Late last month NASA shared what its now-defunct InSight lander found out about the Red Planet's insides. In a study published in Science researchers reported on data from the seismometer that InSight placed on Mars's surface in 2018. By 2022, when the mission ended, the seismometer had recorded more than 1,300 marsquakes. Because a quake's seismic waves behave differently based on what kinds of material they're passing through, the shake-ups allowed scientists to study the planet's core, mantle and crust.

In 1877, Giovanni Schiaparelli, an Italian astronomer (and uncle of the fashion icon Elsa), started making a map of the surface of Mars, which was then at one of the closest points to Earth in its orbit. Schiaparelli was color-blind, but this affliction may have increased his ability to see geometric outlines, and what he observed on Mars was extraordinary: not only shapes that resembled oceans but long, straight lines between them.

Talk about fake news: In 1907 a New York Times banner headline declared, "There Is Life On the Planet Mars." Upping the ante the next year, the stodgy Wall Street Journal claimed "proof" of "conscious, intelligent human life" on our red neighbor. The idea of life on other planets had been orbiting the public imagination ever since the realization that the Earth wasn't alone in the solar system.

The true extent of this alien craze escaped my attention and on almost every single page, there was something to which I mumbled, "Wow, I didn't know that." Among the many well-deserved accolades about David's book is, " The Martians is ... a fizzing terrific read." (Mary Roach, author of Packing for Mars) In fact, it is far more than that.

The new centimeter-wide disks are made from two thin perforated membranes of ceramic alumina connected by tiny vertical supports. They are kept aloft by a force called photophoresis: the light-induced movement of small particles at very low atmospheric pressures. In lab experiments simulating mesospheric air pressure and illumination, the researchers showed that their devices could float passively, without any power source. Their paper reporting the results was published in Nature on August 13.

Researchers discovered evidence of a 1.6-million-year cycle affecting Earth and Mars climate patterns from Jurassic lake sediments in the Sangonghe Formation, China.

Thousands of miles of ancient riverbeds have been discovered in the southern highlands of Mars, indicating the planet was once much wetter than previously believed.

"By acquiring Kellanova, Mars will add several very popular brands of potato chips and cereals to its already broad and strong product portfolio," said EU competition chief Teresa Ribera.

When it comes to building brands, we know that to remain iconic, we must remain in motion," said Gülens Bengi, lead chief marketing officer at Mars and chief growth officer at Mars Snacking. It speaks to the need for brands to innovate continuously.

The architects pose significant questions about interplanetary migration: 'Companies are actively developing rocket-based transportation systems, some with the goal of moving a million people to Mars. But where will they live?'

To be tagged as a space watch, a timepiece must remain accurate even without gravity and withstand NASA's rigorous testing for space missions.

Deimos, the smaller of Mars' two moons, has been overlooked in favor of Phobos, but scientists envision potential uses for this tiny celestial body.

Our study is the first to demonstrate that the metabolism of the fungal partner in lichen symbiosis was active while being in a Mars-like environment.

During his address to Congress, President Trump emphasized America’s aim to plant the Stars and Stripes on Mars, likening it to Manifest Destiny.
