The brief
Voyager 1 and 2 are currently the only human-made objects in interstellar space. Despite being designed for a five-year lifespan, both probes remain operational and continue to transmit data back to Earth.
Coverage from Space Daily, Make Tech Easier, and 19FortyFive emphasizes the technical constraints of Voyager 1, which is transmitting from over 25 billion kilometers (15 billion miles) away. The signal is powered by less than 250 watts of decaying plutonium and a radio transmitter described as weaker than a refrigerator lightbulb.
According to it-online.co.za, Voyager 1 is on track to reach a distance of one light-day from Earth. ScienceBlog.com highlights the legacy of the engineers who built the probes knowing they likely would not see the mission reach interstellar space.
