The Voyager probes were the first spacecraft to cross into interstellar space.

Each year , the aging spacecraft lose about 4 watts of power.

The Voyagers are powered by heat from decaying plutonium, which is converted into electricity.

Linda Spilker , the Voyager mission’s project scientist, spoke to Gizmodo .

Spilker:Â The spacecraft was built in the 1970s , and so that’s the technology that we had in those days .

The challenge with these aging components is, how long until a key piece fails? We’re well past the warranty of four years . We also have less power every year , about 4 watts less power.

Spilker: Most of the people working on the Voyager mission are new.

Some of the engineers had a big diagram up on the wall of what the computer looked like and all the paths that it had to go through to figure it all out.

Some people who retired, who were there in that time frame, have come back and now work part time.
