IMPRESS: A Planetary Penetrator Network for Astrobiology, Prospecting, and Exploration of Mars

Jan Špaček, Holden Alpern, T E Dineen, Janusz Jurand Petkowski et autres

The International Mars Prospecting Ride-Share System (IMPRESS) is presented here as a scalable, democratized, and low-cost mission architecture for distributed measurements on the martian surface and in the shallow subsurface. IMPRESS is intended to prospect on Mars in advance of sample return …

A long-lived impact-generated hydrothermal system at the Chicxulub impact structure

Annemarie Pickersgill, E. V. Christou, Marissa Marie Tremblay, Dan N. Barfod et autres

Hydrothermal systems likely played an essential role in the origin of life, both on Earth and potentially on other planets. They form anywhere that heat and aqueous fluids interact, including within cooling hypervelocity impact craters. Longer periods of hydrothermal activity will generate …

Terrestrial Analogs to Titan for Geophysical Research

Conor A. Nixon, Samuel Birch, Audrey Chatain, Charles Cockell et autres

Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas - methane - replacing the Earth's water, …

Antarctic snow algal responses to temperature - potential implications of climate change

Carla Ruiz Gonzalez, Vaila Grigg, Naomi J. Thomas, Alex Thompson et autres

Abstract Snow algae are important primary producers in Antarctic terrestrial ecosystems. As short-term Antarctic summer temperatures approach 20°C, parameterising temperature tolerance for snow algal species is key to determining how climate change may affect community composition and primary productivity. We studied three …

The EChO science case

G. Tinetti, P. Drossart, Paul Eccleston, P. Hartogh et autres

The discovery of almost two thousand exoplanets has revealed an unexpectedly diverse planet population.We see gas giants in few-day orbits, whole multi-planet systems within the orbit of Mercury, and new populations of planets with masses between that of the Earth and Neptune-all …
