A spacecraft named Hera has successfully launched from Cape Canaveral, Florida, on a mission to study the asteroid Dimorphos, which was intentionally redirected by NASA in 2022. The launch took place at 10:52 local time (15:52 BST) on Monday, marking a significant step in international efforts to explore how we can prevent potential asteroid threats to Earth. The Hera mission, led by the European Space Agency (ESA), aims to gather vital data about Dimorphos, located approximately seven million miles away, with an expected arrival in December 2026.

Understanding Asteroid Redirection

Dimorphos is a small moon with a diameter of 160 metres that orbits a larger asteroid, Didymos. The DART (Double Asteroid Redirection Test) mission by NASA successfully altered Dimorphos’s trajectory in a groundbreaking test. According to NASA scientists, the collision with the spacecraft shifted the asteroid’s course by a few metres. Although Dimorphos was not on a collision course with Earth, the experiment demonstrated that asteroid redirection is feasible, providing critical insights into how we might tackle real threats in the future.

Objectives of the Hera Mission

Upon reaching Dimorphos, the Hera spacecraft will conduct an in-depth examination of the impact crater created by the DART collision. Additionally, it will deploy two cube-shaped probes designed to analyse the asteroid’s composition and mass. Dr Naomi Murdoch, a scientist at the European Space Agency, emphasised the importance of understanding the physical properties of asteroids, such as their composition, to enhance future deflection strategies.

The Importance of Asteroid Research

While there is currently no significant threat of a massive asteroid impact akin to the extinction event that wiped out the dinosaurs, smaller asteroids can and do collide with Earth. A notable incident occurred in 2013, when a house-sized asteroid exploded over Chelyabinsk, Russia, injuring over 1,600 people. This highlights the necessity for ongoing research into asteroid detection and redirection methods.

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.
