While MPF will follow a quicker path because it is not going brake in order to go into orbit, but it will land without going into orbit. It is going to arrive on the 4th of July in all ways because it will follow a kind of a straight path so it won't get delayed because its upper stage can be fired longer to speed up its velocity. Thabet Al Fishawi ------------------------ FROM: firstname.lastname@example.org Subject: Challenge Ques -Getting to mars Cc: FWEV79A@PRODIGY.COM Below please find answers to the last challenge question. All answers are from Mr. Vaillancourt's Grade 6 class at Espirito Santo School 143 Everett Street Fall River, MA 02723 Eric Brogan -The MPF takes a shorter curve to Mars while the MGS takes a larger curve. Also the MPF is lighter and the Delta rocket gets more speed. Brian Hudon -The MGP takes a shorter path and the MGS takes a longer path because it cannot handle the stress. Jennifer Novo -There is a time when Mars are Earth are aligned and it will go straight to the planet. Amy Pavao -The MPF takes a shorter way to Mars because Mars is closer to the Earth at that time. Jason Martin -The MGS is following the planet Mars while the MPF is taking a direct route to the planet. -------------- "Terry E. Heeter" Organization: Durkee Elementary School Subject: CHALLENGE QUESTION There are two paths leading to Mars. A slower path and a faster path. The faster path takes more energy to leave the Earth's atmosphere. The MGS will take longer because they used the maximum lift capability of the Delta Rocket. Also, MGS weighs more. The Pathfinder weighs less and is taking the shorter path because of this. Sara Tremeear Grade 6 Durkee Elementary School E-Mail:email@example.com (School) ------------- "Terry E. Heeter" Reply-To: firstname.lastname@example.org Organization: Durkee Elementary School Subject: CHALLENGE QUESTION I want to answer your question about the Mars Pathfinder. There are two paths; one that is a slow path that takes a long time to get there and the faster path that takes a shorter time to get there. The Mars Pathfinder is taking the fast path and the Mars Globel Surveyor is taking the slow path because it is too heavy to go fast. Before they can be launched it has to be 18 months for Earth and Mars can be facing each other. Tonya Evans Grade 6 Durkee Elementary School E-Mail: email@example.com (School) -------------- Cathy Peterson Subject: Challenge Question #6 Cc: firstname.lastname@example.org I think the MPH would reach Mars before the MGS because the launch pad for the MPH is aimed more directly at Mars than the MGS launch pad is. Josie Soto -------- Cathy Peterson Subject: CHALLENGE QUESTION #6 Cc: email@example.com I think that the MGS has more problems getting there than the MPH, and that is why the MGS will take longer to get to Mars. Yamira Diaz ---------- Cathy Peterson Subject: CHALLENGE QUESTION #6 Cc: firstname.lastname@example.org I think the MGS has more power in the rocket boosters than the MPH, and that is why the MGS will get to Mars sooner. Jorge Flores ----------- Cathy Peterson Subject: CHALLENGE QUESTION #6 Cc: email@example.com I think the the MGS weighs less and it would take longer to get to Mars because of the gravity. And the MPH is heavier, so it wouldn't take longer to get to Mars because of the gravity. Joseph Gutierrez --------------- Cathy Peterson Subject: Challenge Question #6 Cc: firstname.lastname@example.org I think that the MGS is lighter than the MPH, so it just floats to Mars while the MPH is heavier so it just makes a straight trip to Mars when it is rocketed. Desmond Clark **Above answers from Cathy Peterson's 5th Grade Students ---------------- Charlotte Stevens Subject: Re: Challenge Question W This answer was written by Dave B, Caroline B. and Paul B. - There is a window every 18 months for a certain amount of time when Earth is closer to Mars. They can use a certain time daily for the liftoff. If it is delayed for more than a week they use a shorter arc...and increase the velocity...with the third stage rocket on the Pathfinder. Charlotte Stevens 8th grade teacher Taylor Road Middle School Alpharetta, Georgia USA ------------------ Dave Grott Subject: Challenge Question #6 Pathfinder will arrive on Mars before Global Surveyor because it is lighter and takes less fuel to launch. It will have fuel left over so it can accelerate or decelerate on its way to Mars. Because it can do that, it can arrive at an exact date. Surveyor is heavier and uses all its fuel just to launch. It will have no fuel left and will 'coast' to Mars. Because it is coasting and will have no fuel to accelerate or decelerate it will take longer to get there. Once it gets there it will be the first craft to use 'aerobraking' to go into orbit around a planet! Mr.Grott's Class Alden Place Elementary School Millbrook, New York 'The ONLY Sixth Grade in the World to Answer all SIX Challenge Questions!!!" -------------------- Gilpin Library Reply-To: email@example.com Organization: Gilpin County School RE-1 CC: firstname.lastname@example.org Subject: CHALLENGE QUESTION The orbit of Mars is an elipse coming closer to Earth during July than during September. Scientists can predict the exact location of Mars making it easier for the MPF to land. MGS on the other hand is father away and can have an eleven-day fudge factor. MGS has to travel farther than MPF therefore taking it longer. The distance to Mars during September is so great that it may take a long time to get there. MPF has a very direct line toward Mars therefore making it easier to predict a date. Josh Venters 12th Grade Chemistry Gilpin County School Black Hawk, Colorado ----------------------------- Edward Beidas Organization: Proviso East H.S. EnergyNet Team Subject: CHALLENGE QUESTION #6 The Mars Pathfinder will arrive on Mars earlier than the Global Surveyor because of the orbits of the Earth and Mars will be closer, and get closer, so the Pathfinder will intercept Mars earlier than the Global Surveyor. It will arrive on July 4 even though it has an uncertain launch date because they know how long it is going to take. They have to wait until Earth and Mars are at a certain distance. FROM PROVISO EAST ------------------------------- From: email@example.com (Tim McCollum) Subject: Challenge Question #6 Because of the weight of MGS and the maximum amount of propellant used in the rocket, it takes a longer and slower path to Mars. The lighter Mars Pathfinder will travel a shorter path to Mars and will therefore arrive earlier. In order to arrive on the 4th of July, regardless of the launch date within its launch window, engineers can simply alter the arc of the path MP travels.
