Webb: A new view of the Universe


The world’s next generation cosmic observatory, the James Webb Space Telescope, is due for launch on an Ariane 5 from Europe’s Spaceport in French Guiana in late December.

Developed and constructed over more than 30 years, Webb is a remarkable feat of engineering and technology – with the largest astronomical mirror ever flown in space, sophisticated new scientific instruments, and a sunshield the size of a tennis court.

Webb is an international partnership between @NASA, ESA and the @Canadian Space Agency and will reveal the Universe in a whole new light. Optimised for infrared wavelengths, its detectors will be able to look back to shortly after the very dawn of time, revealing the formation of the first galaxies, as well as study stars and planets in our own Milky Way.

  1. There are many flaws in this design. There are no adequate solar panels (2kw) and no batteries to operate all those motors, actuadores, sensors, transreceivers and energy needed to keep the Hydrazine and Dinitrogen tetroxide at its operating temperature. The quantity and the location of the boosters will not provide 3-axis maneuvering required for attitude and orbital positioning. The telescopic / hydraulic rods used to deploy the sun shields are the worst design since they are vulnerable to vibration, stress and more importantly to extreme temperature variations. It seems that this satellite, just like all other satellites, will be mounted on a platform hanging from a high altitude balloon that supplies the power needed for its operation. As you saw in the videos, the builders are able to lift the 6+ tons satellite by holding it to its one side, which means this is not a design for weightless structure, but is a design to hold the satellite by its mounting bracket.
