A house in space, with a big carport. Spaceport. You get the idea.
This illustration Skylab shows the Apollo capsule, which was launched on a Saturn 1B rocket to ferry crews to space, docked to the multiple docking adapter, which was designed and built at NASA’s Marshall Space Flight Center in Huntsville, Ala.
Single-celled algae, magnified 500 times.
They float in ponds and stream banks. I found them in the Biodiversity Heritage Library, in the Rev. Francis Wolle’s 1884 book Desmids of the United States and list of American pediastrums : with eleven hundred illustrations on fifty-three colored plates .
They look a lot better up close, don’t they?
SONG: “Facing North”.

ABSTRACT: I don’t know if this song is from March or from April; I think this might be the first time I’ve double-blown a monthly deadline for an original. At least I got a decent cover out of it.
This song is sort of built out of competing choruses, or stacked refrains. I don’t kno…
Science Art: Rufus Porter’s “Travelling Balloon,” later renamed the “aeroport,” from Mechanics magazine, Nov. 8, 1834
This airship is a kind of ancestor of the blimp or dirigible, designed by 19th-century American artist and inventor Rufus Porter, who’s perhaps best remembered today not for his drawings nor inventions, but for founding the magazine Scientific American.
From the Linda Hall Library’s “Scientist of the Day” entry (where I found this illustration):
He envisioned filling up a 500-foot-long balloon with hydrogen gas, which he calculated would provide enough lift to carry one hundred passe…
Science Art: Perspective Cutaway View of a Rotary Hammering Sample Acquisition Section (Fig. 5) from NASA Technical Reports Server (NTRS) 20150003208
A way NASA plans to get core samples from Mars, the Jovian moon Europa, and beyond – a drill designed to cut bedrock.
From the NASA Technical Report on the device:
Using an average power of 50-Watts, the drill basalt is expected to cut basalt at a rate of 0.2 cm/min down to depth of 10-cm and create cuttings and an intact core. The drill is expected to operate under different environments including Martian ambient (6 Torr and down to -50 degree C), and liquid nitrogen …
Science Art: Sinocalliopteryx gigas as a stealth hunter feeding on the primitive bird Confuciusornis, by Cheung Chungtat
An Easter Sunday lunch is served: an early bird!
This is the Chinese feathered dinosaur Sinocalliopteryx gigas, chomping the bird Confuciusornis – something we know happened because we’ve actually found a fossil with the bones of one inside the stomach of the other. That discovery was the subject of this PLOS One article, which is where the illustration came from. I like the way the illustrator made it look both like a scientific illustration and a classical Chinese draw…
