- For
- UK and European students pursuing space engineering roles
- Worth noticing
- The ISS example uses constants from Vallado’s fourth edition and checks a 420 km orbit against a script-computed speed and period.
Field notes
The sample lesson starts from a 420 km circular orbit and displays the radius, speed, period, and orbits per day, with the solution’s arithmetic left visible. Its job listings are described as UK and European internships and graduate roles sorted by closing date, each linking to the employer’s posting. The site also says its future budget calculators will use the same models as its courses; several are marked as coming rather than live.
