Hellllooooo planet Earth! NASA astronaut Jack Fischer excitedly waves to the camera during Tuesday’s spacewalk on the International Space Station (iss). From 250 miles above our home planet, Fischer and astronaut Peggy Whitson performed a contingency spacewalk to replace a failed data relay box. During their 2 hour 46 minute spacewalk, they were also able to install a pair of antennas on station to enhance wireless communication for future spacewalks.
