By artfully manipulating archiveal footage, Apollo 11 manages to be captivating without becoming overly sentimental. This film offers a far superior account of this monumental event than last year’s visually captivating but emotionally superficial First Man. It humanizes this staggering success that may be deeply embedded into American culture but which transcends it and brings…
An explosion on board a spaceship can be terrifying for astronauts and potentially hazardous to satellites nearby. America watched in horror in January 1986 as the space shuttle Challenger exploded during liftoff, killing seven astronauts including Christa McAuliffe of NASA’s Teacher in Space program. A suitcase-sized piece of insulating foam fell from an external tank…
Manmade objects orbiting Earth are vast, from those used to observe our planet itself to others that study Mars, asteroids or even distant stars. Satellites remain in orbit by using fuel to balance their tendency toward flight into space with Earth’s gravitational pull and maintain their velocity in orbit. Satellites From a distance, satellites resemble…
Satellite weather is a great way to see the current weather conditions. You can view a variety of weather data on this page, including temperature, precipitation, wind speed and more. The tourism score favors clear, rainless days with perceived temperatures between 65degF and 80degF. Based on this score, the best times of year to visit…
Namibia is a country in southern Africa, with the Atlantic Ocean to its west and Botswana and South Africa to the east. Its capital and largest city is Windhoek. Its climatic conditions are characterized by hot, dry weather with persistent droughts and erratic rainfall patterns. It ranks as one of the driest countries in sub-Saharan…
Space exploration has many benefits to society, including improving technology, creating jobs, and advancing medical science. However, space exploration is also expensive, risks the lives of astronauts, and creates pollution and space debris. Some people may wonder whether space exploration is worth the risks and costs. But these people need to be aware that the…
Solar power is a vital source of energy for spacecraft. Without electricity, they won’t be able to take pictures, collect information and send back data to Earth. It could also be a way to get reliable, clean energy to people living in remote areas, rather than relying on fossil fuels that are finite and can…
Weather satellites provide meteorologists with the data they need to make accurate, life-saving forecasts. These satellites continuously orbit above us, providing atmospheric observations that are ingested into numerical weather prediction (NWP) computer models. Environmental satellites also have imaging capabilities that allow meteorologists to watch storms develop from space, enabling them to identify volcanic ash and…
Weather satellites take a picture of the entire world every 5 to 15 minutes. The pictures are animated so you can see changes in cloud cover and wind speeds as they happen. Hurricane Dorian hit the Bahamas on Sunday and left behind devastation that lasted for days. That’s why satellite images, especially synthetic aperture radar…
