Dr Ciaccio (not a doctor) looks forward to the landing of the NASA Mars Rover Perseverance and Ingenuity Helicopter Drone which is scheduled for this Thursday 18 Feb 2021 at 11:15am PST. Right now coders and mathematicians are sweating the landing which is complex, dangerous and completely hands-off. Basically they'll be shitting their pants for 7 minutes while the thing lands itself, or doesn't.
