Curiosity Mars rover to try and 'jump' sand dune



http://www.bbc.co.uk/newsround/26036204

The Curiosity Mars rover is going to try and drive over a one-metre-high sand dune on Mars.

The dune is stopping the rover get to a valley which doesn't have many sharp rocks that can damage the robot's wheels.

It's a risky business, NASA scientists lost an earlier rover in sand back in 2009!

This time Curiosity will first only climb halfway up the dune to see how it reacts to the sand.

3. Okay. I have a question.

How did Curiosity do that selfie? The only part of the rover that is not in view is the edge of the wheel. Shouldn't there be an "arm" or something sticking out of the frame?

I'm sure there is something I'm missing - could someone please point it out?

Bemusedly unenlightened here!

6. Hey - I'm serious!



I am a child of the space age and thrill at the idea that we are doing at least some exploration of other worlds . . . I just noticed this and wondered how the picture was taken.

10. It's probably an extension/arm with another camera.

I have no clue, but that would be my guess.

17. you were correct, congrats !

In case that explanation is not enough for you, NASA's post also offers the following:

“MAHLI is mounted on a turret at the end of Curiosity's robotic arm. The arm is not visible in the portrait because the arm was positioned out of the shot in the images or portions of images used in the mosaic. Some images taken during the day show portions of the arm. However, the Martian ground that the arm hides from view in those images is visible in alternative images chosen for the mosaic, taking the arm out of the scene.”

5. See that big boxlike aparatus at the top center of the frame? That's a camera...

It just pointed the camera at the bathroom mirror.

14. Only one possible explanation

Ok a few

1. It's aliens
2. Another rover
3. An arm that attaches to the arm the wheel is attached to.

Crap it was photoshop all along

9. my guess

There's a very small camera lens aimed at a very small curved mirror on Curiosity. AFAIK there's not two vehicles.

eta: OK I was wrong. See here.

11. NASA reveals secrets of Curiosity’s selfies

http://www.theregister.co.uk/2012/12/14/nasa_explains_curioisty_self_portraits/



NASA has published a long and detailed explanation of just how its Curiosity rover managed to take a self-portrait.

The agency has posted a video, which we've popped at the bottom of the story, and lengthy text explanations of the way it assembled the shot below.

NASA says “Curiosity held the rover's Mars Hand Lens Imager (MAHLI) camera in more than 50 positions in one day to generate a single scene combining all the images, creating a high-resolution, full-color portrait of the rover itself.”

Here's the resulting mosaic self-portrait.

15. Thank you!

I knew there was an explanation!



Now I'll just go off in a corner and mutter about not being able to ask a simple question without having a load of snark fired in response . . . and have another cup of coffee to approach being human this morning. mutter grumble . . .

13. Mars Rover Self-Portrait Shoot Uses Arm Choreography

http://www.nasa.gov/mission_pages/msl/news/msl20121211b.html

PASADENA, Calif. - The robotic arm on NASA's Mars rover Curiosity held the rover's Mars Hand Lens Imager (MAHLI) camera in more than 50 positions in one day to generate a single scene combining all the images, creating a high-resolution, full-color portrait of the rover itself.

A larger version of the previously released self-portrait is now available online, along with an animation video showing how it was taken, and a practice self-portrait taken earlier by Curiosity's test-rover double on Earth.

The new version of Curiosity's self-portrait, online at: http://photojournal.jpl.nasa.gov/catalog/PIA16457 , shows more of the surrounding Martian terrain than a version completed last month.

The animation video at: http://www.nasa.gov/multimedia/videogallery/index.html?media_id=156880341 depicts how the rover moved its robotic arm on Oct. 31 to record the component images that would be combined into the self-portrait. The same software that rover planners use when designing the rover's moves was used to generate the animation.
