KENNEDY SPACE CENTER, FL – The ‘SS John Glenn’ cargo freighter stands proudly poised for launch at pad 41 from the Florida Space Coast on Tuesday April 18, loaded with a stash of nearly 4 tons of science investigations and essential supplies atop a United Launch Alliance Atlas V rocket destined for the multinational crew aboard the International Space Station (ISS).

The lunchtime liftoff of the ‘SS John Glenn’ Cygnus resupply spacecraft manufactured by NASA commercial cargo provider Orbital ATK is slated for 11:11 a.m. EDT Tuesday, April 18 from Space Launch Complex 41 on Cape Canaveral Air Force Station, FL.

The US cargo ships provided by NASA suppliers Orbital ATK and SpaceX every few months act as NASA’s essential railroad to space. And they are vital to operating the station with a steady stream of new research experiments as well as essential hardware, spare parts, crew supplies, computer, maintenance and spacewalking equipment as well food, water, clothing, provisions and much more.

The launch window lasts 30 minutes and runs from 11:11-11:41 a.m. EDT April 18.

Excited spectators are gathering from near and far and Tuesday’s weather outlook is spectacular so far.

Blastoff of the S.S. John Glenn on the OA-7 or CRS-7 flight counts as Orbital ATK’s seventh contracted commercial resupply services mission to the ISS for NASA.

The ‘S.S. John Glenn’ is named in honor of legendary NASA astronaut John Glenn – the first American to orbit Earth back in February 1962.

If you can’t attend in person, there are a few options to watch online.

NASA’s Atlas V/Cygnus CRS-7 launch coverage will be broadcast on NASA TV and the NASA launch blog beginning at 10 AM, Tuesday morning.

You can watch the launch live NASA TV at: http://www.nasa.gov/nasatv

And for the first time ever you can also watch the launch live via a live 360 stream on the NASA Television YouTube channel. The 360 degree broadcast starts about 10 minutes prior to lift off at:

The late morning daytime launch offers the perfect opportunity to debut this technology with the rocket magnificently visible atop a climbing plume of smoke and ash – and with a “pads-eye” view!

From a weather standpoint, Tuesday’s launch outlook is outstanding at this time.

According to meteorologists with the U.S. Air Force 45th Weather Squadron we are forecasting a 90 percent chance of “go” conditions at the 11:11 a.m. EDT launch time. The primary concern is for the possibility of cumulus clouds.

The forecast calls for temperatures of 75-76° F with on-shore winds peaking below 10 knots during the countdown.

In the event of a delay for any reason related to weather or technical issues a backup launch opportunity exists for Wednesday, April 19, and also looks promising.

The AF is also predicting the same 90 percent chance of “go” conditions at launch time. With the primary concern again being for the possibility of cumulus clouds.

The rocket was rolled out to pad 41 at about 9 a.m. EDT this morning Monday April 17, in a process that takes about 25 minutes

The rocket and spacecraft passed the Launch Readiness Review held by United Launch Alliance and Orbital ATK on April 15. Launch managers from ULA, Orbital ATK and NASA determined all is ready for Tuesday’s targeted launch to the ISS.

OA-7 is loaded with 3500 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.
