Sep 30, 2015 · These particles come from galactic cosmic rays, often known as GCRs. They’re particles accelerated to near the speed of light that shoot into our solar system from other stars in the Milky Way or even other galaxies.

Feb 4, 2025 · Roussel studies how cosmic radiation from supernovae affects biomarkers that could point to the existence of past life on Mars, which is inhospitable to current life due to its freezing temperatures, high levels of radiation and dry climate.

Oct 7, 2024 · Cosmic ray heavy ions may fragment in the atmosphere, producing lower-mass ions that can still harm astronauts on the surface. Mars' thin atmosphere allows more Ultraviolet light to reach the surface, compared to Earth.

Oct 7, 2024 · Cosmic radiation (also known as cosmic rays) is created in deep space by strong electric and magnetic processes, stripping atoms down to the core and accelerating them to high velocities. Those high energetic particles reach the surface of Mars due to …

Curiosity rover began making detailed measurements of the cosmic ray and energetic particle radiation environment on the surface of Mars on 7 August 2012. We report and discuss measurements of the absorbed dose and dose equivalent

May 31, 2013 · Here we report measurements of the energetic particle radiation environment inside the Mars Science Laboratory (MSL) during its cruise to Mars between 6 December 2011 and 14 July 2012, with implications for future human Mars missions.

Dec 12, 2024 · A study published in Astrobiology on November 13 has revealed the challenges posed by cosmic radiation in preserving potential traces of life on Mars. Researchers simulated the effects of cosmic rays on lipids, crucial molecular structures found in cell membranes.

2 days ago · For Artemis and Mars missions, the primary focus will be on the radiation received beyond low Earth orbit (LEO) in the form of solar particle events (solar storms) and galactic cosmic rays (GCR).

Aug 16, 2024 · Space radiation comes from two main sources: solar activity in the form of solar flares, and energetic particles called galactic cosmic rays.

Jun 29, 2011 · To facilitate making estimates of human radiation exposures for crew operations in the Martian atmosphere, lookup tables have been generated that provide doses for critical body organs and effective doses for exposures from galactic cosmic rays …

Sep 30, 2015 · These particles come from galactic cosmic rays, often known as GCRs. They’re particles accelerated to near the speed of light that shoot into our solar system from other stars in the Milky Way or even other galaxies.

1 day ago · Figure 1: Radial profiles of the X-ray surface brightness of three samples of galaxies. The shaded regions show observational data from eROSITA, while the dashed lines show predictions from cosmic ray models. Blue corresponds to galaxies around the mass of the Milky Way, green around the mass of Andromeda, and red twice the mass of Andromeda.

May 4, 2015 · Mice zapped with cosmic rays can incur brain damage, suggesting that astronauts' mental performance could suffer over time on deep-space missions to Mars and beyond, researchers say.

20 hours ago · This means the high-energy particles are generated as the result of cosmic rays interacting with the cosmic microwave background – the radiation left over from the Big Bang – or background ...

6 hours ago · What do clouds on Mars look like? Well, a new video stitched together from images captured by NASA's Curiosity rover offers a glimpse. In this video, delicate red-and-green-tinted clouds are seen ...

Feb 6, 2025 · Tracing Seismic Waves Through Mars. By analyzing how seismic waves travel through Mars’ crust, mantle, and core, scientists can better understand the planet’s interior structure. This research not only sheds light on Mars but also helps explain how rocky planets like Earth and the Moon evolved.

1 day ago · NASA's Curiosity Mars rover captured this feather-shaped iridescent cloud just after sunset on Jan. 27, 2023. Studying the colors in iridescent clouds tells ... Euclid Discovers Einstein Ring in Our Cosmic Backyard. article 3 days ago. 2 min read. Hubble Goes Supernova Hunting. article 6 days ago. Highlights.

3 days ago · Supernova remnants, the exploded guts of a blown-up star, can be unsurprisingly hot and energetic, producing amazing images in infrared (heat) and X-rays. One particularly picturesque supernova remnant, known as G299, shines and …
