Finding NEEMO

A group of astronauts, engineers, and scientists ventured to the bottom of the Atlantic Ocean this summer to prepare for future deep space missions and the journey to Mars. Isolating crew members at the bottom of the ocean simulates life and work for astronauts in microgravity environments like the International Space Station (ISS), or in spacecraft that will travel to asteroids and planets in the future.

Next Mars Rover Heads Toward 2020 Launch

NASA is ready to proceed with final design and construction of its next Mars rover, currently targeted to launch in the summer of 2020 and arrive on the Red Planet in February 2021. The Mars 2020 rover will collect samples of soil and rock, and cache them on the surface for potential return to Earth by a future mission.

AGM Thumbtack™ Valves for Small Enclosures: Smaller and Drier

Sensitive equipment such as optics and electronics can be damaged by humidity and condensation. Placing moisture-sensitive equipment inside a sealed enclosure reduces the risk of damage, but temperature and pressure variations can be problematic for a sealed enclosure if it does not have a pressure-relief mechanism.

Tailor-made Computing Solutions Require Diverse I/O Functions

More than ever, users from industry and transportation expect the full system solution, but no longer want to have to worry about the cumbersome configuration and integration of individual hardware components and adapting the software. There is a very simple reason for this: the system supplier of their choice reduces the time to market and is also responsible for the entire system at the same time.

Smartphone Video Guidance Sensor

The need arose to apply the state determination algorithms developed for the Advanced Video Guidance Sensor autonomous rendezvous and docking (AR&D) sensor onto a commercial off-the-shelf (COTS), smartphone-based platform to create a lower-mass, lower-cost sensor for small satellite and CubeSat applications. Prior techniques used for state determination suffer one or more of the following problems: large mass, large volume, high cost, or computationally intensive calculations.

Terminal Airspace Configuration Scheduler (TACS)

In the current National Airspace System (NAS), there are many airports that are capacity-limited during the busiest parts of the day, and air traffic is expected to increase substantially in the future. NASA and the FAA are looking toward technologies that improve the capacity and efficiency of the NAS. The Terminal Airspace Configuration Scheduler (TACS) algorithms were developed for use in current research simulations for systems analysis of the NAS. These algorithms also could be the basis for new airspace management tools for use in the actual NAS as a means of improving airport arrival capacity through more efficient management of the arrival traffic system.

Using a Power Grid as an Extremely Large Antenna for Geophysical Imaging

Geomagnetic storms drive geomagnetically induced currents (GICs) in high-voltage power transmission systems. GICs thus carry information about the near-space environment conditions. The U.S. high-voltage power transmission system was used as an extremely large antenna to extract unprecedented spatiotemporal space physical and geological information from distributed GIC observations.
