Spaceflight Now changed this to November 10, also saw that date a couple other places.

I'm sure it's my fault since I wrote code for it's ground system 7 years ago..................

except that its rocket has been assembled in its MST ahead of schedule like clock work for months on months now and its the satellite's ATMS instrument that is to blame by not passing all of its integrated environmental tests. ATMS issues must be corrected and the satellite retested before it can ship for launch.

Question to those who are "in the know": what's the "hang-time" of those GEM-40 solid motors? They've been sitting vertical since last april.

NOAA’s JPSS-1 Satellite Arrives in California for Launch
Posted on September 5, 2017 at 2:29 pm by Anna Heiney.

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 satellite is scheduled to liftoff later this year atop a United Launch Alliance Delta II rocket.

Next-generation weather satellite shipped to launch base in California

It has been a struggle to reach this point after several technical issues with the satellite kept it in Boulder nearly a year longer than planned.

Launch dates came and went throughout this year while engineers worked through problems with one the weather instruments on the satellite, an onboard computer that was misbehaving and potentially defective capacitors inside the spacecraft that were called into question in an industry-wide alert issued in late June that was a last-minute curveball thrown at the team.

An elusive issue with the Advanced Technology Microwave Sounder instrument, dogging the mission for months, was creating noisy data on several of its channels when heaters were activated. Extensive testing was done to characterize the problem, ultimately requiring removal of the ATMS instrument from the satellite to isolate the cause. Finally, an intermittent cable short within the instrument was deemed the root cause, cable insulation was added and the instrument retested successfully.

One by one, the issues were fixed, a number of suspect capacitors were pulled out and replaced with ones from a good batch, and JPSS 1 was cleared to ship to the launch site.

Officials say a nominal launch processing flow has begun with some reserve days included, should any work take longer than planned.

“The JPSS 1 team has done an incredible job getting this extremely capable satellite prepared for launch and ready to send back quality environmental data soon after it is in orbit,” said Stephen Volz, director of NOAA’s Satellite and Information Service.

The daily launch window lasts just 62 seconds, a tight requirement to sync up the JPSS 1 orbit with the aging Suomi NPP weather observatory that it will replace. Depending on launch day factors, liftoff could be re-targeted for the exact center of the window for optimal performance — at 1:47:35.328 a.m. local time.
