Spaceplane Spectacle: Dream Chaser Endures NASA’s Ultimate Trial

Posted by in category: space travel

The Dream Chaser spaceplane, developed by Sierra Space and undergoing testing at NASA ’s Armstrong Test Facility, is set for its first demonstration flight to the ISS. This marks a significant step in the commercial resupply program and underscores the ongoing space industrial revolution, aimed at enhancing human life on Earth.

Nose-up and bathed in soft blue lights, Sierra Space’s Dream Chaser spaceplane and its Shooting Star cargo module cast dramatic shadows onto the walls of NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, as members of the media got their first glimpse of the towering 55-foot-tall stack on February 1.

Tesla Cybertruck range test reveals impressive distance on full charge

Posted by in category: transportation

Tesla Cybertruck range tests are all the buzz, and publications are looking to see how accurate the automaker’s projections and estimates are, and how many miles the all-electric pickup can travel on a full charge.

A few tests have already been performed, including one that took the Cybertruck on the highway and gave less-than-favorable results.

However, range tests are never identical because so many external factors, like driving style and temperature, for example, can significantly influence the results.

Newly discovered Carbon Monoxide-Runaway Gap can help Identify Habitable Exoplanets

Posted by in categories: alien life, chemistry, climatology

The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet’s position in the habitable zone, the region around a star where liquid water could potentially exist on the planet’s surface. NASA’s Kepler telescope, launched in 2009, revealed that 20–50% of visible stars may host such habitable Earth-sized rocky planets. However, the presence of liquid water alone does not guarantee a planet’s habitability. On Earth, carbon compounds such as carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO) played a crucial role in shaping the climate and biogeochemistry and could have contributed to the emergence of life.

Taking this into consideration, a recent study by Associate Professor Kazumi Ozaki from Tokyo Institute of Technology, along with Associate Researcher Yasuto Watanabe from The University of Tokyo, aims to expand the search for habitable planets. Published in the Astrophysical Journal(External site) on 10 January 2024, the researchers used atmospheric modeling to identify conditions that could result in a CO-rich atmosphere on Earth-like planets that orbit sun-like (F-, G-, and K-type) stars. This phenomenon, known as CO runaway, is suggested by atmospheric models to have possibly occurred in early planetary atmospheres, potentially favoring the emergence of life.

“The possibility of CO runaway is critical in resolving the fundamental problem regarding the origin of life on Earth because various organic compounds suitable for the prebiotic chemistry are more likely to form in a CO-rich atmosphere than in a CO2-rich atmosphere,” explains Dr. Ozaki.
