Kymeta to offer mission-critical LEO connectivity through OneWeb Technologies
Kymeta and OneWeb Technologies announced an agreement to distribute reliable, secure, and cost-effective broadband connectivity services to the U.S. government.
The new managed satellite service offering enables Kymeta to provide government customers with hardware solutions that are packaged with secure and resilient network access from OneWeb Technologies, a wholly owned subsidiary of low NASA and industry to collaborate on space communications initiative
NASA selected six American satellite communications (SATCOM) providers on April 20 to begin developing and demonstrating near-Earth space communication services that may support future agency missions.
For more than a year, the agency has been evaluating the feasibility of employing commercial SATCOM networks for near-Earth operations as it works to decommission its near-Earth satellite fl CGI supports creation of the European satellite constellation UN:IO
The European Commission has contracted IT service provider CGI as part of a consortium to contribute its expertise in the fields of space and cybersecurity for helping to build the independent European satellite constellation dubbed UN:IO. It is expected to begin operating commercial and institutional communication channels by 2025. ?
The European Union's top priority is a secure, extremel Curiosity goes oops Sols 3451-3452
Not that it matters, but exactly 100 sols ago, on January 7th, we were planning sols 3351 and 3352, and it was this blogger's turn to report on what was happening. Apparently, we were marvelling at the landscape - and dealing with a rock under the foot, well, the wheel.
Tosol, we were again dealing with a rock right under the rover, but this time, we were excited about it as the rover was Perseverance captures video of solar eclipse on Mars
NASA's Perseverance Mars rover has captured dramatic footage of Phobos, Mars' potato-shaped moon, crossing the face of the Sun. These observations can help scientists better understand the moon's orbit and how its gravity pulls on the Martian surface, ultimately shaping the Red Planet's crust and mantle.
Captured with Perseverance's next-generation Mastcam-Z camera on April 2, the 397th Ma Axiom crew set for return to Earth on Sunday, Crew-4 to launch days later
The first private astronaut crew aboard the International Space Station is set to return to Earth on Sunday after weather delays and NASA's Crew-4 mission will look to launch on Tuesday.
"The decision [to delay landing] was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to b Earth from Space: Earth Day
Each year on 22 April, people across the planet join forces to raise awareness about the depleting quality of the environment, the unequivocal effects of climate change and the importance of protecting our planet for future generations. We celebrate Earth Day every day at ESA. This week, this spectacular image of Earth is brought to you by the Meteosat Second Generation series of missions.
ESA’s Space Environment Report 2022
Since 2016, ESA’s Space Debris Office has published an annual Space Environment Report to provide a transparent overview of global space activities and determine how well these and other international debris-reduction measures are improving the long-term sustainability of spaceflight.
Here are some of the key findings of the 2022 report.
Key findings from the European State of the Climate Report
Europe experienced its warmest summer on record in 2021, accompanied by severe floods in western Europe and dry conditions in the Mediterranean. These are just some of the key findings from the Copernicus Climate Change Service’s European State of the Climate report released today. The in-depth report provides key insights and a comprehensive analysis of climate conditions in 2021, with a special focus on Europe and the Arctic.
Is Webb at its final temperature?
The Mid-Infrared Instrument (MIRI) on NASA's James Webb Space Telescope is now cooled by a gaseous helium cryocooler to under 7 Kelvin. With the cooler in its final state, the Webb team is operating the MIRI instrument this week as part of seventh and final stage of the telescope alignment. When the instrument is operating, the detectors and electronics produce heat, which is balanced by the cryocooler to keep MIRI at a stable, and very cold, operating temperature. The near-infrared instruments also warm up during operations and have to dissipate heat, although for these instruments this is done with passive cooling; the heat from the detectors and electronics is radiated into deep space.
Now that the instruments are at their operating temperatures, the telescope mirrors will also continue cooling down to their final temperatures, but they are not quite there yet. The primary mirror segments and the secondary mirror are made of beryllium (coated with gold). At cryogenic temperatures, beryllium has a long thermal time constant, which means that it takes a long time to cool or to heat up.
