Kids say the darndest things ...

Postby air.command » Fri Oct 29, 2010 11:49 am

Last night while reading a book about satelites to my 7 year old, he asks me ."Dad what was the first thing people launched into space?" So I explained to him about sputnik, a big silver ball with antennas ... and then he thinks about it and says "wouldn't have the nosecone gone into space first?" ... He had me stumped ... did sputnik's nosecone enter space or did it separate before reaching space?

(I know technically that the V2 reached space first on a suborbital flight. Since we were reading about satellites I didn't want to get sidetracked with orbital and suborbital nuances of spaceflight ... that's for Monday night.) :D

I should know this considering i did an engineering paper involving sputnik last semester, but you to have me stumped.

However, I'm fairly certain that the nosecone did stay with Sputnik all the way into orbit, i vaguely remember one of the other early satellites having a major stability issue because the nosecone didn't detatch correctly upon reaching orbit, thus the satellite was unstable and spun badly.

I may be wrong and standby to be corrected.
...Was it meant to do that?

simple.
if sputnik's nosecone ever entered space in that orbital velocity, it would have made another orbiter around earth other than sputnik itself! may sound crazy, but,...... may be the unseen satellite of the earth!
Where's the apogee....?

I know this is an old thread, but it's an interesting question! In his book "Satellites and Scientific Research" (see: http://www.abebooks.com/servlet/SearchR ... c+Research ), Dr. Desmond King-Hele, the famous orbital analyst for the RAE (Royal Aircraft Establishment, Farnborough) in the UK, tracked all three of the objects placed in orbit by the Sputnik 1 launch on 4 October 1957. These were the satellite itself, the core stage of the R-7 ICBM that injected itself into orbit along with the satellite (this was what most viewers saw, as it was by far the largest and brightest object), and the small nose cap that protected the satellite during ascent, before it was jettisoned in orbit when the satellite separated from the core stage. Also:

Dr. King-Hele (his book "Observing Earth Satellites" [see: http://www.abebooks.com/servlet/SearchR ... Satellites ] is also fascinating!) wrote that the nose cap was very hard to see, and that rather heroic efforts were required to observe and track it. All three objects achieved orbital velocity simultaneously, but the nose cap was the first part to separate, and it was the first (as in "the first in line") of the three objects. Air.command's son's insight serves him well!

I have mentioned these eBooks before: Rockets and People, by Boris Chertok

These are the memoirs of a Russian who started as an electrician and worked his way up to be the control system engineer for the Russian rocketry program. They are a great read:

It is good to get the insights, particularly into the Semyorka ICBM (R7) design and testing. It is still with us today as the Soyuz.

All are enthralling, but Volume 3 (The Cold War) is a bit of a heavy read.

Thank you for the link, OverTheTop! Does the forum have provision for creating "stickies?" (A "sticky" [as in a 'Post-It Note'] is a file containing important information that 'resides' at the top of a forum list; for example, the scale section of "Ye Olde Rocket Forum" has a "sticky" that contains a list of scale data sources [see: http://www.oldrocketforum.com/forumdisplay.php?f=35 ].) Your e-book link below belongs in a space flight/rocketry history "sticky," in a list of recommended books (I'd put Peter Morton's "Fire Across the Desert" and Ivan Southall's "Woomera" in such a "sticky," too.)

Thank you for letting me know, kopius. Which option is it? I see several, but I'm unfamiliar with much of their terminology.
