Video: Rosetta scientist Matt Taylor on the end of mission

NASA’s InSight lander has placed a protective enclosure over a French-developed seismometer designed to detect tremors on Mars, completing the deployment of the first of two science instruments delivered to the Red Planet in November.

Three space station crew members made final preparations Friday for undocking and landing in Kazakhstan early Saturday to close out a 186-day stay in orbit.
