Both missions made numerous pictures of Venus. These were the first ever panoramic pictures of the surface of the second planet that is considered Earth’s ‘sister’ in mass and size. The missions significantly changed the scientific conceptions of Venus prevailing at that time.\u003c\/p\u003e\n\u003cp\u003eFirst, the space probes, consisting of an orbiter and a descent module each, entered Venus’ orbit, and then their descent modules separated from the orbiters. By so doing, the orbiters remained on the trajectories that allowed them to fly over the landing site when transmitting data. The synchronisation of the module’s descent, the orbiter’s overfly, and the transmission, reception, and retransmission of radio signals to Earth were extremely difficult technical tasks being performed in deep space for the first time.\u003c\/p\u003e\n\u003cp\u003eOne of the most interesting technical solutions first used by Venera 9 and Venera 10 was the optical-mechanical scanner that allowed humans to see the surface of the ‘second planet’ in detail for the first time.\u003c\/p\u003e\n\u003cp\u003eThe space probes’ scientific equipment made it possible to conduct multiple remote and contact studies en route to Venus, in Venus’ orbit, and on the planet’s surface.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"tk-coins.com","offers":[{"title":"Default Title","offer_id":54369383022925,"sku":null,"price":219.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/2860\/9101\/files\/20253Ven01.jpg?v=1784743602","url":"https:\/\/tk-coins.com\/products\/2025-3-rubles-the-50th-anniversary-of-the-soft-landing-of-descent-modules-on-venus-and-the-acquisition-of-panoramic-images-of-the-surface-of-venus","provider":"tk-coins.com","version":"1.0","type":"link"}
