U.S. Naval Research Laboratory scientists launched the second Strontium Iodide Radiation Instrument (SIRI-2) instrument in December 2021 onboard Space Test Program (STP) Sat-6. SIRI-2, a gamma-ray spectrometer, will demonstrate the performance of europium-doped strontium iodide gamma ray detection technology with sufficient active area for Department of Defense (DoD) operational needs.
The first SIRI mission was launched Dec.
Space weather will delay your trains

Fluctuations in space weather are disrupting train signals and causing significant delays. A project investigating the effect of solar storms on railway signals will be presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a Ph.D. student at Lancaster University.
The sun's tendency to affect technology on Earth, as well as in space, is known as space weather. In railways, electric currents caused to flow in the Earth by solar activity can interfere with the normal operation of signals, turning green signals to red even when there is no train nearby.
Patterson says: "Most of us have at one point heard the dreaded words: 'your train is delayed due to a signaling failure,' and while we usually connect these faults to rain, snow and leaves on the line, you may not have considered that the sun can also cause railway signals to malfunction.

ESA’s new Vega-C rocket has completed its inaugural flight, placing main payload LARES-2 – a scientific mission of the Italian Space Agency ASI – into its planned orbit. Six research CubeSats from France, Italy and Slovenia flew as secondary payloads. The launch caps a multi-year effort by ESA, prime contractor Avio and industrial partners in 13 ESA member states to build on the heritage of its predecessor, Vega.
