Reusable Rockets


Using rockets to launch into space is certainly nothing new. What is new is being able to use that same rocket again and again and the reduction in space flight expenses.

Blue Origin, a private space company, has managed to do exactly that. On November 24, 2015, they announced that after a successful rocket launch they have succeeded in landing the rocket back in a vertical position and in a gentle enough manner for it to be reusable for future launching.

"Named in honor of the first American in space, Alan Shepard, the New Shepard, vertical takeoff and vertical landing vehicle will carry six astronauts to altitudes beyond 100 kilometers, the internationally recognized boundary of space."

A Quantum Record

If you have been following our newsletter the past few years, you would know that any new technological and scientific development that might get humanity closer to any kind of Star Trek type transporter is cause for celebration here at "Be The Change".

This month, Researchers from Stanford announced that they have advanced the quantum physics problem of how to send entangled particles over long distances. Even Albert Einstein described the quantum entanglement of two or more particles over a distance as "spooky action."

Nevertheless, the researchers at Stanford have used photons to communicate between two electrons through more than a mile of fiber optic cable which is an important step toward proving the practicality of quantum networks. Scientists and engineers are especially interested in the practical application of this technology to make quantum networks that can send highly secure information over long distances.

A Hairy Solar System




Dark Matter is an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe. The regular matter, which makes up everything we can see around us, is only 5 percent of the universe. The rest is dark energy, a strange phenomenon associated with the acceleration of our expanding universe.

Neither dark matter nor dark energy has ever been directly detected. However, based on many observations of its gravitational pull in action, scientists are certain that dark matter exists, and have measured how much of it there is in the universe.

According to dark matter theories, galaxies with stars made of ordinary matter form because of fluctuations in the density of dark matter. Gravity acts as the glue that holds both the ordinary and dark matter together in galaxies. Based on calculations done in the 1990s and simulations performed in the last decade, dark matter forms "fine-grained streams" of particles that move at the same velocity and orbit galaxies such as ours.

But what happens when one of these streams approaches a planet such as Earth? Gary Prezeau of NASA's Jet Propulsion Laboratory, Pasadena, CA, has used computer simulations to find out.

His analysis finds that when a dark matter stream goes through a planet, the stream particles focus into an ultra-dense filament, or "hair," of dark matter. In fact, thee should be many such hairs sprouting from Earth. According to these simulations, Earth's gravity would focus and bend the stream of dark matter particles into a narrow, dense hair.

This is a very significant theory because if scientists could pinpoint the location of the root of these hairs, they could potentially send a probe there and get a treasure trove of unprecedented data about dark matter.
