Since the last installment of the subject commentary more than two years ago, Lucy performed her second Earth gravity assist (EGA-2) in late 2024 and a flyby of asteroid Donaldjohanson on 20 April 2025.  These most recent events are detailed beginning on p. 7 of the attached “R3” PDF file.  Minor edits, chiefly motivated by nomenclature consistency, also appear earlier in R3.  Unless unforeseen events arise, expect R4 to be coming your way after Lucy’s first Trojan asteroid flyby at 3548 Eurybates (1973 SO) on 11 August 2027.

I may not live long enough to tell the complete story of Lucy’s mission to the Jupiter Trojan asteroids, but you’ll find attached the second installment.  This makes minor editorial changes to the account of Lucy’s Earth departure published last November.  It then appends information on the mission’s first Earth flyby this October 16 and illustrates its two-year trip around the Sun before Earth will be encountered a second time.  Enjoy!

Attached is a short account of the Lucy mission's launch last month.  This narrative is accompanied by trajectory plots through 2022 as the spacecraft begins its journey to explore Trojan asteroids in Jupiter's heliocentric orbit.  Questions and comments are, as always, welcome.
