space probe

Voyager 1 is one of two identical space probes.

They then used a laser beam to excite the droplets and mass spectral analysis to mimic what instruments on the space probe will detect.

A space probe nearing its 50th birthday has stopped contacting Earth and soon communications could be ceased entirely.

Four years later, she joined a four-day mission on the same spacecraft when it sent the Magellan robotic space probe to Venus to map the planet’s surface.

Before the mission ended nearly 20 years later, the Cassini-Huygens space probe managed to provide unprecedentedly detailed readings about the planet Saturn, along with its rings and various satellites.
