RSAA Colloquium: Erika Hamden (U.Arizona)

Discovery potential in the era of Small Sats.

It’s never been easier to launch something into space. It’s never been cheaper to get a spacecraft. In this new era of space accessibility, the astronomical community has an exciting opportunity to advance space sciences through small payloads and telescopes on small sats.

Description

Discovery potential in the era of Small Sats

It’s never been easier to launch something into space. It’s never been cheaper to get a spacecraft. In this new era of space accessibility, the astronomical community has an exciting opportunity to advance space sciences through small payloads and telescopes on small sats. In this talk, I will describe a bit about the current landscape, provide some examples from a cost and schedule perspective, and describe my own involvement in several smaller missions, both at the concept stage and being built. I will touch on how missions of this type can contribute to science questions across astronomy, with a focus on my own interests in CGM science and molecular cloud lifetimes and formation, and how those interests can be explored now with smallsats. I will focus especially on the Aspera Mission, a $20M USD mission funded by NASA to observe nearby galaxy circumgalactic media via extreme ultraviolet OVI emission.
