Astronaut Shubhanshu Shukla unveils BHEEM concept for setting up habitat on other planets

Astronaut Shubhanshu Shukla has developed a concept for extraterrestrial habitats. This modular design, named BHEEM, aims to support future human presence on other worlds. BHEEM addresses challenges like radiation and extreme temperatures for astronauts. Its panel-based architecture allows for easier construction and maintenance in space. This innovative habitat concept paves the way for India's space exploration goals.

In 2003, Nasa found freshwater snails reproduced in space with 50% larger statoconia

Nasa researchers observed freshwater snails reproducing in space during a Shuttle mission. Their gravity-sensing organs, called statoconia, grew substantially larger in microgravity. Swordtail fish larvae also developed enlarged otoliths, which are similar gravity-sensing stones. This indicated a critical developmental period where altered gravity impacts stone size. The findings suggest these organs regulate to achieve a functional weight.
