Lasting 51.9 seconds, Ingenuity’s experimental flight on April 22, 2021, added several new challenges to its first flight, including a higher maximum...
Mars had drier and wetter eras before drying up completely in the Hesperian period, about 3 billion years ago, according to an analysis of observational...
On April 19, 2021, NASA’s Ingenuity helicopter made history, hovering above Jezero Crater on Mars, demonstrating that powered, controlled flight on another...
Given the current trends in Bitcoin mining, Chinese researchers estimate that the energy consumption from this process in their country alone will peak...
Using data from the Atacama Large Millimeter/Submillimeter Array (ALMA), astronomers from India have detected acetone, disulfur monoxide, and carbon monoxide...
Oxygen levels fluctuated dramatically for about 200 million years after the start of the Great Oxidation Event, with permanent atmospheric oxygenation...
A new study published in the Journal of Geophysical Research: Planets is a first step toward a generalized theory of how precipitation and condensible...
