I enjoy travelling abroad, hostels & people. At work & hobbies: radio, telecommunication, electronics, bioengineering, photography, hiking... In charge of my university's ham radio ground station, so I'm curious about space & satellite tech.

SpainSat NG II satellite, owned by Hisdesat and launched on 23 October, 2025, was hit by a "space particle" during orbit raising.

The extent of the damage is unknown but the Jan 2 press release says that "If necessary, SpainSat NG II will be replaced as soon as possible."

The impact occurred at 50,000 km, not LEO. 50,000 km is odd since geostationary orbit altitude = 35,786 km (42,164 km from center of earth).

Space debris or space rock?

This is the biblically accurate way I learned how transistors work - copy taken from the original scripture.
I've just got Open Circuits https://www.opencircuitsbook.com/ by @tubetime and W. H. Oskay, reviewed by @kenshirriff so... amazing team of real aficionados! It's been on my shopping list for years, so I'm delighted to finally own it. Randomly turning the pages and checking out the guts of devices and semiconductors with high-quality photos is a real treat!

We obtained a mysterious box of 1960s electronics. I reverse-engineered it and with much effort, we got it running. It turns out to be a test unit for testing NASA's Up-Data Link, a system from the Apollo moon landing to control the spacecraft from the ground. Let's take a look inside... 1/n

The NASA Voyager 1 spacecraft is currently sending a 4:20 hour playback of data from its 8-track digital tape recorder (DTR).

Tx rate = 1.4 kbps instead of the normal 160 bps; it requires simultaneous reception by 5 antennas at the NASA DSN Madrid site.

1.4 kbps * 4:20 hours = 2.7 Mbytes

The DTR records data from the plasma wave instrument which is sent to Earth twice a year..

Several issues onboard and on the ground have prevented such playback since July 2024.

🔴 Fallo en el lanzamiento inaugural del cohete #Spectrum de @isaraerospace.

Apenas a 20 segundos de vuelo el cohete ha perdido propulsión y se ha estrellado contra el suelo.

#OrbitIsHard Go Isar!

Wow – didn’t think I’d be in tears today, but this message sent home from Gaia as it was shut down forever today hits hard 😭

What you’re seeing is a map of the 106 CCD detectors that Gaia used to measure the positions of billions of stars in the Milky Way for the past 11 years 🛰️✨

They were turned off in a special sequence … 😕
