** Discussing Chinese Satcom Constellations with Lan Tianyi – Dongfang Hour – Chinese aerospace and technology

LAN Tianyi is the CEO of Ultimate Blue Nebula and SpaceKey, two Beijing-based firms focusing on satellite/space industry consulting & research. Having spent several years working inside China’s state-owned space apparatus (largely at CAST and its subsidiaries), Tianyi branched off on his own in 2014, and has since been consulting with many of China’s most successful and dynamic commercial space companies. Today, in addition to his two companies, Tianyi is actively involved in the China Satellite Conference, an annual event in Beijing, as well as Satellite World, a Chinese satellite news publication. On today’s episode, we discuss communications constellations. This year has seen a significant acceleration in the rollout of western low Earth orbit (LEO) communications constellations, with the most obvious example being Starlink. Less publicly, Chinese constellation projects have made steady progress throughout the year, and while we are unlikely to see any Chinese constellation with hundreds of satellites in orbit by year-end, there is much to discuss about these projects.

** Jessy Kate Schingler: Civilization on the Moon — and what it means for life on Earth | TED Talk

We could realistically see people starting to live and work on the Moon in the next decade — and how we do it matters, says space policy researcher Jessy Kate Schingler. In this fascinating talk, she discusses the critical issues that arise when we consider civilization in outer space — such as governance, property rights and resource management — and shows how the Moon can be a template for solving our biggest challenges here on Earth.

Student and amateur CubeSat news roundup – Oct.12.2020

A sampling of recent articles, press releases, etc. related to student and amateur CubeSat / SmallSat projects and programs (find previous smallsat roundups here):

** University of Hawaiʻi student-built Neutron-1 CubeSat reaches the  International Space Station (ISS): UH satellite to collect neutrons in space – University of Hawaiʻi System News

Diagram of the Neutron-1 CubeSat. Credits: Hawaii Space Flight Laboratory (HSFL)

A Northrop Grumman Cygnus cargo vessel berthed to the ISS on October 5th after launching on a Antares rocket from Wallops Island on October 2nd. The Cygnus NG-14 mission carried roughly four tons of cargo, including Neutron-1 and several other smallsats for deployment into orbit from the station. Neutron-1 holds instruments to measure neutrons in space, particularly those coming from the Sun.

Through the 2015 RockSat-X mission, Kauaʻi Community College, Windward Community College, Honolulu Community College and Kapiʻolani Community College were also involved with the development of this mission. The Project IMUA community college collaboration led to the development of a functioning neutron detector, however it was lost during a suborbital test launch from Wallops Flight Facility. This set back the project until Arizona State University (ASU) became a collaborator on this mission by providing the neutron detector in 2018.

“Neutron-1 is a 3U CubeSat [small satellite],” said Amber Imai-Hong, an avionics engineer at HSFL and ground station coordinator for the Neutron-1 mission. “It’s approximately the size of a loaf of bread and the data gathered by the satellite will be used to understand the relationship between the Earth and the Sun by mapping neutrons in the low-earth orbit.”

…

Neutron-1 is launching on a rideshare mission, which includes other satellites, and will be in space for approximately one year. UH delivered the small satellite to NanoRacks, LLC in Houston, Texas on August 20.

** CSFU students developing a satellite to study wildfires: Students Fired Up to Develop Miniature Satellite to Fight Wildfires – Cal State Fullerton Univ. A group of undergraduates at Cal State Fullerton

are designing, manufacturing and building a cube-shaped, miniaturized satellite, known as a CubeSat, to observe Earth from space to predict and detect fires. The data captured is used to detect areas of risk — to put out fires before a blaze even starts.

“This year’s fire season has been particularly harmful. With the onset of climate change, we need to utilize tools such as satellites to study Earth and try to predict and prevent natural disasters,” said senior Patrick Babb, a mechanical engineering major who is leading the team project.

The 10-member student team is developing a prototype, dubbed “TitanSat,” which incorporates infrared cameras and solar power to monitor Earth’s climate and detect hot and dry zones that pose a wildfire risk.

Microsoft’s GSaaS takes a very different approach compared to traditional ground systems. Azure Orbital leverages key technologies such as virtualization, Software-Defined Networking (SDN), and cloud computing to enable customers to automate and scale operations across the globe. On this podcast Nora Zhan, Product Manager for Microsoft discusses Azure Orbital. She is involved in Azure Space, Satellites and Ground Stations and in bringing this new platform to market to provide satellite connectivity.

** The Open Source Satellite Programme – British Computer Society Open Source Specialists

Presented by Paul Madle Over the last 25 years, the UK has brought positive disruptions to the space industry. The University of Surrey innovated small spacecraft: leveraging Commercial-Off-The-Shelf components that could compete with larger more traditionally designed spacecraft. In the last 7 years, Scottish CubeSats (very small satellites) have grown from academic projects into commercially viable products performing earth observation and other applications. Both of these innovations have brought down costs and made space more accessible to greater numbers of people. KIPSE Space Systems aspires to be a catalyst for the next step-change to the industry by collaboratively designing a new, capable spacecraft platform that is open source, all design being freely accessible through the internet.

ESO: Telescopes observe final moments of a star eaten by a black hole

A new report from the European Southern Observatory (ESO):

Death by Spaghettification:
ESO Telescopes Record Last Moments of Star Devoured by a Black Hole

This illustration depicts a star (in the foreground) experiencing spaghettification as it’s sucked in by a supermassive black hole (in the background) during a ‘tidal disruption event’. In a new study, done with the help of ESO’s Very Large Telescope and ESO’s New Technology Telescope, a team of astronomers found that when a black hole devours a star, it can launch a powerful blast of material outwards.Credits ESO

Using telescopes from the European Southern Observatory (ESO) and other organisations around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to date at just over 215 million light-years from Earth, and has been studied in unprecedented detail. The research is published today in Monthly Notices of the Royal Astronomical Society.

“The idea of a black hole ‘sucking in’ a nearby star sounds like science fiction. But this is exactly what happens in a tidal disruption event,”

says Matt Nicholl, a lecturer and Royal Astronomical Society research fellow at the University of Birmingham, UK, and the lead author of the new study. But these tidal disruption events, where a star experiences what’s known as spaghettification as it’s sucked in by a black hole, are rare and not always easy to study. The team of researchers pointed ESO’s Very Large Telescope (VLT) and ESO’s New Technology Telescope (NTT) at a new flash of light that occurred last year close to a supermassive black hole, to investigate in detail what happens when a star is devoured by such a monster.

Astronomers know what should happen in theory.

“When an unlucky star wanders too close to a supermassive black hole in the centre of a galaxy, the extreme gravitational pull of the black hole shreds the star into thin streams of material,”

explains study author Thomas Wevers, an ESO Fellow in Santiago, Chile, who was at the Institute of Astronomy, University of Cambridge, UK, when he conducted the work. As some of the thin strands of stellar material fall into the black hole during this spaghettification process, a bright flare of energy is released, which astronomers can detect.

Although powerful and bright, up to now astronomers have had trouble investigating this burst of light, which is often obscured by a curtain of dust and debris. Only now have astronomers been able to shed light on the origin of this curtain.

“We found that, when a black hole devours a star, it can launch a powerful blast of material outwards that obstructs our view,” 

explains Samantha Oates, also at the University of Birmingham. This happens because the energy released as the black hole eats up stellar material propels the star’s debris outwards.

The discovery was possible because the tidal disruption event the team studied, AT2019qiz, was found just a short time after the star was ripped apart.

“Because we caught it early, we could actually see the curtain of dust and debris being drawn up as the black hole launched a powerful outflow of material with velocities up to 10 000 km/s,” says Kate Alexander, NASA Einstein Fellow at Northwestern University in the US. “This unique ‘peek behind the curtain’ provided the first opportunity to pinpoint the origin of the obscuring material and follow in real time how it engulfs the black hole.”

The team carried out observations of AT2019qiz, located in a spiral galaxy in the constellation of Eridanus, over a 6-month period as the flare grew in luminosity and then faded away.

“Several sky surveys discovered emission from the new tidal disruption event very quickly after the star was ripped apart,” says Wevers. “We immediately pointed a suite of ground-based and space telescopes in that direction to see how the light was produced.”

Multiple observations of the event were taken over the following months with facilities that included X-shooter and EFOSC2, powerful instruments on ESO’s VLT and ESO’s NTT, which are situated in Chile. The prompt and extensive observations in ultraviolet, optical, X-ray and radio light revealed, for the first time, a direct connection between the material flowing out from the star and the bright flare emitted as it is devoured by the black hole.

“The observations showed that the star had roughly the same mass as our own Sun, and that it lost about half of that to the monster black hole, which is over a million times more massive,”

says Nicholl, who is also a visiting researcher at the University of Edinburgh.

The research helps us better understand supermassive black holes and how matter behaves in the extreme gravity environments around them. The team say AT2019qiz could even act as a ‘Rosetta stone’ for interpreting future observations of tidal disruption events. ESO’s Extremely Large Telescope (ELT), planned to start operating this decade, will enable researchers to detect increasingly fainter and faster evolving tidal disruption events, to solve further mysteries of black hole physics.
