What Happens If China Makes First Contact?

Posted by in categories: alien life, satellites

As America has turned away from searching for extraterrestrial intelligence, China has built the world’s largest radio dish for precisely that purpose.

Last January, the Chinese Academy of Sciences invited Liu Cixin, China’s preeminent science-fiction writer, to visit its new state-of-the-art radio dish in the country’s southwest. Almost twice as wide as the dish at America’s Arecibo Observatory, in the Puerto Rican jungle, the new Chinese dish is the largest in the world, if not the universe. Though it is sensitive enough to detect spy satellites even when they’re not broadcasting, its main uses will be scientific, including an unusual one: The dish is Earth’s first flagship observatory custom-built to listen for a message from an extraterrestrial intelligence. If such a sign comes down from the heavens during the next decade, China may well hear it first.

The Future May Owe Itself to Blockchain Technology. Here’s Why

Posted by in categories: bitcoin, computing, economics, internet, satellites

Sending satellites into space is going to continue to get cheaper since SpaceX proved it could reliably launch refurbished rockets. This is going to open up space exploration to more entities allowing for the continued democratization of space. Other technological advances could make a global space centered sharing economy a real possibility.

The rise of the internet and the ubiquity of mobile computing devices have changed everything from travel and shopping to politics – think Uber, Amazon, and Twitter.

General Atomics ramping cubesat production, muses railgun smallsat launcher

Posted by in categories: drones, military, satellites

WASHINGTON — General Atomics is better known for building Predator combat drones and mining uranium than building spacecraft, but that could change as the company develops an interest in building defense-focused cubesats.

Also in the realm of possibility: using expertise from building railguns to design a large, electromagnetic cannon as a means to orbit small satellites.

Nick Bucci, vice president of missile defense and space systems for General Atomic’s Electromagnetic Systems Group, said the company has built 11 cubesats for the U.S. Army over the past seven years, and is gradually becoming more and more invested in space.

Spacewalk 360: RT releases first-ever panoramic video of man in outer space (VIDEO)

Posted by in category: satellites

RT has released the first-ever 360-degree footage shot by man in outer space, putting viewers in the shoes of two Russian cosmonauts launching nanosatellites from outside the International Space Station (ISS).

The video, which shows out-of-this-world views of Planet Earth, is the first time that the so-called extravehicular activity (EVA) has been filmed in 360. The immersive new format previously helped viewers explore the ISS modules as part of the Space 360 project.

Pence Pledges the U.S. Will Go to the Moon, Mars and Beyond

Posted by in categories: government, military, policy, satellites, space

Washington (AP) — Seated before the grounded space shuttle Discovery, a constellation of Trump administration officials used soaring rhetoric to vow to send Americans back to the moon and then on to Mars.

After voicing celestial aspirations, top officials moved to what National Intelligence Director Dan Coats called “a dark side” to space policy. Coats, Vice President Mike Pence, other top officials and outside space experts said the United States has to counter and perhaps match potential enemies’ ability to target U.S. satellites.

Pence, several cabinet secretaries and White House advisers gathered in the shadow of the shuttle at the Smithsonian Institution’s Steven F. Udvar-Hazy Center to chart a new path in space — government, commercial and military — for the country. It was the first meeting of the National Space Council, revived after it was disbanded in 1993.

An Earth-Sized Space Shield to Protect Us From Solar Storms Is Less Crazy Than It Sounds

Posted by in categories: economics, particle physics, satellites

Every 100 years or so, our Sun gives off a great big belch that sends an intense wave of charged particles towards Earth. This wasn’t a problem in the past, but our high-tech civilization is now disturbingly vulnerable to these solar storms. A new study quantifies the economic risks posed by these extreme solar storms, while also proposing a super-futuristic solution to the problem: an Earth-sized shield built in outer space.

The term “solar storm” is used to identify the various nasties the Sun can hurl our way, including x-rays, charged particles, and magnetized plasma. In 1859, a series of powerful coronal mass ejections (CMEs) hit our planet head on, disrupting telegraph stations and causing widespread communication outages. If we were to be hit by an equally powerful solar storm today, it would knock out satellites and electrical grids, disrupting global communications, transportation, and supply chains. Total worldwide losses could reach up to $10 trillion, with recovery taking many years.
