Astronomers and skywatchers are sharing their photographs and movies of Nasa’s Lucy spacecraft because it buzzed shut by Earth on Sunday.
The massive massive faculty bus-sized Lucy spacecraft handed inside 220 miles of Earth Sunday morning, and was seen to viewers in Western Australia and the western US. Lucy’s flyby got here on the one-year anniversary of its launch, the primary high-speed shut encounter of a deliberate 12-year mission to go to the Jupiter Trojan asteroids.
Nasa inspired folks to share photographs of Lucy on social media utilizing the hashtag #SpotTheSpacecraft, or photographs of themselves waving on the passing Lucy utilizing the hashtag #WaveToLucy.
Members of the Lucy mission crew based mostly on Colorado needed to drive to Nebraska to get out from below cloud cowl with a purpose to seize the video of Lucy streaking overheard that they then shared on the social media web site Twitter.
Pluto researcher Marc Buie took a picture of Lucy that was shared by French space-blog Twitter account @RevesdEspace, whereas the Virtual Telescope Project, a world robotic telescope cooperative, also capture Lucy images.
Nasa’s Goddard Space Flight Center, in the meantime, has shared animations on Twitter illustrating Lucy’s Earth flyby and subsequent mission, whereas highlighting the spacecrafts distinctive, round photo voltaic panels, every 24 ft in diameter — massive sufficient to produce Lucy with the five hundred watts of energy the spacecraft will want whereas touring by the darkish reaches of area among the many asteroids close to Jupiter.
Launched from Kennedy Space Center, in Florida, on 16 October 202, Lucy is Nasa’s first mission to the Trojan asteroids of Jupiter, two massive populations of area rocks that share the fuel large’s orbit, however precede and observe the planet by 60 levels alongside that orbit.
Sunday’s flyby of Earth gave Lucy added momentum, slingshotting the spacecraft out towards the orbit of Mars, a maneuver often known as a gravity help. Lucy will make one other gravity help move by Earth in 2024 earlier than lastly heading out towards its first targets.
The spacecraft will first fly by an asteroid often known as Donaldjohanson in the primary asteroid belt in 2025, an area rock that’s not a Jupiter Trojan, however is conveniently situated alongside the way in which.
Lucy will then attain the main inhabitants of Jupiter Trojans in 2027, flying by 4 area rocks, Eurybates, Polymele, Leucus, and Orus, every named for characters within the Homeric epic The Iliad.
Lucy will then head again to Earth for one more gravity help flyby of our planet in 2031, which is able to put the spacecraft on a course to go to the trailing inhabitants of Jupiter Trojans in 2033, visiting the binary pair of asteroids Patroclus and Menoetius, which orbit one another at simply 400 miles aside.
Seen from above, Lucy’s flight path seems to be like a determine eight knotted up like a pretzel, in response to Nasa.
You can observe Lucy’s present trajectory and watch an animation exhibiting its future movement relative to Earth, it’s asteroid targets, and the planet Jupiter however going to Nasa’s whereislucy.area web site.
