Hanle Dark Sky Reserve (HDSR) is India’s 1st dark sky region which was notified by UT of Ladakh comprising an area of radius roughly 22 km around Hanle.

  • Objectives of HDSR– It preserves the dark skies by reducing light pollution in the surrounding areas.
  • It uses these dark skies to promote astrotourism as a means to further enhance socio-economic development in the area.
  • Significance of Dark Sky – To observe stars, star clusters, nebulae, and galaxies (such as Milky Way, Andromeda and the Triangulum) with the naked eye.

Bortle Scale

  • It helps to measure the night sky’s brightness at a given location.
  • It scale ranges from Class 1 (darkest skies available over the earth) to Class 9 (pale, light-marred skies over the insides of cities).
  • HDSR comes under Bortle Class 1 skies.

Optical phenomenon in the sky

  • Zodiacal light – A faint glow of diffuse sunlight scattered by interplanetary dust in the Solar System.
  • Airglow – An optical phenomenon caused by faint emission of light in the earth’s atmosphere.
  • Gegenschein – It is also known as counterglow, which is a bright spot in the night sky centred at the antisolar point, caused due to backscatter of sunlight by interplanetary dust.

SIM Card

SIM cards are the ID cards of the cellular world, and they have evolved in step with cellular networks.

  • SIM – It stands for ‘subscriber identification module’.
  • It is an integrated circuit (IC), or a microchip, that identifies the subscriber on a given network.

German engineer Helmut Gröttrup 1st had the idea to stick an IC in a plastic panel in the late 1960s which was basis of origin of the SIM card.

Partsofsimcard

  • Design – In accordance with ISO/IEC 7816 international standard.
  • Sizes – They are available in standard, micro and nano sizes.
  • Types
    • GSM SIM (Global System for Mobiles) – It can be removed and inserted in any mobile cell phone.
    • CDMA SIM (Code Division Multiple Access) – It cannot be removed from the original Phone.
    • eSIM Card (Embedded SIM) – It is a small chip pre-assembled inside the phone that enables easier swap of network operator as the information on eSIM is re-writable.

Until 2G networks, SIM card comprised both the hardware and the corresponding software. With the advent of 3G networks, it became only the software while the hardware was called the Universal Integrated Circuit Card (UICC).

Functions of SIM card

  • SIM card has a unique authentication key which when unlocked, allows access to the network.
  • Any signals sent by the phone into the network are ‘signed’ by the key.
  • Connects mobiles to cellular networkWhen a subscriber dials a recipient’s number, the phone sends data via the network signed by the key on the SIM card to a telephone exchange.
  • Storage function of SIM Card
    • Own ID number (the integrated circuit card identifier)
    • The International Mobile Subscriber Identity (IMSI)
    • The subscriber’s location area identity
    • A list of preferred networks
    • Emergency numbers
    • The subscriber’s contacts and SMS messages.
  • Challenges – It is possible to duplicate a SIM card by accessing its key and storing it in multiple cards.
