Mars 'more active than suspected' [MARS GLOBAL WARMING]

Mars 'more active than suspected'

Gullies have appeared in new images taken this year New images of Mars suggest the Red Planet's surface is more active than previously thought, the US space agency (Nasa) reports. Photographs from Nasa's orbiting spacecraft Mars Global Surveyor show recently formed craters and gullies.

The agency's scientists also say that deposits of frozen carbon dioxide near the planet's south pole have shrunk for three summers in a row.

They say this is evidence to suggest climate change is in progress.

Mars rumble

The new gullies appear in an April 2005 image of a sand-dune slope. A previous shot from July 2002 had no trace of them.

The team operating the Mars Orbiter Camera on MGS has found many sites on the Red Planet with fresh-looking gullies, and checked back at more than 100 gullied sites for possible changes between imaging dates, but this is the first such find.

Such gullies might have formed when frozen carbon dioxide, trapped by windblown sand during winter, vaporised rapidly in spring, releasing gas that made the sand flow as a gully-carving fluid, the team speculate.

"To see new gullies and other changes in Mars' surface features on a time span of a few years presents us with a more active, dynamic planet than many suspected," said Nasa's Michael Meyer, Nasa's Mars Exploration Program chief scientist.

Bright future

The newly released images also show boulder tracks at another site, which were not there two years ago.

Michael Malin, the principal investigator on the Mars Orbiter Camera, said it was possible strong winds or even some kind of seismic activity had caused them to roll to their new positions.

But some changes may be happening slower than expected, the scientists report.

Studies suggested new impact craters might appear at only about one-fifth the pace assumed previously, Dr Malin said. This had important implications, he added, because crater counts were used to estimate the ages of Martian surfaces.

The Mars Global Surveyor has been orbiting the planet since 1997; Nasa expects it to carry on doing so for several years to come.

"Our prime mission ended in early 2001, but many of the most important findings have come since then, and even bigger ones might lie ahead," said Tom Thorpe, project manager for Mars Global Surveyor.

NOTE the key paragraphs:

THE BBC -- one of the key cheerleaders for global warming hysteria -- has actual knowledge that global warming is occurring on MARS as well as Earth, and the most obvious explanation is THE SUN. We can now see how deeply dishonest and deceitful the BBC really is.

This is a great scientific clue for the warming wackos....

If they even care to accept it.

From a GW moonbat: but mars doesn't have the same magnetic field as Earth!

William of Ockham would say his model predicts what it was programmed to predict.

It's Bush's fault. Just like the Sun's increase in activity is Bush's fault. It all relates to his not signing the Kyoto accords and the Peak Oil theory.

Global Warming Grammer School


Ok , Class sez teacher Steve Lets prove how global warming is going to flood us out.

Step 1. Take a large drinking glass and fill it with ice cubes to represent the ice bergs
Step 2. fill the glass to the top with water (all the way to the top with a water bubble)
Step 3. Increase the air temp in the room
Step 4. Note the time it takes for the frozen water to melt and overflow the glass

Note the results and email them to algore

Fill glass with water and place it outdoors for half an hour. Note: do not do this with the good glassware.

Obviously, the global warming on Earth is more severe than we at first thought, since the extra heat from Earth is radiating towards Mars and melting the polar ice caps.

The Sun has nothing to do with it. /s

Mars warming is being caused by all the mars landers and rovers we earthlings have sent up there. We need to include billions in the federal budget to send clean up crews to Mars to retrieve all our space junk & clean up the environment!

Here in San Diego will not work, but if you fill it ¾ full (mark the spot with tape) and put it in the freezer (grin)

Actually it would not have worked here yesterday and maybe not today either. We got GW bad this week, might even break freezing for the first time since September. Kind of reminds one of a January back in the mid 1970s when it hit 60 one afternoon, very confusing.

Warming on Mars is because of pollution resulting from the operation of the 2 rovers.

They've been there for 3 years. /sarcasm
