About 46 years after NASA’s Voyager 1 and Voyager 2 launched on an epic journey to explore space, the probes’ antique hardware continues to receive tweaks from afar. One update, a software fix, ought to tend to the corrupted data that Voyager 1 began transmitting last year, and another set aims to prevent gunk from building up in both spacecraft’s thrusters. Together, these updates intend to keep the spacecraft in contact with Earth for as long as possible.

NASA’s Lucy spacecraft is preparing for its first close-up look at an asteroid. On Nov. 1, it will fly by asteroid Dinkinesh and test its instruments in preparation for visits in the next decade to multiple Trojan asteroids that circle the Sun in the same orbit as Jupiter. Dinkinesh, less than half a mile, or 1 kilometer, wide, circles the Sun in the main belt of asteroids located between the orbits of Mars and Jupiter. Lucy has been visually tracking Dinkinesh since Sept. 3; it will be the first of 10 asteroids Lucy will visit on its 12-year voyage. To observe so many, Lucy will not stop or orbit the asteroids, instead it will collect data as it speeds past them in what is called a “flyby.”
—UC San Diego: “How Could a Piece of the Moon Become a Near-Earth Asteroid? Researchers Have an Answer“
A team of astronomers has found a new clue that a recently discovered near-Earth asteroid, Kamooalewa, might be a chunk of the moon. They hypothesized that the asteroid was ejected from the lunar surface during a meteorite strike–and they found that a rare pathway could have allowed Kamooalewa to get into orbit around the sun while remaining close to the orbits of the Earth and the Moon. The research team details their findings in the Oct. 23 issue of the journal Nature Communications Earth & Environment. Kamo`oalewa has been the object of several astronomy studies in recent years. As a result, a Chinese mission launching in 2025 is set to land on the asteroid and return samples to Earth.
