Mars rover

A Mars rover is an automated motor vehicle that propels itself across the surface of the planet Mars upon arrival. Rovers have several advantages over stationary landers: they examine more territory, and they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very remote robotic vehicle control.

There have been four successful robotically operated Mars rovers. The Jet Propulsion Laboratory managed the Mars Pathfinder mission and its now inactive Sojourner rover. It currently manages the Mars Exploration Rover mission's active Opportunity rover and inactive Spirit, and, as part of the Mars Science Laboratory mission, the Curiosity rover.

On January 24, 2014, NASA reported that current studies on the planet Mars by the Curiosity and Opportunity rovers will now be searching for evidence of ancient life, including a biosphere based on autotrophic, chemotrophic, and/or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments (plains related to ancient rivers or lakes) that may have been habitable. The search for evidence of habitability, taphonomy (related to fossils), and organic carbon on the planet Mars is now a primary NASA objective.

University

A university (Latin: universitas, "a whole") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects and typically provides undergraduate education and postgraduate education. The word "university" is derived from the Latin universitas magistrorum et scholarium, which roughly means "community of teachers and scholars."

History

Definition

The original Latin word "universitas" refers in general to "a number of persons associated into one body, a society, company, community, guild, corporation, etc." At the time of the emergence of urban town life and medieval guilds, specialised "associations of students and teachers with collective legal rights usually guaranteed by charters issued by princes, prelates, or the towns in which they were located" came to be denominated by this general term. Like other guilds, they were self-regulating and determined the qualifications of their members.

In modern usage the word has come to mean "An institution of higher education offering tuition in mainly non-vocational subjects and typically having the power to confer degrees," with the earlier emphasis on its corporate organization considered as applying historically to Medieval universities.

State university system

A state university system in the United States is a group of public universities supported by an individual state, or a similar entity such as the District of Columbia. These systems constitute the majority of public-funded universities in the country. Each state supports at least one such system.

State university systems should not be confused with federally funded colleges and universities, at which attendance is limited to military personnel and government employees. Members of foreign militaries and governments also attend some schools. These schools include the United States military academies, Naval Postgraduate School, and military staff colleges.

A state university system normally means a single legal entity and administration, but may consist of several institutions, each with its own identity as a university. Some states—such as California and Texas—support more than one such system.

State universities get subsidies from their states. The amount of the subsidy varies from university to university and state to state, but the effect is to lower tuition costs below that of private universities for students from that state or district. As more and more Americans attend college, and private tuition rates increase well beyond the rate of inflation, admission to state universities is becoming more and more competitive.
