Solar Sailing: applications and technology advancement [PDF]

, 2011
Harnessing the power of the Sun to propel a spacecraft may appear somewhat ambitious and the observation that light exerts a force contradicts everyday experiences.

The longitudinal behavioral effects of acute exposure to galactic cosmic radiation in female C57BL/6J mice: Implications for deep space missions, female crews, and potential antioxidant countermeasures

Journal of Neurochemistry, Volume 169, Issue 1, January 2025.
Mars‐bound astronauts will be exposed to unavoidable galactic cosmic radiation (GCR), but the long‐term impact of GCR on females is uncertain. Using touchscreen‐ and arena‐based behavioral tests, we find GCR decreased stimulus–response learning in female mice vs.

The Radiation Impact of Solar Energetic Particle Events on the Moon: A Statistical Study Using Data‐Based Modeling Results

Space Weather, Volume 22, Issue 11, November 2024.
Abstract The Moon lacks a global magnetic field and atmosphere, leaving its surface been directly exposed to high‐energy cosmic radiation. Sporadic Solar Particle Events are sources of a significant radiation exposure, potentially posing serious threats to the health of astronauts exploring the Moon.

AOP Report: Development of an adverse outcome pathway for deposition of energy leading to bone loss

Environmental and Molecular Mutagenesis, Volume 65, Issue S3, Page 85-111, October 2024.
Abstract Bone loss, commonly seen in osteoporosis, is a condition that entails a progressive decline of bone mineral density and microarchitecture, often seen in post‐menopausal women. Bone loss has also been widely reported in astronauts exposed to a plethora of stressors and in patients with osteoporosis following radiotherapy for cancer.

Dust Grain Orbital Behavior Around Ceres

, 2003
Many asteroids show indications they have undergone impacts with meteoroid particles having radii between 0.01 m and 1 m. During such impacts, small dust grains will be ejected at the impact site.

New measurements of total ionizing dose in the lunar environment [PDF]

, 2011
[1] We report new measurements of solar minimum ionizing radiation dose at the Moon onboard the Lunar Reconnaissance Orbiter (LRO) from June 2009 through May 2010.

AOP report: Development of an adverse outcome pathway for deposition of energy leading to abnormal vascular remodeling

Environmental and Molecular Mutagenesis, Volume 65, Issue S3, Page 4-30, October 2024.
Abstract Cardiovascular diseases (CVDs) are complex, encompassing many types of heart pathophysiologies and associated etiologies. Radiotherapy studies have shown that fractionated radiation exposure at high doses (3–17 Gy) to the heart increases the incidence of CVD.

Remote automated multi-generational growth and observation of an animal in low Earth orbit [PDF]

, 2012
The ultimate survival of humanity is dependent upon colonization of other planetary bodies. Key challenges to such habitation are (patho)physiologic changes induced by known, and unknown, factors associated with long-duration and distance space ...
