Researchers at Kyushu University have found that Japan's current policy of stopping the sale of gas vehicles by 2035 and transitioning only to hybrids and electric vehicles may be insufficient to reduce the country's CO2 emissions and prevent it from reaching its decarbonization target goals. In fact, emissions may temporarily increase.
The team's analysis showed that along with the policy

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep Space Network (DSN), which communicate with spacecraft via radio waves, to be retrofitted for optical, or laser, communications.
By packing more data into transmissions,

Satellite Laser Ranging (SLR) is a very precise, laser-based method for determining the distance between a satellite and Earth with an accuracy of a few millimetres. SLR is primarily used in geodesy. This is because the precise measurement of satellite orbits helps to determine changes in Earth's structure and rotation. The SLR method also makes important contributions in the field of satellite

It's a scenario made famous by the 1998 film 'Armageddon': an asteroid is spotted on a collision course with Earth, and experts scramble to plan a space mission to rendezvous with the asteroid and mitigate the danger. It's classic science fiction, but did you know there is a very real group responsible for recommending such a response in real life? And it celebrates its tenth birthday this week.
