Future of Virtual Reality Series Launches Today

Posted by in categories: neuroscience, space, space travel, virtual reality

If you’ve ever watched someone experience virtual reality for the first time, you know it can involve screaming, flapping arms, and occasional falls.

On one level people know their bodies are safe on the stable chair, but as their minds are catapulted through outer space on a spaceship to Mars or beamed into a refugee camp in Syria —they can’t help but lose their grip on reality and go along for the ride.

In fact, our brains don’t even require photorealism for suspension of disbelief in VR. A choppy CGI rendition will cause our heart rates to increase and our palms to get sweaty when we’re riding a virtual roller coaster or standing on the edge of a virtual building looking at the ground 30 stories below.

Company in Canada gets U.S. patent for space elevator

Posted by in categories: energy, space, virtual reality

Exploring space while seated on Earth, gazing up on screens in museum theaters or at home via VR headsets. is exciting but the top imagination-grabber is the very idea of finding a way to access space. This is the present-day realm of creative thinking over space elevators, in the use of a giant tower to carry us to space.

Scientists working on space elevators are thinking about materials and designs that can be used to access space as an alternative to rocket technology. A sign of the times is the upcoming Space Elevator Conference 2015 which takes place this month in Seattle.

Imagine, said The Spaceward Foundation, the , serving as a track on which electric vehicles called “climbers” can travel up and down carrying about 10 tons of payload.“There are no intense gravity-loads during the trip, no acoustic vibration, no onboard fuel, nor any of the rest of the drama (and cost) associated with rocket launches,” it added.

3D Printing in the Vacuum of Space Now Possible from Made In Space

Posted by in categories: 3D printing, space

At the end of last year, Made In Space made what was a huge achievement for 3D printing in space by sending their Zero G 3D printer, capable of 3D printing without gravity, to the International Space Station. There, it has 3D printed numerous components, including a now famous wrench and twenty-three other prints that have since returned to Earth for lab analysis. The ability to 3D print without gravity restraints will allow those aboard the ISS to 3D print tools and parts using raw material, preventing the need for direct shipments of such objects from Earth. This ability is an exciting one, but the true goal of NASA and Made In Space has been to 3D print in vacuum of space itself. Today, Made In Space has announced that such a feat has now been proven possible through a series of tests performed here on Earth.

Slow death of Universe confirmed with precision

  • The universe radiates only half as much energy as 2 billion years ago
  • New findings establish cosmos’ decline with unprecedented precision


From CNN
—The universe came in with the biggest bang ever. But now, with a drooping fizzle, it is in its swan song. The conclusion of a new astronomical study pulls no punches on this: “The Universe is slowly dying,” it reads.

Astronomers have believed as much for years, but the new findings establish the cosmos’ decline with unprecedented precision. An international team of 100 scientists used data from the world’s most powerful telescopes — based on land and in space — to study energy coming from more than 200,000 galaxies in a large sliver of the observable universe. [Full story below or at CNN.com]…

Based on those observations, they have confirmed the cosmos is radiating only half as much energy as it was 2 billion years ago. The astronomers published their study on Monday on the website of the European Southern Observatory.

Analysis across many wavelengths shows the universe's electromagnetic energy output is dropping.The team checked the energy across a broad spectrum of lightwaves and other electromagnetic radiation and says it is fading through all wavelengths, from ultraviolet to far infrared.

Watch the Moon cross in front of the Earth, as seen from a million miles away

Posted by in category: space

A thing of beauty!


We all need a little cosmic perspective from time to time, and this is as good as it gets. NASA has released this truly stunning GIF of the Moon passing in front of the Earth. The image sequence offers an unprecedented look at the relationship between the two planetary objects, and also gives a detailed look at the rarely seen far side of the Moon.

The resulting GIF is so amazing that it’s almost unbelievable, but the images are completely real. The whole sequence was taken by the Earth Polychromatic Imaging Camera (or “EPIC,” a wonderfully appropriate acronym) on the DSCOVR satellite that was launched in February.

From the Earth to the Moon: 1865/1968

Posted by in categories: alien life, astronomy, space, space travel

How does science fiction become science fact? Often the link between art and science can be hard to pin down. It can be unclear if science fiction is actually influencing science or merely observing it, giving the public sneak peaks into the implications of scientist’s work.

But some work of science fiction create direct links to the future. As a young man in Russia, Konstantin Tsiolkovsky read a translation of Jules Verne’s ‘From the Earth to the Moon.” And although Verne’s plan to get to the moon wouldn’t have worked, the novel had just enough science mixed in with its romance to make the central idea seem plausible. Tsiolkovsky became obsessed with the idea of spaceflight, and his life’s work created the foundations of modern rocketry.

One hundred years after Verne wrote his novel, a group of individuals who had been inspired by Verne’s fantasy as children launched a voyage to the moon.

Astronomers find star with three super-Earths

Posted by in category: space

Astronomers said Thursday they had found a planetary system with three super-Earths orbiting a bright, dwarf star — one of them likely a volcanic world of molten rock. The four-planet system had been hiding out in the M-shaped, northern hemisphere constellation Cassiopeia, “just” 21 light years from Earth, a team reported in the journal Astronomy & Astrophysics. Super-Earths have a mass higher than Earth’s but are lighter than gas giants like Neptune, Saturn or Jupiter. They can be made of gas, rock, or both.

NASA’s Curiosity Rover Eyes Weird Rock On Mars

Posted by in category: space

NASA’s Mars rover Curiosity went out of its way to investigate a rock the likes of which it has never seen before on the Red Planet. Measurements by Curiosity’s rock-zapping ChemCam laser and another instrument revealed that the target, a chunk of bedrock dubbed Elk, contains high levels of silica and hydrogen, NASA officials said. “One never knows what to expect on Mars, but the Elk target was interesting enough to go back and investigate,” ChemCam principal investigator Roger Wiens, of Los Alamos National Laboratory in New Mexico, said in a statement.
