Ground- and Space-Based Astronomy in the 2030s/2040s

Abstract

The three Astrophysics Program Analysis Groups (PAGs) – the Cosmic Origins Program Analysis Group (COPAG), the Exoplanet Exploration Program Analysis Group (ExoPAG), and the Physics of the Cosmos Program Analysis Group (PhysPAG) – have been asked to jointly report up to six community prioritized mission concepts, in addition to the X-ray and Far-IR flagship mission concepts recommended by Astro2020, to the NASA Astrophysics Division Director, for consideration for entrance into the ASTRA Initiative. These concepts should be selected in the context of the current and planned international suite of ground- and space-based observatories. In this talk we present results adapted from one of the Habitable Worlds Observatory (HWO) Community Working Groups, in which we lay out the context of ground- and space-based observatories and missions expected to operate in the 2030s/40s. We summarize outputs from our community-driven mission database, which outlines the science goals and capabilities of observatories and missions expected to operate during that time period. This information enables identification of synergies between these planned facilities and potential new concepts, as well as capability gaps in the planned suite of observatories that could be filled by entrants to the ASTRA Initiative.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
