Update on IDEA OSG 1 Mission
IN THE NEWS / December 18, 2017

Dear Supporters and Sponsors,


Thank you for your ongoing support.


Below is additional information on the conclusion of the IDEA OSG 1 mission based on results from investigations by Roscosmos and Glavkosmos.


On November 28, 2017 at 14:41:46 (JST), IDEA OSG 1 launched on a Soyuz -2.1b rocket from the Vostochney Cosmodrome.  The launch was nominal and initial indications pointed to a successful orbital insertion. However, officials soon lost contact with the mission and, following numerous failed attempts to connect to IDEA-OSG 1 and the other 18 payloads manifested on the Soyuz, it became apparent that there was a launch anomaly and an accident investigation committee was formed.


On December 14, 2017, Roscosmos and Glavkosmos officials announced that the failure of the rocket was caused by a problem in the algorithm of the Fregat attitude control system at the fourth stage of Soyuz-2.1b rocket.


Over the past 61 launches, the Fregat has successfully injected over 200 satellites into target orbits from Baikonur, Plesetsk, and Kourou launch bases. The Soyuz carrying IDEA-OSG 1 passed all required clearances by experts and no problem was found during ground tests. Roskosmos and Glavkosmos were in the process of correcting the algorithm and updated the verification plan, following a detailed review.


We regret that IDEA OSG 1 was lost and we were not able to meet the expectations of those who supported and contributed to the mission over the past three years. We would like to reiterate our gratitude for your help and cooperation as we designed, built, tested and shipped our first satellite.  Your many messages of sympathy and support after the launch have been invaluable. Thank you.


Despite our desire to create a more comprehensive map of orbital debris in low-Earth orbit, following internal discussions with investors and company officials, we have decided to defer any development of a follow-on debris monitoring mission. ASTROSCALE continues to support all efforts to monitor and measure orbital debris, but for the time being we will focus on design and development of ELSA-d, our debris removal technology mission.


ASTROSCALE’s mission remains the same: to maintain a sustainable orbital environment and secure long-term spaceflight safety. We appreciate your understanding and thank you for your support of this important mission.


Go Space Sweepers!








On February 1, Roscosmos officials announced that Soyuz-2.1a launch vehicle successfully lifted off from VOSTOCHNY Cosmodrome and delivered the payloads to their target orbits. For more, please visit from here.
