TheDelta 5000 series was an Americanexpendable launch system which was used to conduct anorbital launch in 1989. It was a member of theDelta family of rockets. Although several variants were put forward, only the Delta 5920 was launched. The designation used afour digit numerical code to store information on the configuration of the rocket. It was built from a combination of spare parts left over from earlier Delta rockets, which were being retired, and parts from theDelta II 6000-series, which was just entering service.

The first stage was theRS-27 poweredExtended Long Tank Thor, flown on several earlier Delta rockets. NineCastor-4A solid rocket boosters were attached to increase thrust at lift-off, replacing the less powerfulCastor-4 boosters used on the 3000 series. TheDelta-K was used as a second stage. In the configuration that was launched, no third stage was flown.

The Delta 5000 was launched just once, fromSpace Launch Complex 2W at theVandenberg Air Force Base. Launch occurred at 14:34 on 18 November 1989. It was successful, and placed theCosmic Background Explorer (COBE) spacecraft intolow Earth orbit.^[2]^[3]

Payload

[edit]

This section is an excerpt fromCosmic Background Explorer.[edit]

TheCosmic Background Explorer (COBE/ˈkoʊbi/KOH-bee), also referred to as Explorer 66, was aNASA satellite dedicated tocosmology, which operated from 1989 to 1993. Its goals were to investigate thecosmic microwave background radiation (CMB or CMBR) of theuniverse and provide measurements that would help shape the understanding of thecosmos.

COBE's measurements provided two key pieces of evidence that supported theBig Bang theory of the universe: that the CMB has a near-perfectblack-body spectrum, and that it has very faintanisotropies. Two of COBE's principal investigators,George F. Smoot III andJohn C. Mather, received theNobel Prize in Physics in 2006 for their work on the project. According to the Nobel Prize committee, "the COBE project can also be regarded as the starting point forcosmology as a precision science".^[4]

COBE was the second cosmic microwave background satellite, followingRELIKT-1, and was followed by two more advanced spacecraft: theWilkinson Microwave Anisotropy Probe (WMAP) operated from 2001 to 2010 and thePlanck spacecraft from 2009 to 2013.
