Reports this week suggest a near-collision between an Australian satellite and a suspected Chinese military satellite in space. Meanwhile, earlier this month, the U.S. government issued the first-ever space junk fine. The Federal Communications Commission handed a US$150,000 penalty to the DISH Network, a publicly traded company providing satellite TV services. It came as a ...
With technology increasingly embedded in our everyday lives, it is becoming more important to understand space weather and its impacts on tech. The Tonga volcano eruption penetrated the ionosphere and disrupted satellite navigation. When you hear “space weather,” you typically think of huge explosions on the Sun — coronal mass ejections hurled towards Earth, creating ...
In new studies published in Physical Review Letters and a special issue of Classical and Quantum Gravity, a team of researchers presents the most precise test yet of the Weak Equivalence Principle, a vital component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission, which tested the principle by measuring accelerations of ...
Two satellites headed to Mars — dubbed “Blue” and “Gold” — led by the University of California, Berkeley, on an interplanetary mission to orbit around Mars. This program has been officially authorized to prepare for launch in October 2024. The announcement last week by NASA means that by 2026, the spacecraft will likely be exploring ...
From the broadcasting of major events to tracking major developments on the planet and in the atmosphere, satellites launched by various countries benefit the human population in many ways. However, few are aware that these satellites are also causing light pollution. Results of a new study show that the satellites placed in orbit around the ...
When it comes to launching satellites designed to orbit the Earth, there are three potential destinations. These orbits, dubbed low, medium, and geosynchronous Earth orbits, or LEO (low Earth orbit), MEO (middle Earth orbit), and GEO (geosynchronous equatorial orbit), respectively, all exist within a specific height window above the planet’s surface. What is the difference ...
Time travel has always fascinated people. The idea that you can travel to the future to know what will happen or back to the past and influence the present is something that definitely piques interest. However, is time travel really possible according to physics? Theoretically, it does seem so. Traveling through time Just so you ...
I-Space has become the first company from China to successfully launch satellites into orbit. Previously, Chinese companies like LandSpace and OneSpace tried to launch satellites, but they failed. Into space The rocket, Hyperbola-1, measures 65.6 feet in length and was designed by I-Space. After launching from the Jiuquan Satellite Launch Center in Inner Mongolia, the ...
A new global, satellite-based study of Earth’s freshwater distribution found that wet areas are getting wetter and dry areas drier. The data suggest that this pattern is due to a variety of human and natural factors, including people’s use and management of water, human-caused climate change, and natural climate cycles. A NASA-led research team that ...
