Astronaut medical issue forces NASA to call off spacewalk at space station

NASA has called off plans for a spacewalk outside the International Space Station this week due a medical issue with one of the astronauts due to join the excursion, agency officials said Monday (Aug. 23). A "minor medical issue" involving NASA astronaut Mark Vande Hei is the reason for the spacewalk's postponement, the U.S. space agency wrote in an update.
