“Perseverance”

Image composed of 62 individual images

The NASA picture shows the selfie with the helicopter.

Taking a selfie in special places is obviously not just for people: On Mars, the NASA rover “Perseverance” took a photo of itself with the mini-helicopter “Ingenuity”.

The US space agency published the photo on Wednesday (local time) and wrote that “Perseverance” took it with its robotic arm, but that it was actually composed of 62 individual images.

Heli soon with first flight over Mars

Next to the rover in the foreground of the picture you can see the small helicopter “Ingenuity”, which is about four meters away from the vehicle and is supposed to make its first flight on the red planet in the coming days. The 1.8 kilogram “Ingenuity” (in German: ingenuity) is to rise to a height of about three meters in its first test flight, hover there for thirty seconds and then land again on the surface of Mars. It would be the first flight of an aircraft on another planet. For around a month, the “Ingenuity” powered by lithium-ion batteries could make several more flight attempts.

Minus 90 degrees on the red planet

The helicopter has to defy extreme conditions: On Mars it is cold down to minus 90 degrees Celsius at night, the gravitational pull of the planet is also lower and the atmosphere is much thinner. The mini-helicopter was placed in the belly of “Perseverance” at the end of February – after 203 days of flight and 472 million kilometers traveled – with a risky maneuver in a dry Mars lake called “Jezero Crater”. “Perseverance” is to investigate this lake with a diameter of around 45 kilometers over the next two years.
