The global headcount is always increasing and we might crack the 8 billion mark as we speak. So the need for electricity is growing with it. Smaller nations like Costa Rica show us what can be done to transition from fossil fuels and go for renewables instead. Scaling up the combination of wind, solar or geothermal energy to satisfy the massive demand of electricity is hard, though, as recent history has shown us. Maybe it’s time to tap into more […]
Ever since the EM drive first made headlines, science lovers have puzzled over how the propulsion system seems to produce thrust, despite the fact it’s ‘impossible’ according to one of the most fundamental laws of physics – Newton’s third law of motion. Now a team of physicists have put forward an alternative explanation – it turns out the EM drive could actually work without breaking any scientific laws, if we factor in a weird and often overlooked idea in quantum […]
The concept of a human habitat in orbit around the moon came a step closer on September 27, when NASA and the Russian space agency (Roscosmos) signed up to a common vision for future human exploration. The project, a follow-up to the International Space Station (ISS), involves a facility placed in orbit somewhere between the Earth and the moon – a region known as cis-lunar space. A Lunar Space Station. Seen as a stepping-stone on the way to deeper space […]
The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-39-year journey since their 1977 launches, they each are much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between stars, filled with material ejected by the death of nearby stars millions of years ago. Scientists hope to learn more about this region when Voyager 2, in […]
Can we avoid international conflict in time while resolving the “law lag” of mining celestial resources? Ambiguous laws, created decades ago, could prevent us from taking full advantage of space resources through projects like asteroid mining and water generation for potential colonies. How Far Do Earth’s Treaties Extend Into the Universe? In 1967, the US, the UK, and what was then the Soviet Union signed the Outer Space Treaty (OST), the only law governing the activities of humankind in outer […]
The Voyager 1 spacecraft – humanity’s farthest journey – was launched in September 1977 and flew by Jupiter and Saturn before continuing on toward interstellar space, where it now continues it’s relentless journey out into the cosmos. After nearly 4o years, amazing scientific data, and nearly 21 billion kilometers, was Voyager worth it? What Do You Think?
Image: SpaceX Caption: Retro-thrusters could bring SpaceX’s unpiloted Red Dragon capsule gently down to the Martian surface. In 2018, SpaceX could become the first private company to land its own Dragon spacecraft on Mars. But it doesn’t plan to do so alone. NASA wants to see if SpaceX’s landing tech could put astronauts on Mars, and to find out, its vowed to help the private company send an uncrewed capsule to the Red Planet, Sarah Fecht reports in Popular Science. […]
NASA’s Juno Probe took the spectacular images recently as it made its first close pass of the planet since it went into orbit in July. Juno’s quest is to investigate the secrets of the Solar System by finding out more about its biggest planet – Jupiter. The spacecraft is currently flying around Jupiter on a course that takes 53 days to complete. JUPITER FACTS; Jupiter is 11 times wider than Earth and 300 times more massive It takes 12 Earth […]
