ASTR 330: The Solar System The class will be partitioned into gatherings of 6-7, in groups. Every group will be required to: Select, from among your homework #6 assignments, one mission plan to present to the class. You may merge components from a few proposition into another proposition. Set up a presentation to the class. No less than two colleagues must present. Presentations ought to take around 3 minutes or less. Space Mission Game! Dr Conor Nixon Fall 2006

Slide 4

ASTR 330: The Solar System The presentation will take the accompanying structure: TITLE - giving mission name, logo, realistic, colleague names. SCIENCE OBJECTIVES - list close to three primary science targets. Say why each is vital. Specialized PLAN - brief portrayal of mission, and rocket particularly instruments (max 5). Portray. Synopsis - persuade the judging board. Presentation materials (pens, transparencies) will be given. You will have around 40 minutes to get ready. Presentations Dr Conor Nixon Fall 2006

Slide 5

ASTR 330: The Solar System One part from every group will volunteer to join a judging board toward the begin of the class. The judging board will devise a scoring rubric and after that evaluate every proposition thusly. Toward the end, they should choose one mission to subsidize! All understudies who partake will get 10 additional credit course focuses. The group which gets the most astounding score will likewise get 5 reward additional credit course focuses. Judging and Scoring Dr Conor Nixon Fall 2006

Slide 6

ASTR 330: The Solar System Final exam: Tuesday December 19 th , 1:30-3:30 pm. Room CSS 2428. Last, most decisive test (120 mins): is 30% of the aggregate course review. Will inspect all material from the entire course. The last test of the year will incorporate numerical issues and in addition expositions. Exams will cover material from BOTH addresses AND course reading. The exam will comprise of an indistinguishable segments from some time recently. Short Answer Questions True/False Statements Longer, organized answer questions. Exams Dr Conor Nixon Fall 2006

Slide 7

ASTR 330: The Solar System Closed-book, no notes or course readings permitted. Bring your own pens and pencils and ruler. Try not to utilize rectification liquid. No talking or other imparting between understudies once the papers are conveyed until they are gathered. Duping will be not go on without serious consequences. On the off chance that you are seen/heard to cheat you might be requested that leave the exam room, and the case instantly alluded to the Head of Classes in the Astronomy Department. You will lose all credit for the exam and your case might be alluded to the University level. Exam lead Dr Conor Nixon Fall 2006

Slide 8

ASTR 330: The Solar System Write a brief meaning of the accompanying terms and ideas, and give a case from the course: Greenhouse impact. Separation. Doppler impact. Ejecta cover. Retrograde circle. Case short answer address Dr Conor Nixon Fall 2006

Slide 9

ASTR 330: The Solar System Life in the Solar System. Circle the letter for each right reply, cross out the letter for each wrong reply. At that point, for the wrong replies, cross out part of the announcement which is erroneous and add substitution content to make the sentence a genuine, positive articulation. A) The two primary attributes of a living being are digestion system and generation. B) The last regular progenitor (LCA) is the guessed primate which offered ascend to both chimps and people. C) Amino acids have as of late been found in space which is proof of life. Case True/False Question Dr Conor Nixon Fall 2006

Slide 10

ASTR 330: The Solar System D) Water ice has been found in the polar tops of Mars. Likewise, fluid water once existed on the surface of Mars, where we trust that conditions may once have been ideal for life to emerge. E) Massive effects were a noteworthy issue for life on Earth previously, perhaps in charge of mass eliminations, (for example, the dinosaurs). In any case, at the present day we don\'t have anything to fear from them. Genuine/False proceeded with Dr Conor Nixon Fall 2006

Slide 11

ASTR 330: The Solar System All four of the external gas monster planets have ring frameworks. Portray the A, B and C rings of Saturn. Say which is the most and minimum splendid, and what the rings are made of. The F-ring is a weird thin ring found by the Voyager rocket. Why does it not spread out and vanish? Are there similitudes between this ring and the rings of Uranus and Neptune? Clarify. The rings of Uranus and Neptune are likely made out of an alternate material than a large portion of the Saturn ring particles. Say what the distinctions are, and hypotheses we need to represent this distinction. Illustration Structured Question Dr Conor Nixon Fall 2006

Slide 13

ASTR 330: The Solar System No dialog of the planetary framework would be finished without looking at the innovation which provided the majority of our data about the planets: mechanical shuttle . Until the twentieth century , planetary review was restricted to telescope space science : a \'hands-off\' method for investigation which constrained us to recording what the skies needed to show us. For instance, consider the furthest side of the Moon. 45% of the Moon was inconspicuous until the main rocket was sent there ( Luna 3, 1959 ). With the coming of expansive fluid powered rockets joined with electronic circuits , sending tests outside the Earth\'s circle at long last got to be distinctly conceivable. Unmanned art started things out, took after not long after by kept an eye on spaceships. Be that as it may, in this way, people have just achieved the Moon, not yet wandering past the Earth\'s gravitational draw. Rocket Dr Conor Nixon Fall 2006

Slide 14

ASTR 330: The Solar System Spacecraft missions comprehensively can be categorized as one of the accompanying classifications: Space Telescopes Fly-by missions Orbiter missions Atmospheric tests (not intended to arrive). Hard and delicate landers Rovers. Cross breed/composite missions. We will talk about every sort thusly, aside from #1, which are more like the Earth-based telescopes examined in Lecture 5. Sorts of Spacecraft Missions Dr Conor Nixon Fall 2006

Slide 15

ASTR 330: The Solar System Fly-by missions are dependably the primary scouts sent to a planet, on a fundamental surveillance task. They are assembled inexpensively with a couple of fundamental instruments to gauge attractive field properties and picture the surface, preparing for some other time, more competent orbiters and landers. It is difficult to outline an effective orbiter, not to mention a lander, without essential learning of planet gave by fly-by missions. We will talk about some well known automated fly-bys, yet take note of that Apollo 8 was additionally popular as the initially kept an eye on fly-by mission of a different universe (the Moon). Fly-by missions Dr Conor Nixon Fall 2006

Slide 16

ASTR 330: The Solar System By far the most understood and pivotal fly-by missions ever were the twin Voyager 1 & 2 shuttle, talked about in detail before in the course. Truth be told, Pioneers10 & 11 had as of now achieved Jupiter (and Saturn for Pioneer 11). The Voyager missions were well known for accomplishing the fabulous visit: the different flybys of each of the four gas goliath planets that was accomplished by Voyager 2 .

Slide 17

ASTR 330: The Solar System Orbiter missions take after on from fly-by missions. Their motivation is for the most part to acquire an intensive mapping of the planetary surface, for the most part in obvious light , albeit now and then radar must be utilized. The perfect circle for this is a polar circle , disregarding both posts, and mapping the planet as a pivots underneath each orbital track - this is regularly utilized for the Earth. For planetary missions anyway, it is frequently excessively troublesome or costly, making it impossible to achieve a polar circle, so orbiters are in central or low-slant circles. Orbiter missions Dr Conor Nixon Fall 2006

Slide 18

ASTR 330: The Solar System Venus represents a harder issue for mapping than the Moon or Mars - why? Because of the thick, overcast climate, mapping in unmistakable light won\'t se to the surface - radar must be utilized. The best ever surface guide of Venus was made by the Magellan shuttle (craftsman\'s impression, right), which utilized a propelled type of radar called \'manufactured opening radar\' (SAR) to delineate whole planet down to 100 m determination. The undertaking took 2 years, from 1990-1992 , and Magellan at long last returned a bigger number of information than every past mission joined!

Slide 19

ASTR 330: The Solar System Atmospheric tests were not significant to the investigation of the Moon or Mars , however particularly for Venus there were numerous climatic tests (endeavored landers generally) before a genuine landing was accomplished. In the external close planetary system, Galileo conveyed a test (no name) which was dropped into Jupiter\'s air, giving back the first in situ meas
