The observatories and instruments that will be able to perform transmission spectroscopy of exo- Earths are beginning to be planned, and exhaustively characterizing the spatially-integrated transmission spectrum of Earth is key to ensuring that key spectral features (e.g., ozone) are appropriately captured in mission concept studies. Ozone is photochemically produced from O2, a product of the dominant metabolism on Earth today. It will therefore be sought in future observations as critical evidence for life on exoplanets. Ground-based lunar eclipse observations have provided the Earth's transmission spectrum at optical and near-IR wavelengths, and this program will extend Earth's measured transmission spectrum into the UV. The strongest expected signals are from ozone, CO2, and N2 (via Rayleigh scattering), with weaker signals from ionospheric species like Ca II and Mg II. The resulting Earth transmission spectrum will also be compared to the Venus transmission spectrum that was observed in during the 2012 Venus transit with a similar HST STIS configuration. The ability to distinguish Earth-like and Venus-like terrestrial exoplanets via transmission spectroscopy is of great importance to future missions targeting direct detection of inhabited planets, and ozone is an important gas to consder in the search for life elsehwere in the universe. We will observe the penumbral and umbral phases of the total lunar eclipse on Jan 21, 2019 with the STIS spectrograph. More details to be filled in.
