Alice & Jemma Meerkat
The document discusses the MeerKAT radio telescope project in South Africa. It describes how radio telescopes can observe radio waves from distant stars and galaxies to see back in time, and how the MeerKAT array involves building 64 radio telescopes to work together as a single large instrument. It also mentions that the MeerKAT project is a precursor to the larger $20 billion SKA radio telescope project which will be constructed in Africa and Australia through 2024 and involve 100 young scientists.
The meer kat project
The Square Kilometre Array (SKA) will be the world's largest radio telescope, built primarily in South Africa and Australia. It aims to advance understanding of star and galaxy formation by detecting radio waves from space. Most of the SKA will be constructed in South Africa, with the core site located in the Northern Cape Province where the MeerKAT telescope is currently serving as a tester for the larger SKA project. Once completed in 2024, the SKA will be extremely sensitive and able to detect radio signals from distant planets and galaxies.
The meerkat project
The meerKAT project is testing technology for the larger SKA project which plans to create an array of 64 very large radio telescopes to be over 50 times more powerful and 10,000 times faster than any existing radio telescope. It has involved over 100 scientists and engineers from 13 countries donating over 20 billion Rand and input from 100 organizations over many years of hard work with more contributors constantly joining.
Space future
The document discusses plans for building a space elevator to provide cheaper access to space. It proposes constructing an initial 20 ton capacity elevator using existing or near-term technologies like carbon nanotubes. The elevator would use climbers powered by solar panels to transport payloads at a low cost of $250/kg to various orbits and destinations in space. Some challenges include developing strong and lightweight tether materials, but advantages are low operations costs, no launch vibrations, and safe space access without rockets.
Infrared telescopes kel, jesse, ela, ellie
An infrared telescope detects celestial bodies using infrared light. It allows scientists to measure temperatures of planets, stars, and dust, and see past dust clouds. Infrared telescopes function using components like helium, solar shields, and detectors. They have advantages like viewing farther than visible light and penetrating dust clouds, but use large amounts of helium and require detectors that take up space. Examples given are the Spitzer and Hubble telescopes.
Failure the-good-parts
This document discusses software failures and strategies for handling them. It begins by providing examples of high-profile failures, such as the Ariane 5 rocket explosion caused by a data type conversion error. It then discusses different types of failures that can occur at the runtime, hardware, and human levels. The document emphasizes that failure management is important and provides techniques like defensive programming, circuit breakers, supervision, bulkheading, and graceful degradation to prevent failures from cascading. It concludes by arguing that failure handling need not be boring and should be a core part of building reliable distributed systems.

WHAT IS SPACE DEBRIS????
Space debris refers to non-functional human-made objects in space including defunct satellites, spent rocket stages, and other fragments. The amount of space debris has grown significantly over the past 50 years as space activity has increased. There are now over 25,000 pieces large enough to track that orbit the Earth. Collisions with space debris pose risks to both operational satellites and human spaceflight through damage. Potential solutions to the growing problem include deorbiting satellites at end of life, moving them to graveyard orbits, using tethers to remove objects, and developing active debris removal technologies. International cooperation will be needed to address this issue and ensure the future sustainability and safety of space activities.
Astronomy - State of the Art - Telescopes
Telescopes help us learn about the universe by collecting more light than the human eye and seeing more detail. Larger telescopes collect more light and see sharper images, but the atmosphere limits ground-based telescope resolution. Telescope size has grown exponentially over time. Adaptive optics and interferometry allow telescopes to approach the theoretical resolution limit. While space telescopes avoid many atmospheric limitations, they are much more expensive to build and operate. The Hubble Space Telescope has revolutionized astronomy through high-quality images across the electromagnetic spectrum.
