FINAL VERSION Parkes Radio Telescope

 

Parkes Radio Telescope

This telescope is a 64 metre movable radio dish that has operated continuously from 1961 and is one of the most famous radio telescopes in Australia. It has been upgraded to keep up with evolving technology. The reflecting surface has been improved with perforated aluminium; the control system, focus cabin, receivers, computers and cabling have all been replaced. ‘The Dish’ isa film based on this telescope in which cricket is played on top of the dish.

It does not frequently communicate with outer space explorers or missions anymore, leaving those jobs to the observatory in Tidbinbilla. It was a prime receiving station for the Apollo 11 mission in 1969. The video received by this telescope was better than the others at the time as it stood on the best position possible on Earth. The building took three years to design and two years to build. It had the possibility of turning out different to what we see today, but the design that was chosen was good for space exploration and subsequently was copied by NASA when they built other telescopes across the world. The moving dish is said to weigh 1000 tonnes. It stays on all the time but must also allow time for testing and maintenance. The insides look similar to the inside of navy ships due to the builders who built it in the past. There are many ladders and hatches.

Radio waves are a form of electromagnetic radiation and can travel through space all the way to the ground on Earth. This is how the astronauts communicate with Earth and other astronauts in space. At this point, NASA's communications needs are satisfied with the Deep Space Network, Space Network and Near Earth Network. The Deep Space Network is mostly used for receiving signals sent far from Earth towards the ground. This DSN is currently being used for tracking the expedition to Jupiter. It also acts as backup for rare cases when other telescopes run into troubles.

Less usage may be required for the continued operation of this telescope. The cancellation of operations is unlikely, but is possible in the future. Radio telescopes do play a large role in space exploration, but require grouping up with other telescopes (an array) to produce accurate results. This may bring many new discoveries in the future.

Vegetable People Practical

  Year 10 Genetics Experiment- Vegetable People Aim: To produce creative looking vegetable people based on the principles of probability and utilise Pun net squares with purpose. Method: 1.     The genotypes we chose are outlined on the sheet. 2.     We used Punnet squares to work out the possible genotypes and phenotypes of the children. 3.     We tossed a thin eraser to pick the phenotypes of the vegetable children. 4.     After working everything out, the vegetable parents and child were made and photos were taken.

COMPLETED VERSION Charles Perkins and the 1965 Australian Freedom Ride

Image
  Charles Perkins and the 1965 Australian Freedom Ride Charles Perkins was a champion for the rights and justice of Aboriginal and Torres Strait Islanders and an inspirational soccer player. He has described the Freedom Ride as the “the greatest and most exciting event [he had] ever been involved with in Aboriginal affairs”. A re-enactment and celebration of the Ride’s 50 th anniversary was held by the University of Sydney in 2015. That’s just last year. The original campaign was conceived and made possible through the occurrence of the civil rights movement in the U.S in the beginning of the 1960s. The Freedom Riders, as they were called in America, saw effective media coverage but were initially slow to achieve their purpose of desegregation on buses. Despite the violence and unrest it provoked, the tradition of direct action in civil rights was formed and solutions to segregation problems were implemented. Originally, University of Sydney students demonstrating out...
