The Technology of Curiosity

On April 14, 2004, NASA announced an opportunity for researchers to propose science investigations for the Mars Science Laboratory (MSL) mission. Eight months later, the agency announced selection of eight investigations. In addition, Spain and Russia would each provide an investigation through international agreements. The instruments for these ten investigations make up the science payload on the Curiosity rover.

An Ionic Twist on Hair Care

Nanomaterials developed by NASA play a big role in professional hairstyling tools.Disinfecting can be dirty work. Typical cleaning agents, like chlorine and alcohol, release fumes that don’t go away when applied in the contained environment of a spacecraft. So NASA scientists developed an alternative method to keep surfaces disinfected, using a material whose antimicrobial properties have long been known: nanosilver.

The GigE Vision® Interface Standard: Transforming Medical Imaging

Live, high-resolution imaging is increasingly being leveraged to enhance operating procedures. It can improve the precision of physicians and their instruments, and minimize the invasiveness of many procedures. Increasingly, one small component in a vision system — the interfacing technology — is providing answers to the most common of these challenges.

The Future Looks Dimmer

New LED Controller Technology Could Make Dimming Problems a Thing of the Past Originally fueled by environmental concerns and the steadily rising cost of electricity, the market for energy- efficient lighting has been dramatically accelerated by regulations that will restrict the sale of most incandescent bulbs in North America, Europe, and Asia.

Specifying Gaskets for Outdoor LED Lighting Fixtures

LED lighting technology has the potential to lower energy consumption and reduce maintenance costs on outdoor installations such as area lighting and parking lights, street lights and other “difficult to reach” outdoor locations. When operating in controlled temperatures and weatherproof environments, solid state LED lights are designed to operate for 5 to 10 years. Outdoor LED housings and lighting enclosures are constructed from powder coated aluminum to resist the effects of direct sun and weather for many years. However, if the full payback on the investment in outdoor LED lighting is to be realized, the gaskets required to protect the solid state electronics must function for the 5 to 10 year life of the product.

Researchers Study How to Avoid Charge Traps in Plastic Electronics

Plastic electronics hold the promise of cheap, mass-produced devices. But plastic semiconductors have an important flaw – the electronic current is influenced by “charge traps” in the material. These traps, which have a negative impact on plastic light-emitting diodes and solar cells, are poorly understood.
