Dispersive Holdings Inc. (Dispersive), a rapidly emerging leader in the stealth networking and Zero Trust Network Access (ZTNA) arena, and Ovzon, a world-leading provider of SATCOM-as-a-Service and mobile satellite communications solutions, have reached an agreement in which Ovzon will utilize Dispersive to provide enhanced, secure satellite communications as part of their total solution. The enduring stellar lifecycle in 30 Doradus
Wednesday, 11 January 2023 06:12
The largest and brightest region of star formation in the Local Group of galaxies, including the Milky Way, is called 30 Doradus (or, informally, the Tarantula Nebula). Located in the Large Magellanic Cloud, a small neighbor galaxy to the Milky Way, 30 Doradus has long been studied by astronomers who want to better understand how stars like the Sun are born and evolve.
NASA's Chandra X-ray NASA missions find 'jetlets' could power the solar wind
Wednesday, 11 January 2023 06:12
Scientists with NASA's Parker Solar Probe mission have uncovered significant new clues about the origins of the solar wind - a continual stream of charged particles released from the Sun that fills the solar system.
Observations from multiple space and ground-based observatories show the solar wind could be largely fueled by small-scale jets, or "jetlets," at the base of the corona - the S NASA scientists study life origins by simulating a cosmic evolution

Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals. Because of amino acids' relationship to living things scientists are eager to understand the origins of these molecules. After all, amino acids may have helped spawn life on Earth after being delivered here about 4 billion years ago by pieces of asteroids or comets. SwRI scientists find evidence for magnetic reconnection between Ganymede and Jupiter
Wednesday, 11 January 2023 06:12
In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team led by Southwest Research Institute used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and reoriented, heating and accelerating the charged particles in the region. NASA wants you to help study planets around other stars
Wednesday, 11 January 2023 06:12
More than 5,000 planets have been confirmed to exist outside our solar system, featuring a wide array of characteristics like clouds made of glass and twin suns. Scientists estimate there could be millions more exoplanets in our home galaxy alone, which means professional astronomers could use your help tracking and studying them.

Scientific samples, hardware return from International Space Station for more study
Tuesday, 10 January 2023 21:16
A radiation protection vest, olive oil, and sutured tissues are among the scientific samples returning from the International Space Station on the 26th SpaceX commercial resupply services mission for NASA. The Dragon spacecraft, which arrived at the station Nov. 27, is scheduled to undock on January 9, with splashdown January 11 off the coast of Florida.
The cargo returns to NASA's Kennedy Space Center in Florida, where scientists can make additional observations and analyses of their experiments before the effects of gravity fully kick back in. Many also conduct more in-depth analysis later in their home labs.

China unable to reestablish contact with its Zhurong Mars rover
Tuesday, 10 January 2023 17:43
China's National Space Administration (CNSA) has been hoping to reestablish communications with the Zhurong Mars rover, but so far, their efforts have been unsuccessful. Zhurong was put into hibernation over six months ago as it hunkered down in attempts to survive the Martian winter.
But it's been a tough winter in Utopia Planetia in Mars northern hemisphere where Zhurong is located. Not only were the temperatures extremely low, colder than -100°C (-148°F), but a regional dust storm severely reduced the likelihood of the rover collecting any power with its solar panels. This is the same dust storm that has hastened the end of NASA's Mars InSight mission.
According to the South China Morning Post, the mission team predicted Zhurong would resume operations around December 26 as the planet's northern hemisphere entered its spring season and environmental conditions improved.
