Shackleton

We watched a documentary about the expedition last night. I was struck for the first time by the parallels with Apollo 13: A near disaster from which they recovered only through ingenuity and endurance (the ship was aptly named).

I only mentioned him in the book in terms of the probably apocryphal ad in the Times of London. If I ever do a new edition, I’ll probably talk more about that, as I did with Magellan.

Yesterday’s Launch

Something to finish the weekend with.

FWIW, Amiko is married to Scott Kelly, who is the Kelly twin who spent a year at ISS.

SpaceX

returns human spaceflight to America (and southern California).

I’m glad this is happening, but it should have happened years ago.

[Update just before launch time]

Welp, I guess they’ll try again Saturday. Florida weather.

[Thursday-morning update]

American spaceflight is now in Elon Musk’s hands.

[Bumped]

[Saturday-afternoon (in Florida) update]

Trying again in less than an hour.

[Bumped again]

[Update after the launch]

Looks like everything went perfectly, with weather cooperating in the last hour. On orbit now, and heading for a rendezvous with ISS tomorrow morning. Vodkapundit live blogged it.

[Update a few minutes later]

Loren Grush’s story.

Another report from Emilee Speck.

[Sunday-morning update]

And, they’re docked. They named the ship Endeavour. Jonathan O’Callaghan has the story.

So Much For SN4

It went kablooie in the static test today. Video anon.

[Update a few minutes later]

It appears to be an earth-shattering kaboom.

Not sure why there’s no audio, but I assume it was loud. Presumably no one was hurt; Mary was reportedly quite a ways away when she took this. Starhopper looks OK, but we’ll hear more soon. I was watching the live stream; it seems to be still burning. One of the benefits of stainless is that it’s cheap, compared to carbon composite.

[Update a few minutes later]

Here’s before and after.

[Update a while later]

Loren Grush has the story.

[Update a few minutes later]

And here’s Eric Berger’s story.

[Update a couple minutes later]

Worth noting, as Eric does, that the static test was successful, FWIW. So this is the biggest advance they’ve made yet on the SN series. Next challenge is to do a static test without an explosion afterward.

[Saturday-morning update]

Here’s one with audio. Note the delay due to the distance. Has to be over half a mile away.

[Update a few minutes later]

An article about the safety of the system, with a quote from Leroy Chiao: “Chiao said pushing too hard for safer numbers could cause a spaceflight program to spiral into never launching at all.”

You don’t say.

Superspreading

What causes some to transmit the disease more than others?

[Update a few minutes later]

The immune system may have a unique response to the coronavirus (also an interesting description of how viruses work).
