The Curiosity rover had sent more remarkable images
from Mars’ surface, including the first 360-degree view of its
surroundings, NASA’s Jet Propulsion Laboratory (JPL) in Pasadena,
California, which operates Curiosity, has said.
The
images from Curiosity’s just-activated navigation cameras, or Navcams,
after the mast has been lifted, include the rover’s first self-portrait,
looking down at its deck from above. Another Navcam image set, in
lower-resolution thumbnails, is the first 360-degree view of Curiosity’s
new home in Gale Crater.
Also, two higher-resolution Navcams have provided the most detailed depiction to date of Mars surface adjacent to the rover.
“These
Navcam images indicate that our powered descent stage did more than
give us a great ride, it gave our science team an amazing freebie,” said
John Grotzinger, project scientist for the mission from the California
Institute of Technology in Pasadena.
“The thrust
from the rockets actually dug a one-and-a-half-foot-long trench in the
surface. It appears we can see Martian bedrock on the bottom. Its depth
below the surface is valuable data we can use going forward,” Mr.
Grotzinger added.
Jennifer Trosper, JPL project
systems manager, said the rover has deployed its seven—foot mast, which
holds cameras and science and communications instruments. She said the
rover has established full communications with Earth and has more power
output than expected.
“The rover works perfectly,” she said.
Like Mojave
Curiosity
project scientist John Grotzinger compared one of the new images sent
from Mars to the Mojave Desert at a press briefing Wednesday.
“It’ s quite an experience to be looking at a place that feels really
comfortable” and familiar, he said. “What’ s going to be interesting is
finding out all the ways that it’ s different.” Scientists know that the
crater where Curiosity is situated was covered with water in the past,
and the rover itself may well be sitting on the edge of what was once a
river delta. Three-mile high Mount Sharp also sits in the midst of the
100 miles in diameter crater, and will be a major focus of the mission,
according to JPL.
High-resolution close-up images
released Wednesday also show what appear to be pebbles and gravel over a
layer of what scientist believe is bedrock. One set of images also
shows a small nearby indentation with exposed rock.
“You can see a harder, rocky surface under gravel and pebbles,” Mr.
Grotzinger said, indicating that the site could become the rover’ s
first destination.
