Space jobs, and the engineering to get them.

Jobs

One email a week with the space internships and graduate roles worth your time, closing date first so nothing expires unseen.

Every role links to the employer's own posting. We are not a recruiter and we do not copy anyone else's newsletter.

Learn

Worked problems in orbital mechanics, with the full working shown and a Python script behind every answer. Thermal, power and attitude control packs follow. This is how one step reads:

The free pack has six problems, from the ISS to Hohmann transfers and sun-synchronous orbits.

Build

Browser calculators for the budgets a student satellite team argues about: mass, power, link and thermal. None are live yet. When the first one works and is checked against a worked example, the list hears first.

The engineering behind it

Short explainers on how space hardware actually works, each with the calculation on screen. The first set:

• How fast the ISS moves, and why it never falls down.
• Why geostationary orbit sits at 35,786 km and nowhere else.
• The Hohmann transfer, the cheapest way to reach geostationary orbit.
• Why many Earth-observation satellites orbit at about 98 degrees, and what sun-synchronous means.
• The cost of a plane change, and why you do it where the satellite is slowest.

Who runs this

Star Tracker is built by engineers, for engineers. The writing and the code are made with AI tools. Every number in a pack or an explainer is computed by a script and checked against a textbook value before it is published.

Everything is written from scratch. It is not copied course material and not assignment answers; it is for understanding the method.
