The Earth And The Moon Shaped Analyzed By NASA

 

The interior of the moon is covered into a hard, outer crust, a rigid outer mantle, a semi-rigid inner mantle, and a core. The interior of the moon is cooler than the center of the Earth. While the moon is so tiny it loses its heat rapidly into space. Since the Earth and the moon shaped, the moon has cooled down much extra than the Earth.

The moon's surface is so dry, dusty and rocky place. The rocky crust is about 37 miles (60 km) broad on the side of the moon that faces Earth and about 62 miles (100 km) thick on the reverse side of the Moon. Radioactive dating of moon rocks from NASA's Apollo task dates the construction of the moon from about 4.3 billion years ago (about 60 million years after the construction of the Earth). Moon rocks that have been analyzed by NASA are parallel to Earth rocks, but are richer in the basics aluminum and titanium.

NASA Develops Super-Black Material That Absorbs Light Across Multiple Wavelength Bands

NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it a development that promises to open new frontiers in space technology.The team of engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., reported their findings recently at the SPIE Optics and Photonics conference, the largest interdisciplinary technical meeting in this discipline. The team has since reconfirmed the material's absorption capabilities in additional testing, said John Hagopian, who is leading the effort involving 10 Goddard technologists.

"The reflectance tests showed that our team had extended by 50 times the range of the material’s absorption capabilities. Though other researchers are reporting near-perfect absorption levels mainly in the ultraviolet and visible, our material is darn near perfect across multiple wavelength bands, from the ultraviolet to the far infrared," Hagopian said. "No one else has achieved this milestone yet."

The nanotech-based coating is a thin layer of multi-walled carbon nanotubes, tiny hollow tubes made of pure carbon about 10,000 times thinner than a strand of human hair. They are positioned vertically on various substrate materials much like a shag rug. The team has grown the nanotubes on silicon, silicon nitride, titanium, and stainless steel, materials commonly used in space-based scientific instruments.
