Beautiful photo of our #Stargazer L-1011 and the #Pegasus rocket taken by @NASA_EDGE. Our ferry flight has been moved one day to accommodate additional testing, launch date should remain June 14 from Kwajalein Atoll. @NASA_LSP #NASAICON

[Orbital ATK @OrbitalATK]

The #Pegasus team is busy conducting final tests aboard the #Stargazer L-1011 in preparation for tomorrow's ferry flight to Kwajalein Atoll for the June 14th launch of the Orbital ATK-built ICON satellite for @NASA! Be sure to follow @NASA_LSP for live launch coverage. #NASAICON

Great timelapse of our #OA9 #Cygnus arriving at the @Space_Station last week! https://t.co/WAuLFHFP1C

[Ricky Arnold @astro_ricky]

#tbt! The @OrbitalATK #Cygnus brings the goods to @Space_Station and @Astro_Maker uses #Canadarm to go out and grab them.

[Orbital ATK @OrbitalATK]

#tbt to the start of our #OA9 mission! Our #Antares rocket lifted off from @NASA_Wallops on May 21, sending the S.S. J.R. Thompson #Cygnus to orbit. Cygnus arrived at the @Space_Station on May 24.

[Defense Daily @DefenseDaily]

Omega, @OrbitalATK’s new heavy-class rocket, will have a payload capacity of up to 10,100 kg to Geosynchronous Transfer Orbit (GTO) and up to 7,800 kg to Geostationary Equatorial Orbit (GEO) https://t.co/ecB7VBKzK4

Fun fact: our longest operating satellite, Landsat-5, holds the Guinness World Record for 'Longest-operating Earth observation satellite' after 29 years in operation! Launched in 1984, the satellite was decommissioned in 2013. @GWR

[Orbital ATK @OrbitalATK]

#DYK that, when it comes to satellites, we have more than 1,500 years of cumulative in-orbit operational experience? Today, 89 of the 186 satellites we have built over the past 35 years are still in operation.

Mission complete! Yesterday our teams concluded in-orbit testing of @yahsatofficial’s Orbital ATK-built Al Yah 3 satellite and successfully handed over controls to Yahsat. More about the satellite: https://t.co/joiJKJ0Tgu https://t.co/1fymO0r0hV
