Mars as photographed by the Hubble telescope.
Mars is the fourth planet from the Sun in our solar system. It is named after the Roman god of war Mars (Ares in Greek mythology) because of its apparent red color. This feature has also earned it the nickname "The Red Planet". The prefix areo- refers to Mars in the same way geo- refers to Earth. The astronomical symbol for Mars is ♂, a circle with an arrow pointing northeast. The Chinese, Korean, Japanese, and Vietnamese cultures refer to the planet as 火星, or fire star. Mars is a terrestrial planet with a thin atmosphere, having surface features such as craters, giant valleys, and volcanoes. Of all the planets in our Solar System other than Earth, Mars is the most likely to harbor liquid water, and perhaps life.

Mars Reconnaissance Orbiter
NASA's Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit. The $720 million USD spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory. It was launched August 12, 2005, and attained Martian orbit on March 10, 2006. It finished aerobraking, entered its final science orbit and began its primary science phase in November 2006.

MRO contains a host of scientific instruments such as cameras, spectrometers, and radar, which are used to analyze the landforms, stratigraphy, minerals, and ice of Mars. It paves the way for future spacecraft by monitoring daily weather and surface conditions, studying potential landing sites, and testing a new telecommunications system. MRO's telecommunications system will transfer more data back to Earth than all previous interplanetary missions combined, and MRO will serve as a highly capable relay satellite for future missions.

Selected biography

Percival Lowell
Percival Lawrence Lowell (March 13, 1855 – November 12, 1916) was a businessman, author, mathematician, and astronomer who fueled speculation that there were canals on Mars, founded the Lowell Observatory in Flagstaff, Arizona, and formed the beginning of the effort that led to the discovery of Pluto 14 years after his death. The choice of the name Pluto and its symbol were partly influenced by his initials PL.

Percival Lowell, a descendant of the Boston Lowell family, was the brother of A. Lawrence, president of Harvard University, and Amy, an imagist poet, critic, and publisher. Percival graduated from the Noble and Greenough School in 1872 and Harvard University in 1876 with distinction in mathematics. At his college graduation, he gave a speech, considered very advanced for its time, on the "Nebular Hypothesis." He was later awarded honorary degrees from Amherst College and Clark University.

Unusual hole in Mars
Credit: NASA

The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image right. Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep. .
