Mini Solar Observatory Can Be Used on Manned Spacecraft

Southwest Research Institute (SwRI) developed a miniature portable solar observatory for use onboard a commercial, manned, suborbital spacecraft. The SwRI Solar Instrument Pointing Platform (SSIPP) uses a classic, two-stage pointing system similar to larger spacecraft, but in this case, the first stage is a pilot who initially steers the instrument toward the Sun. SSIPP does the rest, locking onto the Sun to allow observations. The first SSIPP spaceflight will search for “solar ultrasound,” a phenomenon first observed in the early 2000s by the Transitional Region and Coronal Explorer (TRACE) spacecraft. The ultrasound is sound waves with a 10-second period, some 18 octaves deeper than ultrasound on Earth, and forms visible ripples in the Sun’s surface layers. The waves are difficult to detect without space instrumentation because the tiny, rapid fluctuations cannot be separated from the confounding influence of Earth’s turbulent atmosphere. Although at first SSIPP will be operated from inside the cockpit, a full system eventually will be mounted outside the host vehicle to enable UV and X-ray observations that are inaccessible from the ground.

New Serenity Payload Detects Hostile Fire

Two government-developed sensors are working together to increase the security of deployed soldiers. The Firefly and Serenity sensors employ government developed algorithms, software, and hardware to locate hostile fire around a base. The technology, a joint effort between the Army Aviation Research, Development and Engineering Center, or AMRDEC, and the Army Research Lab, referred to as ARL, has been under development for more than a decade.

Magnetic Thermometer for High-Resolution 10-mK Scale Thermometry

Device features improved sensitivity. Goddard Space Flight Center, Greenbelt, Maryland A thin-film magnetic thermometer with integrated, superconducting quantum interference device (SQUID) readout has been designed for fast, precision temperature measurements in the 10-mK range. The compact magnetic thermometer consists of a miniature DC SQUID susceptometer with a dilute paramagnetic alloy deposited in one of the two series-configured, gradiometric SQUID pickup loops that form the SQUID inductance. Directly sensing the magnetic signal with the SQUID eliminates coupling losses that occur by transformer-coupling the signal to a remotely located SQUID, usually operating at a higher temperature, and consequently, with a higher noise floor.
