He has been working for improving the lives of children, especially those who are amongst the most marginalized. Djokovic’s commitment to children’s issues let UNICEF invited him to become a Goodwill Ambassador. He already made a many positive difference in the lives of many children.

On 26 August 2015 , Djokovic has joined other accomplished and commited UNICEF Goodwill Ambassadors including Danny Kaye,Harry Belafonte, Orlando Bloom, Audrey Hepburn,  Harry Belafonte, Orlando Bloom, Katy Perry,David Beckham, Sir Roger Moore, Shakira, Maxim Vengerov, Serena Williams and others.

On 26 August 2015 , Djokovic Novak also signed a Memorandum of Understanding between the World Bank and the Novak Djokovic Foundation to promote early childhood development. United Nations Children’s Fund (UNICEF) and the Novak Djokovic Foundation have established a cooperation on bringing early childhood services  to every child and familiy in Serbia

He is one of the most dominant players to ever set foot on a tennis court. To date, Djokovic has won a total of 54 career titles, including 9 Grand Slams, and he was a Medallist at the 2008 Summer Olympics in Beijing.

Novak Djokovic's contributions to UNICEF



Since he was appointed a UNICEF Serbia Ambassador , he has been helping UNICEF provide quality early care and development to most vulnerable childrens . He has been lending his support to improving the lives of children, with a particular focus on early childhood education and development in providing children with the best start to life.Novak has made a positive difference in the lives of many children, not only as a powerful role model but also as a strong advocate for their rights. 

He as a UNICEF Serbia Ambassador has visited preschools and kindergartens in Serbia to investing in learning at an early age. He and his Novak Djokovic Foundation has helped create more flexible and  high quality  pre-school education programmes for some of Serbia’s most vulnerable children.The Novak Djokovic Foundation also funded UNICEF Serbia’s innovative family outreach service aimed at connecting with families living in urban areas, which was so successful. UNICEF Serbia’s innovative family outreach service has now been integrated into the Serbian child protection system. 

During the floods in the Balkans in 2014, Novak made donations to UNICEF to help with the emergency aid efforts.He and UNIQLO together supported the Schools for Asia initiative in Bangladesh, China and the Philippines as poverty reduction projects in Serbia.

Geosynchronous Satellite Launch Vehicle (GSLV)-D6 was successfully launched from the Second Launch Pad at the Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota in Andhra Pradesh. GSLV-D6 launched GSAT-6 , an advanced communication satellite into a Geosynchronous Transfer Orbit (GTO). The satellite is aimed to provide S-band communication services in the country.This was the second successful flight of the GSLV using the indigenous cryogenic engine.

About GSLV or GSLV-D6



  • GSLV  is an advanced launch vehicle that can be used to carry satellites heavier than 2000-kg.
  • GSLV  is designed to inject 2 ton class of communication satellites into Geosynchronous Transfer Orbit (GTO).
  • GSLV-D6 is the ninth flight of India's Geosynchronous Satellite Launch Vehicle (GSLV). 
  • GSLV-D6 is also the fifth developmental flight of GSLV.
  • GSLV  has made 28 successful launches.GSLV-D5 successfully placed GSAT-14 satellite in January 2014
  • GSLV-D6 is three-stage heavy weight rocket with indigenously made Cryogenic Upper Stage (CUS).
  • GSLV-D6 has a diameter and length 3.4 m and 49.1 m .
  • GSLV-D6 has a lift-off mass of 416 t.

About Cryogenic Upper Stage



  • This is the third time the indigenously developed Cryogenic Upper Stage (CUS) is being carried on-board during a GSLV flight.
  • A Cryogenic rocket stage compared to solid is more efficient and provides more thrust for every kilogram of propellant it burns compared to solid and earth-storable liquid propellant rocket stages.
  • The cryogenic stage is technically a very complex system compared to solid or earth-storable liquid propellant stages due to its use of propellants at extremely low temperatures and the associated thermal and structural challenges.
  • The propellants at  low temperatures , Oxygen liquifies at -183 deg C and Hydrogen at -253 deg C , are to be pumped using turbo pumps running at around 40,000 rpm.
  • The three engines of Cryogenic Upper Stage (CUS) together develop a nominal thrust of 73.55 kN in vacuum.
  • During the flight, Cryogenic Upper Stage (CUS) fires for a nominal duration of 720 seconds.
  • This was the second successful flight of the GSLV using the indigenous cryogenic engine.

About GSAT-6 satellite



  • The GSAT or Geosynchronous satellite is a communication satellites developed by the Indian Space Research Organisation (ISRO) to make India self-reliant in broadcasting services. 
  • The GSAT-6 has a six-metre wide unfurlable antenna.
  • The GSAT-6 has a weight 2117 kg
  • The GSAT-6 function in a geosynchronous orbit around the Earth.
  • The GSAT-1 was launched in April 2001.
  • The GSAT-6 satellite was carrying S-Band and C- Band transponders meant for providing S-band communication services in the country.
