NASA has trialled an engine that would take us to Mars in 10 weeks
And may have inadvertently created a warp drive in the process.
By Fiona MacDonald

NASA scientists have reported that they’ve successfully tested an engine called the electromagnetic propulsion drive, or the EM Drive, in a vacuum that replicates space. The EM Drive experimental system could take humans to Mars in just 70 days without the need for rocket fuel, and it’s no exaggeration to say that this could change everything.

But before we get too excited (who are we kidding, we’re already freaking out), it’s important to note that these results haven’t been replicated or verified by peer review, so there’s a chance there’s been some kind of error. But so far, despite a thorough attempt to poke holes in the results, the engine seems to hold up.

On September 18th, 1980, Americans came very close to nuclear disaster. During maintenance on a Titan II missile in an Arkansas silo, an airman dropped a wrench, which plummeted 70 feet and punctured the missile, spraying rocket fuel everywhere. The incident was quickly covered up, but had the bomb exploded, millions would have been killed or irradiated. Source

humans getting a reputation amongst the galaxy for doing totally absurd and reckless things, like making absolutely ridiculous flight paths through asteroid belts, or hitting warp speed for a five mile trip, or devoting 90% of the power of a ship’s onboard computer to their personal laptop so they can torrent abba’s discography, or mixing rocket fuel with mentos to see what happens

and at first other species are like….. okay we’d better not have humans on the crew if they’re this dangerous….. but then when they notice the humans are actually getting a lot more done and advancing super fast because they take such absurd risks “just to see if it works” it becomes commonplace to have a group of at least four humans on every ship in the fleet

no other species previously had a word in their language that equated to “fuck it” but within a century “fuck it” is regarded as an immensely wise proverb

NASA is going green with eco friendly rocket fuel

Rocket launches are incredible to behold, but they come with some unwanted byproducts like soot and black carbon, which can absorb light, heat up the atmosphere and contribute to global warming. That’s why NASA is working on a new, more environmentally friendly type of rocket fuel.

Right now, most rocket fuel is hydrazine-based. NASA is developing a less toxic fuel called AF-M315E that uses hydroxyl ammonium nitrate. Its benefits extend beyond just being environmentally friendly.

ORAS may be trying to spread the lie that Maxie is intelligent but we all need to remember that in Emerald he tried to throw rocket fuel into a volcano and make it erupt. (pretty much everything he did was stupid)

IT's Official: NASA's Peer-Reviewed EM Drive Paper Has Finally Been Published
It works.
By Fiona MacDonald

After months of speculation and leaked documents, NASA’s long-awaited EM Drive paper has finally been peer-reviewed and published. And it shows that the ‘impossible’ propulsion system really does appear to work.

The NASA Eagleworks Laboratory team even put forward a hypothesis for how the EM Drive could produce thrust – something that seems impossible according to our current understanding of the laws of physics.

In case you’ve missed the hype, the EM Drive, or Electromagnetic Drive, is a propulsion system first proposed by British inventor Roger Shawyer back in 1999.

Instead of using heavy, inefficient rocket fuel, it bounces microwaves back and forth inside a cone-shaped metal cavity to generate thrust.

According to Shawyer’s calculations, the EM Drive could be so efficient that it could power us to Mars in just 70 days.

But, there’s a not-small problem with the system. It defies Newton’s third law, which states that everything must have an equal and opposite reaction.

According to the law, for a system to produce thrust, it has to push something out the other way. The EM Drive doesn’t do this.

Yet in test after test it continues to work. Last year, NASA’s Eagleworks Laboratory team got their hands on an EM Drive to try to figure out once and for all what was going on.

And now we finally have those results.

Meet The 'Rocket Girls,' The Women Who Charted The Course To Space
Before there were digital computers, there were "human computers," women who used pencils and paper to do the math that helped carry the U.S. into space. Nathalia Holt tells their story in a new book.

@npr (via this interview): 

”I was asked to graph the results coming back from the Explorer 1 satellite. And I worked most of the night, through the night, at JPL with my mechanical pencil and graph paper and light table that I was working on. And that was all the equipment that I had. …As I look back on so many things, I get more excited now than I did then. But it was exciting. I mean, it was great news that [Explorer I] was … in orbit around the Earth.”

The article talks about several of the women at NASA/JPL – meaning it might include two women previously featured here on RP:

Annie Jean Easley,  whose work contributed to the Centaur rockets….

…and Mary Sherman Morgan, whose work was instrumental in developing modern rocket fuel and propelling the US forward in the Space Race.

Human Waste Becomes Fuel For Spaceflight

by Txchnologist staff

When you’ve got to go, you’ve got to go. Now a research project conducted at the University of Florida has shown that when future astronauts need to take a bathroom break, they’ll be helping their rockets go, go, go.

Engineers have developed a two-stage digester process that turns human and organic waste into almost 77 gallons of methane per crewmember per day. The biogas, which also includes carbon dioxide, can be used to power rocket engines or other systems onboard spacecraft.

“We were trying to find out how much methane can be produced from uneaten food, food packaging and human waste,” said Pratap Pullammanappallil, an associate professor of agricultural and biological engineering. “The idea was to see whether we could make enough fuel to launch rockets and not carry all the fuel and its weight from Earth for the return journey.”

Rocket Candy: Sugar and KNO3 Rocket Fuel

Rocket Candy is a type of rocket propellant for model rockets made with sugar as a fuel, and containing an oxidizer. The propellant can be divided into three groups of components: the fuel, the oxidizer, and the additive(s). The fuel is a sugar; sucrose is the most commonly used. The most common oxidizer is potassium nitrate (KNO3). A traditional sugar propellant formulation is typically prepared in a 13:7 oxidizer to fuel ratio.

There are many different methods for preparation of a sugar-based rocket propellant. Dry compression does not require heating, only the grinding of the components and then packing into the motor. However, this method is not recommended for serious experimenting. Dry heating does not actually melt the KNO3, but it melts the sugar and then the KNO3 grains become suspended in the sugar. Dissolving and heating the propellant actually melts both of the components and combines them.

Open flame should never be used to melt the propellant, and the mix should always be heated in an oil bath, never over direct heat. Because rocket candy is extremely flammable, it should be prepared in small batches, out of doors or in an outbuilding, and using adequate personal protective equipment (eye protection at the very least). But Do Not Attempt This At Home.
