After falling continuously for an entire year, Scott Kelly is ready to hit the ground. With the goal of studying the long-term effects of microgravity on humans, his year is space has been something to keep an eye on. Always in good spirits, he is probably excited to come home, albeit apprehensive due to the dangers of returning to gravity after such a long time. Next Tuesday, March 1st, he will experience significant forces once again as he undocks from the ISS and is ferried home by the Soyuz capsule. Like wearing a weighted suit, coming home will be an...
In voodoo, new age, astrological, aura, garbage news, the Moon’s phase affects mental health and is a general consideration for werewolves. In real and useful science, the Moon is that occasional sight in the sky that gives us ocean tides and casually reminds us that the Earth actually has a big ball of rock falling around it. But in a strange twist, new data suggests that the Moon actually does affect one facet of human experience: Rainfall. A new paper from the university of Washington suggests that there is a slight dip in rainfall when the Moon is overhead or underfoot, due to the tidal force exerted by...
It always fascinates me to see videos and photographs from the International Space Station (ISS), how simple day to day activities are so altered because of the altered Physics of constant free fall in orbit around the Earth. Many of the videos are showing what people call the ‘effects of zero gravity.’ This is actually not the case. There is gravity in space. Let’s take a closer look at the situation of an ISS astronaut. If we do the math (I do realize the term ‘do the math’ turns away a lot of people, so I will keep it short),...
This past week, American astronaut Scott Kelly, currently on a one year stint aboard the International Space Station, broke the record of 363 days for most time logged in Space by an American. Kelly will continue to run up the tally, as he is just over halfway through his one year mission. His record comes from a total of four space missions, including two Shuttle missions and two ISS stays. While Kelly continues his mission to determine the long term effects of space flight on humans, his fellow ISS astronaut Andreas Mogensen has been testing a new skin suit developed...
Everything in the universe that has mass, has gravity. It’s easy to understand that the Earth, large as it is, has gravity, which pulls on us constantly, keeping us on terra firma. It’s just as easy to understand that other large objects have gravity, like the Moon, planets, and the Sun. However, it’s much harder to understand that every person on Earth has gravity. Strangely, you exert a force on the Earth, and on every other human. You also exert a force on every rock, tree, and creature that roams the Earth, and they all exert a force on you....
