Three spectacular new panoramas give an eye-popping look at NASA's Mars rover Curiosity hard at work on the Red Planet.

Each photo is a mosaic stitched together using more than 20 raw images taken by the Curiosity rover itself, said New Jersey-based scientist and journalist Ken Kremer, who created the panoramas along with his imaging partner Marco Di Lorenzo.

The mosaics "show the context for each spot where the rover is toiling away — compared to individual frames that just give a rather narrow view and incomplete experience," Kremer told SPACE.com in an email. "The wide view lets you experience Mars as if you were standing on the Red Planet's surface — and from the human perspective." [Mars Rover Curiosity's Latest Photos]

One of the mosaics shows Curiosity with its huge robotic arm deployed, studying a rocky outcrop called "John Klein" on Jan. 25-26, 2013. About two weeks later, the rover drilled 2.5 inches into a section of John Klein, collecting the first-ever samples from the interior of a Martian rock.

Another mosaic is a self-portrait Curiosity took at John Klein on Feb. 3. The third shows Curiosity on March 23, still at the drill site, with its arm elevated and its drill pointed at the viewer — seemingly flexing its muscles after recovering from a computer glitch that knocked out its main computer system in late February.

The mosaics help paint a picture of Curiosity and its mission, which aims to assess Mars' potential to host past or present microbial life, Kremer said.

"I chose these scenes because they vividly tell the story of what NASA seeks to accomplish with Curiosity in the search for signs of life on Mars as well as tell the science story of the entire mission at a glance — one panorama is worth a thousand words, so to speak," he said.

Curiosity has already accomplished its main mission goal. The rover's analysis of the John Klein drill samples enabled mission scientists to determine that the Red Planet was indeed habitable billions of years ago.

The rover team made this announcement in March, just seven months after Curiosity touched down inside Mars' huge Gale Crater.

Two of the three new photo mosaics prominently feature Mount Sharp, the mysterious 3.4-mile-high mountain that rises from Gale's center. That's no accident, Kremer said.

"Whenever possible with horizon scenery we include Mount Sharp — it's a dramatic backdrop as well as being the rover's ultimate destination," he said.
