Mars Polar Lander / Deep Space 2

Mars Polar Lander was designed to study climate and subsurface ice near Mars' south polar cap, while the two piggyback Deep Space 2 microprobes were intended to impact nearby and test miniature penetrator technologies. All three flight elements shared a cruise stage but separated for independent arrivals.

Launch Site
Outcome
No signal was received from Mars Polar Lander or either Deep Space 2 probe after arrival. The lander investigation identified premature engine shutdown triggered by a likely false touchdown indication as the leading explanation; the probes' individual failure causes could not be determined.
