OSIRIS-APEX spacecraft takes selfie with Earth during flyby
NASA's Osiris-Apex spacecraft has captured a selfie with Earth as it used the planet's gravity to push onward towards asteroid Apophis. On 23 September, the probe skimmed just 3,438 kilometres above the surface, flying closer than many high-orbit satellites. During the manoeuvre, it passed within roughly 2,100 miles of Earth, about half the height of a typical low Earth orbit.
