Mariner 2 flew past the planet Venus in 1962, becoming the first spacecraft to successfully encounter another planet. It provided valuable information about Venus's atmosphere and surface temperature.
Mariner 2 in 1962. The planet was Venus.
That statement is incorrect. Mariner 2 was the first spacecraft to successfully fly by and study another planet, Venus, not scan. It provided valuable data on Venus' atmosphere and surface temperature.
Mariner 4 returned close-range images of Mars in July 1965. It was the first spacecraft to successfully fly by and image another planet. The images provided valuable information about the Martian surface.
Mariner 10, launched on November 3, 1973, studied Mercury and Venus. After passing Venus in February, 1974, it did an extremely close fly-by of Mercury on March 29, 1974, passing within 437 miles (703 km) of the surface. It made two more flyby passes in September, 1974 and March, 1975. The third flyby was even closer than the first one, coming within 203 miles (327 km) of Mercury.Unfortunately, the limited solar orbit of the probe meant that each of the three passes observed the same hemisphere of Mercury illuminated by the Sun. Only about 45% of the surface was photographically mapped.The geography of Mercury will be extensively detailed by the new MESSENGER spacecraft, which has already flown by Mercury three times since its launch in 2004, and will begin orbiting the planet on March 18, 2011.
The two spacecraft that have been sent to study Mercury are Mariner 10 and MESSENGER. Mariner 10 was the first to fly by Mercury in the 1970s, providing the first close-up images of the planet. MESSENGER, launched in 2004, became the first spacecraft to orbit Mercury, conducting extensive studies of its surface and environment from 2011 until its mission concluded in 2015.
Mariner 2 in 1962. The planet was Venus.
None of the Mariners actually landed on Venus. They were "fly-by" missions. Mariner 2 reached Venus in December 1962 and Mariner 5 in 1967. In 1973, Mariner 10 passed Venus and used the planet's gravity to alter its course and continued on to Mercury.
That statement is incorrect. Mariner 2 was the first spacecraft to successfully fly by and study another planet, Venus, not scan. It provided valuable data on Venus' atmosphere and surface temperature.
It did not land, but it did a successful fly by in 1965.
---- Mariner 10 was launched on November 3rd, 1973 at 05:45:00 Greenwich time. ----
Launched November 3rd, 1973, Mariner 10's third fly-by of the planet Mercury occurred on March 16th, 1975. While no longer in communication, it is considered to be still orbiting the Sun.See more information at the relatedlink listed below:
The first spacecraft to fly by Mars was Mariner 4 on Jul,14, 1965 (launched Nov,28,1964). Mariner 4 sent 21 photos.
Marnier 10 studied 2 planets, Venus and Mercury. It studied Venus on it's way to Mercury. Marnier 10 managed 3 fly-bys on Mercury before running out of maneuvering gas.
Mariner 4 returned close-range images of Mars in July 1965. It was the first spacecraft to successfully fly by and image another planet. The images provided valuable information about the Martian surface.
The spacecraft that took 22 close-up pictures of Mars in 1965 was called Mariner 4. It was the first spacecraft to successfully fly by Mars and capture close-up images of the planet's surface.
