Curiosity Rover’s Self Portrait at ‘John Klein’ Drilling Site, Cropped

This rectangular version of a self-portrait of NASA’s Mars rover Curiosity combines dozens of exposures taken by the rover’s Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity’s work on Mars (Feb. 3, 2013).

The rover is positioned at a patch of flat outcrop called « John Klein, » which was selected as the site for the first rock-drilling activities by Curiosity. The self-portrait was acquired to document the drilling site.

The rover’s robotic arm is not visible in the mosaic. MAHLI, which took the component images for this mosaic, is mounted on a turret at the end of the arm. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images. The arm was positioned out of the shot in the images or portions of images used in the mosaic.

Malin Space Science Systems, San Diego, developed, built and operates MAHLI. NASA’s Jet Propulsion Laboratory, Pasadena, Calif., manages the Mars Science Laboratory Project and the mission’s Curiosity rover for NASA’s Science Mission Directorate in Washington. The rover was designed and assembled at JPL, a division of the California Institute of Technology in Pasadena.

Mariner 10’s Portrait of Venus

Mariner 10
Mariner 10

Le 5 février 1974, 39 ans jour pour jour, Mariner 10 a pris cette première photo en gros plan de Vénus.

Fabriqué en utilisant un filtre ultraviolet dans son système d’imagerie, la photo a été amélioré par couleur pour faire ressortir atmosphère nuageuse de Vénus que l’œil humain verrait. Vénus est perpétuellement recouvert par un épais voile de nuages ​​élevés de dioxyde de carbone et la température de surface se rapproche de 900 degrés Fahrenheit.

Lancé le 3 novembre 1973 au sommet d’une fusée Atlas-Centaur, Mariner 10 a volé vers Vénus, en 1974.
