What have been you doing when Chandrayaan-3 created historical past by touchdown close to the south pole of the moon? This is one query that you would possibly maintain encountering all through your lifetime. It is human nature to hyperlink, affiliate and discuss what we as people have been doing when one thing historic pans out.
These issues, nonetheless, are additionally a by-product of how we’re made to really feel a couple of explicit occasion. For even when one thing historic takes place, it may not at all times create waves if there isn’t sufficient hype round it. The profitable launch of the Prospero satellite tv for pc is one such occasion.
The second half of the twentieth Century was an thrilling time within the house race. While the U.S. and the Soviet Union have been on the forefront, the U.Okay. was solely third to them within the area of rocket expertise. Despite having a workable satellite tv for pc launch programme and plans for human-based missions, all of it got here aside for Great Britain in a matter of years.
No fanfare
Britain grew to become the sixth nation to put a satellite tv for pc into orbit with a provider rocket developed indigenously on October 28, 1971. Unlike the frenzy surrounding the success of Chandrayaan-3, there was little fanfare related to it.
Even if we’re to account for the half a century in between and the best way through which information is disseminated with in the present day’s expertise and social media, what occurred with Prospero would nonetheless be discovered wanting. While the American and Soviet house programmes of the time have been being celebrated, Prospero’s profitable launch was a low-key affair.
Black Arrow challenge
Regardless of the way it was acquired, Prospero’s launch was a triumph. The scientists and engineers on the Royal Aircraft Establishment had been concerned with the British house programme from late within the Nineteen Fifties and all their abilities had been invested on this satellite tv for pc.
The Black Arrow rocket programme was a continuation of the U.Okay.’s missile defence programme. The first try and launch a satellite tv for pc (X-2) was a failure in September 1970 because the second stage of the rocket did not pressurise.
With this actually being their final probability, the workforce based mostly on the launch web site in Woomera, Australia did every thing with excessive warning. The Black Arrow rocket was launched on October 28, 1971 from Woomera and inside minutes the Prospero satellite tv for pc, manufactured by the British Aircraft Corporation and Marconi, was positioned efficiently in a polar orbit.
Joy and remorse
The pleasure that the success introduced was blended with disappointment for all these concerned as a result of the British authorities had cancelled the Black Arrow challenge three months earlier owing to escalating prices and funding coming to a standstill. The authorities had agreed upon one remaining launch try which resulted in Prospero’s success.
With the federal government distancing itself from the challenge, there was little concerning the mission for the consumption of the general public. It took two days for the information of the profitable launch to achieve the U.Okay. and even then it didn’t make it to the entrance web page of most newspapers.
Transmits for many years
The 66 kg Prospero was a tiny gadget designed to check techniques for future launches (that by no means took place) and carried a single scientific instrument. While the tape recorders it carried stopped functioning in 1973, Prospero transmitted a sign for over 20 years and continues to orbit the Earth.
Just earlier than the age of the industrial satellites started, the British authorities pulled the plug after having determined that house was largely a waste of cash. Prospero just isn’t solely the primary, however stays thus far the one British satellite tv for pc launched on a British-built rocket.

What’s in a reputation?
Four Black Arrows have been launched between 1969 and 1971. While the primary two have been demonstration flights, X-2 – Britain’s first try and launch a satellite tv for pc – failed to attain orbit because of a difficulty with the stage 2 rocket.
This made Prospero, additionally merely known as X-3 at occasions, the one profitable mission fielded by the Black Arrow challenge.
X-3 underwent a reputation change shortly earlier than launch. It was initially named Puck, the Shakespearean fairy, sprite, or jester who flies world wide with ease in A Midsummer Night’s Dream.
The engineers, nonetheless, felt that a reputation change was so as owing to the circumstances surrounding the launch. They renamed it Prospero after the magician in Shakespeare’s The Tempest who lays down his powers.
