circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms cardiovascular...

Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet...

principle cannot be driven by inviscid axisymmetric circulations. Assimilated data and general circulation model (GCM) simulation suggest that super-rotating...

Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns...

average gravitational acceleration on Mars is 3.728 m/s2 (about 38% of the gravity of Earth) and it varies. In general, topography-controlled isostasy drives...

measurements from the MOLA instrument, Mars Climate Sounder (MCS), and the Martian General Circulation Model (MGCM), point to cloud formations on the...

Mars may contain ores that would be very useful to potential colonists. The abundance of volcanic features together with widespread cratering are strong...

Hellenistic astronomers developed a geocentric model to explain the planet's motions. Measurements of Mars' angular diameter can be found in ancient Greek...

The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body...

perturbations on Mars by asteroids have caused problems, they have also been used to estimate the masses of certain asteroids. But improving the model of the asteroid...

The colonization of Mars is the proposed process of establishing permanent human settlements on the planet Mars. Most colonization concepts focus on settling...

The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the planet's geologic history...

Rain and snow were regular occurrences on Mars in the past; especially in the Noachian and early Hesperian epochs. Water was theorized to seep into the...

Olympus') is a large shield volcano on Mars. It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), about...

The possibility of life on Mars is a subject of interest in astrobiology due to the planet's proximity and similarities to Earth. To date, no conclusive...
