Voyager 1 becomes the first man-made object to leave our solar system.

And it’s exploring the galaxy with only 68 KB of memory.

At the edge of the heliosphere, you wouldn’t know by looking whether you left the cradle of humanity behind and floated out into interstellar space. You would just see unfathomably empty space, no matter which side of the invisible line you were on.

But scientists now have strong evidence that NASA’s Voyager 1 probe has crossed this important border, making history as the first human-made object to leave the heliosphere, the magnetic boundary separating the solar system’s sun, planets and solar wind from the rest of the galaxy.

“In leaving the heliosphere and setting sail on the cosmic seas between the stars, Voyager has joined other historic journeys of exploration: The first circumnavigation of the Earth, the first steps on the Moon,” said Ed Stone, chief scientist on the Voyager mission. “That’s the kind of event this is, as we leave behind our solar bubble.”

Voyager 1 has only 68 KB of memory on board — far less than a smartphone, said Suzanne Dodd, Voyager project manager. Scientists communicate with the spacecraft every day.

“It’s the little spacecraft that could,” she said in a NASA press conference.

The probe now has a totally new mission, Stone said.

“We’re now on the first mission to explore interstellar space,” he said. “We will now look and learn in detail how the wind which is outside, that came from these other stars, is deflected around the heliosphere.”
