Black holes can be difficult to study, so researchers have made a powerful quantum vortex in a tank of superfluid helium that acts as a simulation of a black hole

Engineers at NASA’s Marshall Center successfully test-fired an innovative Rotating Detonation Rocket Engine combustor, a potentially revolutionary propulsion technology that could deliver a lander to the lunar surface or propel a spacecraft to Mars.

The Silurian hypothesis: would it be possible to detect an industrial civilization in the geological record? - Volume 18 Issue 2

"We argue the Lunar Anthropocene already has commenced, but we want to prevent massive damage or a delay of its recognition."

Projects to map the universe are getting weird.

Our space traffic management efforts need to improve.

Astronomers thought they had solved the mystery of gamma-ray bursts. A few recent events suggest otherwise.

In the past two decades, various space agencies have shown great enthusiasm for constructing habitable structures on lunar and Martian surfaces. Consequently, several extraterrestrial structures have been proposed by different researchers. Nevertheless, only a small number of those structures are energy-efficient and cost-effective. In this research, a comprehensive review of the proposed extraterrestrial structures has been conducted. The objective is to evaluate different habitat construction techniques from technical, economic, and energy-consumption perspectives. To carry this out, different proposed structures are elaborated, and their advantages and limitations are discussed. The primary focus is on the 3D printing technique, which has demonstrated significant potential in automated manufacturing tasks. From the conducted research, it was found that the combination of 3D-printed components along with an internal breathable inflatable module is the most promising technique for habitat development on the Moon and Mars. Moreover, the microwave sintering method was identified as the most energy-saving and reliable approach for melting the on-site regolith for use in the 3D printing process. This survey has applied a multidisciplinary approach to evaluate the most energy-saving planetary construction techniques that are economically crucial for different private or government-funded space agencies.

Decades after sending it to design purgatory, the space agency celebrates a logo it still calls the worm.
