oops! iliass_tanouti I admit that's a bit of implicit knowledge of how Astropy objects work
hey! sorry for the long wait, I understand, but in this case, what is coords? and what is the point of propagating the orbit if you are not using the output (xy)?

@iliass_tanouti:matrix.orgiliass_tanoutiIf I use coord.ITRS(Spacecraft_Orbit, obstime = observing_time) I get the same coordinates as for coord.GCRS10:51:29
@astrojuanlu:openastronomy.orgjuanluastro iliass_tanouti yes, but only one of those is correct :) 17:13:27
@jorgepiloto:matrix.orgjorgepilotoI was curious about why NASA Perseverance Rover was launched today and expect to arrive to mars in Feb. 18, 2021 as posted in this webpage: https://mars.nasa.gov/mars2020/timeline/launch/ It is a 200 days trip to the red planet and here is the answer making use of the poliastro porkchops 😉19:47:39

@jorgepiloto:matrix.orgjorgepilotoIt seems to be one of the optimal transfer points for launching. So cool to use poliastro!19:48:42

The GCRS is the correct one for sure, but I don't understand why am I not getting the correct result with the other

True, it's because `poliastro.twobody.propagation.propagate` gives raw coordinates (`CartesianRepresentation`) without any frame attached to it, so when creating the `ITRS` or `GCRS` object you're making the decision

@astrojuanlu:openastronomy.orgjuanluastro We have brand new API docs using sphinx-autoapi thanks to jorgepiloto 🚀 https://docs.poliastro.space/en/latest/autoapi/index.html 08:56:38
@jorgepiloto:matrix.orgjorgepilotoI learnt a lot about sphinx-autoapi while working on this, it is a very powerful tool!09:05:00
