NASA Briefing on New Mars Finding This Afternoon

ipsender writes with a NASA announcement: "NASA will host a news briefing on Thursday, Aug. 4, at 11 a.m. PDT (2 p.m. EDT) about a significant new Mars science finding. The briefing will be held at NASA Headquarters in Washington. The new finding is based on observations from NASA's Mars Reconnaissance Orbiter, which has been orbiting the Red Planet since 2006." You can catch the briefing online at the NASA TV site.

...okay, so we won't see a Zig.

On a more serious note though, I actually hope to Heaven they present something insanely fascinating to the general public - enough to kick the government in the ass and get Mars human exploration seriously going.

Sadly, I suspect it'll be something only of use to some niche of geologists.

Saturn's moon Titan has a thick atmosphere (acutal ground pic). It also has gravity low enough that if a person could strap on a pair of wings, they could fly and more oil than the entire planet.

Re:In AD 2101, war was beginning...

[geekoid]

You need to ask yourself: How are we finding out about the briefing? Is it from someone who watches every minutia from NASA? then don't hold your breath. If it's from someplace more accessible to the general public, then MAYBE i'ts a big deal the general public...whether or not the general public understands it's impact immediately is a different question.

Lisa Pratt is involved, so my hopes are high the found evidence of life.

How come perfectly normal people always wanna swing it this way and act like you're a warhawk just because you're not interested in spending on something science related.

I mean, why don't we send astronauts to Somalia with beef jerky instead, then?

Re:In AD 2101, war was beginning...

[Anonymous Coward]

They're assuming that because you're whining about spending "billions" on it, when the total money spent on the entire space program (from which we actually do get productive returns that improve the general quality of life on earth) is less than one percent the amount spent on military action. If it's the money you're upset about, you should be re-directing your complaints. If it's the "people having hope for the future being better than the shit-hole of a present that we live in" that you're angry about, you're a short-sighted idiot.

Frankly, by assuming you're a violence obsessed warhawk who wants to shoot and blow things up, they're giving you the benefit of the doubt, and regarding you as a better person than you probably actually are.

Re:In AD 2101, war was beginning...

[SoothingMist]

The whole thing sounds like a desperate attempt by NASA to grab favorable attention. Having watched the decline of NASA over the last few decades, my feeling is that NASA needs a mission to which they are held accountable, with no excuses accepted. "Missions to Mars" and "Manned Moon Stations" are not relevant to Earth's needs. They need a mission such as developing and demonstrating space-generated energy with transmission to earth-based distribution stations. They have already shown that they can not cost-electively build, maintain, and resupply a relatively near-orbit space station nor build and evolve a fleet of taxis to and from space.

Re:In AD 2101, war was beginning...

[camperdave]

They have already shown that they can not cost-electively build, maintain, and resupply a relatively near-orbit space station nor build and evolve a fleet of taxis to and from space.

They never got the money or the free hand that they needed to try. NASA has had plans to replace the shuttle for at least 20 years. However, every budget was loaded down with caveats and conditions (eg. must use ATK solids, must use suppliers from every state, current contracts for shuttle parts must be maintained).

Re:In AD 2101, war was beginning...

[Anonymous Coward]

I was once the aide to a former NASA GS-15, a co-inventor of the power transistor. He said he left NASA because they changed from a technical organization into a marketing organization. Another good example of NASA's decline is their magazine, NASA Tech Briefs. This used to be a very technical magazine. One could use a bingo card to get all manner of detailed technical documents and software related to the articles. Now that magazine is little more than an advertising rag for NASA contractors and suppliers. Technical details and software are owned by the contractors after the American people already paid to have the research performed.

Yet, I must agree that our Government does put pork above accomplishment in order to buy votes. That is one of the reasons for America's continuing decline. Both parties engage in this despicable practice.

Slightly harder than adding 4 hours to EDT to come up with GMT (which incidentally has the advantage of being correct).

Also, he got his offset wrong. A quick lookup tells me EDT is actually 4 hours behind GMT.

Kind of obnoxious for us to think that the center for UNIVERSAL coordinated time is somehow linked to the UK, isn't it? Perhaps the folks at alpha centari would have something to say about having to add/subtract a couple thousand years to calculate the correct time for them to listen in to this announcement...

Re:timezones, schmzones

[Alioth]

Adding 6 hours to EDT won't give you GMT (or UTC), it'll give you CEST (Central European Summer Time).

EDT is UTC-4, not UTC-6.

Re:timezones, schmzones

[Grishnakh]

Everyone knows their GMT offset, so why not give those times?

Sorry, but I think if you did a poll of the general public to find out how many know their GMT offset, it'd be pathetically low. Even among Slashdotters I wouldn't have much hope, since that other poster thought that EST was GMT-6 (it's GMT-5).

Everyone should know their GMT offset, as it would help greatly when dealing with time zones, which is something pretty common now with anyone who's a professional and has to travel, or talk to colleagues in offices located in other time zones.

It'd also help if people understood what Daylight Saving Time is, and the difference between *DT and *ST, and the fact that not every place uses DST. I'm in Arizona, and colleagues in eastern states are constantly getting confused because my time (MST) is currently the same as PDT, even when there's a state right next-door to them (Indiana) which also had large portions that did not follow DST (up until 2006). Most people don't even seem to realize that they are not, for instance, following EST, but EDT, and if you ask them what their time zone is, they'll say "EST" even though I don't know any states in the US that are on EST anymore.

The announcement about the briefing came from JPL, which is on PDT and the briefing is being held in Washington, DC, which is on EDT. So TFA gives both those times. The summary quotes the times given in TFA. I just wish NASA would starting using decimal-based time instead.

Methane. It's going to be something about methane. Look at all the geologists on the briefing panel;

The briefing panelists are:
-- Philip Christensen, geophysicist, Arizona State University, Tempe
-- Colin Dundas, research geologist, U.S. Geological Survey, Flagstaff, Ariz.
-- Alfred McEwen, planetary geologist, University of Arizona, Tucson
-- Michael Meyer, Mars Exploration Program lead scientist, NASA Headquarters
-- Lisa Pratt, biogeochemist, Indiana University, Bloomington

Re:My guess -

Re:My guess -

Re:My guess -

No, it is indicative of the presence of methane.

Re:My guess -

ABSOLUTELY!
Now give us that money so we can send stuff on there to check this out.

Re:My guess -

[HappyHead]

Methane, Large sources of easily available water, or Oil. One of those three are the most likely.

Considering the focus on geology, it's also possible they've found a surface deposit of some rare earths minerals (such as those which are currently exported only by China), though you're right, methane is probably the most likely, and while geologists studying Mars might find it interesting, it's not nearly as significant to the rest of the human race.

Re:My guess -

[squidflakes]

Humm... looking at the biographies of the scientists involved, I'm going to guess something about water, ice, and life.

Re:My guess -

[Darth Snowshoe]

They have certainly found methane on Mars, and so far can't conclusively explain where it's coming from, or its periodic nature;

http://www.nasa.gov/mission_pages/mars/news/marsmethane.html

Here's the good bit;

"Methane is quickly destroyed in the Martian atmosphere in a variety of ways, so our discovery of substantial plumes of methane in the northern hemisphere of Mars in 2003 indicates some ongoing process is releasing the gas," said Dr. Michael Mumma of NASA's Goddard Space Flight Center [...]

Take a look at Lisa Pratt, among today's panelists - her IU home page is kind of a big clue;

Hmm, let's see ...

So, it looks like Coors has officially sponsored the Mars expedition and will be using official NASA footage from the rovers for their next stupid commercial?

Re:My guess -

[MightyMartian]

I believe it could also be explained by other active geological processes. Maybe not as exciting as organisms, but still, considering the view right now is that Mars is a geologically dead planet, so it would be at least moderately interesting to find out that there are geological processes still ongoing. It also could provide yet another possible place for life to exist.

Re:My guess -

[Narcocide]

Only probably, and that's only based on what we currently know about necessary components for life. Remember that not so very long ago we didn't even know that chemosynthesis was possible.

Re:My guess -

I'm hoping oil then, that should get us to Mars in a hurry!

Re:My guess -

[SnarfQuest]

Then it must be about Global Warming caused by Man. Those two SUV's they've been running all over the place has destabilized the planet, and runaway greenhouse methane has caused devistating thermal effects. The only chance Mars has, is if George W Bush signes the Kyoto treaty. But republicans hate martians, as proved by the fact that they pay Slim Whitman records.

Re:My guess -

[gtall]

So you are saying cows are involved in this?

Re:My guess -

[pz]

Lisa Pratt studies sulfur and specifically biological sulfur with respect to the surface of Mars. Check out her lab's web page:

http://geology.indiana.edu/pratt/

Here's a list of her research interests from that site:

Geomicrobiology of sulfate-reducing microorganisms
Biotic and abiotic fractionation of sulfur isotopes in modern and ancient oceans and lakes
Influence of wildfire on carbon isotopic excursions during the Cretaceous
Fate of complex organic molecules on the surface of Mars

As far as I can tell from that list, Dr. Pratt is the only hard scientist. The others are more involved in managing the program (Meyer) or designing the instruments (Christensen, Dundas, McEwen). Interestingly, there are no post-docs or graduate students listed, and they would have been the lead investigators doing the actual work -- perhaps this is a reaction to the Felisa Wolfe-Simon snafu? I'm not familiar with the field, though, so much of this is speculation from 2 minutes' work with Google. Take it for what it's worth.

Re:My guess -

[Anonymous Coward]

Not unless you think the atmosphere of, say, Neptune indicates life. Methane can form from biological processes or non-biological processes. Methane on Earth is most abundant from biological sources, but methane is also expelled from volcanoes, among other places. The Fischer-Tropsch process is one of the reactions that can produce methane non-biologically.

Re:My guess -

[IrquiM]

Oil!

Re:My guess -

[mbone]

I don't think MRO has anything on it to detect methane. Maybe they could do it with CRISM (IR spectrometer), but there is nobody from CRISM on the panel.

Someone who is on the panel is Lisa Pratt who is "specializing on the fate of complex organic molecules on the surface of Mars.," and also Alfred McEwen, the principal investigator of the High Resolution Imaging Science Experiment (HiRISE). This says to me that they found something interesting on the surface, maybe something looking like tar or oil, or maybe something changing with time.

Re:My guess -

[Anonymous Coward]

You could have just

Geologists -> Beer

Re:My guess -

Oil? As in petroleum? Seeing as oil is an organic byproduct, that would be orders of magnitude more significant (and less likely) than large sources of water.

Rare earth metals aren't "rare". China only have the correct conditions for economic mining at the current prices. If the prices rises, it becomes economical (again, because it used to be so) to mine then in other places, including the United States. I really doubt that rare earth "deposits" on Mars would be newsworthy.

If Oil is only possible as an organic byproduct, then you have just discovered proof positive of life on Titan. Congratulations - you should call a press conference right away!

Oil? Obviously you must be joking.

Oh, and rare earths aren't; rare earth ores are somewhat more so, but that is more a function of economics than anything else (an ore is an economically recoverable mineral resource; there are ample rare earth mineral resources around Earth, just not generally economic to recover - but that depends entirely on the price). No amount of rare earths on Mars are going to mean anything to anybody in economic terms until long after people are living there, if ever.

Re:My guess -

[Grishnakh]

Oil isn't going to help anyone on Mars. The atmosphere is 95% carbon dioxide, with only trace amounts of oxygen, so you can't burn it there. The only reason oil is so useful here is because of our abundance of oxygen in the atmosphere.

Of course, you could build giant oil-tanker spaceships to transport it back to earth, but I imagine the costs of that would be far, far greater than simply 1) continuing to exploit the oil we have here and 2) developing space-based solar power or some other exotic power source.

Maybe they could start terraforming Mars; with all that CO2, maybe they could plant trees to start converting the CO2 to O2. But Mars' atmosphere is very, very thin compared to ours, so that probably wouldn't work either (Mars' atmosphere has a peak pressure, at the lowest elevations, of only 0.1675 psi, whereas on Earth, our average pressure is 14.69 psi). Unless we could figure out a way of beefing up the atmosphere, we'd probably have better success terraforming Venus. It's the same size and gravity as Earth, and has a very thick atmosphere. We just need to figure out how to thin it out some, stop the runaway greenhouse effect, and convert it to an Earth-like atmosphere. That's probably easier than trying to figure out how to get a tiny planet (about 1/3 the gravity of Earth, 1/10 the mass) to hang onto enough atmosphere to work with.

Re:My guess -

Grad students and post-docs very rarely get trotted out for P.R. work like this. It'll be the PI in whose lab the work took place. Wolfe-Simon was the exception (and was apparently working with the sort of independence most post-docs would KILL for prior to that).

Re:My guess -

Re:My guess -

[DerekLyons]

Translation: It's only important if you're getting the test tubes dirty. The rest of it isn't 'real' science. After all, having a Master's in oceanography and specializing in research on extremophiles (Meyer) is meaningless. Dr Christensen's 11 page CV (PDF link) showing 30 odd years of work involving Martian geology - beneath consideration! They're 'just' managers and instrument designers... Heck, anyone could do that.
 

Interestingly, there are no post-docs or graduate students listed, and they would have been the lead investigators doing the actual work -- perhaps this is a reaction to the Felisa Wolfe-Simon snafu?

Um, no. Post-docs and graduate students aren't listed precisely because post-docs and graduate students *aren't* lead investigators on a major project like this. (And what constitutes 'actual' work is largely a matter of bias rather than of fact anyhow.)
 
Seriously, you have a deeply flawed and juvenile vision of how large, complex, and long running scientific investigations like this are conducted. It's a team effort and the managers and instrument designers are just as important as the 'hard' scientists.

Having studied with Phil Christensen, I can tell you he's more "hard science" than 99% of geologists. Especially when it comes to geologic interpretations of remotely sensed data, because his command of the physics behind EM interactions with geologic materials is second to none. If Phil is part of the announcement, it is definitely about something they've found, there's geology involved, and very possibly water.

Re:My guess -

[shugah]

Said the rhyme, did the crime.

Re:My guess -

[pz]

You're missing the point entirely and making baseless accusations.

The point was to try and divine the nature of the announcement. The list of speakers includes the head of the entire observation project, people who were leading the instrument design, and the head of a lab that does nothing but science. Chances are the announcement is going to involve the theme of the hard science lab.

(My lab does both instrument design and basic science. My dissertation had two major sections, the first labelled "Technology" that contained a description of a novel data collection method, and the second labelled "Science" that contained the results from applying said method. Given that I've spent my entire adult life in academia, have been part of large projects, and head my own lab now, I'm pretty certain I understand quite well what's involved, and the relative importance of instrument building and investigation.)

While lab heads are clearly important, and I say this in part with the vested interests of being the head of a lab, the bulk of the non-administrative work on any project is done by graduate students and post-docs. That's why their names come first on publications. Thus, often when there is a big collaborative announcement, the lab heads and lead investigators (read: post-docs or graduate students) all get to bask in the glory. Note that I am not confusing lead investigator with principle investigator (the person who has ultimate responsibility for the project, and is nominally the laboratory head), as you seem to be.

Actually, the topic was about observations that imply the existence of a process that *could* be explained by the presence of liquid water (brine, actually) flowing across the surface of Mars. The existence or non-existence of life never came up in the press conference, though Dr. Pratt was at pains to point out that we now have more observational evidence that a key element of life as we know it is present on the surface of Mars. In science one can't confirm an hypothesis; one can only fail to refute it. Your crass "or it may mean fucking nothing" part is always implied, and doesn't really need to be asserted; scientists and other rational people know they live in a doubt-filled world. If this uncertainty bothers you, I suggest you stay away from science and stick to the comforting guarantees of religion, where you don't have to be troubled by rational processes like doubt...

[elrous0]

Your crass "or it may mean fucking nothing" part is always implied, and doesn't really need to be asserted

Actually, it does--because these press conferences are presumably aimed at non-scientists. Not that NASA would ever do that, of course. They're perfectly happy to have the press misconstrue their claims, as it ultimately benefits them politically.

If this uncertainty bothers you, I suggest you stay away from science and stick to the comforting guarantees of religion, where you don't have to be troubled by rational processes like doubt...

This has nothing to do with science. It's about NASA PR. If it was just about science, NASA would publish a paper, not hold a press conference announcing a mere hypothesis.

Jobtanium

Some are claiming that Congress is under the sway of a weird new kind of distortion field while others are claiming that Congress itself is a distortion field.

In totally unrelated news, a company in Redmond, Washington has just announced they intend to manufacture a Jobtanium mine here on earth. A large, sweaty monkey has been seen chanting "I'm going to f---ing kill Jobs." President Obama has released a statement declaring that anyone killing jobs will be considered a Republican. Republican leaders responded with the retort, "Jobtanium is new kind of tax and we're naturally against that".

President Assad of Syria declared he was for a multi-party system and Col. Q's son declared an alliance with Islamic terrorists. Dogs and cats have been seen moving in together. A twinkie the size of Manhattan composed of psycho-kinetic energy has also been spotted, but not by reliable witnesses.

I would assume everyone on slashdot knows that GMT has been replaced by UTC.

They're nearly the same thing. There's two things that everyone should know about GMT and UTC:

• * UTC is more specific than GMT. This makes it a better standard
• * UTC and GMT never differ by more than a second

So, UTC is better for system administration, because the standard is more exact. If you are giving a time for a press conference, and the margin of error is more than a second anyway, GMT is perfectly fine. Many people would say GMT is preferable in such situations, because the "G" is recognizable as Greenwich, and that translates to a real place.

tl;dr: UTC is for computers. GMT is for humans.

Nah, just realistic. The discovery of an alien spacecraft would have major national security implications.

As I said elsewhere, a discovery of an alien spacecraft would have major national security implications.

[jmorris42]

> If you think the government is competent enough to pull off any kind of serious

Yea, that is my problem with conspiracy theories. The military can't stop the New York TImes from printing classified material on a regular basis. War secrets from a war that is still hot, that almost certainly get soldiers KIAed. Neither can the State Dept. keep it's secret cables secret from the nefarious NYT. The White House and the Congress leak like sieves to everyone. But the government has kept that dead alien and the ship he rode in on hidden away in Area 51 for decades. The Truthers all believe that President Bush was a retard and at the same time pulled off the most insanely bold black op in history and has managed to keep it a total secret... well except from the smart people who see right through it to the "Truth." Yea, the Truth is out there. Way out there.

Even though the government did keep the Manhattan Project off the pages of the NYT (only because they weren't OPENLY treasonous back then, it would have been both bad for business and life expectancy) it is now well known that the Soviets were deeply infiltrated and thus following progress in almost real time. I wouldn't bet much that the Germans weren't also aware of at least the existence of it and of the general progress. And while they weren't printing anything, anyone want to bet somebody at the Times didn't know about it?

And yes the NYT is treasonous. A moonbat could have at least argued the published leaks before Jan '09 were some misguided effort to thwart the Evil Bush the fact they continued with the practice after their preferred candidate won shows they are not simply misguided patriots but on the other f*cking side. Sorry, when you lend aid and comfort to an enemy during time of hostilities you are a traitor. Period. It is a sign of the loss of confidence in our own civilization that we don't have the moral clarity to put Pinch up against a wall. (After a fair trial of course.... exhibit A, a copy of the NYT, the prosecution rests. Verdict GUILTY. Sentence: Death. total time 1 hour.)

Re:What Could it Be?

[Penguinisto]

If you think the government is competent enough to pull off any kind of serious conspiracy, you've obviously never worked with any government organization ...

Yes and no. Let me explain...

The F-117 Stealth Fighter program was only hinted at here and there as early as 1985-86. Project Senior Trend was only officially admitted to in 1987-88, with very few details and a gawdawful fuzzy image. The original research project, Have Blue, never surfaced until after Desert Storm. The first time the public saw the things in any real detail was in 1990. The program itself OTOH began in the early 1970's, and the first aircraft flew in 1981.

We're talking at least 12 years before the thing was considered anything more than an easily-dismissed conspiracy theory, and at least 7 years of operational activity.

I'd say that if the government was dead serious about a project, they could certainly pull it off. All they'd really ahve to do is fold it into some distractive left-right issue and the public would happily not know for a very long time.

Re:What Could it Be?

[c6gunner]

We're talking at least 12 years before the thing was considered anything more than an easily-dismissed conspiracy theory, and at least 7 years of operational activity.

Well, no. It became operational in 1983 and was "revealed" to the world in 1988 - that's more like 5 years of operational activity before everyone knew about it. There were certainly hints about it's existence prior to that, though, and there's little doubt in my mind that foreign governments knew about it well before the general public did.

More importantly, though, there's a WEEEE bit of a difference between "let's make a plane and not tell anyone" and "let's murder NASA scientists and then create a secret program to recover an alien space ship from Mars". The former is doable, if quite difficult - the latter is impossible.

I'd say that if the government was dead serious about a project, they could certainly pull it off. All they'd really ahve to do is fold it into some distractive left-right issue and the public would happily not know for a very long time.

Heh. I can just see it now. Obama standing behind his podium, saying "Yeah, it's true, we executed a bunch of scientists. But they were Republican scientists, dammit!".

Not sure how you'd wrap something like that into a left-right issue :p Anyway, while it may be easy to fool the public, it's much harder to fool your political opponents, or foreign governments.

Methane, Large sources of easily available water, or Oil. One of those three are the most likely.

Considering the focus on geology, it's also possible they've found a surface deposit of some rare earths minerals (such as those which are currently exported only by China), though you're right, methane is probably the most likely, and while geologists studying Mars might find it interesting, it's not nearly as significant to the rest of the human race.

Focus on geology? What else would you expect study of a planet to be focused on? That's what geology is.

Oil? Obviously you must be joking.

Oh, and rare earths aren't; rare earth ores are somewhat more so, but that is more a function of economics than anything else (an ore is an economically recoverable mineral resource; there are ample rare earth mineral resources around Earth, just not generally economic to recover - but that depends entirely on the price). No amount of rare earths on Mars are going to mean anything to anybody in economic terms until long after people are living there, if ever.

That would move people off their asses off to the nearest start, certainly to Mars as well.

Guessing no longer necessary -- paper here

[Anonymous Coward]

Here's the paper, just published in Science (unfortunately not open access). They're interpreting dark, downward-branching linear features that seasonally form on steep slopes as seasonal flows of water on the surface -- essentially seasonal surface springs of what what would have to be fairly briny water. They incrementally form in the warm season (i.e. progressively extend down the slope) and disappear in the cold season.

Some people were guessing earlier that it might have to do with methane. Apparently not. This is an extension of previous work on Martian gullies from Mars Global Surveyor and other imagery.
