is, but happy to have hope still alive.

Edit: ... also, this is for a solid state lithium battery, not Li-ion

Re: SpaceX News

I too would love to see some excess landing fuel mass burned off using 'weight management maneuvers'! :) Well, if that was ever going to happen, it would be the next launch: 475 kg to LEO. (Contrast that with July's launch of 6,761 kg to GTO). Heck, maybe they'd even have enough fuel left for a tou...

Re: Placing humans at center of computer optimization yields hot plasmas

Another article about it at Popular Mechanics.
I had no idea Tri-Alpha and Google were working together (says they started working together in 2014). Should I have known this?

Re: SpaceX News

...except that I guess SES-11 was delayed and there will be no launches for more than a month after this. Looks like the pipeline needs a better branch predictor?
