The helicopter has been scouting the red planet for over a year.

NASA’s Ingenuity helicopter went from being a proof of concept for off-world flight to becoming a fully-fledged aerial scout for NASA’s Perseverance mission.

The helicopter wasn’t alone, as per a blog post from NASA. Images from the chopper show a flowing debris object, resembling a piece of a plastic bag, for part of its journey.

New underwater camera could help scientists explore unknown regions of the ocean, track pollution, or monitor the effects of climate change.

More than 95 percent of Earth’s oceans have never been observed, according to estimates by scientists, which means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Mars.

Mars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.

Is the future of humanity in space or on multiple planets?

You can’t build massive space habitats without harvesting resources from nearby asteroids. The resources of the Moon and asteroids are needed to create their proposed habitats.

The prospects for colonization of other planetary surfaces are unappealing.

Drink the forbidden seltzer.

Asteroid Ryugu has some dangerous seltzer for you, according to recent analysis by Japanese scientists on samples returned from JAXA’s Hayabusa2.

The underground ocean of Saturn’s moon Enceladus may contain significant amounts of phosphorus, which is vital for life as we know it.

NASA’s Juno spacecraft skimmed close above the surface of icy Europa Thursday (Sept. 29), capturing a view of the crust that is just the start of our new study of this ocean world.

Our position in the Milky Way makes it difficult for Earth to be detected using photometric microlensing.

Physicists at the Princeton Plasma Physics Laboratory (PPPL) have proposed that the formation of “hills and valleys” in magnetic field lines could be the source of sudden collapses of heat ahead of disruptions that can damage doughnut-shaped tokamak fusion facilities. Their discovery could help overcome a critical challenge facing such facilities.

The research, published in a Physics of Plasmas paper in July, traced the collapse to the 3D disordering of the strong magnetic fields used to contain the hot, charged plasma gas. “We proposed a novel way to understand the [disordered] field lines, which was usually ignored or poorly modelled in the previous studies,” said Min-Gu Yoo, a post-doctoral researcher at PPPL and lead author of the paper.

Fusion is the process that powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy. Capturing the process on Earth could create a clean, carbon-free and almost inexhaustible source of power to generate electricity, but comes with many engineering challenges: in stars, massive gravitational forces create the right conditions for fusion. On Earth those conditions are much harder to achieve.

The ensemble of sounds in this video captured on Mars by NASA’s Perseverance rover includes a dust removal tool for rock analysis, the Ingenuity Mars helicopter, and the impact of a laser on rocks. A new study of some of those sounds, captured mostly by the rover’s SuperCam microphone during the first 216 Martian days of the mission, reveals how sound differs on Mars, including traveling slower than on Earth.

A new study based on recordings made by the rover finds that the speed of sound is slower on the Red Planet than on Earth and that, mostly, a deep silence prevails.
