  2. During same event, ISRO displayed a space suit developed for Gaganyaan Mission 2022. It is an orange-coloured prototype space suit developed at Vikram Sarabhai Space Centre in Thiruvananthapuram. It can hold one oxygen cylinder, allowing an astronaut to breathe in space for 60 minutes.
  3. ISRO also displayed a crew model and crew escape model, with thermal shield and temperature inside maintained at 25 degree Celsius.
  4. Gaganyaan Mission astranauts will be living for five to seven days in a 400-km orbit from the Earth’s surface as they would conduct micro-gravity experiments.
  5. Theme for Bengaluru Space Expo 2018 was Creating dynamism in Indian space ecosystem.
None of These

8. Indian Space Research Organisation (ISRO) successfully launched its PSLV-C42 rocket carrying two ___________________ Earth observation satellites - NovaSAR and S1-4, intended to improve disaster management capabilities.

None of These

9. India’s Mars mission Mangalyaan, successfully completed four years around Mars, despite being designed to last only six months. ISRO inserted Mangalyaan into Mars’ orbit in its first attempt on ____________________, 2014.

  1. Also, ASTROSAT, India’s first multi-wavelength space observatory will complete 3 years in Earth’s orbit (Launched on September 28, 2015). ASTROSAT has helped scientists confirm the presence of younger stars in globular clusters, earlier believed to contain only old stars.

10. India’s biggest cyclotron facility named Cyclone-30 became operational at Department of Atomic Energy (DAE)'s _____________________-based Variable Energy Cyclotron Centre (VECC).

  1. Cyclotron is used to produce radioisotopes for diagnostic and therapeutic use for cancer care. Radiations from these isotopes are used to destroy cancer cells.
  2. Cyclone-30 will produce radioisotopes vital for diagnosis and treatment of cancer. It will be only cyclotron facility in country to produce Germanium 68 radioisotopes, used in diagnosis of breast cancer.
  3. It will also produce Palladium 103 isotopes, which is used for the treatment of prostate cancer. In its future stages, it will also produce Iodine 123 isotopes, which can help detect thyroid cancer.
None of These

11. India’s first underwater robotic drone –__________________ handed over to Naval Physical and Oceanographic Laboratory (NPOL) of DRDO, as first commercial Remotely Operated Vehicle (ROV) / underwater drone. It would be used by NPOL for research and development activities for defence purposes.

12. Institute of Nuclear Medicine and Allied Sciences (INMAS) developed India’s first indigenous medical kit for protection against nuclear warfare or radioactive leakage. It has ___________________________ items which include radioactive protectors which can absorb 80-90% of radiation, nerve gas agents, bandages that absorb radiation as well as tablets and ointments. Its important parts are -

  1. Prussian blue tablet - Highly effective in incorporating Radio Cesium (Cs-137) and Radio Thallium, among most feared radioisotopes in nuclear bombs that destroy human body cells.
