T+plus 8 minutes, 30 seconds. About two minutes remain in this first burn by the hypergolic second stage to deliver JPSS-1 into polar orbit.

T+plus 12 minutes: We're now in a 40-minute quiescent coast period for the Delta II to arrive in the proper position for its next engine firing over the southwestern Indian Ocean

Опубликовано: 18 нояб. 2017 г.

United Launch Alliance have successfully launched the penultimate Delta II rocket today at UTC, November 18th 2017, from Space Launch Complex 2W at Vandenberg Air Force Base. The rocket carried the JPSS-1 weather satellite for NASA into orbit. There is only one more Delta II launch scheduled for next year, parts for a final Delta II remains but has no customer and is unlikely to launch.

The Delta 2's second stage is being placed into a "barbecue roll" to ensure equal temperatures on the vehicle as it remains in a coast phase before engine restart.

#DeltaII is taking #JPSS1 to an orbit with a Local Time of Ascending Node (LTAN) of 1:30 p.m. (1330). This means that every time the satellite crosses from the Southern Hemisphere to the Northern Hemisphere (at equator), it is 1:30 p.m. on the ground below it.

#DeltaII is taking #JPSS1 to a sun-synchronous orbit. For the altitude (~450 nmi) & inclination (98.7 deg), the orbit plane maintains the same relative angle to the sun and keeps the Local Time of the Ascending Node at 1:30 p.m.

We are five minutes away from the restart of the hypergolic-fueled second stage engine. The second burn will be ~25 seconds long. #DeltaII #JPSS1
