Among the disciplines in track &amp; field is the relay race.  This race is often trickier than it looks with the crucial handoff from one runner to another, one misstep can be the difference between a medal or not.<\/p>\n\n\n\n<p>Now picture the air-to-air refueling of military aircraft.  It\u2019s the same thing, an intricate ballet of two moving objects.  The tanker and the jet, that must move three dimensionally in perfect harmony, or else the naval aviator, who might be very far away from his or her carrier, could be stranded.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Increasing the longevity of satellites in space<\/h2>\n\n\n\n<p>But let\u2019s take it to another level, <em>literally<\/em>, in space. You may not be aware, but satellites don\u2019t orbit the earth indefinitely.  They have a service life, and until recently, that meant that they would be eventually decommissioned. However, over the last few years, Northrop Grumman has invented a <a href=\"https:\/\/youtu.be\/ZQsVDTsAMxQ?si=hDtJDeZbklbyar9D\" target=\"_blank\" rel=\"noreferrer noopener\">series of satellites that extend the life of existing satellites<\/a>. How do they do it? With the same intricate ballet and handoff that might exist in a relay race or in an air-to-air refueling mission!<\/p>\n\n\n\n<p><a href=\"https:\/\/youtu.be\/JUnA88PQY3k?si=sOaBdNcidG-yOMpL\" target=\"_blank\" rel=\"noreferrer noopener\">On 12 April 2021, Northrop Grumman&#8217;s MEV-2 (Mission Extension Vehicle)<\/a> satellite successfully rendezvoused and docked to Intelsat 10-02. The maneuver was completed at 17:34 UTC, marking the first time a satellite servicer docked with an <strong>in-service<\/strong> commercial broadcast satellite in geosynchronous orbit (GEO).<\/p>\n\n\n\n<p>But this was anything but a simple maneuver, because the two satellites are hurtling through space around earth and one misaligned touch from the MEV could knock the Intelsat out of orbit and disrupt the broadcasts that it was carrying around the world and send it flying into space.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"MEV-1 Mission Profile\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/_rgglvA5DdI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">MEV-1 Mission Profile<\/figcaption><\/figure>\n\n\n\n<p>For a comprehensive collection of YouTube videos showcasing MEV in action, check out <a href=\"https:\/\/eur01.safelinks.protection.outlook.com\/?url=https%3A%2F%2Fwww.youtube.com%2F%40northropgrummanmedia%2Fsearch%3Fquery%3DMEV&amp;data=05%7C02%7Cmario.vacca%40siemens.com%7Cb554d6c24d514c7a596308dc5576804f%7C38ae3bcd95794fd4addab42e1495d55a%7C1%7C0%7C638479214703891031%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&amp;sdata=7JbcvbAH60%2B7CoyZun0HXJ6e9apKcIfMLz3tOWJFQrQ%3D&amp;reserved=0\" target=\"_blank\" rel=\"noreferrer noopener\">this curated playlist.<\/a><\/p>\n\n\n\n<p>How did Northrop Grumman ensure that this mission would proceed flawlessly?
