NASA spacecraft snaps detailed asteroid picture from closest orbit yet It’s a record breaking distance for OSIRIS-REx

NASA ' s OSIRIS-REx mission has selected four potential sites where the spacecraft will grab a sample of the asteroid Bennu. Here 's 4 Places It May Land . When a NASA spacecraft makes its move to grab a piece of space rock in 2020, will it snatch at a sample of a dark, sandy Nightingale or of a very

NASA has created a map of 'potentially hazardous' asteroids that could pose an impact threat to Earth. This NASA graphic shows the orbits of all the known Potentially Hazardous Asteroids (PHAs) Shown here is a close-up of the orbits overlaid on the orbits of Earth and other inner planets .

NASA’s OSIRIS-REx spacecraft is currently hanging out around the asteroid known as Bennu. It’s been there for months, taking photos and scanning the asteroid’s surface to get a better idea of exactly what dangers the probe might face when it eventually touches down.

Now, after scrutinizing every square inch of the massive rock, NASA has narrowed down the possible landing sites to just four candidates. Each of the four spots is relatively inviting, with little in the way of large debris, but the science team still has some work to do before they can make the final call.

NASA spacecraft will return the asteroid samples to Earth on September 2023. The team leading NASA ' s first mission to take a rock sample from the asteroid Bennu has selected four Hydrated minerals are also present, which indicates that Sandpiper may contain unmodified water-rich material.

Here are a variety of space missions worth keeping tabs on over the next decade or so. It’ s also a source of intrigue for scientists searching for clues to where life may have once existed in the solar system. The mission will land a small probe on the surface, as well as three hopping mini-rovers That means, according to NASA , it will potentially spot thousands of exoplanets and more than a

When the mission first launched, NASA believed things were going to progress faster than they have. When the probe arrived at Bennu it discovered that the asteroid is actually far more “messy” than anyone could have guessed, with debris scattered all over the surface. This has complicated the search for a suitable touchdown site.

The ultimate goal has always been to retrieve samples of the asteroid’s material and return it to Earth. Selecting where to grab that sample from is difficult due to the requirements of the sample-collection system on the spacecraft. The material has to be smaller than an inch or the probe won’t be able to grab it, but the four potential landing sites seem to offer suitable material.

“We knew that Bennu would surprise us, so we came prepared for whatever we might find,” OSIRIS-REx principal investigator Dante Lauretta said in a statement. “As with any mission of exploration, dealing with the unknown requires flexibility, resources and ingenuity. The OSIRIS-REx team has demonstrated these essential traits for overcoming the unexpected throughout the Bennu encounter.”

From here, the team will narrow down the selections to just two and then perform flybys of the locations to eventually select the sample collection site. That maneuver won’t actually come until later next year, and the flight back to Earth will take another three years, so we won’t actually get any asteroid bits from Bennu until late 2023 at the earliest.

Asteroid 'the size of the Great Pyramid' to fly past Earth this month.
A huge chunk of space rock - which has been compared to the size of the Great Pyramid - will hurtle past our planet later this month. But (despite reports from tabloid news outlets), it’s not time to head to the doomsday bunkers quite yet. Yes, asteroid 2019 OU1 is fairly large (it’s thought to be 233ft to 524ft across), but it’s not a ‘planet killer’ or even a ‘city killer’. It’s also going to miss us by a fairly large margin on August 28, shooting past at around 639,000 miles away (equal to two and a half the distance of the moon).
