for 45 years. Launched in 1977 to study Jupiter and Saturn. The probe is investigating truly unexplored territories. The Voyager Mission has been transmitting. information for longer than any other spacecraft and is now beyond the limits of the solar system; However, in the spring of 2022, the probe began sending

signal

s that baffled NASA engineers: They were unlike any previous messages from the spacecraft that had been traveling beyond the heliosphere for the longest time. More than 10 years ago, what caused the long-lift probe's unusual behavior and what it was trying to tell us about NASA's Voyager 1 spacecraft is a reminder of the romance of early spaceflight and the dreams of distant planets that captured the world in the 1960s and 1970s exploration of the solar system was one of the key tasks for the United States, discussion of the project to launch probes to neighboring planets began in the late 1960s and in 1972 engineers announced that a three-axis stabilized spacecraft that uses a guidance control system based on astronomical coordinates or a gyroscope to maintain the direction of high-gain antennas toward Earth.

The command computer subsystem or CCS provides sequencing and control functions. attitude and articulation control subsystem aacs controls the orientation of the spacecraft keeps the antenna pointed towards the Earth and controls the orientation Maneuvers Uplink communication Through the S-band command transmission rate of 16 bits per second, the Expenditure Three radioisotope thermoelectric generators or RTGs current power levels are approximately 249 watts. This system is one of the most complex ever developed for deep space, but it was a breakthrough for its time. The probes were named Voyager, after the new mission name invented in 1976. The spacecraft were launched. With a five-year exploration plan in charge of approaching Jupiter and Saturn, taking and transmitting images of the surroundings of these planets, since the return of Voyager 1 was not possible, NASA converted it into a space messenger aboard the probe. the gold record greetings in 55 languages ​​images of people and places on Earth and a collection of music from Beethoven to Chuxbury Johnny B Goode.

It is interesting that both Voyager Mission spacecraft were launched in the same year and that Voyager 1, which left Earth second, was supposed to reach its destination first according to its schedule. After a few months of travel, the spacecraft

sent

back the first space photographs of the Earth and the Moon, which had never before been seen in such a way. In 1979, the spacecraft approached Jupiter and showed scientists the first act of volcanoes beyond the Earth, on the moon IO, as well as Rush of two moons and threats in the ring system the spacecraft also observed. the first ray beyond Earth into Jupiter's atmosphere after reaching Saturn and its moon Titan Voyager 1's main discovery was the detection of three moons Atlas Prometheus and Pandora studying Titan revealed the first Earth-like atmosphere, rich in nitrogen, in which it was possible that liquid methane and ethane existed after the encounter with Saturn.

Voyager One headed upward from the plane of the planetary system to exit our solar system at a distance of about 4 billion miles. took its final images as part of its mission plan A portrait of the solar system This is the only existing series of photographs capturing Venus Earth Jupiter Saturn Uranus and Neptune all situated around the Sun Our visible home planet is a small pale blue dot in a A scattered ray of light led scientists to reflect on its fragility and vulnerability on this day the camera is a Voyager 1 was turned off to conserve the power of its computer would no longer approach any planet for exploration the subsequent history of the The mission was a stroke of luck and a testament to the reliability of the spacecraft system after the planned five-year mission had elapsed.

Voyager 1 continued to operate and transmit data continuing its journey into deep space in 1998, the Voyager 1 spacecraft surpassed the distance of the pioneer tent. and became the farthest artificial object from Earth in 2004 Voyager 1 became the first spacecraft to cross the boundary of the heliosphere and enter interstellar space through the termination shock where particles move slower than the speed of sound the solar wind made of plasma undergoes many changes here as a result of Heating and increasing pressure Interstellar space has much less density and temperature but has its own pressure. When it encounters this pressure, the heliosphere compresses, rotates and pushes particles so that the spacecraft crosses the heliopause and the final jump.

War accompanied by significant overloads and a shock wave. Unfortunately, ground-based antennas were unable to receive data from Voyager 1 during this process. After eight years, in 2012, the probe crossed the Helium Pause zone where the boundary between solar material and the particle scattering areas of other stars became clear. produces for the first time for a man. The manufactured object was in this part of space in April of the following year 2013 Voyager 1 recorded a sound from the space environment a unique sound caused by a mass ejection from the solar core the wave that reached the probe caused vibrations in its environment that had a new Non-heliospheric density was almost 40 times greater than previously measured.

The high-pitched tone of the signal became for NASA and humanity the final confirmation of the spacecraft's entry into a new space. In the following years of its journey, Voyager 1 encountered multiple solar tsunamis. times and transmitted data about them, this helped create new models of the solar wind and study the interaction between the heliosphere and the interstellar medium. In 2017, the mission team successfully ignited the spacecraft's backup engines to continue its journey. 37 years of waiting did not affect its reliability finally in 2021 Voyager 1 entered what NASA calls clean interstellar waters performing the first continuous measurement of the density of material in interstellar space changes in the environment can be judged by the change of frequency of the signals

sent

by the probe the higher the electron density, the louder the sound and vice versa, the mission team noticed an episodic decrease in the signal pitch that sometimes approached the atmospheric readings from the earth;

However, in early 2022, the space exploration veteran found itself in a confusing situation in space and began sending distorted telemetry data without signaling any alarms or malfunctions. It became a puzzle for the engineering team, the probe and its systems worked normally, receiving instructions from Earth, carrying them out by collecting and transmitting scientific measurements, however, the readings from the additive control and articulation system did not provide reliable information about the ship, the difficulties that it is. Precisely the aacs that maintains the orientation of Voyager 1 towards Earth, allowing communication to be maintained. A failure of the aacs could have caused the loss of the pro.

The aacs continued to function, providing a good signal level, but transmitted data on the position of the spacecraft as if is randomly generated, the task for the engineering team is complicated by the fact that the probe does not enter safe mode, a scenario in which only basic functions are performed and the hub is open to the diagnostic equipment and software in the data exchange step. He had to wait more than 20 hours into the life of the equipment, forcing NASA to approach the situation philosophically. The press service does not report how long the problem with the location of Voyager 1 has existed, but assures that engineers are ready to adapt.

Because of the new working conditions, such mystery is normal at this stage of the mission, explains Suzanne Dodd, project manager for Voyager 1 and Voyager 2 at NASA's Jet Propulsion Laboratory in Southern California. Both spacecraft are almost 45 years old, which is much older than the mission. The planner is also expected to be in interstellar space, a high-radiation environment that no spacecraft has flown in before, but I think if there is a way to solve this problem with AACS, our team will find that they brought the lost space traveler. again under control in August 2022 the culprit of sending incorrect data was also discovered the on-board computer that had malfunctioned many years ago was activated and connected to the message transmission chain that had not worked for a long time and was not was taken into account by the designated team as the cause of generating incorrect coordinates when the engineers suspected this was the problem, they made the decision with a low level of risk to give the aacs team the command to resume sending data to the computer was working properly, this helped telemetry transmission resume and Voyager 1 returned to its place in NASA's spacecraft motion scheme.

It is not yet known why aacs started sending location data to the wrong computer. Perhaps you received an erroneous command generated by another device on board. This is the case. There was a malfunction elsewhere in the spacecraft, the team continues to look for this main problem, but does not see it as a long-term threat to the health of Voyager 1. We are pleased to have Suzanne Dot do a full read of the memory AECS. And she looks at everything that is in debt, this will help us diagnose the problem that caused the telemetry errors and conduct further investigations.

Today Voyager 1 continues its journey and sends new data about interstellar space. NASA predicts that the spacecraft's engines will last at least until 2025. Each spacecraft produces about 4 watts less electrical power annually, limiting the number of systems the generator can support in an effort to reduce the load. Mission engineers have locked down the heaters, prioritizing space exploration. no scientific instruments have been turned off due to reduced power. As the probe continues to collect data using its cosmic ray instrument, a plasma instrument, a magnetometer, and a low-energy charged particle instrument, the Voyager team is working to ensure the spacecraft continues to collect unique scientific data for the longest time. possible time traveling many more kilometers before falling asleep.
