World’s Smallest 3-D Printed KalamSat Satellite launched NASA
KalamSat Satellite was launched by NASA - On June 21, 2017 Thursday at around 3 pm. NASA (National Aeronautics and Space Administration) has launched successfully the world’s lightest and smallest satellite from Wallops Island. The smallest 3-D printed satellite was designed mainly by 18 years old Rifath Sharook along with other team mates from India. The satellite named as Kalam SAT, is eponymous with the late president and scientist Dr. APJ Abdul Kalam. The weight of Kalamsat is just 64grams. NASA sounding rocket carried the 64 gram Kalamsat satellite. Total flight time of sounding rocket was 240 minute; Kalamsat got seprated from the rocket 125 minutes after its take-off.
A.P.J. Abdul Kalam Quotes:
“All Birds find shelter during rain. But Eagle avoids rain by flying above clouds.”
- A. P. J. Abdul Kalam
“Don’t take rest after your first victory because if you fail in second, more lips are waiting to say that your first victory was just luck.”
- A. P. J. Abdul Kalam
Kalamsat is a 3.8cm cube and it is lighter than smartphone. Kalamsat was made with fully 3-D printed reinforced carbon fiber polymer. It was equipped with nano Geiger Muller counters for measuring the radiation in space.
Purpose Of Kalamsat:
Kalamsat is a 3-D printed satellite. 3-D printing technology is being used in space for the first time. The main purpose of this small satellite is to find how 3-D printed carbon fiber reinforced polymer works under microgravity environment in space.
What Is Microgravity?
Microgravity means objects or people becoming visibly weightless. Micro means small, gravity means attractive force, microgravity refers extremely less gravity. Under the effect of microgravity objects and astronauts float in space and it is easy to move heavy objects.
Is There Gravity In Space?
Small amount of gravity is found in space; gravity keeps the sun in its place in the Milky Way galaxy, makes the Earth to orbit the sun and holds moon in its orbit around the earth. Gravity becomes weaker deeper into the space.
Sounding rocket is also called Research rocket. NASA uses 15 different types of sounding rockets. These rockets are of different sizes, single stage Super Arcas is 7 feet and four stage Black Brant XII is 65 feet tall. Sounding rockets carry instruments from 50 to 1,500 kilometers above the surface of earth. Sounding rockets are inexpensive.
