“JUNO PROBE MAKES HISTORY BY ENTERING JUPITER’S ORBIT AFTER FIVE-YEAR JOURNEY”

Last night, NASA and its Juno probe made history by entering a new probe in orbit around Jupiter. The Juno spacecraft, which had left Earth five years ago, finally entered Jovian orbit after a 35 minute rocket engine manoeuvre to slow down its approach to the planet and get caught by its gravity. Unlike other engine firings in the past, Juno’s manoeuvre was especially dangerous since no previous spacecraft had ever dared to pass so close to Jupiter; its intense radiation belts can destroy unprotected electronics. Luckily, since the probe was built like a tank with titanium shielding, a few minutes later, a sequence of tones transmitted from the spacecraft confirmed the braking manoeuvre had been a smashing success prompting wild cheering at NASA’s mission control in Pasadena, California. “All stations on Juno co-ord, we have the tone for burn cut-off on Delta B,” Juno Mission Control had announced. “Roger Juno, welcome to Jupiter.” Juno’s main objective is to sense Jupiter’s structure and chemistry to gather clues on how the gas giant formed some four-and-a-half-billion years ago. However, much of this observation will not take place until mid-October when Juno performs a second rocket engine burn to tighten its orbit to just 14 days. By then, Juno will be able to answer some interesting questions about the planet including where it formed  in the early Solar System and whether Jupiter has a solid core or a core made of compressed gas. After the mission ends, Juno is scheduled to dive into Jupiter’s atmosphere in February 2018 to ensure that there is no possibility of it crashing into and contaminating any of Jupiter’s large moons.

NASA’s Cassini spacecraft shows Earth and its moon from between Saturn’s rings

NASA’s Cassini spacecraft, which orbits Saturn, took a picture of Earth from between Saturn’s rings — with Earth’s moon at its side.

Captured at 1:41 a.m. Eastern on April 12, 2017, the spacecraft was 870 million miles away from its home planet when it took the image.

Earth is seen as a tiny bright speck in the center of the picture. Upon cropping and zooming in, its moon can be seen to the left as an even smaller dot. The photograph, captured by the Imaging Science Subsystem, doesn’t clearly show which part of Earth is facing the ringed planet at the time the picture was taken, but NASA has revealed it is the southern Atlantic Ocean.
