Signal Analyzer

The MS2840A signal analyzer from Anritsu (Richardson, TX) features frequency coverage of 9 kHz to 44.5 GHz and close-in SSB phase noise performance. Frequency coverage can be extended to the millimeter wave (mmWave) range. The analyzer can conduct wideband and narrowband measurements on next-generation 4G/5G designs, micro wave and mmWave wireless backhaul, 79 GHz band automobile radar, satellite communications, and VHF/UHF Private Mobile Radio (PMR). The unit’s oscillator achieves phase noise performance of –123 dBc/Hz at 1 GHz measurement frequency, and 10 kHz offset frequency. For Free Info Visit http://info.hotims.com/61064-405

Human Spaceflight Takes a Giant Leap

Inside the Operations and Checkout Building high bay at Kennedy Space Center, technicians install a back shell tile panel onto the Orion crew module, and check the fit next to the middle back shell tile panel in preparation for Exploration Flight Test-1. (NASA/Dimitri Gerondidakis) NASA is developing the capabilities needed to send humans to an asteroid by 2025, and to Mars in the 2030s. While robotic explorers have studied Mars for more than 40 years, NASA’s path for the human exploration of Mars begins in low Earth orbit aboard the International Space Station (ISS). Astronauts on the ISS are proving many of the technologies and communications systems needed for human missions to deep space, including Mars. The ISS also advances understanding of how the body changes in space, and how to protect astronaut health.

Suiting Up for the Future

NASA is developing the next generation of suit technologies that will enable deep-space exploration by incorporating advancements such as regenerable carbon dioxide removal systems and water evaporation systems that more efficiently provide crewmembers with core necessities such as breathing air and temperature regulation. Mobility and fit of a pressurized suit are extremely important in keeping astronauts productive, so NASA is focusing on spacesuit designs to help crews work more efficiently and safely during spacewalks.

Modified Monitor Provides Glasses-Free 3D for Pilots and Gamers

NASA technology enables monitors that switch between 2D and 3D imaging. When flying the increasingly crowded skies, pilots need to have an arsenal of information: altitude, airspeed, fuel level, distance to their destination, and the location of other planes in the sky. All of this information is presented in a series of two-dimensional instruments, panels, and readouts, meaning the pilot has to mentally assemble the information and translate that into the 3D world to better understand the relationship among air, ground, and traffic. NASA has long been interested in making it as easy as possible for pilots and astronauts to have the best information available to ensure safe flights, knowing that humans are imperfect creatures.

Precise Measurements on Earth Enable Further Exploration in Space

Measurement is the first step to success. If you can’t measure something accurately, it can’t be understood or improved. That is especially true for the spacecraft rockets and engines designed to operate under extreme temperatures and pressures at liftoff, or space stations the size of a six-bedroom house that must support people living and working in space for years.

Next-Generation Infrared Technologies Solve High-Speed Automotive Testing Challenges

Higher-speed IR cameras can improve design phase testing. Product research and development on internal combustion engines, brake rotors, tires, and high-speed airbags are just a few of the areas that truly benefit from high-speed, high-sensitivity thermal characterization testing. Unfortunately, traditional forms of contact temperature measurement such as thermocouples are not practical to mount on moving objects, and non-contact forms of temperature measurement such as spot guns — and even current infrared (IR) cameras — are simply not fast enough to stop motion on these high-speed targets in order to take accurate temperature measurements.

Creating Advanced Dosimeters Requires Thorough Inspection of Small Components

The McMaster University students will launch the small satellite into low Earth orbit to study the effects of ionizing radiation on the human body. Recent advancements in space technology have resulted in space exploration becoming a rapidly growing field, and the desire for human space exploration is drastically increasing. Previous manned missions include flights to low Earth orbit (LEO), such as to the International Space Station (ISS); however, upcoming flights are planned to go beyond LEO, such as to asteroids and eventually Mars. A major consideration in such missions is that the space environment is significantly different from that of Earth, especially with respect to the radiation environment. This drastic difference results in concerns regarding radiation dose.
