Something spooky is happening at the edge of the solar system

Posted by in categories: particle physics, space

Just in time for Halloween, scientists have discovered something spooky and strange occurring at the edge of the solar system: The heliopause — the boundary between the heliosphere (the bubble of solar wind encompassing the solar system) and the interstellar medium (the material between the stars) appears to be rippling and creating oblique angles in an unexpected manner.

The general concept that the heliopause changes shape is not new; over the past decade, researchers have determined that it is not static. They made this discovery using data from Voyager 1 and Voyager 2, the only two spacecraft to exit the heliosphere thus far, as well as NASA’s Interstellar Boundary Explorer (IBEX) satellite, which studies the emissions of energetic neutral atoms (ENAs) that are created when solar winds and the interstellar medium interact.

NASA Psyche Asteroid Mission Will Go Forward

Posted by in categories: government, space

The mission team continues to complete testing of the spacecraft’s flight software in preparation for the 2023 launch date.

On Friday, October 29, NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”

Perseverance rover to drop off samples for return to Earth

Posted by in categories: futurism, space

The NASA Perseverance rover isn’t only exploring Mars for the scientific discoveries it can make now — it’s also paving the way for future missions which intend to bring samples back from Mars to Earth for the first time. This complicated plan involves multiple vehicles including spacecraft, a lander, and two helicopters, which will work together to collect the samples from the Martian surface, take them to orbit, and return them to Earth. But Perseverance is getting the process started by collecting samples, sealing them up in tubes, and leaving these tubes on the surface for future missions to collect.

Now, NASA and the European Space Agency (ESA) have announced that they have selected the first samples to be deposited on the surface ready for collection. “Never before has a scientifically curated collection of samples from another planet been collected and placed for return to Earth,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters, in a statement. “NASA and ESA have reviewed the proposed site and the Mars samples that will be deployed for this cache as soon as next month. When that first tube is positioned on the surface, it will be a historic moment in space exploration.”

Ten of the 14 samples which Perseverance has collected so far will be deposited in a region of the Jezero Crater called Three Forks. This region was chosen as it is flat and does not have obstacles like large boulders which could cause issues for future collection. The samples chosen for collection include both igneous and sedimentary rocks collected from the rover’s 8-mile journey across Jezero.

Astronomers find a doomed Earth-sized world around a violent star

Posted by in category: space

A group of astronomers studying the planet GJ 1252b found an answer, and it’s not pretty.

What if you placed an Earth-sized planet in a close orbit around an M dwarf star? It’s more than an academic question since M dwarfs are the most numerous stars we know.

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.
