The six-wheeled Pragyan lunar rover weighing 26 kg traveled practically 103 meters.
The moon we see right this moment was as soon as a sizzling molten ball, a significant discovery confirmed by the ISRO Chandrayaan-3 science staff.
The staff has launched the primary science outcomes from the Pragia rover’s devices flying towards the moon. The landmark paper was revealed right this moment within the prestigious British Journal of Science. “Nature” journal solely publishes main scientific breakthroughs.
The paper’s lead creator, Dr. Santosh V. Vadawale, a scientist on the Bodily Analysis Laboratory (PRL) in Ahmedabad, led a staff of practically three dozen scientists. “By analyzing lunar soil, our staff confirmed that the moon was as soon as a part of the Moon,” he stated, a lava ball about 4.4 billion years in the past, shortly after its delivery.
It is referred to as the lunar magma ocean (LMO) speculation. Consultants speculate {that a} planetary physique the scale of Mars struck the Earth about 4.5 billion years in the past, inflicting materials to be ejected excessive into the sky after which merge to type the moon. “The primitive moon was all molten magma, like what we see within the Earth’s core, at about 1,500 levels Celsius,” Mr Wadawale stated.
When India made landfall at Shiv-Shakti level close to the South Pole, it created international historical past as no different nation had ever landed on this space and it was identified that no matter Indian scientists found can be novel. Curiously, the fundamental composition of lunar soil just isn’t that completely different from soils seen on Earth, Mr. Wadawale stated. Since there is no such thing as a weathering on the moon, the invention additionally supplies a glimpse into the lengthy historical past of the photo voltaic system.
Chatting with NDTV, ISRO Chairman Dr S Somanath stated, “Chandrayaan-3 not solely proved India’s technological and engineering prowess via its mushy touchdown, however now this landmark scientific paper revealed within the prestigious journal Nature demonstrates , India has additionally performed groundbreaking scientific evaluation by offering its first inner information.

The 26-kg six-wheeled Pragyan lunar rover traveled practically 103 meters on the lunar floor throughout its 10-day life cycle. It travels at a velocity of 1 centimeter per second.
“Evaluation of lunar soil at excessive latitudes within the southern a part of the moon utilizing information from India’s Chandrayaan-3 mission suggests the presence of remnants of a former magma ocean,” Nature journal stated in a press release.
Including that earlier research of lunar geology have relied totally on samples collected by mid-latitude lunar missions, such because the Apollo program. Nevertheless, in August 2023, India’s Vikram lander (a part of the Chandrayaan-3 mission) efficiently made a mushy touchdown close to the moon’s south pole. The Pragyan rover then made 23 measurements at completely different areas alongside a 103-meter-long space of the lunar floor utilizing its onboard alpha-particle X-ray spectrometer, which measures the fundamental composition of lunar regolith, or lunar soil.
Santosh Vadawale and colleagues analyzed Pragyan’s measurements and located that the fundamental composition of the lunar regolith surrounding the lander was comparatively homogeneous and contained primarily rocky anorthosite. They famous that compositional measurements on the Moon’s South Pole are between these of samples collected from the Moon’s equatorial areas by the Apollo 16 and Luna-20 missions. The authors counsel that the same chemical compositions of those geographically distant samples assist the lunar magma ocean speculation.
On this speculation, because the Moon cooled throughout its formation, much less dense anorthosite would have floated to the lunar floor, whereas heavier minerals would have sunk to type the mantle. Dr. Vadawale and colleagues consider that the magnesium minerals additionally detected by Pragyan (which can’t be defined by the lunar magma ocean speculation) are probably deeper materials excavated by the close by South Pole-Aitken impression.
The authors concluded that the composition of the Vikram touchdown website is in line with the LMO speculation, which predicts that the lunar highlands shaped because of the floating of lighter anorthositic rocks.
For the reason that elemental composition of lunar soil just isn’t that completely different from the soil we see on Earth, this landmark discovery by Chandrayaan-3 opens up the potential of farming on the moon utilizing the identical lunar regolith that may be used for everlasting habitation. alternative. The expansion of indoor vegetation shall be managed and naturally water and natural matter must be added.
