An updated alignment strategy for the off-plane grating rocket experiment (OGRE)
On demand | Presented live 19 June 2024 
Abstract
The Off-plane Grating Rocket Experiment pathfinder (OGRE-P) payload is a sub-orbital sounding rocket payload designed to obtain the highest resolution soft X-ray spectrum of Capella to date. OGRE was originally designed with a monocrystalline silicon X-ray optic developed by the Next Generation X-ray Optics Group (NGXO) at Goddard Space Flight Center (GSFC). This version of OGRE will be launched in the ultimate OGRE mission, OGRE-U. OGRE-P will use the Joint European X-ray Telescope (JET-X) in place of the GSFC optic in order to achieve an earlier launch date and test other components prior to the ultimate launch. JET-X has an angular resolution of 15 arcsec, which will produce an X-ray spectrum a factor of 3 broader than the GSFC optic. An updated error budget will be presented to reflect the alignment requirements for this lower spectral resolution optic, and the expected achievable resolution will be calculated. A plan for achieving alignment within these new tolerance requirements will be explained.
