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?
the manufacturing equipment was pulled off the floor when the last first stage booster was completed.

Does that mean the last unbuilt Delta II is scrapped?

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.
If you're happy and you know it,
It's your med's!

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."

Someone here must have inside knowledge given that the thread title now has the launch in Jun(e) 2017.  ;)

NOAA says no later than the second quarter. That could mean as early as March or as late as June.

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.

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.

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.

Tweet from Jeff Foust:
Quote
The launch of NOAA’s next-gen polar-orbiting weather satellite, JPSS-1, has slipped again, to July-September:

SpaceNews: JPSS-1 launch date slips again
Quote
“The main factors delaying the JPSS-1 launch are technical issues discovered during environmental testing of the satellite and the Advanced Technology Microwave Sounder (ATMS) instrument,” [John] Leslie said in a statement.

With future delays I'd bet it'll launch in October-December

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
