The newest supernova is… • Supernova 1987A
When stars are in a black hole they are squeezed into a point of infinite density. This is called a singularity.
Stars burst when they get too old and can not keep themselves together.
Facts about Early cultures Astrologists named objects in space with names of gods as well as spirits.
They used… • Stonehenges • Gromon- posts in the ground lined to show north, south, east, and west- used by early people that lived in the area of China.
The person that discovered earth orbits the sun is Nicolas Copernicus
The first person to prove the earth rotates is Aristech of Samos in 3rdcentury B.C.
The First person to explain why the sun and stars move across the sky is Copernicus, then Galileo and other people back up his theory.
The first person to developed three laws (on the next slide) regarding planetary motion is Johannes Kepler who made the first two in 1609 and third in 1619.
Those laws are… • The orbit of every planet is an ellipse with the sun at one of the two foci • A line joining a planet and the sun sweeps out equal areas during equal areas during equal intervals of time • The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of itsorbit.

Spirit and opportunity mars rovers October 1, 2007- Spirit and Opportunity entered their fifth mission, that allows the operation of the rovers into 2009, making the rovers to have five years on t Mars surface. August 26, 2008- Opportunity began its three-day climb out of Victoria crater. January 2009- the two rovers had sent back a quarter of a million images and traveled over 20 kilometers. After moving about 3.2 kilometers from Victoria crater, Opportunity first saw the edge of Endeavour crater on March 7, 2009, at Gusev crater, Spirit stuck deep down in the sand.On January 3 and 24,2010 Spirit and Opportunity had been on Mars six years respectively. January 26,2010 after many months of unsuccessful attempts to free the rover from soft sand,NASA announced that Spirit will be used as a S.R.P. March 24, 2010- NASA announced on that Opportunity, drove a distance of 12 km to Endeavour Crater. March 31, 2010- Spirit went into hibernation for the Martian winter and might not run for many months.
Spirit Mars Exploration Rover Spirit drove on Thursday April 24 2009 for the first time since April 8 2009, acting on commands from engineers who are still investigating of amnesia and other unusual behavior exhibited by Spirit in the past two weeks.
The lander, named the Carl Sagan Memorial Station (C.S.M.S.) just after its touchdown on mars, and pathfinder, named Sojourner both outlived their designed lives — the C.S.M.S. by almost three times, and pathfinder by 12 times. From landing until September 27, 1997, the Mars Pathfinder died, returned 2.3 billion bits of information, including more than 16,500 images from C.S.M.S. and 550 images from pathfinder, as well as 15 chemical tests of rocks and soil and info on winds and other weather factors. Findings from the investigations done by scientific instruments on both C.S.M.S. and pathfinder suggest that Mars in the past was warm and wet, with water in its liquid state and a thicker and bigger atmosphere.
Viking 1 Viking 1 orbiter Viking 1 Lander
The orbiter The tools of the orbiter were two video cameras for images, an infrared spectrometer for mapping water and infrared radiometers for thermal mapping. The orbiter mission ended on November 5, 1976. A new mission started on December 14, 1976. Operations included a close approaches to Phobos in February on 1977. On August 7, 1980 The Viking 1 Orbiter was running low gas and its orbit was raised to prevent from crashing into Mars. Operations were stop on August 17, 1980 after 1485 orbits.
The lander The Viking 1 separated from the orbiter on July 20 1976. The aeroshell with its heat shield slowed the craft as it when through the atmosphere. At 6 km above mars, the 160 cm diameter lander parachutes deployed. In 45 seconds the parachute had slowed the lander to 360 m/minute. At 1.5 km above mars, rockets on the lander itself were ignited. The legs had honeycomb aluminum shock absorbers to make the landing softer. The Viking 1 Lander was named the Thomas Mutch Memorial Station (T.M.M.S) The lander operated for 2245 Mars days (about 2306 earth days or 6 years) until November 11, 1982. The viking died when a new software (to improve the lander’s batteries) overwriten the antennas software. Attempts to contact the lander during the next four months, were unsuccessful. In 2006 the Viking 1 lander was found on the Martian surface by the Mars Reconnaissance Orbiter.
Orbiter • The orbiter primary mission ended on October 5, 1976. The extended mission started on 14 December 1976. The orbiter close approaches to Deimos in October 1977. The orbiter developed a leak in its system that lower its attitude control gas. It was placed in a 33,176 km orbit above mars and was turned off on July, 25 1978 after returning almost 16,000 images in about 700–706 orbits around Mars.
Lander The lander separated from the orbiter on 3 September 1976. The Viking 2 Lander touched down about 200 km west of the crater Mie in Utopia Planitia. Approximately 50 lb. of propellants were left at landing. Due to radar misidentification of a rock the thrusters fired an extra time 0.4 second before landing, raising dust. The lander settled down with one leg on a rock. The cameras began taking images immediately after landing. The Viking 2 lander operated on the surface for 1281 Mars days and was turned off (it’s atnnena didn’t fail like viking 1) on April 11, 1980 when its batteries stop working.
