A silent spacecraft drifting in space has been brought back into contact, restoring momentum to one of Europe\u2019s most intricate solar missions. After nearly a month without communication, engineers managed to reconnect during a brief and unexpected window. The recovery keeps the European Space Agency (ESA)\u2019s Proba-3 mission alive.<\/p>\n

Launched in 2024, Proba\u20133 relies on two spacecraft flying in precise formation to simulate a solar eclipse at an altitude of more than 60,000 kilometers. One satellite blocks the Sun using a 1.4-meter disk, while the other observes the faint solar corona, a region still difficult to study directly.<\/p>\n

A Chain Reaction Led To Loss Of Contact<\/p>\n

As explained by\u00a0an\u00a0ESA statement<\/a>, the incident began on February 14, when the spacecraft carrying the coronagraph <\/a>lost its orientation after a series of failures. Its solar panels turned away from the Sun, cutting off its power supply.<\/p>\n

As its batteries drained, the spacecraft entered a survival mode and stopped communicating. It remained in this state, tumbling through space, for several weeks. The loss of orientation triggered the entire sequence that led to the blackout.<\/p>\n

A Fleeting Moment Of Sunlight Restored Communication<\/p>\n

Engineers identified a critical opportunity when the tumbling spacecraft briefly exposed its solar panels to sunlight. That limited energy allowed them to attempt a reconnection.<\/p>\n

Teams in Spain acted quickly and successfully re-established contact. According to ESA Director<\/a> Josef Aschbacher<\/a>, they \u201csaw that some sunlight is actually hitting the solar panels.\u201d Proba-3<\/a> has since regained a stable orientation.<\/p>\n

\u201cThe spacecraft\u2019s solar panel is facing\u00a0the sun<\/a>, powering the essential electronics on board, and charging the battery with the remaining power,\u201d stated ESA officials, as quoted by Space.com<\/a>. \u201cAfter a month of floating in space and exposed to extreme cold, onboard systems need time to warm up before any major actions are taken.\u201d<\/p>\n

System Checks Will Decide Next Phase<\/p>\n

The second spacecraft, tasked with blocking the Sun\u2019s light, remained operational and continued to track its partner throughout the incident. Part of the mission therefore remained active.<\/p>\n

Engineers\u00a0now turn\u00a0their attention to evaluating the condition of the recovered spacecraft. Instruments will be switched back on step by step to determine any damage. As Proba-3 mission Manager Damien Galano<\/a> said in a press release<\/a> published by ESA on March 19, the return of communication is \u201ca great relief,\u201d as the coronagraph is central to the mission\u2019s objectives.<\/p>\n

But, the objective remains unchanged: to study the solar corona<\/a>, a vast, still largely mysterious region spanning millions of kilometers.<\/p>\n","protected":false},"excerpt":{"rendered":"A silent spacecraft drifting in space has been brought back into contact, restoring momentum to one of Europe\u2019s…\n","protected":false},"author":2,"featured_media":486821,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[90,416,56,54,55],"class_list":["post-486820","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-science","tag-space","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/486820","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=486820"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/486820\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/486821"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=486820"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=486820"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=486820"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
