Also, how many planets have we visited? More than 250 robotic spacecraft—and 24 humans—have ventured into space since we first began exploring beyond Earth's atmosphere in 1958. This section focuses on U.S. missions with science goals to study planets, moons, asteroids and comets beyond Earth orbit.

On December 15, 1970 an unmanned Soviet spacecraft, Venera 7, became the first spacecraft to land on another planet. It measured the temperature of the atmosphere on Venus. In 1972, Venera 8 gathered atmospheric and surface data for 50 minutes after landing.What's NASA's latest mission called?
NASA's latest mission to Mars -- a mission that will receive a new name before launch -- will be the latest rover to head to the Red Planet, but it's not going alone. To aid it in its exploration, it's carrying the first helicopter that will fly on another planet.Can we land on Jupiter?
Surface. As a gas giant, Jupiter doesn't have a true surface. While a spacecraft would have nowhere to land on Jupiter, it wouldn't be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet crush, melt and vaporize spacecraft trying to fly into the planet.What is Jupiter's Great Red Spot?
The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anticyclonic storm, the largest in the Solar System, 22 degrees south of Jupiter's equator. It has been continuously observed since 1830.What is the farthest planet we have landed on?
The farthest in space that humans have gone is the moon, most recently during the Apollo 17 mission in December 1972. The farthest that any object made by humans has gone is slightly outside of our own solar system (farther out than any of the planets, that is, but still within the reach of the sun's influence).Has any country been to Mars?
