Linux lands on Mars with Ingenuity

Summary

JPL describes Ingenuity as an autonomous Mars helicopter whose Linux-based computer and open F Prime software enable controlled flight far from Earth. Ingenuity landed on Mars on 18 February 2021. On Earth the helicopter weighed about 1.8 kilograms.

Ideas

  • Ingenuity flies fully autonomously because of the signal delay.
  • F Prime structures flight software from reusable components.
  • A Linux computer handles navigation and higher-level control.
  • Perseverance relays communication between the helicopter and Earth.

Insights

  • Autonomy becomes indispensable once communication does not allow real-time control.
  • Proven open components can reduce the development risks of specialised missions.
  • Redundant microcontrollers complement powerful standard hardware for critical tasks.

Facts

  • Its first controlled flight followed on 19 April 2021.

Recommendations

  • Decouple time-critical control from complex mission logic.
  • Test autonomous failure cases with recorded sensor and communication data.

Mail from the ISS: SSTV images with a Raspberry Pi and a magnetic-base antenna

From 2 to 6 October 2026, the International Space Station is transmitting twelve images via SSTV on 437.550 MHz as part of ARISS Series 33. I received them in Meerane with a Raspberry Pi, an RTL-SDR stick, a simple magnetic-base antenna and OpenWebRX+, and on the first usable pass two images came through cleanly. The deciding factor was not the antenna, but a small script that tracks the frequency during the pass and saves the images itself.

Why humanity may never leave the solar system

KG takes stock of the distances, energy, radiation, dust collisions and communication limits that make interstellar travel difficult even for advanced civilisations. The universe can be full of life, even though physical barriers almost prevent direct contact. A reachable home world gains value when escaping to other stars remains unrealistic.

Oniux: Tor isolation with Linux namespaces

The Tor Project presents oniux, which starts any Linux program in isolated Tor network namespaces. oniux is Linux-specific and written in Rust. The tool combines Linux namespaces, Arti and onionmasq.
