Used anexplosively formed projectileto annihilate newer material and get closer to the asteroid's core. Super cool expedition.

Having an old style tag like 'VK3DRB' he is obviously an 'older' radioguy over here, and probably older than you. Your Culture is supposed to respect your elders, and 'SON' doesn't cut it mate.Surely China can understand that the Western World in general, but at least pertaining at present to Australia, that theirpresent & continuing pressures (abuse!) towards Australian Exports is GOING to awaken proverbial 'Sleeping Dogs'.The Chinese, although 'trading' with us mere scum bags in the West, have always been bullies in this World of ours.We can 'sort' of understand it, as that is how they have 'ruled' their own provinces for a LONG time. They 'almost' got itright in temporarily accepting Hong-Kong, but we (the World!) has witnessed that friendly alliance blown out the waterrecently, when they thought they were loosing control. (Heaven forbid!).By their very nature, having been in 'control' for so long, they literally can notunderstandorstandthat some other Countryof equivalent infidels DARE to question them!? And why??? because Australia DARED to initially question the knowledge ofthis recent fucking virus?? (Trump calls it the 'China-Virus' being a smart arse, but no restrictions on the U.S.!).You see, Australia has not, and will not, respond to or bow down toBULLIES!!So now Australia has DARED to open upcountless new trade agreements with greatly reduced tariff agreements with NUMEROUS other countries now!!...How dare we!! If one doesn't know what 'FU' means, then look it up...

Earlier this year, I stuck out my neck for you because I valued your opinion, as much as everyone else's, and asked the forum management to examine the stance on certain tenacious topics.Whilst my grumble caused a raucous, I was spared the axe-swing to the neck and was tactfully responded to with a rational explanation of the alternative standpoint at the same time appreciating my position. It's water under the bridge.It's part of western culture to criticize the establishment. Western culture is also the reason why I'm not offended if you prefer to favor national pride by default instead of a rational discourse.What does 'GLGGHF' mean?

content: Quote from: BravoV on December 17, 2020, 02:35:31 pmNational gifts? The article is from the South China Morning Post (headquartered in Hong Kong, which is now under the Chinese Communist Party control). "Relevant countries" of course excludes Australia without a doubt unless we yield to the Chinese side and allow their government controlled companies to infiltrate Australia. The USA is also excluded in the research unless they also yield to the demands of the CCP.Compare with Japan's Hayabusa2 asteroid-sampling mission. A great example of international cooperation between genuinely friendly countries. A mission so fantastic, it sounded like science fiction. It will be interesting to find out what knowledge collected from the pebble/soil samples will yield for the benefit of man's understanding of the universe. This project is model of honesty, integrity, cooperation and incredible engineering skill. I recall the friendly, cooperative, and strong technical relationship between USA and Australia which resulted in mankind transmitting the live video of Neil Armstrong first stepping on the moon. No strings attached.

There's new science to be done. Also new is to achieve this with a much smaller investment in regards to money and human risk. It's definitely an advancement to be celebrated and congratulated.

The method of its extraction and delivery is much more interesting.You know what i mean? It is impossible to say anything about the Earth if you dig a little soil near your house or near my house. We will not find there, most likely, anything of value: no gold, no oil, no artifacts of ancient civilizations.

content: Quote from: S. Petrukhin on December 20, 2020, 06:07:12 pmYou consistently oversimplify things to the point of removing all detail, to then claim there's nothing new or interesting to it. That's like claiming Columbus' trip to the US was nothing special because we've discovered lands before and we have continents at home. We don't need new scientific discoveries because we've had many in the past. We don't need new music because we've had music in the past. It's selecting the arguments to fit a foregone conclusion.The samples brought back new soil from the Moon, which will yield new data about how the Moon developed and by extension Earth's history. Contrary to Earth the Moon isn't continually resurfaced so there are many clues about the history of our solar system to be found on the surface. Both similar and very different samples provide data which strengthen or upend existing views. The newly developed technology is likely facilitate further exploration and science. There's a lot we learned and to be learned. To be human is to push boundaries, although some prefer to cling to what they know and stay put.

The story was passed down in the Norse sagas.As far as De Soto there is a book that was recently translated into English called "The Florida of the Inca" (Garcilaso de la Vega) which is pretty interesting, even if one is not so into history.
