Since scientists started studying Mars, much has been learned about it. Robotic spacecraft have even orbited it and touched down on its surface. Mars is a smaller planet than Earth with lower mass, leading to reduced gravity forces and thus lower gravity forces on this world. Mass Mars, also known as “the Red Planet,” is […]

Spacecraft are vessels specifically engineered for travel and operation in outer space, featuring life support systems, science instruments and accommodations for crew. Some spacecraft are unmanned while others can carry people. Manned spacecraft are used to fly astronauts directly to the International Space Station and other planetary destinations while unmanned ones conduct scientific research. Aldrin

Spacecraft designers craft hardware specifically tailored for outer space travel. Ranging from orbiting satellites and space vehicles that travel between planets to missions that explore distant corners of space, each piece must withstand its challenging surroundings. After adopting a mission, detailed designs are drawn up and Engineering Models (EM) and Qualification Models (QM) constructed. These

Cheetahs (Acinonyx jubatus), like other wild animals, must fight for survival. Cheetahs hunt by sight from high points such as termite mounds or kopjes (small rocky hills). Predators feed on various antelope species, including Thomson’s gazelle and Grant’s gazelle as well as hares and birds. When encountering people, attacks will only occur out of self-defense.

As opposed to temperature and rainfall changes that leave their imprint in sedimentary layers, tree rings, or ice cores, clouds have the ability to dissipate quickly – and when this happens, computer simulations indicate that climate tipping points could result in 8 additional degrees of warming globally over the course of one century – this

Aerospace engineers design and test aircraft, spacecraft, satellites and missiles according to the Bureau of Labor Statistics. In addition, they may oversee manufacturing of these products and systems. Astronautical engineers design and construct spacecraft, the vehicles astronauts use to explore what remains mostly uncharted areas of space. This work can be both challenging and rewarding.

Every few weeks this year, astrological Mercury will appear to move retrogradely in the sky. Mercury governs communication, clear thinking and travel; when retrograded it can cause miscommunication and tech malfunctions that negatively impact daily life. As a general guideline, try not to enter into any major agreements or sign any new contracts during this

Ladybugs are beautiful insects to have around our gardens. Not only do they keep pesky insects at bay, they help our plants flourish by eating away at harmful aphids that would otherwise spread disease and disrupt growth. An interesting fact about them is their immunity to their own toxins! They will eat anything soft enough

Each sea turtle species has a specific diet depending on its habitat and available food sources, with different-shaped jaws to efficiently consume their favorite dishes. Green sea turtles feature finely serrated beaks to scrape algae off rocks and feed on seagrasses; hatchlings of these turtles are omnivorous. Hawksbills feature bird-like beaks for accessing cracks in
