Crew Escape System

October 15, 2025

Crew Escape System Latest News

ISRO has developed a cost-effective, single-stage Test vehicle powered by the Vikas engine to validate the crew escape system (CES).

About Crew Escape System

It is an emergency escape measure designed to quickly pull the crew module along with the astronauts to a safe distance from the launch vehicle in the event of a launch abort.
The CES is classified into two types based on the way it extracts the crew module:
- Puller type: It is used in Gaganyaan, where the CES pulls the crew module away from the launch vehicle;
- Pusher type: It is used in vehicles like SpaceX’s Falcon 9, where the crew module is pushed away using compact, high-thrust liquid-fuel engines.
The U.S.’s Saturn V, Russia’s Soyuz, and China’s Long March vehicles also use puller-type CES designs.

Working of Crew Escape System

Once the CES has moved the crew module a safe distance away from the failing vehicle, the module will be released and decelerated by a multistage parachute system.
It will reduce the module’s velocity in steps, ensuring it splashes down safely in the sea without exceeding the crew’s physiological limits upon impact.
Typically, the crew will remain inside the module until splashdown.
The Integrated Vehicle Health Management system (IVHM), which is a network of sensors, electronics, and software, will aid in taking a decision to activate the CES when a contingency arises.
- It will monitor all vital parameters of vehicle systems and crew health in real time.
- Based on the synthesised information and the flight regime, it will ensure prompt anomaly detection, minimise false alarms, and activate the CES early enough to protect the crew.

Crew Escape System FAQs

Q1: What is the primary purpose of the Crew Escape System (CES)?

Ans: To ensure the safe escape of astronauts during critical phases of flight.

Q2: During which phase of flight is the Crew Escape System (CES) most crucial?

Ans: Launch phase.

Sudden Infant Death Syndrome

October 15, 2025

Sudden Infant Death Syndrome Latest News

Sudden Infant Death Syndrome (SIDS) is a leading cause of infant mortality globally and October is marked as Sudden Infant Death Syndrome month.

About Sudden Infant Death Syndrome

It is the term used to describe the sudden and unexpected death of an infant that is less than one year old, for which no cause can be found even after an investigation.
It is sometimes known as ‘cot death’ or ‘crib death’, even though cots and cribs are not the cause of these deaths.
The most SIDS deaths occur during the first six months of a baby’s life.
It occurs slightly more in baby boys and happens when the baby is asleep.

Risk Factors for SIDS

Premature birth or low birth weight;
A family history as babies who have had a sibling who died of SIDS are at a higher risk; Exposure to smoking/secondhand smoke during or after pregnancy;
Unsafe sleeping positions or environments and poor prenatal care.

Possible Causes of Sudden Infant Death Syndrome

Problems of under-development of the part of the brain that helps control breathing and waking during sleep.
It may also be a genetic vulnerability or a vulnerability to environmental stresses.
Vaccines do not cause SIDS.

About Fare se Fursat Fixed Airfare Scheme

It is aimed at giving passengers freedom from the stress of fluctuating airfares and promoting ease of flying in the country.
Objective: To address this long-standing challenge by introducing transparency and stability in pricing.
It is an initiative by India’s government-owned regional carrier, Alliance Air which offers a single, fixed fare that remains constant regardless of the booking date, even on the day of departure.
- Alliance Air operates short and medium-route flights, primarily connecting tier 2 and tier 3 cities under the union government’s Ude Desh ka Aam Nagrik (UDAN) scheme.
Pilot Phase: The initiative will be implemented on a pilot basis from October 13 to December 31, 2025 across select routes.
The initiative is also expected to encourage first-time flyers from smaller towns to opt for air travel, and make air travel available, accessible and affordable.
Advantages: The static fare system eliminates uncertainty and stress associated with fluctuating airfares, ensuring predictability of costs, even for last-minute bookings.

Parkinson’s Disease

October 15, 2025

Parkinson's Disease Latest News

A condition that compels people to move their legs could indicate they have a greater chance of developing Parkinson's disease.

About Parkinson's Disease

It is a progressive neurodegenerative disorder that primarily affects movement.
It causes nerve cells (neurons) in parts of the brain to weaken, become damaged, and die, leading to symptoms that include problems with movement, tremor, stiffness, and impaired balance.
As symptoms progress, people with PD may have difficulty walking, talking, or completing other simple tasks.
Although many brain areas are affected in Parkinson’s disease, the most common symptoms result from the loss of neurons in an area near the base of the brain called the substantia nigra.
- The neurons in this area produce dopamine.
- Dopamine is the chemical messenger that transmits signals in the brain to produce smooth, purposeful movement.
- Most people with PD have lost 60 to 80% or more of the dopamine-producing cells in the substantia nigra by the time symptoms appear.
- Lack of dopamine causes the slowed movements and tremors symptoms of Parkinson’s disease.
Who does it affect?
- The disease usually occurs in older people, but younger people can also be affected.
- Men are affected more often than women.
- The cause of PD is unknown but people with a family history of the disease have a higher risk.
- Exposure to air pollution, pesticides, and solvents may increase risk.
- People with PD often develop a “parkinsonian gait.”
  - This includes a tendency to lean forward, taking small, quick steps as if hurrying (called festination), and reduced swinging in one or both arms.
  - They may have trouble initiating movement (called “start hesitation”) and stop suddenly as they walk, freezing in place.
Diagnosis: Currently, no blood laboratory or radiological tests are available to diagnose Parkinson’s disease.
Treatment: There’s no cure for this disease, but treatments can help significantly improve your symptoms.

Ans: Men, particularly older adults.

Q4: What causes the tremors and slow movement in Parkinson’s disease?

Ans: Loss of dopamine-producing neurons

Rhodamine-B

October 15, 2025

Rhodamine B Latest News

Recently, scientists at Raman Research Institute (RRI) have developed a powerful and cost-effective technique that uses the coffee-stain effect to identify harmful dyes such as Rhodamine B.

About Rhodamine B

It is a synthetic dye known for its bright pink colour.
Characteristics:
- It is a water-soluble chemical compound.
- It appears green in powder form; it turns vivid fluorescent pink when it comes in contact with water.

Applications of Rhodamine B

It is commonly used in industries such as textiles, paper, and leather.
Its application extends to scientific research due to its fluorescent properties.

Impacts of Rhodamine B on Human Health

It can cause DNA damage, leading to mutations and potentially triggering cancerous growths.
Animal research has demonstrated tumor development in organs like the liver and bladder following prolonged exposure to the dye.
In sensitive individuals, they can lead to allergic reactions such as itching, redness, and skin thickening.
Long-term exposure to synthetic dyes like Rhodamine B can result in chronic allergic reactions and permanent skin pigmentation changes.
The chemical is toxic for humans and can cause oxidative stress on cells and tissues if ingested.
