Increíble este buscador "respondetodo" Haz una pregunta - matemáticas, cálculos, conversiones, ciencias, geografía, vale casi todo - y, voilà, WolframAlpha te responde. Muy bueno. A continuación, un resumen en inglés. Free online access to the Wolfram|Alpha computational knowledge engine:answer questions; do math; instantly get facts, calculators, unit conversions, and real-time quantitative data and statistics; create plots and visualizations; and access vast scientific, technical, chemical, medical, health, business, financial, weather, geographic, dictionary, calendar, reference, and general knowledge-and much more.

The Mars 2020 Perseverance Rover will search for signs of ancient microbial life, which will advance NASA's quest to explore the past habitability of Mars. The rover has a drill to collect core samples of Martian rock and soil, then store them in sealed tubes for pickup by a future mission that would ferry them back to Earth for detailed analysis. Perseverance will also test technologies to help pave the way for future human exploration of Mars. Strapped to the rover's belly for the journey to Mars is a technology demonstration - the Mars Helicopter, Ingenuity, may achieve a "Wright Brothers moment " by testing the first powered flight on the Red Planet. Searching for Ancient Life, Gathering Rocks and Soil There are several ways that the mission helps pave the way for future human expeditions to Mars and demonstrates technologies that may be used in those endeavors. These include testing a method for producing oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing weather, dust, and other potential environmental conditions that could affect future astronauts living and working on Mars.
