NASA's Voyager probes continue to transmit data from interstellar space nearly 50 years after their original five-year mission parameters.
Quick answers
How long was the Voyager mission intended to last?
The probes were originally designed for a five-year mission following their 1977 launch.
What powers the Voyager probes?
The probes are powered by decaying plutonium.
How far away is Voyager 1?
Voyager 1 is more than 25 billion kilometres, or 15 billion miles, away from Earth.
The brief
Voyager 1 and 2 remain operational as the only human-made objects currently in interstellar space. Originally launched in 1977 with a projected five-year lifespan, the probes continue to function and transmit signals despite their extreme distance from Earth. Coverage from ScienceBlog.com, Make Tech Easier, 19FortyFive, it-online.co.za, and Space Daily highlights the mission's longevity and technical challenges.
Reports emphasize that Voyager 1 operates using less than 250 watts of power from decaying plutonium, with a signal strength comparable to a refrigerator lightbulb. Signal latency now exceeds 23 hours. Future developments include the ongoing trek of Voyager 1 as it approaches a distance of one light-day from Earth.
While engineers continue to manage the aging probes, coverage does not yet specify long-term projections beyond current operational milestones.
