Endurance \En*dur"ance\, n. [Cf. OF. endurance. See Endure.]

1. A state or quality of lasting or duration; lastingness; continuance.

   Slurring with an evasive answer the question concerning the endurance of his own possession.
   --Sir W. Scott.

2. The act of bearing or suffering; a continuing under pain or distress without resistance, or without being overcome; sufferance; patience.

   Their fortitude was most admirable in their patience and endurance of all evils, of pain and of death.
   --Sir W. Temple.

   Syn: Suffering; patience; fortitude; resignation.

late 15c., "continued existence in time;" see endure + -ance. Meaning "ability to bear suffering, etc." is from 1660s.

n. 1 The measure of a person's stamina or persistence. 2 Ability to endure hardship.

1. n. the power to withstand hardship or stress; "the marathon tests a runner's endurance"

2. a state of surviving; remaining alive [syn: survival]

Endurance is an impact crater lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This crater was visited by the Opportunity rover from May until December 2004. Mission scientists named the crater after the ship Endurance that sailed to the Antarctic through the Weddell Sea during the ill-fated 1914-1917 Imperial Trans-Antarctic Expedition, considered to be the last expedition of the Heroic Age of Antarctic Exploration organized by Ernest Shackleton.

The rover entered the crater interior on its 134th mission sol (June 15), and exited on the 315th sol (December 14). During this time it traversed various obstacles, steep inclines, and overcame large wheel slippage when driving over fine sand. __TOC__

Endurance is a 1999 docudrama film about the famous distance runner Haile Gebrselassie with Gebrselassie playing the role of himself.

It was written and directed by Leslie Woodhead and Bud Greenspan, and produced and released by Walt Disney Pictures. The movie features Gebrselassie's upbringing in Ethiopia and his subsequent triumph in the 10,000-meter track event in the Atlanta Olympic Games of 1996.

The movie was released on DVD on January 31, 2012.

ENDURANCE (Environmentally Non-Disturbing Under-ice Robotic Antarctic Explorer) is an autonomous underwater vehicle designed to map in three dimensions the geochemistry and biology of underwater terrains in Antarctica. The vehicle was built and designed by Stone Aerospace, and is the second incarnation of the DEPTHX vehicle, which was significantly reconfigured for the challenges particular to the Antarctic environment.

The principal investigator for the ENDURANCE project was Earth and environmental scientist Dr. Peter Doran of the University of Illinois at Chicago. Bill Stone, CEO of Stone Aerospace, was a co-investigator, along with Dr. John Priscu of Montana State University, and Dr. Chris McKay of NASA Ames Research Center. The project was funded by the NASA ASTEP program as well as by the National Science Foundation's United States Antarctic Program.

The name of ENDURANCE is a backronym in tribute to Ernest Shackleton's Antarctic exploration ship Endurance.

Endurance was an American reality television children's program, previously shown on the Discovery Kids cable network in the United States and also on networks in other countries. The show's format is somewhat similar to the CBS television series Survivor, though with a teenaged cast (however, there are more elements of the U.S. version of Big Brother). Endurance contestants live in a remote location and participate in various mental and physical challenges, although Endurance contestants compete as pairs (one boy and one girl), and the outcome of the competitions determines which pair of players is eliminated.

In its six-year run between 2002 through 2008, each season began with a new slate of contestants, who were gradually eliminated as the season progressed until the remaining two teams competed to get all of the Endurance Pyramid pieces. The winning boy and girl received an all-expenses paid vacation package with their parents to an exotic location as the prize.

Production ended with the final episode of the sixth season, first aired on June 28, 2008. Reruns of Endurance continue to be televised in the U.S., on Hub Network, Discovery Kids' successor until July 22, 2013. Spanish-dubbed reruns also air on weekends on Azteca America. Three seasons of Endurance (Hawaii, Tehachapi and High Sierras) were each nominated for a Daytime Emmy Award in the category of "Outstanding Children's Series", however the show never won.

Endurance (or stamina) is the act of sustaining prolonged stressful effort.

• Endurance (aircraft), the maximum length of time an aircraft can stay in flight

In aviation, endurance is the maximum length of time that an aircraft can spend in cruising flight. Endurance is different from range, which is a measure of distance flown. For example, a typical sailplane exhibits high endurance characteristics but poor range characteristics.

Endurance can be defined as:

$E=\int_{t_1}^{t_2}dt=-\int_{W_1}^{W_2}\frac{dW}{F}=\int_{W_2}^{W_1}\frac{dW}{F}$

where W stands for fuel weight, F for fuel flow, and t for time.

Endurance can factor into aviation design in a number of ways. Some aircraft, such as the P-3 Orion or U-2 spy plane, require high endurance characteristics as part of their mission profile (often referred to as loiter time (on target)). The Endurance plays a prime factor in finding out the fuel fraction for an aircraft. The Endurance, like range, is also related to fuel efficiency; fuel-efficient aircraft will tend to exhibit good endurance characteristics.
