It would be easier to grow one crop instead of many, and if we have to pick one, GMO soybeans would be the logical start. An already complete protein source, we could modify them a bit to balance out the nutrients and help with zero gravity growing.

Reducing the types of crop is good having only 1 can lead to a few problems 1 astronaut's getting bored with same thing day in day out
2 if the crop gets ill then there is no alternate food for the nauts to eat. so I think having 4-6 crops would be better.

We should have redundancy on every thing. Also food sources. So at least two that gives protein and so on.

Also we may want seeds to test what plants can grow well in space.

I think as many crops as possible (which require about the same care + nutrients) would be most effective in reducing the risk of a loss of a food source. Green plants could provide oxygen and water as well, although making it completely self-sustainable would require a massive operation, increasing launch costs.

if we made like a super space station that orbited Jupiter (in a low radiation level) then we could increase everything and have less risk time when lading/drilling into europa.

So, in fact creating a type of Bio-Sphere inside a space-station that orbits Jupiter. Perhaps a mini-version of a biosphere capable of sustaining "earth-like" conditions (inside the sphere) on board of the manned spacecraft might be an idea however, it can ofcourse come up with complications ofcourse. (I'm just throwing ideas here).

What other crops would you all suggest?

Well we could have a virtually huge number of crop species and varieties by carrying a seedbank of relatively lightweight and small seeds/propagules. We may only grow 6-20 species at any time, but we can keep variety up by accessing our local seedbank. I think we should try to have at least 100 crops in storage to keep moral up, that way we could include niche pleasantries such as spices, coffee, tea, chocolate, medicinal plants, as well as a wide variety of crop species. Crops on board of the ship may be limited, but on the surface of Europa we will want many of these to keep us sane.

Long term, having a coffee tree on Europa would be nice. Maybe decades down the road. I, for one, do not make it long here on Earth without my coffee.

A seed bank is an interesting idea, however, it would be purely experimental for the explorers, and wouldn't be a great idea to base their overall nutrition on. First, without extensive studies, it would be difficult to see what would grow. If we picked only one or two species, we could test them before we left. Second, many of the plants you mentioned have a long grow time before harvest. If growing crops is part of the mission, they will need food that can be harvested in months.

Let me propose two different questions. First: how much pre-packed food can they take and how long will it last? Second, what can the explorers do immediately to make sure they do not starve when the food runs out?
