May 19, 2016 · Bright, frosty polar caps, and clouds above a vivid, rust-colored landscape reveal Mars as a dynamic seasonal planet in this NASA Hubble Space Telescope view taken on May 12, 2016, when Mars was 50 million miles from Earth. The Hubble image reveals details as small as 20 to 30 miles across.

May 2, 1998 · The sharpest view of Mars ever taken from Earth was obtained by the recently refurbished NASA Hubble Space Telescope. This stunning portrait was taken with the HST Wide Field Planetary Camera-2 on March 10, 1997.

Aug 27, 2003 · This sharp, natural-color view of Mars reveals several prominent Martian features, including the largest volcano in the solar system, Olympus Mons; a system of canyons called Valles Marineris; an immense dark marking called Solis Lacus; and the southern polar ice cap.

Jul 5, 2001 · The Earth-orbiting Hubble telescope snapped this picture on June 26, when Mars was approximately 43 million miles (68 million km) from Earth - its closest approach to our planet since 1988. Hubble can see details as small as 10 miles (16 km) across.

Mar 23, 2008 · NASA’s Hubble Space Telescope took this close-up of the red planet Mars when it was just 34,648,840 miles (55,760,220 km) away. This color image was assembled from a series of exposures taken between 6:20 p.m. and 7:12 p.m. EDT Aug. 26 with Hubble’s Wide Field and Planetary Camera 2.

Reflected sunlight from Mars at these wavelengths shows scattering by atmospheric molecules and haze, while the polar ice caps and some surface features are also visible. Hubble and MAVEN showed that Martian atmospheric conditions change very quickly.

Aug 27, 2003 · This view of Mars from the Hubble Space Telescope's new Advanced Camera for Surveys provides the sharpest view of the red planet attainable by the Earth-oribiting observatory. The picture was taken August 24, when Mars was approximately 34.7 million miles (or 55.8 million kilometres) from Earth.

Jul 21, 2001 · NASA's Earth-orbiting Hubble Space Telescope took the picture on June 26, when Mars was approximately 43 million miles (68 million km) from Earth -- the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 10 miles (16 km) across.

Jul 26, 2018 · NASA’s Hubble Space Telescope photographed Mars on July 18, near its closest approach to Earth since 2003. The planet was observed near opposition, when the Sun, Earth and Mars are lined up, with Earth sitting in between the Sun and Mars.

Jun 17, 2019 · Over the decades of its mission, the Hubble Space Telescope has observed our closest planetary neighbor, Mars, documenting its seasons, terrain, and storms. Hubble’s work complements that of spacecraft and lander missions to the Red Planet, making Mars the most observed world other than Earth.
