okay but hear me out, space rocks — meteorite edition.

to anyone who ever said rocks aren’t cool, you’re wrong.

Today, spacecraft Osiris-REx is scheduled to stow its sample canister inside its hull, after collecting so much material that debris has literally been leaking out of the sample container for the past few days. This video, based on images collected by the spacecraft, shows the view that would have been seen as the spacecraft descended, contacted the surface, and released a pulse of gas to drive debris into the sample container.

CHONDRITE SÉANCE / James Yeary

Imagining someone unlike myself awakening musical unities The wine-dark sea holds the stars in its cup These single-point constellations the last sailors shed of individuation transfigured in the fog of sea·map·sky the drumming is incomprehensible commanding while side-stepping the private as nerves muscle their way into hammers the word slinks from its brief biography. We wear the hole in the light as our badge sight returned one hundred twenty years it climbs my face, looking for the name. Kudos searing to the throat on its own now I know what everyone else knows The thighs are wise to what the thyroid is doing Telemachus disappears into her command a vent of cortisol burns my eyebrows every void with their identity. ⁂ James Yeary is interested in the mitigation of personality for the sake of Martian influence. His most recent chapbook is Hawai’i (violaceous euphoRia, 2019). He has taught collaborative writing as an art practice in the classroom, at the museum, and on the street.

The Allende meteorite

The Allende Meteorite is the largest of its kind ever found on Earth. It is often referred to as the most widely studied meteorite in history. The fall of this meteorite was viewed in Chihuahua, Mexico in the early hours of February 8th, 1969.

It is a carbonaceous chondrite (most primitive type of meteorites), a class of *chonditic meteorite. The meteorite is quite distinguished due to the high quantity of calcium-aluminium-rich inclusions (CAI).

Allende hit Earth only a few months prior to the Apollo 11 mission. As one can imagine, it was an exciting time for numerous scientists. Many labs and museums dispatched teams to site to collect samples of the meteorite. The Smithsonian Institution was one of them.

The **chondrules and CAIs found in Allende are approximated to be 4.57 billion years old.

The age of this type of meteorite is often taken as the age of the Solar System due to the fact that they have experienced the least mixing since the formation of the Solar System itself.

*Chondritic – chondrite – non-metallic meteorites that haven’t been altered due to melting of the parent body.

**Chondrules -molten or partially molten droplets. Found in chondrites.

Note. Calcium-aluminium-rich inclusions are part of the oldest substances created in our Solar System.

NWA 5491 CV3 Carbonaceous Chondrite slice weighing 19.8 grams. This class of meteorite is the most primitive of all the meteorites and contains ancient chondrules (round grains) and calcium aluminum inclusions (CAI’s) (white irregular patches) that are situated in a dark matrix of solar nebular dust. Chondrules are the basic building blocks of the planets.
