Two papers co-authored by MSFC scientists have been accepted for publication by the SPIE Journal of Astronomical Telescopes and Instrument Systems. The first paper is "Habitable-Zone Exoplanet Observatory (HabEx) baseline 4-m telescope: systems-engineering design process and predicted structural thermal optical performance", by H. Philip Stahl (MSFC), Gary Kuan (JPL), William R. Arnold (MSFC/TBE), Thomas Brooks (MSFC), J. Brent Knight (MSFC), and Stefan Martin (JPL), https://doi.org/10.1117/1.JATIS.6.3.034004.
