Live coverage: Space station crew concludes 186 days in orbit

Seven Japanese and Vietnamese smallsats are set to ride Japan’s solid-fueled Epsilon launcher into orbit at 0050 GMT Friday (7:50 p.m. EST Thursday) on a mission that engineers say will demonstrate the light-class rocket’s ability to accommodate multiple payloads on a single flight.

Boeing and SpaceX hope to launch commercial crew ferry ships on long-awaited test flights later this year, but both companies face major challenges getting the spacecraft certified before late 2019 when seats aboard Russian Soyuz spacecraft will no longer be easily available for NASA space station crews, officials told lawmakers Wednesday.

For the final time, a SpaceX Dragon cargo capsule approached the International Space Station Monday for capture with the research lab’s robotic arm, delivering more than 4,300 pounds of food, experiments and spare parts. Future Dragon resupply missions will use a new spaceship design to automatically dock with the space station.
