YES SUCCESS, or Qapla I've been waiting for this and hoping nothing would go wrong Seems some prayers ARE answered. I can't wait until they do the Richest Field look. It seems we might be able to see the Big Bang itself this time

Yes, I think "first light" is the real measure. However, it's certainly nice to see it not blow up in a cataclysmic fireball!!
Nothing is ever 100% safe. I'm hoping the NASA team gets excited about images taken during calibration, etc. Waiting until June or whenever is ... unfortunate!
