Mars red

MARS RED (1309-37-1) Violent reactions with powdered aluminum (thermite reaction), hydrogen peroxide, calcium disilicide (thermite reaction), ethylene oxide (may cause explosive polymerization), calcium hypochlorite, hydrazine, hydrogen trisulfide, powdered magnesium. Incompatible with powdered calcium carbide, carbon monoxide, chlorides,...

A group of synthetically produced iron oxide pigments with colours in the yellow-red-violet-black range, the term typically qualified by a colour descriptor (such as Mars red ). The mars colours emerged in the eighteenth century.

Mars red is one of the mars pigments (. v.), developed during the eighteenth century and manufactured by the aqueous precipitation of iron salts (sulfates, chlorides, nitrates and acetates) with an alkali (lime, caustic soda (NaOH), potash, etc.). Mars red was produced by roasting the precipitate produced by this process,... 

Helwig (1998) identified the presence of chrome orange, hematite and goethite in mars red supplied by the Belgian firm of Blockx et fils (1865 1913). 

Mars scarlet was apparently a form of mars red (q.v.), Carlyle (2001) notes that Winsor Newton began listing this pigment in 1846, while Roberson purchased it from the colour-men Lechertier Barbe in 1872.

Fig. 3.21 Example of temperature variation as measured by MIMOS II temperature sensors on MER (i) inside the rover body at MIMOS electronics board (black curve), (ii) outside the rover, at the MIMOS II SH (green and red curves), which is at ambient Martian temperature (a) inside the sensor-head, at the reference absorber position (green), (b) outside the SH at the sample s contact plate (red). Temperatures at the two SH positions are nearly identical (difference less than 2 K). During data transmission between the rover and the Earth (or the relay satellite in Mars orbit) the instrument is switched off resulting in immediate small but noticeable temperature changes (see figure above)...

In about 4 billion years our sun will also develop into a red giant. The diameter will then reach the orbit of Mars, and the inner planets will cease to exist. 

In spite of many new, and in some cases sensational, results concerning the Red Planet, we are still no nearer to answering the question of life on Mars. Four alternatives appear possible for Mars ... 

This makes it clear that a vast amount of work must still be done on Mars in order to obtain a final answer as to whether life exists, or ever existed, on the Red Planet.
