Could have gone in the robotic section, but putting it here.

Nice.

Excellent meaty article Chris! :)
-
I'll say more than just posting nice or I would have just liked the article, which I've done anyway, although I thought it was a nice angle to take with the unmanned spacecraft as they seem massively more interesting than playing with a boulder. DART watched by AIM is cool!

Great article.
However some parts are a little confusing... ???
-> “In addition, DART’s shifting of Didymoon’s orbit will mark the first time humanity has altered the Solar System."
My comment: This is a very strange (and wrong) statement in so many ways.
-> A hands on examination of an asteroid will occur in the mid-2020s, when the crew of Exploration Mission -2 (EM-2) conduct an EVA from their Orion spacecraft.
My comment: The fact that the manned ARM mission will not happen in 2020/2021 directly rules out that EM-2 will visit the ARM robotic mission. EM-2 has been multiple times confirmed to be launching in 2020/2021. Solutions: The EM-2 mission will either last ~4 years or EM-2 and EM-4/5 will change call names, both solutions sound rather unlikely.

The first is a quote. The second is about EM-2 scenarios already covered in the article that's embedded into the paragraph you read. It is currently called EM-2, but it won't be the second mission.

That's the reference material (the update being Option B was selected).

Another good article.
I do have one question, though. Is/Are AIDA actual, approved, funded missions? Everything I can find (My Google-fu may be weak) puts them at the Study/Proposal/Pre-Phase A level.
-
I guess this goes here:
EM-1 will have multiple Secondary Payloads with the first SP confirmed as the NEA Scout Cubesat (6U with deployable solar arrays and solar sail.). The full name of the Secondary Payload #1 is the Near Earth Asteroid Scout cubesat

This video shows the launch of Exploration Mission-1 and location of the secondary payloads in the Space Launch System's adapter ring. Also shown is the deployment of the NEA Scout cubesat and its asteroid rendezvous.

Or, you know, EM-2 will slip or won't be manned.

The Enhanced Gravity Tractor demo for ARM Option B will be "playing" (i.e demonstrating diversion) with an asteroid big enough to destroy Switzerland (400m across, bigger than Apophis) in a massive explosion and cause enormous tsunamis, devastating coastal areas all over the Pacific.
