That's not me, but the authors of the articles I listed are a good bet.

FWIW:
Zeitlin, C. \etal. 2013, Science, 340, 1080
dose rate on trip to Mars = 1.84+/-0.33 mSv/day ~31x stratosphere jet
also arxiv:1507.03473 - dose rate on surface 0.7 mSv/d ~ 300x sealevel

Not my work., BTW

Lunar surface about half of the 1.84 mSv/day due to dirt blocking half the angles.

Moon over trees. Thin crescent smile with Earthshine above

Beautiful “smile” of a crescent Moon hanging over Westwood Village tonight so I took a shot with my iPhone 16+pro at 5x. Night mode engaged so a stack of exposures about 10 sec total. Way deeper than my eye so I edited it down. IRL could not see the Earthshine at all.

Bluish white sky with cirrus and tree branches and a big insect in the center

Saw this big bug walking on the outside of my window. Luckily it’s a lot closer than the tree in the background.

Of course it didn't actually rain at the scheduled time for the potluck.

This is great chili but I had it for breakfast and lunch.

28 qt chili pot full of veggie chili

Made a big pot of honey-spiced tofu chili for the UU Santa Monica Green Living potluck but it got canceled due to a forecast of rain. Two weeks of chili for us I guess.

Later I saw their truck-mounted giant plumber's snake.

Truck with a blue cab and a large blue cylinder in back labeled Vactor

Walking around the neighborhood this morning I saw LA Sanitation’s giant vacuum cleaner.

Are there other nuclear powered rotocraft?

Full page NYT ad filled with equations. Title is The Universe May Be Older Than 13.8 Billion Years.

Page 3 of the Science Times in the 7 April 2026 dead tree edition of the @nytimes.com is a full page ad of the equations of some guy’s cosmology theory. Looks like he presented this at the March meeting of the APS. I haven’t followed the links in the image below.

Ask and you shall receive: @philplait.bsky.social aka the BadAstronomer did the math using identified background stars and estimated the Earth was 45 degrees across in this image so the spaceship was about 8500 km above the surface of the Earth.

Congrats to the UCLA women’s basketball team who won the NCAA championship today.

48 years ago UCLA WBB won the AIAW national championship before the NCAA included women’s basketball.

On Bluesky it's
Death of Stalin - Easter Edition

It’s UCLA v USC in the NCAA WBB championship game!

Just like the classic rivalry but with the Gamecocks instead of the Trojans.

Go Bruins!

Hello, World - NASA NASA astronaut and Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft's window on April 2, 2026, after completing the translunar injection burn.

This is a great image of the Earth from Artemis II but it would be nice if the image details included more details like the time the shot was taken or the distance from the Earth when it was taken. www.nasa.gov/image-detail...

One more thing about the AI data centers in orbit schemes: the sun-synchronous terminator orbits suffer eclipse seasons, ~2 months per year with ~20 minute eclipses every orbit. So they will need big batteries too.

Of course Russia has nukes so starting a shooting war with them is risky, but it's probably the pee tape.

Dear @nytimes.com fix your sports stories on both the website and the iOS app.

NYT front page 3/29/2026

Dead tree @latimes.com and @nytimes.com both have No Kings as the lead story with a photo above the fold. But the NYT headline writer was a bit snippy and skeptical

Me holding my handmade sign reading No King! No crazy old men No insider trading traitors No Trump

No Kings today. Sherman Oaks in LA. And I met my Congressman Brad Sherman in Sherman Oaks.

They need the $200 billion to bribe the Iranians into stopping the war and opening the Strait of Hormuz.

Some traitor is clearly trading energy and stock futures based on insider knowledge of Trump's moves in the Iran war.

Is it Trump himself?
Or an aide?
If this is not stopped and the culprit arrested, then we can only conclude it is Trump himself.

The @nytimes.com spelling bee iPhone app once again failed to record progress this morning. This bug has happened many times in the past and all updates should be tested to make sure it never comes back. But apparently the QA staff is asleep at the switch.

I was trying to estimate the difference in the operations per energy for a rad-hard processor like a RAD750 versus a modern GPU. I got something like two orders of magnitude more energy per operation for the rad hard case. And ~1200 km orbits get a lot of radiation.

Morning moon thin crescent

The Moon was pretty this AM.
New Moon on Wednesday.

Thin waning crescent Moon seen through fog

It was clear last night but the morning fog couldn’t decide whether to cover the Moon or not. Later it was very foggy but then cleared up

Today was Daylight Savings Time day in the USA. Also the LA Marathon. So I had to get up at oh dark thirty then go to church on diversion since my usual route was closed. The detour was jammed but I got there. Still jammed for the ride home. Happy Sunday y'all!
