Vesta, a massive world in the solar system's asteroid belt , sports two huge trough features that have long puzzled scientists, and it doesn't look like the mystery will be solved anytime soon, at least not in a new study of the features.
NASA visited Vesta in 2011 and 2012 with the Dawn spacecraft, which mapped the large asteroid's surface in unprecedented detail.
EarthSky | 1,001st near-Earth asteroid glimpsed with radar
The video above shows asteroid 2016 AJ193 rotating as it swept past Earth. NASA’s Goldstone's 70-meter (230-foot) antenna acquired the images on August 22, 2021.
Meanwhile, from August 20 to 24, scientists studied the rock with the Goldstone antenna near Barstow, California. They sent radio signals to the asteroid and analyzed the radar reflections or “echoes” that returned.

(Washington, DC) — NASA is keeping an eye on a massive asteroid barreling toward the Earth’s orbit. It’s about three times larger than the Statue of Liberty with a diameter between 300 and 900 feet. An asteroid that size could cause significant damage if it hit the planet.
Planetary Radar Observes 1,000th Near-Earth Asteroid Since 1968
This animation shows asteroid 2016 AJ193 rotate as it was observed by Goldstone's 70-meter (230 foot) antenna on Aug. 22, 2021. Three-quarters of a mile (1.3-kilometers) wide, the object was the 1,001st near-Earth asteroid to be measured by planetary radar since 1968.
Seven days after this historic milestone, a massive antenna at NASA's Deep Space Network Goldstone complex imaged another, far larger object.
Geologists propose theory about a famous asteroid
"When we think of asteroid belts, we probably picture Han Solo maneuvering the millennium falcon through a dense set of irregularly shaped gray rocks in space," Christian Klimczak, associate professor in the Franklin College of Arts and Sciences department of geology.
Dawn was the space probe launched by NASA in September 2007 with the mission of studying two of the three known protoplanets of the asteroid belt, Vesta and Ceres.
Odds of asteroid Bennu hitting Earth put into perspective
The space agency , which has been tracking the building-sized rock since it was discovered in 1999, revised its prediction based on new tracking data.
Even with the small shift in odds, it seems likely we won't face the kind of scenario featured that in the 1998 science-fiction disaster film "Armageddon" when Stamper, played by Bruce Willis, and his team had to try to blow up a huge asteroid that was on an extinction-making collision course

In 2016, scientists on Expedition 364 traveled to the Chicxulub impact crater, located northeast of the Yutucán peninsula in Mexico, to extract a cylinder of rock from the site. They did not drill into the middle of the crater, but rather from its outside border, known as the peak ring.
"It is one of the advantages of impact craters. Their formation follows very well-defined laws of physics," explains Jen Olof Ormö, an investigator from the Astrobiology Center at Spain's national research institute CSIC and a coauthor of the study.
Geologists propose theory about a famous asteroid: The troughs on Vesta have long been a topic of
The asteroid Vesta is the second largest asteroid in our solar system. With a diameter of about 330 miles, it orbits the sun between the planets Mars and Jupiter.
Asteroids have long played a part in building popular fascination with space. "Marooned off Vesta" was the first story published by American writer Isaac Asimov, the third story he wrote, appearing in the March 1939 issue of the science fiction magazine Amazing Stories.
Does Commercial Asteroid Mining Still Have A Future?
What happened to the space-mining industry? A decade ago, the mainstream media was full of articles about how mining asteroids for precious metals, metal composites and even rare earth metals would revolutionize the commercial space economy.
There were grandiose plans to reap untold fortunes from near-Earth asteroids (NEAs), either robotically or even by sending private commercial astronauts to act as space miners.
Asteroid thrice the size of Statue of Liberty to fly past Earth soon, but here's the good
A giant asteroid called 2021 NY1, which is up to three times the size of the Statue of Liberty, would enter the Earth's orbit in the coming days.
According to NASA, 2021 NY1 would enter the orbit of Earth in September. NASA is tracking this giant rock which has a diameter of 130-300m. It is to be noted that the height of Statue of Liberty is only 93 meters. This asteroid is moving towards earth at a speed of 33659 kmph.
