Protoflight is a portmanteau of "prototype" and "flight hardware". As defined by NASA Technical Standard NASA-STD-7002A, [1] it refers to a strategy where no test-dedicated qualification article exists and all production (flight) hardware is intended for flight. An example of a program using protoflight methods is the Mars Orbiter Laser ...
The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
The Power of 10 Rules were created in 2006 by Gerard J. Holzmann of the NASA/JPL Laboratory for Reliable Software. [1] The rules are intended to eliminate certain C coding practices which make code difficult to review or statically analyze.
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.
The NASA X-57 Maxwell was an experimental aircraft developed by NASA, intended to demonstrate technology to reduce fuel use, emissions, and noise. [2] The first flight of the X-57 was scheduled to take place in 2023, but the program was cancelled due to problems with the propulsion system. [3] [4] [5]
Gemini 7 as seen from Gemini 6 during their rendezvous in Earth orbit in 1965 (NASA). Earth orbit rendezvous (EOR) is a method for conducting round trip human flights to the Moon, involving the use of space rendezvous to assemble, and possibly fuel, components of a translunar vehicle in low Earth orbit. [1]
Isogrid on the interior of the adapter connecting the Orion spacecraft to the Delta IV rocket for Exploration Flight Test 1. Isogrid is a type of partially hollowed-out structure formed usually from a single metal plate with integral triangular stiffening stringers.
Genesis was a Discovery-class mission of the NASA Jet Propulsion Laboratory (JPL) at the California Institute of Technology. The spacecraft was designed and built by Lockheed Martin Space Systems at a total mission cost of US$264 million. NASA launched the craft on a Delta II 7326 rocket on August 8, 2001, at 16:13:40 UTC from Cape Canaveral.
