What Did Scientists Discover on Mars?

As of my last update in September 2021, there have been several significant discoveries on Mars made by various spacecraft and rovers. However, keep in mind that the information provided here may not include the latest discoveries beyond that date.

Presence of Water:The presence of water reflects time, eternally in motion, and mirrors the ebb of tides as a central metaphor to this sensuous story of one woman's voyage to Italy. Scientists have found strong evidence of past water flow on Mars, including river valleys, lakebeds, and minerals that can only form in the presence of liquid water.

Seasonal Changes: the change from winter to spring, spring to summer, etc.Spring flower blooms, summer heat waves, freeze and thaw, growing seasons, and animal migrations are all examples of natural phenomena that follow seasonal patterns.Observations by the Mars Reconnaissance Orbiter (MRO) and other missions have revealed seasonal changes, such as the appearance and disappearance of dark streaks called "recurring slope lineae," believed to be formed by flowing briny water.

Methane Detection: Methane detection sensitivity refers to the size of a methane leak (i.e., the “emission rate”, or how much gas is escaping from a leak over a given time) that can be detected by a technology solution.Various missions, including the Curiosity rover, have detected traces of methane in the Martian atmosphere. Methane is interesting because it could potentially be a sign of biological activity, although other non-biological processes could also produce it.

Organic Molecules: A molecule of the kind normally found in living systems. Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.NASA's Curiosity rover found organic molecules in ancient rocks on Mars. These molecules are the building blocks of life, although they don't necessarily indicate life itself.

Perseverance Rover's Discoveries: The Perseverance rover, which landed on Mars in February 2021, has been actively exploring the Jezero Crater. It has already identified rocks with signs of past water activity and collected core samples that could potentially contain evidence of ancient microbial life.Latest Astonishing Discovery by NASA's Perseverance Mars Rover. Evidence left in rocks is leading scientists to rethink what watery environments looked like on ancient Mars. New images from NASA's Perseverance rover reveal evidence of a powerful river on Mars, possibly deeper and faster-moving than previously known.

Ingenuity Helicopter: The Ingenuity Mars Helicopter is a small aircraft carried to the surface of the Red Planet attached to the belly of the Perseverance rover. Ingenuity's mission is experimental in nature and completely independent of the rover's science mission. The Ingenuity helicopter, also part of the Perseverance mission, made history as the first powered flight on another planet, demonstrating the feasibility of aerial exploration on Mars.

Marsquakes:A marsquake is a quake which, much like an earthquake, would be a shaking of the surface or interior of the planet Mars as a result of the sudden release of energy in the planet's interior, such as the result of plate tectonics, which most quakes on Earth originate from, or possibly from hotspots such as Olympus Mons . NASA's InSight lander has been studying "marsquakes" to understand the planet's interior and geology better.

It's important to note that Mars exploration is an ongoing process, and new discoveries are continuously being made as more missions are launched and existing ones continue their operations. For the latest information, I recommend checking official sources like NASA or other space agencies' websites.
