Watch Live Tuesday: 2 Rocket Launches and a Space Station Cargo Ship’s Departure

Today (Aug. 6) is going to be a big day in space!

After a Cygnus cargo spacecraft departs the International Space Station this afternoon, SpaceX and Arianespace will be launching a total of three new communications satellites into orbit. You can watch all three events live here at Space.com.

First, the Cygnus cargo ship will undock from the space station at 12:15 p.m. EDT (1615 GMT). NASA astronauts Nick Hague and Christina Koch will use the station’s Canadarm2 robotic arm to release the vessel into the vacuum of space. NASA TV will provide live coverage of the send-off beginning 15 minutes prior to its departure.

France Is Making Space-Based Anti-Satellite Laser Weapons

France will develop satellites armed with laser weapons, and will use the weapons against enemy satellites that threaten the country’s space forces. The announcement is just part of a gradual shift in acceptance of space-based weaponry as countries reliant on space for military operations in the air, on land, and at sea—as well as for economic purposes, bow to reality and accept space as a future battleground.

Propellantless propulsion system could keep satellites in orbit, reduce space junk

Circa 2018

One of the main factors limiting the life of satellites is how much propellant they can carry to execute orbital corrections. Now scientists in Spain have come up with a propellantless propulsion system that also doubles as an electric generator. Using the Earth’s magnetic field interacting with a 2-km long aluminum tether, the system could be used to dispose of space debris and boost the orbit of the International Space Station (ISS).

Princeton Unveils Plasma-Powered Satellite

Future satellites could make their way deeper into space than ever before thanks to a new plasma-fueled thruster.

The new thruster, built by engineers at the Princeton Plasma Physics Laboratory, could open up a whole new realm of scientific research, according to a Princeton press release. That’s because the thruster could finally give the tiny satellites called CubeSats the ability to move between the upper and lower bounds of orbit — a spectacular leap toward comprehensive orbital infrastructure.

It’s all CRUMBLING… NYC power outages to continue; GPS satellites fail; tech is collapsing at an increased rate

(Natural News) A series of incidents that have occurred in close proximity to each other over the past several days are leading many to believe that technology is failing society and that U.S. infrastructure is collapsing faster than previously believed.

On Saturday, a wide swath of Manhattan’s West Side was plunged into darkness for several hours, and the electric company officials responsible for providing the power — Con Edison — are not sure why the failure occurred.

As reported by the New York Post, the company said in a statement late Sunday morning that it “will be conducting a diligent and vigorous investigation to determine the root cause of the incident.”

Blockchain will make sure green pledges aren’t just greenwash: a new initiative

Blockchain will make sure green pledges aren’t just green wash.

When a country or a company makes a promise to reduce carbon emissions, respect fishing quotas or cut toxic output, how can we be sure they’ll keep their word?

The truth is, it’s often extremely hard. But a new initiative — Global Ledger — led by a group of World Economic Forum Young Global Leaders (YGLs) aims to change that.

Using data from a nearly-infinite array of observation devices — drones, cameras, nano-satellites and soon-to-be-ubiquitous Internet of Things applications — reliable and unbiased information can be gathered and then stored using blockchain technology, which ensures data is verified and almost impossible to manipulate.
