An exciting and novel science mission concept called Seismic and Atmospheric Exploration of Venus (SAEVe) has been developed which uses high-temperature electronics to enable a three-order magnitude increase in expected surface life (120 Ea...
The electrostatic plasma environment of a small airless body under non-aligned plasma flow and UV conditions [0.03%]
非对准等离子体流和紫外线条件下小型无大气天体的静电环境研究

A R Poppe et al.
Airless bodies interact with a wide variety of plasma environments throughout the solar system. For many objects, incident plasma is nearly co-aligned with solar ultraviolet radiation leading to the development of a positively charged daysi...
Automated Detection of Meteorite Strewnfields in Doppler Weather Radar [0.03%]
doppler天气雷达中的陨石雨的自动检测

A survey around a recently-fueled MMRTG in the terrestrial atmosphere finds a warm air plume with a characteristic updraft velocity of ~1 m/s and a temperature rise of ~4 K. Additionally, a roughly hundredfold enhancement in ion density t...
Excess of L-alanine in amino acids synthesized in a plasma torch generated by a hypervelocity meteorite impact reproduced in the Laboratory [0.03%]
实验室再现超高速陨石撞击产生的等离子体火炬中合成的氨基酸中L-丙氨酸过剩现象

We present our method to calculate the meteor limiting magnitude. The limiting meteor magnitude defines the faintest magnitude at which all meteors are still detected by a given system. An accurate measurement of the limiting magnitude is i...
Isotopic constraints on the source of Pluto's nitrogen and the history of atmospheric escape [0.03%]
