☆ NASA Lucy mission: A space rock got a moon after sun-driven quake

CNN —Astronomers were in for a surprise when NASA’s Lucy mission flew by an asteroid named Dinkinesh in November and spotted a contact binary — two smaller space rocks that touch each other — orbiting the asteroid like a moon. “Basically, the planets formed when zillions of smaller objects orbiting the Sun, like asteroids, ran into each other. The Lucy mission captured additional imagery revealing that the asteroid Dinkinesh’s moon is actually two space rocks that are touching one another. Too distant to be seen in detail with telescopes, the asteroids will get their close-up when Lucy reaches the Trojans in 2027. The mission borrows its name from the Lucy fossil, the remains of an ancient human ancestor discovered in Ethiopia in 1974.

☆ Asteroid visited by NASA spacecraft has a ‘puzzling’ companion

CNN —Dinkinesh, a small asteroid that NASA’s Lucy mission visited last week, continues to surprise. At first, images suggested that the space rock was part of a binary pair, with a smaller asteroid orbiting Dinkinesh. The first image taken by the spacecraft during its closest approach revealed the companion, but not the fact that it was a contact binary. “Contact binaries seem to be fairly common in the solar system,” said John Spencer, Lucy deputy project scientist at the Southwest Research Institute, in a statement. The skeleton has helped researchers piece together aspects of human evolution, and NASA Lucy team members hope their mission will achieve a similar feat regarding the history of our solar system.

CAPE CANAVERAL, Fla. (AP) — The little asteroid visited by NASA’s Lucy spacecraft this week had a big surprise for scientists. It turns out that the asteroid Dinkinesh has a dinky sidekick — a mini moon. The discovery was made during Wednesday’s flyby of Dinkinesh, 300 million miles (480 million kilometers) away in the main asteroid belt beyond Mars. In data and images beamed back to Earth, the spacecraft confirmed that Dinkinesh is barely a half-mile (790 meters) across. NASA sent Lucy past Dinkinesh as a rehearsal for the bigger, more mysterious asteroids out near Jupiter.

☆ NASA sent a spaceship rocketing by an asteroid — and discovered the space rock has a little baby one dancing around it

NASA sent a spacecraft flying by the Dinkinesh asteroid. The agency discovered that Dinkinesh is actually a binary asteroid system. The Lucy spacecraft discovered that the larger asteroid has a baby asteroid dancing around it. But the Lucy spacecraft returned images showing that the asteroid Dinkinesh is actually a binary asteroid system, meaning there are two asteroids orbiting a common center. Lucy flew by the asteroid system at a speed of 10,000 miles per hour, NASA said.

CNN —When NASA’s Lucy mission flew by its first asteroid this week, its cameras captured a surprise. The Lucy spacecraft zoomed by the small asteroid Dinkinesh, located in our solar system’s main asteroid belt between the orbits of Mars and Jupiter. (Lockheed Martin is a NASA partner on the Lucy mission.) Preparing for future flybysThe data collected during the Lucy mission flyby will continue to return to Earth over the next week. There are about 7,000 Trojan asteroids, and the largest is 160 miles (257 kilometers) across.

CAPE CANAVERAL, Fla. (AP) — NASA’s Lucy spacecraft on Wednesday encountered the first of 10 asteroids on its long journey to Jupiter. The spacecraft will swing past eight Trojans believed to be up to 10 to 100 times bigger than Dinkinesh. The spacecraft is named after the 3.2 million-year-old skeletal remains of a human ancestor found in Ethiopia in the 1970s. Lucy will next swing past an asteroid named after one of the fossil Lucy's discoverers: Donald Johanson. Then in October, it launched a spacecraft to a rare, metal-rich asteroid named Psyche.

☆ NASA’s Lucy mission will closely fly by the asteroid Dinkinesh

CNN —The NASA Lucy mission is about to have its first encounter with a space rock. The spacecraft, launched in October 2021, will fly by the small asteroid Dinkinesh on Wednesday. Dinkinesh is about half a mile (1 kilometer) wide and is situated in the main asteroid belt between the orbits of Mars and Jupiter. Each of the asteroids Lucy will fly by differ in size and color. These are some of the asteroids that the Lucy mission will fly by over the next 12 years.
