Atlas V Rocket Poised for Space Station Cargo Run Today

What's Inside the 7600 Pounds of Supplies the Cygnus Spacecraft is Carrying to the ISS

Orbital ATK's seventh cargo delivery flight to the station launched at 11:11 a.m. EDT Tuesday on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. (3,463 kilograms) of food, supplies and science experiments to the station.

Aerospace giant Orbital ATK will torch one of its spacecraft as part of an experiment to see how fire acts in microgravity. It was the 71st Atlas V launch.

Space Cost Daily will carry the launch live on Space Coast Daily TV starting at 10 a.m.

The Cygnus is pressed with more than 7,600 lbs.

The launch window opens at 11:11 a.m and weather remains favorable. It will launch atop Orbital ATK's Antares 230 rocket.

Normally it takes two to three days for cargo vehicles to meet up with the ISS, but the Cygnus is actually going to hang out in orbit for a little while once it launches.

The Antares actually returned to flight in October of a year ago, performing a picture-perfect cargo resupply launch to the ISS.

The next Cygnus flight, OA-8E, is planned for October 2017.

It's launch day for a United Launch Alliance mission named after John Glenn, an astronaut and former USA senator who once rode into space on a predecessor of the rocket that launches today.

"We are sorry we missed Easter", said Culbertson, a former NASA astronaut, "but we're pretty sure they'll be excited about their Easter baskets and whatever great things International Space Station science put on board for them". That's because a pair of astronauts are scheduled to launch early Thursday morning on a Russian Soyuz rocket.

There are also experiments to improve chemotherapy and 38 mini-satellites called CubeSats that will also be used for research.

Expedition 51 astronauts Thomas Pesquet of ESA (European Space Agency) and Peggy Whitson of NASA will use the space station's robotic arm to grapple Cygnus, about 6:05 a.m. Saturday.

But first, the capsule just has to get to the station.

The spacecraft will remain at the orbiting laboratory until July, when it will be loaded with unneeded equipment and detached for eventual burn up in Earth's atmosphere.

Tuesday's launch marked the first time NASA, in coordination with the ULA and Orbital ATK, has broadcast a rocket launch with a 360-degree view, which should "virtually place the public at the base of the rocket during launch".
