Indian rover begins to explore moon – DW – 08/24/2023
India's lunar rover began exploring the moon's surface on Thursday as part of the country's Chandrayaan-3 mission.
New Delhi's Vikram lander reached the moon on Wednesday, making India the first country to land a craft on the lunar south pole.
The six-wheeled, solar-powered Pragyan rover will explore the largely unmapped area of the moon and transmit images and scientific data over a period of two weeks. It will examine the mineral composition of the moon's surface.
Cahndrayaan-3 had to orbit the Earth several times to gain speed and took a month to reach the moon.
"Rover ramped down the lander and India took a walk on the moon!" the Indian Space Research Organisation (ISRO) posted on X, formerly known as Twitter. ...
23 million-year-old petrified mangrove forest discovered hiding in plain sight in Panama | Live Science
... Whereas the canopies of most living mangrove trees reach around 43 feet (13 meters) high, S. barrocoloradoensis grew to around 82 feet (25 m) and could tower up to 130 feet (40 m).
The ancient trees likely evolved the same survival strategies mangroves use today, preferring brackish waters to highly saline ocean waters, Jaramillo said. The forest fringed a narrow peninsula that connected present-day central Panama to North America before the Isthmus of Panama formed, sometime between 23 million and 3 million years ago.
The mangrove fossils were all in a similar state of preservation, prompting the researchers to think the forest was wiped out by a single volcanic eruption that flooded the landscape with mud.
Since the researchers first discovered wood fossils on Barro Colorado Island, "people have been finding plenty more all over the island," Jaramillo said.
