NASA scientists are tracking the upcoming Halloween flyby of asteroid 2015 TB145 with several optical observatories and the radar capabilities of the agency’s Deep Space Network at Goldstone, California. Only discovered sixteen days ago, the 400-metre-wide asteroid will fly past Earth at a safe distance slightly farther than the Moon’s orbit on 31 October at 5:05pm GMT.

UAE’s Hope spacecraft successfully reaches Mars, setting the stage for China and NASA to follow suit.

Ten days after a swingby to receive a gravitational boost toward its asteroid target, NASA’s OSIRIS-REx spacecraft turned one of its cameras back toward Earth, resolving its bluish home planet hanging in the void of space accompanied by the Moon.
