From Dust to Meteorite
Meteors and meteorites Meteors and meteorites are two nouns which in fact define the same interplanetary object, with the difference that the second reaches the ground, as we explained in the page dedicated to meteoroid classes. Both are meteoroids originating from the decay of comets or fragments of asteroids and were formed billions of years ago. Most meteorites are microscopic and vaporize in dense layers of the atmosphere. The fragments which have withstood atmospheric friction are usually “heavy weights”, remnants of rocks originally measuring a few centimeters to several tens of meters in diameter and weighing up to several hundred tons. Of course, such meteorite falls are extremely rare, and it is fortunate for the human species. How many meteorites fall on Earth? With each passing day, millions of microparticles of a tenth of a millimeter cover the earth’s surface. The quantity of meteoroids hitting the upper atmosphere each day varies between 0.4 and 110 tonnes per day with an estimated maximum of 300 tonnes per day (cf. CS Gradner et al., 2014), which brings the average to 33 tonnes depending on the NASA. Most of this dust burns in the atmosphere and does not reach the ground

Mars: A Thought Experiment
Introduction Climate change, global warming, environmental destruction it doesn't matter what you call it. Human beings are destroying this earth at an unprecedented rate. Naturally people are looking for solutions, looking to the stars to quench their imaginations for survival. They see an opportunity to start over. To possibly take what humanity has learned for thousands of years. Evolution spinning its web of inter-species connection, providing for the perfect environment for apes to become human. Much like the planet itself a seemingly Goldie Locks scenario for natural selection. Ending in a hyper conscious species that has imprinted its history onto the landscapes of planet earth.

Summer Space Reading List: The Interstellar Age
The 1960s and 70s were inspirational times for young nerds, like me. Hard science fiction from Robert Heinlein, Larry Niven, and Jerry Pournelle drove my passion for an exciting human future in space. Isaac Asimov’s prolific output of science essays and books grounded that passion. Real world space exploits by NASA operationalized it. America’s national space agency seemed to be everywhere at once during that period; going to moon, building an orbital space plane, and exploring the solar system from Mercury to Neptune! Three NASA programs strongly influenced my personal goal to eventually to secure a career in the space world: the Apollo Moon landings, the Viking Mars landing, and the exploration of the outer solar system by the Voyager probes. The two Voyager spacecraft, launched in 1977, were particularly influential to me because their missions occurred when I was a teenager, that important time in one’s life when you are young enough to be amazed by technology but finally educated enough to grasp some of the science behind it. I wasn’t the only one captivated by these robots. The Voyagers were immortalized in Star Trek: The Motion Picture, a film that required me to ditch a day of high school and wait in line for eight hours in order catch the first showing. While I was pleased to see the Star Trek future included funding for six Voyager missions (alas, there were only the two), it was less heartening to see one them going postal; V’Ger returns from interstellar space to threaten the Earth with a destructively high-powered delivery of its research findings. On a more positive note, real Voyager images also inspired the flyby sequences of Jupiter and Saturn in the original opening sequence of the Star Trek: Next Generation TV series. Of course, most of the Voyager excitement occurred back in the 80s when I was busy being an entrepreneur in the software, computer, and networking space. I didn’t have direct access to the cool kids from the Jet Propulsion Laboratory, like I do now. I eagerly followed the Voyager flybys of Jupiter (1979), Saturn (1981), Uranus (1986), and Neptune (1989) in newspaper and magazine stories (sigh, no Internet kids). It was Jim Bell’s description, over a recent dinner with colleagues, of the challenges he had in recording the audio version of The Interstellar Age that reminded me of my love for those missions and prompted me to take up the audio version of his 2015 book. I’m a fan of many excellent voice actors who do audiobook narrations. I particularly love Wil Wheaton’s narration of modern Sci Fi classics. However, when an author does the reading of his or her own work, the result can be fantastic, and I was not disappointed here. With The Interstellar Age on audio, I know the pronunciations are precise, as in not saying “probing Uranus” as gleefully as the proverbial twelve-year-old. A good, author-read audiobook can also conveys subtle humor from text to the listener. My favorite humorous anecdote appears when Jim discusses the “grand adjectives of exploration.” These are the words like “plucky”, “intrepid,” or “courageous” which are often applied to our favorite space robots by the media. Of course, the Voyagers are simply doing what they were built to do so long ago and executing the code that we send to them. They are unaware of the frightening risks they face, a given requirement for sentient beings who aspire to be plucky, intrepid, or courageous! However, this harsh reality doesn’t stop us science fanboys from loving metallic space critters, so Jim must set us straight with the advice of Voyager Project Manager John Casani, “Don’t anthropomorphize the spacecraft, they don’t like it.”

The Starry Night
No matter how far along you are in your sophistication as an amateur astronomer, there is always one fundamental moment that we all go back to. That is that very first moment that we went out where you could really see the cosmos well and you took in the night sky. For city dwellers, this is a revelation as profound as if we discovered aliens living among us. Most of us have no idea the vast panorama of lights that dot a clear night sky when there are no city lights to interfere with the view.

The world's wealthiest person Musk has also moved into a "container," indicating that the trend of small residences is on the rise.
Thoreau would sit in the sun at the doorway of a log cabin by the lake from daybreak until noon, after taking his normal bath, meditating alone, surrounded by pine, hickory, and sumac trees, in quiet. And the birds would sing till the sun shined through his west window, reminding him of how quickly time had passed. He grew like corn at night back then.

Top 10 facts about Moon
(1). Moon is not a planet, it is a satellite: There is a difference between a planet and a satellite. Moon is a satellite of Earth. Similarly, Saturn, Jupiter, and Pluto also have satellites i.e. moon. According to scientists, there are satellites larger than the moon, of which the largest is located near the planet Jupiter, Kalisto. Apart from this, Titan and Eo of Saturn are also bigger than the Moon. Moon is also called a fossil planet.

55 Cancri e - the Diamond Exoplanet
Among the exoplanets discovered so far, one of them seems to stand out by a special characteristic. It is located in the constellation Cancer, at a distance of about 40 light-years away from the Earth, which in cosmic terms, is very near to our planet. When the night sky is free of clouds, the host star of this exotic planet is visible to the naked eye. The name of the exotic planet is 55 Cancri e and scientists have concluded that it is made of diamonds. The term exoplanet defines any planet that is situated outside the Solar System. 55 Cancri e revolves in only 18 hours around a star called 55 Cancri A. Its size is twice the size of Earth and its surface is extremely hot, at about 5000 degrees Fahrenheit or 3000 degrees Celsius. 55 Cancri e has eight times the mass of our planet and this is why it is also called the super-Earth. The planet is believed to be a carbon planet. No water has been discovered on its surface, but helium and hydrogen were detected.
