For most of the 20th century, scientists thought the Moon’s surface was bone-dry. The 382 kilograms of rock and soil samples brought by the Apollo missions to Earth attested to this. When they did ...

The farside also lacked the Moon’s familiar dark splotches. Formed as a result of active volcanism over 3 billion years ago, it was anyone’s guess why dark lava plains cover about 31% of the nearside ...

India has formally approved the joint ISRO-JAXA Chandrayaan 5 (LUPEX) mission to study water ice on the Moon’s south pole. The mission and its approval are notable in many ways as we’ll see below.

Where did our Moon come from? The origin of our cosmic neighbor is a fundamental question in planetary science. From Galileo’s first telescopic observations of the Moon to humans walking on its ...

The Moon is host to a type of bright feature quite glaringly called swirls. Here is the lunar swirl of Reiner Gamma. Beautiful and bright lunar swirl of Reiner Gamma. It spans well over a hundred ...

How will ISRO go from Chandrayaan 3 to an Indian on the Moon? Clarifying and laying down India’s plans for increasingly complex robotic lunar missions, where human spaceflight comes in, and what ...

Here’s an attempt at a neutral overview of India’s first Mars mission and its actual impact, one which doesn’t stick to its cost effectiveness at any cost. ISRO originally intended to launch ...
