More space news!

Recommended Posts

Opportunity may also have finally succumbed to the Martians after more than fourteen years; it has not yet responded after the winter.  More than thirteen years beyond its design life, "Trapped in a world he never made."

 

I'm going to contradict Old Man here.  Opportunity has not been metal.  It's been frickin' vibranium.

Like you said about Kepler, we are beyond mere legend here. We live in an age of myth and fable.

 

Though it's sometimes a sad myth, in that so many people don't realize they live surrounded by wonders. To paraphrase one of Clark Ashton Smith's epigrams, the veil of Isis floats before them, and they see only a petticoat.

They haven't completely given up hope since upcoming seasonal windstorms still have a marginal chance of clearing enough of the solar cells to get the thing operating again.

Not news, just some observations of how space battles would be like:

 

 

There is a game for this. "Children of a dead earth" claims to be "the most acurate space game." Indeed it goes as far as claiming to "be a simulation first, a game second":

He even has a blog with results from his own and palyer experiments:

Lasers: Get stopped by a whipple shield. And it is really hard to keep them on one point for long.

Nuclear weapons: Transmit a bit of heat, but are otherwise laughably weak compared to earth

One of the best weapons? A missiles with a nuclear warhead. The warhead explodes close to the enemy, forcing a solid penetrator out at high speed for maximum damage.

Humongo-ginormous lasers for zapping asteroids

 

A few vaguely interesting videos scattered around that linked page.

 

I found this via a bizarre Astrophysical Journal paper (certainly behind a paywall) about interstellar communications via not-yet-extant-but-not-too-fantastic-tech lasers with the quote

Quote

There is interest in building gargantuan lasers to accelerate small spacecraft at other stars. A 100 GW "DE-STAR 4" laser operating at a wavelength of 1064 nm, as proposed by {reference}, could be detectable at interstellar and even intergalactic distances by a civilization with our technology {another reference by the same author}. However, no continuous-wave laser has ever been built to that scale.

In case you missed this bit of weirdness, here's a new theory about Oumuamua

 

Where's that headdesk icon when you need it?

Hey, it's a hypothesis nearly as hypothetical as anything.

""It's certainly ingenious to show that an object the size of Oumuamua might be sent by aliens to another star system with nothing but a solar sail for power," Seth Shostak, a senior astronomer at the SETI Institute in Mountain View, California, said in an email. "But one should not blindly accept this clever hypothesis when there is also a mundane (and a priori more likely) explanation for Oumuamua — namely that it's a comet or asteroid from afar."

Coryn Bailer-Jones, an astronomer at the Max Planck Institute for Astronomy in Heidelberg, Germany, voiced similar objections. "In science," he said in an email, "we must ask ourselves, "Where is the evidence?, not "Where is the lack of evidence so that I can fit in any hypothesis that I like?"

"Why send a spacecraft which is doing this?" he said. "If it were a spacecraft, this tumbling would make it impossible to keep any instruments pointed at the Earth. Of course, one could now say it was an accident, or the aliens did this to deceive us. One can always come up with increasingly implausible suggestions that have no evidence in order to maintain an idea." "

This is actually a good example on how Conspiracy theories are halfway pointless. Or how a Conspiracy Theory and a Scientific one differ. I need to remember that one.

Reading this thread reinforces Creationism. And no  isn’t anti-science.  

How does reading this thread reinfoce Creationism?

 

All we talk about is space news, wich are usually science realted. Any creationism argument that might be cosntructed from this falls under: "The universe does not need to make sense."
