Comms Track: Spacecraft Links and Flight Software Basics

How spacecraft talk to the ground, how engineers decide whether a signal will get through, what the flight computer does with commands, and how the data is packaged. It is written for people new to the field: early-career folks and anyone switching in from IT, telecom, the military or software.

Comms covers avionics, embedded and flight software roles, the biggest group on the Mars Mining jobs board.

4 modules · about 95 minutes in all · a quiz after each module · final test: 12 questions, pass with 10 right

What's in it

  1. Module 1: The link: how spacecraft talk to Earth

    Every mission has two directions of traffic.

    About 15 minutes · quiz of 5 questions on this module · sources include NASA and JPL

  2. Module 2: Decibels, antennas and the link budget

    Comms engineers spend a lot of time on one question: will enough signal arrive to be decoded?

    About 20 minutes · quiz of 5 questions on this module · sources include NASA Basics of Space Flight, Chapter 10 and MIT OpenCourseWare 16.851 Satellite Engineering

  3. Module 3: The flight computer: commands, telemetry and fault protection

    On board, one computer usually runs the show.

    About 15 minutes · quiz of 5 questions on this module · sources include NASA Basics of Space Flight, Chapter 11 and NASA core Flight System (cFS)

  4. Module 4: Packets and protocols: how the data is packaged

    Spacecraft and ground systems from different companies and countries need to understand each other, so the industry uses shared standards.

    About 15 minutes · quiz of 5 questions on this module · sources include CCSDS 133.0-B-2 Space Packet Protocol (Blue Book) and CCSDS published standards

The full lessons, quizzes and final test are open to crew members. Joining is free.

A question from module 1

What does a spacecraft's downlink carry?

  1. A. Commands from mission control
  2. B. Telemetry and mission data sent to the ground ✓
  3. C. Only voice traffic
  4. D. Power beamed from Earth

The downlink is spacecraft to ground: health telemetry plus science or image data. Commands travel on the uplink.
