is 276 kg
Lenth of mission: 5 to 10 years
the primary mirror is a single glass mirror 2.4 meters in diameter
designed to be serviced by astronauts
Orbits Warth roughly every 95 minutes at a height of 547 Km
Placed in Orbit arounf Earth by astronauts aboard the space shuttle discovery
James Webb Telescope
Mass of the mirror
is 828 KG
Lenth of mission more than 25 years
Primary Mirror has 18 segments made of beryllium and is about 6.5 m in diameter
Located too far from Earth to be serviced by astronauts
Positioned about 1.5 million km from Earth at the L2 point
Will be launched on Ariane 5 rocket and will take a month to reach the L2 Orbital point
Use a mirror to collect and focus light
