How many space probes are there?
There are five interstellar probes, all launched by the American space agency NASA: Voyager 1, Voyager 2, Pioneer 10, Pioneer 11 and New Horizons. As of 2019, Voyager 1, Voyager 2 and Pioneer 10 are the only probes to have actually reached interstellar space. The other two are on interstellar trajectories.
What planets have probes landed on?
All three of those stages have been carried out for the Moon, Venus, Mars, Jupiter, Saturn, a comet, and several asteroids. Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars.
What are some of the space probes used to explore the solar system?
Space probes have visited the Moon, asteroids, comets, and every planet in the solar system. There are three types of space probes: interplanetary, orbiters, and landers. The next generation of probes will bring back samples taken from celestial bodies.
What have the Voyagers discovered?
Voyager 1 is the first human-made object to venture into interstellar space. Voyager 1 discovered a thin ring around Jupiter and two new Jovian moons: Thebe and Metis. At Saturn, Voyager 1 found five new moons and a new ring called the G-ring.
How many probes has NASA launched?

When was the first space probe launched?
Sputnik 1 was the first probe to go into space. It was launched on Oct. 4, 1957, by the former Soviet Union. On Jan.
How many space probes have left the solar system?
As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018.
How far are the Voyager probes?
As of February 2018, Voyager is roughly 141 astronomical units (sun-Earth distances) from Earth. That’s roughly 13.2 billion miles, or 21.2 billion kilometers. You can look at its current distance on this NASA website.
How many space probes are orbiting Mars?
The following table is a list of Mars orbiters, consisting of space probes which were launched from Earth and are currently orbiting Mars. As of February 2021, there have been 18 spacecraft missions operating in Mars’ orbit, 8 of which are currently active.
What is the biggest space probe?
Currently the heaviest spacecraft is the International Space Station, nearly double Shuttle-Mir’s mass in orbit. It began assembly with a first launch in 1998, however it only attained its full weight in the 2020s, due to its modular nature and gradual additions.
