The launch of a United Launch Alliance Delta II rocket carrying the Joint Polar Satellite System-1 mission for NASA and NOAA is confirmed on the Western Range for Saturday, Nov. 18. The launch time is 1:47 a.m. PST (4:47 a.m. EST).
NOAA’s Joint Polar Satellite System-1 spacecraft will launch aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 at California’s Vandenberg Air Force Base. Launch managers are working to determine a launch date after today’s planned liftoff was scrubbed due to upper-level winds.
The launch of a United Launch Alliance Delta II carrying the JPSS-1 mission for NASA and NOAA was scrubbed today due to a red range and a late launch vehicle alarm. Due to the short window there was insufficient time to fully coordinate a resolution.
The launch is planned for Wednesday, Nov. 15, from Space Launch Complex 2 at Vandenberg Air Force Base, California. The launch time is 1:47 a.m. PT.
The tower at Space Launch Complex 2 was rolled back late yesterday, leaving the United Launch Alliance Delta II rocket and NOAA’s JPSS-1 satellite poised for liftoff from Vandenberg Air Force Base in California.
The ULA Delta II rocket carrying the JPSS-1 mission for NASA and NOAA is delayed due to a faulty battery. The delay allows the team time to replace the battery on the Delta II booster. The vehicle and spacecraft remain stable. Launch of the JPSS-1 mission is scheduled for no earlier than Tuesday, Nov. 14.
Mission and launch officials for NOAA’s Joint Polar Satellite System-1 (JPSS-1) have convened today at Vandenberg Air Force Base in California in preparation for the satellite’s upcoming launch aboard a United Launch Alliance Delta II rocket.
During its time in the Astrotech Payload Processing Facility, JPSS-1 has undergone a series of routine prelaunch tests and checkouts, followed by mating to the Payload Attach Fitting and transport to the launch pad, where the Delta II rocket stood already assembled. The spacecraft then was hoisted into position atop the rocket. Also installed were a trio of Poly-Picosat Orbital Deployers, or P-PODs, which will deploy a host of small CubeSat payloads after the JPSS-1 satellite is released to begin its mission. The entire payload has been enclosed within the two-piece fairing that will protect it during the climb to space.
Orbital ATK’s Pegasus XL rocket is being prepared to launch NASA’s Ionospheric Connection Explorer, or ICON mission. The rocket is being prepared in a facility at Vandenberg Air Force Base (VAFB) in California.
The rocket’s second and third stages, first stage motor and wing arrived at VAFB and were transported to Building 1555 for processing.
ICON will launch aboard Pegasus from the Kwajalein Atoll, part of the Republic of the Marshall Islands in the Pacific Ocean, on Dec. 9, 2017 (in the continental United States the launch date is Dec. 8).
ICON will study the frontier of space — the dynamic zone high in Earth’s atmosphere where terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth’s space environment and pave the way for mitigating its effects on our technology, communications systems and society.
NOAA’s Joint Polar Satellite System-1 spacecraft has been removed from its shipping container in the Astrotech Payload Processing Facility at Vandenberg Air Force Base in California, where it is being prepared for its upcoming launch aboard a United Launch Alliance Delta II rocket.
The JPSS-1 satellite will go through a series of routine inspections, checkouts and testing before it is sealed inside the payload fairing and placed atop the Delta II rocket, already standing at Space Launch Complex-2W. Launch remains scheduled for Nov. 10.
NOAA’s Joint Polar Satellite System-1 (JPSS-1) satellite arrived at Vandenberg Air Force Base in California on Sept. 1, 2017, to begin preparations for a November launch.
After its arrival, the JPSS-1 spacecraft was pulled from its shipping container, and is being prepared for encapsulation on top of the United Launch Alliance Delta II rocket that will take it to its polar orbit at an altitude of 512 miles (824 km) above Earth. JPSS-1 is scheduled for launch from Vandenberg’s Space Launch Complex-2 on Nov. 10 at 1:47 a.m. PST.
NOAA partnered with NASA to implement the JPSS series of U.S. civilian polar-orbiting environmental remote sensing satellites and sensors. JPSS-1 has a seven-year design life and is the first in a series of NOAA’s four next-generation, polar-orbiting weather satellites.

The constellation of satellites charged with maintaining critical communications between NASA’s Space Network and Earth-orbiting spacecraft is about to be expanded by one.
Joining the Tracking and Data Relay Satellite (TDRS) System is TDRS-M, the third and final in a series of third-generation TDRS spacecraft that have taken their places in orbit in recent years. TDRS-M launched this morning aboard a United Launch Alliance (ULA) Atlas V rocket with a liftoff at 8:29 a.m. EDT from Cape Canaveral Air Force Station’s Space Launch Complex 41.

With light winds, few clouds and temperatures in the low 80s, weather posed no threat to launch. The countdown proceeded smoothly throughout the early morning hours and into propellant-loading operations, when engineers noted an issue with the Centaur upper stage’s liquid oxygen (LOX) chilldown system.
“As we were chilling the Centaur engine down, we noticed one of the chilldown parameters on the thermal conditioning for the LOX side was not quite getting cold enough” in time to permit liftoff at 8:03 a.m., when the 40-minute launch window opened, NASA Launch Manager Tim Dunn explained.

TDRS-M’s predecessors, TDRS-K and TDRS-L, also launched on Atlas V rockets from the same launch complex in January 2013 and January 2014, respectively. Today’s launch marked the 72nd liftoff of an Atlas V.
More than an hour and a half after launch, the TDRS-M spacecraft separated from the rocket’s Centaur upper stage, heralding the end of the launch effort and the mission’s beginning. Following several months of calibration and testing, TDRS-M will be renamed TDRS-13, and it will be eligible to begin supporting NASA’s Space Network.
“Spacecraft separation is the best part of the launch campaign,” Dunn said. “So many hours are put into getting to this exact point when you know you have a healthy satellite that just separated from the launch vehicle, about to go do its intended mission.”
