Solar mission about to leave — NASA is scheduled to send human technology closer to a star than ever before from August 11th. What they learn could change our understanding of, well, the whole galaxy.
The Parker Solar Probe is a mission set to orbit the Sun at just 6.1 million kms. Earth’s average distance is 149.6 million kms; Mercury’s average distance is 57.9 million kms. The spacecraft will need to shield itself from temperatures as high as 1377C in order to find answers to the many questions scientists still have about our Sun and stars in general.
~ I guess it will have to leave during the day, or it won’t be able to find it … [lol]
Commercial space crew announced — NASA has announced the first astronauts who will head to the International Space Station on a commercially built spacecraft. These US astronauts previously flew aboard Russian spacecraft to get to the ISS. The coming launches will be the first from American soil since the Space Shuttle’s 2011 retirement, according to a NASA news release. The astronauts will travel in the new Boeing CST-100 Starliner and SpaceX Crew Dragon. The team consists of 9 men and women from across the US.
~ Commercial, hey? So it should be called the Starship Enterprise.
Future faming — How do you feed an increasing number of people without harming the environment? As it turns out, growing as much food as possible in a small area may be our best bet for sustainably feeding the world’s population, according to new research. It all comes down to how we manage greenhouse gases and climate change …
~ Didn’t see that coming. Well, OK, but didn’t we all?
Mayan drought may have ended them — The ancient Maya were an innovative people who constructed intricate cities throughout the tropical lowlands of the Yucatán Peninsula, communicated using one of the world’s first written languages, and created two calendar systems by studying the stars. But despite their achievements, the thriving Mayan civilisation mysteriously collapsed sometime between the eighth and ninth centuries. We still don’t know exactly why.
The general consensus is that the Mayan collapse was caused by a number of things, including disease, war, and other sociopolitical conflicts. One natural factor may have contributed to all of these issues: drought. A particularly bad drought would have made it difficult for the Maya to collect enough drinking water and to irrigate their crops. It also could have encouraged the spread of disease and increased the strain between Mayan leaders and their people.
~ And I reckon the Russians were involved.
Rare blue diamonds deep in the Earth — Just 1 out of 200,000 diamonds are blue, and eventually reach the surface through volcanic eruptions. Like all diamonds, they are made when carbon comes under intense pressure and extreme heat deep inside the Earth. As they form, they can trap tiny bits of rock inside – like fossils in amber. Steven Shirey, a geochemist at the Carnegie Institution for Science in Washington, and his colleagues used lasers to examine the diamonds’ imperfections – slivers of embedded rock – at the Gemological Institute of America. The researchers suggest that boron in the ocean floor was pushed down when plates that make up the Earth’s crust collided. The element allows the stone to absorb some red light, so the diamond looks blue.
~ So, once they can dig deep enough, they won’t be rare any more.
