Studying The Effects Of Microgravity And Radiation On Human Cells
2014-02-28 08:41:19

Lawrence LeBlond for redOrbit.com - Your Universe Online Life aboard the International Space Station (ISS) may seem like a carefree existence, but a wealth of evidence has proven otherwise. Years of research shows that the effects of microgravity wreaks havoc on the human body. However, microgravity isn’t the only thing that astronauts need to worry about in space. Going into space means exposure to radiation, which is known to damage our DNA. And when DNA tries to repair itself,...

BOULDER, Colo., Feb. 20, 2014 /PRNewswire/ -- Significant attention has been given to methods of shielding human space participants from radiation on missions. But what if some astronauts suffer from susceptible DNA before entering the space radiation environment? Two American scientists have proposed that certain astronaut molecular profiles may 1) reduce inherent DNA stability, 2) slow DNA repair, and 3) render DNA more susceptible to mutational events when exposed to the...

Rocket Launches Affected By Space Radiation

NASA On Jan. 8, 2014, Orbital Sciences Corp. elected to scrub that day's launch attempt of an Antares rocket from NASA’s Wallops Flight Facility, Wallops Island, Va., due to unusually high levels of space radiation – an example of the ways in which space weather can affect human technology. Monitoring for space radiation – which refers to excessive high-energy protons in near-Earth space, often funneled in from space in association with an event on the sun such as the solar flares...

Radiation Hazards Of Deep Space Travel Quantified By Researchers
2013-11-19 09:06:48

April Flowers for redOrbit.com - Your Universe Online Comprehensive findings on space-based radiation as measured by a detector aboard NASA’s Lunar Reconnaissance Orbiter (LRO) have been published by a team of scientists led by the University of New Hampshire. The findings, published in a special edition of Space Weather, provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars. The findings...

Prairie View A&M And NASA Goddard Collaborate On Radiation Effects Research
2013-11-04 13:54:06

NASA When Alvin Boutte presented his graduate work at the 2010 National Society of Black Engineers (NSBE) Aerospace Systems Conference in Los Angeles, Calif., he had no idea that he was about to connect with someone that would be instrumental in guiding his career. In attendance was Anthony Sanders from the Applied Engineering and Technology Directorate (AETD) at NASA’s Goddard Space Flight Center, Greenbelt, Md. The radiation engineering work that Boutte did at Prairie View A&M...

HOUSTON, Aug. 14, 2013 /PRNewswire-USNewswire/ -- The National Space Biomedical Research Institute (NSBRI) is soliciting for program proposals to establish a Center for Space Radiation Research (CSRR). The CSRR will build upon important discoveries made by the NSBRI Center of Acute Radiation Research and extend them by characterizing and quantifying the effects of space radiation on living systems. Operating in close partnership with NASA's Human Research Program, the CSRR will be...

DNA Sequencing Microchip Tested For Trip To Mars
2013-07-09 11:11:13

Brett Smith for redOrbit.com - Your Universe Online As space agencies make plans to send scientific equipment to Mars, they must take into consideration the demands of a grueling trek across the solar system. The journey exposes spacecraft and their precious cargo to frigid temperatures and harsh solar radiation, meaning the often sensitive equipment onboard must be designed to handle these physical challenges. Aiming to build a system that excavates the Red Planet's surface for genetic...

Cosmic Radiation May Accelerate Onset Of Alzheimer's
2013-01-01 05:21:42

April Flowers for redOrbit.com - Your Universe Online Space travel is fraught with dangers for astronauts and equipment alike. A new study, led by the University of Rochester Medical Center, reveals that it may be much more dangerous than previously thought. The findings, published in the journal PLOS ONE, show that cosmic radiation — which would bombard astronauts on deep space missions — could accelerate the onset of Alzheimer's disease. "Galactic cosmic radiation poses a...
