Mars in three days

• Tip to Mars = 600 trips from Earth to moon.

• Trip to mars = 73791+ trips from Jammu to Kanyakumari.

• Fastest satellite ever sent is New Horizon, will take 162 days, if we use it to send to Mars.

2

Chemical Propulsion

• NASA and other space agencies uses chemical propulsion.

• It requires burning of liquid

Hydrogen and Oxygen.

3

A new technology : Solar Sail

4

Design: Normal Wind Sail

5

6

IKAROS

• Japanese Satellite• Launched in 2010• To measure thrust force by

the solar radiation pressure.

7

Limitations of Solar Sails

• Light from the sun gets weaker the farther away it travels.

• So we need larger sails to move at higher speed, practically difficult to achieve.

8

DE-STAR• Directed Energy System

for Targeting of Asteroids and Exploration

• Used to deflect Asteroid from it’s path coming towards Earth.

Wafer Sats : Miniature Spacecrafts

10

Photonic Propulsion

• Concentrated laser beam focused at the spacecraft.

• Using this technology we can reach up to 25% of the speed of light.

11

Method 1 : Ground Lasers

12

Method 2 : Space Lasers

• A Giant set of lasers , set up in space.

• It takes power from Sun , using solar panels and then transmit that power towards space-craft in form of laser.

13

Interstellar Travel

• Voyager 1, launched in 1977, will take 40,000yr to reach proxima centauri.

• Using this technology we can sent miniature satellite in just 17yr.

• One day this can also be used to send humans to other stars.

15

Voyager 1 is just 0.05% of it’s Journey to Alpha Centauri

14

Breakthrough Starshot

• Yuri Miller – Billionaire , Investor.• Stephen Hawking – One of the

Greatest Scientist of Modern Time.

• Yuri Miller to Invest $ 100 Million.

• Facebook Founder Mark Zuckerberg has also shown interest.
