Two successful NASA Langley Research Center led sub-orbital flight demonstrations of HIAD technology have occurred; Inflatable Reentry Vehicle Experiment 2 (IRVE-2) [7] and IRVE-3 [8] were flown in 2009 and 2012 respectively. LOFTID is the first orbital flight of a HIAD and the largest blunt bunt aeroshell entry to date.
The higher conversion efficiency of the Stirling cycle compared with that of radioisotope thermoelectric generators (RTGs) used in previous missions (Viking, Pioneer, Voyager, Galileo, Ulysses, Cassini, New Horizons, Mars Science Laboratory, and Mars 2020) would have offered an advantage of a fourfold reduction in PuO 2 fuel, at half the mass of an RTG.
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
The circularly-polarized antenna operated at the X-band NASA Deep Space Network (NASA DSN) frequencies of 7.2 and 8.4 GHz, and had a gain of 29.8 dBi on downlink and 23.6 dBi on uplink. The fabricated antenna in a flat and compact shape exceeded the given requirements and was tested through environments resulting in a TRL -6 design.

Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
This week, NASA revealed that the International Space Station’s Environmental Control and Life Support System (ECLSS) is recycling 98 percent of all water astronauts bring aboard the station.
The Voyager spacecraft were built and continue to be operated by NASA's Jet Propulsion Laboratory, in Pasadena, Calif. On December 4, 2012, eleven billion miles from Earth, NASA's Voyager 1 spacecraft has entered a "magnetic highway" that connects the Solar System to interstellar space. The "magnetic highway" is a place in the far reaches of ...
