Last month, we traveled to Beijing to attend an academic conference and met at Beihang University to discuss the development work of the propulsion subsystem for the Hyacinth Satellite.

Iridium 51 reentry was observed from northern China at ~10:56 UTC on 2026-03-14, nearly 8 years after its perigee-lowering burn.
Notably, 26 uncontrolled Iridium satellites remain in orbit, 23 of them still at 700–800 km altitude.
🚨Holiday Non-Earth Imagery 🚨
We captured a pre-mission test run ahead of Santa’s primary operation.
Our analysis confirms:
- Stable attitude control
- Payload verification and mensuration of the primary gift bag
- One probable Rudolph identified on board
From the team at HEO, we wish you all a very safe and happy holiday!
Building a hacker’s lab for satellite analysis: not cheap, but practical and super fun! 🕹️၊၊||၊🛰️💥🌎

Huge thanks to USTC for hosting the event and building an open, high-quality platform for amateur radio and space engineering.
Hyacinth will continue pursuing our vision: bringing more people into space through practical,accessible engineering.
Stay tuned for more updates!
