Hubble






Here are some images of an old scratch build I did of a 1/24 scale Hubble Space Telescope. Man I must have built this back in those halcyon days of 96. I couldn't to tell you how accurate this model is to the Hubble back then but it is certainly not accurate to the Hubble now. This was built before computers were common place and all you had to go on were scratchy old photographs and chicken scratch drawings. By gar it's bin a wile. This model was basically built from gift wrap, shampoo bottles a makeup mirror, scrap plastic and a soup can. That's right a soup can. A Campbell's soup can. A Campbell's cream of mushroom soup soup can. But I digress.

From Wikipedia"

The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a space shuttle in 1990. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well-known as both a vital research tool and a public relations boon for astronomy. The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. It is named after the astronomer Edwin Hubble. The HST is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.[5]

Space telescopes were proposed as early as 1923. Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe's most distant objects. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.

Hubble is the only telescope designed to be serviced in space by astronauts. Four servicing missions were performed from 1993 to 2002, but the fifth was canceled on safety grounds following the Space Shuttle Columbia disaster. However, after spirited public discussion, NASA administrator Mike Griffin approved one final servicing mission, completed in 2009. The telescope is now expected to function until at least 2014, when its scientific successor, the James Webb Space Telescope (JWST), is due to be launched.

Wow!

The main thing is that it LOOKS like Hubble and gives the impression of Hubble, and anyone who looks at modern photographs and says "Hey, that access panel is in the wrong spot" should be beaten.

It's a pity there are no 1/24th scale Shuttle kits to team it with!

A long time ago I was going to scratchbuild a lunar rover in 1/24th scale, back when you had to go to a place called a "library" and look at "books" and use a "copy machine" to collect reference material. The project seemed easier back then because nobody really knew what the rover looked like in detail anyway. Now that references are so easy to find, and I can't just "hand-wave" the detailing any more, the project seems a whole lot harder.

Thanks William - You are absolutely correct. Nowadays scratch models also come under much heavier scrutiny then they did back in the day. Back then conjecture and speculation was our friend. Oh well, adopt, adapt and improve as John Cleese would say.
