Bound NASA instrument preparing to brave the harsh atmosphere

Posted by in categories: chemistry, space

NASA scientists are preparing to paint the most detailed picture to date of the atmosphere of Venus when the aptly named DAVINCI — or Deep Atmosphere Venus Investigation of Noble Gases, Chemistry, and Imaging — mission drops a probe to the planet’s surface.

When the 3-foot-wide (0.9 meters) descent sphere of the DAVINCI mission takes its one-way parachute trip to Venus’ surface in the early 2030s, it will be carrying the VASI (Venus Atmospheric Structure Investigation) instrument along with five other instruments. VASI will collect data regarding the temperature, pressure and winds of Venus’ atmosphere as it makes its hellish descent and enters the planet’s crushing lower atmosphere.

‘Conan the Bacterium’ Has What It Takes to Survive on Mars

Posted by in categories: futurism, space

“If Martian life ever existed, even if viable lifeforms are not now present on Mars, their macromolecules and viruses would survive much, much longer,” says study lead author Michael Daly, a pathologist at Uniformed Services University of the Health Sciences, in a statement. “That strengthens the probability that, if life ever evolved on Mars, this will be revealed in future missions.”

Mars is an exceedingly hostile place. The planet’s surface is dry and frozen, and cosmic radiation and solar protons are constantly bombarding it. But that may not have always been the case—scientists believe water flowed on Mars between 2 and 2.5 billion years ago, which would’ve made the planet slightly more hospitable.

Researchers were curious to know what kind of life might have evolved—and, potentially, survived into the present—on the Red Planet. To attempt to answer that question, they mimicked the cold, arid conditions of Mars here on Earth with six species of microorganisms.

Quakes on Mars reveal there may be magma beneath the surface

Posted by in category: space

Mars may not be the geologically dead world we thought it was, as hints of magma have been discovered underground.

The Red Planet is thought to have been volcanically active in the past, but not for many millions of years. Now, by studying a cluster of more than 20 seismic events on Mars using data from NASA’s InSight lander mission, Simon Stähler at ETH Zurich in Switzerland and his colleagues have uncovered a likely magma deposit near Cerberus Fossae, a region of fissures created by fault lines.

InSight landed on Mars in 2018 with the objective of studying seismic waves that travel across the planet’s surface and from deep within its interior. By investigating the speed and frequency of these waves, we can better understand Mars’s geological structure.
