This review discusses the magnitude of the cosmic dust input into the earth's atmosphere,
and the resulting impacts from around 100 km to the earth's surface. Zodiacal cloud …

The paper reviews the aspects of cosmic dust that are important to its collection and
utilization as a resource of extraterrestrial material. Most of the collected dust particles …

Large increases in the number of low earth orbit satellites are projected in the coming
decades [L. Schulz, K.-H. Glassmeier, Adv. Space Res. 67, 1002–1025 (2021)] with perhaps …

This is the fifteenth in a series of evaluated sets of rate constants and photochemical cross
sections compiled by the NASA Panel for Data Evaluation. The data are used primarily to …

Some of the global warming from anthropogenic greenhouse gases is offset by increased
reflection of solar radiation by clouds with smaller droplets that form in air polluted with …

Updated chemical schemes and estimates of key rate coefficients are used in the present
investigation of the photochemistry of Titan atmosphere CH-and O-atom containing simple …

In situ measurements of the chemical composition of individual aerosol particles at altitudes
between 5 and 19 kilometers reveal that upper tropospheric aerosols often contained more …

Some theories for the observed anomalous radar backscatter during the summer (polar
mesospheric summer echoes, or PMSE) and electron bite outs measured by rockets require …

In the 1990s, nanoparticles and quantum dots began to be used in optical, electronic, and
biological applications. Now they are being studied for use in solid-state quantum …

We review the major impact‐associated mechanisms proposed to cause extinctions at the
Cretaceous‐Tertiary geological boundary. We then discuss how the proposed extinction …
