Lagrange Points

Context: The Indian Space Research Organisation (ISRO)’s Aditya-L1 spacecraft has escaped the sphere of Earth’s influence, and is currently on its way to reach the Sun-Earth Lagrange Point 1 (L1).

What are Lagrange Points?

  • Lagrange points are positions in space where the gravitational forces of two massive orbiting bodies, such as the Sun and Earth, balance each other.
  • This allows a small object, such as a spacecraft, to remain in a relatively stable orbit with minimal fuel consumption, which can be especially important for long-duration missions.
  • There are five Lagrange points in the Sun-Earth system, labeled L1 through L5:
  • Located between the Sun and Earth, slightly closer to the Sun.
  • It is about 1.5 million km from the Earth.
  • Good location for spacecraft that need to observe the Sun,
  • L1 point is home to the Solar and Heliospheric Observatory Satellite (SOHO).
    • SOHO is the collaboration project of NASA and the European Space Agency.
  • Located behind the Earth, opposite the Sun.
  • Good location for spacecraft that need to observe the far side of the Sun.
  • L2 point is home to the James Webb Space Telescope (JWST).
    • JWST is collaboration among NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
  • Located even further behind the Earth, beyond the orbit of the Moon.
  • It is a more difficult location to reach, but it offers a good vantage point for observing the entire Earth-Moon system.
L4 and L5
  • L4 and L5 are located at the two vertices of an equilateral triangle, with the Sun and Earth at the other two vertices.
  • L4 and L5 are good locations for spacecraft that need to remain in a relatively fixed position relative to the Earth, such as communication satellites.

About the Aditya L1 Mission

  • Aditya L1 is the first space based Indian mission to study the Sun.
  • Objective: To study Sun’s atmosphere and magnetic field.
  • Key Payloads of the Aditya L1 Spacecraft:
    • Visible Emission Line Coronagraph (VELC): to study the dynamics of the solar corona.
    • Solar Ultraviolet Imaging Telescope (SUIT): to image the Sun in the ultraviolet wavelength range.
    • Solar Low Energy X-ray Spectrometer (SoLEXS): to measure the X-ray spectrum of the Sun.
    • High Energy L1 Orbiting X-ray Spectrometer (HEL1OS): to measure the X-ray spectrum of the Sun in the high-energy range.

Context: Recently, the oil companies raised the prices of commercial LPG and aviation turbine fuel (ATF).

More on News

  • Increase in prices of commercial LPG: ₹209 per 19-kg cylinder.
  • Increase in prices of ATF: 5%

Liquefied Petroleum Gas (LPG)

  • Definition:
    • Like all fossil fuels, it is a non-renewable source of energy.
    • It is extracted from crude oil and natural gas.
    • LPG is composed hydrocarbons. The normal components of LPG are propane and butane.
  • Properties of LPG:
    • Stored in a liquefied state, 1 liter of LPG is as efficient as 270 liters of gaseous energy (natural gas).
    • Colourless
    • Highly flammable
    • High caloric value, i.e. it is a good energy source as it provides a high level of heat.
    • Has almost no sulphur content, which results in cleaner burning.
  • Use:
    • Fuel for cooking and heating in place of natural gas.
    • It is also used as propellant in refrigerators.
    • Alternative fuel: LPG is a cleaner energy source than petrol: its CO2 emission rate is 10% lower.
    • LPG is much cheaper than petrol or diesel.
  • LPG in India:
    • PMUY:
      • The Union Government had approved 75 lakh new LPG connections under the Prime Minister’s Ujjwala Yojana recently with an aim to provide these connections over the next 3 years at an estimated cost of ₹1,650 crore.
    • Use:
      • More than 70% of Indian households use LPG as their primary cooking fuel and nearly 85% have LPG connections.
    • Problems:
      • 15% of Indian households still lack LPG connections.

    • Airlines must either absorb the price volatility or pass the same to consumers.
    • However, globalization and the competitive scenario existent today demands competitive pricing in the absence of which airlines stand to lose business.


Cytrox’s Predator Spyware

Context: Cytrox’s Predator spyware has been reported to have been used to target the iPhone belonging to a former Egyptian Member of Parliament.

Cytrox’s Predator Spyware

  • Definition: Predator spyware is developed by a company called Cytrox which is headquartered in Skopje, North Macedonia.
  • Use:
    • It is capable of recording audio, adding CA certificates, and even hiding apps.
      • A certificate authority (CA) is a trusted organization that issues digital certificates for websites and other entities. CAs validate a website domain.
    • It was used by government-backed threat actors in Egypt, Armenia, Greece and Indonesia to spy on political rivals, journalists and critics of their respective government.
    • Attackers can use this spyware to track one’s online activities across the web and build a profile on them.
  • Working:
    • Victims are receiving a message in emails that comes attached with a one-time link that imitates a URL shortener service.
    • Victims are being redirected to a domain owned by the attacker once they click on the link.
    •  This domain will deliver a simple Android malware called ALIEN before redirecting their browser to a legitimate website.
    • The Alien Android malware is responsible for loading the Predator spyware which first infected the targeted Android devices.
    • Alien receives commands from Predator which allow the spyware to record audio, add CA certificates and even hide apps on a user’s device.
  • Solution: Tech giants including Meta, Google, and Apple have taken concrete steps to address the problem of commercial spyware firms exploiting bugs in their software.
    • Apple has released a ‘Lockdown Mode’, which has “extreme protection” designed for high-risk individuals.
    • While the Lockdown Mode in Apple’s software limits the device’s functionality, it has proven to be a viable option to protect against spyware attacks.


  • Definition: Spyware is a malicious software designed to enter a device, gather sensitive data, and forward it to a third party without the user’s consent.
    • While spyware is used for commercial purposes like advertising, malicious spyware is used to profit from data stolen from a victim’s device.
    • Israel is the leading exporter of spyware and digital forensics.
  • Types:
    • Trojan Spyware: Is a malicious software that appears legal yet can take control of one’s device. A Trojan is a computer program designed to hurt, disrupt, steal, or otherwise harm one’s information or network.

    • System Monitors: Software programs that track one’s activity and enable hackers to gain access to their private information.

Commercial Spyware

  • Definition: Commercial spyware mainly targets mobile platforms and can legitimately be used against criminals and terrorists.
  • Enhanced Use:
    • Earlier spywares were limited to being used by criminals to steal passwords or financial information.
    • Due to the lack of global regulations for companies developing spyware has led to their use by authoritarian governments to spy on political opponents.
    • Example: Commercial spyware like Pegasus spyware can not only extract information from mobile devices but also turn on the camera and microphone without the owner’s knowledge, effectively turning handsets into a spying device.
    • The software allows operators to gain remote access to devices so they can target individuals from almost any part of the world.
    • Spyware is also a tool of intimidation for journalists, activists, and opposition politicians.
    • As per Carnegie Endowment for International Peace, 44 countries have procured targeted surveillance technologies.



Context: The 22nd Law Commission of India has given several recommendations related to the electronic first information reports (e-FIR).

What is an e-FIR?

  • An e-FIR, or electronic First Information Report, is an online version of a First Information Report.
    • First Information Report (FIR) is a written document prepared by the police when they receive information about the commission of a cognizable offence.
    • The term FIR is not defined in the Indian Penal Code (IPC), Code of Criminal Procedure (CrPC), 1973, or in any other law.
    • However, in police regulations or rules, information recorded under Section 154 of CrPC is known as First Information Report (FIR).

Advantages of e-FIR

  • Convenience: e-FIRs can be filed from anywhere with an internet connection, 24/7.
  • Speed: e-FIRs are registered immediately i.e., the police can begin their investigation sooner.
  • Accuracy: e-FIRs are less likely to contain errors than traditional FIRs, which are handwritten and often difficult to decipher.
  • Transparency and Accountability: e-FIRs are available online for the public to view.

Recommendations by the Law Commission

  • Expanding the scope of e-FIRs: Currently, e-FIRs are implemented in eight states but are limited to specific crimes. The commission recommends allowing the filing of e-FIRs for
    • all cognizable offences where the accused is unknown, and
    • all cognizable offences with a jail term of up to three years where the accused is known.
  • Amendments: The commission has recommended suitable amendments to the Code of Criminal Procedure, 1973, Indian Evidence Act, 1872, the Information Technology Act, 2000, the Indian Penal Code,1860 and other legislation to support e-FIR registration.
  • Prevention of false complaints: To prevent false e-FIRs and complaints, the commission suggests verifying the complainant through e-authentication techniques such as OTP verification and mandatory uploading of valid government-approved IDs.
    • The commission also recommends imposing a minimum punishment, including imprisonment and fines, for false registration of e-complaints or e-FIRs.
  • Exemptions: The commission recommended against allowing registration of e-FIR in all cases.
    • It referred to the Supreme Court’s landmark verdict in Lalita Kumari v. State of Uttar Pradesh, in which the court held that preliminary enquiry should be conducted in cases pertaining to matrimonial disputes, commercial offences, medical negligence and corruption, among others.
