MAN, it's fun being right
I posted about this in my giant space thread in the first few pages and you guys called me a crack pot! Well you can crack your own pot!
1.2 millinewtons per kilowatt in a vacuum

propellant-less space flight
that means mars in 70 days whenever we want + more

China has begrudgingly admitted that the country's first and only space station is most likely out of control -- and is expected to crash into the Earth's atmosphere next year.
The Tiangong-1 space station, launched in September 2011, means "heavenly palace" and was used to perform docking exercises in preparation for the country to build and launch a larger space complex by 2020.
In a press conference last week, Wu Ping, deputy director of the manned space engineering office, admitted that the station will likely come back to Earth in the second half of 2017, according to local media outlet Xinhua News.
"Based on our calculation and analysis, most parts of the space lab will burn up during falling," the official said, adding that the Tiangong-1 is currently intact and is orbiting at a height of approximately 370 kilometers.
It is hoped any debris will fall into the ocean -- otherwise, debris scattered over land masses could potentially cause some damage. If Chinese operators monitoring the station's orbit believe that collisions will occur, they will release a forecast internationally closer to the time.
Speaking to The Guardian, Harvard astrophysicist Jonathan McDowell said the station would re-enter the Earth's atmosphere "naturally," and so is not possible to predict where debris will fall.
"You really can't steer these things," McDowell told the publication. "Even a couple of days before it re-enters we probably won't know better than six or seven hours, plus or minus, when it's going to come down. Not knowing when it's going to come down translates as not knowing where it's going to come down."
China will launch the lab's replacement, the Tiangong-2, on Thursday.
Who knew you can get disposable space stations nowadays?

Once again, vindication for Goshin
I was right about the NASA Rocket, I was right about being cool, and I was right about the warp drive
you guys were all wrong!!!
The idea for an EmDrive was proposed in 2000 by a researcher named Roger Shawyer.
Since then four independent labs, including one at Nasa, have recreated the drive.
But the mysterious engine had baffled scientists because it appeared to violate the law of conservation of momentum, which states for every action there has to be an equal and opposite reaction.
This means the rocket can only accelerate forward if a force of equal magnitude is sent in the other direction - the rocket's exhaust.
Nasa's Eagleworks team is now ready to reveal its findings, it has been claimed - sending the physic world into a tizzy.
'It is my understanding that Eaglework's new paper has been today accepted for publication in a peer-review journal, where it will be published,' claims one user on the Nasa Spaceflight forum.
Earlier this year, an employee confirmed the team was working on the paper.
'The Eagleworks Lab is NOT dead and we continue down the path set by our NASA management.
'Past that I can't say more other than to listen to Dr Rodal on this topic, and please have patience about when our next EW paper is going to be published. Peer reviews are glacially slow,' Eagleworks engineer Paul March wrote on the same forum.
Earlier this year, a paper published in AIP Advances suggests the EmDrive produces an exhaust like every other rocket.

I'd post this in my space thread but I don't think anyone actually reads that thread anymore (regretfully)

A group at NASAs Johnson Space Center has successfully tested an electromagnetic (EM) propulsion drive in a vacuum a major breakthrough for a multi-year international effort comprising several competing research teams. Thrust measurements of the EM Drive defy classical physics expectations that such a closed (microwave) cavity should be unusable for space propulsion because of the law of conservation of momentum.
so here's a pretty decent nerd article about the shit going on at NASA
i'll start digging around some more and put more info up as I find it
the fact that it's got it's own article on this site is pretty significant though

in our galaxy, based on initial estimates from Kepler taking a survey of the sky for the last 4 years, there are 20 billion earths. The closet one is 12 light years away, much closer than the original thought of 40 light years.
Lets shoot radio signals at it
Sadly, Kepler died :(
Kepler has so far confirmed 135 planets beyond our Solar System.
But it still has more than 3,500 "candidates" in its database that have yet to be fully investigated, and the vast majority of these are expected to be confirmed as planets in due course.
Kepler completed its prime mission in November 2012, so it has already worked beyond its minimum requirements. But there is hope more science can be extracted from the spacecraft, with suggestions that it be turned over to look for asteroids, comets and exploding stars.
The US space agency, however, will have to decide whether a damaged Kepler merits further funding.
More planet-hunting missions are due to come online in the coming years.
The European Space Agency will launch its Gaia observatory before the end of 2013. Although its main goal is to map the positions of stars, it will do this so precisely that it should discover thousands of orbiting worlds in the process.

Apparently the Hubble telescope has captured pictures of two galaxies colliding. The Hubble site is calling this Galaxies Gone Wild! Though the lack of beer, guys with cameras and half naked drunk people makes me question the validity of that claim. Either way the pictures that Hubble snapped are very cool.

Austin computer gaming pioneer Richard Garriott said on Tuesday he intends to share his real-life spaceflight experiences with the Challenger Center for Space Science Education when he travels to the international space station this fall aboard a Russian spacecraft.

After expanding across Earth, the Internet is now set to spread into outer space to reach parts no network has gone before, one of its co-creators predicted Wednesday.
ICANN, which manages domain names and addresses, is preparing to launch a new format accommodating 340 trillion trillion trillion addresses.
