How to watch the launch of Lucy, a NASA probe set up to visit Jupiter’s Trojan asteroids – .


An early morning launch is scheduled for the Lucy spacecraft, the first space mission to study Jupiter’s Trojan asteroids.

Tomorrow, October 16 at 5:34 a.m. EDT is the first day and hour of Lucy’s 21-day launch window, and current weather conditions show a 90% chance of a favorable take-off from the space station in Cape Canaveral in Florida. The launch window remains open for 75 minutes.

Lucy will embark on a 12-year mission to explore the “fossils of the formation of the planets,” the Trojan asteroid swarms of Jupiter. This mission offers the first opportunity to observe these intriguing objects up close.

Lucy, named after the fossilized human ancestor ‘Lucy’, whose skeleton has provided unique insight into the evolution of mankind – will be the first spacecraft to visit 8 different objects.

Before heading to the Trojan asteroids, he will study an asteroid in the main belt. Scientists hope the Lucy mission will revolutionize our knowledge of planetary origins and how the solar system was formed.

Coverage of the October 16 launch begins at 5 a.m. EDT on various platforms: Countdown commentary and the launch airing will air on NASA Television and the agency’s website, as well as YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV et l’application de la NASA.

Trojan asteroids, which borrow their name from Greek mythology, orbit the sun in two swarms – one in front of Jupiter and a second swarm behind it.

Trojans “are held there by the gravitational effect of Jupiter and the sun, so if you put an object in there early in the history of the solar system, it’s stable forever,” said Hal Levison, the principal investigator of the Lucy mission, at a press conference on October 13. “These things are really the fossils of what the planets were formed from. ”

Both the Fossil and the Mission are a tribute to the Beatles song “Lucy in the Sky With Diamonds”, and you can see that the Lucy Mission logo is shaped like a diamond.

Over 12 years, Lucy will travel nearly 4 billion miles (6.4 billion kilometers) at approximately 400,000 miles per hour (17,881.6 meters per second).

The seven Trojan asteroids that Lucy will visit are all named after Homer’s heroes The Iliad: Eurybates, Queta, Polymele, Leucus, Orus, Patroclus. But the first asteroid flyby will take place in 2025, when the spacecraft will visit the asteroid belt between Mars and Jupiter, passing an asteroid named (52246) Donaldjohanson, named after the discoverer of Lucy’s famous fossilized skeleton.
