    NASA's Human Research Program (HRP) is dedicated to discovering the best methods and technologies to support safe, productive human space travel. HRP enables space exploration by reducing the risks to astronaut health and performance using ground research facilities, the International Space Station, and analog environments. This leads to the development and delivery of a program focused on: human health, performance, and habitability standards; countermeasures and risk mitigation solutions; and advanced habitability and medical support technologies. HRP supports innovative, scientific human research by funding more than 300 research grants to respected universities, hospitals and NASA centers to over 200 researchers in more than 30 states.

    Galactic Secrets Revealed

    Countless galaxies vie for attention in this dazzling image of the Fornax Cluster, some appearing only as pinpricks of light while others dominate the foreground. One of these is the lenticular galaxy NGC 1316. The turbulent past of this much-studied galaxy has left it with a delicate structure of loops, arcs and rings that astronomers have now imaged in greater detail than ever before with the VLT Survey Telescope. This image was processed with the VST-Tube data reduction program. Credit: ESO/A. Grado and L. Limatola

    Astronomers recently discovered that spots on the surface of a supergiant star are driving huge spiral structures in its stellar wind. Massive stars are responsible for producing the heavy elements that make up all life on Earth. At the end of their lives they scatter the material into interstellar space in catastrophic explosions ie supernovae – without these dramatic events, our solar system would never have formed.

    Zeta Puppis is an evolved massive star known as a ‘supergiant’...

    To keep Saturn’s A Ring contained, its Moons Stand United

    For 3 decades, astronomers thought that only Saturn’s moon Janus confined the planet’s A ring – the largest and farthest of the visible rings. But after poring over NASA’s Cassini mission data, Cornell astronomers now conclude that the teamwork of seven moons keeps this ring corralled. Without forces to hold the A ring in check, the ring would keep spreading out and ultimately disappear...
