Astronauts conduct spacewalk outside space station

CAPE CANAVERAL, Fla. (AP) — Two space station astronauts are taking a spacewalk.

Russians Alexander Skvortsov and Oleg Artemiev ventured out Monday. They have set loose a tiny Peruvian research satellite and also are installing fresh science experiments and retrieving old ones.

The nanosatellite is just 4 inches square and barely 2 pounds. It holds cameras that will aim at Earth. It's a technological learning experience for the National University of Engineering in Lima.

The satellite is named Chasqui (CHOS-key) after the Inca messengers who were fleet of foot.

Meanwhile, American spacewalks remain on hold. NASA hoped to resume spacewalks this month after a yearlong investigation but delayed the activity until fall to get fresh spacesuit batteries on board. The SpaceX company will deliver the batteries on a Dragon supply ship next month.
