In this work we discuss various selected mission concepts addressing Venus evolution
through time. More specifically, we address investigations and payload instrument concepts …

Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients
to build habitable worlds like Earth, but their origin and evolution on terrestrial planets …

The origin of Earth's water remains unknown. Enstatite chondrite (EC) meteorites have
similar isotopic composition to terrestrial rocks and thus may be representative of the …

We report the first detection in the interstellar medium (ISM) of a C 2 H 5 O 2 N isomer: syn-
glycolamide (NH 2 C (O) CH 2 OH). The exquisite sensitivity at sub-mK levels of an …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

Comets are considered to be some of the most pristine and unprocessed Solar system
objects accessible to in situ exploration. Investigating their molecular and elemental …

In situ research of cometary chemistry began when measurements from the Giotto mission at
Comet 1P/Halley revealed the presence of complex organics in the coma. New telescopes …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

Atmospheric xenon is strongly mass fractionated, the result of a process that apparently
continued through the Archean and perhaps beyond. Previous models that explain Xe …

Earth's origins are challenging to elucidate, given the lack of surviving terrestrial geology
from the first 500 Myr of the Solar System. In this Review, we discuss breakthroughs in …
