Live coverage: Space station crew safely returns to Earth

Astronomy Now speaks with Matt Taylor, Rosetta project scientist, at the European Space Agency’s mission control in Darmstadt, Germany, about the plan to crash land the spacecraft on comet 67P/Churyumov–Gerasimenko.

Astronaut Scott Kelly and cosmonaut Mikhail Kornienko are making final preparations for return to Earth Tuesday evening, closing out a record 340-day stay aboard the International Space Station where they served as medical test subjects to learn more about the long-term effects of weightlessness, space radiation and isolation.

Boeing’s work on the International Space Station, the CST-100 Starliner commercial crew capsule and NASA’s heavy-lift Space Launch System are under the umbrella of John Elbon, who leads the company’s space exploration division in Houston.
