| Dec 22, 2021 at 12:35 | comment | added | BrendanLuke15 | A note on computation time: on my 'machine' (~$1500 CAD laptop) I can calculate ~70,000 trajectories per minute (Type I, II, III, & IV trajectories, Matlab, Gauss problem algorithm from "Fundamentals of Astrodynamics" by Bate, Mueller, & White (1971), w/ Matlab built in root finding). | |

| Dec 21, 2021 at 7:29 | comment | added | Armadillo | Ryan - alternatively if you want to have a go at creating your own script to generate porkchop plots and you already know a little python, I can highly recommend @Alfonso Gonzalez 's excellent YouTube channel. This video in particular addresses this point: youtube.com/watch?v=aN05hfPCG2M&t=184s | |
| Dec 20, 2021 at 22:33 | comment | added | uhoh | @DavidHammen I like the expression "excess spewed nonsense" because it resigns us to the fact that much on YouTube will have an average, perhaps even acceptable level of spewed nonsense, and notes that this one rises above that level. | |
| Dec 20, 2021 at 13:33 | comment | added | Aryaan | @Armadillo I actually wanted approximate answers, and that website really helps thanks a lot | |
| Dec 20, 2021 at 13:00 | comment | added | David Hammen | @Armadillo That's rather cool, and in Javascript no less. However, at some point, anyone interested in space exploration needs to know how to program. | |
| Dec 20, 2021 at 12:44 | comment | added | Armadillo | @Ryan here is a simple online tool you can use to generate porkchop plots - though note that this is only approximate: sdg.aero.upm.es/index.php/online-apps/porkchop-plot | |
| Dec 20, 2021 at 12:39 | comment | added | David Hammen | I stopped watching the video at about the four minute mark based on excess spewed nonsense. Hohmann transfers are not used to get spacecraft to Mars. What is used is a solution to Lambert's problem, but then one needs a solution that makes sense. There are multiple questions and answers on this site that ask about pork chop plots (or porkchop plots), and also on the physics and astronomy sister sites. Unfortunately, developing those plots is computationally expensive, so you are not going to find an online tool that does that. Fortunately, python is more than capable of doing just that. | |
| Dec 20, 2021 at 12:26 | comment | added | BrendanLuke15 | Some texts refer to this as 'the Gauss Problem' (specifically "Fundamentals of Astrodynamics" by Bate, Mueller, & White (1971) | |
| Dec 20, 2021 at 7:20 | comment | added | Aryaan | @AlfonsoGonzalez Is there an online calculator as such to make these calculations? | |
| Dec 20, 2021 at 2:08 | comment | added | Alfonso Gonzalez | I think you're looking for Lambert's problem. Given two position vectors and a time of flight, a Lamberts solver will give you the velocity vectors at the two position vectors | |
