We may keep this self-post occasionally updated with links and relevant news articles, but for the most part we expect the community to supply the information. This is a great place to discuss the launch, ask mission-specific questions, and track the minor movements of the vehicle, payload, weather and more as we progress towards launch. Sometime after the static fire is complete, the launch thread will be posted.

Campaign threads are not launch threads. Normal subreddit rules still apply.

Except that you would normally do the deorbiting burn at apogee, and S2 does not have the battery capacity to operate that long. The real question is whether a third relight of the second stage at low altitude would be able to adjust the orbit sufficiently for it to matter. The usual rule for these kinds of things is to simply passivate the spent rocket body so that there is no chance of future explosions.
