Cryptocurrency is a decentralized digital currency. There is no physical money associated with it; it is created on and only exists on the blockchain, so it is a virtual asset. Like most financial assets, it gets its value based on the trust people put in it to be worth something now and in the future, like shiny golden rocks called gold, or pieces of paper with the picture of a president on them called dollars. Long ago, people used shells and beads as financial assets. ❏ Cryptocurrency gets its name from the word cryptography, the science of protecting computer information using mathematics. ❏ Cryptocurrency on the blockchain is assigned to an owner and is accessed via the owner’s cryptocurrency wallet. ❏ Bitcoin was the first cryptocurrency. It was originally designed to be used as a direct peer-to-peer electronic cash system allowing users to hold a form of currency and make transactions directly with each other without the need for a trusted third party such as a bank or credit card company to be involved in the transaction. 5 What Is Cryptocurrency ❏ There is no central authority controlling cryptocurrency holdings or transactions such as a bank, credit card company or a government. They are unable to manipulate, interfere or stop a blockchain on which cryptocurrencies operate. ❏ Unlike government issued money (fiat currency) that has a stable value, most cryptocurrencies have no stable value and are only worth what people are willing to pay for them; therefore, their value is constantly fluctuating, sometimes wildly, due to the speculative nature of the market. Some cryptocurrency, called stable coins, are pegged 1:1 with fiat currency, most commonl

The Legacy of Mariner: Exploring the Red Planet The Mariner missions, spearheaded by NASA, have been instrumental in advancing our understanding of the Red Planet - Mars. Among these, Mariner 4, 6, 7, and 9 stand out for their groundbreaking discoveries and the technological marvels they represented. Mariner 4 (1964-1965) The first spacecraft to successfully fly by Mars, Mariner 4 sent back the first images of another planet from deep space. These 21 images, though grainy, provided invaluable insights into the Martian atmosphere and surface. Mariner 6 and 7 (1969) These twin missions were designed to fly over the equator and southern hemisphere of Mars. Together, they sent back 201 detailed photos, revealing vast, desert-like plains and the planet's thin atmosphere. Mariner 9 (1971-1972) Mariner 9 became the first spacecraft to orbit another planet. It revealed the vastness of the largest volcano in the solar system, Olympus Mons, and the deep, canyon-like structure, Valles Marineris. The spacecraft also discovered evidence of water erosion and ancient riverbeds, hinting at the possibility of past life. Conclusion The Mariner missions laid the foundation for future Mars exploration, painting a picture of a planet with a rich geological history and potential for life. As we continue our quest to understand our neighboring planet, the legacy of Mariner serves as a beacon of human achievement and curiosity.
