Bluesky is a social network similar to Twitter but not owned by Elon Musk. Despite still being in its early stage of development, Bluesky boasts a substantial user base. Air particles in our atmosphere are smaller than the wavelengths of light, meaning they scatter blue light more readily than any other color – giving the…
President Kennedy issued an ambitious challenge for Americans to reach the moon by 1961 and place two men on its surface. NASA achieved this goal in July 1969 when Neil Armstrong and Edwin “Buzz” Aldrin became the first people ever to step foot onto its surface while Michael Collins orbited around it with Columbia Command…
Oceans help maintain our global climate by storing heat and moving water across its expanse, and they serve as home for numerous ecosystems. Ocean animals include sea mammals (whales, dolphins, otters, seals and sea lions), marine reptiles such as sea turtles and saltwater crocodiles as well as invertebrates such as jellyfish and shrimp. The Great…
At noontime, the sky appears blue due to molecules in the atmosphere scattering blue light more efficiently than red. At sunrise and sunset, however, its color changes to red due to light having made its journey through an extended path through our atmosphere. There are various explanations as to why the sky is blue; some…
Spacecraft missions involve journeys by uncrewed spacecraft or robots to explore distant planets, moons, or objects within our Solar System. For instance, NASA Galileo provided evidence of liquid water on Jupiter’s moon Europa before being sent careening into Saturn’s atmosphere to prevent it from landing there and potentially polluting any underground lakes that might support…
Are you an animal enthusiast who adores rabbits? These fun facts about them will surely put a smile on your face! Rabbits possess dual eyes on both sides of their heads, giving them near 360-degree vision. Rabbits are prey animals in the wild, always on guard against potential predators. Therefore, they’ll run away, hide behind…
Spacecraft propulsion refers to how a space vehicle achieves forward movement. As there is no medium in space such as air, wings and fins are ineffective at maneuverability; electric thrusters may provide assistance instead. A rocket propels itself by pushing on the gas that ignites from its engines – this is a straightforward scientific fact…
After making its journey across Mars’ harsh atmosphere, a spacecraft successfully arrives at its destination and sends back information on its weather and geology. Curiosity has found evidence of long-lived, potentially habitable conditions in Gale crater on Mars and discovered minerals typically formed from water sources. Mangalyaan India’s Mars Orbiter Mission Mangalyaan outlived expectations after…
Those interested in spacecraft model kits have several places they can shop. Revell offers historical spacecraft like the Block 1 Command Service Module and Lunar Module which flew to the Moon. Other models available are Voyager 1 & 2, outer solar system mariners; Lunar Prospector; Galileo; Magellan; and Mars Global Surveyor – each requires careful…
