How to Watch The Launch of Lucy, a NASA Probe Set to Visit Jupiter’s Trojan Asteroids

An early morning launch is planned 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 time in Lucy’s 21-day launch window, and current weather conditions show a 90 percent chance of favorable conditions for liftoff from Cape Canaveral Space Force Station in Florida. The launch window remains open for 75 minutes.

Lucy will embark on a 12-year mission to locate the “fossils of planet formation,” the Trojan asteroid swarm of Jupiter. This mission provides the first opportunity to take a closer look at these intriguing objects.

Lucy, named after a fossil human ancestor, “Lucy,” whose skeleton offers unique insight into the evolution of humanity—will be the first spacecraft to visit 8 different objects.

Before turning to Trojan asteroids, it will study a main-belt asteroid. Scientists hope the Lucy mission will revolutionize our knowledge of the origins of planets and the formation of the solar system.

16 launch coverage begins at 5 a.m. EDT on various platforms: the countdown commentary and launch broadcast will air on NASA Television and the agency’s website as well as on YouTube. Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV and NASA’s app.

The Trojan asteroids, which borrow their name from Greek mythology, orbit the Sun in two swarms – one ahead of Jupiter and the other swarm behind it.

Trojans are “held there by the gravitational effects of Jupiter and the Sun, so if you put an object early in the history of the Solar System, it’s been frozen forever,” said Hal Levison, principal investigator of the Lucy mission. ” Press conference on 13 October. “These things are actually fossils from which the planets formed.”

Both the fossil and the mission are a tribute to the Beatles’ tune “Lucy in the Sky with Diamonds” and you can see that the Lucy Mission logo is shaped like a diamond.

In 12 years, Lucy will travel about 4 billion miles (6.4 billion kilometers) at a speed of about 400,000 mph (17,881.6 meters per second).

The seven Trojan asteroids that Lucy will visit are all named after Homer’s heroes. Iliad: Eurybates, Quetta, Polymel, Lucas, Orus, Patroclus. But the first asteroid flyby will take place in 2025, as the spacecraft tours the asteroid belt between Mars and Jupiter, flying past an asteroid named (52246) Donaldjohansson, named after the discoverer of the famous Lucy fossil skeleton.
