Australian College Student’s ION drive surpasses NASA

November 1, 2015

An Australian university student has reportedly developed a new kind of ion space drive that absolutely obliterates NASA’s current fuel efficiency record.

Ion drives are propulsion systems that basically work by throwing particles backwards really, really fast in order to propel a spacecraft forward. NASA’s current record holder for fuel efficiency is its High Power Electric Propulsion, or HiPEP, system, which allows 9,600 (+/- 200) seconds of specific impulse, which is pretty impressive. But the new drive developed by University of Sydney PhD student Paddy Neumann has achieved up to 14,690 (+/- 2,000), according to student newspaper Honi Soit.

The is an incredibly exciting claim, but we need to be clear that the results have yet to be published in a peer-reviewed journal, so we need to take them with a proverbial grain of salt. Neumann has, however, applied for a patent and will be presenting his results on 30 September at the 15th Australian Space Research Conference, where we’ll hopefully be presented with some more concrete evidence.

What’s so innovative about the new drive is that it uses a whole new type of fuel. NASA’s HiPEP system runs on xenon gas, but Neumann’s ion drive can instead run on a range of metals, with the best results currently achieved using magnesium.

These types of metals are readily available in space junk, which means that the system could be a whole lot cheaper, and could one day be fuelled using material harvested from old satellites. If we could work out how to do that, it would make things even more affordable, as it would save on the exorbitant cost of carting fuel into space.

The Neumann ion drive works by hitting the fuel source – in this case solid magnesium – with electric arcs, which causes ions to spray off. These ions are then channelled through a thrust-producing magnetic nozzle, resulting in forward propulsion, just like you’d get if you were floating in a pool on a lilo and threw beer cans behind you (because who hasn’t done that?)

“Unlike current industry standard chemical propulsion devices, which operate through short, high-powered bursts of thrust and then coasting, Neumann’s drive runs on a continuous rhythm of short and light bursts, preserving the fuel source but requiring long-term missions,” write Joanna Connolly and Peter Walsh from Honi Soit.

But while the Neumann Drive outperforms NASA’s HiPEP system when it comes to fuel efficiency, it falls short when it comes to acceleration, which means it probably wouldn’t be ideal to power a spacecraft off a planet. But it could easily be paired with other propulsion systems to transport cargo and passengers over long distances without having to stop and refuel.

Neumann told Honi Soit that with some tweaking the system could potentially power a spacecraft to “Mars and back on one tank of fuel”.

For some reason, the University of Sydney’s commercial arm decided not to commercialise the invention, and so the intellectual property has passed back to Neumann two other researchers that were involved in the project. They’ve now applied for a patent under the company name Neumann Space, and are looking to secure funding to further develop the propulsion system. If the claims hold up to further testing, we’re pretty sure that SpaceX, Virgin Galactic, or NASA would be interested.

In a week where we’ve seen a 14-year-old boy persecuted for experimenting with engineering, it’s pretty awesome to hear about a student’s ingenuity leading to the creation of a device that could one day help to transport humanity further through space. We’re looking forward to hearing more about Neumann’s ion drive at the end of the month.

SpaceX Reusable F9R Test 4 times higher

May 4, 2014

In my opinion, this should be front page news, since SpaceX can eventually reduce the cost of using rockets by a factor of 100….

If you’re like me and want disclosure and contact with E.T.’s, then we should support SpaceX, because the faster, cheaper, safer, and more often we get to space, the sooner we will bump into our E.T. friends and neighbors.   The faster we get privately funded missions to the moon and Mars, the sooner the real evidence of E.T. structures will be exposed in a way that our governments cannot deny.

SpaceX Grasshopper rocket makes a half-mile hop

October 13, 2013

 

SpaceX’s Grasshopper rocket prototype made another record-setting vertical takeoff and landing this week from the California-based company’s test pad near McGregor, Texas. But what’s really cool about Oct. 7’s half-mile (744-meter) ascent and controlled descent is the amazing view from a remote-controlled hexacopter that captured the video clip.

This is what a rocket launch and landing is supposed to look like.

The 10-story craft is testing the technologies that would be required to have the first stage of a rocket fly itself back to base after launch. The Grasshopper consists of a Falcon 9 first-stage tank, Merlin 1D rocket engine, landing legs and a steel support structure.

Last month’s launch of a Falcon 9 v1.1 rocket provided a real-world test of rocket reusability, and although the test wasn’t completely successful, it’s only a matter of time before SpaceX gets it right. Then everything changes.
