I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#3 spacecraft arriving in quick succession” CAPE CANAVERAL, Fla. — After hurtling hundreds of millions of miles through space since last summer, three robotic explorers are ready to hit the brakes at Mars. The stakes — and anxiety — are sky high. The United Arab Emirates’ orbiter reaches Mars on Tuesday, followed less than 24…
“#6 surprising ways satellites make our lives simpler” Almost 3,000 operational spacecraft orbit our Earth. This number is growing constantly, thanks to cheaper materials and smaller satellites. Having this many satellites in orbit can create problems, including space junk and the way they change our view of the night sky. But satellites provide a vital…
“#These self-sufficient robots can have ‘babies’ and colonize distant planets” It’s been suggested that an advance party of robots will be needed if humans are ever to settle on other planets. Sent ahead to create conditions favorable for humankind, these robots will need to be tough, adaptable, and recyclable if they’re to survive within the…
“#‘Space law’ helps prevent earth’s microbes from polluting other planets” There are two planned Mars landings in 2021. First, NASA’s Perseverance rover is due to land on the planet later this month. Then China’s Tianwen rover will follow in May. Both missions intend to search the planet for signs of life. But how do we…
“#Gaseous mix up: Scientists thought there could be life on Venus, but there’s not” In September 2020, astronomers announced the possible detection of phosphine on Venus. On our own world, phosphine is mostly produced by life, and the detection of this gas in the atmosphere of Venus could have been an intriguing hint of alien…
“#Japan scientists to study source of high heat on asteroid” TOKYO — Japanese space experts said Thursday they will examine soil samples brought back from a distant asteroid in an attempt to find the source of heat that altered the celestial body, in their search for clues to the origin of the solar system and…
“#Virgin Orbit launched a rocket from a plane — here’s how” Earlier this month, ten cubesats – small, cheap satellites weighing about a kilogram each – were sent into orbit around Earth. With almost 1,500 of these small satellites launched so far, adding another ten might seem trivial. But this was no ordinary launch. Instead…
“#Elon Musk’s SpaceX unveils plans for historic all-civilian mission to space” Elon Musk‘s SpaceX plans to launch the world’s first all-civilian mission to orbit later this year, the aerospace firm announced on Monday. The journey will last for several days and the spacecraft will do a full orbit around the Earth every 90 minutes. This should…
“#Spacewalkers complete 4 years of power upgrades for station” CAPE CANAVERAL, Fla. — A pair of spacewalking astronauts completed a four-year effort to modernize the International Space Station’s power grid on Monday, installing one last battery. Over the weekend, flight controllers in Houston used the space station’s big robot arm to replace the last pair…
“#Satellites orbiting Earth are increasing like crazy — how do we prevent them from crashing?” In recent years, satellites have become smaller, cheaper, and easier to make with commercial off the shelf parts. Some even weigh as little as one gram. This means more people can afford to send them into orbit. Now, satellite operators…
