Scientists have grown chickpeas in simulated moon soil, offering a promising step toward farming on the lunar surface. Researchers mixed moon-like regolith with worm-produced compost and helpful fungi that protect plants from toxic metals. The combination allowed chickpeas to grow and produce a harvest in soil that normally cannot supportContinue Reading
The Cygnus XL cargo spacecraft, with its prominent cymbal-shaped UltraFlex solar arrays, departs the International Space Station after its release from the Canadarm2 robotic arm. NASA+ At 7:06 a.m. EDT, Northrop Grumman’s Cygnus XL was released from the Canadarm2 robotic arm, which earlier detached the cargo spacecraft from the Earth-facingContinue Reading
Northrop Grumman’s Cygnus XL cargo craft is pictured in the grips of the Canadarm2 robotic arm following its capture on Sept. 18, 2025. Cygnus XL is Northrop Grumman’s expanded version of its previous Cygnus cargo craft increasing its payload capacity and pressurized cargo volume. NASA Live coverage of the departureContinue Reading
