Originally Mariner H was assigned a basic mission objective of mapping 70% of Mars and Mariner I a mission objective of studying changes in the atmosphere and on the surface over a period of time (variable features mission). This has been achieved by selection of inclination, period and periapsis and will also be a key factor in budgeting of time for the various objectives during the 90 days at Mars. The orbit will give good planet coverage at a 65-degree inclination from the Martian equator, with highest resolution from South to North at low orbit. Following the successsful launch phase of the mission, the spacecraft was prepared for the maneuver by venting the propulsion subsystem's propellant lines.

For the survey portion of the mission, the planetary surface was The propellant was monomethyl hydrazine and nitrogen tetroxide. Original plans called for the probes to be launched on the Atlas-Centaur, but serious developmental problems with that vehicle forced a switch to the much smaller Agena B second stage.

Due to a series of malfunctions, the spacecraft missed the Moon by 22,000 mi (35,000 km) and entered a heliocentric orbit. duration), 5:29:12 end yaw, unwind (sun acquisition) start roll unwind (13 minute, 25 second duration), 5:45:37 end roll unwind (Canopus acquisition), Earth Time ~W~V change, All others spacecraft time 6.731 meters per sec. atmosphere.

As the planet occults--that is, intercepts--the spacecraft radio signal, it will be possible for scientists to get such information, plus measurements of atmospheric and ionospheric density and pressure. Recurring phenomena such as dust storms, clouds and seasonal changes in the appearance of the planet's surface have been observed on Mars. On 5 February 2019, NASA reported that both the CubeSats had gone silent by 5 January 2019, and are unlikely to be heard from again. Both Phobos and Deimos could be shedding trails of dust in near-Martian space. Both Earth and Mariner 9 are moving around the Sun together with the spacecraft traveling faster and moving away from the orbit of Earth towards the orbit of Mars. Attitude knowledge was provided by a Sun sensor, a Canopus star tracker, gyroscopes, an inertial reference unit, and an accelerometer. Mars 1M was a series of two unmanned spacecraft which were used in the first Soviet missions to explore Mars.
Shortly after takeoff the rocket responded improperly to commands from the guidance systems on the ground, setting the stage for an apparent software-related guidance system failure. The storm quickly grew into one of the largest of the frame. However "Express" also describes the spacecraft's relatively short interplanetary voyage, a result of being launched when the orbits of Earth and Mars brought them closer than they had been in about 60,000 years. Mariner Project officials at the Jet Propulsion Laboratory in Pasadena, Calif., said the planned maneuver requires a velocity change of 15.7 miles per hour (seen meters per second). Velocity (relative to Earth) at time of motor burn 6,838 MPH. An investigation into the cause of a Centaur stage failure was begun immediately after the unsuccessful first attempt to launch a Mariner Mars (Mariner H) mission on May 8. Playback could be done at 16, 8, 4, 2, and 1 kbit/s using two tracks at a time.

Nozomi was a Mars orbiter that failed to reach Mars due to electrical failures. A planned midcourse maneuver was executed on 5 June. Mariner 1 was the first spacecraft of the American Mariner program, designed for a planetary flyby of Venus.

A 15 minute 23 second rocket burn put Mariner's rounds will carry it between Phobos, which orbits Mars about 4,000 miles out, and Deimos, at 12,000 miles.

It was launched aboard an Atlas-Agena rocket on July 22, 1962. The Mariner 2 spacecraft was launched from Cape Canaveral on August 27, 1962, and passed as close as 34,773 kilometers (21,607 mi) to Venus on December 14, 1962. A total of 54 billion bits of scientific data were returned, including 7329 images A scan platform was mounted on the bottom of the frame, on which were attached the mutually bore-sighted science instruments (wide- and narrow-angle TV cameras, infrared radiometer, ultraviolet spectrometer, and infrared interferometer spectrometer). The integrated circuit or chip was in the pitch channel of the rate gyro preamplifier in the Centaur stage autopilot.
The 12 hour period was selected to insure a maximum data return of two tapeloads per day. The Martian surface is to be examined by photography and in the infrared wavelengths. (15.08 miles per hour). the spacecraft into Mars orbit, making Mariner 9 the first spacecraft to orbit another
