Ranger 4

Ranger 4 was a spacecraft of the Ranger program designed to transmit pictures of the lunar surface to Earth stations during a period of 10 minutes of flight prior to crashing upon the Moon, to rough-land a seismometer capsule on the Moon, to collect gamma-ray data in flight, to study radar reflectivity of the lunar surface, and to continue testing of the Ranger program for development of lunar and interplanetary spacecraft. An onboard computer failure caused failure of the deployment of the solar panels and navigation systems; as a result the spacecraft crashed on the far side of the Moon without returning any scientific data. It was the first U.S. spacecraft to reach another celestial body.

Spacecraft design

Ranger 4 was a Block II Ranger spacecraft virtually identical to Ranger 3. The basic vehicle was 331 kg (730 lb) 3.1 m (10 ft) high and consisted of a lunar capsule covered with a balsawood impact-limiter, 650 mm (26 in) in diameter, a mono-propellant mid-course motor, a 5080 lbf (22.6 kN) thrust retrorocket, and a gold- and chrome-plated hexagonal base 1.5 m in diameter. A large high-gain dish antenna was attached to the base. Two wing-like solar panels (5.2 m across) were attached to the base and deployed early in the flight. Power was generated by 8680 solar cells contained in the solar panels which charged an 11.5 kg 1 kWh capacity AgZn launching and backup battery. Spacecraft control was provided by a solid-state computer and sequencer and an Earth-controlled command system. Attitude control was provided by Sun and Earth sensors, gyroscopes, and pitch and roll jets. The telemetry system aboard the spacecraft consisted of two 960 MHz transmitters, one at 3 W power output and the other at 50 mW power output, the high-gain antenna, and an omnidirectional antenna. White paint, gold and chrome plating, and a silvered plastic sheet encasing the retrorocket furnished thermal control.

Ranger (magazine)

Ranger was a British comic book magazine, with occasional printed stories, published by Fleetway Publications for 40 un-numbered issues between 18 September 1965 and 18 June 1966. The title was then incorporated into Look and Learn from issue 232, dated 25 June 1966.

The title was created by Leonard Matthews but edited by John Sanders, with Ken Roscoe as assistant editor and Colin Parker as art editor.

Content

The content was a mixture of factual articles, photo features and comic strips designed to appeal to boys.

Nowadays it is best remembered as the birthplace of the science fiction strip The Rise and Fall of the Trigan Empire originally drawn by Don Lawrence which ran continuously from issue 1 of Ranger until the final issue of Look and Learn in 1982.

Other notable comics published in the magazine

  • Rob Riley, drawn by Jesus Blasco (a school story set in Westhaven-on-Sea)
  • Dan Dakota, drawn by Arturo Del Castillo (a Western)
  • Britons Never Never Never Shall Be Slaves (a translation of Asterix from the French magazine Pilote with Asterix renamed Beric and the action moved to Great Britain. In this version (never reprinted), Obelix became the son of Boadicea.
  • Ranger (yacht)

    Ranger was a J-class racing yacht that successfully defended the 1937 America's Cup, defeating the British challenger Endeavour II 4-0 at Newport, Rhode Island. It was the last time J-class yachts would race for the America's Cup.

    Design

    Harold Stirling Vanderbilt funded construction of Ranger, and she was launched on 11 May 1937. She was designed by Starling Burgess and Olin Stephens, and constructed by Bath Iron Works. Stephens would credit Burgess with actually designing Ranger, but the radical departure from the heavy displacement sailing yachts was attributal to Stephens himself who had first used the design in Dorade, winner of the 1931 Trans-Atlantic Race.Geerd Hendel, Burgess's chief draftsman, also had a hand in drawing many of the plans.

    The hull was all steel welded by a shielded arc process with a weight saving aluminum, arc welded, mast counterbalanced with a 110 ton lead keel supported by an arc welded steel keel plate.

    Ranger was constructed according to the Universal Rule that constrained the various dimensions of racing yachts, such as sail area and length. Often referred to as the "super J",Ranger received a rating of 76, the maximum allowed while still adhering to the Universal Rule.
