[UPDATED] Voyager 1 Is Back In Action! – Where Is Voyager 1 Now In 2024

2022 marks the 45th anniversary of NASA launching one of its most successful projects, the automatic spacecraft Voyager 1. The probe not only coped with the interplanetary mission brilliantly but also provided scientists with a large amount of valuable information about the heliosphere and interstellar space. Soon, spacecraft may fail, but even after that, it will continue to serve for the benefit of humanity, carrying out a diplomatic mission. And while NASA knows the Voyager 1 location and what is happening to the probe, the interest in Voyager persists. Let’s find out more about this spacecraft.

UPDATE 14 June: Voyager 1 Is Fully Operational, Sending Back Crucial Science Data From All Four Instruments

NASA’s Voyager 1 spacecraft has successfully resumed normal science operations, gathering crucial information about interstellar space after overcoming a technical issue that emerged in November 2023.

Issue Resolution Timeline:

  • April 2024: The Voyager team partially resolved the issue, enabling the spacecraft to start transmitting engineering data related to its health and status.
  • May 19, 2024: The mission team executed the next phase of the repair process, sending a command to Voyager 1 to begin returning science data. Two of the four science instruments immediately resumed normal operation, while the remaining two required additional adjustments. Now, all four instruments are fully operational and providing usable data.

UPDATE 22 APRIL: Voyager 1 Reconnects With Earth After Months of Silence

In a remarkable turn of events, NASA’s Voyager 1 spacecraft, the furthest human-made object from Earth, has reestablished contact with its home planet after months of silence. Launched in 1977, Voyager 1 has surpassed all expectations, venturing deeper into interstellar space than ever imagined.

After an extended period of communication blackout, Voyager 1 has finally “phoned home,” transmitting vital information about its onboard systems. While it’s not yet sending scientific data, the spacecraft is providing valuable insights into its health and operational status.

Voyager 1 Loses Contact: What causes the communication breakdown?

Voyager 1 has been suffering a communication malfunction since 14 November 2023. The legendary spacecraft hasn’t responded in 3 months. The mission team is increasingly worried about the possibility of the distant spacecraft being unable to recover.

The engineering team is actively working to resolve the issue. However, the challenges lie in both software limitations and the vast distance between Voyager 1 and its terrestrial controllers, making the resolution of the problem a complex undertaking.

Voyager 1 has started to experience a disruption in communication with its mission team on Earth due to a computer malfunction. On 14 November 2023, the NASA team noticed the issue. The spacecraft possesses three onboard computers. One of them collects data from scientific instruments and combines it with engineering data about Voyager 1’s current health status. This information is transmitted to Earth in binary code. However, the flight data system is currently stuck in a loop, sending a repetitive pattern of ones and zeroes. 

While Voyager 1 can receive and execute commands sent by the mission team, there is a problem with the telecommunications unit. It hinders the transmission of any scientific or engineering data from Voyager 1 back to Earth.

Moreover, the transmission of commands takes approximately 22.5 hours to reach the spacecraft. Also, there is an additional waiting period of 45 hours to receive a response from Voyager. This significant time delay poses a challenge for the team in managing and troubleshooting the current communication issue.

How much time will it take to resolve the problem?

Over a three-month period, the Voyager team attempted to restart the flight data system through commands. But as of now, they received no usable data. The further investigative process might extend over the course of several weeks.

Where did Voyager 1 go?

The primary mission was to fly around Saturn and Jupiter to study their satellite rings, magnetic fields, and weather. Voyager did an excellent job with this task, providing detailed images of the planets. At the time, no one could boast of such results, not even the USA’s main competitor, the USSR.

The second part of the mission was to search for and explore the boundaries of near-solar space and measure particles in the solar wind. Then, upon successful completion of the task, the probe had to move further and begin studying the interstellar medium. Skipping ahead, let’s say that the spacecraft exceeded all expectations, both in achieving the tasks set by the scientists and in the duration of work in deep space.

When did Voyager 1 launch?

Voyager 1 was launched on a Titan IIIE rocket from Cape Canaveral on September 5, 1977. Interestingly, there were two missions, Voyager 1 and 2. And the second Voyager was launched 16 days earlier than the first, on August 20.

It would be more logical to number the spacecraft in reverse, but the numbering order was defined by which spacecraft would be the first to meet Jupiter. So, Voyager 1 was supposed to reach Jupiter on March 5, 1979, and Voyager 2 — four months later, on July 9 of the same year.

How big is Voyager 1?

The spacecraft had a launch weight of 798 kg, a length of 2.5 m, and a payload mass of 86 kg. The body is a ten-facet prism, equipped with two antennas, a rod for electric generators, a rod with scientific instruments, and a separate rod for a magnetometer. The casing and equipment are supplemented by thermal insulation, heat shields, and plastic hoods.

Considering that the probe would operate far from the Sun, using solar panels would be pointless. Power is provided by three radioisotope thermoelectric generators operating on plutonium-238 oxide.

How fast is it travelling?

The speed of Voyager-1 at launch was 17 km/s, so it quickly reached Jupiter and began surveying the planet in January 1979. It approached Saturn in November 1980.

In August 2012, the probe became the first spacecraft to reach interstellar space. This fact was confirmed when the sensors recorded the influence of coronal mass ejections from the Sun in the form of a “tsunami wave”.

In 2017, the probe was recognized as the fastest spacecraft to leave our solar system. Even though the New Horizons probe, with a higher launch speed, was sent to Pluto in January 2006, Voyager 1 has beaten it in speed thanks to carefully calculated gravity manoeuvres. NASA claims that the spacecraft travels an average of 523 million kilometres a year.

How far away is it?

Voyager 1 is the most distant spacecraft ever launched by a man from Earth into space. We don’t really know exactly where the craft is now. According to NASA official data, as of February 17, 1998, the probe moved 10.4 billion km away from our planet.

In 2013, some media sources wrote that Voyager 1 will be leaving the solar system. However, this information was wrong. In fact, the probe only went beyond the solar wind. It will leave the solar system in about 30,000 years.

How far has Voyager 1 gone as of today?

Voyager 1 is currently zipping through space at around 38,000 mph (17 kilometers per second), according to NASA Jet Propulsion Laboratory. It is currently the farthest human-made object from Earth. As of February 2024, Voyager 1 is more than 24 billion km away from Earth. The distance between Voyager and the Earth differs in different periods of the year. This is because the speed of the planet in its orbit around the Sun exceeds the speed of the spacecraft moving away from it.

Will Voyager 1 ever leave the Milky Way?

The Milky Way is a vast galaxy with a diameter of about 100,000 light-years. With Voyager 1’s current speed, it would take tens of thousands of years to travel even a small fraction of the Milky Way’s distance.

As of now, Voyager 1 is not on a trajectory that will take it out of the Milky Way. Its path is primarily influenced by the Sun’s gravitational field, and its velocity is not sufficient to overcome the gravitational pull of the Milky Way’s stars and dark matter. So, it’s unlikely that Voyager 1 will ever leave the Milky Way in the foreseeable future.

Is Voyager 1 still transmitting?

Many people ask this reasonable question: Did we lose contact with Voyager 1 because it has been ploughing the expanses of space for almost half a century! The probe made its last image of the Earth in 1990. The picture was called A Pale Blue Dot. Voyager 1 was about 4 billion miles from Earth when it captured its portrait. Caught in the centre of scattered light rays (the result of shooting so close to the Sun), the Earth appears as a tiny dot of light, a crescent moon only 0.12 pixels in size. After that, the ship’s cameras were turned off in order to save energy for the operation of other equipment and continue with the interstellar space exploration.

Is Voyager 1 still active in 2023?

So is Voyager 1 still active? Yes! In 2021, the probe transmitted data on the detection of interstellar sounds and the measurement of the matter density in space. As long as Voyager 1 remains healthy, it’s likely the probe will continue its record-breaking missions for years to come.

Can Voyager 1 still take pictures?

Voyager 1 is equipped with several instruments, including cameras, that were used to capture images of planets and other celestial bodies during its mission within the solar system. However, as Voyager 1 has moved beyond the outer planets and into interstellar space, the distance from Earth and the limited power available to the spacecraft have significantly impacted its ability to take pictures. This has led to the shutdown of certain instruments and systems to conserve power for the primary communications and scientific instruments.

When will Voyager 1 die?

Voyager’s energy sources are constantly cooling and depleted, so today, they can no longer properly maintain the static temperature of the hardware. There are still four devices operating on board. However, when the power runs out, the probe will stop transmitting signals to the ground station.

NASA engineers claim that the spacecraft retains around 70% of its fuel is left on the ship, which should keep it operational until 2025. However, no one knows what other factors may affect the probe’s functionality in outer space.

How long will Voyager 1 battery last?

By 2025, the probe’s batteries are expected to be fully depleted. To conserve energy and prolong its operational life, NASA has been deactivating the spacecraft’s onboard systems. Currently, Voyager 1 retains four functioning instruments, all powered by Radioisotope Thermoelectric Generators (RITEGs), nuclear batteries that convert plutonium’s decay heat into electricity. However, due to a decline in power output over 44 years, NASA has shifted them into an economy mode. Engineers disabled the cosmic ray detector’s heater two years ago, a critical component for identifying the heliopause crossing.

Where will Voyager 1 be in 300 years?

Predicting Voyager 1’s exact location 300 years into the future is extremely challenging due to the complex interactions of gravitational forces and the dynamic nature of space. However, based on its current trajectory and velocity, it’s reasonable to assume that Voyager 1 will continue its journey through interstellar space within our Milky Way galaxy.

According to NASA, in about 300 years from now, Voyager 1 will enter the Oort Cloud, a spherical band far beyond Pluto’s orbit that’s full of billions of frozen comets. It will take another 30,000 years to reach the end of it.

Interesting facts about Voyager 1

Even after Voyager 1 cuts its cord with humanity it will continue to carry out an important diplomatic mission. The spacecraft has a gilded plate, called Voyager Golden Record, attached to its body. It contains a message for aliens in fifty different languages. The recording also carries music, sounds of nature, photographs of people, the Earth, cars, and aircraft. It carries the coordinates of the Earth so that another civilization can discover its location. In other words, Voyager 1 can still serve the benefit of mankind even outside of the Solar system.

How has Voyager 1 not hit anything?

Voyager 1’s remarkable avoidance of collisions during its journey through space can be attributed to a combination of factors. The vast expanse of the universe plays a significant role, as the immense distances between celestial bodies in the Milky Way mean that the likelihood of Voyager 1 encountering anything substantial is extraordinarily low. Additionally, the sparse distribution of matter in interstellar space further decreases the chances of collision. Meticulous trajectory planning by NASA’s experts has also been crucial. By utilizing intricate calculations and simulations, they’ve navigated the spacecraft through safe paths that circumvent known objects.

What happened to Voyager-1 in May 2022?

In May 2022, NASA recorded strange signals from Voyager-1. Mission specialists managed to find out that the device is still operating normally, but the readings of the articulation and attitude control system of the probe (AACS) do not reflect the real situation on board.

The AACS module is responsible for pointing the Voyager-1 antenna exactly at Earth, allowing the probe to send telemetry data. However, suddenly this data started to display incorrectly. Subsequent diagnostics revealed that, for some reason, AACS switched to another computer that stopped working several years ago, which distorted newly transmitted data. In August, NASA reported fixing this problem. A command was sent to AACS to switch to the correct computer, and it began to transmit correct telemetry data again. NASA suggests that AACS received an erroneous command from another computer (there are three of them on board Voyager-1), which may indicate that the main cause of the failure is somewhere else on the ship.

“We are happy that telemetry is back,” said the head of the mission, Suzanne Dodd. “Our team will perform a full read of the AACS memory and analyse its operation, which will help determine the exact cause that led to the distortion of the telemetry data.” At the same time, Dodd added that mission engineers do not see the incident as a long-term threat to Voyager-1 and are generally cautiously optimistic, although they still have to do more research.
