Latest Weather Forecast for April 17 Antares Launch: 90% Favorable

The latest weather forecast stands at 90% favorable for the April 17 launch of Northrop Grumman’s Antares rocket from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility. At this time, cloud ceilings, ground winds and thick clouds are the weather concerns for a launch attempt on Wednesday afternoon.

NASA’s commercial partner Northrop Grumman is scheduled to launch its Antares rocket carrying its Cygnus cargo spacecraft to the International Space Station at 4:46 p.m. EDT Wednesday, April 17.

Loaded with 7,500 pounds of research, crew supplies and hardware, this is Northrop Grumman’s 11th commercial resupply NASA-contracted mission. It will launch from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility.

High pressure builds into the region overnight through tomorrow, allowing winds to subside later this evening. Tranquil and seasonable conditions prevail tomorrow with the high located just to our south. Another area of high pressure dips south into the northeast states Tuesday night into Wednesday, forcing a cold front south over the Delmarva Wednesday morning, then eventually the Wallops area.

Media accreditation is open for the launch of Northrop Grumman’s next delivery of NASA science investigations, supplies and equipment to the International Space Station on April 17.

Northrop Grumman’s Cygnus spacecraft is targeted to launch on the company’s Antares rocket at 4:46 p.m. EDT from Pad-0A of the Mid-Atlantic Regional Spaceport (MARS) at NASA’s Wallops Flight Facility on Wallops Island in Virginia.

On this mission, Northrop Grumman will use a new late load capability. Previously, all cargo had to be loaded about four days prior to launch. This new capability will allow time-sensitive science experiments to be loaded into Cygnus just 24 hours before liftoff.

CRS-10 Launch Blog Coverage Concludes

Northrop Grumman’s Cygnus spacecraft is on its way to the International Space Station with about 7,400 pounds of cargo after launching at 4:01 a.m. EST Saturday from NASA’s Wallops Flight Facility on Virginia’s Eastern Shore.
