As it descended, Eagle encountered issues not anticipated in simulations. Multiple alarms went off due to too many tasks being attempted at once by its computer system. Armstrong and Aldrin spent 21 hours 38 minutes on the moon’s surface before returning to Collins in Columbia’s command module, using seismometers and laser reflectors to measure distances…
Encourage children to act out the various stages in a frog’s life cycle. They can draw their own diagram, or use this printable life cycle worksheet with pictures as reference for cutting out. Students can click and drag vocabulary words for kids’ frog life cycle vocabulary into the appropriate boxes, facilitating language acquisition especially among…
Players take turns asking the person next to them for a specific type of insect card. If a player possesses it, they give it over. Play concludes when an entire Draw pile has been depleted. Students will gain insight into insects as they change shape as they grow older, as well as understanding metamorphosis’ importance…
On Tuesday morning, astronomy enthusiasts from Asia, Australia and North America witnessed the Moon slowly become darker until its full eclipse became visible; otherwise known as a blood moon. This event would mark the last total lunar eclipse until 2025. An appearance of a blood moon occurs when direct sunlight is blocked and its light…
People often mistakenly believe that the sky’s hue comes from ocean waves; however, this is incorrect: its hue results from how atmospheric molecules scatter light and reflect it back onto Earth’s surface. Light passing through the atmosphere tends to scatter more readily in blue and violet wavelengths due to their frequencies being closer to those…
In 1969, planetary science was still relatively young. One of its most famous moments occurred on July 20, when Neil Armstrong and Buzz Aldrin left Columbia and entered their lunar module, Eagle. Armstrong used Eagle’s reaction control system to guide their landing site in the Sea of Tranquility. Mission Overview Nasa embarked on its most…
Spacecraft dynamics is an engineering discipline encompassing rigid-body and multi-body analyses as well as orbital mechanics and attitude control. The Spacecraft Dynamics block supports expansion of all input ports except Moon libration angles and Spin axis right ascension at J2000 (when Central body is Custom). This enables the model to accurately simulate gravity gradient effects…
Take your boating experience to the next level with Mercury outboard engines. These robust yet reliable engines are designed for maximum maneuverability across a range of vessel sizes. Mercury Marine has been crafting world-class outboard engines since 1939 to give boaters reliable power for any waterborne activity. Each Mercury engine is engineered to be fuel…
Point Nemo serves as a global spacecraft graveyard since 1971, when nations began leaving old satellites and spacecraft there for disposal. To reduce space junk that could endanger working satellites or humans if it falls back down, they are purposefully put into graveyard orbit or sent directly over an ocean surface. How They Are Disposed…
