Activities 1.Is it necessary and sensible for us to spend 2.a huge amount of money to explore the outer 3.space 2.What do you know about Mars In your opinion,is it possible that there life on Mars Background Information Experimental space exploration dates back to as early as 1912 when the Europeans discovered cosmic rays through balloon flight.In the 1940s USA first observed the Suns UV spectrum and solar x rays.The former USSR sent Sputnik-1,the first artificial satellite,into space in 1957 which marked the advent of mans space exploration era.Sputnik-11.Space Exploration and Mars Survey Background Information In 1958 USA sent Pioneer 0 into Lunar Orbiter.Apollo 11 was the first manned lunar landing,which took place on July 20,1969.Neil A Armstrong and Edward E Aldrin collected 21.7 kilograms of soil and rock samples and deployed experiments.USA launched several manned lunar explorations in the late 1960s and early 1970s.Apollo 17 carried Eugene A Cernan,Harrison H Schmitt,and Ronald B Evans onto the moon on December 12,1972.They became the last persons on the moon.Crew Apollo 111.Space Exploration and Mars Survey 1.Space Exploration and Mars Survey Former USSRs attempts to explore Mars in the earlier 1960s failed.USA began its Mars exploration in 1964.Since then USA has been attempting to know more about Mars and considering sending man onto it.Like Earth,Mars has polar ice caps and clouds in its atmosphere,seasonal weather patterns,volcanoes,canyons and other recognizable features.However,conditions on Mars vary wildly from what we know on our own planet.Background Information Mars1.Space Exploration and Mars Survey Over the past three decades,spacecraft have shown us that Mars is rocky,cold,and sterile beneath its hazy,pink sky.Weve discovered that todays Martian wasteland hints at a formerly volatile world where volcanoes once raged,meteors plowed deep craters,and flash floods rushed over the land.And Mars continues to throw out new enticements with each landing or orbital pass made by spacecrafts.Background Information Volcano on MarsAmong our discoveries about Mars,one stands out above all others:the possible presence of liquid water on Mars,either in its ancient past or preserved in the subsurface today.Water is key because almost everywhere we find water on Earth,we find life.If Mars once had liquid water,or still does today,its compelling to ask whether any microscopic life forms could have developed on its surface.Is there any evidence of life in the planets past If so,could any of these tiny living creatures still exist today Imagine how exciting it would be to answer,“Yes!”Background Information 1.Space Exploration and Mars Survey Even if Mars is devoid of past or present life,however,theres still much excitement on the horizon.We ourselves might become the“life on Mars”should humans choose to travel there one day.Meanwhile,we still have a lot to learn about this amazing planet and its extreme environments.Background Information 1.Space Exploration and Mars Survey Background Information 2.Mars Exploration Rover Mission NASAs twin robot geologists,the Mars Exploration Rovers,launched toward Mars on June 10 and July 7,2003,in search of answers about the history of water on Mars.They landed on Mars January 3 and January 24 PST(January 4 and January 25 UTC).The Mars Exploration Rover mission is part of NASAs Mars Exploration Program,a long-term effort of robotic exploration of the red planet.Primary among the missions scientific goals is to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars.The spacecraft are targeted to sites on opposite sides of Mars that appear to have been affected by liquid water in the past.The landing sites are at Gusev Crater,a possible former lake in a giant impact crater,and Meridiani Planum,where mineral deposits(hematite)suggest Mars had a wet past.Background Information 2.Mars Exploration Rover Mission After the airbag-protected landing craft settle onto the surface and open,the rovers will roll out to take panoramic images.These will give scientists the information they need to select promising geological targets that will tell part of the story of water in Mars past.Then,the rovers will drive to those locations to perform on-site scientific investigations over the course of their 90-day prime mission.Background Information 2.Mars Exploration Rover Mission These are the primary science instruments to be carried by the rovers:Background Information 2.Mars Exploration Rover Mission Panoramic Camera(Pancam):for determining the mineralogy,texture,and structure of the local terrain.Miniature Thermal Emission Spectrometer(Mini-TES):for identifying promising rocks and soils for closer examination and for determining the processes that formed Martian rocks.The instrument will also look skyward to provide temperature profiles of the Martian atmosphere.Mssbauer Spectrometer(MB):for close-up investigations of the mineralogy of iron-bearing rocks and soils.Alpha Particle X-Ray Spectrometer(APXS):for close-up analysis of the abundances of elements that make up rocks and soils.Background Information 2.Mars Exploration Rover Mission Magnets:for collecting magnetic dust particles.The Mssbauer Spectrometer and the Alpha Particle X-ray Spectrometer will analyze the particles collected and help determine the ratio of magnetic particles to non-magnetic particles.They will also analyze the composition of magnetic minerals in airborne dust and rocks that have been ground by the Rock Abrasion Tool.Microscopic Imager(MI):for obtaining close-up,high-resolution images of rocks and soils.Background Information 2.Mars Exploration Rover Mission Rock Abrasion Tool(RAT):for removing dusty and weathered rock surfaces and exposing fresh material for examination by instruments onboard.Before landing,the goal for each rover was to drive up to 40 meters(about 44 yards)in a single day,for a total of up to one 1 kilometer(about three-quarters of a mile).Both goals heve been far exceeded!Background Information 2.Mars Exploration Rover Mission Moving from place to place,the rovers will perform on-site geological investigations.Each rover is sort of the mechanical equivalent of a geologist walking the surface of Mars.The mast-mounted cameras are mounted 1.5 meters(5 feet)high and will provide 360-degree,stereoscopic,humanlike views of the terrain.The robotic arm will be capable of movement in much the same way as a human arm with an elbow and wrist,and will place instruments directly up against rock and soil targets of interest.In the mechanical fist of the arm is a microscopic camera that will serve the same purpose as a geologists handheld magnifying lens.The Rock Abrasion Tool serves the purpose of a geologists rock hammer to expose the insides of rocks.Background Information 2.Mars Exploration Rover Mission 3.Space Shuttle Challenger Disaster-A NASA Tragedy Background Information NASAs Shuttle program was begun in the 1970s,to create reusable craft for transporting cargo into space.Previous space craft could only be used once,then were discarded.The first shuttle,Columbia was launched in 1981.One year later,the Space Shuttle Challenger rolled off the assembly line as the second shuttle of the US fleet.They were followed by Discovery in 1983 and Atlantis in 1985.The Space Shuttle Challenger flew nine successful missions before that fateful day of the disaster in 1986.Explosion of Space Shuttle Challenger Explosion of Space Shuttle Challenger Challenger CrewShuttle mission 51L was much like most other missions.The Challenger was scheduled to carry some cargo,the Tracking Data Relay Satellite-2(TDRS-2),as well as fly the Shuttle-Pointed Tool for Astronomy(SPARTAN-203)/Halleys Comet Experiment Deployable,a free-flying module designed to observe tail and coma of Halleys comet with two ultraviolet spectrometers and two cameras.Background Information 3.Space Shuttle Challenger Disaster-A NASA Tragedy One thing made this mission unique.It was scheduled to be the first flight of a new program called TISP,the Teacher In Space Program.The Challenger was scheduled to carry Sharon Christa McAuliffe,the first teacher to fly in space.Background Information 3.Space Shuttle Challenger Disaster-A NASA Tragedy Selected from among more than 11,000 applicants from the education profession for entrance into the astronaut ranks,McAuliffe was very excited about the opportunity to participate in the space program.I watched the Space Age being born and I would like to participate.Besides McAuliffe,the Challenger crew consisted of mission commander Francis R.Scobee;pilot Michael J.Smith;mission specialists Ronald E.McNair,Ellison S.Onizuka,and Judith A.Resnik;and payload specialists Gregory B.Jarvis.Christa was also listed as a payload specialist.Background Information 3.Space Shuttle Challenger Disaster-A NASA Tragedy From the beginning,though,Shuttle Mission 51L was plagued by problems.Liftoff was initally scheduled from at 3:43 p.m.EST on January 22,1986.It slipped to Jan.23,then Jan.24,due to delays in mission 61-C and finally reset for Jan.25 because of bad weather at transoceanic abort landing(TAL)site in Dakar,Senegal.The launch was again postponed for one day when launch processing was unable to meet new morning liftoff time.Predicted bad weather at Kennedy Space Center(KSC)caused the launch to be rescheduled for 9:37 a.m.EST,Jan.27,but it was delayed another 24 hours when ground servicing equipment hatch closing fixture could not be removed from orbiter hatch.Background Information 3.Space Shuttle Challenger Disaster-A NASA Tragedy The fixture was sawed off and an attaching bolt drilled out before closeout completed.During this delay,the cross winds exceeded limits at KSCs Shuttle Landing Facility.There as a final delay of two hours when a hardware interface module in the launch processing system,which monitors fire detection system,failed during liquid hydrogen tanking procedures.The Challenger finally lifted off at 11:38:00 a.m.EST.Background Information 3.Space Shuttle Challenger Disaster-A NASA Tragedy Seventy three seconds into the mission,the Challenger exploded,killing the entire crew.Language Points1.be up to
