Hmm, don't know. That'd be some moon to cause a planet larger than Earth to tilt 90º. And then to disappear? Seems like the likely scenario to Uranus "sideways" rotation is an early collision. https://t.co/AeSVDjxoTG

Have to start your search somewhere, but truth is life could be anywhere outside the habitable zone, likely in frozen oceans. We have choice planets nearby (Venus, Mars) with no life but frozen worlds (moons of Jupiter, Saturn) with greater potential. https://t.co/Ol1IpGEGhe

I’ve noted before how little Enceladus–Saturn is a better candidate for life than Europa–Jupiter because the geysers are food (like vents on Earth). Gravity is very low, though, <1%. Worth a visit to scoop those geysers. #spacefarers #lifeinspace. https://t.co/72w50NJLlc

Remember that op-ed I wrote for the Baltimore Sun about #ClimateCrisis and spreading the word via productive narrative? He’s a followup from what looks like Chevron.

The new #SpaceForce song is campy, which is fine. The other armed forces have similar songs, in 4-4 time, meant for marching. No marching in zero gravity, though. They needed something more like #PinkFloyd, something to float to. https://t.co/IEgir6RWek

A brilliant test by NASA, yes. But also hints how “asteroid mining” is decades away, given complications to not just nudge but to land on an asteroid, secure equipment, and dig. Mining is “action–reaction” too, which can change the orbit of these rocks. https://t.co/Jm0kcwxqKq

https://t.co/1j3EhJiqgl—Good points but says humans unique as species causing mass extinction. Blue-green algae belched toxic gas called oxygen 1B years ago, killing much but paving way for land animals (us). Maybe a future race of intelligent jellyfish will thank us someday.

https://t.co/1j3EhJiqgl Lots of comments were about too many humans. But I think more humans = more ideas. The problem is too much inefficiency. We waste half of food and almost as much electricity in leaky grids. The earth could support 10B humans plus animals if done better.

Hmmm, don't know what to make of this one — https://t.co/j6tnENz3qB. Sure, a warmer Earth could be more hospitable to life, just not human life.

Really need to tweet more. Here’s an op-ed I wrote on the 35th anniversary of fixing the ozone hole. Remember that thing? We could have been saying “remember that climate problem thing” had we acted in 1990. #ClimateCrisis #ClimateWeek @GhostPanther https://t.co/hDiTgZRKe7

I arrived at the same number by tossing a dart at a dart board and dividing that number (12) by the number of beers I had drunk (3). My methodology might be more logical. —“There may be 4 evil alien civilizations in the galaxy” | Live Science https://t.co/Ps5sOv5uYN

So important to have two (or more) ways into space, particularly when “in Musk we trust” becomes an increasingly risky prospect. “Boeing’s Starliner Docks With Space Station for NASA” #spacefarers #boeing https://t.co/ARuTCmZrl4

Plants can germinate and grow on cotton balls, too. No surprise. Problem is that the lunar regolith can kill your if breathed in. Must be avoided. Lunar farms will be hydroponic. #spacefarers https://t.co/cZpiI2hRur

Just heard from someone close to the #NASAWebb engineering team. They’ve passed most major obstacles. The remaining tasks, although important, if failed won’t affect the entire telescope, just an instrument. That said, still work to be done before first light in 5 months.

#JWST sunshield deployed! This, IMHO, is the hardest part of deployment. Not out of danger yet, but looking good. Sunshield Successfully Deploys on NASA’s Next Flagship Telescope https://t.co/dm1CZuZJH8

Just left #NASAWebb flight control ⁦@STScI in the great city of #Baltimore. It’s now in their hands for the next nail-biting 29 days. Next: course correction at about 9 p.m. local time. The excitement really starts on day 3 when the sunshield comes out. https://t.co/ncWyKzY6kU

Congratulations #ESA #Ariane5 team for perfect #NASAWebb launch. Now it’s #NASA and #northropgrumman ‘s turn. Good luck, guys.
