Spirit, also known as MER-A (Mars Exploration Rover – A) or MER-2, is a Mars robotic rover, active from 2004 to 2010. Spirit was operational on Mars for 2208 sols or 3.3 Martian years (2269 days; 6 years, 77 days). It was one of two rovers of NASA's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL). Spirit landed successfully within the impact crater Gusev on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, Opportunity (MER-B), which landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover got stuck in a "sand trap" in late 2009 at an angle that hampered recharging of its batteries; its last communication with Earth was on March 22, 2010.
The rover completed its planned 90-sol mission (slightly less than 92.5 Earth days). Aided by cleaning events that resulted in more energy from its solar panels, Spirit went on to function effectively over twenty times longer than NASA planners expected. Spirit also logged 7.73 km (4.8 mi) of driving instead of the planned 600 m (0.4 mi), allowing more extensive geological analysis of Martian rocks and planetary surface features. Initial scientific results from the first phase of the mission (the 90-sol prime mission) were published in a special issue of the journal Science.On May 1, 2009 (5 years, 3 months, 27 Earth days after landing; 21 times the planned mission duration), Spirit became stuck in soft sand. This was not the first of the mission's "embedding events" and for the following eight months NASA carefully analyzed the situation, running Earth-based theoretical and practical simulations, and finally programming the rover to make extrication drives in an attempt to free itself. These efforts continued until January 26, 2010, when NASA officials announced that the rover was likely irrecoverably obstructed by its location in soft sand,
though it continued to perform scientific research from its current location.The rover continued in a stationary science platform role until communication with Spirit stopped on March 22, 2010 (sol 2208). JPL continued to attempt to regain contact until May 24, 2011, when NASA announced that efforts to communicate with the unresponsive rover had ended, calling the mission complete. A formal farewell took place at NASA headquarters shortly thereafter.

Fay Owen "Buster" Welch (May 23, 1928 – June 12, 2022) was an American cutting horse trainer and inductee into the NCHA Members Hall of Fame, American Quarter Horse Hall of Fame, NCHA Rider Hall of Fame, and Texas Cowboy Hall of Fame. Buster was chosen as the recipient of the 2012 National Golden Spur Award for his "outstanding contributions to the ranching and livestock industry".
Buster won the NCHA World Championship four times, and the NCHA World Championship Futurity five times. The most notable horses he trained include Marion's Girl, Chickasha Mike, Money's Glo who he trained and in 1962 won the first NCHA World Championship Futurity, in 1963 he won it on Chickasha Glo, in 1966 on Rey Jay's Pete, in 1971 on Dry Doc, and in 1977 on Peppy San Badger. He won the NCHA World Championship on Marion's Girl in 1954 and 1956. He trained Mr San Peppy and won the NCHA World Championship in 1974 and 1976.
