Scientific paper

We have assembled and launched the Diffuse Interstellar Cloud Experiment (DICE), an instrument capable of recording high resolution (λ/δλ = 30,000) spectra in the Far Ultraviolet (FUV). Absorption measurements toward nearby bright stars can provide new insight into the processes governing warm-hot gas in the Local Interstellar Medium. It flew on May 21st, 2010. An anomaly in the Black Brant motor subjected the payload to abnormally high vibration. As a result, the optics were misaligned and no spectral data fell on the detector. Here we present the details of mechanical and electrical integration with NASA launch systems, as well as optical alignment of the telescope and spectrograph. In addition, we summarize the flight results.
