Watch as the simulation reveals the merger's brighter, more variable X-rays. https://go.nasa.gov/2OsaMAs Credit: NASA's Goddard Space Flight Center Music: "Games Show Sphere 01" from Killer Tracks This video is public domain and along with other supporting visualizations can be downloaded from the Scientific Visualization Studio at: http://svs.gsfc.nasa.gov/13043 ... https://www.youtube.com/watch?v=uDhDZi9Qxhk

A journey of a billion miles and back begins with a launch. OSIRIS-REx's goal: Travel to asteroid Bennu, collect a sample, and return it home. But why Bennu? Meet the NASA Explorers looking for clues to our early solar system in a sample of asteroid rock. It’s not rockets and satellites that make NASA soar. It’s people. Go inside the space agency and follow the pioneers, risk-takers and experts at the frontline of exploration. This season, follow along with the OSIRIS-REx team, as they launch a spacecraft to an asteroid, collect a sample of Bennu, and bring it home to Earth.

Cameras outside the International Space Station captured views August 31 of Hurricane Dorian at 11:28 a.m. Eastern time as it churned over the Atlantic Ocean. The storm, which is moving in a generally westerly direction with winds of 145 miles an hour, may approach Category 5 hurricane status, according to the National Hurricane Center, as it makes its way toward the east coast of Florida and a possible ride up the southeastern seaboard next week.
