Voyager 1 is presently the farthest spacecraft from Earth at around 15 billion miles (24 billion kilometers) away, while its twin Voyager 2 has traveled greater than 12 billion miles (20 billion kilometers) from our planet. Both remain in interstellar space and are the only spacecraft ever before to run beyond the heliosphere, the sunlight’s bubble of electromagnetic fields and fragments that expands well past the orbit of Pluto.
Originally prepared to have a duration of 5 years, the Voyager probes have surpassed all assumptions by becoming the spacecraft that have operated for the lengthiest amount of time in background. These expanded life times have actually enabled the probes to collect additional knowledge about our solar system and beyond, also after successfully completing their preliminary purposes of exploring Jupiter, Saturn, Uranus, and Neptune lots of decades earlier.
Engineers are presently trying to fix the issue as the aging spacecraft checks out undiscovered cosmic region along the external reaches of the planetary system.
A computer malfunction on NASA’s Voyager 1 space probe has led to a minor disturbance in communication between the 46-year-old spacecraft and its group of researchers in the world.
Voyager 1 has three onboard computer systems, consisting of a flight information system that collects information from the spacecraft’s science instruments and packages it with engineering data that shows the present health and wellness status of Voyager 1. Mission control on Earth receives that data in binary code, or a collection of ones and nos.
Yet Voyager 1’s trip data system now appears to be stuck on auto-repeat, in a scenario evocative the film “Groundhog Day.”
A Glitch in Voyager 1
According to Calla Cofield, a media relationships professional at NASA’s Jet Propulsion Laboratory in Pasadena, California, that oversees the mission, NASA designers are currently servicing obtaining additional details concerning the root cause of the problem. It is just after gathering this information that they will decide on the subsequent actions that may be necessary to repair it. The whole procedure could potentially span several weeks.
The Voyager team is taking a mindful approach by thoroughly taking a look at all feasible effects before transferring added directions to the spacecraft. This ensures that the spacecraft’s features aren’t endangered in an unexpected manner.
As both Voyager probes experience brand-new tests, mission staff member have only the initial guidebooks composed years ago to seek advice from, and those couldn’t represent the obstacles the spacecraft are encountering as they age.
On November 14, the objective group observed an abnormality in the flight information system’s telecoms device, which was sending a recurring series of ones and absolutely nos, recommending that it was embeded a loop.
While the spacecraft can still receive and carry out commands transferred from the mission team, a trouble keeping that telecoms unit means no science or engineering data from Voyager 1 is being gone back to Earth.
The Voyager team sent commands over the weekend break for the spacecraft to reboot the flight data system, but no useful data has actually returned yet, according to NASA.
The range in between Earth and Voyager 1 is so substantial that it takes virtually a complete day for instructions sent from our earth to reach the spacecraft, and afterwards one more 45 hours to receive a reply.
The last time Voyager 1 experienced a comparable, but not the same, concern with the flight data system remained in 1981, and the current trouble does not appear to be linked to other problems the spacecraft has experienced in recent times, Cofield claimed.
Sustaining the durability of the Voyager spacecraft
According to Suzanne Dodd, the project supervisor of Voyager, the team has been slowly shutting down the tools on these senior Voyager probes to conserve power and extend their missions as they remain to check out deep space.
The mission team has actually been imaginative with its techniques for extending the power supply on both spacecraft in the last few years to allow their record-breaking objectives to continue.
“The Voyagers are performing much, much past their prime objectives and longer than any other spacecraft in background,” Cofield said. “So, while the design group is working hard to keep them active, we also fully anticipate problems to arise.”
According to Cofield, although the team needs to renew the consistent flow of information sent by Voyager 1, the key relevance of the mission is its extensive period. For instance, scientists want observing the alterations in bits and electromagnetic fields as the probes relocate further from the heliosphere. Nevertheless, the data collected will certainly be insufficient if Voyager 1 can not supply info while it proceeds.
The two spacecraft have met with unanticipated issues and interruptions during their journey, consisting of a seven-month interval in 2020 when Voyager 2 was not able to get in touch with Earth. In August, the mission team employed a hardly ever made use of “squeal” approach to reestablish contact with Voyager 2 after a wayward command accidentally aimed the spacecraft’s antenna in the wrong direction.
