[1][2] The first task considers observations of the Solar System planets, moons, and the asteroid belt to explore processes necessary for habitable environments and for exoplanet model confirmation.
Specifically, observations of Europa,[3] Venus,[4] Earth,[5] Mars, and the asteroid belt have helped researchers in Task A address their goals.
Task B combines geological and biological data[6] with ecosystem[7] and photo-chemical models[8][9] to showcase how planet Earth has changed throughout its history.
Task D incorporates VPL researchers from diverse and interdisciplinary fields who use laboratory work[13][14] combined with chemical and climate models to study the impact of life on its environment.
In addition, VPL members use telescope and instrument simulators to study which measurements, observing strategies, and analysis techniques are necessary for the characterization of exoplanets.
