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.
