This is how the solar system is actually moving as it traverses the galaxy.
WaitYeah it’s not circular as you’ve been taught. It does revolve around the sun, but like every other star, the sun travels, and pulls us too. Fih-boe-nah-chi
and just where the fuck are we going
and why are we in this handbasket
JUPITER. Holy fuck
What about if Earth had rings?
What would that look like
this is like porn i love space

India’s Mars Satellite Arrives at Mars in One of the Cheapest Mars Missions Yet
Mangalyaan, which is Hindu for Mars craft, was launched in November of 2013. Last Wednesday (September 23, 2014), it entered Mars’ orbit and is one of the cheapest missions to Mars yet, costing only $74 million, even less than the $100 million budget to make the movie Gravity.
One factor contributing to the low price is the fact that they launched the spacecraft into Earth orbit and then boosted it from there to Mars once it had enough speed, eliminating the need to build a brand new heavy lift rocket. Another reason is that staff members for India’s space agency are paid lower salaries compared to that of other space agencies around the world.
This also marks the first time a country has succeeded on its first attempt at getting a spacecraft to Mars. Mangalyaan will now start researching methane deposits on the surface and how they are produced. There are only two ways in which methane is produced naturally here on Earth: through seismic activity and through life processes.
As one of the lowest cost missions to Mars to date, this is an important milestone in the history of space exploration. One of the biggest hurdles to space exploration right now is its huge price tag, so missions like this will inspire others to follow in Mangalyaan’s steps. It’s also a huge boon to India’s domestic space program; the fact that it can be done with less money than a Hollywood blockbuster shows just how much potential there is for the future. Combined with NASA’s MAVEN spacecraft, which arrived at around the same time, and other spacecrafts currently operating on and around Mars, Mangalyaan will provide more knowledge and insight about natural conditions on Mars.

Scientists from MIT have designed a next-generation spacesuit that acts practically as a second skin, and could revolutionize the way future astronauts travel into space. (Photo : Jose-Luis Olivares/MIT)
Astronauts are used to climbing into conventional bulky, gas-pressurized spacesuits, but this new design could allow them to travel in style. Soon they may don a lightweight, skintight and stretchy garment lined with tiny, muscle-like coils. Essentially the new suit acts like a giant piece of shrink-wrap, in which the coils contract and tighten when plugged into a power supply, thereby creating a “second skin.”
"With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space," lead researcher Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, said in astatement.
"We want to achieve that same pressurization, but through mechanical counterpressure - applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials. … Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration."
Newman, who has worked for the past decade on a design for the next-generation spacesuit, describes the new garment in detail in the journal IEEE/ASME: Transactions on Mechatronics.
The MIT BioSuit’s coils, which are a main feature of the outfit, are made from a shape-memory alloy (SMA). At a certain temperature, the material can “remember” and spring back to its engineered shape after being bent or misshapen.
Skintight suits are not a novel idea, but in the past scientists have always struggled with the question: how do you get in and out of a suit that is so tight? That’s where the SMAs come in, allowing the suit to contract only when heated, and subsequently stretched back to a looser shape when cooled.
Though the lightweight suit may not seem at first like it can withstand the harsh environment that is outer space, Newman and his colleagues are sure that the BioSuit would not only give astronauts much more freedom during planetary exploration, but it would also fully support these space explorers.
Newman and his team are not only working on how to keep the suit tight for long periods of time, but also believe their design could be applied to other attires, such as athletic wear or military uniforms.
"An integrated suit is exciting to think about to enhance human performance," Newman added. "We’re trying to keep our astronauts alive, safe, and mobile, but these designs are not just for use in space."
Scuse you, Dava Newman is a FEMALE professor at MIT.
(fyi, I passed out in a vacuum chamber wearing an earlier version of this suit. =D)
Tried to take photos of the lunar eclipse last week - failed miserably.
