Here is a look at some of the stories that CNN plans to follow this week:
Mars rover on the move
The Mars rover Curiosity could go for its first, short test drive this week, roughly two weeks after landing.
The mobile science lab touched down on Mars early on August 6 and has been beaming back images of the surface of Gale Crater ever since. But it hasn't yet moved from its landing site. Controllers needed to execute a planned upgrade of its control software and make sure its systems operate properly.
Curiosity is on a two-year mission to determine whether Mars ever had an environment capable of supporting life.
Holiday travel forecast
AAA will release its forecast for travel over the upcoming Labor Day holiday on Tuesday.
The organization will look at how many people are planning Labor Day trips and what effect the sluggish economy will have on their travel plans. Numbers on road as well as air travel are expected.
Debris discovered in the depths of the South Pacific may be remnants of vanished aviator Amelia Earhart‚Äôs plane.
‚ÄúA review of high-definition underwater video footage taken during the recently-completed Niku VII expedition has revealed a scattering of man-made objects on the reef slope off the west end of Nikumaroro,‚ÄĚ The International Group for Historic Aircraft Recovery reported on its website.
The question researchers are now asking: Do these new images reveal parts of the same plane captured in a 1937 photo of Nikumaroro.
Discovery News reports that the 1937 photo of the island's western shoreline was taken three months after Earhart and¬†her navigator, Fred Noonan,¬†disappeared. The shot by British Colonial Service officer Eric R. Bevington, ‚Äúrevealed an apparent man-made protruding object on the left side of the frame.‚ÄĚ Forensic analysis of the image ‚Äúfound the mysterious object consistent with the shape and dimension of the upside-down landing gear of Earhart's plane.‚ÄĚ
"The Bevington photo shows what appears to be four components of the plane: a strut, a wheel, a wom gear and a fender. In the debris field there appears to be the fender, possibly the wheel and possibly some portions of the strut," TIGHAR forensic imaging specialist Jeff Glickman told Discovery News.
TIGHAR launched the expedition last month, working on a theory that Earhart and Noonan became stranded and ultimately met their deaths on Nikumaroro Island after their Lockheed Electra plane was swept out to sea 75 years ago.
The group‚Äôs ninth expedition to the island kicked off with a chorus of excitement and criticism around the Internet. Researchers ultimately returned to the U.S. admitting they had found no obvious signs of the plane.
But new analysis of an underwater debris field may prove the researchers found exactly what they were looking for.
"Early media reports rushed to judgment in saying that the expedition didn't find anything," Ric Gillespie, TIGHAR executive director, told Discovery News. "We had, of course, hoped to see large pieces of aircraft wreckage but as soon as we saw the severe underwater environment at Nikumaroro we knew that we would be looking for debris from an airplane that had been torn to pieces 75 years ago."
Glickman told Discovery News the group has reviewed less than 30% of the high-definition underwater video taken on the recent expedition, which launched July 12 and concluded on July 24.
TIGHAR theorizes that Earhart and Noonan landed on Nikumaroro Island – then called Gardner‚Äôs Island – after failing to find a different South Pacific island where they were planning to land. The pair is believed to have landed safely and called for help using the Electra‚Äôs radio. And in a twist of fate, the plane was apparently swept out to sea, washing away Earhart and Noonan‚Äôs only source of communication. U.S. Navy search planes flew over the island, but not seeing the Electra, passed it by and continued the search elsewhere.
"What makes this the best expedition is the technology we've been able to assemble to search for the wreckage of that airplane," Gillespie told CNN last month. "We have an autonomous vehicle. We have multibeam sonar above the University of Hawaii ship we're on right now. We have a remote-operated vehicle to check out the targets (and a) high-definition camera. We're all set."
Gillespie told Discovery News that if further analysis of the Bevington photo continues to support TIGHAR's theory, the group will seek to recover the objects from the ocean‚Äôs depths.
