When's Musk's green hydrogen car coming. Possible game changer for all.

honestly I can't see it. Hydrogen is a slippery bastard of a gas- it escapes containment way too easily (and has a tendency to explode).
I can see methane extracted from atmospheric carbon being a thing, but I'm optimistic.

Apparently it's fine margins of getting this reuseability rocket thing working as the earth's gravity is so strong
if gravity was 2% stronger we couldn't get to orbit with chemical reactions (ie rockets). It's nuts.

really? thats mad, this planet really is this crazily unlikely goldilocks sweet spot

Nah. Planet will be fine, once it gets rid of what's killing it (us).

@nzzp What's that plume emittance from the booster after it separates from starship and descends to earth.
presume you mean this?
I don't know! But guessing (in the Fern way), I presume it's water vapour from slowing down (aerobraking)
It's a rapid change in pressure cooling the humid air from where they air launching from. So yep, condensed water vapour.

Well Musk calls Fuel Cells "Fool Cells", so not very likely.

Images of Jupiter from the Juno probe:
JunoCam : Processing - Mission Juno
Download raw imagery from JunoCam and upload your processed imagery to the gallery!
North Pole at Minimum Emission Angle
The image is reprojected according to a preliminary geometrical camera model, cleaned from some of the camera artifacts, approximately illumination adjusted with a 3rd degree polynomial BRDF over the cosines of the incidence and emission angle on the basis of PJ50 images, linearized to radiometric values, white-balanced with linear factors (0.629;1.0;3.65) for (R;G;B) on the basis of inbound PJ63 JunoCam images, and displayed with gamma=2 with respect to the square root of radiometric values.
Resolution is 30 pixels per degrees in an equidistant cylindrical system centered to the camera at image stop time, with an axis parallel to Juno's spin axis. The rendered field of view is 60x180 degrees.

No idea what Rocket Lab are up to here, but didn't they get some US military contracts?
Rocket Lab launches mystery mission on company's 12th launch of 2024 (video)
Liftoff of the mission, which was for a "confidential commercial customer," took place at 5:56 a.m. ET on Tuesday (Nov. 5).
I saw Peter Beck's heli (an Airbus) at my local airfield yesterday. One of the guys spoke to him and he was visiting the Sail GP facility that they purchased recently (it's just down the road from the airfield). Apparently some new fin components or something being designed / built there. Quite cool having all that on my doorstep, should see what jobs they have going...they might need a mail boy or something...

As for Rocket Lab, it's be spy satellites most likely, but often commercial flights don't want to share competitive advantage/details.
Yeah. It took around 10 weeks or something from the signed contract until the launch. That is usually 2 years apparently so quite some advantage!

Once Tesla moves into tanks that might change...
