In 24 Stunden dreht sich unser Planet einmal um seine Achse und wir erleben einen Tag und eine Nacht. Doch wie ist das auf dem Mond? Die Umdrehung des Mondes um die eigene Achse ist nicht wie die der Erde. Etwa 14 Tage lang trifft viel Sonnenlicht auf den Mond, gefolgt von 14 sehr dunklen Tagen.<\/p>\n<\/div>\n<p>This is a problem for future human Moon explorers as they will need sunlight to shine on solar panels that in turn produce much needed electricity. At least, that has always been the plan\u2026 until now! ESA researchers are investigating a new way of using the layer of moondust that covers the Moon as a kind of battery. During the Moon\u2019s daytime the moondust absorbs and stores energy from sunlight. Could the energy be released at night and used to produce electricity?<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"Jorge Ma\u00f1es Rubio.
