Walkabout the Galaxy
Dr. Humberto Campins
Astrophysics and Astronomy | Physics
Join us for a behind-the-scenes blow-by-blow discussion of the activities of NASA's OSIRIS-REx mission as it made contact with the asteroid Bennu and captured a sample of material from the ancient solar system. We are joined by Dr. Humberto Campins, a Co-Investigator on the mission, for an in-depth examination of this literally ground-breaking event. And we also have a Halloween-theme for our trivia, space news, and a nerd news apology.
You may know me as Phosphane, but either way, I'm just a phosphorus and three hydrogen atoms hanging tight. You've got your OH2, or H2O, as you odd humans like to call it, your NH3 and CH4, boring. Like CH4, phosphene, PH3 is spontaneously flammable and odorless when pure, but add my stinky cousin diphosphene if you're a fan of rotting fish. Remember that spontaneous combustion? That's why you won't be finding me, or methane, in atmospheres with a bunch of spare oxygen (Venus) unless you've got some major life activities to replenish the phosphene (Earth). Phosphene, if you think you found me on Venus, good luck. Phosphene, good luck (Uzbekistan Airways).
