A damaged high-resolution camera must be rescued by a deconvolution algorithm as two spacecraft race toward Comet Tempel 1 - did they make it in time?
The deconvolution algorithm sharpened the blurred camera - did they make it in time?
In this episode, we follow the Deep Impact mission as engineers and scientists cope with a blurred high-resolution imager, autonomous targeting software, and an unpredictable comet in the crucial weeks before impact. The narrative traces the technical fixes, mission timeline, and choices that set up one irreversible moment: could a software patch and self-guiding code save the science?
Mission: Deep Impact
Date: July 4, 2005
Location: Comet Tempel 1
Person: Michael A'Hearn
Budget: $330 million
- The mission used two spacecraft: a 601 kg Flyby to observe and a 372 kg Impactor designed to collide and transmit until destruction.
- Launch occurred January 12, 2005 from Cape Canaveral on a Delta II rocket; the spacecraft entered safe mode the next day due to a temperature parameter.
- The Impactor carried 113 kg of copper to keep impact spectra attributable solely to the comet, and housed a mini-CD with 625,000 names.
- The high-resolution imager was found out of focus on June 9 due to an optical misalignment that surfaced in space thermal conditions.
- Ball Aerospace produced a deconvolution algorithm to mathematically sharpen images in place of any physical adjustment, validated before impact.
