Ah, an update. I had hoped to find something like this on my return from vacation.
 
More on the SpaceX investigation and the state of their facilities.

Credit: US Launch Report. The investigation into a dramatic Falcon 9 rocket explosion earlier this month at Cape Canaveral has determined a “large breach” in the launcher's upper stage helium pressurization system led to the destruction of the booster and its $200 million satellite payload, ...

Did they ever find out what flew by when the rocket blew up

Some lichens on a stone wall in Joellenbeck, Deutschland (a suburb of Bielefeld - what you've never heard of Bielefeld either*? - where almost nobody speaks English).

Fortunately, I speak a little Deutsch, and stress makes a person give it their all! Some people have a little English, which really does make it easier.

*Unless you have! If so: points!

The whole abort system seems like a 70's-derived Rube Goldberg cartoon.

And the whole idea of such an expensive rocket that launches only occasionally seems silly.

OTOH, India's PSLV is kind of Rube Goldberg, but it's operational.

But SLS/Orion is a thing, a thing that generates #picturesofrockets!
 
@NASA_Langley more science money wasted on obsolete tech. More to be wasted as system is build for inefficiency and waste. Brauo K. 2h2 hours ago. Brauo K @psj211. @NASA_Langley Record waste of science and space budget by NASA politicians and greedy contractors.

Imagine having a network of eyes in the sky with targeting and quick turn around (measured in minutes) of spectral data.

Upcoming launch of Blacksky's Pathfinder-1 on India's PSLV, built by Jason Andrews' SpaceFlight, Inc.

This probably marks me as immature, but the largest payload they are launching is called Scatsat. Lol, I guess since they're not expecting to keep it in orbit for more than a few years, the name makes sense.

More than a decade ago, I visited Paris and bought a Roald Dahl paperback at this English-language bookstore (note: English-language books are very expensive in Paris). I had hoped this time to buy a Moorcock paperback, any one, as my Dahl from previous years had been imprinted with their stamp, and I thought it would be fun to have a Moorcock so imprinted*. Alas, there were no such.

*You get points for knowing why off the top of your head!

I only hope it's an obvious easily fixed thing, like the incompatible metal fastener on the early Falcon 1.

Dear NPR: Gelsemium is a flowering plant, not a fern. How's that fact checking going for you today?

This really needs to get reshared more often.A self-contained, no-nonsense infographic.
 
It was National Science Week in Australia earlier this month, and I attended the informative and entertaining State of the Universe VI public lecture at Swinburne University. There was some discussion on the elements and the formation of matter that particularly piqued my curiosity - which elements come from where? And what are the proportions of those elements here on Earth?
The lovely chart below answers that first question.
