Today is #AsteroidDay — the dinosaurs 🦖 didn’t have a planetary defense program. We do. #Chelyabinsk & #Tunguska prove #citykiller #asteroid impacts still happen. Somewhere out there is a continental-killer with our name on it. 🧪🔭 #LookUp #DART

Working in teams of 3, 36 groups of @SSPers picked a NEA to observe & have been tracking it for ~3weeks now. Once their data is reduced, they will perform photometry/astrometry to get brightness/position. Using python code they wrote, they will determine its orbit. #AsteroidDay

@NASAJPL’s #CNEOS counts 29,131 near-Earth asteroids, 852 that are >1km in size & would cause catastrophic damage if it hit Earth. This summer I’m an academic director @SSPers where talented HS students in STEM are tasked with observing a NEA & determining its orbit. #AsteroidDay

It’s not a question of *if* but a question of *when*. Somewhere out there is a big piece of rock with our address on it. 114 years ago, Tunguska happened where 80M trees were flattened b/c of a 220M-pound rock. 9 years ago, we were caught by surprise in Chelyabinsk. #AsteroidDay

Happy #AsteroidDay, everybody! It's the annual, official UN-proclaimed observance of the Tunguska impact and awareness-raising about the asteroid impact hazard!
I'll be having cake, per local tradition, and attending an afternoon of asteroid-related fun (a talk and some science mingling).

Real space observation requires incredible systems precision, a logic I carried over from my 4 decades in IT into the core mechanics of the novel. Celebrate #asteroidday by exploring a new universe over at www.thefarthest.ca! #thefarthest #hardscifi
