“…Although the C-X transition has a similar inherent strength as the A-X transition (T00=23173 cm -1 ), the latter has been of more utility for astronomers due to the accessibility and higher radiation flux in the visible spectral region [11]. The work on the C-X system may become beneficial when more sensitive UV telescopes, such as the World Space Observatory-Ultraviolet (WSO-UV) [41] come online or for measurements of sources that are brighter in the UV or where CH is more thermally excited. The bands reported here, also coincide with a wavelength domain in which diffuse interstellar band (DIBs) spectra along many different lines of sight have become available [42] and the search for excited CH transitions may be helpful in further constraining the processes involved in the formation of DIB carriers.…”

Rotationally resolved spectra of the C 2 Σ + -X 2 Π electronic system of the CH radical were measured using cavity ring-down spectroscopy in supersonically expanding, planar hydrocarbon plasma. The experimental conditions allowed the study of highly excited rotational levels starting from vibrationally excited states. Here we present some 200+ new or more accurately recorded transitions in the 0-0, 1-1 and 2-2 vibronic bands in the ultraviolet between 30900-32400 cm -1 (324-309 nm). The resulting data, compared to earlier measurements, allows for the determination of more precise molecular constants for each vibrational state and therefore more precise equilibrium values. From this an equilibrium bond length of 1.115798(17) Å for the C 2 Σ + state is determined. A comprehensive list with observed transitions for each band has been compiled from all available experimental studies and constraints are placed on the predissociation lifetimes.

“…the baseline MCP detector is currently under development for the WSO-UV mission 40 and it is based on the heritage of the ISSIS instrument 41 though its QE has been enhanced to reach the sensitivity of the Hamamatsu detectors used in the Lyman Alpha Imaging Camera (LAICA) on board the Japanese micro-spacecraft PROCYON 5 with a rather similar optical configuration. 42 Similar results have also been obtained by SOHO/SWAN.…”

There is a growing interest in Lunar exploration fed by the perception that the Moon can be made accessible to low-cost missions in the next decade. The on-going projects to set a communications relay in Lunar orbit and a deep space Gateway, as well as the spreading of commercial-of-the shelf (COTS) technology for small space platforms such as the cubesats contribute to this perception. Small, cubesat size satellites orbiting the Moon offer ample opportunities to study the Moon and enjoy an advantage point to monitor the Solar System and the large scale interaction between the Earth and the solar wind. In this article, we describe the technical characteristics of a 12U cubesat to be set in polar Lunar orbit for this purpose and the science behind it. The mission is named EarthASAP (Earth AS An exoPlanet) and was submitted to the Lunar Cubesats for Exploration (LUCE) call in 2016. EarthASAP was designed to monitor hydrated rock reservoirs in the Lunar poles and to study the interaction between the large Earth's exosphere and the solar wind in preparation for future exoplanetary missions. Gateway 2 has open the path to the development of lunar cubesats. This new generation will need to confront important challenges such as the adaptation to interplanetary space or the development of communication strategies based on shared communications relays. Moon's orbit offers ample opportunities to study the Moon and enjoys an advantage point to monitor the the Solar System and the large scale interaction between the Earth and the solar wind. In recognition of this interest, the European Space Agency (ESA) focused the 2016 SysNova call on lunar cubesats (LUCE); ESA's SysNova calls open regularly 3 aiming at getting innovative proposals in space technology. LUCE Sysnova technical challenge was intended to address four different topics: lunar resource prospecting, environment and effects, science from or in the Moon and lunar exploration technology and operations demonstration. The first version of the project we present in this article was submitted to this call, though it was not selected it evolved and matured to address some critical challenges such as the required instrument miniaturization, the propulsion for orbit maintenance or the on-board autonomy assuming sparse communication windows to an international communication relay. The project was named Earth AS An exo-Planet (EarthASAP)as one of its key scientific objectives is using the lunar orbit vantage point to monitor the interaction between the Earth's exosphere and magnetosphere with the solar wind; also in preparation for the coming exoplanetary research missions.In the following sections the scientific objectives (section 2), the mission concept (section 3), the mission and data handling (section 4) are described. The article concludes with a brief summary together with the risk evaluation and the palliative solutions proposed by the team (section 5). 2 exploration.esa.int/moon/59374-overview/ 3 gsp.esa.int/sysnova

“…As today, the only 2-m class observatory in development is the World Space Observatory-Ultraviolet (WSO-UV) to be launched in few years (Shustov et al, 2018). WSO-UV is the international name of Spectrum-UV, the observatory of the series Spectrum being part of the scientific program of the Russian Space Agency.…”

This contribution to the Research Topic "Imagining the Future of Astronomy and Space Sciences" focuses on astrobiology and exoplanetary research. Understanding the origin of life is the main scientific challenge to this century and an interdisciplinary endeavor in itself. To that astronomy will contribute in three key issues. Firstly, by measuring the abundance of elements relevant to life in the Universe. Then by determining the preferred location for aminoacids and complex organic molecules assembly. Finally, by investigating the signatures of life in exoplanets. A new generation of facilities will need to be built to address these questions. The relevance of ultraviolet instrumentation for this purpose is highlighted in this short perspective.
