Mars Observer was scheduled to perform an orbital insertion maneuver on August 24, 1993, but contact with the spacecraft was lost on August 21, 1993. The likely reason for the spacecraft failure was the leakage of fuel and oxidizer vapors through the improperly designed PTFE check valve to the common pressurization system.
Mars Observer was a robotic spacecraft designed to study the geoscience and climate of Mars. The first of the proposed Observer series of planetary missions, it was launched by NASA on September 25, 1992. Three days before Mars Observer was scheduled to enter the orbit of Mars, contact with the spacecraft was lost. Attempts to re-establish ...
The orbiter reached Mars orbit on September 24, 2014. Through this mission, ISRO became the first space agency to succeed in its first attempt at a Mars orbiter. The mission is the first successful Asian interplanetary mission. [6] Ten days after ISRO's launch, NASA launched their seventh Mars orbiter MAVEN to study the Martian atmosphere.
After the loss of Mars Observer and the onset of the rising costs associated with the future International Space Station, NASA began seeking less expensive, smaller probes for scientific interplanetary missions. In 1994, the Panel on Small Spacecraft Technology was established to set guidelines for future miniature spacecraft.
The Mars Orbiter Camera was in orbit around Mars between 1997 and 2006 (narrow-angle camera inside the cylinder, the two wide-angle cameras attached on the front area). The Mars Orbiter Camera and Mars Observer Camera (MOC) were scientific instruments on board the Mars Observer and Mars Global Surveyor spacecraft.
The Mars Orbiter Camera (MOC) operated by Malin Space Science Systems – The Mars Orbiter Camera (MOC), originally known as Mars Observer Camera, [9] [10] used 3 instruments: a narrow angle camera that took (black-and-white) high resolution images (usually 1.5 to 12 m per pixel) and red and blue wide angle pictures for context (240 m per pixel ...

MESUR was a planned set of 16 surface missions on Mars that would also set up a planetary network across Mars and work in conjunction with Mars Observer. [1] The original plan was proposed by NASA Ames, [2] but it would eventually include ideas from the competing JPL proposal. It was envisioned as a low-cost method of surveying Mars, with risk ...
