Intelsat 603

 1990-021A

---

Intelsat 603 was the first single-payload launch aboard a Commercial Titan 3. Martin Marietta failed to rewire the logic to take into account the fact that no dual-launch `top' satellite was present; the Intelsat and its Orbus 21S perigee kick motor remained attached to the Titan core second stage, waiting in vain for the non-existent top satellite to separate. Controllers commanded the Intelsat to separate from its kick motor, and used the liquid apogee motor to raise the satellite's orbit and avoid an early reentry. The Titan stage reentered on Mar 28 at 1420 UTC, over the Pacific southeast of Taiwan.

In 2003 usage of IS-603 was transferred to New Skies (although it's not clear if ownership changed). An on orbit operations licence was given to Intelsat Global/UK by the UK government on 2010 Nov 17; on 2013 Jan 8 the satellite's control was transferred to Argentina to provide ARSAT service at 81W.

WMAP

 2001-027A

---

The Microwave Anisotropy Probe is a MIDEX mission launched by Delta 7425-10 to the Earth-Sun L2 point. 3 month transit to L2 with lunar flybys.

The satellite observes from 22 to 90 GHz with a resolution of 13-55 arcmin. Mass 837 kg full, incuding 72 kg prop.

Box 3.8 h 2.0w? 5.0 span with a circular deployable solar array/thermal shield panel. GSFC mission and GSFC-built spacecraft. The instrument was built in collaboration with Princeton.

A slight SES-1 overburn was required to achieve the desired parking orbit.

In Feb 2003 MAP was renamed WMAP, the Wilkinson Microwave Anisotropy Probe, after David T. Wilkinson (1935-2002), one of the leaders of the COBE and MAP satellite programs. The WMAP team announced their preliminary results at the same time, with values of the Hubble Constant, the age of the universe, the breakdown of baryonic matter, dark matter and dark energy, and the first measurement of the time of reionization.

Close passes (less than 10 million km) to the Earth are predicted in Apr 2025 and Nov 2039.

DigitalGlobe's QuickBird made it to orbit safely. Planned orbit was lowered to beat Ikonos' resolution and achieve 0.6m. Mass is 1028 kg.

In 2011 the orbit was boosted to 475 km and then allowed to decay until its 2015 reentry.
