The Helios Prototype is an ultra-lightweight flying wing aircraft with a wingspan of 247 feet (75 m), longer than the wingspans of the U.S. Air Force C-5 military transport (222 feet (68 m) or the Boeing 747 (195 or 224 feet (59 or 68 m), depending on the model), the two largest operational aircraft built in the United States.
Personnel-based system evaluation aid (PER-SEVAL), which was used to assess crew performance in terms of time and accuracy; System performance and RAM criteria estimation aid (SPARC), which helped Army combat developers identify comprehensive and unambiguous system performance requirements needed to accomplish various missions
General Mission Analysis Tool (GMAT) is open-source space mission analysis software developed by NASA and private industry. [2]It has been used for several missions, including LCROSS, the Lunar Reconnaissance Orbiter, OSIRIS-REx, the Magnetospheric Multiscale Mission, and the Transiting Exoplanet Survey Satellite (TESS) mission.
FreeFlyer has been used to support many spacecraft missions, for mission planning analysis, operational analysis, or both. Specific mission examples include the International Space Station (ISS), [7] the JSpOC Mission System, [8] the Earth Observing System, [9] [10] Solar Dynamics Observatory (SDO), [11] and Magnetospheric Multiscale Mission (MMS).
The ESA/ESO/NASA FITS (Flexible Image Transport System) Liberator is a free software program for processing and editing astronomical data in the FITS format to reproduce images of the universe. Version 3 [ 1 ] and later are standalone programs; earlier versions were plugins for Adobe Photoshop .
In 1995, John C. Mankins, NASA, wrote a paper that discussed NASA's use of TRL, extended the scale, and proposed expanded descriptions for each TRL. [1] In 1999, the United States General Accounting Office produced an influential report [ 19 ] that examined the differences in technology transition between the DOD and private industry.
Composite gear transmission housing for aerospace is in development stage under the Advanced Rotorcraft Transmission program. [7] ART program is a joint Army/NASA program to develop and demonstrate lightweight, quiet, durable drivetrain systems for next generation rotorcraft.
His solution was a calculator that dispensed with many of the corrections and timing issues seen in devices like the Vickers Predictor which were intended for high-altitude fire. Instead, it made a relatively simple calculation of the impact point based on relative motion as provided by the operator.
