Live coverage: ExoMars mission underway after Proton launch

NASA is examining options to launch a robotic mission as soon as 2026 to pick up rock specimens from the surface of Mars and bring them back to Earth, moving forward the timeline for a sample return mission as the agency postpones plans for a new Mars reconnaissance and data relay orbiter.

NASA is taking steps to rein in costs, emphasizing bonds with private sector companies, and signaling it might be open to a future where the agency’s flagship Orion deep space capsule and Space Launch System are no longer necessary to explore deep space, at least in their current forms.

A Russian cosmonaut and his two NASA crewmates undocked from the International Space Station and landed in Kazakhstan early Friday, returning to an unfamiliar world in the grip of a pandemic that will force them to extend the social isolation they were hoping to end.
