Hi All,
While Delfi-C3 is rapidly approaching her second birthday on 28th of April, the team got a warning from The United States Joint Space Operations Center about a close approach of COSMOS debris and Delfi-C3. Today at 14:49 UTC the two objects will approach each other almost heads on with a difference velocity of 15km/s (yes, kilometers a second!). Fortunately, the predicted distance between the objects will be 492m, so they will miss each other. Although these close approach warnings were given to other satellites as well, and the chance that something really happens is very small, we would like to encourage people to listen for Delfi-C3 and send in telemetry. Please have a look at the mission operations page at http://www.delfic3.nl/index.php?option=com_content&task=view&id=93&a... for frequency info and the latest RASCAL downoad.
**PLEASE NOTE** Due to Delfi-C3s habit of sometimes switching off from science mode, you might hear nothing while Delfi-C3 is fine. Don't panic! but please do listen the orbits after and post your findings on http://oscar.dcarr.org
Thanks on behalf of the Delfi-C3 team,

Hi All,
Delfi-C3 and the COSMOS debris missed each other by more than 700 meters, so no harm was done as far as we know. Delfi-C3 still performs nominal and is approaching its second birthday! Thank you for sending in your telemetry and posting the status on http://oscar.dcarr.org/ !
