Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • Some participants share links to upcoming SpaceX launches and express interest in following the events.
  • There is mention of a digital tape recovered from the Columbia crash that contains footage of reentry plasma flashes, with requests for information on where to view it.
  • Discussion includes a write-up on the K2 mission and its discoveries regarding exoplanets.
  • Participants highlight the significance of NASA's Juno mission to Jupiter, which aims to study the Great Red Spot and its heat dynamics.
  • There is mention of an anomaly in star formation related to the object CX330, which is located in a star-forming region but lacks the typical surrounding gas and dust.
  • Some participants express optimism about government cooperation with private industries in advancing space technology.
  • Information is shared regarding Io's fluctuating atmosphere and the TESS mission's goals in exoplanet exploration.

Areas of Agreement / Disagreement

The abort system might do that (with some rounding errors), but the rocket will certainly not. Net acceleration at liftoff is only something like 0.4 g.

Fueling of Artemis II has started, 9 hours and 50 minutes to go. I started a thread.

Ehh? I don' think so, that's more than 12 g's including the one they already have. I'm not sure where they get that, but it's in the google ai result. Chicken or egg...
That article now contains a more realistic acceleration (around speed of sound after a minute) and the following at the end:
Correction: A previous version of this story misstated the initial liftoff speed of the rocket.
