NASA's Mars helicopter soars past 1-mile mark in 10th flight over Red Planet | Space

The small chopper surpassed the 1-mile (1.6 km) mark of its total flight distance on Saturday (July 24) when soared over a rocky region called "Raised Ridges" at its Jezero Crater home.

Flight 10 was the most challenging yet for Ingenuity, with 10 different waypoints for the helicopter to hit as it flew over its "Raised Ridges" target. It reached a maximum altitude of 40 feet (12 meters), a new record height, and flew about 310 feet (95 m).

Nasa probe determines Mars' internal structure - BBC News

Scientists say they now have some absolute numbers to describe the internal rock structure of Mars.

The Nasa-led mission reveals the average thickness of Mars' crust to be between 24km and 72km - somewhat thinner than had been expected.

But the key finding is the size of the planet's core. Its radius of 1,830km is at the top end of previous estimates.

RAGBRAI 2021 departs Le Mars with more than 15,000 riders on route

The 2020 edition of RAGBRAI was canceled because of the COVID-19 pandemic, the first time the annual, seven-day ride hadn't been held since its founding in 1973. For many riders, its return felt like a dose of freedom after the long months of isolation, quarantine and maintaining social distance.
