NASA's Lucy spacecraft is getting ready for its close flyby of asteroid Dinkinesh tomorrow, Nov 1, at 12:54 EDT. science.nasa.gov/...
Asteroid Dinkinesh is about 760 m wide; it is part of the main belt of asteroids located between the orbits of Mars and Jupiter.
Lucy will use this encounter to test its instruments and tracking systems, in preparation for its main mission of surveying 7 Jupiter trojan asteroids in 2027-2033.
The Lucy mission is named after the Lucy hominin fossils, which were discovered in 1974 in Ethiopia.
Dinkinesh is the Ethiopian name for the Lucy fossil. The name means "you are wonderful" in the Amharic language.
Asteroid (52246) Donaldjohanson is named after one of the co-discoverers of the Lucy fossil.
The names for these two asteroids were recommended by the Lucy team.
The Lucy hominid was named after the 1967 Beatles song "Lucy in the Sky with Diamonds". The song was played loudly and repeatedly in the expedition camp all evening after the excavation team's first day of work on the recovery site.
The Lucy spacecraft carries a disc made of lab-grown diamonds for its L'TES instrument.
Let's listen to the Beatles as Lucy flies by 'You are wonderful' Dinkinesh.
Now let’s send our minds soaring to solve today’s chess puzzle composed by Comins Mansfield, the well-known British composer of Two Move Chess problems, in 1974, the year the Lucy hominin specimen was discovered.
P.S.
The chess puzzle is published on Sundays, Tuesdays and Thursdays.
It is customary for advanced players to wait till midnight ET before posting the full solution. Before then, they provide some stats about the solution (e.g., the minimum number of distinct checkmate moves), help guide others, and sometimes post hints. But there are no hard-and-fast rules; feel free to post comments as you please.
