Last November, Orbital ATK's stockholders approved the acquisition of their company by Northrop Grumman. The transaction is expected to be completed in the first half of 2018, after regulatory approvals.
Meanwhile, according to Spaceflight Now, the launch of the Pegasus XL rocket carrying the ICON satellite has been postponed to a date yet to be defined, in early 2018:
Launch time: TBD
Launch site: L-1011, Kwajalein, Marshall Islands
An air-launched Orbital ATK Pegasus XL rocket will deploy NASA’s Ionospheric Connection Explorer (ICON) satellite into orbit. ICON will study the ionosphere, a region of Earth’s upper atmosphere where terrestrial weather meets space weather. Disturbances in the ionosphere triggered by solar storms or weather activity in the lower atmosphere can cause disturbances in GPS navigation and radio transmissions. Delayed from June 15, Nov. 14 and Dec. 8. [Nov. 13]
