UNITED STATES: NASA’s Voyager 2 spacecraft, an intrepid explorer of the cosmos, is back in contact with Earth after a tense period of communication breakdown. The Jet Propulsion Laboratory (JPL) confirmed that they have successfully picked up a signal from Voyager 2, thanks to the agency’s Deep Space Network, which is designed to receive weak signals from distant spacecraft.
The spacecraft’s carrier signal, affectionately called its “heartbeat,” indicates that Voyager 2 is still active and broadcasting.
Engineers are now working to send a command to realign the spacecraft toward Earth. If successful, communication can be swiftly restored. However, if this attempt fails, they will have to wait until October, when the spacecraft’s onboard software will automatically reset its orientation.
The communication disruption occurred when planned commands unintentionally shifted Voyager 2’s antenna two degrees away from Earth, effectively cutting off contact with NASA’s Deep Space Network ground antennas. Currently, the spacecraft is approximately 12.4 billion miles (19.9 billion kilometres) away from Earth, drifting alone through interstellar space.
Despite the momentary glitch, there is hope for Voyager 2. The spacecraft is programmed to reset its orientation multiple times each year to ensure its antenna remains directed at Earth. The next scheduled reset is on October 15th, and it is anticipated that Voyager 2 will reestablish contact with its ground control after the reset.
Voyager 2 has a rich history of exploration, having been launched from Cape Canaveral, Florida, on August 20, 1977. On December 10, 2018, it became the second spacecraft to venture beyond the solar system and enter interstellar space, following its sister craft, Voyager 1, which achieved the same feat six years earlier and remains in contact with Earth.
Both Voyager 1 and Voyager 2 were designed with the mission of studying objects at the edge of the solar system. Voyager 2, in particular, has been instrumental in achieving several scientific breakthroughs. It is the only spacecraft to have conducted close-up studies of all four gas giants of the solar system: Jupiter, Saturn, Neptune, and Uranus.
Voyager 2 made history in January 1986 by becoming the first human-made object to fly past Uranus. During this encounter, it made astonishing discoveries, including the detection of ten new moons and two new rings around the ice giant.
In August 1989, Voyager 2 went on to become the first spacecraft to buzz past Neptune, where it found five moons and four rings. The spacecraft’s observations even led to the discovery of the immense cyclonic storm known as the Great Dark Spot, measuring a staggering 8,100 miles by 4,100 miles (13,036 km by 6,600 km) and boasting winds of up to 1,300 miles per hour (2,092 km/h).
The dedication of the Voyager team to preserving valuable data has been evident in their recent announcement. In April 2023, NASA decided to postpone a planned instrument shutdown for at least three more years, extending the gathering of deep space data until 2026.
As Voyager 2 continues its remarkable journey through the cosmos, scientists and space enthusiasts alike eagerly await discoveries and insights into the mysteries of our universe.
The revival of communication with Voyager 2 serves as a testament to human ingenuity and determination, showcasing the remarkable achievements of NASA’s interstellar explorers.
