New Research Supports Modified Gravity Theory Over Dark Matter
Write a comment
Scientists at Case Western Reserve University have found new evidence that could change our understanding of the cosmos. Tobias Mistele, a post-doctoral scholar at the Department of Astronomy, used gravitational lensing to investigate dark matter. He discovered that the rotation curves of galaxies remain flat for millions of light years.
Previously, it was believed that these curves must d Kyocera Installs Fine Cordierite Ceramic Mirror on ISS for Optical Communications

Kyocera Corporation (President: Hideo Tanimoto, hereinafter: Kyocera) announced that its "Fine Cordierite" ceramic mirror has been chosen for use in experimental equipment to conduct optical communication between the International Space Station (ISS) and a mobile optical station on Earth. This is the first time*1 that cordierite has been adopted for such a purpose.

Chinese rocket scientists and engineers conducted a critical test of a propulsion system for a new carrier rocket, essential for China's future manned moon landings.
"During the ignition test that took place at an engine testing facility in Beijing's Fengtai district, three YF-100K engines spewed fire for several minutes, generating a combined thrust of 382 metric tons, according to the Ch Rocket Lab Signs Largest Electron Launch Deal with Synspective

The Luxembourg Institute of Science and Technology (LIST) has launched its CubeSat project, LIST-SAT-01, marking the first Luxembourgish nanosatellite initiative with an in-house scientific experiment. This project aims to test and advance technologies developed at LIST, increasing their Technology Readiness Level (TRL) and achieving flight heritage for on-board technologies.
At the core o 7 Essential Tools for Diagnosing and Resolving Dirty Power Issues
Write a comment
Many 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 Cells grown in microgravity show 3D structures that could be used in medicine

Humanity 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.
Warp drives could generate gravitational waves
Write a comment
Will 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.

NASA again delays Boeing Starliner's return home
Write a comment
NASA said June 14 that the Boeing Starliner and its crew will now return to Earth from the International Space Station no earlier than Saturday, June 22.
"The extra time allows the team to finalize departure planning and operations while the spacecraft remains cleared for crew emergency return scenarios within the flight rules," NASA said on its Kennedy Space Center blog.
The Starliner's test mission launched on June 5 from KSC with astronauts Butch Whitmore and Suni Williams. During its journey to the ISS, helium leaks were found in the spacecraft's thruster system.
Earlier in the week, NASA said its teams were continuing to assess what impacts, if any, the five small helium leaks would have on Whitmore's and Williams' return to Earth. At that time, the space agency scheduled Starliner's return for Tuesday, June 18, "pending weather and spacecraft readiness."
NASA has said that engineers had determined the helium leaks shouldn't impact Starliner's return. The agency said the craft had enough helium for 70 hours of free flight time when only seven hours would be required as part of its journey home.
