NASA engineers are testing a revolutionary ultralight antenna made from aerogel—one of the lightest solid materials on Earth—to improve satellite communications for future aircraft, drones, and air taxis.

In a thrilling milestone for planetary science, NASA's Lucy spacecraft has successfully imaged asteroid Donaldjohanson, revealing intricate geological features and a surprising shape during its second asteroid flyby. The close encounter, which occurred on April 20, 2025, saw Lucy pass just 600 miles (960 km) from the asteroid, capturing detailed observations that may unlock secrets of our solar system's ancient past.

Just over a day after its launch, a SpaceX crew capsule successfully docked with the International Space Station (ISS) on Sunday. The mission delivered four replacement astronauts representing the US, Japan, and Russia to the station. These newcomers are scheduled to spend the next few days familiarising themselves with the ISS and its operations under the guidance of veteran astronauts Butch Wilmore and Suni Williams.

On March 14, 2025, a rare and dramatic celestial event captivated skywatchers across the globe. The lunar “blood moon” eclipse, a phenomenon where the Moon takes on a reddish hue, was visible across the Americas, parts of Europe, and in regions near the Pacific and Atlantic Oceans. This spectacle offered a rare opportunity for astronomers and stargazers to observe the intricacies of our solar system in action.

China’s Zhurong Rover has uncovered compelling evidence suggesting that Mars once had sandy beaches, further supporting the theory that an ancient ocean covered parts of the planet’s northern plains.

Mars, the Red Planet, has long captivated scientists and stargazers alike with its characteristic rusty hue. For years, the prevailing theory about this color has been that it is caused by iron minerals in the Martian surface that have rusted over billions of years, likely due to interactions with liquid water and oxygen in the atmosphere, a process similar to rusting on Earth. However, new research combining spacecraft observations and novel laboratory techniques suggests that our understanding of why Mars is red may need to be reconsidered.
