But the mission encountered problems and burned ... essentially collections of rocks held together loosely by gravity, such as the asteroid Bennu that was visited by NASA’s ORISIS-REx spacecraft.

Research on asteroid Bennu reveals no evidence of a potential fifth force that could explain dark matter. NASA’s OSIRIS-REx mission tracked Bennu’s orbit with exceptional accuracy, allowing ...

Most of the $1 billion mission's cache was set aside for future analysis. Scientists stress more testing is needed to better understand the Bennu samples as well as more asteroid and comet sample ...

The asteroid Bennu has been at the centre of scientific discussions recently, especially after researchers analysed surface samples collected by NASA’s OSIRIS-REx mission. While much of the ...

Many biological molecules are chiral, meaning they exist in two forms that are mirror images of each other, like left and ...

If the asteroid’s path ends at Earth, NASA isn’t helpless, Fieber-Beyer said. For the first time in known history, NASA's ...
