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)? | 17:09:57 |

| iliass_tanouti | If I use coord.ITRS(Spacecraft_Orbit, obstime = observing_time) I get the same coordinates as for coord.GCRS | 10:51:29 |
| juanluastro | iliass_tanouti yes, but only one of those is correct :) | 17:13:27 |
 jorgepiloto | I 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 | It seems to be one of the optimal transfer points for launching. So cool to use poliastro! | 19:48:42 |
| juanluastro | Amazing! | 20:59:53 |

iliass_tanouti yes, but only one of those is correct :) The GCRS is the correct one for sure, but I don't understand why am I not getting the correct result with the other | 22:24:42 |

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 | 08:57:56 |

| juanluastro | 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 | I learnt a lot about sphinx-autoapi while working on this, it is a very powerful tool! | 09:05:00 |
