The amount of remaining cold gas decreases by about a dozen grams per day and is reaching its end in early 2025. The Gaia science observations will therefore end on 15 January 2025, meaning that no more nominal science data will be acquired by Gaia after that date. <br/><br/>After Gaia’s science observations end on 15 January 2025, a period of technology tests will commence. These technology tests will allow us to study in more detail the behaviour of some spacecraft and instrument components, with the potential of further improving the Gaia calibrations and aiding the design of future space missions. After these tests, which will last several weeks, the Gaia spacecraft will leave its orbit around the Lagrange point L2 to be put into its final heliocentric orbit, away from Earth’s sphere of influence. Eventually, the Gaia spacecraft will be passivated in March/April 2025 and reach its well-deserved retirement.<br/><br/>When Gaia avoided the Draconid storm with a commanded safe-attitude manoeuvre, this changed Gaia&#39;s attitude with respect to the Sun and a brightness of about 14 to 15 magnitude in the same passband was observed by GBOT. <br/><br/>It is assumed that this brightness will be reached during the end of observation testing, when Gaia is repositioned to similar angles with respect to the Sun.<br/><br/><a href="https://www.cosmos.esa.int/web/gaia/observe-gaia?fbclid=IwZXh0bgNhZW0CMTAAAR12rF5N_I6WIrGoE_h50T5hn4GJkdx5H8hZyo-WdwHduSD6aurOxAnJSa8_aem_bzIsRrignSL-Jo0fObMDcA">https://www.cosmos.esa.int/web/gaia/observe-gaia?fbclid=IwZXh0bgNhZW0CMTAAAR12rF5N_I6WIrGoE_h50T5hn4GJkdx5H8hZyo-WdwHduSD6aurOxAnJSa8_aem_bzIsRrignSL-Jo0fObMDcA</a><br/><br/><a href="https://www.cosmos.esa.int/web/gaia/end-of-observations?fbclid=IwZXh0bgNhZW0CMTAAAR01IOjxUz2zA0XjzvAIpRxM25Qywex0DhGEGc0IoJgP2OghmFWsHKC9oUA_aem_FYNoKY_Y9Zw4fFgB-ng5WQ">https://www.cosmos.esa.int/web/gaia/end-of-observations?fbclid=IwZXh0bgNhZW0CMTAAAR01IOjxUz2zA0XjzvAIpRxM25Qywex0DhGEGc0IoJgP2OghmFWsHKC9oUA_aem_FYNoKY_Y9Zw4fFgB-ng5WQ</a> 2024-12-07T13:00:13Z https://yabu.me/nevent1qqsw94q2ehm9ur8f2v8j6vraq7yylt2xrgp27k25m86haadh9qnqqfszyzmevmt2hpkj0kl05awh66kpl8x5rktm2z8c9alyfeh7uj5rr6hhzt90qzz In reply to <a href='/nevent1qqsdwc5ztq94wn0uuv7dx5jz69dpljgh4ytu70fx4snyzu3hmynhntcpljct9'>nevent1q…jct9</a><br/>_________________________<br/><br/>I really really dislike the Google AI pretend search results.
