Live coverage: Two satellites lift off aboard Ariane 5

Turkey’s most advanced Earth observation satellite will ride a four-stage Vega rocket into polar orbit nearly 435 miles above Earth to begin collecting high-resolution images for Turkish military and security authorities.

Track the progress of the MASCOT lander, a tiny robot developed in Germany and France, as it explores asteroid Ryugu for a daring mission to hop across the austere world’s boulder-strewn landscape, taking pictures and collecting scientific data along the way. The robotic probe was released from the Hayabusa 2 spacecraft around 0200 GMT Wednesday (10 p.m. EDT Tuesday), and touched down a few minutes later.

A three-man crew led by six-time space flier Yuri Malenchenko rode a Soyuz rocket into orbit Tuesday, speeding away from a Kazakh launch pad on a six-hour chase of the International Space Station. Docking occurred at 1733 GMT (12:33 p.m. EST).
