When the Artemis 1 mission was launched in November, it became the world’s most powerful rocket, and with liftoff came a loud roar heard miles away. In JASA Express Letters, researchers report noise measurements during the launch at different locations around Kennedy Space Center. The data collected can be used to validate existing noise prediction models, which are needed to protect equipment as well as the surrounding environment and community. These data will be useful as more powerful lift vehicles are developed.
With its high-carbon footprint, air travel challenges the goal set by many countries of stabilizing global mean temperature by the middle of the 21st century. The aviation sector could achieve net-zero carbon emissions by 2050 through a combination of technology and a change in habits, but it’s not going to be easy, according to Earth system scientists at the University of California, Irvine.
Allocating passenger aircraft emissions using airfares rather than travel class would give a more accurate idea of individual contributions, finds a study led by UCL.
When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it, creating a hot, dense plasma. To protect against damage, spacecraft are typically covered by a heat shield material. Scientists for the first time used a tokamak to study what happens to these materials in a hot plasma. The research creates a path to improving heat shield materials for future planetary exploration.
