EmDrive, a Supposed Fuel-less Engine, Is Knocked Down Again, Gizmodo

"Five years ago, NASA researchers experimented with an object called the EmDrive (or electromagnetic drive), a Y-shaped metal chamber in which, they reported, thrust could be produced without propellant. Such a contraption would refute core principles of physics as we know them and eliminate a huge barrier to deep space travel by nullifying the need to carry fuel. ... If that sounds too good to be true, well, other scientists had the same thought. Since that paper, published in the Journal of Propulsion and Power, plenty of research has come along explaining where EmDrive's original math went wrong."

Keith's note: This is what happens when a NASA field center (JSC) has a center director who funds a pet project that has not undergone adequate review - especially when the proposed work violates the laws of physics. You end up with quack science - just like the NASA Langley and NASA Glenn folks encountered with their equally bogus cold fusion research pet project (see "Quack Science: Why Are NASA Glenn and Langley Funding Cold Fusion Research?"). Don't get me wrong, NASA should be pushing the boundaries of the possible. But if you look at these warp drive and cold fusion things, NASA did not do due diligence in funding them. they were less than responsive when asked about them, and if you submit a media inquiry now they act as if they never heard of the projects that used scarce tax dollars.

NASAWatch Is 25

How It Started | How It's Going

Keith's note: NASAWatch turns 25 on 1 Apr 2021. It started as "NASA RIFWatch" on 1 Apr 1996 with this post "RIF at NASA In Summer 1997?". The website was first hosted on a Mac Classic II on a 128 kbps ISDN line in my old little condo in Reston, Virginia (see 20 Years Ago Today: The Seeds of NASAWatch). Here are a few things from those early days that are still online:

- Rogue Webmasters, Government Executive, 1 Oct 1996
- NASA's Most Important Asset, Gerry Griffin, 31 December 1996
- Dan Goldin Comments to the Space Science Advisory Committee (SSAC) Meeting, 6/17/96
- Changes in Thinking At NASA November 29, 1996, PBS News Hour
