	Mars Climate Orbiter - Wikipedia, the free encyclopedia
		Mars Climate Orbiter was launched on a Delta 7425 (a Delta II Lite launch vehicle with four strap-on solid rocket boosters and a Star 48 (PAM-D) third stage).
		The orbiter was to begin aerobraking, using the solar panel to provide resistance and continue until a 90 × 405 km orbit was achieved, nominally on 22 November 1999, with periapsis at 89 N. The hydrazine thrusters would be used to change the orbit to a 2-hour, 421 km near-circular polar science mapping orbit on 1 December 1999.
		At the end of the mapping mission on 15 January 2002, the orbiter was to be placed in a stable orbit and function as a UHF relay for the Mars 2001 mission.

	Mars Climate Orbiter
		The Mars Surveyor '98 program is comprised of two spacecraft launched separately, the Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) and the Mars Polar Lander (formerly the Mars Surveyor '98 Lander).
		The Mars Climate Orbiter was destroyed when a navigation error caused it to miss its target altiude at Mars by 80 to 90 km, instead entering the martian atmosphere at an altitude of 57 km during the orbit insertion maneuver.
		Mars Climate Orbiter was launched on a Delta 7425 (a Delta II Lite launch vehicle with four strap-on solid-rocket boosters and a Star 48 (PAM-D) third stage).

	Mars Climate Orbiter - Aerobraking (Site not responding. Last check: 2007-10-23)
		Mars Climate Orbiter will be starting from an orbit much lower than Mars Global Surveyor - with an orbit period only one-third as long - so it will require much less aerobraking.
		If Mars Climate Orbiter is launched within the first eight days of its launch period, it will be able to reach its final science-gathering orbit at least two weeks before Mars Polar Lander arrives.
		Although the orbiter's transmitter may be on continuously during aerobraking, contact with Earth will not be possible during the aeropasses or when the spacecraft passes behind Mars as seen from Earth.

		The MCO was to have used a technique called aerobraking, which uses a planet's atmospheric friction to reduce the spacecraft's velocity (See Appendix 1).
		"Mars Climate Orbiter's first assignment after it completes aerobraking will be to serve as the communications relay for its sibling spacecraft, Mars Polar Lander, set to land near the south pole on December 3." (p3, [5]).
		The root cause for the loss of the Mars Climate Orbiter in September 1999, was due to the failure to convert the outputted Imperial measurements to the required metric measurements, within a specific piece of ground software.

	Software Engineering: Mars Climate Orbiter
		The Mars Climate Orbiter was part of an extended series of missions conducted by NASA to expore Mars during an extended period when Mars and Earth's orbits brought them into relative proximity.
		Subsequent analysis of the failure determined that the principle cause of the failure was confusion in units, instead of sending thrust information to the orbiter in Newtons, the instructions were in pounds, a factor of 2.2 times greater.
		These instructions were used by the orbiter's earth based navigation controllers to adjust the craft's aspect during the voyage in order to compensate for changes caused by the assymmetry of the orbiter and pressure from the solar wind on the panels.
