The James Webb Space Telescope’s name honours NASA's second administrator, James E. Webb, who headed the agency from February 1961 to October 1968, and directed the Apollo programme.

The James Webb Space Telescope (Webb) follows in the footsteps of the Hubble Space Telescope as the next great space science observatory, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. Webb will push the frontiers of knowledge of our own Solar System, of the formation of stars and planets, including exoplanets, and of galaxy assembly and evolution, in ways never before possible.

Reflectix® products are thoroughly tested at either nationally approved, independent laboratories or leading universities. Tests are performed to current American Society of Testing and Materials (ASTM) standards when a standard exists.

Webb will observe the Universe in the near-infrared and mid-infrared — at wavelengths longer than visible light with a suite of state-of-the-art astronomical instruments.

For the Do-It-Yourselfer, Reflectix® has a product that enhances the performance of a Snow Melt System installed in a Concrete Slab; our specially designed Concrete Slab Insulation product. The addition of this product into a Snow Melt Concrete project will result in a higher level of energy operating efficiency. The bonus characteristic to this product is how easy it is to handle and install.

The telescope will launch on an Ariane 5 rocket from Europe's Spaceport in French Guiana. It will embark on a month-long journey to its final orbit about one and a half million kilometres from Earth, at the Lagrange point 2. In the first three weeks after launch, Webb will unfold its sunshield, which is the size of a tennis court, and then deploy its 6.5-metre primary mirror that will detect the faint light of distant stars and galaxies with a sensitivity a hundred times greater than that of Hubble.
