Boeing has announced that the ABS–3A, the world’s first all-electric propulsion satellite, has commenced its tour of duty.

The communications satellite is being operated by ABS, a Bermuda-based satellite network that provides TV, Internet, and cellular services across the world. Unlike conventional satellites, which have mostly used propellant systems that burn chemicals of one kind or another to get about the place, the ABS–3A makes use of a xenon-ion propulsion system to achieve thrust.

Specifically, the all-electric propulsion system uses electron bombardment to create xenon ions, which are then expelled by the spacecraft, producing thrust in the opposite direction.

We’ve known there is water on Enceladus for a while now, but NASA has just confirmed a more recent theory about the icy moon of Saturn: it has a subsurface ocean that spans the entire globe. The news comes just a handful of months after the agency discovered evidence of hydrothermal vents, which are believed to be integral to the formation of life here on Earth.

The confirmation was made using research from Cassini — a spacecraft that arrived at Saturn in 2004 and has spent the last decade studying the planet and its many moons. (It was launched in 1997.) The researchers used Cassini to measure the wobble in Enceladus’ orbit of Saturn, something that “can only be accounted for if its outer ice shell is not frozen solid to its interior.”

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.

Dr Michael Fossel is a PhD and MD heading up telomerase research and therapy and has kindly written a blog article for Bioviva detailing the work both they and his company Telocyte are doing to fight back against Alzheimer’s.

How Alzheimer’s Can Be Prevented and Cured…

Michael Fossel, MD, PhD

As I said in my medical textbook on aging, “If age is a thief, then the greatest treasure we lose is ourselves.” We fear Alzheimer’s not simply because it takes away our health, but because it steals our souls.

Once, we thought it was simply “old age” that gradually killed the cells that carry information and memory. These are brain cells that make us who we are and define our consciousness.

Only in the past two decades, have we gradually come to realize that it’s not the neurons, which are merely the innocent bystanders in the tragedy,

but the microglial cells that cause the disease. It’s our microglia, not our neurons that steal our very souls.

Elon Musk has officially requested permission from the Federal Communications Commission (FCC) to launch a 4000 strong flotilla of satellites into orbit.

Elon Musk’s space company ‘SpaceX’ announced their primary plans in January with the official request coming early last week. If all goes to plan the satellites could be in orbit and the Internet operational within five years.

While satellite internet is not new technology, SpaceX plans to reduce the enormous latency over a space connection by launching the satellites into a low Earth orbit at around 650km. The low orbit and slower speeds mean 4000 satellites are needed to cover the earth, far more than necessary for higher orbit networking.

The 1st Space Development Network Conference will be held in Bangalore in January, 2016. The motivation of the conference is to invite researchers, eminent scientists, faculty from reputed colleges and students working in the area of Space development and technology to present their research and get valuable feedback from the people attending the conference. The topics of space development network conference are given below:

•Asteroid Mining.

•Space Colonization.

•Space Debris.

•Satellites and Cubesats payload.

The man-made “plant” can create endless oxygen using light and water!

Pioneers have been dreaming about living in outer space for eons, but there’s always been one major roadblock: securing a long-term oxygen supply. Toting around an indefinite supply of O2 isn’t feasible, and obtaining oxygen from plants in space is difficult, as green vegetation does not thrive in zero gravity environments.

But thanks to graduate student Julian Melchiorri, long-term space travel could soon be a reality. Melchiorri worked with Dezeen and MINI Frontiers to produce the Silk Leaf, an invention capable of sustaining life.
