NASA Blog at 10:30 UTC posted: "A news briefing will be held in about 2 1/2 hours to talk about the launch."

So 1pm UTC

Are there common features between the Taurus XL and the Taurus II fairings ? who designs them ? produces them ?

My understanding is that this new post-OCO faring separation system has been flown successfully on Minotaur IV, but I'm not sure if the faring itself is common.

Different fairings on Taurus-3110 and Minotaur-IV

Sad news to wake up to (6am now on the east coast of the US).
However, thanks for covering the launch.
Looking forward to the press briefing.

Does anyone know why the VAFB imaging infrared tracking camera feed was bouncing about like that? A loose cable or something?

Well, it was a failure to separate the fairing but, from what little has been announced so far, it seems to have a different root cause.  IIRC, the OCO failure was caused by an electrical fault that caused the separation system to fail to pressurise.  This time, the system did pressurise (as far as the telemetry told them) but the fairing still didn't separate.

OCO failure was not electrical in nature.

Bolden said he is confident that commercial space firms can deliver.

“At least one has been doing it for more than 20 years,” Bolden said, citing Orbital Sciences, one of several references made during the hearing to the well-established Dulles, Va.-based company.

“I’m not concerned about their ability to deliver,” he said.

Mishaps happen.  Launching things through the atmosphere and out of the gravity well is not easy. Murphy is never on our side, but we also owe it to all of our customers and stakeholders to fully understand the known-unknowns, the unknown-unknowns, and the difference between them.

Condolances to the Glory payload team and OSC Taurus.

Obviously secondary payload of three small research satellites, or CubeSats also lost.  Very disappointing as I looked forward to monitor the cubesats via amateur radio.

A really sad day for the #Glory team and also for earth solar science and research in general, but I hope The Team will be back.

RELEASE: 11-050

NASA'S GLORY SATELLITE FAILS TO REACH ORBIT

WASHINGTON -- NASA's Glory mission launched from Vandenberg Air Force
Base in California Friday at 5:09:45 a.m. EST failed to reach orbit.

Telemetry indicated the fairing, the protective shell atop the Taurus
XL rocket, did not separate as expected about three minutes after
launch.

A press briefing to discuss the Glory launch failure is planned at
Vandenberg for approximately 8:00 a.m. EST. NASA Television will
carry the press conference live at:

The new Earth-observing satellite was intended to improve our
understanding of how the sun and tiny atmospheric particles called
aerosols affect Earth's climate.

I remember thinking at the time when the solutions were proposed that they were just making educated assumptions about root cause without real proof of concept of the failure mode which I suppose was real hard/impossible to do when the evidence was buried in the ocean. Commiserations to all involved.

Just over 10 minutes to the failure presser.

This is going to be heartbreaking.

"It's a very difficult situation."

Outlined the countdown. No anomalies.

Stage 0 was nominal.
Stage 1 ignited, sep.
2:45 seconds - burnout of Stage 1.
Ignition Stage 2.
Six seconds later, expected fairing sep. We didn't see the indication.
Performance loss later on.
Failed to make orbit.
All indications are the satellite and rocket are in the southern Pacific.

"This is a pretty tough night for use. We had a fairing sep failure on OCO.

Conducted an extensive investigation. Fairing sep system root cause. Spent a lot of time redesigning the system. Changed out the initiation system we use on a vehicle we've successfully flown three times.

We thought we had it solved and then we came up against this.

There's a lot of emotion, but doubly so on a return to flight mission like this one.


It's not an understatement to say we're all pretty devestated. Orbital will bounch back with the Taurus vehicle.

Uses a cam shell fairing. Frangible joints. Seps and pistons push the two halves off.

We've used a hot gas system to push the pistons. In the investigation of the OCO failure was the failure to start that hot gas system.

So we redesigned to use a cold gas system. Completely different methord and thought we had that system nailed with three successes.

Right now we're crunching the data, but not enough to tell anymore that the fairing didn't deploy.

Had worked this risk with all levels and thought we had an acceptable level of risk. Clearly we missed something.

We've lost the Glory mission. SMD will continue to contribute to the understanding of the Earth with its 13 missions.

We'll continue to plan the path forward.
