ISEE 1/2

 1977-102A

---

The ISEE A `Mother' satellite was one of a pair designed to study the magnetosphere. It was launched together with the European Space Agency's ISEE B `daughter' satellite on 1977 Oct 22 at 1353 by a Delta 2914 from Cape Canaveral and received the post launch name International Sun-Earth Explorer 1. The Delta delivered the satellites into a 337 x 137904 km x 29.0 deg orbit. The satellite was still operating when it reentered on 1987 Sep 26.

International Sun-Earth Explorer 2, the ISEE B `Daughter' satellite, was built by STAR/Dornier-Freidrichsafen for the European Space Agency. It was launched on 1977 Oct 22 by a Delta 2914 from Cape Canaveral together with NASA's ISEE 1 satellite. The initial orbit was 341 x 137847 km x 29.0 deg. ISEE 2 was designed to measure magnetospheric and solar wind properties close in space and time to ISEE 1 for comparative purposes. In 1979 Oct its onboard thrusters were used to adjust the orbit and re-approach the ISEE 1 satellite. The perigee increased to a maximum of 3300 km around Jan 1980 and then decreased to 300 km or so around Mar 1982 before increasing again to a new maximum of over 6000 km in early 1985 and decreasing again until reentry. ISEE 2 was still transmitting when it reentered on 1987 Sep 26.

Kosmos 2347

 1997-079A

Kosmos-2337 continued the tradition of annual December US-P launches. It ended operations in late 1999 with no replacement. A small destruct event released 8 tracked objects. RCS was 23m2.

Iridium 38

 1997-069A

---

Delta Iridium MS-5 was launched on 1997 Nov 9, placing a further five satellites in orbit. The MS-5 launch returned to using the higher 625 x 642 km parking orbit, since the satellite was given a lighter fuel load, reducing mass to 662 kg.

Iridium SV038 raised its orbit in late November, but only reached the engineering orbit of 765 km instead of the operational orbit of 780 km. Its orbit was finally raised to operational height in Apr 1998.
