That would be pretty hilarious, although I would hope to have some compact fission/fusion reactor with about twice the expected life of the trip as a primary power source...

Things do go wrong... I remember an old Heinlein story where Cu (I think) was used to power their star-drive and somebody sent him and another astronaut on a 'one way trip to oblivion'.

They managed to react enough copper out of her wedding band to effect an escape, since Heinlein only killed a few of his protagonists

You can look up the products and see which ones have US-sided tariffs that are being eliminated

For example, non-volatile memory

Switches and routers ...have no existing US tariffs, and we would benefit from other countries dropping their barriers to trade

However, stereoscopic microscopes enjoy a 5-7% US tariff, and will see competition

It will take a while to sort out, but this may work in our advantage

In the summary they mention that they had retired Foreign Personnel reviewing information to determine if it was classified or not.

So, apparently there was an attempt to identify classified information, and a dispute of what should have been deemed classified.

It would seem that is where the quibbling is, unless they intentionally ignored the advice of these reviewers

Submission + - Elon Musk offers explanation for loss of Falcon 9 mission

garyisabusyguy writes: This Forbes article provides the best analysis of the loss of the last Falcon 9 mission based on information released by Elon Musk.
1. Sound triangulation led them to identify a strut holding helium tank as root cause where the falling helium tank pinched a line causing overpressure in the LOX tank.
2. The failure occurred at 2,000 pounds of force, and the struts were rated at 10,000 pounds of force. They initially dismissed this as a cause until sounds triangulation pointed back to the strut
3. Further testing of struts in stock found one that failed at 2,000 pounds of force, with further analysis identifying poor grain structure in the metal, which caused weakness
4. It will be months before the next launch while SpaceX goes over procurement and QA processes all struts and bolts, and re-assesses any "near misses" with Air Force and NASA
5. Next launch will include failure mode software, which will allow recovery of the Dragon module during loss of the launch vehicle since they determined that it could have saved the Dragon module in this lost mission

I'm still waiting for them to stick the landing,which could be a way in the future

In this case the 'receiving antenna' is the belly of the spacecraft, which is covered in ceramic tiles designed to covert the energy into heat and act as a heat exchanger. This introduces interesting problems with targeting since the large ground array all needs to hit the same few hundred square feet of target

There is a whitepaper linked from the company website:

The short story

Microwave provides source of energy by targeting heat-absorbing material
Heat exchanger is used to heat and compress Hydrogen to 150 atmospheres
Hydrogen is fed to aerospike nozzle, which provide impulse thrust gt 750 seconds
Claims launcher will be able to provide 8% to 12% of total weight as cargo

Right now most of the website is pretty pictures and videos, time will tell

Great find, it is important to remember our history in order to avoid repeating it

The lies that the neo-cons would eventually use to justify war on Iraq are clearly laid out on the front page:
" Our ability to ensure that Saddam Hussein is not producing weapons of mass destruction, therefore, has substantially diminished. Even if full inspections were eventually to resume, which now seems highly unlikely, experience has shown that it is difficult if not impossible to monitor Iraq’s chemical and biological weapons production. The lengthy period during which the inspectors will have been unable to enter many Iraqi facilities has made it even less likely that they will be able to uncover all of Saddam’s secrets"

What we found out after destroying the country and destabilizing the region was that the inspectors had been COMPLETELY effective in wiping out Saddam's weapons programs and that they only evidence that they were ever able to find came fro munitions created with Western aid in the 80's when Iraq was at war with Iran.

Even more important, it contains the list of 'signatories' to the lies. We should never forget who these people are and NEVER let them gain control of our government again:
Elliott Abrams - Richard L. Armitage - William J. Bennett - Jeffrey Bergner - John Bolton - Paula Dobriansky - Francis Fukuyama - Robert Kagan - Zalmay Khalilzad - William Kristol - Richard Perle - Peter W. Rodman - Donald Rumsfeld - William Schneider, Jr. - Vin Weber - Paul Wolfowitz - R. James Woolsey - Robert B. Zoellick
