Astronauts going to Mars will receive many lifetimes worth of radiation
Write a comment
In a recent study to be published in Space Physics, an international team of researchers discuss an in-depth study examining the long-term physiological effects of solar radiation on astronauts with emphasis on future astronauts traveling to Mars to include steps we can take to help mitigate the risk of such solar radiation exposure. The researchers hailed from the United Arab Emirates, New Zealand, India, United States, Italy, Greece, and Germany, and their study helps us better understand the in-depth, long-term health impacts of astronauts during long-term space missions, specifically to Mars and beyond.
"Exposure to ionizing radiation is one of the main health risks to astronauts in crewed missions to Mars," said Dr. Dimitra Atri, a Research Scientist at New York University Abu Dhabi, and lead author of the study. "Going to Mars is going to be humanity's ultimate adventure in the 21st century—it would be unfortunate if the mission is successful, but astronauts suffer major health issues or even die because of radiation exposure.
NASA engineer develops tiny, high-powered laser to find water on the moon
Write a comment
Finding water on the moon could be easier with a Goddard technology that uses an effect called quantum tunneling to generate a high-powered terahertz laser, filling a gap in existing laser technology.
Locating water and other resources is a NASA priority crucial to exploring Earth's natural satellite and other objects in the solar system and beyond. Previous experiments inferred, then confirmed the existence of small amounts of water across the moon. However, most technologies do not distinguish among water, free hydrogen ions, and hydroxyl, as the broadband detectors used cannot distinguish between the different volatiles.

The countdown has started for the first human-rated launch to the Moon in over half a century. ESA’s European Service Module will be powering the Orion spacecraft to our natural satellite and back.
Webb detects carbon dioxide in exoplanet atmosphere
Write a comment
The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away. The result provides important insights into the composition and formation of the planet, and is indicative of Webb’s ability to also detect and measure carbon dioxide in the thinner atmospheres of smaller rocky planets.
Keele researchers study turbulence raging inside distant stars

Stunning new images created by Keele researchers highlight the turbulent flow of energy inside distant stars.
They were created using the 3D simulation software "PROMPI", which scientists have been using to investigate stellar interiors with the aim of understanding the science of stellar evolution and black holes.
For years scientists have used one-dimensional models to explain and Scientists say exoplanet 100 light years from Earth may be covered with deep ocean
Write a comment
A team of researchers have discovered an exoplanet about 100 light years away from Earth in the Draco constellation, and they say the world appears to be covered in a deep ocean.
The exoplanet - called TOI-1452b - is slightly larger than the Earth and is located in a "Goldilocks zone," where temperatures are neither too hot nor too cold for liquid water to exist. Therefore, astronomer Slow and steady does it on Sol 3564

We are making slow but steady progress through the "Paraitepuy pass," having passed the approximate halfway point over the weekend. Today's one sol plan found us staring around the corner at the neck of the pass and considering our drive path forward.
Sometimes, our drive forward is smooth and flat ... neither word can be used here! Our drive forward has abundant sand and sharp rocks, so f Sol 3565: Over, Around, and Through

We filled much of today's plan imaging the wonders around and ahead of us as we pick our way through "Paraitepuy Pass" - the towering buttes, geologic relationships, and layers that have drawn our attention for a literal decade.
But it is also fun to look back on how we got to where we are. The image above traces a small segment of our path traversing the obstacles that guard the pass - ov Curiosity Versus the Sand Again: Sols 3566-3567

The "road" through Paraitepuy pass continues to challenge our intrepid Curiosity rover. We attempted to cross another large sand ripple (formally called a transverse aeolian ridge, or TAR) in Tuesday's plan.
However, we found out this morning that Curiosity had automatically stopped the drive when the rover's wheels slipped more than expected right before they reached the crest of the TAR. Uranus to begin reversing path across the night sky on Wednesday

As part of a cosmic phenomenon called retrograde motion, Uranus - the second-to-last planet in our solar system - will reverse its eastward course on Wednesday and begin moving west in the sky for a few months.
Retrograde motion occurs as the Earth moves around the sun and the stellar views at night change little by little. The orbit, in turn, makes objects like planets in our solar s
