Volcano helios5/1/2023 The exceptions are the masts and antennae used during experiments and small telescopes that measure the zodiacal light and emerge from the central body. Most of the equipment and instrumentation is mounted in this central body. The central bodies are sixteen-sided prisms 1.75 metres (5 ft 9 in) in diameter and 0.55 metres (1 ft 10 in) high. Their scientific payloads have a mass of 73.2 kilograms (161 lb) on Helios-A and 76.5 kilograms (169 lb) on Helios-B. Helios-A has a mass of 370 kilograms (820 lb), and Helios-B has a mass of 376.5 kilograms (830 lb). As built by the main contractor, Messerschmitt-Bölkow-Blohm, they were the first space probes built outside the United States and the Soviet Union to leave Earth orbit. The Helios project was a joint venture of West Germany's space agency DLR (70 percent share) and NASA (30 percent share). The probes are no longer functional, but as of 2023 remain in elliptical orbits around the Sun. Helios-B performed the closest flyby of the Sun of any spacecraft until that time. The Helios project set a maximum speed record for spacecraft of 252,792 km/h (157,078 mph 70,220 m/s). As a joint venture between German Aerospace Center (DLR) and NASA, the probes were launched from Cape Canaveral Air Force Station, Florida, on December 10, 1974, and January 15, 1976, respectively. Helios-A and Helios-B (after launch renamed Helios 1 and Helios 2) are a pair of probes that were launched into heliocentric orbit to study solar processes. These latest Io images were taken during Juno's 49th trip around Jupiter.Helios-A: December 10, 1974, 07:11:01 ( UTC07:11:01) UTC But other moons in our solar system could potentially contain suitable conditions for life to evolve in their subsurface, like the Saturnian moons Enceladus and Mimas (and, of course, Europa). It's extremely unlikely a world swimming in lava could host conditions for even the hardiest of life to evolve. All this heat seeks to reach the surface, resulting in molten lava and extreme volcanism. This powerful push and pull creates profound heat inside a world that's a little larger than our moon. Io is tortured because it's stuck in a relentless "tug-of-war" between the massive Jupiter and two of Jupiter's other big moons, Ganymede and Europa - a world that might harbor a sizable ocean. "It's a real tortured moon," Bolton, who works at the Southwest Research Institute, a research organization that often partners with NASA, added. "We're marching closer and closer," Scott Bolton, the Juno mission's principal investigator, told Mashable.Ī speeding object collided with Jupiter and blew up, cool space footage shows (For reference, the moon is some 240,000 miles from Earth.) By year's end, the spacecraft will pass just some 930 miles, or 1,500 kilometers, from Io. Juno will swoop progressively nearer to Io as it loops around Jupiter and approaches the dynamic moon's orbit. In 2023, the views of Io will get increasingly clearer and more intriguing. The images allow planetary scientists and the public to spot surface features and volcanoes on Io - the most volcanically active world in our solar system. The March 1 images are Juno's "best images so far of Io's colorful surface," Jason Perry, a professional imaging processor who uploaded new photos to NASA's Juno website, noted online (Opens in a new tab). The pioneering Juno spacecraft, which arrived at Jupiter in 2016 and is now swooping by the planet's intriguing moons, recently snapped images of the Jovian moon Io from some 32,044 miles (51,570 kilometers) away. There's a moon teeming with lava-spewing volcanoes in our solar system, and a NASA spacecraft is getting closer to this intense world.
