NASA launches new spacecraft to Mars

NEW: MAVEN logs more than 14,000 miles on its first day, NASA says
The unmanned probe is en route to Mars to study the red planet's atmosphere
The mission launched Monday afternoon; it's scheduled to arrive in September 2014







(CNN) -- You may have heard it before: Billions of years ago, Mars probably looked more like Earth does now, with clouds and oceans and a much thicker atmosphere. It may even have had some type of microbes. But now it's a barren, frozen desert.
So what happened? Wre did the air and water go?
That's what the spacecraft NASA launched Monday is being dispatched to find out. It's called MAVEN -- short for Mars Atmosphere and Volatile Evolution -- and it's the first mission dedicated to studying the red planet's upper atmosphere.

Is this ancient Mars? An artist shows how Mars might have looked billions of years ago. A new NASA spacecraft, called MAVEN, will be the first mission devoted to exploring and understanding the Martian upper atmosphere. Scientists hope it will solve the mystery of the red planet's missing air and water.

MAVEN, short for Mars Atmosphere and Volatile Evolution, will help scientists figure out what happened to the red planet's atmosphere. This artist's concept shows what the spacecraft will look like when it reaches Mars. The spacecraft will orbit the planet in an elliptical orbit that allows it to pass through and sample the entire upper atmosphere on every orbit. The spacecraft will investigate how the loss of Mars' atmosphere to space determined the history of water on the surface.

Martian dust appears on the surface of a penny, brought along with NASA's Curiosity rover and photographed by the Mars Hand Lens Imager on October 2. The image of the 1909 coin is at the highest resolution possible for the high-powered camera -- 14 micrometers per pixel (a micrometer is about .000039 inches). The rover touched down on Mars in August 2012 with a mission to explore the Gale Crater, once thought to have hosted flowing water, and to find out if that environment was ever habitable.
cnnArticleGallery.currentImageList[cnnArticleGallery.currentImageList.length] = {"currentPicture":true,"x":4,"y":2,"pos":1,"title":"Mars rover Curiosity"}





The Curiosity rover took this image on September 10 of a rock formation informally dubbed "Darwin," first noted from the orbiting spacecraft. Scientists had the rover stop in this region, called Waypoint 1, because it appears to be a prime area to study the inner makeup and history of the floor of the Gale Crater. Analysis of Darwin may provide evidence of whether and how water played a role in the layering of rocks in this region.

The 2,000-pound rover Curiosity landed on Mars on August 6, 2012, and has been sending back fascinating images and data ever since. Curiosity recently began a trek toward Mount Sharp after spending more than six months in the "Glenelg" area. This image was taken on July 16, after the rover passed the 1 kilometer mark for the total distance covered since the start of the mission. It still has over 8 kilometers (5 miles) to cover before reaching Mount Sharp, which will take several months.
cnnArticleGallery.currentImageList[cnnArticleGallery.currentImageList.length] = {"currentPicture":false,"x":4,"y":2,"pos":3,"title":"Mars rover Curiosity"}





The lower slopes of Mount Sharp are visible at the top of this image, taken on Tuesday, July 9. The turret of tools at the end of the rover's arm, including the rock sampling drill in the lower left corner, can also be seen.

Mars once had conditions favorable for microbial life, NASA scientists announced Tuesday, March 12, 2013. One piece of evidence for that conclusion comes from this area of the Martian surface, nicknamed "Sheepbed." It shows veins of sediments that scientist believe were deposited under water and was an environment once hospitable to life.
cnnArticleGallery.currentImageList[cnnArticleGallery.currentImageList.length] = {"currentPicture":false,"x":4,"y":2,"pos":7,"title":"Mars rover Curiosity"}





The rock on the left, called Wopmay, was discovered by the rover Opportunity, which arrived in 2004 on a different part of Mars. Iron-bearing sulfates indicate that this rock was once in acidic waters. On the right are rocks from Yellowknife Bay, where rover Curiosity is situated. These newly discovered rocks are suggestive of water with a neutral pH, which is hospitable to life formation.

NASA's Curiosity rover found evidence for what scientists believe was an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here. The key evidence for the ancient stream comes from the size and rounded shape of the gravel in and around the bedrock, according to the Jet Propulsion Laboratory/Caltech science team. The rounded shape leads the science team to conclude they were transported by a vigorous flow of water. The grains are too large to have been moved by wind.
cnnArticleGallery.currentImageList[cnnArticleGallery.currentImageList.length] = {"currentPicture":false,"x":4,"y":2,"pos":28,"title":"Mars rover Curiosity"}





This photos shows an up-close look at an outcrop that also shows evidence of flowing water, according to the JPL/Caltech science team. The outcrop's characteristics are consistent with rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of conglomerate rock of this size.

"We expect to learn how the modern Mars works, really in detail. To see its climate state, to understand how the atmosphere is lost to space -- how Mars may have lost a magnetic field -- to take that information and map it back in time," said NASA's James Garvin.
MAVEN lifted off shortly before 1:30 p.m. ET from Cape Canaveral Air Force Station in Florida, starting a 10-month trip. By late afternoon, it was more than 14,000 miles from Earth en route to a September 22, 2014 rendezvous with Mars.
The solar-powered probe is about the length of school bus -- 37.5 feet (11.43 meters) -- and will weigh about 5,410 pounds (2,454 kilograms) at launch.
What killed Mars? New spacecraft will find out
"MAVEN will fill in a very big gap in our understanding of the planet by exploring the upper atmosphere and its influence on the Martian environment," principal investigator Bruce Jakosky, from the University of Colorado, says on his NASA webpage.
He says he's "excited that we're providing one step along the path of answering questions about whether life ever existed on Mars."
Jakosky's team will use the spacecraft's three instrument suites in hopes of determining three things about Mars:
• The composition of its upper atmosphere
• How fast it's losing what's left of its atmosphere
• The history of the atmosphere
MAVEN won't make a cool, daring landing like the Mars Curiosity Rover, which has been roaming Mars for more than a year now. Instead, it will orbit between a low of about 93 miles (150 kilometers) above the surface to a high of about 3,728 miles (6,000 kilometers). It also will make five dives, flying as low as 77 miles (125 kilometers) in altitude.
NASA says the mission will cost $671 million.
