NASA's Orbiting Carbon Observatory Mission Fails 325
jw3 writes "The NASA Orbiting Carbon Observatory scheduled for launch today has failed its mission: the payload fairing failed to separate and the launch managers declared a contingency. George Diller, NASA launch commentator, said, 'It either did not separate or did not separate in the way that it should, but at any rate we're still trying to evaluate exactly what the status of the spacecraft is at this point.'" Update: 02/24 14:17 GMT by T : Reader fadethepolice points out a Reuters report which says that the craft crashed into the ocean just short of Antarctica.

I worked on the instrument team for OCO from 1999-2004, and on similar instruments in the past. Yes, it is much easier to build another, but unfortunately, it's not really that much cheaper from a mission point of view, since the launch vehicle and satellite buss are a large fraction of the cost, and most of that is already incremental cost, not NRE. Usually, NASA considers the risk of launch failure and requires contractors to keep records adequate to build another on an incremental basis.
One other cost factor is the ground segment -- the mission operations center and the data analysis facility. As I understood it five years ago, there were plans to build a rather large data center to crunch all the spectrometry data that OCO would have sent down. That didn't get sunk to the bottom of the ocean.
And while I don't think anyone is "pissed," the mission and instrument teams are probably quite dejected. Especially Dr. Crisp, the principal investigator. That was his baby.
There is a good chance that NASA may still "do it over" however, 1) because of the reduced "incremental" cost, and 2) to support Pres. Obama's environmental policy.

The CO2 causing warming myth is nothing but media and political hype...
Given your statements below, I don't think your knowledge of this subject warrants such bold assertions.
Looking at the data, it's clear to see that CO2 increase follows, not leads, an increase in temperature.
In the glacial-interglacial cycle, this is true, but it's also not a surprise; it's a prediction of Milankovitch theory, which existed before any lags or leads were ever measured in the data. It also does not imply that CO2 has no effect on temperature.
If there is causation (thus far only some correlation has been established), then the rise in CO2 is caused by the increase in temperature, not the other way around.
It's both. According to the Milankovitch theory, orbital variations cause shifts in temperature. These temperature shifts cause changes in the carbon cycle, which alters CO2 levels. The altered CO2 levels in turn amplify the original orbital temperature change.
If you leave the CO2 feedback part of that process out, then you can't explain the amplitude of the glacial-interglacial cycles anymore, and it's unclear whether you can even, say, trigger a glaciation without the contribution of CO2 drawdown.
For those that support the CO2 driving the increase, I've yet to see how the climate models explain how the temperature 450 million years ago was colder than it has ever been in the last half billion years, but the CO2 levels were 10 times what we have today.
You could start here [agu.org], here [sciencedirect.com], or here [gsapubs.org].
And for those arguing that human activity is driving the increase, why does the rate of increase vary so greatly (particularly looking at the significant decrease in rate during 1991-1993) despite the consistent growth of human CO2 producing activities.
Human emissions don't vary smoothly, nor does the terrestrial carbon sink, which has quite a bit of interannual variability due to climatic effects on, e.g., photosynthesis and heterotrophic respiration. Just as a guess, I'd look first at the collapse of the Soviet Union (assuming there is a significant slowdown during those years, which I haven't checked).
As for human activity driving the observed increase, that's been proven beyond all reasonable doubt. Nobody seriously argues that part of the story anymore; there are about six independent lines of evidence, including historic emissions data, measurements of cumulative ocean carbon and air-sea CO2 fluxes, measurements of terrestrial CO2 fluxes, modeling of said fluxes, shifts in carbon isotope ratios in air and sea, and changes in the CO2/O2 ratio of the atmosphere.
However, it seems that deforestation along with ever expanding cities with concrete and asphalt that absorb and radiate heat make an even better explanation than CO2,
Urban heat islands don't explain the warming. CIties are a small fraction of the Earth's surface and the amount of heat they radiate, even if you take into account subsidiary albedo changes, isn't big enough to account for the warming. Land use change is a good idea in principle (e.g., due to surface albedo changes, alterations in evapotranspiration, etc.), because it's more widespread. But it still falls well short in magnitude: in some locations it has a substantial effect on local temperatures, but simply doesn't explain the global amount or spatial distribution of surface warming.

Disregarding the melodrama of the GP, I know of several good reasons to measure CO_2 throughout the atmosphere and I'm sure the actual scientists know some more.
The atmosphere is actually quite complex, with different layers and surprisingly little mixing between different levels. I mostly know about the southern ozone hole, being from New Zealand which is still pretty fucked by it. The CFCs which destroyed the ozone were released all over the world - mostly in the northern hemisphere even, since that's where the majority of the population is. However the southern polar vortex is the major cause of mixing between the lower and upper atmosphere, so as the CFCs drifted down to Antarctica they were ejected to the upper atmosphere - where the ozone layer is - and reacted with the ozone there eating a big hole in it.
Similarly, CO_2 is released a ground level, but what effect does it have in different layers of the atmosphere? How fast does distribution to different layers occur? With a satellite which could measure this we could build up a body of data correlating CO_2 concentrations in different parts of the atmosphere with climate change and characterise the movement of CO_2 concentrations through the system, giving us an idea of the lead-in time for CO_2 climate change.
As for why CO_2 is important: it's one variable in a complex equation but it's the one we're directly fiddling with.

"OCO's spectrometer will provide greater sensitivity on carbon dioxide measurements but is unable to detect methane. GOSAT's orbit is designed to bring the satellite over the same location more often, allowing the craft's lower resolution instrument to create a new global map every three days."
The real key is whether the Japanese satellite was going to take A SINGLE MEASUREMENT for each data point (that's what appears to be in the articles I've read) or get a reading of the entire atmospheric column (providing a vertical graph of the carbon dioxide level was for each location). NASA had a specific set of three instruments designed to do just that . If the Japanese satellite does that as well then you're probably right I'm overreacting since a three fold drop in resolution is probably still good enough. If not, then there is a vast difference in not just the amount but the TYPE of data returned.

I pointed this out in another response, but I just want to emphasize that OCO would have measured the column average CO2, not the whole vertical profile. You could potentially think about clever spectral analysis algorithms to tease out some of the rough vertical structure, but it wasn't designed to do that.

We don't need OCO to attribute warming to humans. OCO would have improved our understanding of and ability to predict the terrestrial and ocean carbon sinks. This is important to determine how severe global warming may become in the future (since it modifies the amount of CO2 which remains in the atmosphere). Still, to first order the fact remains that regardless of changes in sinks, we still ought to be doing more mitigation than we are.

The 986-pound (447-kg) spacecraft was tucked inside a clamshell-like shroud to protect it during the ride into space. But three minutes into the flight, the cover failed to separate as expected, dooming the mission.
"As a direct result of carrying that extra weight we could not make orbit," said John Brunschwyler, the Taurus program manager with manufacturer Orbital Sciences Corp.
The spacecraft, also built by Orbital Sciences, fell back to Earth, splashing down into the southern Pacific Ocean near Antarctica.

So luckily it had a softer landing by hitting water instead of some of that hard ice.

It didn't fail its mission, it failed its launch. If its mission was to launch then it failed its mission. However, its mission was to monitor CO2, which it never got a chance to begin.

Did it fail because the global warming zealots deep down knew they were full of sh*t and sabotaged the satellite to keep the hoax going? --- Or --- Did it fail because the anti-global-warming crew didn't want more "data" to be added to the debate? Personally, I would laugh my ass off if the satellite used a nuclear power source. That's irony.

That was _last_ season. This season we'll be monitoring CO2 levels from space. Also planned are mapping cow farts via Google maps mashups and planned for season three: a Google maps/Zillow mashup showing the exact number of humans on the African sub-continent who could have survived for more than a month on the energy wasted through the carbon footprint of every house in America. That's right. Search for your house in Zillow and be instantly notified of how many people died so you could watch the superbowlcrapgame in comfort and style. Additional efforts by season 2 sponsor AT&T will allow you to track high CO2 outputters via GPS in their phones. Season 3 sponsors AT&T and General Dynamics plan to bring you HCO European edition via UAV. That's right, each week we'll allow one Republican Evangelical to get "up close and personal" with one of Europe's most prolific CO2 outputters via UAV. The fun never ends.
Thanks to the FTC, EPA, and several other federal agencies, there will be no tax credits, carbon credits, alternative energies, or in fact any plan to reduce CO2 outputs. We just want you to see what you could have done to help the world. It's a feel better move, change you can relax with.

What actually happened is that the aliens hiding behind the moon realized we'd notice their trail of hothouse gases from terraforming equipment on the moon, and have disabled the rocket to ensure the satellite does not do its job.
