SPACE2081 [3.5/3.0] Launch Window Mystery Cache

This cache has been archived.

OReviewer: As there's been no response to my earlier note, I am forced to archive this listing.

If you wish to repair/replace the cache sometime in the future, just contact me email, including the GC Code, and assuming it meets the guidelines, we'll be happy to unarchive it.

Thanks,

Geocache Description:

Will you make your Launch Window and find this cache?


This Cache:

THE POSTED COORDINATES ARE USELESS!

A launch window is a term used in spaceflight to describe a time period in which a particular launch vehicle (rocket, Space Shuttle, etc.) must be launched. If the rocket does not launch within the "window", it has to wait for the next window.

For trips into largely arbitrary Earth orbits, almost any time will do. But if the spacecraft intends to rendezvous with a space station (such as the International Space Station) or another vehicle already in an orbit, the launch must be carefully timed to occur around the times that the target vehicle's orbital plane intersects the launch site.

For launches above low Earth orbit (LEO), the actual launch time can be somewhat flexible if a parking orbit is used, because the inclination and time the spacecraft initially spends in the parking orbit can be varied. See the launch window used by the Mars Global Surveyor spacecraft to the planet Mars here.


To go to another planet using the simple low-energy Hohmann transfer orbit, if eccentricity of orbits is not a factor, launch windows are periodic according to the synodic period; for example, in the case of Mars the period is 2.135 years, i.e. 780 days. In more complex cases, including the use of gravitational slingshots, launch windows are irregular. Sometimes rare opportunities arise such as when Voyager 2 took advantage of a 175 year planetary alignment (launch window) to visit Jupiter, Saturn, Uranus and Neptune. When such an opportunity is missed, another target may be selected. For example, the Rosetta mission of ESA was originally intended for comet 46P/Wirtanen, but a launcher problem delayed it and a new target had to be selected (comet 67P/Churyumov-Gerasimenko). -From Wikipedia


Regardless of how it looks, bushwhacking is NOT required. The terrain may be lower depending on the season and recent weather.


This Series:

This cache is part of the SPACE 2081: A Geocaching Odyssey challenge.

This challenge contains one cache of each difficulty and terrain combination, plus a final cache which can be found only after finding all 81 caches that are part of the series. Each of those 81 caches will contain a code, which you will use as part of the puzzle to solve the FINAL CACHE.

All the members of the space team are actual cachers who are remaining anonymous for the moment. You can find more info on the series, as well as a complete list of released caches HERE. Please do not post hints or spoilers in your logs. Also, each cache must be signed by any individual cachers going for the final.

Good luck, may the force be with you, live long and prosper.
