IIRC, I took an electronics class in the UW physics department with Prof. Dehmelt.
What a life story! Former German WWII POW becomes physicist, wins Nobel, and proposes to wife-to-be on the day he wins the prize:

Mosses and lichens would likely be among the first organisms to survive in the open on Mars during terraforming.
Lichens grow as little as 0.04 inch (1 millimeter) every one hundred years, and some patches may be more than five thousand years old. Mosses are not as hardy as lichens and also grow slowly; a boot print in a moss carpet may be visible for years.

The question of an idle moment turns up some interesting claims about the number 2017, which I hardly have time to vet!

I see Orbital as kind of Space 1.5. They have done some innovative things but are mostly dependent on the Space 1.0 supply chain. They did recently create one of the most memorable rocket explosions recently, although that's not really to their credit.

Ah, good. Splashdown and imminent recovery.

Evidently there will not be live splashdown coverage.

From SpaceflightNow:

Ignition of the capsule's thrusters is set for 9:55 a.m. EDT (1355 GMT) for an appoximately 10-minute deorbit burn. Splashdown a few hundred miles west of Baja California is scheduled for 10:54 a.m. EDT (1454 GMT).

The Mote in God's Eye is usually within my top five, and always within my top ten, science fiction novels*. In my youth, even as a poor college student, I would often almost resent it** when Heinlein came out with a new novel, because I would enter an algorithm by which as soon as I saw it on the stack at the U bookstore I would walk half a block to the ATM and then half a block back to buy the book, no matter the status of my checking account. Hardback. Sometimes cursing in sort of a reflexive Shadenfreude.

Anyway, suffice it to say I today have a much more nuanced view of Heinlein and others, and have read Patterson's biography.

All that said, if you have any interest in the above, and haven't read it yet, you will surely be delighted to follow the supplied link, a letter from Robert to Larry and Jerry after reading a draft of their epic novel.

*I don't really keep a list, but if one were to ask me off hand, this is probably how it would break down.

**Right, not really.

I have to say it: Dung mosses are simply the shit.

Clearing the backlog. A legless F9 takes a heavy payload to geosynch.

Successful deployment of @EchoStar XXIII to a Geosynchronous Transfer Orbit confirmed.


I appended the following to the pinned post describing this collection:

Policy: I welcome +1s and cogent comments that might even lead to a discussion. I will likely delete very short comments like "great!". Questions that are easily answered using basic web searches might also get deleted. Stupid comments and spam will get deleted and the commenter possibly blocked.

I've kind of been doing some of this already and don't really like extensive policy statements in peoples' collections/communities. However I don't think this one is particularly extensive!
