The Castor-Orbus was a Castor 4 sounding rocket (research rocket designed to take measurements and perform scientific experiments during its flight) that was developed in 1992 by the Orbital Sciences Corporation (OSC) (United States). Launched three times in its five-year-long career from 1992 to 1997, the Castor-Orbus rocket launched successfully only once. It was first launched on October 16, 1992, while its final launch took place on October 4, 1997.

Contents

There were two Castor-Orbus models made, Castor-Orbus and Castor-Orbus 1.

Advanced details

Weighing 13.5  tons (13,500 kilograms), the Castor-Orbus had a lift-off thrust of approximately 430  kilonewtons (equivalent to around 96,660  lbf). The rocket had a core diameter measuring 1.02 metres (3.34 feet), with a total length of exactly 16 metres (52 ft). It had an apsis (apogee) of over 500 kilometres (310 mi). The family of the Castor-Orbus rocket was Castor 4, which was partially responsible for the Castor-Orbus naming. Castor IVA, a straight nozzle version of the same motor used for the Delta launch vehicle built by Thiokol Corp, was stage 1. Stage 2 consisted of a United Technologies Corp Orbus 1 space motor. Thus the pairing of the Castor-Orbus motors for the BP-TLV and BP-1M.

Career

The Castor-Orbus rocket was launched three times over almost five years. After the launch of October 4, 1997, the Castor-Orbus was dropped from service.

Delta II was an expendable launch system, originally designed and built by McDonnell Douglas, and sometimes known as the Thorad Delta 1. Delta II was part of the Delta rocket family and entered service in 1989. Delta II vehicles included the Delta 6000, and the two later Delta 7000 variants. The rocket flew its final mission ICESat-2 on 15 September 2018, earning the launch vehicle a streak of 100 successful missions in a row, with the last failure being GPS IIR-1 in 1997.

<span class="mw-page-title-main">Boilerplate (spaceflight)</span> Nonfunctional spacecraft or payload

A boilerplate spacecraft, also known as a mass simulator, is a nonfunctional craft or payload that is used to test various configurations and basic size, load, and handling characteristics of rocket launch vehicles. It is far less expensive to build multiple, full-scale, non-functional boilerplate spacecraft than it is to develop the full system. In this way, boilerplate spacecraft allow components and aspects of cutting-edge aerospace projects to be tested while detailed contracts for the final project are being negotiated. These tests may be used to develop procedures for mating a spacecraft to its launch vehicle, emergency access and egress, maintenance support activities, and various transportation processes.

The Saturn V dynamic test vehicle, designated SA-500D, is a prototype Saturn V rocket used by NASA to test the performance of the rocket when vibrated to simulate the shaking which subsequent rockets would experience during launch. It was the first full-scale Saturn V completed by the Marshall Space Flight Center (MSFC). Though SA-500D never flew, it was instrumental in the development of the Saturn V rocket which propelled the first men to the Moon as part of the Apollo program. Built under the direction of Dr. Wernher von Braun, it served as the test vehicle for all of the Saturn support facilities at MSFC.

<span class="mw-page-title-main">Solid Rocket Motor Upgrade</span> American solid propellant rocket motor

The Solid Rocket Motor Upgrade (SRMU) was a solid rocket motor that was used as a booster on the Titan IVB launch vehicle. Developed by Hercules, it was intended to be a high-performance, low-cost upgrade to the UA1207 boosters previously used on Titan IV. Wound from carbon-fibre-reinforced polymer and burning a hydroxyl-terminated polybutadiene-bound ammonium perchlorate composite propellant, it was an ambitious upgrade building on Hercules' experience developing a filament-wound case for the Space Shuttle SRB. Originally intended to fly in 1990, it instead first flew in 1997 due to a protracted development and lack of demand. The SRMU performed successfully on all of its flights.
