WHAT ARE THE VOYAGERS?
The Voyagers are a pair of unmanned US space probes, launched to explore outer planets.
Voyager 1 was launched on the 5th of September 1977. It flew past Jupiter in March 1979 and Saturn in November 1980, then continued on a curved path to take it out of the Solar System altogether.
Voyager 2 travels more slowly. Although it was launched 2 weeks earlier than Voyager 1 it did not reach Jupiter until July 1979 and Saturn until August 1981.
The Voyagers used the slingshot effect of Jupiter’s gravity to hurl them towards Saturn.
While Voyager 1 headed out of the Solar System, Voyager 2 flew past Uranus in January 1986.
Voyager 2 also passed Neptune on 25 August 1989. It took closeup photographs of Uranus and Neptune.
The Voyagers revealed volcanoes on Io, one of the Jupiter’s Galilean moons.
Voyager 2 found ten moons around Uranus.
Six moons and five rings around Neptune were also discovered by Voyager 2.
HOW WAS SCIENTIFIC KNOWLEDGE APPLIED TO THE SPACE MISSION?
Voyager 1 and 2 helped a lot of scientists in terms to investigate about other planets. How a human couldn’t go to such planet like Neptune to take a photo, Voyager 1 and 2 were the perfect candidates for the job. The time they were launched, Voyager one and two were one of the best missions by NASA.
What were they trying to investigate?
Voyager 1 and 2 were sent to space to investigate Jupiter and Saturn. After exploring these 2 planets, the mission was extended to explore new planets out of our solar system. No human being had ever attempted a journey like that before.
This mission took more than thousands of photos of Jupiter and its moons. That was when humans saw for the first time important parts of that planet.
WHAT ADVANTAGES AND DISADVANTAGES
Unmanned space probes can go where astronauts cannot. These include missions that get close enough to the sun to where heat and radiation levels would kill a human. And a long-term unmanned voyage could go farther than a craft that had to carry food to sustain life. Unmanned craft allow for such missions as Voyager 1 and 2, which not only visited some of the outermost bodies in the solar system but continue to journey out into space and send data back to Earth. Indeed, Voyager 1 is now traveling outside the solar system, in interstellar space. Sending human-made objects into space is always very expensive. However, unmanned space probes cost less than manned missions because the design of the vehicles does not have to accommodate and sustain human life and this allows the space agency perform more missions with a limited budget. While space probes can undertake missions that would preclude human involvement, they are not perfect. Whereas humans can adapt to changing situations and repair malfunctions, probes can only execute their programming.
While manned missions are more limited from a scientific standpoint, they are far more effective at capturing the public opinion necessary for funding space exploration than the unmanned probes.
Voyager 2 is taking the measure of its exotic surroundings once again. On Jan. 25, the venerable probe, which has been exploring interstellar space since November 2018, failed to execute a spin maneuver as intended. As a result, two onboard systems remained on longer than planned, sucking up so much energy that Voyager 2 automatically shut off its science instruments. Mission team members expressed confidence at the time that they could troubleshoot the problem, and their confidence has been borne out: Voyager 2's science gear is back up and running, NASA announced Wednesday (Feb. 5).
Conclusion
Voyager 1 was launched on the 5th of September 1977. It flew past Jupiter in March 1979 and Saturn in November 1980, then continued on a curved path to take it out of the Solar System altogether.
Voyager 2 travels more slowly. Although it was launched to weeks earlier than Voyager 1 it did not reach Jupiter until July 1979 and Saturn until August 1981. The voyager 2 has flown 10 billion km and is heading out of the solar system after passing close to Jupiter (1979) , Saturn (1981), Uranus (1986) and Neptune (1989). This mission took more than thousands of photos of Jupiter and it's moons. The Voyagers found 22 new satelites. 3 at Jupiter, 3 at Saturn, 10 at Uranus and 6 at Neptune , revealed volcanoes on Io, one of the Jupiter’s Galilean moons, the only solar system body other than the Earth to have this confired.among other important discoveries. The Voyager mission not only transformed our knowledge of Jupiter, Saturn and their dozens of moons, it also gave us our first close- and up look at the strange wonderous planets Uranus and Neptune. These are some of the reasons why Voyager will be remembered as one of the greatest achievments in exploration of Space.
