    BepiColombo Mission

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: BepiColombo Mission

    BepiColombo

    Why in the News?

    • On Thursday, the ESA-Japan spacecraft “BepiColombo” made its closest approach to Mercury, capturing detailed images of its sunrise-lit surface and revealing the planet’s south pole.

    Highlights of the Latest Flyby:

      • BepiColombo uses flybys of Earth, Venus, and Mercury to slow down and enter orbit around Mercury. This approach gives scientists new information about Mercury’s south pole and its unusual peak ring craters, which haven’t been studied much before.

      Note: Flybys are close passes of a spacecraft near a planet or celestial body

    What is Helium and why is it used in Rockets?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Helium

    Why in the News?

    Two NASA astronauts aboard Boeing’s Starliner will remain on the International Space Station (ISS) for an extended period due to issues with a faulty propulsion system, including helium leaks.

    helium

    About Helium

    • Helium is inert, meaning it does not react or combust when exposed to other substances.
    • This makes it ideal for pressurization and cooling systems in rockets and spacecraft.
    • With an atomic number of 2, Helium is second lightest element after hydrogen, helping to keep the rocket’s weight low, which is crucial for achieving the necessary speeds and altitudes to reach orbit.
    • It has an extremely low boiling point (-268.9°C), allowing it to stay in a gaseous state in super-cold environments, where many rocket fuels are stored.
    • Though non-toxic, helium cannot be inhaled on its own as it displaces oxygen, which is vital for human respiration.

    How is Helium used for space applications?

    • Fuel Tank Pressurization: Helium pressurizes fuel tanks, ensuring a consistent flow of fuel to the rocket’s engines, even as the fuel is burned.
    • Cooling Systems: It also plays a key role in cooling systems, particularly in environments where rocket fuel and oxidizer need to be stored at extremely low temperatures.
    • Maintaining Tank Pressure: As fuel and oxidizer are consumed, helium fills the empty space left behind, ensuring the overall pressure inside the tanks remains stable.

    Is Helium prone to leaks?

    • Helium’s small atomic size and low molecular weight make it prone to leaking through tiny gaps or seals in storage tanks and fuel systems.
    • Since helium is rare in Earth’s atmosphere, even minor leaks are easily detectable, making it a valuable tool for spotting potential faults in spacecraft fuel systems.
    • Examples of Leaks:
      • In May, hours before Boeing’s Starliner spacecraft attempted its first astronaut launch, sensors detected a small helium leak in one of its thrusters.
      • After Starliner launched in June, additional leaks were found in space, prompting NASA to return the spacecraft to Earth without its crew.

    Alternatives to Helium

    • Argon and Nitrogen: Some rocket launches have experimented with other inert gases like argon and nitrogen, which are sometimes cheaper, but helium remains the industry standard.
    • Ariane 6’s Novel System: Europe’s new Ariane 6 rocket abandoned helium in favor of a pressurization system that converts small amounts of its liquid oxygen and hydrogen into gas for pressurizing the fuel.
      • However, during Ariane 6’s debut launch, this system failed in space, adding to the global rocket industry’s pressurization challenges.

    PYQ:

    [2012] A team of scientists at Brookhaven National Laboratory included those from India created the heaviest anti-matter (anti-helium nucleus). What is/are the implication/implications of the creation of anti-matter?

    What is the Principle of Planetary Protection?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Principle of Planetary Protection

    Why in the News?

    • Planetary protection is a crucial principle in space missions that travel from Earth to other planetary bodies, such as the Moon or Mars.
      • The goal is to preserve both Earth’s biosphere and the planetary body’s environment from contamination by alien microbial life.

    About Planetary Protection:

    Details
    Definition Safeguarding Earth’s biosphere and other planetary bodies from microbial contamination during space missions.
    Objective Prevent contamination of Earth’s environment and other planets by alien microbes or Earth-origin microorganisms.
    Legal Basis Article IX of Outer Space Treaty (1967) mandates avoiding harmful contamination in space exploration.
    Importance
    • Protects integrity of scientific research on other planets.
    • Prevents potential biological threats to Earth.
    Methods of Implementation
    • Spacecraft sterilization (e.g. baking in a dry room at 120°C for 3 days).
    • Planning missions to avoid cross-contamination.
    Key Applications Missions to Mars, Moon, Europa and other celestial bodies where contamination may disrupt research or pose risks.
    Challenges Increased costs and technical demands for maintaining sterile spacecraft and environments.
    Recent Example China’s Tianwen-3 Mars sample-return mission (2028) confirmed adherence to planetary protection principles.
    Global Cooperation International space agencies follow planetary protection guidelines for sustainable and safe space exploration.

    Yellow Food Dye can improve Cancer Treatment

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Yellow Food Dye

    Why in the News?

    Recent research reveals that FD&C Yellow 5, a common food dye, can temporarily make tissue transparent, with potential implications for cancer treatment and medical procedures.

    About Yellow Food Dye 

    • FD&C Yellow 5, also known as Tartrazine, is a widely used synthetic food dye found in various snacks, drinks, and processed foods.
    • Approved by the FDA, it is commonly used to give products a vibrant yellow color.

    How does it work?

    • The dye has the ability to make tissue transparent is based on its interaction with light, specifically through the Kramers-Kronig relations, a principle in physics.
    • It absorbs blue light, leaving only the red-orange spectrum visible.
    • This alters the refractive index of water, causing it to match the refractive index of fats and proteins in tissue.
    • When the refractive indices match, light can pass through tissue with less scattering, creating the appearance of transparency.

    Potential Medical Applications of Yellow Food Dye

    • Cancer Treatment: By making tissues transparent, FD&C Yellow 5 could enhance photodynamic and photothermal therapies, allowing laser light to reach deeper tissues and target cancerous cells more effectively.
    • Vein Visibility: Transparent tissues could help make veins more visible, aiding in procedures like venepuncture for blood draws or injections, particularly in patients with hard-to-see veins.
    • Non-invasive Diagnostics: The dye could allow doctors to visualize internal organs and structures without the need for invasive procedures like biopsies or expensive imaging technologies like CT scans or MRIs.

    PYQ:

    [2018] Consider the following statements:

    1. The Food Safety and Standards Act, 2006 replaced the Prevention of Food Adulteration Act, 1954.

    2. The Food Safety and Standards Authority of India (FSSAI) is under the charge of Director General of Health Services in the Union Ministry of Health and Family Welfare.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 only

    (c) Both 1 and 2

    (d) Neither 1 nor 2
