Does this set the record for the earliest start of a launch thread?  ;D

Ball Aerospace completes the primary structure for JPSS-1, a follow-on in a series of next generation weather satellites. JPSS-1 is scheduled for launch in early 2017. http://www.ballaerospace.com/page.jsp?page=30&id=555

I was not expecting to see this thread.

There's talk of building and flying a stripped down "gap-filler" satellite before JPSS-1.

According to the US Launch Schedule maintained on NSF Forums by Salo, that would be this SC
November 15 2016 - JPSS Free Flyer 1 (TSIS-1) - Falcon 9 v1.1 (TBD) - Vandenberg

Where do you think I got the launch date for the thread heading?  I tried to find the latest one but if I failed I can correct the date.

Sorry, my post was very unclear.

As you point out, JPSS FF1 is schedule for 2016. Free Flyer 1 is to carry a climate instrument as well as SAR and data relay payloads.

The drawn out nature of JPSS development and the small number of satellites has led an independent reviewer to suggest NOAA build an additional "gap filler" satellite, which they confusingly also refer to as a free flyer. This gap filler satellite would include just the two most critical weather instruments and -ideally- launch before JPSS-1 to cover the gap between S-NPP nominal end of life and JPSS-1 launch. This satellite would also provide coverage if JPSS-1 failed.

Even if the proposed gap filler is built, it's unlikely to launch before JPSS-1 because the instruments will probably barely be ready for JPSS in 2017.

We're furiously working on JPSS-1.  I'm burning weekends and long shifts, as are many of my colleagues.

The Joint Polar Satellite System (JPSS), aka JPSS-1, is taking shape in Boulder, CO. Recently, Ball Aerospace technicians lowered the JPSS-1 spacecraft bus over the propulsion tank prior to final integration with the propulsion module. The satellite is being built for NASA Goddard and NOAA Satellite and Information Service.

CERES Integration

Published on Dec 16, 2014
A Ball technician inspects the CERES instrument prior to the lift harness being attached. The instrument is then moved alongside the spacecraft where it is lifted above the JPSS-1 spacecraft and lowered into place. Once the instrument is secured to the spacecraft, the lift fixture is removed from the CERES instrument. The final shot shows the CERES instrument with its purge cover attached.

I was wondering if these could be the final GEM-40 motors, but I'm not sure if the IceSat 2 launch might follow JPSS 1. 

I agree with your Flickr complaint.  Mediaarchive was easier to use, though Flickr still provides access to the same high resolution images.

there will be some unflown ones as they were batch ordered. Now that the fifth DII did not get a mission and may be built into a structural display after its parts are used as spares. Originally JPSS-2 was to fly on DII before the manufacturer of JPSS-2 was changed which resulted in a change of launcher. The 9 SRM casings were already completed before the DII flight cancelation. That is what I am aware of to date since manufaturing for the two JPSS flights started shortly after NPP launched.

There's one more Delta II carrying ICESat 2 in 2017. There's also enough parts for another Delta II, but ULA has not been able to find a buyer for it.

Could the last unbuilt Delta II be assembled for a museum display like the Titan IVB?

Here's the full album of new processing pictures. Lots of good pictures that give a great sense of scale. I'm always amazed by how comparatively small Delta II is.

Last I recall Rocketdyne was making the Delta/Thor XLT core for these vehicles.   Anyone know if the tooling went to the scrapyard or just storage.   This is my favorite S1 core to play LEGO rockets with.   Sad to see its end in sight.

No, Rocketdyne just made the RS-27 engine, Douglas/MDAC/Boeing/ULA always made the core.

Delta 2 rocket being assembled at Vandenberg for penultimate launch

First stage erected on launch mount today, July 12.
Interstage adapter attached tomorrow.
Nine solid boosters will be hung July 19-27.
Second stage will be hoisted into place July 29.

EDIT: To answer kevin-rf's (and I assume others') question below:
Quote
Lean operations dictated that the on-pad assembly would occur now while workers could break away from their duties on other rockets.

I assume these are ULA employees that will also work the Vandenberg Atlas V launches of WorldView 4 and NROL-79 later this year?

Is it typical to start attacking a Delta II six months before the planned launch? Seems a bit early... I realize Titans have sat on the pad for years waiting for everyone to cross all the i's and dot all the t's, but... But.

Attacking?  Why would you want to attack a rocket -- did it do something bad to you?

Seriously, though, you didn't read the article, did you?  The link is in the post just above yours ... give it a click.  :)

The Delta II will be protected from the elements by the mobile service tower. It is fully enclosed when inside.

That article gives a launch date of 16 March.

"Those issues led NASA and NOAA to delay the JPSS-1 launch, which had been scheduled for Jan. 20 on a United Launch Alliance Delta 2 from Vandenberg Air Force Base in California. That launch is now scheduled for no earlier than March 16. “NOAA and NASA are currently evaluating progress on the ATMS troubleshooting and ground system test and verification to assess the level of risk associated with a commitment to a March 2017 launch date,” Burch said."

At the South Australian Space Forum today it was announced that the Buccaneer Pathfinder cubesat will launch with a NASA weather satellite. This is most likely JPSS 1 as GOES-R is going to the wrong orbit. If Biarri-Point doesn't launch first (its on one of the CRS missions early next year), this will be the first Australian Defence Department satellite to be launched since WRESAT in 1967.

Secondary payloads for the last two DII launches are already announced previously and are already listed on the US Launch Schedule so go check it out.

Secondary payloads for the last two DII launches are already announced previously and are already listed on the US Launch Schedule so go check it out.

Thanks. I see that the payloads were first listed on 20 August, but no reference is given. The secondary payloads are

Buccaneer RMM
CP 7
EagleSat 1
Fox 1B (RadFxSat)
MakerSat 0
MiRaTA

ELanA XIV lists EagleSat 1, RadFxSat and MiRaTA on the NASA website (Golden Eagle 1 is also listed, but that mission has been cancelled). Are CP 7 and MakerSat 0 part of the ELanA program? The NASA list has MakerSat (no number) flying on ELanA XX and only lists CP 5 and CP 9.

NOAA says no later than the second quarter......

http://www.jpss.noaa.gov/launch_schedule.html
of the fiscal year so, as early as January or as late as March.

Don't wager any money on March.  I'm moving my RV out to CA shortly, but that's because I'm going to visit the central coast at least a weekend or so every month until we ship.  I'm hoping to get a few more launch observation days in there as well.

The title date is closer to realistic in my opinion.  I can't publicly state my wager date.  It's in 2017 at least...

Here's hoping that since CA just voted to legalize cannabis, I won't get pulled over constantly just for the sin of having Colorado plates... and I don't even touch the stuff...

CP-7 is not part of ELaNa, but  MakerSat 0 is. I was notified from the  MakerSat team, that their launch opportunity has been moved up to this launch.

RadFxSat (Fox-1B) Launch Moved to Late August

01/16/2017
AMSAT reports that the launch date for RadFxSat (Fox-1B) has been moved to August 29, 2017. RadFxSat is one of four CubeSats making up the NASA ELaNa XIV mission, riding as secondary payloads aboard the Joint Polar Satellite System JPSS-1 mission.

RadFxSat features the Fox-1 style Amateur Radio FM U/V repeater, with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry will be downlinked via the “DUV” subaudible telemetry stream and can be decoded with the FoxTelem software.

JPSS-1 will launch on a Delta II from Vandenberg Air Force Base, California. RadFxSat is a partnership with Vanderbilt University ISDE and hosts four payloads for the study of radiation effects on commercial off-the-shelf components.

RadFxSat construction and testing was completed in the fourth quarter of 2016, and the CubeSat is currently in clean storage at Fox Labs, awaiting delivery and integration, now scheduled for June. — AMSAT News Service via AMSAT Vice President-Engineering Jerry Buxton, N0JY

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.

For more information, please visit www.jpss.noaa.gov.

Next-generation weather satellite shipped to launch base in California

Quote
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.

Quote
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.
