STS-61-C (Columbia)

 1986-003A

---

61-C was originally scheduled to fly Satcom K-1, Leasat 5 and MSL-2. Leasat 5 was not ready and was replaced by HHG-1 and GBA-1.

On 1985 Dec 19, the count got to within 14 s of launch before the computer called an RSLS hold because of a hydraulic power unit failure. The launch attempt of Jan 12 was successful, and that evening Columbia deployed the Satcom K2 satellite into orbit. An IR camera took pictures of the deployment.
