Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Magnetohydrodynamic Instabilities of Double Magnetic Bands in a Shallow-water Tachocline Model. II. Teleconnection Between High- and Low-latitude Bands and Across Equator

The Astrophysical Journal
The “extended solar cycle” indicates that there are two deeply seated toroidal magnetic field bands in each hemisphere. Both bands migrate equatorward as a sunspot cycle progresses.

Differential Rotation in the Solar Interior [PDF]

International Astronomical Union Colloquium, 1970
One of the big problems in stellar rotation which has been the object of much debate recently concerns the magnitude of the angular velocity in the central regions of the sun. It is a good example of our general ignorance of the distribution of angular momentum in the interiors of stars. There is good reason, of course, for this ignorance.

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters
Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic ...
