Nobody wants popcorn on their ceilings. Like cork walls, mirror tiles and avocado- green shag carpet, acoustic ceiling texture was all the rage in the 1970s and 1980s. Builders of thousands of new Colorado homes relied on it for a quick, inexpensive finish.
Differing in situ values have been reported for the average temperature on Mars, with a common value being â55 Â°C (218 K; â67 Â°F). Surface temperatures may reach a high of about 20 Â°C (293 K; 68 Â°F) at noon, at the equator, and a low of about â153 Â°C (120 K; â243 Â°F) at the poles.
But Mars is a cold planet now; the average recorded temperature on Mars is -63Â° C (-81Â° F) with a maximum temperature of 20Â° C (68Â° F) and a minimum of -140Â° C (-220Â° F).The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including the two Viking landers in 1976.he average pressure on the surface of Mars is only about 7 millibars (less than 1% of Earthâs), but it varies greatly with altitude from almost 9 millibars in the deepest basins to about 1 millibar at the top of Olympus Mons.
