I have a research task on some scientists and was wondering if anyone was willing to mark my responses? Each task is out of 4 and I know I've overwritten for this task because these scientists seriously have so much about them, which is great to learn about but not so great in cutting down
Any help would be super useful, so if there is anyone willing to read it, that'll be amazing!

Outline the work of an Australian Scientist as well as the areas they are currently involved in researching
Elaine Sadler, the Director of the ARC Centre of Excellence for All-sky Astrophysics, is a professor of astrophysics at the University of Sydney, fundamentally evolving astronomy. Analysing both radio and optical telescopes in her work, Sadler has designed and led numerous vital astronomical surveys, including the First Large Absorption Survey in HI project to investigate the distribution of neutral hydrogen gas in distant galaxies. With a team, Sadler also led and developed a radio atlas of the southern hemisphere with Molonglo radio telescopes, and has used the Australian SKA Pathfinder radio telescope to discover a 5 billion year old galaxy. She has completed the first measurement of the cosmic evolution of low power radio galaxies over the past six billion years, detecting that most bright elliptical galaxies have a weak central radio source powered by blackhole accretion. Recently, she identified the optical counterpart of the gamma-ray burst GRB 980425 is a supernova, where the core collapsed to a black hole rather than a neutron star, an incredible contribution to physics.
Sadler currently works with galaxy evolution, how galaxies form and change through cosmic time, and active galaxies, the compact region at the centre of a galaxy with a higher than normal luminosity. She is also investigating low-luminosity radio galaxies, researching the triggers and lifetime in the radio-galaxy phase, and the feedback mechanisms that link the energy output of a galaxy’s central black hole to the star-formation rate.
Discuss the contribution of von Braun to the development of space exploration.
Wernher von Braun, a German aerospace engineer, has made many significant contributions to space exploration, regarding liquid-fuelled propelled rockets, the Jupiter C, Saturn 5 and V2 rocket.
Working with Hermann Oberth, von Braun designed liquid-fuel propelled rockets, which can be combined with greater efficiency and, thus, greater power than the solid-fuel engines. His work controlled the g-forces experienced by astronauts and varied the thrust produced by the rocket, with these liquid fuels now used in modern satellites and in his own Saturn V thrust rocket that powered the Apollo missions.
After defecting, he developed advanced rockets for space exploration, including the Jupiter-C, a modified Redstone ballistic missile that launched the US’s first satellite, Explorer 1, into orbit. Shaping new research and developing space travel, his contributions have enhanced existing knowledge of space exploration. As NASA’s Marshall space flight centre’s director, he later led and constructed the Saturn 5 Rocket, the only space launch vehicle to launch missions that carried humans beyond low Earth orbit. His project also was the booster that launched Apollo 11 into outer space, sending man to the moon and ultimately developing rocket design, fabrication and space travel operation.
However, his role as the director and designer of the V2 rocket, the first intercontinental ballistic missile, had a controversial effect on space exploration. Demonstrating the use of gyroscopes to stabilise large rockets, the V2 was launched 80km above Earth in a 190km trajectory. Its liquid ethanol-oxygen propellent and bullet structure was structured to attack London during World War II, a detriment to rocketry, but was later mimicked in the rockets of the US and Soviet space exploration to launch their space programs .
