Having some Eve problems


Recommended Posts

AG,

I don't have B9 aerospace, but that shouldn't matter since the physics are the same.

A little more info?

Could you describe the mission package, flight plan, and exactly what's wrong?

Best,

Well, first I don't know if I need one rocket or multiple. Second I don't know where Eve should be and third how to get enough Delta V

Heh - I think your title sums up most players thoughts once they get to a certain point in this game. Speaking personally, the only things I've sent to Eve have been orbiters. I haven't ever tried to land anything, still less return anything, so I don't know how much delta-V is required other than "a honking great pile", which isn't terribly helpful.

For getting there - or any other planet for that matter - Alexmoon's calculator is your friend. You can use it figure out what in-game time is best to set off for any of the planets. Much easier than worrying about phase angles and stuff.

Ah!

So basically, you haven't started attempting it yet.

It's going to take a minimum of 5,800 m/sec to get you to Eve on a 1 way trip from the pad (1,300 from low orbit).

This is strictly 1 way with aerobraking at the other end.

Phase angle should be -54*. That is, Eve is trailing Kerbin by 54* in their orbits around Kerbol.

AFA how to design a ship to get the required DV budget and all the technical stuff you need to know (there's a lot), it's all up in the tutorial section.

Free advice: A round trip to Eve and back is about the most difficult undertaking in KSP. I'd recommend saving that for last, after you've got enough other trips under your belt. You really need to learn to crawl before attempting to win a gold medal in the olympics!

Best,

Seems like you need a phase angle diagram:

Also, this link may come in handy rather sooner than later (give it a try!):

That's for getting to Eve. If you want to return from Eve's surface, it will probably require the biggest rocket you ever built. Have a look at Eve Rocks over in the Challenges subforum. That's the go-to place to discuss nitty-gritty particulars; and a quick glance will give you a general idea of the scope of this undertaking.
