A Twenty Year Decline in Solar Photospheric Magnetic Fields: Inner-Heliospheric Signatures and Possible Implications?
P. Janardhan, Susanta Kumar Bisoi, S. Ananthakrishnan +4
We report observations of a steady 20 year decline of solar photospheric fields at latitudes 45 starting from 1995. This prolonged and continuing decline, combi…
Spatial heterogeneity in the radiogenic activity of the lunar interior: Inferences from CHACE and LLRI on Chandrayaan-1
R. Sridharan, Tirtha Pratim Das, S. M. Ahmed +3
In the past, clues on the potential radiogenic activity of the lunar interior have been obtained from the isotopic composition of noble gases like Argon. Excess Argon (40) relative…
Extremely high reflection of solar wind protons as neutral hydrogen atoms from regolith in space
Martin Wieser, Stas Barabash, Yoshifumi Futaana +7
We report on measurements of extremely high reflection rates of solar wind particles from regolith-covered lunar surfaces. Measurements by the Sub-keV Atom Reflecting Analyzer (SAR…
Studying the Lunar-Solar Wind Interaction with the SARA Experiment aboard the Indian Lunar Mission Chandrayaan-1
Anil Bhardwaj, Stas Barabash, M. B. Dhanya +7
The first Indian lunar mission Chandrayaan-1 was launched on 22 October 2008. The Sub-keV Atom Reflecting Analyzer (SARA) instrument onboard Chandrayaan-1 consists of an energetic…
The Sub-keV Atom Reflecting Analyzer (SARA) Experiment Aboard Chandrayaan-1 Mission: Instrument and Observations
Anil Bhardwaj, Martim Wieser, M. B. Dhanya +7
SARA experiment aboard the first Indian lunar mission Chandrayaan-1 had the objective to explore the solar wind-lunar interaction using energetic neutral atoms (ENA) from the lunar…
Protons in the near-lunar wake observed by the Sub-keV Atom Reflection Analyzer on board Chandrayaan-1
Yoshifumi Futaana, Stas Barabash, Martin Wieser +7
Significant proton fluxes were detected in the near wake region of the Moon by an ion mass spectrometer on board Chandrayaan-1. The energy of these nightside protons is slightly hi…
