Voyager 2 engineer is working to restore normal operation, Voyager 2 spacecraft engineers from NASA are working to return the mission to normal operating conditions after one of the spacecraft’s autonomous damage control procedures has been activated.
Both Voyager 1 and Voyager 2 have several damage protection procedures programmed to allow the spacecraft to automatically take protective measures in the event of a dangerous situation.
At NASA’s Jet Propulsion Laboratory in Pasadena, California, engineers are still communicating with spacecraft and receiving telemetry.
Voyager 1 and Voyager 2 were launched in 1977 and are located in interstellar space. They are the most distant objects in the solar system. On Saturday, January 25, Voyager 2 did not carry out planned maneuvers in which the spacecraft rotated 360 degrees to calibrate the magnetic field on the ship.
Spacecraft telemetry analysis shows that the two systems consume relatively high power and work simultaneously because of an unexplained delay in the execution of unintentional maneuvers on board. now the Voyager 2 engineer is working to restore normal operation.
This causes the spacecraft to exceed the available power supply.
Troubleshooter is designed to automatically manage such events and appears to have disabled the Voyager 2 scientific tool to compensate for the power outage. On January 28, Voyager’s engineers succeeded in shutting down one of the high-performance systems and reactivating scientific tools, but did not continue to request data.
The team is currently reviewing the condition of other spacecraft and is trying to return it to normal conditions.
The energy for Voyager comes from the Radioisotope Thermoelectric Generator (RTG), which converts heat from the decay of radioactive material into electricity to power a spacecraft. Due to natural damage to the material in the RTG, the Voyager 2 power budget is reduced by around 4 watts per year.
Last year, engineers shut down the Voyager 2 subsystem space heater to compensate for this loss of performance, and the device continued to work. Nasa Voyager 2 engineer is working to restore normal operation.
In addition to managing the energy of each Voyager, mission operators must also control the temperature of certain spacecraft systems. For example, if the spacecraft’s fuel lines freeze and break up, Voyager can no longer aim the antenna at earth to send data and take orders.
The temperature of the spacecraft is maintained either by using heaters or by using excess heat from instruments and other systems on board.
It took several days for the team to assess the current situation, mainly because of the distance of Voyager 2 from Earth – around 18.5 billion kilometers. Communication transmitted at the speed of light takes about 17 hours to reach the spacecraft and another 17 hours to respond to its return to Earth from the spacecraft.
As a result, mission engineers had to wait about 34 hours to find out if their orders had the desired effect on the spacecraft.
