Pulsed Solid-State Laser

The TruPulse laser from TRUMPF (Farmington, CT) is a pulsed solid-state laser that allows the average power to be briefly exceeded and increases the pulse frequency. The product range is based on a modular supply structure, and the average power ranges from 20 to 150 watts at a maximum pulse power of up to 10 kilowatts. Within this range, beam qualities of 4 to 25 mm•mrad are possible.

Diving Equipment Helps Expedition Team Uncover Microbial Adaptation to Harsh Environments

CODE Rebreathers and SSV Lifejackets Aqua Lung Vista, CA 760- 597-5000 The High Lakes Project (HLP) is funded by a grant from the NASA Astrobiology Institute to the SETI/NAI team. The HLP is an endeavor involving a team of expert scientists, mountainclimbers, and divers that will explore the ecosystems of three high-altitude-summit lakes in Bolivia and Chile. The physical and environmental conditions around and in these lakes — characterized by a thin atmosphere, temperature swings, and intense ultraviolet radiation — are uniquely analogous to ancient Martian lakes about 2.7 billion years ago. Learning about how microbial organisms adapt to such harsh environments is a critical step in preparing for life on Mars. The HLP also aims to understand how rapid climate change affects life and habitats, which is relevant to Martian exploration and to Earth’s current evolution.

Power Complex Protects NASA Test Equipment

Centralized Uninterruptible Power Supply (UPS) Lee Technologies Fairfax, VA 703-968-0300 NASA’s Stennis Space Center in Bay St. Louis, MS, is NASA’s primary site for rocket propulsion testing. It is also home to the Applied Research and Technology Project Office (ARTPO), which supplies project management to support NASA’s science and technology goals. Recently, Stennis awarded Lee Technologies a contract to construct a centralized uninterruptible power supply (UPS) and emergency generator. Under the terms of the contract, Lee Technologies will partner with Z Corporation in Burlington, MA, to construct the power complex at Stennis.

Battery Power Source Options for Mission-Critical Applications

Selecting power source technology for mission critical devices is crucial to ensure success. Whether it is a monitor at the bottom of the ocean, a drill system at 30,000 feet into the Earth’s crust, or hand warmers on an astronaut in Earth orbit, the cost of failure in these situations far outweighs the cost of a battery. Equipment used in these and other mission- critical situations must perform under environmental conditions that would destroy most commercially available components and energy sources. Every element must be capable of operating in environments where extremes in temperature, pressure, shock, vibration, and corrosive exposure are the norm. Selecting batteries for these vital activities must include consideration for the high level of reliability and performance required to ensure these significant and often costly programs stay on target.

Karen Whitley, Expandable Structures for Exploration Task Lead

NASA Langley Research Center, Hampton, VA Karen WhitleyNASA plans to return to the Moon by 2020. For a sustained lunar presence, however, astronauts need habitats that can support them and their experments. To this end, researchers at NASA Langley, working with NASA contractor ILC Dover (Frederica, DE), are developing the “planetary surface habitat and airlock unit,” a prototype inflatable structure that could be deployed on the lunar surface. Karen Whitley is the project lead.
