Mars during the 1999 opposition as seen by space telescope Mars at its 2018 opposition, with its atmosphere clouded by a global dust storm that snuffed out the solar-powered Opportunity rover The James Webb Space Telescope captured its first images and spectra of Mars on 5 September 2022. [99]
Several close-up pictures were taken of the object and preliminary interpretations by scientists suggest the object to be "debris from the spacecraft". [67] [68] [69] Nonetheless, further images in the nearby sand have detected other "bright particles" . These newly discovered objects are presently thought to be "native Martian material".
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
It is known that in the past, Mars has had a much more circular orbit. At one point, 1.35 million Earth years ago, Mars had an eccentricity of roughly 0.002, much less than that of Earth today. [188] Mars's cycle of eccentricity is 96,000 Earth years compared to Earth's cycle of 100,000 years. [189]
The rover could take pictures with its different cameras, but only the PanCam camera had the ability to photograph a scene with different color filters. The panorama views are usually built up from PanCam images. By February 3, 2018, Opportunity had returned 224,642 pictures. [63] [64] A selection of panoramas from the mission:
Did you know Mars is named after the Roman god of war?
The first close-up images taken of Mars in 1965 from Mariner 4 show an area about 330 km across by 1200 km from limb to bottom of frame. In 1964, NASA's Jet Propulsion Laboratory made two attempts at reaching Mars. Mariner 3 and Mariner 4 were identical spacecraft designed to carry out the first flybys of Mars. Mariner 3 was launched on ...
