The satellite measures the force of the gravity present under the ocean to detect a subduction zone.

For about 40 seconds, the satellite measured a sharp pulse of gamma rays.

Other satellites can measure snowfall and follow climate changes.

But he admits that it hasn't been proven rigorously, because satellites can't measure underneath the ice.

The satellites measured the desert during the four-month rainy season, from July to October.

The satellite actually measured three phenomena.

Each satellite measures less than one cubic meter and weighs 150 kg (bus + payload).

The complete satellite weighed just under 2500 kg, was 5.3 m high, 3.6 m wide and measured 2.3 m in depth.

In January 1959, the Soviet satellite Luna 1 first directly observed the solar wind and measured its strength.

The satellite measures the temperature of the top millimeter of the ocean surface.
