Comet C/2023 A3 (Tsuchinshan-ATLAS) last night. It was looking great naked eye before moonrise. Still very easy to see from a dark location.
I had the telescope out for the ISS solar transit anyway so I thought I might as well catch the comet with it.

Also I caught a fireball last night. It doesn't look as bright as one normally would because I dialed down the exposure due to moonlight. The good news is I have it on video too.

More meteors the night before last. We are entering Taurid fireball season so I'm hoping to catch one of those. Meanwhile there are several active minor showers right now so there is pretty good meteor activity in general.

WORLD’S FIRST WOODEN SATELLITE LAUNCHES FOR SPACE DURABILITY TESTS

Japan’s LignoSat, the world’s first wooden satellite, launched to the ISS as a test for using timber in space exploration.

Developed by Kyoto University and Sumitomo Forestry, the satellite is made from honoki wood and built using traditional Japanese techniques without screws or glue.

Aiming to prove wood’s resilience in extreme conditions, LignoSat will orbit Earth for six months, studying wood’s radiation resistance and potential environmental benefits compared to metal, especially for lunar and Mars habitats.

Meteor with Great Horned Owl.

I stacked the background separately from the meteor for a cleaner image using frames from video.

Captured a likely Taurid fireball this morning.

Video of meteors this morning, fireball is the 2nd one which happened just a moment after the first one.

ASTRONAUT REVEALS YEAR-LONG ISOLATION STRUGGLES: "SPACE IS MONOTONOUS"

NASA astronaut Frank Rubio opens up about emotional toll of unexpected year in space: missing his son's graduation, daughter's first year of college, and family holidays while confined to ISS's cramped 13,700 cubic feet of cable-lined hallways.

"You have the most incredible view of Earth, yet you're limited to walls of computers and cables," says Rubio, describing daily battles against isolation, physical challenges like piercing headaches and body swelling.

Astronauts exercise two hours daily just to combat zero-gravity effects.

SpaceX Dragon will now rescue current astronauts Wilmore and Williams after Boeing Starliner malfunction extended their 8-day mission to 8 months.
