ULA Delta II set to conduct penultimate launch with JPSS-1

The mobile service tower at Space Launch Complex 2-West was rolled away from the Delta 2 rocket and into launch position a few hours ago, setting the stage for an overnight countdown targeting liftoff at 1:47:02 a.m. PST (4:47:02 a.m. EST; 0947:02 GMT).

Спойлер

The moveable gantry, painted in blue-green to match the Delta 2, stands 177 feet (54 meters) tall and was used to assemble the launch vehicle and hoist the JPSS 1 spacecraft atop the rocket. It also houses a climate-controlled clean room for the satellite payload and protects the Delta 2 launcher from weather conditions at the seaside launch complex.

The countdown will come out of a built-in hold at T-minus 150 minutes at 10:47 p.m. PST (1:47 a.m. EST). A few minutes later, the Delta 2 launch team at Vandenberg will begin activating the rocket's guidance computer, followed by the start of propellant loading in the rocket's first stage.

The Delta 2's upper stage was filled with its mix of Aerozine 50 and nitrogen tetroxide propellants earlier in the launch campaign, and the nine strap-on boosters have their solid fuel pre-packed before attachment to the base of the rocket.

In 2017, the National Oceanic and Atmospheric Administration (NOAA), with the support of their partners at The National Aeronautics and Space Administration (NASA), will launch the JPSS-1 satellite, the first operational satellite in NOAA's next generation polar-orbiting satellite system. This video takes you inside the world of JPSS-1, providing a look at some of the satellite's incredible instruments and explaining its journey to space. Join us as we see it off on its mission to continue vital contributions to United States weather forecasting!

Photos: Delta 2 rocket revealed after mobile gantry rollback
November 14, 2017 Stephen Clark

Ground crews at Vandenberg Air Force Base in California retracted a mobile gantry away from the Delta 2 rocket Monday afternoon, revealing the 128-foot-tall (39-meter) booster on its launch pad awaiting liftoff with a new polar-orbiting weather observatory.

The United Launch Alliance Delta 2 rocket is set for blastoff at 1:47:02 a.m. PST (4:47:02 a.m. EST; 0947:02 GMT) Tuesday with the first spacecraft in NOAA's Joint Polar Satellite System. JPSS 1 will go into orbit around 500 miles (800 kilometers) high and use five instruments to measure temperature and humidity in the atmosphere, solar radiation reflected off the Earth, ozone health, and other key measurements to aid weather forecasters.

Fitted with nine strap-on solid rocket boosters made by Orbital ATK and a first stage RS-27A engine and second stage AJ10-118K engine, both from Aerojet Rocketdyne, the Delta 2 rocket is poised for its 154th mission Tuesday. One more Delta 2 launch is planned in late 2018 before ULA retires the workhorse rocket.

The team has been polled and all stations are ready for the countdown to launch #DeltaII and #JPSS1 tonight from California for @NOAA and @NASA

The 3-hour countdown sequence has been initiated for launch of the Delta II from Vandenberg Air Force Base in California with #JPSS1

Spaceflight101 LIVE‏ @S101_Live 4 мин. назад

T-2 Hours 30 Minutes & Counting [L-3 Hours] – Clocks are ticking as #DeltaII Terminal Countdown Operations are started by the launch team. Next is the activation of the Redundant Inertial Flight Control Assembly (RIFCA) for detailed pre-launch checks.

11/14/2017 09:51

After a poll of the Delta 2 launch team turned up no constraints, the countdown has resumed following a one hour built-in hold.

Clocks began ticking from T-minus 150 minutes at 10:47 p.m. PST (1:47 a.m. EST; 0647 GMT)
During the three-hour countdown sequence, ULA's launch team will switch on the Delta 2's guidance computer, pressurize helium and nitrogen tanks aboard the rocket, load liquid propellants into the rocket, test the booster's flight termination system and conduct steering checks on the first and second stage engines.

Two more built-in holds are planned in the countdown at T-minus 15 minutes and T-minus 4 minutes, first for 20 minutes and then for 10 minutes. After a final poll of the launch team, the terminal countdown will resume at T-minus 4 minutes and continue until liftoff.

JPSS-1 Launch Team

NASA's Launch Services Program gives the 'go' for launch!

The launch team members assemble at their computers and communication consoles about three to four hours before launch. The NASA launch manager is the highest authority during the countdown and provides NASA's "go/no-go" decision to the mission director. Before liftoff, the launch manager checks with the launch team to make sure all the criteria are met and that the payload and rocket are ready to go.

Omar Baez, NASA Launch Manager (NLM)
 The launch manager ensures that the countdown and launch decision processes are properly followed. The launch manager polls the launch team before passing along a "go/no-go" decision to the mission director.

Tom Reinarts, NASA Chief Engineer (NASA CE)
 The chief engineer is responsible for advising the launch manager of the launch vehicle's engineering and analysis status for launch.

Bruce Reid, Mission Manager (NASA MM)
 The mission manager assesses the launch service and spacecraft readiness ahead of launch.
