Modern CMOS Cameras as Replacements for CCD Cameras

Many users of CCD sensors are asking about the advantages of the latest CMOS sensors, particularly if they have been using CCD-based cameras. The two sensor technologies, a comparison of the new CMOS sensors and existing CCD sensors, and tips for when it makes sense to select a new camera with CMOS sensors are provided in this article, as well as what to expect after integration.

Underwater Adhesives Retrofit Pipelines with Advanced Sensors

NASA-developed sensors and adhesion methods equip pipelines and tension legs that hold offshore platforms upright for safety monitoring. By the time the gas you fill your car with hits the engine, it’s been through quite a journey. An oil platform in the Gulf of Mexico, for example, might need to be built over water with a depth of 10,000 feet. Long pipelines under high pressures face a multitude of dangers. Some are structural, such as natural vibrations generated by ocean currents and waves that bend the pipes back and forth — a phenomenon known as vortex-induced vibration, which is similar to the sway of a car antenna wire when driving on the highway. Other risks lie inside the pipe, where the right combination of pressure and temperature causes the hydrates in the oil to precipitate, forming a dirty, snowball-like mass that quickly grows.

Editor's Choice: October 2015

A habitat was developed that allows water recycling, air treatment, thermal control, and solids treatment and recycling to be performed in the walls of a radiation-shielding water wall. This game-changing method for mass reuse provides radiation protection, building materials, and structural elements for a habitat. The method can also be used in wastewater treatment plants, and removes the air, water, and waste treatment hardware from the usable habitat. Find out more HERE.

Vegetation Essential for Limiting City Warming Effects

The urban heat island effect of a city has long been observed to raise the temperature of big cities by 1.8 to 5.4°F, a rise that is due to the presence of asphalt, concrete, buildings, and other impervious surfaces disrupting the natural cooling effect provided by vegetation. According to a new NASA study that makes the first assessment of urbanization impacts for the entire continental United States, the presence of vegetation is an essential factor in limiting urban heating.

Hollywood Gets Real with NASA

“The Martian,” a movie that will be released this month, merges fiction and facts about Mars, building upon the work NASA and others have done exploring Mars, and moving it into the 2030s, when NASA astronauts are regularly traveling to Mars and living on the surface. NASA is already developing many of the technologies that appear in the film.

Imitative Robotic Control: The Puppet Master

Automated systems can have a hard time completing complex tasks in a timely manner. When controlling a robot outside autonomous mode, a good control device needs to give the user full control of the system while enabling the mission to be completed in a quick, accurate, and efficient manner.

Voyage to “New Horizons”

NASA’s New Horizons spacecraft traveled more than three billion miles over nine-and-ahalf years, reaching the Pluto system in July. The mission will help us understand worlds at the edge of our solar system by making the first reconnaissance of Pluto.
