How can we make interstellar travel?

How can we make interstellar travel?

To make interstellar spaceflight more reasonable, a probe has to go really fast. On the order of at least one-tenth the speed of light. At that speed, spacecraft could reach Proxima Centauri in a handful of decades, and send back pictures a few years later, well within a human lifetime.

Which of the suggested methods for interstellar travel do you find most plausible?

When it comes to interstellar travel, the best approach may be a laser-pushed light sail. First proposed by Robert Forward in a 1984 paper, this is just like a solar sail that is pushed along by light – but it is driven along by an intense laser. Beam-powered propulsion poses several key challenges.

What is the best way to travel in space?

While the only way up to space is via a rocket, there are two ways to come back down: via a winged vehicle, like the space shuttle or Virgin Galactic’s SpaceShipTwo, or via a capsule, like Apollo, Soyuz, and Blue Origin’s New Shepard.

What are the main challenges of interstellar travel?

Each design has its own way to overcome the main challenge of interstellar travel: the distance to the stars. At 4 light-years away, Proxima Centauri is the closest star to the Earth (other than our own Sun, of course).

Will we ever be able to go to interstellar space?

There’s no law of physics that outright forbids it. But that doesn’t necessarily make it easy, and it certainly doesn’t mean we’ll achieve it in our lifetimes, let alone this century. Interstellar space travel is a real pain in the neck. If you’re sufficiently patient, then we’ve already achieved interstellar exploration status.

How fast do interstellar space probes travel?

So, great; we have interstellar space probes currently in operation. Except the problem is that they’re going nowhere really fast. Each one of these intrepid interstellar explorers is traveling at tens of thousands of miles per hour, which sounds pretty fast.

How long would it take to travel to the stars?

Each design has its own way to overcome the main challenge of interstellar travel: the distance to the stars. At 4 light-years away, Proxima Centauri is the closest star to the Earth (other than our own Sun, of course). With conventional rocketry, it would take around 137,000 years to get there.
