Rutgers Ultraviolet Detector Lab
involvement with NASA Missions

STIS -- Space Telescope Imaging Spectrograph, a second generation instrument for the Hubble Space Telescope. It was launched and installed into HST in February 1997. C. Joseph is, an instrument team Co-Investigator and the detector scientist for the ultraviolet MAMA Detectors.
The Interstellar Medium Absorption Profile Spectrograph (IMAPS) initially was a Sounding Rocket (launched: 1985 & 1987). IMAPS is a far-ultraviolet (wavelengths 900-1150 Angstroms) echelle spectrograph with velocity resolution of 1.2 and 2.4 km/s, higher even than the spectrographs on HST. Relevant Detector: the EBCCD.
ORFEUS/IMAPS -- Orbiting Retrievable Far and Extreme Ultraviolet Spectrometers was a joint NASA/DARA (USA/German) orbital mission which IMAPS flew piggy back in 1993 and again in 1996. The Columbia shuttle carried ORFEUS/IMAPS into space, the astronauts deployed the spacecraft, which became a free-flying satellite for 7 to 10 days before being recaptured and brought back to earth. Relevant Detector: the EBCCD.
NPOESS/SESS -- National Polar­orbiting Operational Environmental Satellite System is a governmental multi-agency program to monitor the impact of our sun on the earth's atmosphere. The information is necessary to protect and react to conditions that may adversely impact the power grid and telecommunications. Rutgers is supporting Ball Aerospace with far-ultraviolet detectors.
OWL Orbiting Wide-angle Light-collectors is an envisaged NASA Great Observatory to study ultra-high energy cosmic rays. The mission will consist of two 7-m aperture telescopes looking down at the earth's atmosphere. When a ultra-high energy CR hits the atmosphere it creates a near-ultraviolet shower. The OWL telescopes will be able to measure hundreds of events per year, determining the direction of origin and energy. The detector challenge is to develop a near-UV detector that is more than 100x larger than any previous device and to be able to capture frames very rapidly over the several millisecond event.
SUVO --- Space Ultraviolet/Visible Observatory is an envisaged NASA Great Observatory to replace the Hubble Space Telescope. SUVO will have an aperture between 4 m and 8 m, compared to HST's 2.4 m. The observatory, as its name implies, will cover the visible and ultraviolet wavelengths. Currently, ultraviolet detectors have a quantum efficiency (sensitivity) of only 10-20%. To make take full advantage of SUVO, UV detector with visible-blind quantum efficiencies of 80% or more will be required. AlGaN solid-state are the only devices under development that meet this criteria.
HAWK -- Hierarchical Assembly through Wide-field Kinematics is a proposed Long-Duration Balloon Mission. HAWK will have a floation altitude of 35 km (just under 22 miles) and will carry a 1.8 meter telescope, providing spatial resolution comparable to the Hubble Space Telescope, but one that has 100x the efficiency to map the 2-D velocities. HAWK will empirically determine how galaxies formed and evolved without relying on models.
Kronos --- Kronos (for time keeper) is a proposed Midex Mission for monitoring long-term variability over a broad range of wavelengths. Projects include reverberation maps of quasars as material fall into black holes and stellar flares, among other topics.
