The Cygnus spacecraft has separated from the second stage of the Antares rocket.
We have main engine cutoff.
NASA commercial cargo provider Northrop Grumman is targeting today for the launch of its 15th resupply mission to the International Space Station. The five-minute launch window opens at 12:36 p.m. EDT. Live launch commentary has begun on NASA TV.
Loaded with about 8,000 pounds of research, crew supplies, and hardware, Northrop Grumman’s Cygnus cargo spacecraft will launch on the company’s Antares rocket from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.
A launch today would mean a scheduled arrival at the space station Monday, Feb. 22, of the Cygnus spacecraft, dubbed the SS Katherine Johnson.
The latest Wallops Range forecast keeps weather at 75% favorable for the 12:36 p.m. EST launch window today of NASA commercial cargo provider Northrop Grumman‘s Antares rocket and Cygnus cargo spacecraft from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility near Chincoteague, Virginia. The International Space Station-bound Cygnus is loaded with about 8,000 pounds of cargo.
The countdown is underway for today’s 12:36 p.m. EST launch window of NASA commercial cargo provider Northrop Grumman‘s Antares rocket and Cygnus cargo spacecraft. Weather continues to be 75% favorable for the launch of this resupply mission to the International Space Station.
For those who’d like to follow along with the count early, live video and control room chatter is now airing on NASA Wallops’ IBM Cloud Video. Live coverage of the launch with commentary will air on NASA Television, the agency’s website and the NASA app beginning at 12 p.m. EST.
The five-minute launch window opens at 12:36 p.m. EST, with liftoff taking place at Virginia Space’s Mid-Atlantic Regional Spaceport Pad-0A at NASA’s Wallops Flight Facility near Chincoteague, Virginia.

The NASA Visitor Center — including its parking lot — at Wallops will be CLOSED for this launch.
Viewing locations on Chincoteague Island include Robert Reed Park on Main Street or Beach Road spanning the area between Chincoteague and Assateague Islands. The beach at the Assateague Island National Seashore/Chincoteague National Wildlife Refuge will NOT be open during the launch.
This launch occurs during daylight hours, so it will not be as visible as a launch at night. However, depending on cloud cover and other local conditions (such as elevation and obstruction of the horizon), it still may be visible in the Mid-Atlantic region.
Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations.
This Cygnus is loaded with about 8,000 pounds of research, crew supplies, and hardware. Research investigations launching to the orbiting laboratory aboard this Cygnus include:
- The Spaceborne Computer-2 from Hewlett Packard Enterprise, which aims to demonstrate that current Earth-based data processing of space station experimental data can be performed in orbit
- An experiment studying muscle strength in worms
- An investigation into how microgravity may optimize the production of artificial retinas
Cargo resupply from U.S. companies ensures a national capability to deliver critical science research to the space station, significantly increasing NASA’s ability to conduct new investigations at the only laboratory in space.
The Friday Wallops Range forecast keeps weather at 75% favorable for tomorrow’s launch window of NASA commercial cargo provider Northrop Grumman‘s Antares rocket and Cygnus cargo spacecraft.
The primary concerns for launch at this time are ground winds and a slight chance of cloud ceilings and cumulus clouds.
Rain showers will continue throughout the day on Friday as an area of low pressure moves off the Mid-Atlantic Coast. As the associated frontal boundary moves out to sea, precipitation will come to an end late this afternoon into the early evening hours.
High pressure will quickly build into the region overnight, providing a decrease in cloudiness and chilly conditions for launch. Breezy, northwesterly winds (20-25 knot gusts) are expected overnight tonight and into the day on Saturday. Gusty winds will result in sea states generally running from 4-6 feet in the surveillance areas off the Wallops coast.
Although clouds will decrease in coverage late tonight and into the morning on Saturday, some scattered cloudiness is expected at T-0.
Northrop Grumman is targeting 12:36 p.m. EST Saturday, Feb. 20, for the International Space Station-bound Cygnus, loaded with about 8,000 pounds of research, crew supplies, and hardware. Launch will be from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility near Chincoteague, Virginia.
