A total of 11,000 workyears was devoted to the Voyager project through the Neptune encounter. This is equivalent to one-third the amount of effort estimated to complete the great pyramid at Giza to King Cheops. 

Conclusion

For concluding in this theme about :VOYAGER 1 AND 2 .

we hope that you understand this great and wonderful topic that is very well connected with space and in addition to some of the planets of the solar system, and also know you who purchased a conocimento emerged about how this great discovery that is widely used in space outside :)

and end this kind of adventures are what makes me believe that man can greatly advance knowledge of the universe, if we devote the effort and resources needed to develop this type of space missions and forget about the problems we consume everyday here on earth: religious conflicts, arms race, national selfishness, intolerance, racism, lack of culture final.

Opinions about Voyager 1 and 2

John Casani
Voyager Project Manager 1975-1977

"Voyager opened our eyes to what was out there in the solar system and provides us a compelling argument for going back with missions like Galileo, Cassini and other missions that will follow"


 
Chris P. Jones
Voyager Fault Protection Engineer (1973-1975)
Voyager Flight S/W System Engineer (1975-1977)
Voyager Spacecraft Team Chief (1978-1981)

"We began the MJS77 Project in 1973 with a stripped down version of the high-tech Outer Planets Grand Tour mission. From those humble beginnings, the two intrepid explorers named Voyager have generated a national pride and identity. Today they're recognizable by all age groups, and no wonder. One can find them referenced in school science texts, in a prominent role in an old Star Trek movie, and even in an image subtly placed on a Moody Blues album
cover."

 
Dr. Edward C. Stone
Voyager Project Scientist (1972-Present)

"The Voyager mission has opened up our solar system in a way not possible before the Space Age." "It revealed our neighbors in the outer solar system and showed us how much there is to learn and how diverse the bodies are that share the solar system with our own planet Earth."

ScienceShot: Has Voyager 1 Left the Solar System?

NASA


More than 35 years after its launch and almost 33 years since it whizzed near Saturn, the Voyager 1 spacecraft may have officially left the solar system. On 25 August last year, when the craft was more than 18 billion kilometers from the sun, sensors noted a steep drop-off in the numbers of so-called anomalous cosmic rays, the charged particles that often become trapped in the magnetically turbulent region that separates the solar system from interstellar space. At the same time, the sensor detected a dramatic rise in the numbers of intense galactic cosmic rays that originate far beyond our solar system—the largest such jump since the craft was launched, the researchers report online and in a forthcoming issue of Geophysical Research Letters. Cosmic ray intensities had been fluctuating for several weeks prior to 25 August, a sign that the Voyager craft may have been moving through the turbulent boundary of the solar system—or that the boundary may have been shifting back and forth in space, sweeping across the craft as it did so, due to variations in solar activity. But in the past 6 months, cosmic ray levels have stabilized. Although scientists may debate whether Voyager 1 has truly left the solar system, it's clear that the craft has entered a region of space totally unlike that it has traversed since it left Earth.

Update 21 March: Yesterday afternoon, NASA's Jet Propulsion Laboratory released a statement that read, in part, "It is the consensus of the Voyager science team that Voyager 1 has not yet left the solar system or reached interstellar space. ... A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change of direction has not yet been observed.

Voyager Golden Records

The Voyager Golden Records are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. The Voyager spacecraft is not heading towards any particular star, but Voyager 1 will be within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years.[1]

More about Voyager 2

VOYAGER 2


The space probe Voyager 2 was launched on August 20, 1977 from Cape Canaveral on a Titan-Centaur rocket. It is identical to its sister probe, Voyager 1. Both probes were originally conceived as part of the names Mariner Mariner 11 and Mariner 12, respectively.


Unlike its predecessor, the Voyager 2 took a different path in its encounter with Saturn, sacrificing proximity to Titan, but taking a greater gravitational pull on their journey to Uranus and Neptune. The probe reached its closer proximity to these planets in the years 1986 and 1989, respectively.


Although many of his instruments are out of service, inspecting continues around the Solar System. At the speed of 14.8 km / s, take about 193,000 years to reach the star Ross 248, which pass at a distance of 1.7 light years.


Located at a distance of 100 AU (about 14 light-hours) from Earth in November 2012,1 has become one of the most distant objects that created man.


The December 10, 2007 discovered that the solar system has a spherical shape, but oval, due to the interstellar magnetic field of deep space.


The probe Voyager 2 was launched to take advantage of the positions of Jupiter and Saturn, as well as the then recent gravitational boost technique. In this way, the same mission could visit several planets with saving this implied.


Voyager 2 was launched on August 20, 1977 from the Kennedy Space Center NASA’s Cape Canaveral aboard a Titan IIIE rocket.




The ground staff was so focused on a problem occurred during the launch of its twin, Voyager 1, which forgot to send Voyager 2 activation code its high-gain antenna. Luckily, the staff was able to contact the probe through the low-gain antenna and activate it.








VOYAGER2

HISTORY OF VOYAGER 1 AND 2

HISTORY OF VOYAGER 1 AND 2


Voyager 1 is escaping the solar system at a speed of about 3.6 AU per year, 35 degrees out of the ecliptic plane to the north, in the general direction of the Solar Apex (the direction of the Sun’s motion relative to nearby stars). Voyager 2 is also escaping the solar system at a speed of about 3.3 AU per year, 48 degrees out of the ecliptic plane to the south.


Passage through the termination shock ended the termination shock phase and began the heliosheath exploration phase. Voyager 1 crossed the termination shock at 94 AU in December 2004 and Voyager 2 crossed at 84 AU in August 2007. Since passage through the termination shock, the spacecraft has been operating in the heliosheath environment which is still dominated by the Sun’s magnetic field and particles contained in the solar wind. The heliosheath exploration phase ends with passage through the heliopause which is the outer extent of the Sun’s magnetic field and solar wind. The thickness of the heliosheath is uncertain and could be tens of AU thick taking several years to traverse. Passage through the heliopause begins the interstellar exploration phase with the spacecraft operating in an interstellar wind dominated environment. This interstellar exploration is the ultimate goal of the Voyager Interstellar Mission.


Both Voyagers are headed towards the outer boundary of the solar system in search of the heliopause, the region where the Sun’s influence wanes and the beginning of interstellar space can be sensed. The heliopause has never been reached by any spacecraft; the Voyagers may be the first to pass through this region, which is thought to exist somewhere from 8 to 14 billion miles from the Sun. This is where the million-mile-per-hour solar winds slows to about 250,000 miles per hour—the first indication that the wind is nearing the heliopause. The Voyagers should cross the heliopause 10 to 20 years after reaching the termination shock. The Voyagers have enough electrical power and thruster fuel to operate at least until 2020. By that time, Voyager 1 will be 12.4 billion miles (19.9 billion KM) from the Sun and Voyager 2 will be 10.5 billion miles (16.9 billion KM) away. Eventually, the Voyagers will pass other stars. In about 40,000 years, Voyager 1 will drift within 1.6 light-years (9.3 trillion miles) of AC+79 3888, a star in the constellation of Camelopardalis which is heading toward the constellation Ophiuchus. In about 40,000 years, Voyager 2 will pass 1.7 light-years (9.7 trillion miles) from the star Ross 248 and in about 296,000 years, it will pass 4.3 light-years (25 trillion miles) from Sirius, the brightest star in the sky . The Voyagers are destined—perhaps eternally—to wander the Milky Way.

Introduction to Voyager 1 and 2

MISSION OBJECTIVE


The mission objective of the Voyager Interstellar Mission (VIM) is to extend the NASA exploration of the solar system beyond the neighborhood of the outer planets to the outer limits of the Sun’s sphere of influence, and possibly beyond. This extended mission is continuing to characterize the outer solar system environment and search for the heliopause boundary, the outer limits of the Sun’s magnetic field and outward flow of the solar wind. Penetration of the heliopause boundary between the solar wind and the interstellar medium will allow measurements to be made of the interstellar fields, particles and waves unaffected by the solar wind.
MISSION CHARACTERISTIC


The VIM is an extension of the Voyager primary mission that was completed in 1989 with the close flyby of Neptune by the Voyager 2 spacecraft. Neptune was the final outer planet visited by a Voyager spacecraft. Voyager 1 completed its planned close flybys of the Jupiter and Saturn planetary systems while Voyager 2, in addition to its own close flybys of Jupiter and Saturn, completed close flybys of the remaining two gas giants, Uranus and Neptune




At the start of the VIM, the two Voyager spacecraft had been in flight for over 12 years having been launched in August (Voyager 2) and September (Voyager 1), 1977. Voyager 1 was at a distance of approximately 40 AU (Astronomical Unit - mean distance of Earth from the Sun, 150 million kilometers) from the Sun, and Voyager 2 was at a distance of approximately 31 AU.
