Mariner 10 was the seventh successful launch in the Mariner series and the first spacecraft to visit Mercury. The program included a number of firsts, including the first planetary flyby, the first planetary orbiter, and the first gravity assist … Mariner 10.
Mariner 10 flew past Venus on February 5, 1974, at a distance of 4,200 kilometers (2,610 miles). It showed close-up pictures of the sun's closest planetary neighbor and also did investigations of Mercury's environment and surface. Mariner 10 software are given in the Appendix.
The spacecraft passed Venus on February 5, 1974, at a distance of 4200 Km. On November 3, 1973, Mariner 10 was placed in a parking orbit after launch for approximately 25 minutes, then placed in orbit around the Sun en route to Venus. The program launched a series of robotic interplanetary probes, from 1962 to 1973, designed to investigate Mars, Venus and Mercury.
Mercury - Mercury - Mariner 10, radar, and Messenger: Scientific knowledge about Mercury was greatly increased by the three flybys of Mariner 10. (see Reference 3). A nighttime lift-off of the Atlas … Assembly. During its two-year mission, the spacecraft transmitted over 12,000 images of Mercury and Venus. Mariner 10 was placed in a parking orbit after launch for approximately 25 minutes, then placed in orbit around the Sun en route to Venus.
The Mariner program was a 10-mission program conducted by the American space agency NASA in conjunction with Jet Propulsion Laboratory (JPL).
Mariner 10 is still orbiting the sun, even though its electronic systems have probably been destroyed by solar radiation. I. Premission Analysis and Plannin~ An accuracy analysis study was conducted prior to the ~'.ssion in order to determine the accurate capabilities of the orbit determination (O.D.) system. It crossed the orbit of Mercury on March 29, 1974, at 2046 UT, at a distance of … The orbit direction around the Sun was opposite to that of the Earth. Because the spacecraft was placed in an orbit around the Sun equal to one Mercurian solar day, it made each of its three passes when exactly the same half of the planet was in sunlight. The orbit direction was opposite to the motion of the Earth around the Sun. The spacecraft flew by Mercury three times in a retrograde heliocentric orbit and returned images and data on the planet. Liftoff. Mariner 10 was the first spacecraft to visit Mercury. Slightly less than the illuminated half, or about 45 percent of Mercury’s surface, … Here the Mariner 10 spacecraft is being assembled prior to its November 1973 launch. Mid-course corrections were made. It was also the first spacecraft to use the gravitational pull of one planet (Venus) to reach another (Mercury), and the first spacecraft mission to visit two planets. The mission ended in March 1975. Mariner 10 … More than 4,000 photos of Venus revealed a nearly round planet enveloped … This study concentrated on the prime mission, i.e., up to the first Mercury encounter.
