A: AMOS-5 was an Israeli commercial communications satellite that ultimately failed. It was designed to provide telecommunications services and was operated by the Israeli company Spacecom. ### Q: When was AMOS-5 launched? A: AMOS-5 was launched on December 11, 2011, at 11:17:00 UTC. The launch took place from Baikonur Cosmodrome Site 81/24. ### Q: Who operated AMOS-5? A: AMOS-5 was operated by Spacecom, an Israeli satellite communications company. ### Q: What happened to AMOS-5? A: AMOS-5 experienced a loss of signal on November 21, 2015, rendering it inoperable. This event marked the failure of the satellite. ### Q: Where was AMOS-5 manufactured? A: AMOS-5 was manufactured by JSC Information Satellite Systems Reshetnev, a Russian company. Its payload was manufactured by Alcatel Space. ## Why It Matters AMOS-5 holds significance as an Israeli commercial communications satellite intended to expand Spacecom's service offerings, particularly in Africa. Its launch represented an effort to bolster Israel's presence in the global satellite communications market. The satellite's failure, marked by the loss of signal in 2015, had considerable commercial implications for its operator, Spacecom, and highlighted the inherent risks in satellite operations. Despite being manufactured in Russia, its operation by an Israeli company and its place in the AMOS series underscore its role in Israel's space endeavors. The incident served as a notable event in the history of commercial satellite failures, impacting service continuity and necessitating future replacement efforts like AMOS-17. ## Notable For - Its status as a failed Israeli commercial communications satellite after losing signal in 2015. - Being an Israeli-operated satellite manufactured by a Russian company, JSC Information Satellite Systems Reshetnev. - Its launch aboard a Proton-M heavy-lift launch vehicle, a Russian rocket. - The significant event of its loss of signal on November 21, 2015, cutting short its operational life. ## Body ### Overview AMOS-5, also known by its aliases Amos-5 and Amos 5, was an Israeli commercial communications satellite. It was classified as an instance of a communications satellite and was part of the AMOS series of satellites. Its NSSDCA ID is 2011-074A and its SCN is 37950. ### Technical Specifications AMOS-5 had a launch mass of 1972 kilograms and a dry mass of 1590 kilograms. It was powered by two spacecraft solar arrays, capable of generating 7600 watts of power. The satellite utilized the Ekspress-1000N spacecraft bus. It was designed to operate in a geostationary orbit. ### Launch Details The launch of AMOS-5 occurred on December 11, 2011, at 11:17:00 UTC. It was launched from Baikonur Cosmodrome Site 81/24, located in Kazakhstan. The launch vehicle used was a Proton-M heavy-lift rocket, specifically the 935-23 variant, with a Briz-M space tug (99525) assisting in orbit insertion. ### Operations and Events AMOS-5 was operated by Spacecom, an Israeli company. The primary manufacturer of the satellite was JSC Information Satellite Systems Reshetnev, a Russian entity, while the payload was manufactured by Alcatel Space. Key events in its operational life include: - **Rocket launch**: On December 11, 2011, from Baikonur Cosmodrome Site 81/24. - **Loss of signal**: On November 21, 2015, which led to the satellite's failure. ### Related Entities AMOS-5 followed AMOS-3 in the AMOS satellite series and was subsequently followed by AMOS-4. It was eventually replaced by AMOS-17. The AMOS series itself is distinct from the AMOS programming language. ## References 1. [Source](https://space.skyrocket.de/doc_sdat/amos-5.htm) 2.
