![<h1>PIA02995: Nix Olympica Identified by Mariner 9 on Mars Approach</h1><div class="PIA02995" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;"><p>The most conspicuous feature yet observed on Mars by Mariner 9 is the darkish spot located near the top of this picture. It has been tentatively identified as Nix Olympica, a curious ring-shaped feature photographed by Mariners 6 and 7 in 1969 and a point which radar indicates is one of the highest on Mars. One possible explanation suggests a high mountain or plateau which is being seen as it rises up through the bright dust surrounding the rest of the planet. The picture, one of a series of 31 recorded on the first tape-load during approach to Mars, was taken at 8:46 a.m. PST, November 11, 1971, at a range of about 408,000 miles. North is at the top.<p>Mariner 9 was the first spacecraft to orbit another planet. The spacecraft was designed to continue the atmospheric studies begun by Mariners 6 and 7, and to map over 70% of the Martian surface from the lowest altitude (1500 kilometers [900 miles]) and at the highest resolutions (1 kilometer per pixel to 100 meters per pixel) of any previous Mars mission.<p>Mariner 9 was launched on May 30, 1971 and arrived on November 14, 1971.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA02995" onclick="window.open(this.href); return false;" title="Voir l'image PIA02995: Nix Olympica Identified by Mariner 9 on Mars Approach sur le site de la NASA">Voir l'image PIA02995: Nix Olympica Identified by Mariner 9 on Mars Approach sur le site de la NASA.</a></div>](tl_files/photos/Mars/2-Mariner/PIA02995.jpg)

The south polar cap (at the bottom of the planet disc) shines dimly through the apparent atmospheric haze, probably dust. This was the fourteenth picture taken during a 24-hour series of Mars surveillance photos. The picture was taken with Mariner's narrow-angle camera from a distance of 445,000 miles. The "dust storm" has obscured the usually prominent Martian surface features from ground-based observers for several months.<p>Mariner 9 was the first spacecraft to orbit another planet.

The picture has been computer-enhanced with electronic high-pass filtering. The crater-like object at the lower left is about 124 miles (200 kilometers) across and is the same dark spot seen earlier in more distant views. It can be identified on a Mars map as Arsia Silva. The streaks pointing north--more than 1000 kilometers long--are either atmospheric turbulence patterns or dunes formed downwind of the crater. If they are dunes, they are as extensive as the largest in the Sahara in North Africa and those in Peru, South America. The picture was taken from a distance of 65,000 miles about eight hours before Mariner 9 went into orbit around Mars. It was transmitted back to Earth at 10:00 p.m. during the first orbit.<p>Mariner 9 was the first spacecraft to orbit another planet.

This higher resolution photograph shows that the area contains a complex crater, called Olympus Mons (Nix Olympica or Snows of Olympus), nearly 64 kilometers (40 miles) in diameter. The multiple crater form with scalloped margins, is characteristic of calderas--volcanic collapse depressions on Earth. In the Mariner 6 and 7 flights in 1969, an outer ring, 1600 kilometers (1,000 miles) in diameter, was seen. It is hidden by the dust in the oblique picture. Earth-based radar observations show that this is a high region on Mars and is usually covered by a white cloud when observed telescopically. This picture was taken on November 27, 1971.<p>Mariner 9 was the first spacecraft to orbit another planet.

It is the northernmost of the prominent dark spots observed by Mariner during its approach to the planet. The spot consists of several intersecting shallow crater-like depressions. The main crater is approximately 21 kilometers (13 miles) across, the whole complex about 40 kilometers (25 miles) across. The crater probably is in a relatively high area of the Martian surface, which accounts for its being visible above the dust storm. The faint circular features outside the crater are probably atmospheric.<p>Mariner 9 was the first spacecraft to orbit another planet.

Hubble can see details as small as 10 miles (16 km) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope.<p>Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap [top of image], and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere [lower right].<p>Hubble has observed Mars before, but never in such detail. The biennial close approaches of Mars and Earth are not all the same. Mars' orbit around the Sun is markedly elliptical; the close approaches to Earth can range from 35 million to 63 million miles.<p>Astronomers are interested in studying the changeable surface and weather conditions on Mars, in part, to help plan for a pair of NASA missions to land rovers on the planet's surface in 2004.<p>The Mars opposition of 2001 serves as a prelude for 2003 when Mars and Earth will come within 35 million miles of each other, the closest since 1924 and not to be matched until 2287.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA03154" onclick="window.open(this.href); return false;" title="Voir l'image PIA03154: Hubble Captures Best View of Mars Ever Obtained from Earth sur le site de la NASA">Voir l'image PIA03154: Hubble Captures Best View of Mars Ever Obtained from Earth sur le site de la NASA.</a></div>](tl_files/photos/Mars/2-hubble/PIA03154.jpg)
