Topic: Trojan Asteroids
The Systems Integration Review ensured segments, components, and subsystems, scientific instrumentation, electrical and communication systems, and navigation systems are on schedule to be integrated into the system. It confirmed that facilities, support personnel, and plans and procedures are on schedule to support integration. ![]() NASA’s Lucy spacecraft poses in front of the orbit trajectory for her 12-year mission to study the Trojan Asteroids. Lucy will be featured in her own cartoon series coming soon. (NASA’s Goddard Space Flight Center) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Lucy Mission discovers asteroid Eurybates has a Satellite
Launching in October 2021, Lucy will be the first space mission to study the Trojan asteroids, a population of small bodies orbiting the Sun “leading” and “trailing” Jupiter, at the same distance from the Sun as the gas giant. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Lucy Mission completes Critcal Design Review
During this review, Lucy team members presented the completed mission design, demonstrating that the team has met all the technical challenges of the mission and is ready to begin building hardware. After the review completion, NASA’s independent review board provided a green light for proceeding into the fabrication/manufacturing stage of the mission. «Read the rest of this article» Sections: Technology | No Comments
NASA Lucy Spacecraft to navigate to Jupiter’s Trojan AsteroidsWritten by Tamsyn Brann
In 2021, the feat of navigation that is the Lucy mission will launch. To steer Lucy towards its targets doesn’t simply involve programming a map into a spacecraft and giving it gas money – it will fly by six asteroid targets, each in different orbits, over the course of 12 years. ![]() This diagram illustrates Lucy’s orbital path. The spacecraft’s path (green) is shown in a frame of reference where Jupiter remains stationary, giving the trajectory its pretzel-like shape. After launch in October 2021, Lucy has two close Earth flybys before encountering its Trojan targets. In the L4 cloud Lucy will fly by (3548) Eurybates (white), (15094) Polymele (pink), (11351) Leucus (red), and (21900) Orus (red) from 2027-2028. After diving past Earth again Lucy will visit the L5 cloud and encounter the (617) Patroclus-Menoetius binary (pink) in 2033.

NASA’s Lucy Spacecraft to explore Jupiter Trojan AsteroidsNASA’s Goddard Space Flight Center
Most of these leftover objects were then lost, as shifts in the orbits of the giant planets scattered them to the distant outer reaches of the solar system or beyond. But some were captured in two less-distant regions, near points where the gravitational influence of Jupiter and the Sun balance, and have remained trapped there, mostly untouched, for billions of years. «Read the rest of this article» Sections: Technology | No Comments
NASA explains why it’s important to study Space RocksNASA’s Jet Propulsion Laboratory
Those clues come in the form of asteroids, comets and other small objects. Like detectives sifting through forensic evidence, scientists carefully examine these small bodies for insights about our origins. ![]() The small worlds of our solar system help us trace its history and evolution, including comets.

NASA L’Ralph instrument to study Trojan Asteroids aboard Lucy SpacecraftWritten by Tamsyn Brann
Ralph, however, is not an impossibly accomplished astronaut — it is a scientific instrument that has made many discoveries since it first launched aboard the New Horizons spacecraft in 2006. Given a name and not an acronym, Ralph enables the study of the composition and atmospheres of celestial objects. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Discovery Program to send missions to Jupiter’s Trojan Asteroids and Metal AsteroidWritten by DC Agle
“Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids, while Psyche will study a unique metal asteroid that’s never been visited before,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “This is what Discovery Program missions are all about – boldly going to places we’ve never been to enable groundbreaking science.” ![]() Artist’s concept of the Psyche spacecraft, which will conduct a direct exploration of an asteroid thought to be a stripped planetary core.

NASA picks Five Science Projects to be considered for Future MissionsWritten by DC Agle
The submitted proposals would study Venus, near-Earth objects and a variety of asteroids. Each investigation team will receive $3 million to conduct concept design studies and analyses. After a detailed review and evaluation of the concept studies, NASA will make the final selections by September 2016 for continued development leading up to launch. ![]() Artist’s concept of the Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy (Veritas) spacecraft, a proposed mission for NASA’s Discovery program.

NASA’s Wide-field Infrared Survey Explorer (WISE) makes discovery about the Trojan asteroids in the same orbit as Jupiter around the SunWritten by Whitney Clavin
The observations are the first to get a detailed look at the Trojans’ colors: both the leading and trailing packs are made up of predominantly dark, reddish rocks with a matte, non-reflecting surface. What’s more, the data verify the previous suspicion that the leading pack of Trojans outnumbers the trailing bunch. ![]() New results from NASA’s Wide-field Infrared Explorer, or WISE, reveal that the Jovian Trojans — asteroids that lap the sun in the same orbit as Jupiter — are uniformly dark with a hint of burgundy color, and have matte surfaces that reflect little sunlight.
