NASA’s Lucy spacecraft is speeding towards yet another near encounter with an asteroid

NASA Lucy Spaceship This weekend, we will be heading past a small asteroid as we will continue our path to even bigger prizes: Unexplored: A flock of asteroids near Jupiter.

That’s probably The second asteroid encounter It was released for Lucy in 2021 as Quest to turn 11 Space Lock. A close approach should help scientists better understand the early solar system when planets are forming. The asteroid is Ancient leftovers.

The upcoming flyby is a 2027 dress rehearsal in which Lucy reached the first so-called Trojan asteroid near Jupiter.

Sunday’s spacecraft, making three scientific instruments, observes a harmless asteroid known as Donald Johansson. The encounter takes place 139 million miles (223 million kilometers) from Earth, the main asteroid belt between Mars and Jupiter.

A paleontologist named Lockheed Martin, the asteroid, the architect and operator of the spacecraft, is in mission control for all actions. He discovered Ethiopian fossil Lucy 50 years ago. The spaceship is named after a famous human ancestor.

NASA’s Lucy approaches 596 miles (960 kilometers) to this asteroid, an estimated 2½ miles (4 kilometers), but much shorter in width. Scientists should consider their size and shape better after a short visit. The spacecraft zooms at over 30,000 mph (48,000 kph).

The asteroid is one of countless fragments believed to have arisen from a massive collision 150 million years ago.

“It’s not going to be a basic potato. We already know that,” said Hal Levison, chief scientist at the South West Research Institute.

Rather, Levison said the asteroid could resemble bowling pins and snowmen like Arocos, the Kuiper Belt object that NASA’s New Horizon spacecraft visits in 2019. Another possibility is that two elongated but separate asteroids are far apart.

“We don’t know what to expect, and that’s what makes this so cool,” he said.

There is no communication with Lucy during the flyby as the spacecraft is keeping its antenna away from Earth to track the asteroid. Levison expects to have most of the scientific data within a day.

Lucy’s next stop, “Main Event,” is a Trojan asteroid that, as Levison calls it, shares Jupiter’s orbit around the Sun. A herd of Trojans preceded the largest planet in the solar system, circles the sun. Lucy visited eight people from 2027 to 2033, some of which will be paired with two.

Lucy’s first asteroid flyby came in 2023 as she passed Little Dinkinesh, located in the main asteroid belt. The spaceship discovered a mini-moon around it.

Scientists are puzzled by mysterious object speeding through galaxy at over a million miles per hour

An object moving through space at close to 1 million miles per hour has been detected, moving so fast that it is leaving the Milky Way galaxy. Scientists are now trying to identify this mysterious object.

Currently located 400 light-years away, the object known as CWISE J1249 is unlikely to be a spacecraft due to its massive size. It is approximately 30,000 times the mass of Earth, making it about 8% of the mass of the Sun.

This unusual size places J1249 somewhere between a star and a planet, as described by Dr. Darren Baskill, a lecturer in astronomy at the University of Sussex. According to Dr. Baskill, stars moving at such high speeds are rare.

The object’s speed is so rapid that it could exit the Milky Way galaxy in just a few tens of millions of years, which is a short period considering stars’ long lifespans.


This massive object, flying at 0.001% of the speed of light, has the potential to escape the galaxy and venture into intergalactic space.

Discovered by citizen scientists contributing to NASA’s Backyard Worlds: Planet 9 project, J1249’s speed is approximately 2.6 times faster than any space probe ever launched.

A new study, pending peer review, confirms these findings and further characterizes the object discovered through the initiative.

The object, with an unusual composition compared to stars and brown dwarfs, may be the first star of its kind in the galaxy, based on NASA’s observations.

Researchers believe the high-speed movement of the object may be linked to a supernova explosion in a binary star system or encounters with black holes in a star cluster.

Dr. Baskill suggests that gravitational slingshots could explain the extreme speed of J1249, potentially originating from the galaxy’s dense center and accelerated through gravitational interactions.
