You may have heard that the historic all-female space walk that was originally scheduled for yesterday was scrapped by NASA earlier this week. Let's take a look at what happened. | National Geographic TV

On yesterday's spacewalk, astronauts Chris Cassidy and Robert Behnken each made their 10th spacewalk, tying the record for most by NASA Astronauts. Cassidy is now ninth among Americans for most hours spacewalking, and Behnken is fourth. Congratulations! https://go.nasa.gov/39isE8Q | NASA - National Aeronautics and Space Administration
