Since the launch of the first artificial Earth satellite, Sputnik 1, on October 4, 1957, we launched thousands of spacecraft into Earth orbit and beyond. A fraction of them are still functioning, but what happened to the vast majority of them? “The Curious Droid” published another informative video titled “What happens to old spacecraft?”Continue reading Watch: What happens to old spacecraft?
As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.Continue reading Five space probes leaving the solar system (for now)
Launched by NASA on September 5, 1977, to study the outer solar system, the Voyager 1 is the furthest human-made object from Earth. As of January 10, 2019, the space probe is more than 13,491,481,615 miles (21,712,434,988 km) away from our home planet. It is also moving away at a speed of 38,026.77 mph (61,198.15 km/h) relative to the Sun. But, thanks to NASA’s Deep Space Network (DSN) Notes 1, we can still communicate with it (also with its sister, Voyager 2). But how far can Voyager 1 go before we lose communication?
The video published by the Primal Space channel below looks at how we communicate with Voyager and when it will eventually stop receiving our signals.Continue reading Watch: How far can Voyager 1 go before we lose contact?
According to a new study, microbes like those found in Earth’s deep ocean could potentially thrive in the underground ocean of Saturn’s icy moon Enceladus. Both molecular hydrogen (H2) and methane (CH4) already have been detected in the plume. Researchers have shown that Methanothermococcus
Twelve years ago, on January 19, 2006, aboard an Atlas V rocket, NASA’s New Horizons probe started its fantastic voyage of exploration with a spectacular launch from the Florida coast toward Pluto and the mysterious realm of the Kuiper Belt beyond.
