Russian Scientists Test a Plasma Engine that could Shrink Mars Travel to 30 Days

Astronomy, Astrophysics /

Scientists tied to Rosatom have revealed a plasma engine that could cut Earth–Mars travel to 30–60 days. The announcement has renewed discussion about the future of space exploration and whether such technology could realistically support interplanetary missions. Developed by engineers at the Rosatom Research Institute, the project focuses on nuclear and advanced propulsion systems. Unlike […]

BepiColombo Mio and GEOTAIL Observe Similar Magnetosphere Wave Frequencies

Astronomy, Planetary Science /

An international team from Kanazawa University (Japan), Tohoku University (Japan), LPP (France), and collaborators has shown that chorus emissions—natural electromagnetic waves well-known in Earth’s magnetosphere—also appear in Mercury’s magnetosphere, displaying similar chirping frequency patterns. BepiColombo’s Mio recorded audible plasma waves during six Mercury flybys from 2021 to 2025. Comparison with decades of GEOTAIL data showed

Scientists Predict Earth’s Rotation will Make Days 25 Hours Long

Astronomy, Science /

A study by researchers at the Technical University of Munich in Germany reports that Earth’s rotation is gradually slowing, and if this trend continues for millions of years, a day could eventually last 25 hours instead of 24. The study used a ring laser in southern Germany to detect tiny changes in Earth’s rotation. Over

Rocky Exoplanets Might be Shielded from Radiation by Magma Oceans

Astronomy, Planetary Science /

Far below the surface of distant super-Earth exoplanets, vast oceans of molten rock could be generating powerful magnetic fields capable of protecting the planets from hazardous cosmic radiation and other high-energy particles. Earth’s magnetic field arises from movements in its liquid iron outer core, a process called a dynamo. However, larger rocky planets like super-Earths

ISS Crew Safely Returns to Earth after a Medical Evacuation

Aerospace, Astronomy /

NASA footage showed four International Space Station crew members splashing down in the Pacific Ocean on Thursday following the first-ever medical evacuation in the station’s history. NASA video showed the capsule carrying American astronauts Mike Fincke and Zena Cardman, Russian cosmonaut Oleg Platonov, and Japanese astronaut Kimiya Yui touching down off the coast of San

Microgravity Spaceflight Causes Astronauts’ Brains to Shift and Deform

Astronomy, Planetary Science /

Spaceflight places significant physical strain on astronauts, leading to muscle loss, bone thinning, and fluid shifts. A new study in PNAS shows that microgravity also causes the brain to change shape. On Earth, gravity helps hold the brain in position, while surrounding cerebrospinal fluid cushions it. Scientists have long known that without gravity the brain

Assessing the Feasibility of Asteroid Mining: Insights from a New Study

Astronomy, Astrophysics /

A few years back, asteroid mining was a hot topic. As the commercial space sector expanded rapidly, turning space into a commercial frontier seemed within reach. The idea of using spacecraft to rendezvous with and mine Near-Earth Asteroids (NEAs) and then transport them to space-based processing facilities was almost as ambitious as sending commercial crews

Researchers Determine How Much Faster Time Moves on Mars

Planetary Science, Space & Environment /

A study by two physicists at the U.S. National Institute of Standards and Technology (NIST) found that, on average, clocks on Mars run about 477 microseconds faster per day than those on Earth. Although this time difference remains extremely small, it can significantly impact efforts to synchronize clocks precisely between Earth, the Moon, and Mars.

EscaPADE Is Intended to Carry Out Research On Mars

Astronomy, Planetary Science /

On November 13, the Escape and Plasma Acceleration and Dynamic Explorers (EscaPADE) mission was launched into space aboard Blue Origin’s New Glenn rocket. EscaPADE is a NASA mission made up of two identical spacecraft, each roughly a meter in size, called Blue and Gold. Its mission is to investigate the magnetic and plasma environment surrounding
