WASHINGTON – L3Harris Technologies has redesigned its patented unfurlable mesh reflector antenna to meet growing demand from firms building satellites weighing roughly 180 to 1,000 kilograms. The latest version, called Smallsat Perimeter Truss, is one-third smaller and half the weight of the Advanced Perimeter Truss, which L3Harris produces for large government and commercial geostationary satellites.

This image of a dust storm on Mars was taken in 2007 by Mars Reconnaissance Orbiter, of NASA. Water ice clouds are visible near the polar region, with grooves produced by pressure or temperature oscillations that are features of gravity waves. These waves were most likely caused by wind blowing over a crater ridge. Credits:

Jupiter’s Great Red Spot. Credit: NASA A team of researchers affiliated with Aix-Marseille Université has found evidence that suggests the thickness of Jupiter’s red spot has remained relatively stable as its surface area has decreased. In their paper published in the journal Nature Physics, the group describes how they estimated the thickness of the spot
