Lucy Fact Sheet First to Visit Lucy Jupiter’s Trojan Asteroids Lucy and Lockheed Martin LOCKHEED MARTIN’S NEXT ASTEROID-HUNTING SPACECRAFT Lucy is NASA’s mission that will take an epic 12-year, 4-billion-mile journey to Jupiter’s elusive Credit: NASA Trojan asteroids. Scientists believe the Trojan asteroids are relatively unblemished remnants from the creation of our solar system and could hold clues about how it formed. As a crucial member of the mission team, Lockheed Martin Space designed, built, integrated, tested and will operate Lucy after the spacecraft launches in fall 2021. At Lockheed Martin Space, we combine our long history of supporting planetary exploration with new digital engineering innovations to help our customers discover more than they ever thought possible. Lucy is the seventh of 13 NASA Discovery Program missions Lockheed Martin has supported. This mission builds on years of technology from previous spacecraft the team has built, like Mars Odyssey, OSIRIS-REx and InSight, among others.

  • Solar System Exploration
    Theme: Solar System Exploration Cassini, a robotic spacecraft launched in 1997 by NASA, is close enough now to resolve many rings and moons of its destination planet: Saturn. The spacecraft has now closed to within a single Earth-Sun separation from the ringed giant. In November 2003, Cassini snapped the contrast-enhanced color composite pictured above. Many features of Saturn's rings and cloud-tops now show considerable detail. When arriving at Saturn in July 2004, the Cassini orbiter will begin to circle and study the Saturnian system. Several months later, a probe named Huygens will separate and attempt to land on the surface of Titan. Solar System Exploration MAJOR EVENTS IN FY 2005 Deep Impact will launch in December 2004. The spacecraft will release a small (820 lbs.) Impactor directly into the path of comet Tempel 1 in July 2005. The resulting collision is expected to produce a small impact crater on the surface of the comet's nucleus, enabling scientists to investigate the composition of the comet's interior. Onboard the Cassini orbiter is a 703-pound scientific probe called Huygens that will be released in December 2004, beginning a 22-day coast phase toward Titan, Saturn's largest moon; Huygens will reach Titan's surface in January 2005. ESA 2-1 Theme: Solar System Exploration OVERVIEW The exploration of the solar system is a major component of the President's vision of NASA's future. Our cosmic "neighborhood" will first be scouted by robotic trailblazers pursuing answers to key questions about the diverse environments of the planets, comets, asteroids, and other bodies in our solar system.

Powell | Published: Monday, January 4, 2021 Whatever craziness may be happening on Earth, the coming year promises to be a spectacular one across the solar system. 2020 - It was the worst of times, it was the best of times. First landing on the lunar farside, two impressive successes in gathering samples from asteroids, the first new pieces of the Moon brought home in 44 years, close-up explorations of the Sun, and major advances in low-cost reusable rockets. First Visit to Jupiter's Trojan Asteroids First Visit to Jupiter's Trojan Asteroids In October, NASA is set to launch the Lucy spacecraft. Over its 12-year primary mission, Lucy will visit eight different asteroids. One target lies in the asteroid belt. The other seven are so-called Trojan asteroids that share an orbit with Jupiter, trapped in points of stability 60 degrees ahead of or behind the planet as it goes around the sun. These objects have been trapped in their locations for billions of years, probably since the time of the formation of the solar system. They contain preserved samples of water-rich and carbon-rich material in the outer solar system; some of that material formed Jupiter, while other bits moved inward to contribute to Earth's life-sustaining composition. As a whimsical aside: When meteorites strike carbon-rich asteroids, they create tiny carbon crystals.

Fermi 5, 50125, Firenze, Italy Received 15 December 2017 / Accepted 7 August 2018 ABSTRACT Aims. The goal of this investigation is to determine the origin and surface composition of the asteroid (121514) 1999 UJ7, the only currently known L4 Martian Trojan asteroid. Methods. We have obtained visible reflectance spectra and photometry of 1999 UJ7 and compared the spectroscopic results with the spectra of a number of taxonomic classes and subclasses. A light curve was obtained and analysed to determine the asteroid spin state. Results. The visible spectrum of 1999 UJ7 exhibits a negative slope in the blue region and the presence of a wide and deep absorption feature centred around ∼0.65 µm. The overall morphology of the spectrum seems to suggest a C-complex taxonomy. The photometric behaviour is fairly complex. The light curve shows a primary period of 1.936 d, but this is derived using only a subset of the photometric data.

  • Origin and Evolution of Trojan Asteroids 725
    Marzari et al.: Origin and Evolution of Trojan Asteroids 725 Origin and Evolution of Trojan Asteroids F. Marzari University of Padova, Italy H. Scholl Observatoire de Nice, France C. Murray University of London, England C. Lagerkvist Uppsala Astronomical Observatory, Sweden The regions around the L4 and L5 Lagrangian points of Jupiter are populated by two large swarms of asteroids called the Trojans. They may be as numerous as the main-belt asteroids and their dynamics is peculiar, involving a 1:1 resonance with Jupiter. Their origin probably dates back to the formation of Jupiter: the Trojan precursors were planetesimals orbiting close to the growing planet. Different mechanisms, including the mass growth of Jupiter, collisional diffusion, and gas drag friction, contributed to the capture of planetesimals in stable Trojan orbits before the final dispersal. The subsequent evolution of Trojan asteroids is the outcome of the joint action of different physical processes involving dynamical diffusion and excitation and collisional evolution. As a result, the present population is possibly different in both orbital and size distribution from the primordial one. No other significant population of Trojan aster- oids have been found so far around other planets, apart from six Trojans of Mars, whose origin and evolution are probably very different from the Trojans of Jupiter. 1.
