The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space. [7] Voyager 1 is still active. In about 40,000 years the star Gliese 445 (AC +79 3888) and the Sun will fly past each other at a distance of 3.45 light-years, after being currently 17.6 light-years from each other, [ 8 ] with Voyager 1 coming Gliese 445 ...
Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites. The first artificial satellite launched into the Earth's orbit was the Soviet Union's Sputnik 1, on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of ...
As the number of man-made satellites in low-Earth orbit (LEO) continues to grow, astronomers are increasingly wary of their effects on terrestrial telescopes. ... a prototype satellite launched by ...
Brazil had yet to launch a satellite into orbit independently and its space program suffered three satellite launch failures, the latest being the explosion of a VLS-1 rocket on 22 August 2003 at the Alcântara Launch Centre, which resulted in 21 deaths. [10]
It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space. As of November 2017 it has a distance from the Sun of about 140 astronomical units (AU) [10] (21 billion kilometers, or 0.002 light years), and it will not be overtaken by any other current craft.
In 1957, the Soviet Union launched Sputnik 1, the first artificial orbital satellite. In 1961, Soviet Vostok 1 cosmonaut Yuri Gagarin became the first person to enter space and orbit the Earth, and in 1969 American Apollo 11 astronaut Neil Armstrong became the first person to set foot on the Moon.
