@BobbyBraun @NASAJPL @JHUAPL Congratulations Bobby .. welcome back to East Coast time zone 🚀 Russ J.

@ToughSf @Dennis_E_Taylor Is the off set ring meant to move ?.... if so the way it seems to be mounted will cause unbalanced torque to be removed somehow..consuming power/energy..suggest 2 opposing smaller rings..rotating opposite directions..or party on...

[Russell Joyner @RussellRocket]

@ToughSf @WebKarls @HL10PM No ... Dc-X and DC-Y .. leading toDelta Clipper were all cryogenic O2-H2 ... mass fraction was achieved with uniquely manufactured graphite composite and aluminum tanks..tiles primarily for nose re-entry.. note..New Glenn based on DC-X tech

@L5Resident Well if the nuclear fission source reactor used ceramic metallic fuel that was tungsten rhenium… At the reactor bottom if the temperature is greater than 3000 Kelvin… It could possibly have an incandescent kind of glow ....

[Russell Joyner @RussellRocket]

@torybruno It would fit nicely between Atlas III NK-33/Antares ... showing how it’s use preceded Antares ...😉

[Russell Joyner @RussellRocket]

@torybruno Relative to Atlas V

[Russell Joyner @RussellRocket]

@torybruno Great chart but RD-180 should be down with Russian engines like NK-33... since it came from RD-170... and not of American lineage ...

@DimGilmour Turn it over to see how many tiny burn thru holes ...or braze repairs ...

[Russell Joyner @RussellRocket]

@marsjoe @rossmcbride13 @aneeshswamy Joe .. look at all the beer cans under the bleacher...

[Russell Joyner @RussellRocket]

Oh .. yet Josh ..they are using super advanced cloaking tech we can’t detect..😂👽🛸

Recurring reminder: One reason to believe UFOs don’t come from space is that in the 21st Century, Earthlings have gotten *really good* at scanning space out to the Moon or farther for some pretty small objects, and we don’t see alien spaceships.

@ToughSf @MiamiCapitalist But those “stopped” neutrons turn to thermal energy in the material matrix ... so if the Mevs are too high it’ll melt the tin, you can remove the heat via conduction or convection, correctly arranged a coolant can be gasified and drive a turbo generator (Brayton cycle)?

@JeffGreason @ToughSf @plain_fiction Ok... expendable ... one way ... get it... could be very inexpensive way to explore many areas between Mars and Saturn robotically...need to do a flight demo 🤔

[Russell Joyner @RussellRocket]

@JeffGreason @ToughSf @plain_fiction Jeff - no expected charging around panels ? That might impede PVA efficiency?... I guess you can increase effective area to meet EOL power needs ... and acct. for it.

15 years ago, @elonmusk spoke at the International Mars Society Convention and I think even he couldn’t imagine where @SpaceX would be today. 🤯🤯

Europa Refueling Station.

Another quick personal piece that I've finally had a chance to finish recently.
