Obligatory new thread for the Lucy mission, now that it has been selected by NASA to launch as Discovery mission 13! Lucy will launch in 2021, and will perform a flyby of a main belt asteroid in 2025, before making flybys of at least six Jupiter trojans from 2027 to 2033. The mission, led by the Southwest Research Institute and Principal Investigator Harold F. Levison, will send a spacecraft carrying updated versions of New Horizons' LORRI and RALPH instruments.

Note for the new members: Generally speaking, please consult a member of the admin/mod team before creating new topics. Not a hard rule, but it does help to keep the place tidy.

Lucy launch is only 2 days away. We are now powered for the last time and this AM moved to the pad at LC41 and looking at a nice early AM launch on 10/16 (0934 UTC, 0534 EDT) with great weather forecasat. Hope everyone is going to get up early with us for launch. There was a very good pre-launch press briefing yesterday that is on YouTube (sorry for all the commercials I could not find any alternate hosting sites,YouTube video link). Hope you have a chance to watch the launch live (or after getting up for those in the US). I have seen some questions on forums such as reddit asking what propulsion elements Lucy has (All of the following info is not export controlled so I can provide these answers here). We have eight 1 N and six 22 N mono-propellant thrusters for ACS and the majority of the trajectory correction maneuvers (up to 50 m/sec). For larger burns we have a 470 N bi-propellant main engine (Leros 1C). The propellants are hydrazine and dinitrogen tetroxide. There are currently 4 burns over 7 years that will use our main engine. We won't need to use that engine till mid 2024 (large DSM to target Earth for an Earth flyby). Go Lucy!!!
