Space. traveling 1, this nasa: This article explores the topic in depth.
Consequently,
Space. Similarly, traveling 1. Furthermore, this nasa:
When she left the earth, Jimmy Carter had just arrived at the White House and Star Wars had not yet been released on French screens. Similarly, Way in 1977, would the Voyager 1 probe recognize the planet she left behind? Furthermore, What does it matter since it has already reached the suburbs of the solar system. Furthermore, and now rushes towards the constellation of the giraffe. Therefore, In ten days. Consequently, it will be 25 billion kilometers from the earth – a barely imaginable distance, corresponding to more than 160 times the distance between the sun and the earth. In addition, Since 2012. For example, the American probe has left the heliosphere, this plasma bubble which protects the solar system from cosmic radiation, and now crosses interstellar space.
Originally. For example, its mission was not to last only five years: the time space. traveling 1, this nasa of a simple one to Jupiter and Saturn, thanks to an alignment of the planets as there is less than one per century. Similarly, In 1979, travel 1 pierced part of the secrets of Jupiter. Meanwhile, Transmitted by means of its parabolic antenna. Meanwhile, its shots reveal with unprecedented precision the cloudy bands of the giant planet, as well as rings hitherto passed unnoticed.
Volcanoes on IO – Space. traveling 1, this nasa
The probe also detects. Therefore, for the first time, a volcanic activity on another body than the earth, in this case on IO, one of four Galilean satellites. In November 1980, traveling 1 SATURNE FURENDED and bordered on his Moon Titan, whose atmosphere rich in methane intrigues scientists from NASA.
His flirt with Titan catapults the probe outside the ecliptic plan. while his twin continues his journey to the borders of the solar system. Launched three weeks earlier. traveling 2 will reach Uranus in 1986 space. traveling 1, this nasa and Neptune in 1989, discovering in passing around twenty moons and the Neptune rings system. To date, it is the only probe to have ventured near the two ice giants. In 1990, traveling 1 also took a last symbolic photo of the earth: a pale blue point lost in immensity.
Troubleshooting at a very long distance
This cascade of scientific exploits follows a series of technical miracles. Once the objectives are accomplished. while the two probes spin towards the borders of the solar system, NASA decides to continue the Voyager program. To save energy, certain instruments are unplugged, starting with the cameras, unnecessary while the probes sink into darkness. Others show signs of degradation. In 2017. to correct the orientation of Voyager 1, propellants that had not worked since 1980 are reinforced – a test that puts the nerves of NASA engineers to the test: the signal takes more than 19 hours space. traveling 1, this nasa to reach the probe, as much for the return. At the end of 2023, traveling 1 started to tell anything. Engineers diagnose memory corruption that an update of its computer code allows you to bypass. Last May, another propeller for stopping for over 20 years has been reinforced.
21 billion kilometers from the earth, traveling 2 is subject to the same ravages of time. In August 2023, NASA thought it has lost contact, but the probe automatically realized a few days later.
A battery that is slowly exhausted
Incredible, traveling 1 is not eternal. The probe still has 20 % of its hydrazine reserves. fuel that it uses sparingly to realign with the earth: enough to hold a good ten years. But its engines are largely obstructed by deposits. On the electric side. the Plutonium battery of the probe has lost more than half of its 470 W of initial power. It space. traveling 1, this nasa is necessary to juggle between the instruments. heating necessary for the operation of the engines, with always the fear that one or the other does not restart.
But ironically. it is the election of a new American president who could be right for the dean of current programs. At the end of June. NASA has already closed the accounts on the social networks of around twenty missions, including Voyager. And traveling could be part of the programs sacrificed by the American agency. on the altar of budget cuts and the war with science decreed by Donald Trump.
The end of the trip for the probe? Not necessarily. In a few centuries, travel 1 will cross the Oort cloud which marks the border of the solar system. And in 40. 000 years, cold and extinct for a long time, it will arrive near the Gliese 445 star, carrier of the famous golden disc space. traveling 1, this nasa for a hypothetical extraterrestrial civilization. There are anatomical boards, photographs of the earth and its inhabitants, recordings of Mozart, Chuck Berry or bird songs. Released too late, Star Wars does not appear there. Donald Trump either.
