“And so the concept of warp drive is to say, all right, let’s take our ship, let’s build a bubble of space-time around it, and then we’ll have that propel us faster than the speed of light,” she says. “What warp drive is doing is basically saying that there is no law of physics that says space-time itself can’t go faster than the speed of light,” says Dr Erin Macdonald, astrophysicist and science consultant for Star Trek. The key that makes it possible is that, technically, the ship itself doesn’t travel faster than light. The first scientific theory of warp drive came about in 1994, when theoretical physicist Miguel Alcubierre used Einstein’s theory of General Relativity to develop a framework that would allow faster-than-light travel within the confines of the laws of physics.

Unless the Voyager probes collide with something or are picked up by alien space explorers, they will, in theory, keep flying until the end of the universe. Then the two spacecraft will fly forever outward, each bearing a gold audio-visual disk containing greetings from the people of Earth. Scientists estimate, though, that within about five years, Voyager 1 and Voyager 2 will run out of the decaying plutonium that fuels their RTG power generators. That the Voyager spacecraft are still returning good science from billions of miles away is a testament to the state of the art of space technology in the late 1970s.

Voyager 1 flew past Jupiter and Saturn before heading to the outer boundaries of the solar system. Voyagers 1 and 2 launched in 1977 within 16 days of one another on a mission to explore the outer planets. The information from the boundary between the solar wind and interstellar space is just the latest that the two Voyager spacecraft have imparted. It's also similar to the plasma density jump experienced by Voyager 1 when it crossed into interstellar space.” The data being returned by both spacecraft – having passed beyond the heliosphere, past where solar winds still blow plasma outward from the sun – have scientists excited.Īs soon as Voyager 2 left the farthest reaches of the solar wind, the density of plasma actually jumped, according to . “The marked increase in plasma density is evidence of Voyager 2 journeying from the hot, lower-density plasma characteristic of the solar wind to the cool, higher-density plasma of interstellar space. Her companion spacecraft, Voyager 1, accomplished the feat in 2013.
Voyager 2, first launched in 1977, is the second human-made machine to have officially entered interstellar space.
