The spacecraft recorded important heliophysics data in early August 1972 by registering a solar shock wave when it was at a distance of 2.2 AU (330 million km; 200 million mi). [38] On July 15, 1972, Pioneer 10 was the first spacecraft to enter the asteroid belt, [4] located between the orbits of Mars and Jupiter. The project planners expected ...
The first spacecraft to explore Jupiter was Pioneer 10, which flew past the planet in December 1973, followed by Pioneer 11 twelve months later. Pioneer 10 obtained the first close-up images of Jupiter and its Galilean moons; the spacecraft studied the planet's atmosphere, detected its magnetic field, observed its radiation belts and determined ...
The first spacecraft to visit an asteroid was Pioneer 10, which flew past an unnamed asteroid on 2 August 1972; a distant incidental encounter while the probe was en route to Jupiter. The first dedicated mission was NEAR Shoemaker , which was launched in February 1996, and entered orbit around 433 Eros in February 2000, having first flown past ...
The Pioneer programs were two series of United States lunar and planetary space probes.The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus.
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
The spacecraft has embarked on a 1.8 billion-mile journey toward Europa, a moon that scientists believe could mark humanity’s first recorded encounter with alien lifeforms in outer space.
A recurring problem. It’s not the first time Voyager 1 has needed to switch over to another set of thrusters in recent decades. Fortunately, the spacecraft has three sets of thrusters: two sets ...
By BANU IBRAHIM Meet Philae, the European Space Agency's probe that just woke up from seven months in hibernation. Philae is the first spacecraft ever to land on a comet. Although it reached the ...
