Scientists study a Martian meteorite with a little help from 3D printing
Posted by Karen Hurst in categories: 3D printing, space
A 3D-printing company is aiding NASA by using its additive manufacturing technology to create an accurate replica of a meteorite located 34 million miles from Earth.
Measuring approximately 2 feet in length, the meteorite known as Block Island was first discovered on Mars by the Exploration Rover Opportunity in 2009. Studying it is an important part of furthering our knowledge about Mars and other planets, but at present the prospect of bringing it to Earth to examine u close is out of the question.
Fortunately, the Mars rover was able to take images and measurements to transmit back home, and this data has now been used by Mcor Technologies, an Ireland-based 3D-printing company, to create a life-size Block Island model.

NASA just detected high-energy X-rays in space that don’t come from any known source
Posted by Shane Hinshaw in categories: energy, space
A NASA-funded study has solved a longstanding mystery over the origin of X-rays that permeate space in our Solar System, but in doing so, it’s also discovered an entire group of high-energy X-rays that can’t be explained.
The research comes from a new analysis of data recorded by NASA’s DXL rocket mission, which took flight in 2012 to settle the question of what creates these low-energy X-ray emissions – called the diffuse soft X-ray background – in our corner of the galaxy.
At the time, there were two central hypotheses. X-ray emissions were known to come from solar wind, but scientists also thought they might originate from what’s called the Local Hot Bubble – a theorised region of hot gas that envelops our Solar System. But which was correct?

Kardashev Scale: What It’ll Be Like When We Harness the Power of an Entire Galaxy
Posted by Andreas Matt in categories: energy, space
According to the Kardashev scale, a Type III civilization is a society that has managed to harness (and control) the energy output of a galaxy. Here’s what that means.
To measure the level of a civilization’s advancement, the Kardashev scale focuses on the amount of energy that a civilization is able to harness. Obviously, the amount of power available to a civilization is linked to how widespread the civilization is (you can’t harness the power of a star if you are confined to your home planet, and you certainly can’t harness the power of a galaxy if you can’t even get out of your solar system).

Pluto’s Liquid Water Ocean Might Be Insanely Deep
Posted by Sean Brazell in category: space
In recent months, there’s been growing evidence that Pluto is hiding a liquid water ocean beneath its frozen surface. New models by researchers at Brown University support this hypothesis, and take it one mind-boggling step further: Pluto’s ocean may be more than 100 kilometers (62 miles) deep.
