When the orbital inclination of a satellite is determined, does one take into account the steeper inclination in vicinity of the equator? Are J2 errors eliminated from an observed trajectory before the inclination is determined? Thanks in advance! Jonathan McDowell , T.S. Kelso

woah I had no idea something like Saber Astronautics exists! Basically Flightradar24 but for satellites, with everything from LEO to GEO and even beyond. tarot.saberastro.com exploring now..


Used my new MyRocketSimulator implementation to match NASA JPL Horizons first state vector of NASA Artemis I flight. The simulation is 3 seconds behind the real one, which is quite okayish, considering that no trajectory data was shared prior to this SV. Results to be published soon.



The perigee raise manoeuvre (PRM) of NASA Artemis I should have raised the perigee to 100 nm/185 km, but I saw 181 km on some websites (and no official NASA data). Where are these 181 km coming from? :-) Jonathan McDowell


Amazing experience seeing a rocket test live at SaxaVord Spaceport UK. Great job Rocket Factory Augsburg. Feel incredibly lucky to be at the right place at the right time!

Preliminary trajectory of my Rocket Factory Augsburg's maiden flight simulation to 500 km SSO with 136 kg of payload. Details to follow in the coming weeks.
