Hinode

 2006-041A


ISAS SOLAR-B was launched on the final M-5 in 2006. It was named Hinode ('Rising Sun') and carried optical and X-ray solar telescopes. The satellite involved NASA's participation under the Solar-Terrestrial Probe series of the Sun-Earth Connection theme, with an optical instrument package developed by Lockheed's Palo Alto solar group and an X-ray telescope developed by Lockheed and the Smithsonian Astrophysical Observatory. The SOLAR-B satellite was built by MELCO.

The 0.5-meter SOT has a resolution of less than 0.1 arcsec across a few-arcmin field of view; the EIS and XRT reach 1 arcsecond with a much larger field 1/2 degree field of view.

The M-V-7 has a launch mass of 140t. It carried subsatellites HIT-SAT and SSSAT.

Hinode's Mass is 900 kg. Box + 2 panels, span is 10.3m. Size is 1.6m x 3.8m.

Corona SAR Test

  1964-087A


The launch on Dec 21, 1964 was particularly mysterious. Its low orbit led previous analysts to lump it with the CORONA missions, but the orbit was not quite consistent with that assumption, and it was not included in the official list of 145 bona fide CORONA flights.

In 1995 Maj-Gen David Bradburn, former director of USAF Special Projects, reported at a USAF Space History conference that this launch was the first he was in charge of. Minutes before launch, a hold was called because of an approaching train on the line through Vandenberg. However, soon after it was reported that the train had been held up further up the line, and the go was given to resume the count. Washington got two messages in quick succession: `Holding for train' and `Launch!' - and Bradburn got a reputation as the man who launched over the train.

The Vandenberg launch report and launch photo confirm that one SRV was carried and that the orbit attained was close to the one planned. Bradburn stated that the spacecraft operated for four days and completed its mission successfully. He hinted that a couple of further vehicles in the series were cancelled as unneccessary.

The launch was carried out under Program 698BK, which also included the Ferret and NRL multiple launches.

So what was FTV 2355? Clearly it was an experimental rather than an operational mission. The following possibilities came to mind:

  • An NSA electronic intelligence mission to characterize some kind of radio frequency interference or propagation problem. The altitude seems a little low for this, and the recoverable capsule argues against it.

  • A test of an improved camera for a non-CORONA program, such as KH-7.

  • A USAF Program 461 radiometric mission, to provide infrared radiometry data for MIDAS early warning satellites. This was one of the most likely options, but the declassified SAMSO histories of MIDAS do not mention such a mission.

The fact that FTV 2355 was flown under Program 698BK and not Program 241 suggested to me that this was a USAF-sponsored mission rather than a CIA one.

Dwayne Day solved the problem, finding out that the mission was codenamed QUILL and was a test of an active radar (SAR, synthetic aperture radar), based on work done by the University of Michigan's Environmental Research Institute.

The radar data were recorded on tape and returned to Earth via the SRV. The mission was managed by the Air Force (NRO Program A). It was also known as P-40 (possibly Program 40).

In 2012 the program was declassified. It was also known as P-40. The KP-II SAR unit was a modified version of Goodyear's AN/UPQ-102 aircraft-borne pulsed Doppler system with a 0.06 x 0.6 x 4.6m 9.6 GHz SAR antenna flush with the Agena body. The battery powered system was planned for a 4 day mission, and the radar operated on 14 passes over the US (NRO was worried that operating an active radar over the USSR would alert the Soviets). The data was both written to tape for recovery and sent on a UHF data link during ground station pases. The data reached 2.3 meter resolution. QUILL used a Mark VA recovery vehicle, S/N 588, with a TE-236A retro. The TE-236A has a mass of 28 kg full 10 kg dry with an Isp of 260s, burn time of 10s, and DeltaV of 381 m/s.

The first part of the Hawaii pass data with recovery timeline on LMSC Vol 3, page 4-12 appears to be in error by 1000 seconds (separation at 72356s) versus the timeline of page 7-5 (separation at 73356s) which seems to match the orbital data much better.

On insertion Agena 2355 yawed 180 deg to fly tail first. The 126 kg difference between MECO and 'On Orbit' is presumably post-MECO vernier adjustments.

The payload was commanded via the Vandenberg (VTS) and New Hampshire (NHS) tracking stations. Sunnyvale controlled the spacecraft.

Kosmos 2345

 1997-041A


The Kosmos-2345 satellite was launched in Aug 1997. The Proton-K reached a 53 degree parking orbit instead of the usual 51.6 degree one because of a launch crew targeting error. This led to a 50 degree transfer orbit instead of a 46 degree one, and a final elliptical geosynchronous orbit of 34941 x 37747 km instead of a circular one of 35805 x 35917 km. The DM first burn appears to have been on the fifth orbit.

Kosmos-2345 was an Oko-S class satellite, Initial position is 14W with drift to 24W. Space Command seems to have had problems tracking the satellite, with element sets oscillating between an object at 23W and an object at 27W. After early 1999 it tracked an object drifting slowly away from the 25W position, which may or may not have been K-2345.

The DSP 18 satellite was launched by the first Titan 4B in Feb 1997. The Titan 4B placed the IUS/DSP combination in a 185 x 759 km parking orbit, a much higher apogee than earlier launches. The two stage IUS then carried the DSP to geostationary orbit. The craft was stationed at the Indian Ocean position until the end of 2001 when it was moved to a reserve position.
