DCUBED’s release actuators will fly on LuxSpace’s Triton-X

February 9, 2023 by editorial

Triton-X is LuxSpace’s ultimate platform for micro- to mini- LEO smallsat systems.
Designed as “multi-purpose” cost-effective products, the scalable and powerful Triton-X platforms are easily adaptable to various typologies of LEO missions and payloads, also in small and/or hybrid constellations.

DCUBED’s new line of release actuators Micro Pin Puller and Micro Release Nut will fly aboard LuxSpace’s multipurpose small-satellite platform Triton-X on the upcoming Genesis mission.

The Triton-X Genesis project is the first step in the roll-out of the Triton-X platform, a multi-mission product providing high on-board processing power and scalable in the 50-250 kg range.

Later last year, LuxSpace sold a Triton-X Heavy satellite for the Seranis project of the University of the German Bundeswehr, leveraging 15+ years of Space systems design, manufacturing, and in-orbit delivery.

DCUBED and LuxSpace share the goal of enabling missions to take their capabilities to the next level and look forward to demonstrating their new technologies with their upcoming mission.

DCUBED’s CEO Thomas Sinn in Germering (Bavaria, Germany) can assist with COTS release actuators and COTS deployables that are specifically designed for SmallSat applications. DCUBED’s pin puller and release nut actuators are space-proven, readily available, easy to use, and small in size. The DCUBED SmallSat deployables (Space Selfie Stick, 100W 1U solar array and deployable radiator) tackle the needs of new space customers by maximizing performance in space while remaining efficiently packed in a standardised volume for launch. 

LuxSpace (CEO Edgar Milic) was established in Luxembourg in 2004 as a subsidiary of OHB SE and is an integrated provider of small satellites and space-based applications and services. The company can look back on seven successfully launched space systems, including the Triton-2/ESAIL satellite launched , and has over 16 years of experience in data applications with a particular focus on the maritime sector and Earth observation.

Africa’s critical mineral exploration rapidly accelerates as Fleet Space deploys the first ExoSphere satellite

January 13, 2023 by editorial

Fleet Space announces the first deployment of its ExoSphere satellite-based mineral exploration system in Africa, in a new partnership with Resonance Frequency Exploration Group (RFEG), based in the USA with operations in Accra, Ghana. Under a licensing and technology cooperation agreement finalized in December 2022, Fleet Space will supply its Geode portable sensors, which use Ambient Noise Tomography (ANT) to collect subsurface data. This data is then beamed to the ExoSphere constellation of Low Earth Orbit (LEO) satellites and then relayed to computers that use intelligent data processing to generate detailed 3D subsurface maps. Unlike traditional prospecting methods that can take months or years to complete, the whole process takes only days or weeks. 

Adelaide, South Australia; Flavia Tata Nardini, CEO and Co-Founder, Fleet Space Technologies stated, “There is an urgent, global need to discover new sources of critical minerals to support the transition to clean energy and net-zero. Building on our existing successful partnerships in Australia and North America, we’re delighted that our ExoSphere system is now being deployed on mineral exploration projects in Africa for the first time. Through this pioneering licensing and technology cooperation agreement, ExoSphere will give our partners at RFEG access to our Ambient Noise Tomography (ANT) and real-time processing capabilities to complement their own proprietary systems. Together, we can greatly speed up the exploration process for a range of vital minerals, while also massively reducing its environmental impact — a win-win for Ghana and the wider international response to climate change.”

ExoSphere brings a powerful new dimension to the ongoing Mineral Resource Estimate projects RFEG is conducting, in particular in the Oti Region of Ghana. Under the auspices of the Ghana Geological Survey Authority (GGSA), with implementation by RFEG’s team, ExoSphere will complement RFEG’s own XPLR remote-sensing mapping-analysis technology. This is achieved by cross-referencing the data from both sources, thereby significantly increasing the likelihood of finding new mineral deposits more quickly and with much greater accuracy. 

ExoSphere’s Geodes are light enough to be carried by one team member, making them ideal for use in challenging and inaccessible terrain. They are also entirely non-invasive, eliminating the need for explosives or vibrating trucks to collect subsurface seismic data. This substantially reduces costs, logistical issues and environmental disturbance; the accuracy of the combined data collection and analysis by Exosphere and RFEG’s systems also means, for mining operators, that drilling can be streamlined to areas where considerable deposits are known to exist. 

RFEG selected Fleet Space as its technical partner after a worldwide search. The company is seeking to help current and prospective clients in the USA, Africa, Central and South America take a more tech-forward, eco-conscious approach to better ascertain site viability and increase operating efficiencies. In particular, it is focusing on using satellite-based image processing technologies analyzed by proprietary algorithms to determine a prospective site’s viability before embarking on traditional geophysical work. RFEG founder Schad Brannon said, “The addition of ExoSphere 3D rendering of subsurface topography by Fleet Space propels the XPLR technology product suite and technology-stack to the next level by creating the most comprehensive satellite-based remote sensing survey product available within the mineral exploration marketplace to date”.     

Fleet Space founder Flavia Tata Nardini says, “We’re incredibly excited to see ExoSphere being deployed in Africa, and to be working in partnership with RFEG. Our two organizations have much in common: we’re both looking to make mineral exploration faster and more efficient through technology; we’re explorers and pioneers developing that technology ourselves; and we’re absolutely committed to reducing the environmental impact of these activities, which are fundamental to economic development and climate action.”

Virgin Orbit reports all systems are ‘green’ for the first historic UK launch

January 8, 2023 by editorial

Partners for the United Kingdom’s first orbital launch announced that the initial window for the historic Start Me Up mission will officially open on Monday, January 9th at 22:16, UTC, with additional back-up dates continuing into mid- and late January — Start Me Up is a collaborative effort between the United Kingdom Space Agency (UKSA), Cornwall Council, the Royal Air Force (RAF St Mawgan), and Virgin Orbit (Nasdaq: VORB).

The Start Me Up mission will carry satellites from seven customers to space, including commercial and government payloads from several nations as well as a collaborative US-UK mission.

The LauncherOne system that will conduct the mission is now mated to its carrier aircraft, a Boeing 747 dubbed Cosmic Girl, at Spaceport Cornwall. Virgin Orbit’s LauncherOne system successfully completed an end-to-end launch rehearsal, taking the integrated system through to the loading of propellants and proceeding through terminal count, resulting in the verification of the health of the system and readiness of the team.

Given the number of “firsts” being executed for this launch – the first orbital launch from UK soil or from anywhere in western Europe — Virgin Orbit and its partners will maintain a conservative posture with regard to system health, weather and all other elements of scheduling.

Spaceport Cornwall received the United Kingdom’s first spaceport license from the UK Civil Aviation Authority (CAA) in November of 2022. In late December of 2022, Virgin Orbit was issued first-of-their-kind launch and range control licenses, which ensured all regulatory, safety, and environmental requirements have been met. This week, the CAA announced that all of the satellites flying on this mission have received their licenses as well.

An aerial view of Spaceport Cornwall.

The forthcoming mission from Cornwall will contain many firsts: the first orbital launch from the United Kingdom, the first international launch for Virgin Orbit and the first commercial launch from western Europe.

Start Me Up will be the fifth consecutive Virgin Orbit launch to carry payloads for private companies and government agencies. All of the prior 33 satellites were carried by LauncherOne to their precise desired orbit, while demonstrating the ability to fly through and above inclement weather, integrate rapid-call up payloads, and reach a broader range of orbits than would be possible from a traditional ground-launch system.

The launch was acquired by the National Reconnaissance Office (NRO) from Virgin Orbit National Systems, a Virgin Orbit U.S. subsidiary serving classified customers, as the first task order on NRO’s Streamlined Launch Indefinite Delivery, Indefinite Quantity Contract, or “SLIC.”

The missions of the satellites span a wide range of activities aimed at improving life on Earth, including reducing the environmental impact of production; preventing illegal trafficking, smuggling, and terrorism; and a host of national security functions. The full Start Me Up manifest…

IOD-3 AMBER (aka IOD-3)
Developed by Satellite Applications Catapult (“SA Catapult”) and Horizon Technologies and built by AAC Clyde Space, all based in the U.K. IOD-3 Amber is expected to be the first of more than 20 Amber satellites to provide space-based Maritime Domain Awareness (MDA) data to users.

Prometheus-2
Two cubesats owned by the U.K. Ministry of Defense’s (MOD) Defense Science & Technology Laboratory Dstl. These satellites, co-funded with Airbus Defence and Space who are designing them jointly with In-Space Missions, will support MOD science and technology (S&T) activities both on-orbit and on the ground through the development of ground systems focused at Dstl’s site near Portsmouth.

CIRCE (Coordinated Ionospheric Reconstruction CubeSat Experiment)
CIRCE is part of a joint mission between the U.K.’s Defense Science and Technology Laboratory and the U.S. Naval Research Laboratory (NRL).

DOVER
Developed by RHEA Group in the UK, it is the company’s first satellite in its 30-year history. The satellite is being co-funded through the European Space Agency’s (ESA) Navigation Program (NAVISP) and built by Open Cosmos of the United Kingdom. DOVER is a smallsat that was created as a pathfinder for resilient global navigation satellite systems.

ForgeStar-0
Developed by Space Forge of Wales, the satellite is a fully returnable and reusable platform to enable in-space manufacturing. This launch will be the first for the company’s ForgeStar platform and will test future returns from space technology.

AMAN
Oman’s first orbital mission, it is a single EO satellite meant to demonstrate the future feasibility of a larger constellation and was developed after a memorandum of understanding among the Sultanate of Oman, Polish Small Satellite manufacturer and operator SatRev, Poland-originated AI data analytics specialists

TUATARA, and Omani-based merging technology innovator ETCO.
The agreement includes additional planned small satellites, including this, the first in Oman’s history.

STORK-6
Stork-6 is the next installment of Polish Small Satellite manufacturer and operator SatRev’s STORK constellation. Virgin Orbit previously launched two spacecraft in this constellation on a previous launch and looks forward to continuing to launch SatRev’s STORK spacecraft in the future.

Virgin Orbit’s LauncherOne rockets are designed and manufactured in Long Beach, California, and are air-launched from the wing of a converted Boeing 747-400 aircraft named Cosmic Girl. Virgin Orbit’s unique air-launch platform can take off from any runway long enough to handle a Boeing 747. Not reliant on traditional spaceports that support vertical launches, this capability creates a new level of mobility for satellite launch, thereby enabling sovereign launch capability in new markets.

Ian Annett, Deputy CEO at the UK Space Agency, said, “We are entering a new era for space in the UK with the first ever satellite launch from UK soil and from Europe. This is a significant landmark for the nation, the UK Space Agency and for all those who have worked so hard over many years to make our ambitions to create a commercial space launch capability a reality. The development of new orbital launch capabilities is already generating growth, catalysing investment and creating jobs in Cornwall and other communities across the United Kingdom. This will lead to new careers, improved productivity and inspire the next generation of space professionals, and this is just the beginning. I look forward to seeing more launches from other UK spaceports over the next year, putting us firmly on the map as Europe’s leading destination for commercial small satellite launch.”

Dan Hart, Virgin Orbit CEO, said, “After ensuring that every technical aspect is sound and every regulation and code has been satisfied, it is gratifying to see this historic endeavor on the verge of coming to fruition. This launch represents the opening of a new era in the British space industry and new partnerships across industry, government, and allies. Space is already responsible for tens of thousands of jobs across the UK, the global industry is growing quickly, and so is the potential. And this launch is demonstrating that with the Virgin Orbit LauncherOne system an airport can become a spaceport that sends humankind’s innovations on their journey.”

Melissa Thorpe, Head of Spaceport Cornwall, said, “This is a phenomenal moment with incredible international collaboration. Virgin Orbit, the UK Space Agency and all of our partners are breaking new ground to transform access to space across the world from right here in Cornwall. My team at Spaceport Cornwall have worked so hard to get this far and we wish everyone the best of luck as the launch window opens, we are ready.”

Tim Johnson, Director for Space Regulation at the UK Civil Aviation Authority, said, “Effective licensing forms an integral part of UK space activity, and with public safety at the heart of our decision making, we’ve worked with Virgin Orbit and Spaceport Cornwall to assess their applications and issue licences within our expected timeframe, putting the UK framework on a competitive footing with international space regulators. With all licences in place, Virgin Orbit and Spaceport Cornwall are now in a position to deliver a historic first orbital launch from UK shores. We’re proud to be playing our part in facilitating the UK’s space ambitions and enable this country to become a leading launch nation.”

Ionospheric bubbles + blobs being investigated by two NASA smallsats

January 3, 2023 by editorial

Two CubeSats (smallsats) are on a quest to provide insight on space weather disturbances and the subsequent impact on communication signals — this dynamic duo, the Plasma Enhancements in the Ionosphere-Thermosphere Satellite (petitSat) and Scintillation Prediction Observations Research Task (SPORT), arrived at the International Space Station (ISS) on November 27, 2022, as part of SpaceX’s 26th commercial resupply mission for NASA.

The Goddard-led petitSat team is basing its mission on a 6U CubeSat — Dellingr. Goddard engineers developed this smallsat to show that CubeSats could be both reliable and cost effective also while gathering compelling scientific data. The black-colored device at the top of the Dellingr 3-D model depicts the Ion-Neutral Mass Spectrometer that also is flying on petitSat. Credit: NASA/W. Hrybyk

Both of these smallsats deployed from ISS on December 29, 2022, at 8:55 a.m., EST.

Scientists on both missions are most interested in studying a layer in Earth’s upper atmosphere known as the ionosphere, which is where the impacts of space weather on our technology are felt most strongly. The ionosphere is home to many satellites, including the ISS. Radio waves and GPS signals travel through the ionosphere, and variations there can interfere with, or even disrupt, communication signals. Space weather can also create electric currents that can induce electrical charge in orbiting satellites, and, in extreme cases, cause power outages on the ground.

Day in and day out, the ionosphere is cooked by the Sun’s radiation into a soup of positively charged ions and negatively charged electrons, called plasma. Fluctuations in the ionosphere cause low-density and high-density regions — bubbles and blobs — to form in the plasma. These bubbles and blobs can scatter radio signals, sometimes sending them crashing into each other in a phenomenon called scintillation. The result is noisy radio signals, which can reduce the reliability of communication and navigation systems, or even disrupt signals completely.

“If you put a pencil into a glass of water that’s half full, the pencil appears broken,” said Linda Habash Krause, the project scientist for SPORT at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “What happens when you have bubbles? Similar to the pencil in the water, the signals go through ample bends.”

Unfortunately, scientists do not understand exactly how the plasma bubbles and blobs arise. Once petitSat and SPORT are launched from the space station, the two CubeSats will use complementary scientific instruments to investigate the conditions that cause these disruptive features to form.

“The idea is that the science teams will work together and cross compare,” said Jeff Klenzing, the principal investigator of petitSat at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

SPORT is equipped with six instruments to make measurements throughout the ionosphere and these instruments will help determine the conditions that exist just before plasma bubbles form and, ultimately, how their evolution impacts ground-based communications signals. SPORT will transmit data back to the Brazilian National Institute for Space Research (INPE), where the data will be distributed to researchers at INPE, NASA, and other U.S. partners.

In a complementary fashion, petitSat will work to determine what triggers plasma blobs, when they appear, or even how large a region they occupy.

Both petitSat and SPORT will provide improved observations and insights into space weather phenomena which impact communications. These missions will collectively enhance understanding of the ever-changing space environment and amplify current capabilities of smallsats to directly benefit our society.

The more we can earn about space weather — and how to predict it — the better we can protect our astronauts, spacecraft, and technology.
