NASA May Have Accidentally Created a Warp Field

Interesting, if true: NASA May Have Accidentally Created a Warp Field:

Which brings us to today’s warp field buzz. Posts on NASASpaceFlight.com, a website devoted to the engineering side of space news, say that NASA has a tool to measure variances in the path-time of light. When lasers were fired through the EmDrive’s resonance chamber, […]

Inflatables Moving Closer to Use

Bigelow’s already demonstrated that inflatables can be deployed and operated in space. Now they’re moving closer to demonstrating an inflatable habitat with actual people in it: On the BEAM: Headed for the Space Station.

In its packed configuration tucked aboard SpaceX’s Dragon resupply spacecraft, BEAM will measure approximately 8 feet in diameter.

Once BEAM is […]

How Far We’ve Come

Since just 1996: Infrared Camera:

The camera weighs only 9.9 pounds and measures 4.4 inches wide, 10.3 inches deep and 7.2 inches long. The prototype plugs into a wall socket for power but the camera can readily be converted to battery power for portability.

That eyeball ain’t gonna fit on a cubesat.

‘Digital nose’

‘Digital nose’ on a chip can sniff out diseases

Heh. I suggested that application for a sensor technology LM owned, three years ago, on the same inspiration (dogs being trained to sniff out cancer).

Test Stand to Nowhere

NASA’s $349 million monument to its drift

Ugh.

And naturally, because the article mentioned the Tea Party, it’s somehow the Tea Party’s fault. Sure, Republican officials appear to hold much of the blame in this, but WaPo appears to have guessed correctly that its loyal readership/cult would snap up the bait and blame it all […]

The Space Applications are Obvious

New Nanomaterial Takes the Stink Out of Submarine Air

Unlike amine, which is a liquid, the new material looks like sand. In fact, it is sand, except it is covered with tiny pores, each filled with molecules that selectively pull CO2 out of the airstream. Together, sand grain and molecule are called Self Assembled Monolayers […]

Razr Burn

Having tried to resurrect mine last fall in hopes of unlocking it and using it Europe (and having just switched from Blackberry to a Galaxy S5 last week), this caught my attention: Razr Burn: My Month With 2004’s Most Exciting Phone.

Her cellphone experience is significantly different from mine.

Maps: I gave up using anything […]

Supersonic Decelerator Test

NASA Is About to Test a Mega-Parachute at the Edge of Space

The system in question is a combination of a large parachute (Supersonic Disk Sail Parachute) and the smaller of two inflatable decelerator designs (the 6m Supersonic Inflatable Aerodynamic Decelerator for robotic missions, or SIAD-R). (More here [pdf])

I’ve seen images of the larger […]

3D Printing and Laser Machining…At the Same Time

Very cool: Hybrid Machine Combines Milling and Additive Manufacturing

By using laser deposition to build up the part, while employing milling throughout the process to machine critical features as the part is taking shape, the machine can produce a component through additive manufacturing while also producing it to its completed tolerances within the same cycle.

[…]

Meshnet Instead of Internet?

Meshnet activists rebuilding the internet from scratch

This sounds to me like a next-generation version of UUCP (I think it was called) from back in the day. I wondered when the PRISM, etc. scandals broke if something like that would make a comeback.

What’s needed for this to take off (apart from Americans taking enough […]
