Photo: VCGScientists hope the precious samples, which are expected to amount to no more than 0.1 grams of material, could help shed light on the origin of life and the formation of the universe.The capsule carrying samples entered the atmosphere just before 2:30 am Japan time (1730 GMT Saturday), creating a shooting-star-like fireball as it entered Earths atmosphere en route to a landing site in Australia.”Six years and it has finally come back to Earth,” an official narrating a live broadcast of the arrival said, as images showed officials from Japans space agency JAXA cheering and pumping their fists in excitement. A few hours later, JAXA confirmed the samples had been recovered, with help from beacons emitted by the capsule as it plummeted to Earth after separating from Hayabusa-2 on Saturday, while the fridge-sized probe was some 220,000 kilometers away.”We found the capsule! Together with the parachute! Wow!” the missions Twitter account announced.People who had gathered at a public viewing site near JAXAs office in suburban Tokyo – despite the event taking place a few hours after midnight – also erupted with cheers.”Im extremely happy because the capsule has returned home safely, Hayabusa-2 did a great job,” a primary school boy said.The capsule was recovered in the southern Australian desert, and will now be in the hands of scientists performing initial, noninvasive analysis including checking for any gas emissions.It will then be sent to Japan.The samples were collected by Hayabusa-2, which launched in 2014, from the asteroid Ryugu, some 300 million kilometers from Earth. The probe collected both surface dust and pristine material from below the surface that was stirred up by firing an “impactor” into the asteroid.RELATED ARTICLES:Previous mission experience to ensure safe soft landing for Chang’e-5, likely on Tuesday: space analystsRussia plans to develop its own space station SpaceX’s historic human spacecraft launch a milestone success NASA, SpaceX launch first crew rotation mission to spacePosted in: ASIA-PACIFICvar wxs = (function() {return navigator.userAgent.toLowerCase().indexOf(micromessenger) !== -1})();if (!wxs) {/* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */var disqus_shortname = globaltimes; // required: replace example with your forum shortnamevar disqus_identifier = 1209112;/* * * DONT EDIT BELOW THIS LINE * * */(function () {var dsq = document.createElement(script); dsq.type = text/javascript; dsq.async = true;dsq.src = https:// + disqus_shortname + .disqus.com/embed.js;(document.getElementsByTagName(head)[0] || document.getElementsByTagName(body)[0]).appendChild(dsq);})();}Please enable JavaScript to view the comments powered by Disqus.blog comments powered by Disquswindow._taboola = window._taboola || [];_taboola.push({mode: thumbnails-a,container: taboola-below-article,placement: below article,target_type: mix});load_file(“/includes/adv_right.html”);load_file(“/includes/footer.html”);$(document).ready(function($){$(“#channel-list .row-content”).each(function(){  if($(this).children().length==1){$(this).children().css(width,100%);}
