NASA eyes November for launch of NOAA's JPSS-2
Wednesday, 01 June 2022 11:31
NASA and the National Oceanic and Atmospheric Administration (NOAA) are now targeting Nov. 1, 2022, as the new launch date for NOAA's Joint Polar Satellite System-2 (JPSS-2) satellite mission. During recent tests of a key instrument designed to collect visible and infrared images, the team found and corrected an issue, which resulted in additional time needed to complete thermal vacuum testing.
The Visible Infrared Imaging Radiometer Suite instrument, or VIIRS, experienced a test equipment issue during thermal vacuum testing. Engineers determined the issue was the result of the movement of test equipment caused by temperature fluctuations during the test. After modifying the test set up, the team retested the system, and it demonstrated excellent performance.
JPSS-2, the third satellite in the Joint Polar Satellite System series, is scheduled to lift off from the Vandenberg Space Force Base in California, on a United Launch Alliance (ULA) Atlas V rocket.

Mitsubishi Electric has developed the prototype of what is believed to be the world's first* optical receiver for use in laser communication terminals (LCTs), that integrates space optical communication using laser beams and a function to detect the direction of received beams in the 1.5-um band, a general-purposeband used for terrestrial optical fiber communications and other applications.

Watching the skies for large asteroids that could pose a hazard to the Earth is a global endeavor. So, to test their operational readiness, the international planetary defense community will sometimes use a real asteroid's close approach as a mock encounter with a "new" potentially hazardous asteroid.

In the early 2000s, a new set of data brought down the chemical abundances at the surface of the Sun, contradicting the values predicted by the standard models used by astrophysicists. Often challenged, these new abundances made it through several new analyses. As they seemed to prove correct, it was thus up to the solar models to adapt, especially since they serve as

The delightful view of all five naked-eye planets will greet early risers throughout the month of June. While seeing two or three planets close together (in what's known as a conjunction) is a rather common occurrence, seeing five is somewhat more rare. And what's even more remarkable about this month's lineup is that the planets are arranged in their natural order from the Sun.
