NASA Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth. On Aug.11 and 12, 2013, the annual Perseid meteor shower will peak, filling the sky with streaks of light, commonly known as shooting stars. Such visually stunning showers are actually but the tip of the iceberg when it comes to meteoroids slamming into Earth's...

Mercury and its environment constitute a complex system that includes interactions among the interplanetary medium, the planet's magnetic field, its tenuous atmosphere (or exosphere), and its surface. Mercury's environment includes the solar wind and photon flux (flowing charged particles and light), solar and galactic cosmic rays, and the steady bombardment by micrometeoroids (solar system dust particles). The interactions of these elements of the space environment with the surface generate...

By Louis Bergeron, Stanford University Stanford researchers have completed the first successful tests in zero gravity of a canopy for CubeSats "“ the tiny satellites that hitch rides on rockets sending larger satellites into orbit. The goal is to gather data on what happens when micrometeoroids slam into a satellite. Such impacts often knock out electronic equipment on satellites. The encounters are poorly understood, but the canopies could be a first step in eventually building "black...

ESA -- At closing speeds reaching 50 thousand km per hour, even the smallest bits of space debris can cause serious harm to spacecraft; larger ones cause catastrophe. Near-Earth missions, like the International Space Station, now carry ever-more sophisticated shielding. Not only is space debris a hot topic, it is also a fascinating "” and growing "” field of space science. Professor Walter Flury, the European Space Agency's resident expert on space debris, casually uses rather...
