“Missions typically return only tiny amounts of material to Earth. “At present we don't fully understand what asteroids are made of,” co-author Mikael Granvik, of Luleå University of Technology, Sweden, and the University of Helsinki, Finland, says in a statement. It would be faster, cheaper and more efficient than our big budget missions, including the current OSIRIS-REx sample and return mission to the asteroid Bennu and Japan’s Hyabusa 2 mission to the asteroid Ryugu, which take millions of dollars and years of planning and zipping through space to accomplish.
Any space rocks that get caught in Earth’s orbit are typically too small and moving too quickly for our current asteroid surveys to detect.īut if we could detect these bits of space debris when they enter our orbit, we could capture samples from the space rocks and bring them down to Earth to study, new research in the journal Frontiers in Astronomy and Space Science suggests. Examining those little space rocks, they believe, could be a big boost to astronomy.Īstronomers involved in the Catalina Sky Survey first discovered that Earth had a tiny second moon-a space rock less than 10 feet in diameter-in 2006, but only by serendipitous chance. Now, reports Amber Jorgenson at Discover, astronomers have called for a new project using the Large Synoptic Survey Telescope (LSST)-a device still under construction in Chile-to look for the mini-moons. Researchers believe that our planet is potentially orbited by lots of “mini-moons,” little asteroids gripped by Earth’s gravity that swing around the planet for a little while before burning up in our atmosphere or being flung back into the cosmos.

What do you think of the NASA project to study the Bennu asteroid? We want to hear from you.Scientists want to know how that warmth changes the orbit of asteroids and other space objects. The Yarkovsky effect is what happens when a cold piece of rock gets close enough to the sun to get heated. That path is changing because of something called the Yarkovsky effect. Another thing that makes Bennu dangerous is its path around the solar system.The asteroid ".has a relatively high probability of impacting the Earth." in less than 200 years, according to a NASA statement.
Scientists want to learn as much as possible about Bennu because of the danger it could cause our planet.The space agency says some of those particles may "contain the.precursors to the origin of life and the Earth's oceans." Rock particles cover the asteroid's surface. NASA researchers are calling Bennu a "primitive" asteroid - meaning it has been in existence for a long time.It is expected to land in the Utah desert in September of 2023. All of that material will return to earth inside a device the researchers are calling the Sample Return Capsule, or SRC.At that time, a part of the spacecraft shaped like a container will gather about 60 grams from Bennu's surface. The spacecraft will not land on Bennu, but will make contact with the asteroid briefly - for about five seconds.The plan is to put it in orbit around Bennu in about two years. That means the space agency can launch OSIRIS-Rex on that date or later. NASA officials say the launch window for the spacecraft opens Thursday, September 8. The American space agency, NASA, will start its investigation next month.Researchers want to take a close look at Bennu because it is considered one of the most dangerous asteroids in our solar system.It comes as close as 500,000 kilometers to the planet every six years.
