In an important breakthrough for nuclear astrophysics, an international team led by HOU Suqing from the Institute of Modern Physics of the Chinese Academy of Sciences has successfully derived a new reaction rate for a crucial component of the rapid proton capture process (rp-process). Their findings were recently published in The Astrophysical Journal.

NASA power outage temporarily halts contact with space station
Tuesday, 25 July 2023 19:53 Write a comment
A NASA power outage disrupted communication between Mission Control and the International Space Station on Tuesday.
Mission Control couldn't send commands to the station and talk with the seven astronauts in orbit. The power outage hit as upgrade work was underway in the building at Houston's Johnson Space Center.
Space station program manager Joel Montalbano said neither the astronauts nor station were ever in any danger and that backup control systems took over within 90 minutes.
An 800-year-old mathematical trick could help with lunar navigation
Tuesday, 25 July 2023 19:34 Write a comment
Kamilla Cziráki, a geophysics student at the Faculty of Science of Eötvös Loránd University (ELTE), has taken a new approach to researching the navigation systems that can be used on the surface of the moon to plan future journeys.
Working with Professor Gábor Timár, head of the Department of Geophysics and Space Sciences, Cziráki calculated the parameters used in the Earth's GPS system for the moon using the method of mathematician Fibonacci, who lived 800 years ago. Their findings have been published in the journal Acta Geodaetica et Geophysica.
Now, as humanity prepares to return to the moon after half a century, the focus is on possible methods of lunar navigation.

Tuesday, 25 July 2023 08:37 Write a comment
The cosmic lineage of the second-generation carbonaceous asteroid Ryugu can be traced back to a distant past and a far-flung location in our solar system, according to recent studies on the space rock's anhydrous minerals. The infrared spectra of these grains provide a link between the initial reservoirs, from which Ryugu's progenitor arose, and those that birthed primitive asteroids and comets
