21. What is the name of the nuclear fusion-powered rocket developed by Pulsar Fusion, a British startup, to revolutionize interplanetary travel?
[A] Dragonfly
[B] Starship
[C] Sunbird
[D] Juno
Show Answer
Correct Answer: C [Sunbird]
Notes:
Sunbird is a nuclear fusion-powered rocket developed by Pulsar Fusion, a British startup, to transform interplanetary travel with much faster speeds. It could reach up to 805,000 km/h, surpassing the current fastest object, NASA’s Parker Solar Probe, which travels at 692,000 km/h. With this speed, Sunbird could reduce travel time to Mars by almost half and reach Pluto in just 4 years. A major orbital test is planned in 2027, showing progress in next-generation space propulsion. Nuclear fusion, which powers Sunbird, fuses atoms like stars do, giving high energy with minimal radioactive waste, unlike nuclear fission.

[A] NITI Aayog
[B] Cotton Corporation of India (CCI)
[C] IIT Delhi
[D] Ministry of Commerce and Industry
Show Answer
Correct Answer: A [NITI Aayog]
Notes:
NITI Aayog released a report titled ‘Unlocking 25+ Billion Export Potential – India’s Hand & Power Tools Sector’. It highlights how the Hand and Power Tools sector can boost India’s economic growth. The global market for these tools is valued at 100 billion and may grow to 190 billion by 2035. India exports only 600 million in hand tools and 470 million in power tools, with very low market shares. The report suggests India can target 25 billion in exports and generate 35 lakh jobs by gaining 10% in power tools and 25% in hand tools. India can achieve this by encouraging innovation, supporting Micro, Small and Medium Enterprises (MSMEs), and improving industrial infrastructure. The tools sector is a pillar of global manufacturing and can support India’s goal of becoming Viksit Bharat @ 2047. Growth in construction and Do-It-Yourself (DIY) markets can boost Make in India and expand India’s global footprint by $25 billion.
