If any factor regarding the lander module appears unfavourable, then the landing will be shifted to August 27, said the Space Applications Centre-ISRO about Chandrayaan-3 on Monday. 

Nilesh M Desai, director of Space Applications Centre-ISRO, Ahmedabad said that the decision regarding the landing will be taken based on the health of the lander module and the conditions on the Moon.

“On August 23, two hours before Chandrayaan-3 lands on the Moon, we will decide on whether or not it will be appropriate to land it at that time based on the health of the lander module and the conditions on the Moon. In case, if any factor appears to be not favourable, then we will land the module on the Moon on August 27. No problem should occur and we will be able to land the module on August 23,” Director Desai said.

ISRO Chairman and Secretary Department of Space S Somanath called on the Union Minister of State (Independent Charge) Science and Technology, Atomic Energy and Space Jitendra Singh in New Delhi today and apprised him of the status and readiness of ‘Chandrayaan-3′ for the moon landing scheduled on August 23, 2023.

Chairman ISRO briefed the minister on the health status of Chandrayaan-3 and said that all systems are working perfectly and no contingencies are anticipated on Wednesday.

In the next two days, the health of Chandrayaan-3 will be continuously monitored. The final sequence of landing will be loaded two days ahead and tested out, he said.

During the meeting, Minister Jitendra Singh expressed his confidence in ‘Chandrayaan-3′ making a soft landing this time and hoped that it will script a new history of planetary exploration under the guidance of Prime Minister Narendra Modi.

ISRO said the Chandrayaan-3 is set to land on the moon on August 23, 2023, around 18:04 hours IST.

Live actions will be available on the ISRO website, its YouTube channel, Facebook, and public broadcaster DD National TV from 17:27 IST on Aug 23, 2023.

While the Chandrayaan-2 mission was only “partially successful” since the lander lost contact after a hard landing, the ISRO successfully established two-way communication between the Chandrayaan-3 lander module and the still-orbiting Chandrayaan-2 orbiter. In a significant development, the Chandrayaan-2 orbiter which was already fixed around the moon established a two-way connection with the lander module of Chandrayaan-3 on Monday.

Earlier today, the ISRO shared new images of the lunar far side area captured by the Chandrayaan-3.

India will be the fourth country in the world to achieve this feat after the United States, Russia, and China, but India will be the only country in the world to land on the lunar south pole.

The primary objectives of the Chandrayaan-3 mission are threefold — to demonstrate safe and soft landing on lunar surface; to demonstrate rover roving on the moon, and to conduct in-situ scientific experiments.

Chandrayaan-3’s development phase commenced in January 2020 with the launch planned sometime in 2021. However, the Covid-19 pandemic brought an unforeseen delay to the mission’s progress.

Jitendra Singh recalled that the first in the series of Chandrayaan — namely Chandrayaan-1, is credited for having discovered the presence of water on the surface of the Moon, which was a new revelation for the world and even the premier Space agencies like the USA’s NASA (National Aeronautics and Space Administration) were fascinated by this discovery and used the inputs for their further experiments.

Chandrayaan-3 mission was launched on July 14, 2023, via the GSLV Mark 3 (LVM 3) heavy-lift launch vehicle from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota at 2:35 PM.

Ahead of the much-awaited soft landing of Chandrayaan-3 on the south pole of the Moon, former director of the Indian Space Research Organisation (ISRO) and in-charge of the previous lunar mission ‘Chandrayaan-2′, K Sivan earlier today said that the mission will be a “grand success”.

“It’s a very anxious moment…I’m sure that this time it will be a grand success,” Sivan said while speaking to ANI.

“We have our own system and we will be establishing a soft landing without any problem. But it is a complex process,” he said while responding to a question asked whether there would be any impact after the failure of Russia’s Luna-25 mission. Russia’s moon mission failed after its Luna-25 spacecraft spun out of control and smashed into the moon on Sunday.

He said that corrective measures have been taken after going through data generated by the Chandrayaan-2 mission. When asked if those additional systems too were indigenous, Sivan said, “Everything is indigenous.”

Earlier today, ISRO released images of the lunar far side area captured by the Lander Hazard Detection and Avoidance Camera (LHDAC). This camera assists in locating a safe landing area — without boulders or deep trenches — during the descent.

Notably, the ‘Vikram’ lander module of the spacecraft successfully separated from the propulsion module recently, and subsequently underwent crucial deboosting manoeuvres and descended to a slightly lower orbit. The Chandrayaan-3 mission’s lander is named after Vikram Sarabhai (1919–1971), who is widely regarded as the father of the Indian space program.

A GSLV Mark 3 (LVM 3) heavy-lift launch vehicle was used for the launch of the spacecraft that was placed in the lunar orbit on August 5 and since then it has been through a series of orbital manoeuvres been lowered closer to the moon’s surface.

It has been a month and seven days since the Indian Space Research Organisation launched the Chandrayaan-3 mission on July 14. The spacecraft was launched from the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota.

The stated objectives of Chandrayaan-3, India’s third lunar mission, are safe and soft landing, rover roving on the moon’s surface, and in-situ scientific experiments.

The approved cost of Chandrayaan-3 is Rs. 250 crores (excluding launch vehicle cost).

Chandrayaan-3’s development phase commenced in January 2020 with the launch planned sometime in 2021. However, the COVID-19 pandemic brought an unforeseen delay to the mission’s progress.

The key scientific outcomes from Chandrayaan-2 include the first-ever global map for lunar sodium, enhancing knowledge on crater size distribution, unambiguous detection of lunar surface water ice with IIRS instrument, and more.

Musk's Neuralink Will Test Brain Chips in Clinical Study in Great Britain

Elon Musk’s brain implant company Neuralink said on Thursday it will launch a clinical study in Great Britain to test how its chips can enable patients with severe paralysis to control digital and physical tools with their thoughts.

The company is partnering with the University College London Hospitals trust and Newcastle Hospitals to conduct the study, it said in a post on X.

Neuralink said patients living with paralysis due to conditions such as spinal cord injury and a nervous system disease called Amyotrophic Lateral Sclerosis (ALS) qualify to participate in the study.

The company raised $650 million (roughly Rs. 5,676 crore) in its latest funding round last month. It began human trials in 2024 on its brain implant after resolving safety concerns flagged by the US Food and Drug Administration, which had initially rejected Neuralink’s application in 2022.

According to the company, five patients with severe paralysis are currently using its device to control digital and physical tools with their thoughts.

Neuralink, founded in 2016, has raised about $1.3 billion (roughly Rs. 11,360 crore) from investors and is valued at roughly $9 billion (roughly Rs. 78,714 crore), according to media reports, citing PitchBook.

MIT Just Proved Einstein Wrong in the Famous Double-Slit Quantum Experiment

Physicists at MIT conducted a precise version of the renowned double slit quantum experiment, which challenges Einstein’s objections to quantum mechanics. With the help of ultracold atoms and single photons, they have shown the reaction of the long-standing wave-particle duality discussion without traditional spring setups. The researchers ignored the classical apparatus components and allowed nature’s inherent uncertainty to unleash Bohr’s complementarity, as both wave and particle-like behaviour cannot be observed simultaneously. The finding matches the quantum theory and disagrees with Einstein’s local realistic expectations.

MIT’s Quantum Experiment Challenges Einstein’s Classical View

As per Sci Tech Daily, Einstein argued for the deterministic reality, and claimed that the particles must be definite properties irrespective of the observation and that nothing could travel faster than light. With the Copenhagen interpretation, Bohr held the views which posit that only measurement defines the physical reality, along with complementary properties such as wave and particle behaviour, which are exclusive. The result of MIT supports this interpretation by Bohr.

With the removal of spring elements and the intrinsic quantum uncertain reliability of the ultracold atoms, MIT has sidestepped classical interference artefacts. Through this design, the experiment cleanly isolates the quantum effects and makes the result more robust and vague. Their behaviour demonstrates the dual nature when the individual photons pass through this experiment.

Bohr’s Complementarity Confirmed: Nature Obeys Quantum Rules

The findings through this experiment not only give the mechanical predictions and however, but also reinforce the significance of the theorem by Bell. Experiments done by Delft and Aspect have questioned the inequabilities under restricted conditions, strongly discrediting the hidden variable arguments of Einstein.

In a nutshell, MIT’s ultra double-slit experiment provides compelling evidence against the local realism of Einstein but in favour of the indeterminacy of quantum. Through the demonstration of the complementarity of the minimal classical interference, it is clear that the experiment underscores that nature follows the rules of quantum mechanics.

PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued

PSR J0922+0638 is one of the pulsars, which are typically ultradense remains of a massive star that exploded as a supernova. These are quite compact and lie a few miles away; however, they carry more weight than several other suns. Their density infers that the internal matter is packed tightly, and the borders diverge toward the black hole. However, the collapse of these stars is prevented due to the pressure from the quantum forces. Neutrons and protons smash together at the time of extreme densities, and then they create a single gigantic atomic nucleus. However, the core of the neutron stars is still a mystery.

Unraveling the Structure and Rotation of PSR J0922+0638

As per space report, these dense stars act as giant atomic nuclei together with the neutrons and protons pulled together under the gravity. One of the behaviours of pulsars is their rotation, which is stable. For example, PSR J0922+0638 rotates after every 0.43063, and this continues for thousands of years.

Astronomers studied the data from over 22 years to further understand the stability. The data was collected from South Africa’s MeerKAT array and China’s Nanshan Radio Telescope array. Although the changes were minuscule, even less than a billionth, the stars show an energy shift because of the intense physical forces. The scientists found a dozen glitches that we call a little change in the rate of rotation. The glitches followed a cycle in which rotation repeats after every 550 days.

Glitches, Magnetic Cycles, and the Mystery Within Pulsars

Furthermore, due to sudden glitches, a slow and cyclic speeding up and slowing down of the spin of the pulsar was seen during a 500-600-day period. This behaviour made the scientists question the glitches and the time variations of the pulsar, with the unawareness of the exact cause.

The theories put forward by the scientists comprise the magnetic cycle, which is similar to the movement of the superfluid in the star or the sun. Even after these theories, the internal mechanics of a pulsar are speculative. Further, long-term observations are important to know these secrets.
