New Research Suggests Mars Stayed Habitable Longer than Once Thought

Satellites Tech, Space & Environment / Ana Kiesse Zeleme

Scientists widely agree that Mars once had flowing water and a thicker atmosphere, conditions that would have made the planet habitable. But between about 4.2 and 3.7 billion years ago, its rivers, lakes, and global ocean vanished as the solar wind gradually eroded the atmosphere. Exactly how long Mars stayed habitable remains an open question. […]

The Challenges and Triumphs of Space Research

Astronomy, Space & Environment / Jorge Paka

The microgravity encountered during spaceflight can threaten astronauts’ cardiovascular health. Finding effective ways to reduce these risks is difficult because countermeasures are typically evaluated under Earth’s gravity. But what if research could be conducted in microgravity conditions without having to leave the atmosphere? Texas A&M Researchers Test Microgravity in France Researchers from Texas A&M University

Scientists Create a Spacesuit with Artificial Muscles to Reduce Astronaut Strain

Aerospace, Space & Environment / Jorge Paka

A new textile-based exoskeleton from the University of Bristol could transform mobility in space and support people with disabilities on Earth. Scientists in England developed a prototype exosuit with artificial muscles to ease astronaut movement and reduce fatigue in low-gravity environments like the Moon or Mars. Innovation Driven by VIVO Hub’s Interdisciplinary Research VIVO Hub,

NASA Unveils Photos Depicting Two Supermassive Black Holes Coming Together

Aerospace, Space & Environment / Ngoma Manuel

In a newly released image from NASA, the galaxy known as NGC 6240 features two supermassive black holes currently merging. The image combines fresh X-ray data from the Chandra Observatory (displayed in red, orange, and yellow) with an optical image captured by the Hubble Space Telescope, first published in 2008. The two merging black holes,

China’s Chang’e-6 mission — the first to bring back samples from the Moon’s far side — made an intriguing discovery last year. After examining the lunar samples returned in June, scientists found fragments of CI chondrite — a rare, water-rich meteorite seldom surviving Earth’s atmosphere, ScienceAlert reports. This marks the first detection of CI chondrite

How Smartphones are Revealing the True Patterns of Urban Movement

Geographical Tech, Tech / Eduardo Paulo

When I started my Ph.D. in Boston, I quickly realized how limited and outdated our data is on urban mobility. We often talk about “car dependence,” “walkable neighborhoods,” or “transit equity,” but self-reported surveys that people complete—often outdated by years—usually provide the information behind these terms. These surveys typically ask people to remember every trip

James Webb Warns 31/Atlas Approaching Earth — Should we Worry?

Satellites Tech, Space & Environment / Jorge Paka

By nature, scientists can’t predict what they’ll uncover while studying the interstellar object 3I/ATLAS — only the third ever detected from beyond our solar system. Yet, the surprises keep piling up. First spotted racing toward the Sun in early July, 3I/ATLAS has captivated researchers. Science Alert reports that four major observatories — Hubble, SPHEREx, TESS,

NASA Research Reveals That The Sun’s Activity Is Intensifying

Astronomy, Planetary Science, Space & Environment / Jorge Paka

A recent NASA study shows that the Sun has been growing more active since 2008. While solar activity typically follows 11-year cycles, it also experiences longer-term shifts that can span decades. For example, solar activity had been steadily declining since the 1980s, reaching a record low in 2008. At the time, scientists believed the Sun

NASA Rover Finds Possible Evidence of Ancient Life on Mars

Aerospace, Space & Environment / Jorge Paka

Over four years after landing, NASA’s Perseverance Rover may have made key progress in its search for ancient microbial life. In July, the rover found an arrowhead-shaped rock called Cheyava Falls, with colorful patches in a valley likely carved by water. Possible Microbial Traces Spark Debate, NASA Shares Findings for Wider Review NASA scientists suspect

ORNL Confronts the Control Challenges of Nuclear Rocket Engines

Aerospace, Space & Environment / Samilton Santos

How do you manage a nuclear propulsion system in space? The answer is: with extreme care. To address this, researchers at Oak Ridge National Laboratory (ORNL) have created a simulated nuclear reactor test platform designed to advance the development of engines capable of taking astronauts to Mars and beyond.
