We're still getting data from both Voyager I and II, and each craft carries a message "... to instruct alien civilizations ... about humans and our lives on Earth."

It’s a cookbook.

Well, not exactly but what do you expect from Journalists?

Voyager is just a bit beyond the closest orbit of Sedna.

How far out is it, expressed in light hours? Go easy. I'm just a cook.

In what ways does what you posted contradict what’s in the article?

Because it's still inside the orbit of bodies orbiting Sol?

It's also not quite through the heliosphere shockwave, I understand. Facinating data coming in about that.

I don't know how far it is in light hours but for reference the new horizons space craft is about 3 hours and 17 light minutes from the sun.

In 200 years it will be on display at the Smithsonian

That's the order of magnitude I was looking for. Good enough for a cook, anyway. Space is vast, empty, and deep.

Sounds like a good place to set up a black-market business. ;)

I hope so. Our propulsion capabilities are getting better all the time.

At the current trajectory, more likely in Beijing.

According to JPL about 16 hours 53 minutes one way.

If only I had a dark flashlight and some dark energy batteries I could point it at the spacecraft and pull it back here before Monday.

True, but until we can find better brakes, that type of propulsion would only help in never-stop, one way trips.

So... you could go OUTRUN our space probe, but grabbing it and coming back.... ? Have you ever tried a hard left turn at light speed ?

Space is vast, empty, and deep.

Merely a matter of scale, and especially point of view. For instance, to those at the center of our galaxy, there is hardly any space at all.

This is true. The Project Deadelus proposals were all for flybys of Alpha Centauri or Barnard's star due to the speed which was expected to be around 12% the speed of light.

Something like 50 years getting there with a few months taking readings and launching probes as the main craft passed through.

Could a human survive aboard a spacecraft moving near light speed? Wouldn't the G-forces of acceleration be crushing?

It’s the acceleration that is the problem. If you accelerate gradually, no problem.

Think about traveling 60 mph in your car. Once you’re traveling at a constant speed of 60 mph, you don’t really feel anything. But if you go from a dead stop to 60 in a very short time, you feel the crushing sensation. If you accelerate slowly, you don’t feel it.

Same for an airplane - even higher speeds.

So theoretically, if you accelerate slowly, you could travel at near light speed with no crushing.

It isn't the speed that produces the G-forces, it is the acceleration. You can specify acceleration in G. For earth it is 32ft/sec/sec or about 9m/sec/sec.

You can approach C (lightspeed) in about 2 years at 1G with this reservation. Math heavy at link.

Good posts both, thanks!

From MH's link:

One major problem you would have to solve is the need for shielding. As you approach the speed of light you will be heading into an increasingly energetic and intense bombardment of cosmic rays and other particles. After only a few years of 1g acceleration even the cosmic background radiation is Doppler shifted into a lethal heat bath hot enough to melt all known materials.

Sounds like a rough trip! Guess we'll need to wait until the Star Trek deflector shields and warp drives are developed.

Not with Starfleet's finest inertial dampeners installed on your spacecraft!

The simple equation that relates force, mass and acce;eration is F = MA, and remembering that fact reminds me of a first-day physics question proposed to a classroom full of unicversity freshmen. The instructor pressed his hands hard against a wall and asked a question ...

"How much force am I exerting on this wall?"

The answer is simple ... Give it a try.

I think the best bet for extra solar system exploration could be called a “brute force probe”.

Basically an armored ball propelled by a nuclear ion drive, it gets to Jupiter via a conventional rocket booster, then uses Jupiter’s gravity to send it much faster, then finally the ion drive engages, getting it going at very high speed.

Only after it leaves the solar system, does its armor retract, allowing its instruments to work. Its nuclear power allows it to send a strong data signal to Earth.
