“This is an HP-41C pocket calculator, manufactured by Hewlett-Packard, that has flown on nine Space Shuttle missions in the 1980s. NASA purchased it from a local store in Houston, and installed special software on it for each mission. Mission critical computing was still done by the Shuttle on-board computers, but pocket” calculators found many other uses in space. This calculator could have performed critical re-entry calculations if the main computers failed. This HP-41C was used by Astronaut Sally Ride and several other astronauts on a total of nine Shuttle missions.” source https://airandspace.si.edu/collection-objects/calculator-hand-held-hp-41/nasm_A19890003000

2023 November 17 Nightlights in Qeqertaq * Image Credit & Copyright: Dennis Lehtonen Explanation: Light pollution is usually not a problem in Qeqertaq. In western Greenland the remote coastal village boasted a population of 114 in 2020. Lights still shine in its dark skies though. During planet Earth's recent intense geomagnetic storm, on November 6 these beautiful curtains of aurora borealis fell over the arctic realm. On the eve of the coming weeks of polar night at 70 degrees north latitude, the inspiring display of northern lights is reflected in the waters of Disko Bay. In this view from the isolated settlement a lone iceberg is illuminated by shore lights as it drifts across the icy sea.
