ISS astronauts welcome supply space craft

ABOARD ISS (NBC) A spacecraft carrying more than 7,600 pounds of supplies and science experiments arrived at the International Space Station Saturday morning.

The Cygnus cargo ship was secured just after 6:00 a.m. Eastern time by French astronaut Thomas Pesquet using the stations' 58-foot robotic arm.

Astronaut Peggy Whitson joined Pesquet at the controls as the spacecraft orbited earth about 250 miles above Germany.

Experiments flying on Cygnus include a chamber that will grow plants in space, an investigation that could improve chemotherapy for cancer treatment and new tools to produce earth-like cell cultures.
