Star Tracker

Space jobs, and the engineering to get them.

A free weekly email of internships and graduate roles at space companies and agencies in the UK and Europe, sorted by closing date. Plus worked orbital mechanics problems where every number is checked by a script.

Would you pay about £7 a month for the full job tracker, every problem pack and the calculators?

We email you a confirmation link first; clicking it sends the free pack. Then one email a week. Unsubscribe from any email. Details in the privacy notice.

Jobs

free, by email

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.

free sample pack

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:

ISS, circular orbit at 420 km
r = R_E + h = 6378.137 + 420 = 6798.137 km
v = sqrt(mu / r) = sqrt(398600.4418 / 6798.137) = 7.657 km/s
T = 2*pi*sqrt(r^3 / mu) = 92.97 min

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

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

explainers coming

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.
