These ruggedized parabolic broadband terminals are designed for use in land, maritime, and airborne applications. The new terminals were developed with a focus on performance, mobility, and resiliency. They offer a variety of integration options, enhancing Ovzon's SATCOM-as-a-Service offering
NASA's Perseverance Reaches Key Scientific Target in Ancient Riverbed
Tuesday, 18 June 2024 03:45Initially considered a simple route free of obstructions, Neretva Vallis has presented numerous geological opportunities for the science team. After navigating through a dune field to avoid challenging boulders, NASA's Perseverance Mars rover arrived at its latest area of interest on June 9. The route change not only reduced travel time to the "Bright Angel" site by several weeks but also
Voyager 1 Resumes Full Science Operations
Tuesday, 18 June 2024 03:45The spacecraft has resumed gathering information about interstellar space. NASA's Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023. The team partially resolved the issue in April when they prompted the spacecraft to begin returning engineering data, which includes information about the health and s
Mitsubishi Electric to Ship GaN MMIC Power Amplifier Samples for Ka-band SATCOM
Tuesday, 18 June 2024 03:45Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it will begin shipping samples of 8W and 14W gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) power amplifiers for use in Ka-band satellite-communication (SATCOM) earth stations from July 1. While the mainstream frequency for satellite communications is currently the Ku-band (13GHz to 14GHz), the higher
Pair Plasmas Generated in Laboratory Setting
Tuesday, 18 June 2024 03:45Black holes and neutron stars are among the densest known objects in the universe. Within and around these environments exist plasmas, the fourth state of matter alongside solids, liquids, and gases. Specifically, these plasmas are known as relativistic electron-positron pair plasmas because they consist of electrons and positrons moving at nearly the speed of light. While these plasmas ar
Watery Planets Orbiting Dead Stars Could Be Good Candidates for Life Study
Tuesday, 18 June 2024 03:45The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The challenge lies in detecting the shadow of a planet against a former star that has shrunk significantly and ensuring that it has maintained its water oceans for billions of years, even after enduring
7 Essential Tools for Diagnosing and Resolving Dirty Power Issues
Monday, 17 June 2024 22:41Many people and businesses encounter challenges related to power. These include disturbances such as sudden voltage changes, surges, dips, fluctuations, and unwanted harmonics that can disrupt equipment operations and harm delicate electronic gadgets. Identifying and addressing power problems is essential to preventing data loss, frequent equipment breakdowns, and potential safety risks. I

Monday, 17 June 2024 17:56Warp drives could generate gravitational waves
Monday, 17 June 2024 17:18Will future humans use warp drives to explore the cosmos? We're in no position to eliminate the possibility. But if our distant descendants ever do, it won't involve dilithium crystals, and Scottish accents will have evaporated into history by then.
Warp drives have their roots in one of the most popular science fiction franchises ever, but they do have a scientific basis. A new paper examines the science behind them and asks if a warp drive containment failure would emit detectable gravitational waves.
The paper is titled "What no one has seen before: gravitational waveforms from warp drive collapse," and it is posted to the arXiv preprint server. The authors are Katy Clough, Tim Dietrich, and Sebastian Khan, physicists from institutions in the U.K.
Cells grown in microgravity show 3D structures that could be used in medicine
Monday, 17 June 2024 17:01Humanity is on the verge of entering a new era of space exploration, with the Artemis III mission planning to return humans to the moon in 2026, for the first time in 50 years. Not only will Artemis see a woman and a person of color walk on the lunar surface for the first time, but the week-long mission to the south pole of the moon will begin a period of longer and longer stays in space.
This means that the impact of space environments on human health needs to be thoroughly investigated. This includes understanding the effect of "weightlessness" due to the microgravity found in space on physiology. While this seems to be negative, scientists are also investigating the impact of microgravity on cells, which suggests that microgravity can be advantageous.
