  Sinus Meridiani - Wikipedia, the free encyclopedia
Sinus Meridiani is a classic albedo feature on Mars stretching east-west just south of that planet's equator.
The area was named by the French astronomer Camille Flammarion in the late 1870s when he worked on his compilation and analysis of all prior observations of Mars.
Sinus Meridiani consequently became also known as Terra Meridiani, or "Meridian Land", or as Meridiani Planum, the "Meridian Plateau".

 Meridiani Planum - Wikipedia NL
Meridiani Planum is een vlakte die zich 2 graden ten zuiden van de Mars -evenaar, bevindt, in het westelijk deel van Sinus Meridiani.
Hierom denken veel wetenschappers dat het hematiet op Meridiani Planum een indicatie kan zijn dat er vroeger water te vinden was op Meridiani Planum.
Het hematiet is deel van een gelaagde sedimentaire rotslaag die naar schatting zo'n 200 meter dik is. Andere kenmerken van Meridiani Planum zijn vulkanisch basalt en inslagkraters.

Meridiani Planum è una pianura situata 2 gradi a sud dell' equatore di Marte, nella parte più a ovest del Sinus Meridiani.
Sulla Terra l'ematite si forma in sorgenti termali o in pozze d'acqua stagnanti; quindi, molti scienziati ritengono che l'ematite della Meridiani Planum possa essere indicativa della presenza di antiche sorgenti termali o della presenza di acqua liquida sul pianeta.
Altre caratteristiche di Meridiani Planum includono basalto vulcanico e crateri da impatto.

Amongst the findings from the Opportunity rover is the presence of hematite on Mars in the form of small spheres on the Meridiani Planum.
This and other evidence lead a group of 50 scientists to conclude in the December 9, 2004 edition of the journal Science that "Liquid water was once intermittently present at the martian surface at Meridiani, and at times it saturated the subsurface.
Because liquid water is a key prerequisite for life, we infer conditions at Meridiani may have been habitable for some period of time in martian history".

For this reason, the announcement in 2000 of the discovery of crystalline gray hematite near the Martian equator was, in a word, a watershed for planetary geologists and astrobiologists interested in unraveling the history of water and climate on Mars.
Detection of the hematite in Terra Meridiani is one of the key discoveries of the Thermal Emission Spectrometer (TES) instrument on the Mars Global Surveyor (MGS) mission.
Terra Meridiani is a leading candidate for further exploration by one of the upcoming Mars Exploration Rovers (MER) because of its distinctive mineralogy and its relative safety as a landing site (in terms of low wind shear, low abundance of boulders, and low slope angles).

Meridiani is likely to have a more grey, volcanic look to it than Gusev's flat plain, but with intriguing possibilities for also having a water-formed history and an aqueous mineral called hematite.
The rock density at Meridiani is also hoped to be less than twenty percent of the landscape, which will make driving longer distances possible.
"My favorite is Terra Meridiani, because hematite mineral concentrations are detected there, possibly due to hydrothermal activity, and our crater studies (with Dr. Melissa Lane in our group) suggest a very old surface (a lakebed?) that was only recently exhumed".

Meridiani Planum interests scientists because it contains an ancient layer of hematite, an iron oxide that, on Earth, almost always forms in an environment containing liquid water.
Meridiani Planum is unique on Mars because there's so much exposed hematite there, according to data gathered by NASA's Mars Global Surveyor spacecraft.
Meridiani Planum is also attractive because the site appears to be eroding, with once-buried craters that are now half-revealed.

 Uncovering The Meridiani Formation
But there was one glaring exception to Mars' mineralogical blandness: a huge area in the Sinus Meridiani region, 350 by 750 km wide, which shows clear spectral signs of a coarse-grained variety of the iron oxide mineral hematite.
The Sinus Meridiani hematite patch is in a smooth plains area, which seems to consist of several different layers of differing rock deposited at different times, with the hematite just being one of those layers.
In Sinus Meridiani, we may have a unique "snapshot" of what the watery regions of ancient Mars were like.
