In November 2026, a historic milestone awaits humanity's Voyager 1. The legendary probe will reach the "one light-day" mark, meaning it will be so distant that communication requires a 48-hour round trip!

Launched in 1977, Voyager 1 is now almost 16 billion miles away, traversing the silent interstellar void. At this range, radio signals moving at light speed take a full day to arrive. This two-day delay highlights the vast scale of our cosmos and the durability of 1970s tech.

As it drifts into the dark, the probe remains a testament to curiosity—reaching distances measured by time itself.

Voyager 1

No spacecraft has gone farther than NASA's Voyager 1. Launched in 1977 to fly by Jupiter and Saturn, Voyager 1 crossed into interstellar space in August 2012.

@mondinspace amazing, what You folks were capable to create, almost for eternity. 👍👍👍

@anorak_Al @mondinspace In high school, as part of physics class I wrote an extended essay about the proposed 'grand tour' mission to the outer planets, describing how it would work, what discoveries might be waiting, and such. That was in 1968. I aged with the Voyager probes and retired five years ago. I still have the notebook. Hand-written text, magazine clippings, dog ears...

@martinvermeer @mondinspace amazing. And it gives me the assurance, that there are normal, intelligent plp in US as well, not only braindead fascists like Trump, Vance and ICE killers, who dominate the news and totally destroy the reputation of the US as a sane country of the free and a valued partner, instead of "transatlantic relations - Terminators"!

@anorak_Al @mondinspace The American colleagues whom I had the honour to get to know in the geodesy and geophysics community were and are world class, and inevitably both space and Earth people. They're in a bad spot now 💔

@mondinspace

The saddest point is that I am almost sure that today technology is way less durable than the one of 50 years ago.

We fail ...

We did not make progress ...

For perspective, Earth's moon, which takes several days to reach at solar system space vehicle speed, is just over one light second away.

You would have to have left well over 50 years ago to reach the moon tomorrow if it were as far away as Voyager 1.
