>tfw these light sails could send us high definition pictures of exoplanets in 20 years

And yet nobody is funding this shit, why even live? Can Jeff Bezos take this over as his personal pet project right now?

Wasn’t the James Webb telescope supposed to get us some high-definition pictures of space? What happened to that thing, did it break already?

they are funding it
>The project was announced on 12 April 2016 in an event held in New York City by physicist and venture capitalist Yuri Milner, together with cosmologist Stephen Hawking, who was serving as board member of the initiatives. Other board members include Meta Platforms (then known as Facebook, Inc.) CEO Mark Zuckerberg. The project has an initial funding of US$100 million. Milner places the final mission cost at $5–10 billion, and estimates the first craft could launch by around 2036.

but do you mean why aren't more people doing this kind of thing, or funding it faster ? I don't know. Really i think the more funding put into creating space elevators would pay off a lot more later on. Right now it costs so much to put one thing into space, but if we could make it cheaper to get things into space then we could put a lot more shit in space, i guess that's obvious really but yeah a space elevator or some kind of hybrid elevator with an upper atmosphere launchpad or just anything to reduce the costs

Like the Cassini satellite and Huygens spacecraft that landed on Titan in 2005, it cost $3.26 billion, with the probe that landed on Titan costing over $300 million. That's insane. And the information we get from that is so low priority in the grand scheme of things that it's crazy to think these projects get funding over like the breakthrough starshot

I'd say the chances of it being blown up by a micrometeoroid travelling at that speed are 100%. To travel interstellar I think need either meters of pure tungsten as a shield (clearly impossible on such a spacecraft) some kind of magnetic shield or to clear the path with superstrong lasers

there's some people talking about that here. I'd assume the people working on the project would know the actual dangers though and the potential of the project to reach the destination

Rotating the sail into the direction of travel makes sense. Still I'd send a few of these rather than just one.

They will.
"The Starshot concept envisions launching a "mothership" carrying about a thousand tiny spacecraft (on the scale of centimeters) to a high-altitude Earth orbit for deployment. A phased array of ground-based lasers would then focus a light beam on the crafts' sails to accelerate them one by one to the target speed within 10 minutes, with an average acceleration on the order of 100 km/s2 (10,000 ɡ), and an illumination energy on the order of 1 TJ delivered to each sail. A preliminary sail model is suggested to have a surface area of 4 m × 4 m."- Wikipedia

100GW combined (non pulsed)
I wonder what they think regarding pulsed lasers... Probably the materials wouldn't withstand it, but that is a problem because most of our current laser tech is pulsed.
It would be interesting, could we just use that.
Let us estimate current laser capacity of pulsed lasers:
Example laser: Orion
Capacity: Petawatts
Pulse-time: 1ps
Let us assume it can do this pulse two times in the 10 minutes.
1PW*1ps=1000J (ok this is worse than I thought...)
2000J/10min=3.3W (Did I make a mistake somewhere or are we really building industrial facilities with continous power usages on the order of Watts?)

>in 20 years
Assuming they accelerate to like 20% lightspeed, don't miss their target, don't evaporate in the solar winds etc.
>>15389331
deploying the sail close enough to the sun could theoretically get you a good head start on that acceleration.

>>15392680
>only 10 minutes of acceleration each
you FUCKING WHAT
6 hours of acceleration could get them to 80% the speed of light, they could have their messages back in like 10 years instead of 24
and obviously that LaSeR aRrAy could very well be 10x the size to bring that 6 hours back down to 36 minutes

[Anonymous No.15392740]

Probably better to work on planet detection technology first, right?

The problem is the focus. It's too far away. I's crazy even so. I've done the maths:
a=dv/dt = 0.2c/600s = 100.000m/s^2
now s=at^2/2= 3e7m= 30,000km

We need to focus a laser on a 4*4m area that is 30,000km away...

Now if we want to reach 0.8c (neglect relativity for a sec)
dv=dt*a=0.8c => dt=2400s (40 minutes)
s=at^2/2=2.88e11m

This is 1.9 astronomical units away. You can't focus a laser on a 4*4m area that is 1.9au away.

Btw: Assuming the 100gw of power will be completely transferred into kinetic energy and they will reach 0.2c in 10 minutes you can calculate the maximum payload to be 32g, so they really need the focus.

I aren't think so mens. This is genuinely impossible. I thinks the idea is to aim at the general directions, and the laser disperses anywho over such distance

[Monadas No.15394369]

>>15393807
No it doesn't work. I thought so too, but again. Here are the calculations:
P=100GW
t=600s
v=0.2c

Now
[math]W=(\gamma-1)mc^2[/math]
where [math]\gamma=\frac{1}{\sqrt{1-0.2^2}}=1.0417[/math] as you want 20% of lightspeed.
then [math]m=/frac{W}{(\gamma-1)c^2}[/math]
given [math]W=P\cdot t = 100GW\cdot 600s=60TJ[/math]
we get [math]m=frac{60TJ}{0.0417\cdot (3\cdot 10^8m/s)^2= 0.045 kg[/math] (the extra 13g difference to my previous calculation are attributed to dark matter and rounding error and are thus negligible)
This assumes that all of your 100GW in the 10 minutes will hit the target.

As I said. It's pretty fucking crazy. The americans really think they can hit 4*4m in this distance (and this is not the only time they thought so, they want to build a gravitational wave experiment based on this as well, and power their air force with lasers (darpa project), and they already are running starlink with lasers (inter-satellite comms)).

They should send the probe to Epsilon Eridani instead. It's only 10 light years away and there's a much better chance of there being inhabitable planets.

if you were to send them continuously for 20 years and send data back along the chain you just might be able to pull it off, but it would be ridiculously expensive. Better hope data transfer is completely error free otherwise you're still getting mangled garbage on our end.
