Data for the launch can be found at: https://celestrak.org/NORAD/elements/table.php?INTDES=2023-155The table is showing only eight payloads in 570 km orbits, compared to the expected 10 cubesats. ESA also said"On this commercial flight, ten smaller secondary satellites were set to be released into orbit around 50 minutes after the two main passengers. All separation commands were properly executed and confirmation of the separation was acquired for eight satellites, the separation of the last two cubesats is still to be confirmed."https://www.esa.int/Enabling_Support/Space_Transportation/Vega/Vega_flies_to_bring_satellites_to_spaceAnybody know which cubesats failed to separate?
Sirli SarapuuCommunications Lead at Tudengisatelliit / Owner at Sirli Disain OÜ2 Tage🛰️Estonian Student Satellite ESTCube-2 was launched to orbit on 9.10 at 4:36 Estonian time. While it is great that our satellite is in orbit, there is an unexpected problem with the satellite and we haven't gotten into contact with it yet. 🛰️Our team has analyzed several possible causes of why the satellite has not sent a signal or is not sending anymore (assuming some of the early & uncertain packets were ESTCube-2's). As of now, we think that the batteries could be too drained to boot up properly. 🛰️We have added a lot of solar cells on ESTCube-2 and we hope that in a few days it has gathered enough energy to boot correctly. From that point on we have commands already in place to put it into a deep sleep mode and then in between, command the cubesat as necessary.🛰️Together with radio amateur and cubesat communities will continue listening for the ESTCube-2 signal, while investigating the satellite's table model behavior during the initialization sequence. We cannot rule out an option that a critical system or component, such as solar cells or power harvesting components, have been broken during the launch, in which case we will not be able to find out what exactly happened.🛰️Keep your fingers crossed for us and hopefully everything will get figured out and fixed!
... Following two other ignitions of the AVUM, ten cubesats from the auxiliary payload all successfully separated; the confirmation of the separation was acquired for 8 satellites, the separation of the last 2 cubesats is still to be confirmed. ...
Space-Track now renamed THEOS-2 as "T2V" Anyone familiar with this designation?
During the Information session from ESA’s 317th Council for Media, ESA says that the Vega VV23 flight is now under official investigation.The investigation is led by Arianespace and Avio, with support from ESA.
They assume that the two Cubesats remained attacched to the SSMS (deployer) but the command was sent correctly.The SSMS is provided by Avio.
Asked about the future flights of Vega, they said that the next flight won't use the SSMS Deployer and that Vega flights are not grounded due to this failure.Unclear if the next mission using SSMS will be delayed or not, and how we'll be updated about the investigation...
Do you know if the failed deployer is considered to be part of the payload or of the launch vehicle?
The deployer is the SSMS, which is not part of the launch vehicle, but an addition for certain missions that requires multiple small satellites to be deployed.The SSMS system is produced also by Avio, the manufacturer of *most parts* of Vega...
