Pictures of Spacecraft
The rover achieves communications through three antennas. The cylinder-shaped ultra-high frequency (UHF) antenna is for communications with orbiting spacecraft. The pole-shaped low-gain antenna (LGA) and hexagonal, steerable high-gain antenna (HGA) are for direct-to-Earth (DTE) communications. These images were taken on sol 125 (December 12, 2012), when the rover was in Yellowknife Bay.
From the Roscosmos website, a photo album of the Phobos-Grunt sample return mission spacecraft being removed from its crate and tipped upright in preparation for final integration onto its launch vehicle. The photos were posted here on October 18, 2011.
As Curiosity approached Dingo Gap, it was taking images of the wheels following every drive in order to monitor wheel degradation. Here, the wheels have picked up sand from the sand drift across Dingo Gap.
As Phoenix descended, HiRISE captured a photo of the lander, its parachute, and the blackened heatshield that slowed Phoenix' entry into Mars' atmosphere, recently detached and falling ahead of the spacecraft.
When the HiRISE camera captured the image of Phoenix descending under its parachute, it also captured some color data, though unfortunately not on top of Phoenix. The gaps between the color strips are caused by the fact that the camera's detector is actually made up of 14 staggered CCDs, and the spacecraft had to slew at an angle in order not to capture a distorted view of Phoenix. Most of the color information indicates that the landscape is the usual red of Mars, but some blue spots indicate the presence of frost inside Heimdall crater.
This image was taken during the REMS integration into the rover, and shows two of the wind sensor boards. Each boom has three identical boards (Boards 1 and 3 on the sides, and 2 on the lower part of th boom). Board 1 and 3 are connected to Board 2 by a flexible circuit and this is connected to the integrated circuit board, in the back of the boom, by another flexible circuit. Each board has four hot dice and one cold die (the four hot dice are in the front of the board and the cold one is in the back). All dice are identical, manufactured in silicon, with three resistors printed on the upper side and thermally isolated from the board by four pillars with a low thermal conductance. In the hot dice, a resistor is used to heat it, another one is used as a sensor to measure the temperature, and the third one is used as reference sensor in the measurement circuit. In the cold die, the only resistor used is the reference resistor. The control loop compares the temperature of the hot dice with that of the cold die, to control the power injected to keep a constant predefined temperature difference (delta temperature) between them. Each board has an additional thermistor on its inside face to monitor the board’s temperature and evaluate the conductive thermal losses of the dice.
On sol 526 (January 28, 2014) Curiosity used its MAHLI camera to investigate one of the two wind-sensor booms sprouting out of the rover mast, part of the Rover Environmental Monitoring Station (REMS) instrument suite. The wind sensors on Boom 1 have not worked properly since landing, although they checked out fine during cruise.
On sol 513 (January 15, 2014), Curiosity performed a series of short drives followed by MAHLI imaging of each of the wheels, to survey their condition. Here, the images have been sorted and the inter-cleat spaces numbered to make it easier to survey the locations of specific marks, tears, and punctures.
This panoramic view around the Chang'e 3 lander was captured on December 20, 2013. This version has been cleaned of vignetting and other artifacts to make a more seamless-looking panorama.
This version of the Mars Pathfinder "Presidential Panorama" has been composited with many images captured of Sojourner throughout the mission. This provides a visual scale for understanding the sizes and distances of rocks surrounding the lander as well as a record of the travels of the rover. Several of the rover images were captured in full color. The rest were colorized using color sampled from those frames.
This is an artist's concept of the slow lunar sunrise on the Chang'e 3 rover. The faint inclined glow in the sky is the Zodiacal light, made of sunlit fine particles forming a flattened lens-shaped mass along the plane of the planets' orbits.
Chang'e 3 captured the images for this panoramic view around the landing site on December 17 and 18, 2013. The images have been mosaicked into a polar azimuthal projection, showing the full 360 degrees of terrain around the lander.
