"A new shipment of science, spacewalk gear and crew supplies is on its way to the International Space Station," NASA says. Astronauts on the International Space Station will grapple an arriving Cygnus supply spacecraft this morning, with coverage starting at 5:30 a.m. EDT (0930 GMT).

From NASA:
Cygnus will carry almost 7,500 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory to support dozens of science and research investigations that will occur during Expeditions 47 and 48.
The spacecraft will arrive at the station on Saturday, March 26, at which time Expedition 47 Commander Tim Kopra of NASA and Flight Engineer Tim Peake of ESA (European Space Agency) will grapple Cygnus, using the space station's robotic arm, at approximately 6:40 a.m. NASA TV coverage of rendezvous and grapple will begin at 5:30 a.m.
After Cygnus capture, ground commands will be sent from mission control in Houston to the station's arm to rotate and install the spacecraft on the bottom of the station's Unity module. Coverage of installation will begin at 9:15 a.m.
