Eagle ’69

‘Apollo 11’ was the first lunar-landing mission. Launched on July 16 (1969), the crew of ‘Neil A. Armstrong’, ‘Edwin E. Aldrin, Jr.’, and ‘Michael Allen Collins’ flew the spacecraft ‘Columbia’ (CSM) and ‘Eagle’ (LM). On July 20 (1969), ‘Armstrong’ and ‘Aldrin’ landed the ‘Eagle’ at the relatively flat and unobstructed Tranquillity site on the ‘Moon’, while ‘Collins’ remained in the ‘CSM’.

The ‘LM’ spent 21 hours 36 minutes on the lunar surface, and the crew spent 2 hours 31 minutes outside the ‘LM’ in a local area excursion on foot to a distance of approximately 50 m (160 ft) from Tranquillity Base. ‘Armstrong’ and ‘Aldrin’ evaluated the capability of working on the lunar surface, established a small scientific station, and collected 22 kg (49 lb) of lunar rocks and soil.

Using the descent stage of the ‘LM’ as a launching platform, the ascent stage of the ‘LM’ took off from the ‘Moon’ surface to rendezvous and dock with the ‘CSM’. The spacecraft departed lunar orbit over two days after arrival. This eight-day mission landed and was recovered safely in the ‘Pacific Ocean’. As a precautionary measure, the astronauts were quarantined for 14 days.


Mac 1984

In (1977) ‘Apple’ introduced the ‘Apple II’, a personal computer able to generate color graphics, with its own keyboard, power supply, and eight slots for peripheral devices, which gave users wide possibilities for add-on devices and software programs.

‘Apple’ established its corporate headquarters in ‘Cupertino’ in (1978). The ‘Apple III’ computer, introduced in (1980), sold poorly because of hardware problems and a high price. With ‘Apple II’ sales soaring, in (1982) ‘Apple’ became the first personal-computer company to record annual sales of $1 billion.

In (1983) ‘Apple’ introduced the ‘Lisa’, a personal computer designed for business use that incorporated a handheld mouse to select commands and control an on-screen cursor. The ‘Lisa’ was followed in (1984) by the ‘Macintosh’ personal computer, based on the 68000 microprocessor manufactured by ‘Motorola’. Like the ‘Lisa’, the ‘Macintosh’, also known as the ‘Mac’, incorporated a graphical user interface, which made the computer easy to operate for the novice user.

‘Apple’ entered the office market with the introduction of its ‘LaserWriter’ printer in (1985) and ‘Macintosh Plus’ computer in (1986), a combination that launched the desktop publishing revolution.

Although the company prospered in the early (1980), ‘Wozniak’ left ‘Apple’ in (1985) to start a company of his own. That same year disappointing sales and internal wrangling led to restructuring, the company’s first layoffs, and ‘Jobs’ departure from the company. ‘John Sculley’, whom ‘Jobs’ had hired in (1983) as ‘Apple’ president and chief executive officer, replaced ‘Jobs’ as chairman of the company’s board of directors.
