_otd-in-space-april-11-39project-ozma39-begins-search-for-alien-life.webp "On April 11, 1960, astronomers began the first scientific experiment that would search for extraterrestrial life.<br/><br/>Known as Project Ozma, this experiment looked for interstellar radio transmissions coming from other star systems. This was the first time that radio astronomy was used to look for aliens. The effort was led by an astronomer named Frank Drake at Cornell University. He used an 85-foot telescope at the National Radio Astronomy Observatory in Green Bank, West Virginia to check out two nearby stars called Tau Ceti and Epsilon Eridani. He first pointed the telescope at Tau Ceti, but he didn't detect any signals. When he pointed the telescope at Epsilon Eridani, he did see a signal, but it turned out to be a false alarm. He later found out that the signal was created by military radar equipment and was definitely not aliens.")

_moon-gravity-lab-in-the-sky-fly-with-lunar-scientists-in-this-exclusive-mini-doc.webp "European scientists are turning an aircraft into a laboratory that simulates lunar gravity to prepare astronauts and technology for future moon landings as part of the NASA-led Artemis missions. <br/><br/>The moon is a strange little world. Only about 1.2% the mass of Earth, our planet's companion exerts a much weaker gravitational force on objects on its surface than the parent planet. As a result, an astronaut on the moon's surface feels as if he or she only weighs one sixth of their earthly weight. The same goes for all equipment the astronauts would use. It may sound like no big deal but this feeble gravitational pull creates all sorts of unforeseen problems that are difficult to prepare for in research labs on Earth. There is, however, one way to experience lunar gravity while still in the confines of Earth and explore these challenges before going to the moon: in a parabolic flight.<br/><br/>Credit: Space.com | footage courtesy: European Space Agency/Novespace/NASA<br/>A Future Studios Production")
