The development of small satellite technologies (SmallSats) has ushered in an era of dynamic and responsive space systems. Hundreds, and soon thousands, of these small platforms will be launched into Low Earth Orbits (LEO) every year. LEO are ideal for Earth Observation missions and other near-earth activities, including internet with global coverage. Approximately half of these SmallSats are projected to be launched into Polar Orbits with the other half orbiting around the equator. According to recent estimates by an SSTL study, close to 1000 SmallSats will be launched annually from 2025 onwards. These satellites will be inserted into new and existing LEO constellations, offering innovative new services to the world while actively limiting the proliferation of space debris in orbits. SmallSats in LEO remain there for less than 3 years before burning up in the Earth's atmosphere. Historically, launch sites have been constructed closer to the equator to support large satellites launches into equatorial orbit. However, direct launch to polar orbit is achieved most efficiently from launch sites nearer the poles, which have minimal interference from aviation and maritime traffic. Southern Launch, founded in 2017, is developing a multi-user launch complex at the tip of the Eyre Peninsula in South Australia, offering a turn-key launch service solution to polar and sun-synchronous orbit. In addition to providing the complete launch infrastructure, Southern Launch has the ability to undertake flight and range safety, vehicle design, avionics componentry and assist with launch permitting and other support services. The year-round temperate weather coupled with the highly skilled local workforce and a robust logistics supply network enables a launch site that offers high cadence launch operations at cost competitive prices. The growing global demand for launch services and a world class launch location has attracted several early investors, with Southern Launch running an oversubscribed seed funding round at the end of 2019 with a larger Series A round to be finalised in coming months. With a highly skilled team drawing on previous experience with the Australian Department of Defence, commercial launch providers, and global infrastructure companies, the Southern Launch team offers unique capabilities to enable safe, secure, and efficient launch operations. Southern Launch have signed a number of agreements with launch service providers and launch vehicle manufacturers from around the world, including companies based in South Korea, Singapore, Germany, USA, Canada, Poland and the Netherlands. While some launch service providers are looking for a launch site for their maiden (test) flights, looking further ahead, all customers have recognized the incredible potential of the Whalers Way location for regular commercial launches, and the cost effective and efficient services offered them by Southern Launch's complete launch service solution. CEO, Southern Launch, Lloyd Damp, says: 'The space industry is in the midst of a rapid transition seeing increasing impact of the private sector providing services to Government agencies such as NASA. Small satellites, in the class of 1 to 500 kg, are a major part of this transition and need suitable locations to be launched from. Our Whalers Way site in South Australia meets this market demand and with the ongoing support from the Australian Space Agency and South Australian Government, we are on track to realise this very real opportunity for Australia.' Construction of the Whaler's Way Orbital Launch Complex is scheduled to be completed ahead of the first launch in 2021, with Southern Launch already contracted for flights.
New electric propulsion chamber explores the future of space travel El Segundo CA (SPX) Jul 09, 2020 Deep inside a laboratory at The Aerospace Corporation's El Segundo campus, scientists are recreating the vacuum of space here on Earth. Aerospace's electric propulsion lab specializes in testing electric thrusters in space-like conditions, and they recently installed a new vacuum chamber that will enable them to test the newer, high-powered thrusters needed for future space exploration. "This chamber adds not just to Aerospace's testing capability, but adds to the world's testing capability, ... read more
