GUSTO:  A Balloon-Borne TeraHertz Observatory [#5019]
GUSTO is a balloon-borne terahertz observatory selected as a NASA Mission of Opportunity. It will survey 124 square degrees of the Milky Way and all of the LMC in [CII], [OI], and [NII]. GUSTO will fly in December 2021.

ATLAS Probe:  Breakthrough Science of Galaxy Evolution, Cosmology, Milky Way, and the Solar System [#5003]
ATLAS Probe is the spectroscopic follow-up mission to WFIRST designed for transformative science over the entire range of astrophysics, on a 1.5m telescope with FoV 0.4 sq deg that takes >5000 slit spectra simultaneously at R = 1000 over 1–4 microns.

Probe of Inflation and Cosmic Origins (PICO) Science Objectives [#5052]
PICO is a Probe class (<$1B) space mission concept providing full sky temperature and polarization mapping in 20–800 GHz bands. This poster describes the science objectives. A companion poster (Trangsrud et al.) describes the engineering implementation.

Origins Space Telescope:  The Heterodyne Receiver (HERO) [#5032]
The Heterodyne Receiver for OST (HERO) is a very high spectral resolution (??/? =10-7, or ?v = 0.03 km/s) instrument for the Origins Space Telescope (OST) and complements OST’s incoherent mid- to far-IR spectrometers.

Time Domain Astronomy with Fermi GBM in the Multimessenger Era [#5071]

The Fermi GBM is the most prolific detector of short gamma-ray bursts. I will describe searches for GRB 170817A-like events in archival data and plans to find more coincident events in the future, starting with LIGO/Virgo's third observing run.

Development of a CsI:Tl Calorimeter Subsystem for the All-Sky Medium-Energy Gamma-Ray Observatory (AMEGO) [#5016]
We report on the development of the CsI calorimeter subsystem for the All-Sky Medium-Energy Gamma-ray Observatory (AMEGO). We will show data from the lab and a beam test, and discuss preparation for the next beam test and a balloon flight.

Next Generation Astronomical X-Ray Optics:  High Resolution, Light Weight, and Low Cost [#5024]
We report on our effort to develop an X-ray mirror technology that has four highly desired characteristics:  (1) Angular resolution, (2) Lightweight (or large effective area), (3) Large field of view, and (4) Low production cost.
