The star named Gliese581 has always interested astronomers and planet hunters
Around it goes the planet Gliese581 g. It sits right in the center of the Goldilocks zone, its roughly close to earth’s size which means it holds an atmosphere and it’s a rocky planet. The scientists have reasons to believe there is life there.
So why haven’t we fucking shot probes at this “planet of interest”!?

the speed of light is 299,792,458 meters per second which is about 371 million mph

Gliese581 g’s star is 20 light years away so if a probe were to travel at the speed of light it would take it 20 years to get there from earth.

light travels 3,249,960,000,000 miles per year
The fastest man made ship the Challenger was recorded as going about 18,000 mph. Which means it would travel 157,680,000 miles per year. That means for the challenger to travel one light year it would take 20,611 years for a man made machine to travel one light year.

20,611 times 20 = 412,22

It would take roughly 412,22 years to reach, forget Mars, lets fucking throw all we’ve got at this Gliese581 star filled with interesting planets.

500 years seems like alot but compared to the size of the universe... thats relatively close. Also our great great grand children will love us for doing this for them. Think of it like an a present in advance

>> No.1826195

First, any kind of useful means of propulsion is still under development (ion drive, solar sail, giving unidirectional fucks, ...). Second, we don't know the system well enough to get a probe in a stable orbit around the sun or one of the planets. The slightest deviations will be immensely magnified by the time required to reach the system. Third, it's 20 lightyears away. Communication has a 20 year lag. Even neglecting the amount of power needed to create a visible signal, and the difficulty in aiming at something so tiny at such a distance (the entire planets are barely visible), by the time you've got some preliminary data and sent some orbital corrections, chances are society will have already forgotten about the project, and it will all have been for nothing. Add to that that your probe needs to have power to do it's data gathering, and has to stay online long enough to send messages back and forth, this is simply impossible.

This is pretty exciting news but do we really need three threads?

>The scientists have reasons to believe there is life there.
Prior to mentioning this they flatly stated that talk of life or even water is wildly speculative at this point.

>So why haven’t we fucking shot probes at this “planet of interest”!?
Scientists just found it, chill out

20 light years is a long way to go with current technology. We have barely begun to seriously consider manned exploration of planets and planetoids. At this stage if we want more information about the cosmos we should build more advanced telescopes. In the future we may be better able to transverse inter-stellar distances but right now we get more bang for our buck out of better optics.

>we don't know the system well enough to get a probe in a stable orbit around the sun or one of the planets.

easy, you send 10 or more probes 1 year apart, the first probe gets there, shares the information with the other probes, if the first one crashes, the others won't risk the same mistake.

>Communication has a 20 year lag

they don't need to be controlled from earth, the robots can be autonomous and work together as a group.

It's hard but I think if we try hard enough and fund it more, we would be able to develop those kinds of robots

>> No.1826236

>>1826217

We're still a long way from creating reliable probes that can work autonomous like that. And it still doesn't solve the problem of getting a signal to Earth. Or the problem of a reliable power source that can keep the electronics from freezing during the trip.

nuclear power, solar power... etc etc..

>it still doesn't solve the problem of getting a signal to Earth

While the probes travel to get to Gliese581, they leave small crafts every ligh0t year, so that when they finally send back the information and photographs, it gets amplified so it doesn't dissipate. Also, it won't take too long for the signals to reach us as it would take for the probes to reach Gliese581

>also; stop being a pussy pessimist

>> No.1826257

1. Send probe to Gliese planet
2. Probe goes there, takes 5 shittons of pix
3. Probe returns to Sol
4. Probe continues to try to send data to Earth until someone listens
5. ???

It fucking sucks that we will never seriously explore space in my lifetime. But what about the following:

Say, 50 years from now, we have compiled a list of between tens of thousands and hundreds of thousands of "habitable zone" planets. Couldn't we then redirect SETI-like experiments to rigorously explore possible transmissions coming from these narrow points in the sky, rather than the current "we don't know where to look" approach that will most likely yield no results.

Just trying to pretend something interesting may happen in my lifetime, when in all likelihood it will simply be sad_frog.jpg

No, it doesn't mean that. A ship designed for interstellar travel would not be limited to a paltry 18,000 mph. A nuclear-propelled ship could (theoretically) reach speeds in the millions of miles per hour.
