Rocket Launches May Be Polluting Our Atmosphere in New Ways

Rocket Launches May Be Polluting Our Atmosphere in New Ways

SpaceX, Blue Origin, and a host of other private companies helped to make 2021 the year with the most space launches in history, but scientists say this mad dash to space could be causing further damage to our atmosphere. The number of launch attempts has lined in the last decade. And after counting all of … Read more

Mystery issue experienced on NASA’s Voyager 1 probe from 1977

Mystery issue experienced on NASA's Voyager 1 probe from 1977

Voyager 1 continues to operate well, despite its advanced age and 14.5 billion-mile distance (23.3 billion kilometers) from Earth. And it can receive and execute commands sent from NASA, as well as gather and send back science data. But the readouts from the attitude articulation and control system, which control the spacecraft’s orientation in space, … Read more

The Power of Fusion Energy Might Finally Be Unlocked Thanks to a New Physics Update

The Power of Fusion Energy Might Finally Be Unlocked Thanks to a New Physics Update

In the world of renewable energy, there’s perhaps no more ambitious goal than fusion power. This involves fusing hydrogen atoms to create helium—a process that generates an ungodly amount of energy as a result. It’s a reaction that occurs every single moment in the sun, but replicating it on Earth is a much rarer and … Read more

Boeing tries to catch up to SpaceX after plenty of drama

Boeing tries to catch up to SpaceX after plenty of drama

New York CNN Business — Boeing is the world’s largest aerospace company, a primary US defense contractor, and a titan of a global aviation duopoly. A few years ago, the idea that it would dominate commercial space was a given, and companies like SpaceX, a relatively young business relying on a strategy of moving fast … Read more

New Kind of ‘Solar’ Cell Shows We Can Generate Electricity Even at Night

New Kind of 'Solar' Cell Shows We Can Generate Electricity Even at Night

Conventional solar technology soaks up rays of incoming sunlight to bump out a voltage. Strange as it seems, some materials are capable of running in reverse, producing power as they radiate heat back into the cold night sky. A team of engineers in Australia has now demonstrated the theory in action, using the kind of … Read more

Physicists figured out how launching a Falcon 9 changes the atmosphere

Physicists figured out how launching a Falcon 9 changes the atmosphere

With the cost of launching a rocket into space falling, the number of rocket launches is, well, taking off. Last year, governments and companies across the world successfully launched 133 rockets into orbit, breaking a record that stood for 45 years. But there’s a catch. Breaking free from Earth’s gravity requires a rocket to release … Read more

Solar Orbiter spies a ‘hedgehog’ during close pass of the sun

Solar Orbiter spies a 'hedgehog' during close pass of the sun

The spacecraft, which flew by the sun on March 26, has returned a treasure trove of new images and insights after coming within one-third the distance from the sun to the Earth. Solar Orbiter’s heat shield reached about 932 degrees Fahrenheit (500 degrees Celsius), but functioned as expected and protected the spacecraft during its historic … Read more
