Great job to all of you! Thanks to all for entering their answers! ANSWERS from Participants: " the Greek letter is Delta the Fourth letter in Greek Alphabet which is similar to the " D" in English but it is written in Greek like a small triangle , well its relation to Nasa's launches to Mars is that the rocket which will carry all Mars missions is Called also Delta , this 121 feet high rocket , consists of 3 stages and it is the new edition of the military missile called Thor . And it was chosen by Nasa because it holds best safety record for all unmanned-payload rockets . As Souyz Launching rocket holds the best record for manned-payload launch . And it is also used in getting to Mars because its third stage give the spacecraft a boost in a path which ends near Mars , then the spacecraft is separated and by its small engine and thrusters it makes some correction maneuvers to make its path ends exactly at Mars , then many small maneuvers are done to make the spacecraft ready to land at its desired landing area as the Global surveyor landers don't go into orbits as their interplantery path ends at the upper layeres of Mars Atmosphere so they have to be near their landing site so just to descent and land ] this is done to prevent the third stage from crashing on Mars , and polluting it ! [Planetary red-tape that's it !! ] Thabet ----------- The letter that is important is Delta. Both the Mars Global Surveyor and the Mars Pathfinder were launched to Mars on a Delta 2 Rocket. Answered by, Stephanie Wong ---------- "Linda Lund" Organization: REDEEMING LOVE CHRISTIAN CENTER The 8th Grade Class of Love Christian Academy 13 and 14 year olds The greek Letter is delta. Both the Surveyor and Pathfinder probes traveled on a Delta Rocket. ----------------- From: Robert Gillmor Answer: Delta DeltaV 10 is the force required to leave the gravity well that is the Earth -------------- AMERIDIOMA*JMAM The greek letter is gamma, because of the solar flares that the sun has been having. This causes a higher radiation than normal, especially increasing the gamma rays, that interfere with the electronic equipment both on Earth and on the probe to Mars. Thank you, Alex -------------- AMERIDIOMA*JMAM I figure that the greek letter is alpha, cause of it being the first. This mission is the first of its kind, to go to Mars, for the USA to be FIRST. Thank you, Patricia Alvarado -------------- From: Provo Dixon Middle School Mesa Class The Greek letter used in launching the missions and helping to get there would be the Greek letter " Delta". The name of the rocket used in launching is Delta and then the formula " Delta V" is used to correct the speed and/or direction of the missions going to Mars. Delta is the algebraic term meaning "change".
