Characterising and Testing Deep UV LEDs for Use in Space Applications
TL;DR: In this paper, a test campaign was carried out to quantify the general properties of three types of commercially available UV LEDs and demonstrate their suitability for use in space, including spectral stability, pulsed performance, temperature dependence as well as thermal vacuum, radiation and vibration survivability.

TL;DR: In this article, the Weak Equivalence Principle (WEP) was tested to a precision of $10^{-15} by using two masses of different compositions (titanium and platinum alloys) on a quasi-circular trajectory around the Earth.

TL;DR: A ~6 arcmin2 region in the Bootes Deep Field is imaged using the 350 μm-optimized second-generation Submillimeter High Angular Resolution Camera (SHARC II), achieving a peak 1 σ sensitivity of ~5 mJy, and an integral source count of 0.84 sources arcmin-2 is derived, consistent with 350μm source count models that have an IR-luminous galaxy population evolving with redshift.
