Statistically Speaking, We Should Have Heard from Aliens by Now May 7, 2025
The Fermi Paradox presents us with a striking contradiction: despite the high probability of numerous civilizations existing throughout the Universe, we've encountered no evidence or communication from any alien intelligence. A new paper just published calculates that we should have a 99% chance of detecting at least one signal from another civilisation—assuming they survive for […]

On May 7th, the Japanese space exploration company ispace announced that its HAKUTO-R RESILIENCE lander entered lunar orbit after completing a 9-minute thruster burn. It's now in a stable lunar orbit, and operators will spend the next month testing and preparing for its landing attempt on June 5. This is the company's second attempt at […]
Uh Oh, There's a Problem With Psyche's Propulsion System May 7, 2025
NASA’s Psyche mission is on its way to explore a metal-rich asteroid in the asteroid belt between Mars and Jupiter. All was going well since its launch in October 2023 until nasa announced a decrease in fuel pressure for the propulsion system. It uses a solar electric propulsion system, generating thrust with four electric ion […]
Could Sweating Spacecraft Make Re-Entry Easier? May 7, 2025
When ISS astronauts return home, they have a hot ride back to Earth's surface. It's been that way since the beginning of human spaceflight to orbital space and beyond. The incoming vehicle uses friction with Earth's atmosphere to slow down to a safe landing speed. The "hot ride" part comes because that friction builds up […]
A Collaboration Between China and the West Could Find Dozens of Earth-Like Worlds May 7, 2025
If astronomy has a Holy Grail, it's another habitable world. To find one, NASA is working with partners to develop the Habitable Worlds Observatory (HWO). The HWO would be the first telescope built to detect Earth-like planets around Sun-like stars. China is building the Closeby Habitable Exoplanet Survey (CHES), and new research shows that by […]
