Boeing’s Starliner capsule, carrying an instrumented astronaut test dummy nicknamed “Rosie,” is on track for launch Friday on an unpiloted test flight to the International Space Station, mission managers said Tuesday. The flight is a major milestone in NASA’s push to resume launching U.S. crews from American soil.

U.S. military officials and United Launch Alliance have dedicated the planned launch Saturday of an Atlas 5 rocket with the military’s winged mini-space shuttle to coronavirus first responders, front-line workers and all who have been affected by the pandemic.

A fresh image from NASA’s New Horizons spacecraft released Tuesday showed the mission’s distant flyby target a billion miles beyond Pluto — nicknamed Ultima Thule — has an elongated shape like that of a peanut shell or a bowling pin, and the prospect of higher-resolution pictures arriving on Earth later in the day had scientists salivating for more.
