SPACE STATION MOLD SURVIVES HIGH DOSES OF IONIZING RADIATION

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station’s walls to prevent mold from becoming a health problem. New research being presented here finds mold spores may also survive on the outside walls of spacecraft. […]

NASA’S MARS 2020 WILL BLAZE A TRAIL — FOR HUMANS

When a female astronaut first sets foot on the Moon in 2024, the historic moment will represent a step toward another NASA first: eventually putting humans on Mars. NASA’s latest robotic mission to the Red Planet, Mars 2020, aims to help future astronauts brave that inhospitable landscape. While the science goal of the Mars 2020 […]

PROLONGED SPACEFLIGHT COULD WEAKEN ASTRONAUTS’ IMMUNE SYSTEMS

NASA hopes to send humans to Mars by the 2030s on a round-trip mission that could take up to three years – far longer than any human has ever traveled in space. Such long-term spaceflights could adversely affect certain cells in the immune systems of astronauts, according to a new study led by University of […]

RELATIVISTIC ELECTRONS UNCOVERED WITH NASA’S VAN ALLEN PROBES

Earth’s radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA’s Van Allen Probes mission show that the fastest, most energetic electrons in the inner radiation belt are not present as much of the […]

NASA, SMITHSONIAN’S NATIONAL AIR AND SPACE MUSEUM HOST DISCUSSION ON SOLAR HAZARDS IN EXPLORATION

Understanding the hazards of space weather on crewed and robotic missions is vital to informing plans for NASA’s Journey to Mars and other missions into our solar system, and beyond. Veteran NASA astronaut John Grunsfeld and solar experts will discuss that and more during a panel discussion at 1 p.m. EDT, Tuesday, October 25. The […]

MARS BOUND ASTRONAUTS FACE CHRONIC DEMENTIA RISK

Will astronauts traveling to Mars remember much of it? That’s the question concerning University of California, Irvine scientists probing a phenomenon called “space brain.” UCI’s Charles Limoli and colleagues found that exposure to highly energetic charged particles – much like those found in the galactic cosmic rays that will bombard astronauts during extended spaceflights – […]

SCIENTISTS AND ENGINEERS EVALUATE ORION RADIATION PROTECTION PLAN

When astronauts in Orion venture far beyond Earth into deep space, they will expand humanity’s frontier and push the boundaries of exploration. While the spacecraft is designed with systems and materials to keep the crew safe during their journey, leaving the protection of Earth’s magnetosphere exposes astronauts to a radiation environment in space that scientists […]

50TH ANNIVERSARY OF LUNAR ORBITER 1 MISSION

Today is the 50th anniversary of the launch of the first of five lunar orbiters that returned images of 99 percent of both the near- and far-side surfaces of the moon. The orbiters sent back a total of 3,062 photos. Lunar Orbiter 1, built by The Boeing Co., was launched August 10, 1966 on an […]

APOLLO ASTRONAUTS EXPERIENCING HIGHER RATES OF CARDIOVASCULAR-RELATED DEATHS

Members of the successful Apollo space program are experiencing higher rates of cardiovascular problems that are thought to be caused by their exposure to deep space radiation, according to a Florida State University researcher. In a new paper in Scientific Reports, FSU Dean of the College of Human Sciences and Professor Michael Delp explains that […]

NASA CHALLENGE AIMS TO GROW HUMAN TISSUE TO AID IN DEEP SPACE EXPLORATION

NASA, in partnership with the nonprofit Methuselah Foundation’s New Organ Alliance, is seeking ways to advance the field of bioengineering through a new prize competition. The Vascular Tissue Challenge offers a $500,000 prize to be divided among the first three teams that successfully create thick, metabolically-functional human vascularized organ tissue in a controlled laboratory environment.
