The Parker Solar Probe will help scientists learn more about the solar wind, an exotic stew of magnetic forces, plasma and particles.
Following four decades of conflict, Afghanistan faces environmental challenges on many fronts, including a growing water crisis across the country. Less than a third of the country’s population has access to clean drinking water, causing thousands of deaths each year due to contamination and poor sanitation. Water resources are under severe stress due to recurrent drought, excessive water extraction for agriculture, and poor infrastructure.
Dark moonless nights for the summer Perseid Meteor Shower!
Over the past four years, NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) Project has been maturing a novel, three-dimensional, woven Thermal Protection System (TPS) technology for science missions recommended in the Planetary Science Decadal Survey. These missions—Venus probes and landers, Saturn and Uranus probes, and sample return missions to comets and asteroids—will require protection from intense atmospheric heating to reach their destinations. The off-the-shelf TPS product NASA employed on its previous mission to Venus is no longer available, but the technology resulting from the HEEET Project has resulted in an improved solution.
