John Connolly is great at defining the trade space of Moon and Mars mission architectures. His workshops at ISU are fantastic.
How to select a Mars space architecture for human missions? Critical factors range from the dispersal of landing sites to how electricity is produced on-site.

There's great art of a solar-electric Mars craft on the first slide.

New Zealand is different than the U.S.
New data shows police are drawing their weapons more frequently than in the past, even as firearm and Taser discharges remain rare.
Police fired their guns just three times last year

Awesome visualization! This really illustrates the asteroids in 3D!
Yeah, the 3D modelling and availability to run forward and backwards in time, in the new @vrubinobs.bsky.social Orbitviewer App is cool!

LOOK AT THE TROJANS!

Esp. useful in changing our perspective - we no longer need to look top-down at this, we can change viewing angle for spatial distribution!

Shocking that while we are horrified at the illegal tactics used by the anonymous armed gangs claiming to be “ICE” - Republicans in Congress just voted to fund ICE at $150B - about $1000 per taxpayer - to create more armed gangs and concentration camps.

Another PET scan this morning to check on my thyroid cancer. Which means another few hours of me at home emitting 511 keV gamma rays from electron-positron annihilation. Fascinating technology. Better health through anti-matter.

A fantastic illustration of the asteroid discoveries from the first hours of observation with the Rubin Observatory. Watch this wonderful 1 minute video!

Went to a reception honoring Sir Peter Beck and the accomplishments of RocketLab. Met Sir Peter and the NZ Prime Minister Chris Luxon, and reconnected with the NZ space community, including Jess Covich.

History speaks. Europe’s lessons from a century ago can wake up and inspire our democracy…in 2025 America.

Read this excellent piece by @sciguyspace.bsky.social about how bad things got with Starliner last summer.

And be thankful for the skill, commitment, and bravery of the people behind U.S. spaceflight*

*notwithstanding some major fuckups by Boeing

Starliner’s flight to the space station was far wilder than most of us thought

Will Trump/Musk kill Artemis? Abandon the Moon?

With all the illegal and stupid things they are doing, we would not be surprised. Just another stupid move, and another slap at those Musk promoters who thought this regime would be good for space.

Senator Murphy gives a day by day summary of six weeks of corruption from the Trump regime. Unbelievable scale and scope of illegal activities.
I'm going to post this every damn day (I hope you will share far and wide) and I hope Senator Murphy @chrismurphyct.bsky.social does an update every week for us. This amount of corruption IS NOT NORMAL!

Another effect of the Musk-Trump coup.
Lots of new Facebook ads like this one in New Zealand. And friends asking how they can move to NZ.
