Drag and Atmospheric Neutral Density Explorer
DANDE (or Drag and Atmospheric Neutral Density Explorer) is a 50 kg class spacecraft developed by the University of Colorado Boulder was the winner of the 5th iteration of the Air Force Research Laboratory's University Nanosat Program.〔(【引用サイトリンク】 title=CU-Boulder Students Win First Place in National Nanosatellite Competition )〕
Due to a failure in a spacecraft system, the ground team was uanable to actively command the satellite and spacecraft became just a passive object in Earth orbit by which some passive drag characteristics might be deduced.
== Status ==
DANDE launched on September 29, 2013 and correctly separated from the launch vehicle. After a month of assessing spacecraft health, successful separation of the Lightband Adaptor Bracket (LAB) was conducted on October 30 over the Starfire Optical Range in Maui. The next step was planned to be spin-up and alignment.
However, a failure in a spacecraft system prevented that. The DANDE team reported on January 9, 2014 that they had "been unable to actively command DANDE (that they were ) collecting passive drag data through analysis of the TLE's."〔(reports )〕
