Comment Disconnecting is the problem (Score 1) 202

The ISS doesn't need the Russian owned segments to carry on, but the Russian and non-Russian 'halves' have been so interconnected for so long the actual disconnecting may cause many failures. From hardware being naturally welded/fused together, to system information interchanges, to the flow of fluids, there could be many unexpected problems for a smooth disconnect. Should be fine after that.

Comment Re:test (Score 1) 155

It did not need the payload in place, and they used to do it without the payload on top.

With their experience built up and rocket design finally(?) standardized, they judged the risk to the payload was small enough to be worth saving an extra day or so of work to do the test without the payload. This is the first time a payload was or would have been harmed by a static fire on the pad.

Doing the test without the payload means after the test they have to lower the rocket, bring it back into the building to attach the payload, and then take it back out to the pad and run some more tests of the final integration.

Comment Re:ICBM Capability (Score 1) 74

A cryogenic fuel ICBM is terrible for quickly sending a bomb less than 500 km away. South Korea has no one to target beyond that, unlike North Korea who wishes to threaten the much further USA.

However, it is useful for upstaging North Korea who got to orbit first. Like USA using the Moon Landings to upstage the Sputnik and Gagarin achievements.

the company’s service agreements stipulate a minimum height of at least 50 miles, or 80 kilometers. Whitesides said that has been the case since Virgin Galactic first began selling rides on SpaceShipTwo about nine years ago.

Given their engine troubles, it is not known if it will reach 100km, and they are not required to.

Comment Re:Never seen so many allergies in people (Score 2) 134

Peanuts were found in the new world, and do not grow in Europe, so there would be no sickness from them until they were heavily imported after the Americas were discovered. After being introduced, many people may have died without it being diagnosed as "peanut allergy". Only recently have we gotten a lot better about keeping people alive who would have quickly died 1 or 2 hundred years ago.

Though I did read an article recently about babies not being exposed to enough 'things' was causing them to be more vulnerable to related things as they grew older, including peanut products.

Cherry-pick the best possible cases for the latter among the billions of local stars and one can be found. Huge difference between measuring the solid surface and subsurface composition of a very dimly lit object versus measuring how a very strong light changes when going through a gaseous atmosphere.
