The only human-made object outside our solar system is still alive and kickin
The last time Voyager’s 1 trajectory correction maneuver thrusters last fired, Ronald Reagan had just been elected president.
The thrusters had officially served their purpose, after 30 years, about a decade into the journey out to the edge of out solar system. The trajectory correction maneuver (TCM) thrusters fired up to correct the object’s course, to allow the spacecraft to explore Jupiter, Saturn, and several moons orbiting them.
The last course correction for Saturn was on November 8,1980, after that the (TCM) went silent.
NASA fired them up again last week, and after 37 years the thrusters worked, They can extend the mission by several years.
Voyager 1 is the fastest spacecraft we’ve got, traveling at around 11 miles per second.
and it’s the farthest, Voyager 2, the second spacecraft is 11 billion miles away from the Sun.
Voyager 1 is the first human-made object to enter Interstellar space, and it’s 13 billion miles away from the Sun.
Even from a great distance, the spacecraft can still send messages back to Earth. That’s when the thrusters come in handy. Only a set of thrusters has served to set out tiny, split-second pulses to keep the craft’s antenna pointed towards us, but they are getting old, and it’s taking a big effort to make Voyager 1 move. The solution was the (TCM), They haven’t been worn out by constant use over the last decades.
“The Voyager flight team dug up decades-old data and examined the software that was coded in an outdated assembler language, to make sure we could safely test the thrusters,” Chris Jones, chief engineer at NASA’s Jet Propulsion Lab, said in a statement.
