Mission Update

Northrop Grumman's NG-10 mission is scheduled to launch aboard the company's Antares rocket from NASA's Wallops Flight Facility no earlier than November 17. The 5-minute launch window will open at 4:01 a.m. EST/9:01 a.m. UTC. The company's Cygnus spacecraft will deliver science experiments and essential supplies to the crew on board the International Space Station.

NG-10 Launch Viewing Maps

Weather permitting, the launch of Northrop Grumman's Antares rocket from Wallops Island, Virginia on November 15, 2018 will be widely visible along the East Coast. See below for viewing maps.

Time of First Sighting

This map shows the rough time at which you can first expect to see Antares after it is launched. It represents the time at which the rocket will reach 5 degrees above the horizon and varies depending on your location. We have selected 5 degrees as it is unlikely that you'll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features. However, depending on your local conditions the actual time you see the rocket may be earlier or later. As an example, using this map when observing from Washington, DC shows that Antares will reach 5 degrees above the horizon approximately 110 seconds after launch (L + 110 sec).

Maximum Elevation Map

This map shows the maximum elevation (degrees above the horizon) that Antares will reach during its first stage burn. The maximum elevation depends on your location; the further away you are from the launch site, the closer to the horizon the rocket will be. As a reference, when you look at your fist with your arm fully outstretched, it spans approximately 10 degrees. Thus if you are in Washington, DC the highest point Antares will reach is approximately 11 degrees above the horizon, or just slightly more than a fist's width. The contours shown stop below 5 degrees. It is unlikely that you'll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features.

Second Stage Elevation Map

During second stage ignition, the rocket will still be fairly high up over the horizon as viewed from most locations. In addition, the solid motor on the second stage is usually brighter than the liquid fuel engines of the first stage. Even if you don't see the first stage, it is possible you may be able to spot the second stage! You should also remember that there is a 53 second gap between the first and second stages; during this time the rocket will not be visible. To facilitate you spotting the second stage, we have created a third map that shows the vehicles elevation (angle) over the horizon when the second stage lights up.

About Antares

Designed to provide responsive and low-cost access to space, Antares is a two-stage vehicle (with optional third stage) that provides low-Earth orbit (LEO) launch capability for payloads weighing up to 8,000 kg. Internally funded by Northrop Grumman, Antares completed a risk reduction mission and a demonstration of commercial re-supply services for the International Space Station (ISS) under a NASA Commercial Orbital Transportation Services (COTS) agreement in 2013. Northrop Grumman commenced delivery of cargo to the ISS under the NASA Commercial Resupply Services (CRS) contract in 2014.

About Cygnus

Cargo is delivered to the station using Northrop Grumman's Cygnus spacecraft. The Cygnus spacecraft consists of two modules: the Service Module (SM) which incorporates the avionics, propulsion and power systems from Northrop Grumman's flight proven LEOStar and GEOStar spacecraft buses; and the Pressurized Cargo Module (PCM) which carries the crew supplies, spares and scientific experiments. The SM is integrated and tested at Northrop Grumman's Dulles, Virginia satellite manufacturing facility. The PCM is supplied by Thales Alenia Space and is produced in Turin Italy.
