now the latest from mars, where a nasa rover called curiosity continues to roll across the martial landscape. it is still sending back stunning photos as it searches for signs of life. the biggest discovery? they have all the building blocks for life. >> reporter: from marches, curiosity can barely sigh earth, more than 30 million miles away, but curiosity is seeing mars as never before, leaving its mark, its tracks and sending back postcards of sand dunes, 20 feet tall, extending for miles. ancient stone lake bids that have been dry for billions of years. and time lapse pictures of a marti martian sunset. curiosity poses for selfies along the way as shy works to

solve mars' most challenging mysteries. >> so we're reading the rocks with curiosity. >> reporter: raiding the rocks. this geologist helps decide what pictures curiosity should take and where it should go. hundreds of scientists and engineers support the rover. they can't drive it in real time from earth because there's a 30-minute time lag to get a message to mars and back. so curiosity shown in this nasa animation gets its instructions biemed up at the start of each day, and the rover is such a talented jieologist that it can teach us a lot from a single pebble fused into a bigger rock. >> there's a pebble right here, and it's actually quite round. >> reporter: and on mars, round pebbles mean they used to be wet. >> if you think about pebbles that you find in a stream on earth, they tend to be very

round as well. as they move in the stream, pebbles are hitting other pebbles, and they round off all the other corners. and that shows us they were formed in rushing water. this is the first evidence we have from the surface that water flowed across the surface of mars. >> reporter: this nasa animation is based on mars' actual surface. curiosity's capabilities include a laser that zaps rocks up to 25 feet away to find out what they're made of. it's the first rover that can drill for samples of mars and analyze them in its built-in lab. an early sample told us more about that water that used to be here and led to curiosity's biggest find so far. >> water on the surface of mars, you could scoop it up and drink it. >> reporter: rob manning, chief engineer told us that because the water was drinkable and because curiosity also found essential organic chemicals,

mars could have supported life. >> does that mean life was there? it doesn't. we don't know. >> reporter: you're talking about my kroibial life. >> microbial, single-cell organisms, but if you would look for on the surface you wouldn't find. you'd have to go underground, just like in this planet you have millions of life underground. >> reporter: life may have traveled back and forth between mars and earth. >> when a meet orcomes along and hits mars, a rock from mars can be lifted up, travel then, encircles around the sun until some day it will bump into earth and land in say antarctica. >> reporter: where a rock from mars was discovered in 1984. >> right. we found mars rocks, and we found them all over earth. and the reverse is also true. certainly earth rock with life in it has taken a trip to mars. >> reporter: could that life survive the trip?

>> we believe -- >> reporter: 30 million miles. >> we don't now. we think life might be able to do that. >> reporter: get ready. here's the punch line. >> could have been that mars was haktable before earth was and life got its foot holiday on mars. and took its journey to earth and we're all martians. >> reporter: do you know how mind employing that was? >> mars could have been habitable when earth wasn't. we're looking at rocks that are very, very old. >> reporter: how old? >> billions and billions of years. moist of earth is constantly recycling as the plates move around. but here on mars we don't have evidence for plate tectonics. this is the mars rock history. and that's a unique opportunity to explore a time in the solar

system that may not be preserved on the surface of earth. >> reporter: the scare yis part was curiosity's landing on mars. it couldn't bounce cushioned by air bags. it weighs a ton, too big for the bags. so the lead engineer and his team came up with the bizarre plan to pack curiosity into a flying saucer. fie fire rockets to slow its descent and use long cables to lower it onto mars. many here thought they were crazy. >> the team recognized that if we failed we would find no comfort or solace from the jech general public. >> reporter: there would be a lot of fingers pointed. >> the man on the streit could have said, that looks crazy. so i would develop this statement, it goes like this. great works and great folly may

be indistinguishable at the outset. >> reporter: because of the communication time lag, they could not direct the landing from earth. the complex maneuvers were preprogrammed, he and his team could only wait and worry. >> we were just sitting in the control room -- >> reporter: biting your fingernails. >> pacing back and forth trying to remember to breathe. >> reporter: here's animation of the landing. and the actual reaction at mission control. [cheers a [cheers and applause] >> the team celebrated. and then sometime in the wee hours of the morning, i went home, crawled into bed with my wife and wept, because i was spent. i was overwhelmed. >> reporter: you can see the full report on our website, cbsness.com. the overnight news will be right back. ,,,,,,,,,,,,,,,,

traditional model of a mouse in a lab. >> the mouse doesn't have the same history as we do. dogs get exposed to many dive ain't generals. >> reporter: get exposed to a lot more. >> on the left is a human leg bone. >> reporter: and osteosarcoma in kids and dogs is astonishingly similar. >> this is the dog here, and it looks almost exactly the same. >> reporter: it sure does. >> and the ultimate goal here? >> very promising new drugs for osteosarcoma. >> reporter: with any drug, a new drug might even come in zoe's lifetime. if not, well, it will still have her paw prints all over it. so you just want to help, right, zoe. for some of you check back a little later for cbs this morning. from the broadcast center in new york city, i'm jeff glor.
