DC-8 Airborne Science Laboratory

DC-8 taking off

NCAR-NASA Deep Convective Clouds and Chemistry thunderstorm stud NASA's Airborne Science Program and the National Suborbital Education and Research Center (NSERC) at the University of North Dakota jointly manage science operations of NASA's DC-8 Airborne Science Laboratory aircraft. Based at NASA Armstrong's Building 703 in Palmdale, CA, the unique flying laboratory collects data for experiments in support of scientific projects serving the world's scientific community, including investigators from NASA and other federal, state, academic, and foreign institutions. The DC-8 flies three primary missions - sensor development, satellite sensor verification, and basic research studies of the Earth's surface and atmosphere.

Data gathered by the DC-8 at flight altitude and by remote sensing have been used for scientific studies in archeology, ecology, geography, hydrology, meteorology, oceanography, volcanology, atmospheric chemistry, soil science, and biology.

Those interested in the DC-8's capability to accommodate instruments are encouraged to consult the 'DC-8 Experimenter's Handbook' (see below). The DC-8 is one of several aircraft based at the NASA Armstrong's Building 703 that support NASA's Airborne Science Program .                  

DC-8 Science-Specific Capabilities:

NASA's DC-8 Airborne Science Laboratory, a -72 version of the four-engine first-generation jetliner, was acquired in 1985 and highly modified to support its airborne science mission. The aircraft has a range of 5,400 nautical miles (6,200 statute miles) and can fly at mission altitudes from 1,000 to 42,000 feet for up to 12 hours, although most science missions average 6 to 10 hours. The DC-8 can carry 30,000 pounds of scientific instruments and equipment.

The aircraft has many modifications specifically oriented to support scientific research. These include zenith and nadir instrument ports; modified window ports for instrument and probe mounting; external antenna mounts; wing pylon instrument mounts; optical windows of various materials; a dropsonde delivery tube; air and aerosol sampling probes; standard 19-inch equipment racks (up to 20 racks and 25 instruments typically accommodated); a laser chiller unit; both 400 Hz and 60 Hz power available to experimenter stations; and seating for up to 45 experimenters and flight crew.

The DC-8 flying laboratory also incorporates a suite of operational aircraft and data systems that can be tailored to specific missions or science instruments. These include weather radar; global positioning and inertial navigational systems; a radar altimeter; sensors for recording total air temperature, ambient pressure, and relative humidity; a time code generator (NTP and IRIG-B), video, and digital recording systems; data acquisition, distribution, and recording systems; an Ethernet LAN with servers; and Web-based displays.
