Five Generations of Launch Vehicles Developed by ISRO

ISRO has developed five generations of launch vehicles for space missions. Here are their names:

1. SLV (Satellite Launch Vehicle)

• First generation, capable of launching small payloads into low Earth orbit.

2. ASLV (Augmented Satellite Launch Vehicle)

• An improvement over SLV, designed to launch heavier payloads.

3. PSLV (Polar Satellite Launch Vehicle)

• One of the most successful, used for launching satellites into polar orbits.

4. GSLV (Geosynchronous Satellite Launch Vehicle)

• Used for launching heavier payloads into geosynchronous orbits.

5. GSLV Mk III

• The most advanced, capable of launching heavier payloads, including the Chandrayaan-2 mission.

Summary: ISRO’s launch vehicles, from SLV to GSLV Mk III, have evolved to support various space exploration and satellite missions.

The Causative Agent of Dengue Fever

The causative agent of Dengue fever is the Dengue virus, which is transmitted through the bite of Aedes mosquitoes.

How Dengue Spreads

• Aedes mosquitoes (especially Aedes aegypti) carry the virus and bite humans to transmit it.
• The virus causes flu-like symptoms like fever, joint pain, and skin rashes.

Example

• Aedes mosquitoes breed in stagnant water, like in flower pots or uncovered containers.

Summary: Dengue fever is caused by the Dengue virus, transmitted by Aedes mosquitoes, which bite during the day.
