NASA’s newest and most advanced Mars rover has successfully collected its first rock sample for return to Earth, after the August attempt failed.

The Perseverance* rover’s chief engineer, Adam Steltzner, called it a perfect core sample.

“I’ve never been more happy to see a hole in a rock,” he posted on social media on September 2.

NASA’s rover team has now confirmed after further photographic review that last week’s drilling and collection resulted in Perseverance completing its first sample grab, tucking away the titanium tube containing the rock for its eventual return to Earth.

When Perseverance drilled into much softer rock a month ago, the sample crumbled and didn’t make it inside the titanium* tube. The rover drove approximately 800m to a better spot and tried again.

Initial photos taken on September 1 did show a sample in the tube but NASA confirmation was delayed when later images were inconclusive*. The sample is about the width of a pencil and more photos are planned.

Perseverance arrived in February at Mars’ Jezero Crater — thought to have been a lush lake bed and river delta billions of years ago — in search of rocks that might hold evidence of ancient life. NASA plans to launch more spacecraft to retrieve the samples collected by Perseverance and engineers are hoping to return as many as three dozen samples over the course of about a decade.

China has meanwhile developed a prototype* miniature helicopter for surveillance* work during its own Red Planet missions, following the historic landing of a Chinese robotic rover earlier in the year.

The prototype is similar in appearance to the robotic helicopter Ingenuity*, developed by NASA for the Perseverance mission, according to a photograph posted on the website of China’s National Space Science Center last week.

The agency said the helicopter could be a tool for China’s follow-up exploration of Mars, but did not give details.

The landing of China’s Mars rover in May began its first-ever mission on the planet, making it only the second country after the United States to get there. NASA’s Perseverance has been exploring Mars since February.

From the NASA rover, Ingenuity made its maiden flight in April, rising about 3m above the surface, marking humankind’s first ever successful deployment* of a powered aircraft in a world other than Earth.

The challenge for the 1.8kg Ingenuity is the thin atmosphere on Mars, which is just 1 per cent as dense as Earth’s.

To compensate* for the lack of aerodynamic* lift, NASA engineers equipped the miniature helicopter with rotor blades that are larger – 1.2m tip to tip – and spin faster than would be needed on Earth for an aircraft of its size.

Like Ingenuity, the Chinese prototype has two rotor blades, a sensor-and-camera base and four thin legs. But there is no solar panel at the top like Ingenuity, according to the photograph.

Ingenuity has made more than 10 outings since April, covering an overall distance of more than 2 km with flight time of about 20 minutes in all.

China is planning a crewed maiden mission to Mars in 2033.
