The amino acid ionic liquids have great potential for CO2 absorption in manned confined spaces, such as spacecraft, submarines and other equipment.

In various kinds of switched-mode power converters, conducted noise due to switching operation frequently causes interference with other electronic equipment. This paper focuses on the common-mode conducted noise generated in switched-mode power converters and presents three examples of noise reduction techniques. First, the common-mode conducted noise is reduced in a common-source type active-...

high-precision three-axis attitude control scheme is vitally important to deal with the overactuated spacecraft, as long as the overall performance through rapid response can be in general acquired. due to the fact that the rigid-flexible spacecraft is somehow applicable, in so many academic and real environments, there is a consensus among experts of this field that the new insights in develop...

• Attitude control – usually autonomous in satellite missions running in a dedicated processor. Its development and testing requires particular conditions. Its development and testing requires particular conditions. For instance, the gravity and air resistance are variables that overcome the effects which disturb the spacecraft attitude on orbit. For this reason, the use of a set of software sy...

Spacecraft hardware and assembly cleanroom surfaces (233 m(2) in total) were sampled, total genomic DNA was extracted, hypervariable regions of the 16S rRNA gene (bacteria and archaea) and ribosomal internal transcribed spacer (ITS) region (fungi) were subjected to 454 tag-encoded pyrosequencing PCR amplification, and 203,852 resulting high-quality sequences were analyzed. Bioinformatic analyse...

As part of its research program in spacecraft operations, Stanford University’s Space Systems Development Laboratory (SSDL) is developing a ground station control system to support advanced command and telemetry operations. Known as Mercury, this control system provides direct human console control, remote human tele-operation, and script/program based autonomous control. Each of these modes su...

Satellite communications, navigation systems and electrical transmission equipment all rely heavily on Wireless Technologies. Solar storms are predicted in the near future and this could have “devastating effects” on human technology as they can release particles that subsequently disable or permanently destroy computer circuits. Solar storms can vary in size and as a result can have different ...
