Life in space may be closer to Earth than we think: NASA launches a probe to search for it (video).

Life in the Solar System is not only being searched for on Mars. Scientists believe that Europa, one of Jupiter's moons, is potentially intriguing. On October 14, the largest spacecraft ever developed by NASA will embark on its mission. The journey to Jupiter will take 5.5 years, covering a distance of 2.9 billion kilometers.

Researchers will not be looking for specific signs of life, but rather determining whether Europa has the components necessary for life to exist. According to scientists, beneath Europa's icy surface lies a liquid ocean, which the Europa Clipper mission aims to explore.

Previously, Jupiter's moon was studied in the 1990s, but the new probe will be equipped with numerous advanced instruments to analyze the structure and composition of Europa's icy surface, its depth, the salinity of the ocean, and how the ice layer interacts with the liquid water below. There is little hope for a highly developed civilization; scientists believe that the ocean may contain bacteria.

After more than five years of traveling to Jupiter’s moon, the mission itself will last four years. The probe will fly past Europa 49 times, with the closest approach being just 25 km from the surface.

Earlier, "Telegraph" reported that Elon Musk's company SpaceX successfully landed a rocket booster after launch for the first time in history. An experimental method was used, as the previous four attempts had failed.
