onism – n. the frustration of being stuck in just one body, that inhabits only one place at a time, which is like standing in front of the departures screen at an airport, flickering over with strange place names like other people’s passwords, each representing one more thing you’ll never get to see before you die-and all because, as the arrow on the map helpfully points out, you are here.
Ironically due to our connected world we’re all the more aware of the blank spots in our maps.
The numbers are scary. Sitting really seems to be bad if the observational studies and meta analysis studies are to be believed. Sitting for lengthy periods of time contributes to all sorts of nasty diseases like cancers and heart disease. It’s a wonder I’ve reached this age at all!
It doesn’t matter how much you exercise, it has no effect on how bad sitting is for you. You’re better off getting up and walking around for 2 minutes every half hour or hour than doing that intensive hour of walking in the morning. (damn)
And the findings were sobering: Every single hour of television watched after the age of 25 reduces the viewer’s life expectancy by 21.8 minutes.
By comparison, smoking a single cigarette reduces life expectancy by about 11 minutes, the authors said.
Looking more broadly, they concluded that an adult who spends an average of six hours a day watching TV over the course of a lifetime can expect to live 4.8 years fewer than a person who does not watch TV.
The last week has been quite an amazing one in human history. We have photographed up close all the planets (and ex-planets) of our solar system. What our ancestors saw as mere points of light in the sky are now full colour images that anyone can see. It’s really amazing.
Still, there were surprises in the form of a death star. George Lucas must have been there already!
Clyde Tombaugh was the man who discovered Pluto in 1930. He died in 1997 before this mission launched and a portion of his ashes were carried by the New Horizons craft. His are the first ashes to be carried to Pluto, and the first to eventually leave the solar system as New Horizons is on an escape trajectory!
In typical Scott Manley style, he has produced a video using Kerbal Space Program explaining how New Horizons was launched by NASA. He has lots of background information on the rockets used and he’s as interesting as always.
Here’s another, more cinematic, depiction of the launch by Youtube user “winged”. This one is shorter and visually more interesting but lacks the narration of Scott’s video so you should definitely watch both!
There’s two cameras that more or less operate in visible light: a color camera which is a medium resolution camera (Ralph), and then there’s a grayscale or black and white telephoto camera (Long Range Reconnaissance Imager, or LORRI).
Our long range pictures of things that are going to give us our highest resolution images will be taken LORRI. And the color pictures will be taken with Ralph. We can actually combine the colors from Ralph to colorize LORRI’s pictures.
And then there is an imaging infrared spectrometer that will also makes pictures of a sort. But they’re mostly compositional information, like what Pluto and its moons are made out of.
Another constraint on the mission was that Ralph had to take photos using only the sun’s dim light that reaches Pluto. During its flyby, New Horizons will photograph the side of Pluto that’s turned away from the sun. This side is lit solely by the sun’s light reflecting off Charon. This is like taking a photo using just the light from a “quarter moon” on Earth, a lead optical engineer for the mission told me in an email.
So Hardaway and her team designed Ralph for the exact light conditions that New Horizons would have to operate in. “This camera isn’t adjustable. It’s designed very specifically for conditions at Pluto,” she says.
The craft has successfully passed through the Pluto system according to signals received earlier today. It’s going to take months for all the scientific data collected to be transmitted back to Earth but hopefully we’ll see more detailed photos of Pluto and it’s moons over the next week. I’ll update this post with more when I get it!
Finally for now, New Horizons took many photos on it’s way to Pluto including this stunning montage of Jupiter and one of it’s moons, Io. Check out the mission homepage for more!
Update at 2015-07-15 21:00 UTC+1: NASA have release two new images. One of Charon, one of Pluto. The close up of Pluto shows mountains 3,500m high. Both images show a lack of craters meaning the landscape is relatively young in solar system terms. Certainly less than 100m years old which is young compared to the Earth at 4.5b years old!
This is an alternate universe where the Justice League use lethal force to maintain order on Earth. Batman, Superman and Wonder Woman are not who you are familiar with. An animated movie is expected at the end of the month and will shine an altogether darker light on these super heroes.
In an alternate universe, the Justice League is a brutal force that maintains order on Earth. Superman is named Hernan Guerra and is the son of General Zod, who was rocketed to Earth as a child and raised by a family of Mexican immigrants. Batman is Kirk Langstrom, a scientist who has inadvertently transformed himself into a vampire in an attempt to cure his cancer, feeding on criminals to satisfy his hunger. Wonder Woman is Bekka, who is the wife of the New God Orion. The Justice League’s unaccountability is ultimately challenged by the world’s governments following the suspicious deaths of renowned scientists. (Wikipedia)
There’s a series of comic books too. Here’s a sneak peek at the first Superman one. Looks great!
