ZZ-ZZ-ZZ-ZZ-ZZ-ZZ-CTX_Moon_6Oct2004.jpgThe Moon from Mars Reconnaissance Orbiter138 visiteThis image of Earth's moon was acquired by the Mars Reconnaissance Orbiter (MRO) Context Imager (CTX) camera during calibration and testing between 2:00 and 3:00 a.m. Pacific Daylight Time (PDT) on 6 October 2004. The image was taken by CTX before it was delivered and mounted on the MRO spacecraft. It was obtained from the parking lot at the Malin Space Science Systems facility in San Diego, California. In this image, east is toward the top and south is toward the bottom. The image demonstrates the field of view of the MRO CTX camera, which is 5064 pixels across (clicking on the image above will permit download of the full 5064 pixels-wide image). When in its circular mapping orbit about Mars, the 5064 pixels will cover a swath that is about 30 kilometers (~18.6 miles) across. CTX will obtain its 30 km-wide images at a resolution of about 6 meters (~19.7 feet) per pixel. CTX images will be used to provide context for the very high resolution images (better than 1 meter per pixel) to be obtained by the MRO HiRISE camera. CTX data will also provide context for MRO's CRISM infrared imaging spectrometer as well as provide detailed observations of martian landforms and potential, future Mars landing sites.

Zhurong-0006-d41586-021-01588-6_19249954.jpgZhurong from MRO100 visiteAll three missions launched around the same time due to an alignment between Earth and Mars on the same side of the sun, making for a more efficient journey to the red planet.
Zhurong landed in a large plain in Mars' northern hemisphere called Utopia Planitia. It's where NASA's Viking 2 lander touched down in 1976.
China's ambitious space program triggered headlines earlier this month when an out-of-control rocket, weighing nearly 40,000 pounds, plunged into the Indian Ocean -- triggering a rebuke from NASA for failing to "meet responsibility standards regarding (its) space debris."
The Long March 5B rocket had launched part of China's new space station into orbit in late April and had been left to hurtle through space uncontrolled until Earth's gravity pulled it back in.
On Saturday, China's President Xi Jinping sent his congratulations on the successful Mars mission, hailing it as an "important step in China's interstellar exploration."
Though Chinese authorities and state media have hailed Tianwen-1 as the country's first mission to Mars, that isn't quite true.
China's first attempt to reach Mars was in 2011 with the Yinghuo-1 probe, which was supposed to orbit the red planet and study its environmental structure. It launched from Kazakhstan in tandem with the Russian Phobos-Grunt mission in November that year, which was supposed to orbit the red planet and study its environmental structure.
But the mission failed, with a malfunction that stranded the probe in Earth orbit's shortly after launch. In 2012, the spacecraft reentered the Earth's atmosphere and fell back to Earth, landing in the Pacific Ocean.MareKromium
