In the coming weeks we will interview some crucial members of the Aeolus group to discover more about flying and operating among the most successful objectives ever zipped ESA– and the pioneering attempt to bring it home.
ESAs wind mission, Aeolus, will soon go back to Earth in a first-of-its-kind assisted reentry.
Introducing Trismono Candra Krisna
He has played an essential function in the Aeolus objective, recently coordinating efforts to extend the mission well beyond its planned life time by increasing the output of Aeoluss special wind-mapping UV laser, ALADIN.
At the end of the objectives life, he has actually led Aeolus End-of-Life (EOL) tests to investigate concerns observed during in-orbit operations and to transfer understanding and innovation to future objectives, consisting of Aeolus-2.
Since 2021, Trismono Candra Krisna has worked as the Aeolus Instrument Performance Engineer at the European Space Research and Technology Centre (ESTEC) in Noordwijk, The Netherlands.
Trismono at front centre, with coworkers from the Aeolus mission and market groups upon an effective campaign to extend the life time of Aeolus with a tweak to its laser.
What is your function in the Aeolus objective?
My main role during small operations was to keep an eye on the instruments efficiency based upon housekeeping telemetry and science data. I performed analyses and proposed actions to improve the performance or preserve moved to functional (Level 2/L2) data.
Since the start of this year, I have started working on Aeolus-2 to support the instrument performance. There are a lot of lessons learned that can be moved from its predecessor..
Whats your favourite part of the function?
The leading favourite is when I can identify a concern, either in-orbit or on-ground, and define the option. When the service is ultimately used and shows the anticipated outcome( s), it is a real pleasure. In addition, I really enjoy gaining from Aeolus professionals from industry, DISC (Data, Innovation and Science Cluster), and ESA.
What is the most difficult aspect of the objective?
Aeolus has been constantly difficult, so there are no dull moments. Someone said, “Aeolus has been in commissioning up until its decommissioning.” In practice, to maintain the efficiency with numerous problems we have in-orbit, it is incredibly tough and demanding.

Whats been your emphasize of the Aeolus mission?
Second is the EOL test where we have the chance to examine in information and search for answers to issues during small operations.
There are three highlights because I joined the mission in late 2021. First is the switch-over to the laser A in 2022, which fully recuperated the transmission and enabled us to continue the mission even further beyond its style lifetime.
Third is the record-breaking UV energy during the EOL test. We recently beat the record for a spaceborne UV laser– 182mJ. The previous best was NASAs LITE instrument, with 169mJ.
How did you enter into area? What led you to ESA?
I moved to the Netherlands in early 2019, working at the Netherlands Institute for Space Research (SRON), Utrecht. I began to actively use for a position at ESTEC.
When youre not dealing with Aeolus, what do you like to do?
Apart from area, I would be happy to end up being an F1 race engineer.
Wonderful.
Explain the Aeolus objective utilizing just one word.
Whats the most interesting aspect of flying Aeolus?
PB: Aeolus is a demonstrator objective, going where no spaceborne objective has actually gone before! I moved to the Netherlands in early 2019, working at the Netherlands Institute for Space Research (SRON), Utrecht.
Aeolus has actually been constantly difficult, so there are no dull moments. In practice, to keep up the efficiency with numerous concerns we have in-orbit, it is extremely difficult and requiring.
To me, it is individuals (ESA, DISC, and industry) interacting for the success of the objective. Now, I have actually begun to miss them.
In addition, I truly enjoy learning from Aeolus experts from market, DISC (Science, data and development Cluster), and ESA.
