In less than 2 days, NASA expects to launch the Mars 2020 Perseverance mission from Cape Canaveral, Florida. Loaded with scientific instruments, advanced computational capabilities for landing, and other new systems, the Perseverance rover is the largest, heaviest, most sophisticated vehicle NASA has ever sent to the Red Planet. "Perseverance sets a new bar for our ambitions at Mars," said Lori Glaze, planetary science director at NASA Headquarters in Washington. "We will get closer than ever before to answering some of science's longest-standing questions about the Red Planet, including whether life ever arose there." What drives Perseverance's mission and

History and evolution of memory cards A memory card is an electronic data storage device used for storing digital information, typically using flash memory. Read about the history and evolution of memory cards, their advantages and disadvantages, and the future of flash memory in this blog post. What is flash memory and where is it used? Flash memory is a compact, widely used electronic storage medium, that can be electrically erased and reprogrammed. It can store data for long periods of time without being connected to a power supply (its memory is non-volatile, unlike RAM). There are two types of flash memory, using the same basic technology with slightly different ways of reading and writing data – NAND and NOR flash memory. Flash memory cards are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptops, computers, tablets, PDAs, portable media players, video game consoles, etc. Basically, it is hard to go a day without using at least one device
