Engineers have identified a corrupted memory issue in Voyager 1’s onboard computer, hindering data transmission to Earth.’s Voyager 1 has been causing the spacecraft to send unreadable science and engineering data to Earth since last November. Called the flight data subsystem , the computer is responsible for packaging the probe’s science and engineering data before the telemetry modulation unit and radio transmitter send the data to Earth.
The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn’t working. Engineers can’t determine with certainty what caused the issue. Two possibilities are that the chip could have been hit by an energetic particle from space or that it simply may have worn out after 46 years.
Although it may take weeks or months, engineers are optimistic they can find a way for the FDS to operate normally without the unusable memory hardware, which would enable Voyager 1 to begin returning science and engineering data again.. They are both exploring interstellar space, outside the bubble of particles and magnetic fields created by the Sun, called the heliosphere. Voyager 2 continues to operate normally.SciTechDaily: Home of the best science and technology news since 1998.

With a new experimental technique, engineers probe the mechanisms of landslides and earthquakesResearchers developed a method for 3D experiments that can reveal how forces are transmitted through granular materials, and how the shapes of the grains can dramatically change the outcomes. This could lead to better ways of understanding how landslides are triggered, and how to control the flow of granular materials in industrial processes.
