'''AzaadiSAT''' was an [[India|Indian]] Earth observation 8U [[CubeSat|Cubesat]] weighing around 8 kg developed by the Space Kidz India as a test payload on the maiden launch of the [[Small Satellite Launch Vehicle]] (SSLV). It was hitching a ride with [[EOS 02|EOS-02]], the primary satellite of the mission. The launch on 7 August 2022 was a failure in the rocket leading to imminent return to atmosphere for the rocket and the satellites (AzaadiSAT and EOS-02) it carried, destroying them all.

Its successor AzaadiSAT-2 was launched onboard [[SSLV-D2]].<ref>{{Cite web |title=SSLV-D2/EOS-07 MISSION |url=https://www.isro.gov.in/mission_SSLV_D2.html |access-date=2023-02-09 |website=www.isro.gov.in}}</ref>

==Development==
It was created to mark India’s 75th year of independence. This anniversary was being marked in 2022 by the Azadi Ka Amrit Mahotsav celebrations throughout the country, and the CubeSat was part of this campaign. AzaadiSAT was built by schoolgirls from 75 schools across India. 10 girls from each school were involved, for a total of 750 students involved {{Who|date=May 2026}}. The mission was created to give girls from lower-income backgrounds the opportunity to learn the fundamentals of spaceflight, as part of the United Nations theme of “women in space.” It gave a feeling of pride and importance to women when the satellite was launched<ref>{{Cite web |date=2022-08-06 |title=ISRO's new SSLV small satellite launcher debuts - mission success unclear |url=https://www.nasaspaceflight.com/2022/08/isro-sslv-debut/ |access-date=2022-08-07 |website=NASASpaceFlight.com |language=en-US}}</ref>

==Characteristics==
It carried 75 different [[payload]]s each weighing around 50 grams and conducting femto-experiments. Girl students from rural regions across the country were provided guidance to build these payloads. The payloads were integrated by the student team of "Space Kidz India". The payloads included a UHF-VHF [[transponder (aeronautics)|transponder]] working in [[amateur radio|ham radio]] frequency to enable voice and data transmission for amateur radio operators, a solid state [[PIN diode]]-based [[Geiger counter|radiation counter]] to measure the ionising radiation in its orbit, a long-range transponder and a selfie camera to take pictures of its solar panels and the Earth. The ground system developed by ‘Space Kidz India’ was to be utilised for receiving the data from this satellite.<ref>{{cite web | url=https://www.isro.gov.in/launcher/sslv-d1-eos-02-mission | title=SSLV-D1/EOS-02 Mission - ISRO | access-date=2022-08-07 | archive-date=2022-08-07 | archive-url=https://web.archive.org/web/20220807071752/https://www.isro.gov.in/launcher/sslv-d1-eos-02-mission | url-status=dead }}</ref>

'''AzaadiSAT-2''', the official successor of AzaadiSAT, was placed in a 450km circular orbit. It was launched onboard SSLV-D2. It features a modular [[satellite bus]] expansion system capable of transforming from 8U to 64U once in orbit {{Clarify|date=May 2026}}. Other payloads remains unchanged from the original AzaadiSAT.
