Mars: April 2021



NASA's Ingenuity Mars Helicopter is two days away from making humanity's first attempt at powered, controlled flight of an aircraft on another planet.


NASA's Perseverance Mars rover took a selfie with the Ingenuity helicopter, seen here about 13 feet (4 meters) away in this image from April 6, 2021, the 46th Martian day, or sol, of the mission.


Evening temperatures at Jezero Crater can plunge as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius), which can freeze and crack unprotected electrical components and damage the onboard batteries required for flight.


Within a few days, Ingenuity will be on the surface of Mars. Until now it has been connected to the Perseverance rover, which allowed Ingenuity to charge its battery as well as use a thermostat-controlled heater powered by the rover.


Researchers from Brown University have discovered a previously unknown type of ancient crater lake on Mars that could reveal clues about the planet's early climate.
