Apollo 11 and 50 years of research on Moon rocks

...solar wind composition experiment, a passive seismic experiment to detect lunar ‘moonquakes’, and a laser ranging retroreflector to very precisely measure the distance between the Earth and Moon. But perhaps their most important task was to collect samples of the lunar surface. Apollo 11 returned 22kg of lunar samples to Earth. The Apollo 11 landing was the first of...

Golden Globe Ocean Race: Monsoon and its role on regulating global climate in the past

...solar insolation than the southern hemisphere. As a result the northern hemisphere landmass heats up and the warm air rises creating a low pressure. In contrast, the ocean waters are slow to warm and thereby air above the ocean is cooler, moist and dense creating a high pressure. [The specific heat of water is greater than dry land, therefore water absorbs and emits heat...
