China plans to launch an ‘artificial moon’ to light up the night skies

November 10th, 2018 at 11:02 am » Comments Off

The night skies might soon have company: Chinese scientists are planning to launch an artificial moon into orbit by 2020 to illuminate city streets after dark. Scientists are hoping to hang the man-made moon above the city of Chengdu, the capital of China’s southwestern Sichuan province, according to a report in Chinese state media. The […]



Reaction Pre-cooled Engines could deliver reusable hypersonic planes by 2025

November 6th, 2018 at 11:20 am » Comments Off

Reaction Engines of the UK could be part of a winning group of bidders for open-ended hypersonic weapons development. They have proven an innovative pre-cooling system which does not require the development of new materials to handle the heat of hypersonic flight speeds. The US Air Force Research Labs are already working with them. They […]



Carbon dioxide fertilization greening earth, study finds

October 27th, 2018 at 10:19 am » Comments Off

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25. An international team of 32 authors from 24 institutions in eight countries led […]



Jeff Bezos predicts we’ll have 1 trillion humans in the solar system, and Blue Origin wants to help get us there

Blue Origin’s aim is to lower the cost of access to space, Jeff Bezos said during a surprise appearance at Wired’s 25th anniversary conference. Amazon and Blue Origin founder Jeff Bezos provides the keynote address at the Air Force Association’s Annual Air, Space & Cyber Conference in Oxen Hill, MD, on September 19, 2018. Blue […]



This crazy ambitious timeline shows when and how Elon Musk and Space X plan to colonize Mars

October 25th, 2018 at 10:40 am » Comments Off

Elon Musk is hell-bent on colonizing Mars. That’s the spirit with which he founded SpaceX, his rocket company, in 2002. Musk was frustrated that NASA wasn’t doing more to get people to the red planet – and concerned a backup plan for humanity wasn’t being developed (for when Earth becomes an uninhabitable wasteland). Since then, […]



Japan just became the first country to deploy rovers on an asteroid

September 28th, 2018 at 11:16 am » Comments Off

The Hayabusa 2 mission is visiting an asteroid 200 million miles from Earth to collect samples. The mission profile involves a lot of robots, bullets, and explosives. In 2014, the Japanese Aerospace Exploration Agency (JAXA) launched the Hayabusa 2 spacecraft on a four year journey to Ryugu, an asteroid nearly 200 million miles from Earth. […]



A revolutionary new space launch idea: Introducing The Pythagoras Sling

September 14th, 2018 at 9:50 am » Comments Off

The Pythagoras Sling uses a lengthy graphene string pulled via two hoops suspended from simple parachutes to rapidly accelerate a projectile into orbit. Graphene string will likely become widely available over the next two decades. If it works as expected, the Pythagoras Sling launch system could greatly reduce the cost of getting into space compared […]



Can we get into space without big rockets?

September 4th, 2018 at 9:54 am » Comments Off

Since humans began putting satellites into orbit in the 1950s, we’ve relied upon big, powerful rockets to escape Earth’s gravity and get into space. But big rockets have a major downside, in that they make space launches expensive. Case in point: NASA’s Space Launch System heavy lift rocket, which is scheduled for its maiden flight […]



Want a future-proof degree? Head to Colorado for asteroid mining

Are you a high schooler wondering what career to pursue that won’t be gobbled up by robots in the next few years? Are you an engineering grad, economist, physicist, or policy analyst looking to become an expert in a new, but fast-developing discipline? If so, the Colorado School of Mines has the perfect answer for […]



This astrophysicist explains the surprisingly complex concept of ‘nothing’

August 27th, 2018 at 10:18 am » Comments Off

Philosophers have debated the nature of “nothing” for thousands of years, but what has modern science got to say about it? In an interview with The Conversation, Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, explains that when physicists talk about nothing, they mean empty space (vacuum).
