A space helicopter made by NASA in the United States flew in the Mars sky for the first time yesterday (19th).
Until now, the Mars exploration area, which has been conducted only by unmanned vehicles on the surface, is expected to expand dramatically.
Reporter Jung Hye-kyung reports.

50cm high helicopter floats above the surface of Mars like a wasteland.
At around 3:30 a.m. on the 19th of the US local time, NASA's space helicopter'Injenewity', developed by NASA, succeeds in its first powered flight on Mars.
In this test flight, Ingenuity went up to a height of about 3m at a speed of 1m/s after take-off and made a stop flight for 30 seconds before landing.
On Mars, the air density is only one hundredth of the Earth, making it difficult to fly using floating forces.
So far, exploration to Mars has been carried out as an unmanned vehicle equipped with equipment such as a camera and moving around the surface.
Ingenuity overcomes these environmental constraints by increasing the rotational speed 8 times with carbon fiber blades.
This success is said to be a significant watershed for exploration on Mars.
[Thomas Zuberchen/Dr., NASA's Science Mission: We haven't actually been able to closely observe Mars because we can't reach it.
Now we can imagine humans exploration with flying fuselage in the future.]
NASA says Ingenuity will be tested four more times in the future.
