Quick note- Space is a one week summer program, UAS (the RPA one) is two weeks, and there's also a one-week cyber summer program. Jump is two weeks and soaring is three. Basically, you can get some combination of these programs during your 3 week airmanship summer period-or, you could end up with extra weeks of "support." So, you could end up with jump and space, jump and cyber, cyber and UAS, UAS and support, cyber and support, etc. You won't get another program or support if you do soaring, however, since you'll belong to the soaring program all three weeks.
I did space and jump last summer-I found jump to be a lot more exciting, but space is a decent program too. Last year we visited active duty space officers on a local base, did some hands-on activities, and got a chance to earn space wings in the USAFA FalconSAT program.
I didn't do UAS, but it's basically two weeks of learning how to use all the systems and get certified through that program as well. There's a school-year version of UAS training you can do if you're interested.
