Landsat 7 Earth Satellite

Landsat 7 weighed 2,200 kilograms when it was launched!   

It orbits the Earth at a height of about 00 kilometers. 

It takes thousands of pictures of Earth so that scientists can study how Earth is changing!  

Landsat 8 Earth Satellite

Landsat 8 orbits the Earth once every 99 minutes. 

It is powered by a single solar array. 

It carefully observes how the Earth’s land areas, polar caps, and climate change!

Spitzer Space Telescope

Spitzer took amazing photos of the universe for 16 years. 

It found an undiscovered ring around Saturn. 

It found many Earth-sized exoplanets! 

Juno Space Probe to Jupiter

Juno took 5 years to reach its orbit around

Juno spins in place to keep itself stable
as it orbits Jupiter. 

Every 53 days, it gets close enough to
Jupiter to take photos and measurements!

International Space Station

16 countries helped build the International Space Station! 

It took 136 space flights to bring all the pieces up to space and put the station together. 

It is the third brightest object in the sky, after the Moon and Venus.

Curiosity Mars Rover

Curiosity was the first spacecraft to land with a parachute and rocket landing system. 

It is the size of a car and can travel about 2 meters per minute.   

It is designed to be able to roll over rocks as big as its wheels!

InSight Mars Lander

InSight is the first Mars lander to study deep under the planet’s crust. 

It is 6 meters long when it has its solar panels out.   

It has a seismometer to look for earthquakes on Mars! 

Perseverance Mars Rover

Perseverance explores Mars looking for
signs of ancient life. 

It is the first rover to carry and launch a

Perseverance is collecting soil samples to
return to Earth in the future! 

Kepler Space Telescope

Kepler searches the Milky Way to find planets like Earth.   

Its telescope is so strong that if it orbited Earth, it could detect a single porch light turning on and off. 

It had the largest camera ever launched
into space!   

Lunar Reconnaissance Orbiter

LRO has traveled over 200 million kilometers while orbiting the Moon.
It confirmed that the Moon is cooling and shrinking!
It took over 6 billion measurements of the Moon’s surface.

Chandra X-Ray Observatory

Chandra weighs 4,800 kilograms.
Chandra’s mirrors are coated in iridium, a shiny precious metal.
It has observed light that traveled
through space for more than 12 billion years!
