Future spacecraft may travel farther by drawing momentum from planets, sunlight, and the solar wind instead of onboard fuel. Every conventional rocket faces the same problem: it must carry the material that propels it. Since Konstantin Tsiolkovsky described the rocket equation in 1903, spacecraft have burned fuel and expelled it backward to move forward under […]
The Propellantless Spacecraft Technologies That Could Help Us Reach the Stars
Future spacecraft may travel farther by drawing momentum from planets, sunlight, and the solar wind instead of onboard fuel. Every conventional rocket faces the same problem: it must carry the material that propels it.

China’s Tianwen-1 Captures Rare Close-Up Images of Interstellar Comet 3I/ATLAS
China’s Tianwen-1 orbiter caught a rare glimpse of 3I/ATLAS as it swept past Mars, revealing the hazy coma and tail of a comet born beyond our solar system. The interstellar object known as 3I/ATLAS just flew past Mars, and China’s Tianwen-1 mission managed to snap some pics with its high-resolution camera. According to the China […]
Second PSMA PET Scan Finds Hidden Prostate Cancer in 56% of Patients
A negative scan does not always mean recurrent prostate cancer is nowhere to be found. Sometimes, the disease may simply be too small or too faint to appear yet. New research suggests that repeating a PSMA PET scan later can reveal cancer that was missed the first time. Among patients with rising prostate-specific antigen (PSA) […]
