Untitled[edit]

The BBC "Coast" program showed the satellite being received with a scanner and five-element hand-held Yagi on 137.560MHz. Does anyone know if this is the correct frequency? If so, it would be worth a mention in the article. Emartuk 16:19, 19 September 2007 (UTC)[reply]

It is a PCM downlink frequency that Prospero X-3 used during its active life, but that same frequency has been taken over by the Orbcomm satellites since the 1990s, so the Countryfile event was probably Orbcomm, or a multitude of signals crammed into that band now. --212.62.26.100 (talk) 14:10, 23 February 2015 (UTC)[reply]

Is is a tape recorder on board, or just a player. The text mentions tape recorder, is it used to record anything? —Preceding unsigned comment added by 84.92.211.193 (talk) 13:56, 3 July 2009 (UTC)[reply]

Ariel 1[edit]

The Ariel 1 and Ariel programme articles indicates that Prospero was the fourth British satellite, that Britain was the third rather than the sixth nation to put a satellite into space. I believe that many satellites have been built in Britain, so there are other British satelites also. 92.28.249.93 (talk) 21:27, 18 July 2011 (UTC)[reply]

The article regarding Prospero states;
It was launched at 04:09 GMT on 28 October 1971, from Launch Area 5B (LA-5B) at Woomera, South Australia on a Black Arrow rocket, making Britain the sixth nation to place a satellite into orbit using a domestically developed carrier rocket, after the Soviet Union, United States, France, Japan and China.
So Ariel satellites, launched on American Scout rockets, are irrelevant to the claim. Lots of nations used others to launch their satellites so its not particularly noteworty, relatively few countries however have been capable of putting a satellite into space themselves. Besides even taking the "first national satellite" thing more broadly, only Ariel 3 and after were built by Britain, though operated by the UK Ariel 1 and 2 were US-built.

Construction details?[edit]

I read somewhere (not citeable) that it was built out of spare parts and on a tiny budget. Truth or Fiction?

Citation update[edit]

The last citation to the UCL blog failed with a "Wordpress > Error" (blog has been removed or somesuch). It was available at http://www.archive.today/s3ZV[dead link] though. Not sure how to update that citation to indicate the change, if indeed one should, in line with correct WP policy.

The text is as follows

"Long Overdue Update By Roger J A Duthie, on 4 April 2012 Apologies for the long delay in posts to this blog. We have had a good numbre of people asking about the status of the project, and it’s about time we fessed up to what we’re doing this end. Firstly, not a lot in relation to the Prospero recontact attempt. Though we haven’t given up. Our day jobs have been making pressing demands on our time and the Prospero project has been sidelined as a result. We’ve not been comeplete neglecting it, however. Our custom electronics now has a custom metal box. Previously the circuitry was housed in a cardboard box wrapped in tin foil (very space-age, indeed). Also, we’ve been tackling the problem of the cross-talk we pick up on the Fun Cube Dongle (FCD). The idea of having a filter about the desired (Prospero downlink) frequency on the input wsan’t sufficient. The filter in this case allowed too wide a band and the cross-talk was still apparent in the signal. The new strategy is then to down-shift the frquencies in the signal received, filter it with a robust low-frequency pass-filtere, then up-shift the frequencies before passing it to the FCD. This is still in progress. So, again apologies for the radio silence – we hope to have the filter set up when we have time and have another go at contact soon after." — Preceding unsigned comment added by Pbhj (talk • contribs) 19:00, 20 May 2014 (UTC)[reply]

Recovery attempt[edit]

Was there any update about the recovery mentioned in the article? There was supposedly going to be an update on the 28th but I can’t find any from a google search but it could possibly have been announced somewhere that’s not showing up. DogsRNice (talk) 16:17, 29 October 2021 (UTC)[reply]
