The Star-Planet Activity Research CubeSat (SPARCS): Determining Inputs to Planetary Habitability
David R. Ardila, Evgenya Shkolnik, Paul Scowen +19
Seventy-five billion low-mass stars in our galaxy host at least one small planet in their habitable zone (HZ). The stellar ultraviolet (UV) radiation received by the planets is str…
Community Report from the Biosignatures Standards of Evidence Workshop
Victoria Meadows, Heather Graham, Victor Abrahamsson +72
The search for life beyond the Earth is the overarching goal of the NASA Astrobiology Program, and it underpins the science of missions that explore the environments of Solar Syste…
The UV-SCOPE Mission: Ultraviolet Spectroscopic Characterization Of Planets and their Environments
David R. Ardila, Evgenya Shkolnik, John Ziemer +22
UV-SCOPE is a mission concept to determine the causes of atmospheric mass loss in exoplanets, investigate the mechanisms driving aerosol formation in hot Jupiters, and study the in…
Onboard Dynamic Image Exposure Control for the Star-Planet Activity Research CubeSat (SPARCS)
Tahina Ramiaramanantsoa, Judd D. Bowman, Evgenya L. Shkolnik +19
The Star-Planet Activity Research CubeSat (SPARCS) is a 6U CubeSat under development to monitor the flaring and chromospheric activity of M dwarfs at near-ultraviolet (NUV) and far…
Time-Resolved Photometry of the High-Energy Radiation of M Dwarfs with the Star-Planet Activity Research CubeSat (SPARCS)
Tahina Ramiaramanantsoa, Judd D. Bowman, Evgenya L. Shkolnik +18
Know thy star, know thy planet,... especially in the ultraviolet (UV). Over the past decade, that motto has grown from mere wish to necessity in the M dwarf regime, given that the…
Venus as a Nearby Exoplanetary Laboratory
Stephen R. Kane, Giada Arney, Paul Byrne +9
The key goals of the astrobiology community are to identify environments beyond Earth that may be habitable, and to search for signs of life in those environments. A fundamental as…
Exoplanets in our Backyard: A report from an interdisciplinary community workshop and a call to combined action
Giada N. Arney, Noam R. Izenberg, Stephen R. Kane +5
This is a white paper submitted to the Planetary Science and Astrobiology Decadal Survey. The Exoplanets in our Backyard meeting was born out of a recognition of the value and pote…
The Star-Planet Activity Research CubeSat (SPARCS): A Mission to Understand the Impact of Stars in Exoplanets
David R. Ardila, Evgenya Shkolnik, Paul Scowen +14
The Star-Planet Activity Research CubeSat (SPARCS) is a NASA-funded astrophysics mission, devoted to the study of the ultraviolet (UV) time-domain behavior in low-mass stars. Given…
Terrestrial Planet Finder Coronagraph (TPF-C) Flight Baseline Concept
Marie Levine, D. Lisman, S. Shaklan +52
The Terrestrial Planet Finder Coronagraph (TPF-C) mission presented here is an existence proof for a flagship-class internal coronagraph space mission capable of detecting and char…
