Unveiling the Rotten Egg Nebula The "Rotten Egg Nebula" is a unique protoplanetary nebula resulting from the remnants of the red giant OH231.8+4.2. Situated in the Canis Major constellation, it stands out due to the high presence of hydrogen sulfide and sulfur dioxide molecules surrounding the star in transition. This peculiar name derives from the distinctive chemical composition surrounding the evolving star. Typically, a full-fledged planetary nebula emerges approximately 1000 years after this initial stage in the nebula's evolution.

Lunar Lander Blue Ghost Completes Ground Rehearsal The lunar lander Blue Ghost recently finished a successful ground rehearsal for its rocket launch. The tests took place at the Jet Propulsion Laboratory's Environmental Test Lab in California, the same facility that prepared Voyager probes for their historic journey beyond the Solar System. In preparation for the launch, the mock-up of the lander was subjected to extreme conditions by being secured on a vibrating platform and placed inside an acoustic chamber to simulate the rigors of the upcoming rocket launch.

Rostec Reveals Hot-Fire Stand Tests of RD-107A and RD-108A Engines The recently released footage showcases the hot-fire stand tests of RD-107A and RD-108A engines, crucial components utilized in the Soyuz-2.1a and Soyuz-2.1b carrier rockets. These tests rigorously evaluate various parameters such as thrust, fuel system efficiency, turbo pump performance, vibrational stress resistance, temperature tolerance, and time characteristics. Following the tests, the engines undergo disassembly, cleaning, and meticulous preparation for integration with the carrier rockets.

Robot "Teledroid" to Support Astronauts in Space The robot, resembling a human torso with a head and arms but no legs, is tailored for tasks on the station's exterior. "Teledroid" will handle tools and execute standard operations. The system, constructed with Russian components, functions in three modes. The flight model is presently undergoing testing at TsNIImash. Plans are set to launch the equipment into orbit starting in June 2026.
