Звали Брюса Виллиса на запуск, но он не приедет :(

ЦитатаIn an interview, NASA Administrator Bill Nelson said the agency invited Bruce Willis to the launch of the asteroid redirect mission because of his role in "Armageddon." Nelson said he's not going but "we didn't want to miss that connection."

SpaceX's Falcon 9 rocket with NASA's DART asteroid deflection experiment is standing on a launch pad at Vandenberg Space Force Base, California.
The mission has an instantaneous launch opportunity tonight at 10:21:02 pm PST (1:21:02 am EST; 0621:02 GMT).

Rocket @NASA & @SpaceX are completing key milestones for the #DARTmission!
Last week, the DART spacecraft was encapsulated inside the payload fairings that will protect it during launch atop a #Falcon9 and teams completed a successful Flight Readiness Review: http://go.nasa.gov/3FEWPGk

Hmm.  0.5 tonne at 6 km/s with perfect coupling of momentum to a 1 megaton asteroid should be a delta-V of 3 mm/s .  Orbital velocity of Didymoon is (2 pi 1.2 km / 12 hr ) = 150 mm/s so it's a 2% change in the period (to cosmologist accuracy) and indeed of order 10 min

Didymoon ускорится или замедлится относительно Dimorphos? Кстати хорошая оценка массы для Didymoon.

Уменьшится, как оказалось
