Why would this be true?

I'll admit: I've had no physics or chemistry education except what I've learned through reading.

I believe the anouncment yesterday wasn't the mere existence of the water there. We had apparently known that for some time. It's that there is apparently flowing water.


Well duh. You can't have canals without flowing water.

Earth has an active core of churning iron and nickel. This produces an electromagnetic field that protects us from solar winds and such. Maybe some simple life could develop. I don't know. But this puts a pretty big constraint on some greatly advanced civilization developing on Mars.

"Life On Mars?"

It's a god-awful small affair
To the girl with the mousy hair
But her mummy is yelling "No"
And her daddy has told her to go
But her friend is nowhere to be seen
Now she walks
through her sunken dream
To the seat with the clearest view
And she's hooked to the silver screen
But the film is a saddening bore
For she's lived it
ten times or more
She could spit in the eyes of fools
As they ask her to focus on

[CHORUS]
Sailors fighting in the dance hall
Oh man!
Look at those cavemen go
It's the freakiest show
Take a look at the Lawman
Beating up the wrong guy
Oh man! Wonder if he'll ever know
He's in the best selling show
Is there life on Mars?

It's on Amerika's tortured brow
That Mickey Mouse
has grown up a cow
Now the workers
have struck for fame
'Cause Lennon's on sale again
See the mice in their million hordes
From Ibeza to the Norfolk Broads
Rule Britannia is out of bounds
To my mother, my dog, and clowns
But the film is a saddening bore
'Cause I wrote it
ten times or more
It's about to be writ again
As I ask you to focus on

[CHORUS]
Dring-dring-dring......

Going to Mars doesn't improve the lives of humanity. They are welfare scientists. Really don't have to produce anything.

Here's a start for you and your ignorance of the scientific process. There's much more in the link.

quote:

Space exploration has created new markets and new technologies that have spurred our economy and changed our lives in many ways. This year, NASA unveiled two new complementary interactive Web features, NASA City and NASA @ Home, available at www.nasa.gov/city. The new features highlight how space pervades our lives, invisible yet critical to so many aspects of our daily activities and well-being.
Health and Medicine

Light-Emitting Diodes (LEDs)

Light-emitting diodes
Red light-emitting diodes are growing plants in space and healing humans on Earth. The LED technology used in NASA space shuttle plant growth experiments has contributed to the development of medical devices such as award-winning WARP 10, a hand-held, high-intensity, LED unit developed by Quantum Devices Inc. The WARP 10 is intended for the temporary relief of minor muscle and joint pain, arthritis, stiffness, and muscle spasms, and also promotes muscle relaxation and increases local blood circulation. The WARP 10 is being used by the U.S. Department of Defense and U.S. Navy as a noninvasive “soldier self-care” device that aids front-line forces with first aid for minor injuries and pain, thereby improving endurance in combat. The next-generation WARP 75 has been used to relieve pain in bone marrow transplant patients, and will be used to combat the symptoms of bone atrophy, multiple sclerosis, diabetic complications, Parkinson’s disease, and in a variety of ocular applications. (Spinoff 2005, 2008)

Infrared Ear Thermometers
Infrared ear thermometers
Diatek Corporation and NASA developed an aural thermometer, which weighs only 8 ounces and uses infrared astronomy technology to measure the amount of energy emitted by the eardrum, the same way the temperature of stars and planets is measured. This method avoids contact with mucous membranes, virtually eliminating the possibility of cross infection, and permits rapid temperature measurement of newborn, critically-ill, or incapacitated patients. NASA supported the Diatek Corporation, a world leader in electronic thermometry, through the Technology Affiliates Program. (Spinoff 1991)

Artificial Limbs

Artificial limbs
NASA’s continued funding, coupled with its collective innovations in robotics and shock-absorption/comfort materials are inspiring and enabling the private sector to create new and better solutions for animal and human prostheses. Advancements such as Environmental Robots Inc.’s development of artificial muscle systems with robotic sensing and actuation capabilities for use in NASA space robotic and extravehicular activities are being adapted to create more functionally dynamic artificial limbs (Spinoff 2004). Additionally, other private-sector adaptations of NASA’s temper foam technology have brought about custom-moldable materials offering the natural look and feel of flesh, as well as preventing friction between the skin and the prosthesis, and heat/moisture buildup. (Spinoff 2005)

Ventricular Assist Device

Ventricular assist device
Collaboration between NASA, Dr. Michael DeBakey, Dr. George Noon, and MicroMed Technology Inc. resulted in a lifesaving heart pump for patients awaiting heart transplants. The MicroMed DeBakey ventricular assist device (VAD) functions as a “bridge to heart transplant” by pumping blood throughout the body to keep critically ill patients alive until a donor heart is available. Weighing less than 4 ounces and measuring 1 by 3 inches, the pump is approximately one-tenth the size of other currently marketed pulsatile VADs. This makes it less invasive and ideal for smaller adults and children. Because of the pump’s small size, less than 5 percent of the patients implanted developed device-related infections. It can operate up to 8 hours on batteries, giving patients the mobility to do normal, everyday activities. (Spinoff 2002)

Transportation

Anti-Icing Systems

Airplane anti-icing systems
NASA funding under the Small Business Innovation Research (SBIR) program and work with NASA scientists advanced the development of the certification and integration of a thermoelectric deicing system called Thermawing, a DC-powered air conditioner for single-engine aircraft called Thermacool, and high-output alternators to run them both. Thermawing, a reliable anti-icing and deicing system, allows pilots to safely fly through ice encounters and provides pilots of single-engine aircraft the heated wing technology usually reserved for larger, jet-powered craft. Thermacool, an innovative electric air conditioning system, uses a new compressor whose rotary pump design runs off an energy-efficient, brushless DC motor and allows pilots to use the air conditioner before the engine even starts. (Spinoff 2007)

Highway Safety

Grooves in concrete
Safety grooving, the cutting of grooves in concrete to increase traction and prevent injury, was first developed to reduce aircraft accidents on wet runways. Represented by the International Grooving and Grinding Association, the industry expanded into highway and pedestrian applications. The technique originated at Langley Research Center, which assisted in testing the grooving at airports and on highways. Skidding was reduced, stopping distance decreased, and a vehicle’s cornering ability on curves was increased. The process has been extended to animal holding pens, steps, parking lots, and other potentially slippery surfaces. (Spinoff 1985)

Improved Radial Tires

Radial tires
Goodyear Tire and Rubber Company developed a fibrous material, five times stronger than steel, for NASA to use in parachute shrouds to soft-land the Vikings on the Martian surface. The fiber’s chain-like molecular structure gave it incredible strength in proportion to its weight. Recognizing the increased strength and durability of the material, Goodyear expanded the technology and went on to produce a new radial tire with a tread life expected to be 10,000 miles greater than conventional radials. (Spinoff 1976)

Chemical Detection

Chemical detection
NASA contracted with Intelligent Optical Systems (IOS) to develop moisture- and pH-sensitive sensors to warn of potentially dangerous corrosive conditions in aircraft before significant structural damage occurs. This new type of sensor, using a specially manufactured optical fiber whose entire length is chemically sensitive, changes color in response to contact with its target. After completing the work with NASA, IOS was tasked by the U.S. Department of Defense to further develop the sensors for detecting chemical warfare agents and potential threats, such as toxic industrial compounds and nerve agents, for which they proved just as successful. IOS has additionally sold the chemically sensitive fiber optic cables to major automotive and aerospace companies, who are finding a variety of uses for the devices such as aiding experimentation with nontraditional power sources, and as an economical “alarm system” for detecting chemical release in large facilities.

No.

It's why it has such a thin atmosphere. It had a similar one to Earth and solar wind blew it away over time, where Earth's is mostly shielded.

It is narrow minded when people discount the great benefits we've received from space travel - besides, even without the benefits, don't we have an instinct to explore?
