Let’s Understand in simple way about each topic:

What is Gaganyaan Mission.: Gaganyaan, as the name suggests is a Space mission Of ISRO, But in this ISRO is planning to send three people to space. It is a 10,000 crore project which was originally aimed to be completed by 2022 on the 75th anniversary of India’s Independence. But the pandemic situation has delayed this project, and its estimated that the mission wont take off until 2023. ISRO is planning the spacecraft to be in space for 5 -7 days and return to earth safely. PM Modi had announced the launching of Gaganyaan during his 2018 Republic day Speech. (the above info. is enough for you to write the introduction in your mains answer when asked about Gaganyaan, no need to search further.)
Whats the Need of Gaganyaan Mission?: India has shown to the world and have proven its strength of producing and launching missions to the planet Mars and also moon in a very economic way using it’s PSLV and GSLV technologies. (You should keep one thing in mind, we developed our own GSLV methodology. We wanted this technology from the 1990’s itself, but USA feared that India will join the space race and hence did not give us the technology,also India’s Nuclear mission created fear in Uncle Sam. We then asked for Russia’s help, but even Russia did not help us with the technology, but only provided us the engines. Our scentists disembodied the engines, studied its working and then created the Launch Vehicle technology.) And now India has understood that to keep up with the global space race and to secure it’s strategic position, it needs to create an indigenous mission to explore the infinite cosmos. Also Russia and USA leading in the Space missions and China rapidly making its way up, gives a sense of urgency to Indian Scientists. You may have a question as to what is the use of such space projects? You see when you explore and make study about the cosmos and life in other planets or any other topic from its vast array, you help the country, the scientists, the climate experts etc in their quest of understanding the happenings and history of space. This ultimately helps the Indian Govt. to give accurate data about the climate and helps in making future predictions related to space. Moreover, India’s cost effective launch technologies is a hit among the nations. India, infact is now in the position to launch several payloads and satellites of foreign countries while deploying its own. This has helped Newspace India Limited, ISRO’s commercial arm to get Forex by sending satellites of other countries.

About Vikas Engine: (Just read this section, it is not that important for Mains or pre): VIKAS Engine is the abbreviation of VIKram Ambalal Sarabhai and is from a family of liquid-fueled rocket engines. It is used in both GSLV and PSLV launch vehicles. It basically used to power the second stage in PSLV, GSLV MK I and GSLV MK II, and the core stage of GSLV MK III
