How many probes have we sent to Mercury?
two probes
Only two probes have ever traveled to the planet. The first was Mariner 10, a spacecraft meant to study both Venus and Mercury. It flew by Mercury three times in 1974 and 1975. Then, in 2004, NASA launched the MESSENGER spacecraft, which successfully inserted itself into Mercury’s orbit in 2011.
Are there any probes around Mercury?
The exploration of Mercury has a minor role in the space interests of the world. It is the least explored inner planet. As of 2015, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury. MESSENGER was the first probe to orbit Mercury.
Which space probe flew past Mercury?

Can we send a rover to Mercury?
Mercury is actually very difficult to reach directly due to its location deep inside the Sun’s gravitational well. Gravitational assists from Venus and Earth can help but at the cost of an extended mission duration. In addition landing on Mercury has to be propulsive as there is no significant atmosphere to brake into.
How many probes have we sent to Venus?
There have been 42 space missions to the planet Venus. Missions to Venus constitute part of the exploration of Venus.
Does Mercury have satellites or robots?
Mercury now has an artificial satellite, for the first time ever.
Does Mercury rotate on its axis?
Mercury rotates slowly. One rotation takes nearly 59 Earth days to complete. Mercury does not tilt on its axis, therefore the Sun would constantly be situated on the horizon at the poles). The image above shows how Mercury completes three rotations around the Sun for every two orbits.
When did Mariner 10 reach 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.
Does Mercury have any manmade satellites?
What are Mercury’s satellites?
The planet has no known natural satellites. Two spacecraft have visited Mercury: Mariner 10 flew by in 1974 and 1975; and MESSENGER, launched in 2004, orbited Mercury over 4,000 times in four years before exhausting its fuel and crashing into the planet’s surface on April 30, 2015.
