Layering of lunar regolith at the Chandrayaan-3 landing site observed from the ChaSTE experiments from the lander

Abstract ChaSTE onboard the Vikram lander of the Chandrayaan-3 mission is designed for in-situ measurements of thermal conductivity (K) and temperature profiles of the lunar regolith with minimal disturbance. The thermal probe with 10 RTD sensors is used to measure continuous day...

Long‐term vertical air motion characteristics over the gateway of Indian summer monsoon using direct measurements by the Cochin stratosphere–troposphere radar

Abstract This article presents the first long‐term characteristics of vertical air motion over the gateway of Indian summer monsoon using the Cochin stratosphere–troposphere radar (10.04°N, 76.33°E). It is seen that the lower troposphere (<4 km) generally presents a downward mean...

Effect of Heating Rate on the One‐Pot Synthesis of ZrB 2 –ZrC–SiC Ceramics by PDC Route

ABSTRACT Zirconoborosiloxane (ZBS), a preceramic oligomer, was synthesized by a nonaqueous sol–gel route in our earlier work, which yields ceramics of m‐ZrO 2 , ZrSiO 4 , and t‐ZrO 2 upon pyrolysis at 1500°C and 1650°C in argon. In the present study, a single system comprised of...

Plasma Turbulence in the Lunar Environment Across Solar Wind and Magnetotail Conditions: Observations From Chandrayaan‐2 Radio Science Experiment

Abstract The Moon's transit between the solar wind and Earth's magnetotail exposes the near‐lunar environment to large and rapid variations in plasma density and flow structure. Two‐way coherent S‐band radio occultation measurements from Chandrayaan‐2 were used to quantify electr...

Mechanical characterization of 18% Ni maraging steel welds produced by cold wire and hot wire gas tungsten arc welding

Maraging steels are a distinct class of ultra-high-strength alloys extensively employed in the fabrication of solid rocket motor casings. These casings are typically manufactured in segmented form, with the desired mechanical properties achieved through controlled ageing heat tre...
