In so doing, JAXA became the fifth national space agency to achieve a soft landing on the Moon \u2013 after NASA, the Soviet space program (Interkosmos), the European Space Agency, and the China National Space Agency (CNSA). SLIM has since experienced some technical difficulties, which included upending shortly after landing, and had to be temporarily shut down after experiencing power problems when its first lunar night began.<\/p>\n<p>On the Moon, the day\/night cycle lasts fourteen days at a time, which has a drastic effect on missions that rely on solar panels. Nevertheless, SLIM managed to reorient its panels and recharge itself and has survived three consecutive lunar nights since it landed. However, when another lunar night began on May 27th, JAXA announced that they had failed to establish communications with the lander. As a result, all science operations were terminated while mission controllers attempt to reestablish communications, which could happen later this month.<\/p>\n<p><span id=\"more-167242\"\/><\/p>\n<p>As JAXA stated via its official X account (formerly Twitter):<\/p>\n<blockquote class=\"wp-block-quote\">\n<p>\u201cWe tried again on the night of the 27th, but there was no response from #SLIM. As the sun went down around SLIM on the night of the 27th, it became impossible to generate electricity, so unfortunately this month\u2019s operation will end. Thank you very much for the overwhelming support you have shown us since our post the day before.\u201d<\/p>\n<\/blockquote>\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\">\n<div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"525\" data-dnt=\"true\">\n<p lang=\"ja\" dir=\"ltr\">27??????????????????<a rel=\"nofollow\" href=\"https:\/\/twitter.com\/hashtag\/SLIM?src=hash&amp;ref_src=twsrc%5Etfw\">#SLIM<\/a> ???????????????27??????SLIM??????????????????????? ?????????????????????????????????????????????????????<a rel=\"nofollow\" href=\"https:\/\/twitter.com\/hashtag\/JAXA?src=hash&amp;ref_src=twsrc%5Etfw\">#JAXA<\/a><\/p>\n<p>\u2014 ????????SLIM (@SLIM_JAXA) <a rel=\"nofollow\" href=\"https:\/\/twitter.com\/SLIM_JAXA\/status\/1795310224548798726?ref_src=twsrc%5Etfw\">May 28, 2024<\/a><\/p><\/blockquote>\n<\/div>\n<\/figure>\n<p>JAXA further indicated that the command transmission to restore communication was performed using an \u201cunplanned ground station antenna\u201d and with the cooperation of JAXA\u2019s tracking network.\u201d They also indicated that they plan to try reestablishing communications once the current lunar night ends later this month \u2013 at which point, they expect the lander will be recharged. \u201cThe power was turned off overnight, so we hope that the whole system will be reset and restarted,\u201d they wrote. <\/p>\n<p>The SLIM mission also carried two rovers, which separated from it in lunar orbit and landed independently on the same day. Known as the Lunar Excursion Vehicle-1 and -2 (LEV-1 and LEV-2), these rovers are the first Japanese robotic missions to traverse and explore the lunar surface. According to JAXA, LEV-1 is the world\u2019s first \u201chopping exploration rover\u201d while LEV-2 is the world\u2019s smallest and lightest. During the four months since they landed, LEV-1 has measure the local temperatures, topography, and taken images.<\/p>\n<p>The rovers can conduct operations autonomously and transmit data to Earth directly without assistance from the lander. As such, JAXA\u2019s mission controllers are still likely to hear from LEV-1 and LEV-2 while attempting to restore communications with SLIM.<\/p>\n<p><em>Further Reading: <\/em><a rel=\"nofollow\" href=\"https:\/\/twitter.com\/SLIM_JAXA\"><em>Twitter.com<\/em><\/a><\/p>\n<div class=\"sharedaddy sd-block sd-like jetpack-likes-widget-wrapper jetpack-likes-widget-unloaded\" id=\"like-post-wrapper-24000880-167242-665fd09a81968\" data-src=\"https:\/\/widgets.wp.com\/likes\/?ver=13.2#blog_id=24000880&amp;post_id=167242&amp;origin=www.universetoday.com&amp;obj_id=24000880-167242-665fd09a81968&amp;n=1\" data-name=\"like-post-frame-24000880-167242-665fd09a81968\" data-title=\"Like or Reblog\">\n<h3 class=\"sd-title\">Like this:<\/h3>\n<p><span class=\"button\"><span>Like<\/span><\/span> <span class=\"loading\">Loading&#8230;<\/span><\/p>\n<p><span class=\"sd-text-color\"\/><a rel=\"nofollow\" class=\"sd-link-color\"\/><\/div>\n<\/p><\/div>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/www.universetoday.com\/167242\/japans-lunar-lander-fails-to-check-in\/?rand=772204\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On January 19th, 2024, the Japanese Aerospace Exploration Agency (JAXA) successfully landed its Smart Lander for Investigating Moon (SLIM) on the lunar surface.
