Perseverance (rover)
''Perseverance'' is a car-sized Mars rover designed to explore the Jezero crater on Mars as part of NASA's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at 20:55 UTC. As of , ''Perseverance'' has been active on Mars for sols ( Earth days, or ) since its landing. Following the rover's arrival, NASA named the landing site Octavia E. Butler Landing. ''Perseverance'' has a similar design to its predecessor rover, ''Curiosity'', although it was moderately upgraded. It carries seven primary payload instruments, nineteen cameras, and two microphones. The rover also carried the mini-helicopter ''Ingenuity'' to Mars, an experimental technology testbed that made the first powered aircraft flight on another planet on April 19, 2021. On January 18, 2024 (UTC), it made its 72nd and final flight, suffering damage on landing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars 2020
Mars 2020 is a NASA mission that includes the rover ''Perseverance (rover), Perseverance'', the now-retired small robotic helicopter ''Ingenuity (helicopter), Ingenuity'', and associated delivery systems, as part of the Mars Exploration Program. Mars 2020 was launched on an Atlas V rocket at 11:50:01 Coordinated Universal Time, UTC on July 30, 2020, and landed in the Martian crater Jezero (crater), Jezero on February 18, 2021, with confirmation received at 20:55 UTC. On March 5, 2021, NASA named the landing site Octavia E. Butler Landing. As of , ''Perseverance'' has been on Mars for Sol (day on Mars), sols ( days, total days; ). ''Ingenuity'' operated on Mars for Sol (day on Mars), sols ( days, total days; ) before sustaining serious damage to its rotor blades, possibly all four, causing NASA to retire the craft on January 25, 2024. ''Perseverance'' is investigating an Astrobiology, astrobiologically relevant ancient environment on Mars for its Geology of Mars, surface ...

Microphone
A microphone, colloquially called a mic (), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers and other electronic devices, such as mobile phones, for recording sounds, speech recognition, Voice over IP, VoIP, and other purposes, such as Ultrasonic transducer, ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating Diaphragm (acoustics), diaphragm as a capacitor ...

Sol (day On Mars)
Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day. It is approximately 24 hours, 39 minutes, 35 seconds long. A Timekeeping on Mars#Martian year, Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days or 1.88 Earth years. The sol was adopted in 1976 during the Viking program, Viking Lander missions and is a unit of measurement, measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover. Length The average duration of the day-night cycle on Mars—i.e., a Martian day—is 24 hours, 39 minutes and 35.244 seconds, equivalent to 1.02749125 Earth days. The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. In specialised domains such as scientific research, navigation, and timekeeping, other standards such as Universal Time, UT1 and International Atomic Time (TAI) are also used alongside UTC. UTC is based on TAI (International Atomic Time, abbreviated from its French name, ''temps atomique international''), which is a weighted average of hundreds of atomic clocks worldwide. UTC is within about one second of mean solar time at 0° longitude, the currently used prime meridian, and is not adjusted for daylight saving time. The coordination of t ...

Curiosity (rover)
''Curiosity'' is a car-sized Mars rover Space exploration, exploring Gale (crater), Gale crater and Mount Sharp on Mars as part of NASA's Mars Science Laboratory (MSL) mission. ''Curiosity'' was launched from Cape Canaveral Space Force Station, Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 Coordinated Universal Time, UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than from the center of the rover's touchdown target after a journey. Mission #Goals and objectives, goals include an investigation of the Martian climate of Mars, climate and geology of Mars, geology, an assessment of whether the selected field site inside Gale has ever offered environmental science, environmental conditions favorable for Life on Mars, microbial life (including investigation of the Water on Mars, role of water), and planetary habitability studies in preparation for Human mission to Mars, human exploration.
