Officials have scheduled the next launch attempt of a Boeing [NYSE: BA] Delta II launch vehicle carrying the ARGOS satellite for the U.S. Air Force for Tuesday, Feb. 23, from Vandenberg Air Force Base, Calif. The one-hour launch window opens at 2:10 a.m. PST.

The launch was scrubbed Saturday morning after a momentary spike in one of the two power sources to the first stage electronics package was observed. The Boeing team isolated the cause to the first stage center body which houses the power and control box and the first stage electronics package. Technicians replaced both the power and control box and electronics package and are performing revalidation tests on the hardware and wiring.

The ARGOS launch has two NASA-sponsored secondary payloads, the Ørsted satellite for Denmark and the SUNSAT micro-satellite for South Africa.

The launch will be broadcast live beginning at 2 a.m. PST and ending after spacecraft separation, approximately one hour and 40 minutes later. The satellite coordinates are Ku-band: GE 3, transponder 19 at 87 degrees West. Uplink frequency is 14380 horizontal, Downlink frequency 12080 vertical.
