A Southwest Research Institute scientist measured the properties of ice-brine mixtures as cold as -145 degrees Fahrenheit to help confirm that salty water likely exists between grains of ice or sediment under the ice cap at Mars' south pole. Laboratory measurements conducted by SwRI geophysicist Dr. David Stillman support oddly bright reflections detected by the MARSIS subsurface sounding radar A planetary dynamical crime scene at 14 Herculis

The forensic evidence left in the 14 Her giant planetary system suggests an active dynamical past. Two giant planets, several times more massive than Jupiter, in highly eccentric orbits around a solar-type star were found orbiting at nearly right angles to each other.

NASA's latest and snazziest satellite, the James Webb Space Telescope (JWST), launched on Christmas Day, deployed its 21-foot-wide mirror a mere two weeks ago and reached its orbital destination earlier this week. With a flashy new telescope now nearly a reality, astronomers at the University of California, Berkeley, are chomping at the bit to start observing.

Since its launch on Christmas day, astronomers have eagerly followed the complex deployment and unfurling of NASA's James Webb Space Telescope - the largest to ever take to the skies.
Right around the time this article is published, it's expected Webb will have reached a place called the Earth-Sun "second Lagrange point", or "L2". This is a point in space about 1.5 million kilometres away UW alum helped pack James Webb telescope for space travel

A University of Wisconsin-Madison engineering mechanics alumnus made important contributions to NASA's James Webb Space Telescope, which arrived at its home in distant orbit Monday.
The telescope, the world's largest and most powerful space science observatory, launched on Dec. 25, starting its journey toward its destination about 1 million miles from Earth.

Wednesday, 26 January 2022 07:29 Write a comment
Antennas are among the most complex systems aboard a satellite – making them demanding to produce and often unpredictable to test. Tiny variables in their building, mounting or operation may impact their working performance in a big way. So ESA teamed up with Danish company TICRA to develop a method of forecasting such discrepancies well before an antenna construction even starts.
