Optomechanical design of a broadband cryogenic optical system for ground testing of the Ariel payload

ESA’s Ariel space telescope is due to launch in 2029 and aims to measure broadband (0.5 – 7.8 µm) spectra from ∼1000 known transiting exoplanets. For optimum stability the payload uses an all aluminium telescope with an extremely narrow (30 ′′) field of view. Prior to integration with the spacecraft, the Ariel payload...

Lunar Trailblazer Spacecraft Tracking and Mission Recovery Attempt: Characterization of Status and Behavior of a Non‐Cooperative Object in Cis‐Lunar Space

Unexpectedly following launch, the Lunar Trailblazer mission experienced software anomalies that led it to orient solar panels away from the sun and lose communication with Earth. This paper describes efforts to determine the spacecraft state and attempt recovery of the mission's science at the Moon. First, ground obse...
