Rover Curiosity: More photos, more data from Mars [Google+ Hangout]

August 7, 2012 |  2:48 pm

It was another day of positive news from Mars as officials offered new updates on rover Curiosity.

In a Google+ Hangout, Times reporters Scott Gold and Amina Khan talked about dramatic new photos from Curiosity and of the rover headed to Mars. They said the data coming back from Curiosity has been very positive but that a full schedule of its activities -- including when it might start rolling -- have not been announced.

NASA released Curiosity's first color image from the Red Planet. The photograph, the first of the Martian surface to be taken by the rover's Mars Hand Lens Imager (MAHLI), shows the north wall and rim of Gale Crater in the distance.
Also Tuesday, officials showed reporters a photo snapped by the Mars Reconnaissance Orbiter taken around 10:30 p.m. PDT Monday night. It shows Curiosity on the Martian surface, as well as the rover's discarded heat shield, parachute, back shell and sky crane.

The spacecraft is also expected to pave the way for important leaps in deep-space exploration, including bringing Martian rock or soil back to Earth for detailed analysis and, eventually, human exploration.

INTERACTIVE: Curiosity, from liftoff to landing

Curiosity's landing, it turned out, was as close to perfect as an eight-month journey through space can produce. In interviews with The Times, engineers said initial reviews of Curiosity's final minutes in flight revealed a startling fact: the landing ran into fewer problems than any of the hundreds of simulations they had run over the last two years.

"It was cleaner than any of our tests," said Al Chen, a Jet Propulsion Laboratory engineer and a member of the mission's landing team, shaking his head with amazement. "It was a blast."

"We landed pretty much on this table right here," said Curiosity mission systems manager Michael Watkins, patting his palm on a table at the Jet Propulsion Laboratory. "It's a pretty good spot."

The landing Sunday night brought cheers that continued to echo Monday.

Adam Steltzner, the lead mechanical engineer for entry, spent nearly a decade at JPL working on Curiosity. In a Times Google+ chat Monday, he described what it was like to see the rover on Mars.

"We could not even imagine in our wildest dreams it doing as well as it did," he said.

Steltzner spoke about the nervousness and excitement inside the control room at JPL in the final moments before Curiosity landed. He described it as "a lot of focus occasionally broken up by celebration."

Others at JPL were similarly excited.

"So that rocked. Seriously! Woo!" said Richard Cook, deputy project manager for the Mars Science Laboratory, as  he punched upward with both fists, a sign of victory.

Cook reminisced about how far they had come since the 1997 Pathfinder mission, which sent the first rover, Sojourner, to skitter across the Martian surface. Sojourner was a relatively simple, skateboard-sized affair, whereas the latest rover — known as Curiosity — is a laser-zapping, video-shooting chemical laboratory on wheels.

"Pathfinder was great, but we were young and stupid, frankly," Cook said, to much laughter.

The elation was mixed with relief.

“I’m so glad we nailed that sucker!” mission systems engineer Randii Wessen said.

The real goal of the mission — a  hunt for the building blocks of life and signs that Earth's creatures may not be alone in the universe — is just beginning.
