What did the Mariner 10 spacecraft discover about Mercury?

Scientists believed that Mercury’s magnetic field came from within the planet rather than being generated through the planet’s interaction with the solar wind. Mariner 10 detected a faint helium atmosphere around the solar system’s innermost planet.

What did we learn from Mariner 10?

Discoveries. During its flyby of Venus, Mariner 10 discovered evidence of rotating clouds and a very weak magnetic field. Using a near-ultraviolet filter, it photographed Venus’s chevron clouds and performed other atmospheric studies. The spacecraft flew past Mercury three times.

What did the probes find on Mercury?

The probe detected Mercury’s magnetic field, which is very similar to Earth’s. This was a surprise to scientists, because Mercury spins so slowly on its axis. Secondly, visual data was provided, which showed the high number of craters on the surface of the planet.

When was Mariner 10 launched and what did this spacecraft do?

Brief Description. Mariner 10 was the first spacecraft to use the gravitational pull of one planet to reach another and the first probe to visit two planets. Launched November 3, 1973, it reached Venus on February 5, 1974. Using gravity assist, it went on to fly by Mercury.

What is Mariner 10 and how is it connected to Mercury?

Mariner 10 was the seventh successful launch in the Mariner series and the first spacecraft to visit Mercury. 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.

When was Mercury discovered?

Timocharis made the first recorded observation of Mercury in 265 BC. Other early astronomers that studied Mercury include Zupus (1639), who studied the planet’s orbit.

When did Mariner 10 visit Mercury?

Sept. 21, 1974
Mariner 10 flew by Mercury once more on at 20:59 UT Sept. 21, 1974, at a range of about 29,869 miles (48,069 kilometers), adding imagery of the southern polar region. The spacecraft used solar pressure on its solar panels and high-gain antenna for attitude control.

When was the Mariner 10 launched?

Which spacecraft is on its way to Mercury now?

The BepiColombo spacecraft
The BepiColombo spacecraft is on its way to Mercury! Europe’s first mission to Mercury, which is the smallest and least explored planet in our solar system, will arrive at its destination later today, but it won’t be a very long visit!

How close did Mariner 10 get to Mercury?

By the time of humanity’s first close encounter with the Solar System’s first planet, when the Mariner 10 space probe passed 700 km from Mercury on 29 March 1974, missions to our planetary neighbours had been underway for more than a decade.
