USS Gerald Ford is first in the series of three of the futuristic ships of the Ford-class carriers ordered by US Navy.

Hydroponics is a subset of hydroculture, which is the growing of plants in a soil less medium, or an aquatic based environment. Hydroponic growing uses mineral nutrient solutions to feed the plants in water, without soil.

Both statements are correct. ISRO and NASA are jointly working on the NASA-ISRO Synthetic Aperture Radar (NISAR) mission to co-develop and launch a dual frequency synthetic aperture radar (SAR) satellite by 2021.

The satellite will be the world’s most expensive earth-imaging satellite till date It will be the first radar imaging satellite to use dual frequency.

It will provide an unprecedented detailed view of Earth by taking snapshots every week using advanced radar imaging.

It will be used also for natural resources mapping & monitoring, estimating agricultural biomass over full duration of crop cycle.

Antibiotics are medicines used to treat infections caused by bacteria. Antibiotics don’t work against infections caused by viruses, such as colds and flu.

H1N1 flu is also known as swine flu. It’s called swine flu because in the past, the people who caught it had direct contact with pigs.

Statement 1 is correct. GSLV Mk III is a three-stage heavy lift launch vehicle developed by ISRO. GSLV Mk III is designed to carry 4 ton class of satellites into Geosynchronous Transfer Orbit (GTO) or about 10 tons to Low Earth Orbit (LEO), which is about twice the capability of GSLV Mk II.

Statement 2 is incorrect. It consists of 3 stages. First stage will have a solid propellant, second stage will have liquid propellant and third stage will be a cryogenic engine.

More than 5 decades of human space exploration since the first Soviet-launched Sputnik satellite in 1957 has produced this hazardous belt of orbiting debris in the space. There are estimated to be more than 100 million pieces are circling our planet in the lower orbit, posing a growing threat to future space exploration. These pieces of debris travel at high speeds. A relatively small piece of orbital debris can inflict a great deal of damage on satellites or spacecrafts orbiting in the space. This phenomenon is Kessler Syndrome which describes a self-sustaining cascading collision of space debris in low earth Orbit.
