Hurtigruten Expeditions and Speedcast complete fleetwide implementation of Starlink as part of managed service solution

October 13, 2022 by editorial

Speedcast, a communications and IT services provider, has partnered with Hurtigruten Expeditions to complete fleetwide implementation of SpaceX’s Starlink Low Earth Orbit (LEO) broadband connectivity. Hurtigruten Expeditions, a major expedition cruise line, and its long-time connectivity partner, Speedcast, began initial testing and integration of Starlink’s LEO service onboard the fleet in March. Roll-out of the high-speed, low-latency connectivity will be finished by end of October, making the cruise line one of the first in the industry to complete a fleetwide installation.

Starlink’s broadband connectivity is being integrated via Speedcast’s advanced network management technologies, blending the LEO coverage with multiple transmission paths delivered to the fleet as part of a complete managed service. This includes traditional geostationary (GEO) orbit coverage, and 4G/5G for Hurtigruten Expeditions’ high-demand applications.

“With vessels operating in some of the most remote and spectacular areas of the world, Hurtigruten Expeditions is an ideal partner for introducing groundbreaking technology in the cruise industry,” said Joe Spytek, Chief Executive Officer at Speedcast. “Speedcast’s expertise lies in our ability to combine all available connectivity paths and manage a complete service that offers the highest levels of uptime, availability, and performance. Hurtigruten’s vessels sailing from more traditional GEO coverage areas into lower look-angle locations, such as Antarctica, Alaska, Greenland, and the Chilean fjords, will be bolstered with this new LEO coverage, where available.”

For Hurtigruten Expeditions, Speedcast’s implementation of Starlink brings faster, more reliable internet to its guests and crew.

“As the world leader in exploration travel, it’s only fitting that we bring the world’s most innovative technologies onboard our ships to further enhance the experience and day-to-day lives for our guests, crew, partners and the communities we visit,” said Hurtigruten Expeditions CEO, Asta Lassesen.

Earlier this month, Speedcast announced an agreement with SpaceX’s Starlink to offer the broadband service to enterprise and maritime customers. Speedcast will integrate Starlink connectivity into the multi-path, multi-orbit service that it offers, leveraging its SIGMA network platform and SD-WAN solutions, which make it possible to prioritize traffic, offer guaranteed service levels, and fully manage the customer experience.

Speedcast and Hurtigruten Expeditions’ multi-months trials, integrating the new technology into the managed connectivity service onboard a Hurtigruten Expeditions vessel, showcased how Speedcast’s network design enabled seamless failover from Starlink’s LEO connectivity to Speedcast’s global maritime network.

Three of Hurtigruten Expeditions’ vessels will operate in Antarctica this season, introducing Starlink to Antarctic waters. The new LEO service is slated to add Antarctic maritime coverage in Q4 2022.

“Our partnership with Speedcast and fleetwide introduction of the new service not only puts us ahead of the rest of the cruise industry, it also puts us ahead of the technology. When Starlink introduces maritime coverage in Antarctica and the Arctic, we will be ready,” said Lassesen.

Hurtigruten Expeditions offers free internet connectivity not only for guests, but also for all crew members.

“The introduction of new technology makes it easier for everyone onboard to remain connected with friends, family and loved ones, no matter where they are. We’re leading by example and challenge all cruise lines to make internet free for crew members,” said Lassesen.

Developed to—among other goals—track illegal maritime activities, Horizon Technologies’ Amber™ UK smallsat launch is upcoming

October 13, 2022 by editorial

Horizon Technologies, a British maritime intelligence company that developed innovative detection technology that equips governments to fight illegal maritime activity, is set to make history as it prepares for a momentous UK launch from Spaceport Cornwall.

Horizon Technologies’ first Amber™ cubesat will be launched from Virgin Orbit’s 747 named Cosmic Girl, sent into space and placed in orbit as part of the ‘Start Me Up‘ Mission in the next few weeks.

Perhaps paying closest attention will be a small team of engineers watching from a workshop in Reading where a wild idea was birthed to fight piracy on the high seas, not by military might, but by the simple process of tracking their phones.

Takeoff of Virgin Orbit’s Cosmic Girl 747.

Amber’s patented, technology is the brainchild of Horizon Technologies CEO, John Beckner, who discovered the demand for satphone detection while visiting South Africa during the Somali pirate crisis where criminals were communicating via satellite telephones.

With clandestine maritime trade more relevant than ever, as Russian tankers seek to illegally trade and traffic fuel to support its war effort in Ukraine, the satellite will be used to capture sanctions-busters red-handed, bolstering the international effort to combat Russian aggression at a pivotal time.

Upon his return to the UK, Beckner formed a team of visionary experts to put together and manufacture a system which could be installed on aircraft to locate Sat Phones at sea. Beckner’s team integrated off-the-shelf, electronic components, and named this system, “FlyingFish.”

While Horizon Technologies started out as Beckner’s consulting company, it quickly grew into a profitable UK tech startup. FlyingFish™ production and support has since moved out of the garage and these systems are flying on numerous government aircraft worldwide. It is a key tool for many governments and agencies as part of their ISR (Intelligence, Surveillance, and Reconnaissance) capabilities.

In 2019, Beckner envisioned expanding FlyingFish™ capability to a global real-time platform, only possible from outer space. Once more, he challenged his team to come up with a solution. The idea was to develop and launch a constellation of small, shoebox sized cubesats to provide users with worldwide 24/7 capability in combating illegal activity at sea.

Buoyed by an initial grant by Innovate UK, the first of these satellites, named Amber-1, was developed in a partnership between Horizon Technologies and the Satellite Applications Catapult (SAC), and forms part of SAC’s In-Orbit Demonstration program (IOD). The satellites themselves are manufactured by AAC Clyde Space in Glasgow, Scotland.

Unlike Horizon Technologies’ hardware products, Amber™ is a data service. Once on-orbit, the tiny Amber™ cubesats will provide governments and companies with unique worldwide data ranging from radar “fingerprints” to satellite phones’ GPS locations to help combat illegal fishing, smuggling, trafficking, piracy, and terrorism. The initial data from Amber™ will be provided to the UK Government’s Joint Maritime Security Centre (JMSC).

Amber™ has a myriad of commercial applications as well. Since the smallsat detects data transmissions, it will have the capability of adding a key capability to the Industrial Internet of Things (IIoT). Just as it provides an important tool to verify ships’ locations, its receivers can also track vehicles, trains and aircraft using satellite data services. With today’s worldwide supply chain issues, the need to track all manner of transportation has never been greater.

“The first Amber™ mission is a milestone,” said Beckner.” “It demonstrates how public/private partnerships with SMEs, allow ideas and innovation to be turned into real products and services. Innovate UK and organizations like the Satellite Applications Catapult, give small companies the chance to rapidly deploy innovative technologies; and in our case, all the way to space!”

The first mission, scheduled for 2024, will see Exotrail’s spacevan™ vehicle demonstrate its ability to change satellite altitude and plan in combined maneuvers — a game changer for small satellite constellation deployment. In a second mission scheduled for 2025, the company will transport a microsatellite from the launcher’s delivery point to its final orbit.

This landmark contract is another meaningful step towards establishing Exotrail as a worldwide space logistics leader and creates significant opportunities for commercial and institutional space transportation companies to leverage the remaining capacity of these missions.

Exotrail’s spacedrop™ service gives satellite operators the flexibility they need to get their satellites to their operational orbits. Exotrail offers an integrated service by procuring access to space, integrating the platform with customers satellites onboard and performing required operations in orbit. The spacedrop™ service will be inaugurated in October 2023 and the missions performed in the context of France 2030 will benefit from an upgraded version of the vehicle; notably an improved propulsion system and a platform offering a greater payload capacity.

This contract emphasizes the benefits of a holistic vision of space mobility. Exotrail’s spacedrop™ vehicle will be powered by Exotrail’s space proven high-thrust, flexible propulsion systems spaceware™ electric thrusters and orbital operations will be completed using its proprietary software solution, spacetower™. Exotrail’s expertise in these two critical components gives its spacedrop™ service a clear edge on its competitors.

Jean-Luc Maria, Exotrail’s CEO stated, “We are honored to have been selected as part of the ambitious France 2030 plan, aimed at building next space leaders. This contract rewards Exotrail’s hardworking teams and the space logistics vision the company has pursued since its very foundation. It’s a crystal-clear message to our customers: spacedrop™ is the go-to service for operators looking for a high-capacity, flexible and competitive transfer solution in low, medium, geostationary orbits, and farther.”

UPDATE 1: NASA’s DART mission can now confirm the asteroid’s motion in space was altered

October 11, 2022 by editorial

This imagery from NASA’s Hubble Space Telescope from Oct. 8, 2022, shows the debris blasted from the surface of Dimorphos 285 hours after the asteroid was intentionally impacted by NASA’s DART spacecraft on Sept. 26. The shape of that tail has changed over time. Scientists are continuing to study this material and how it moves in space, in order to better understand the asteroid.Credits: NASA/ESA/STScI/Hubble

Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft’s kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the motion of a celestial object and the first full-scale demonstration of asteroid deflection technology.

“All of us have a responsibility to protect our home planet. After all, it’s the only one we have,” said NASA Administrator, Bill Nelson. “This mission shows that NASA is trying to be ready for whatever the universe throws at us. NASA has proven we are serious as a defender of the planet. This is a watershed moment for planetary defense and all of humanity, demonstrating commitment from NASA’s exceptional team and partners from around the world.”

Prior to DART’s impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid, Didymos. As DART’s intentional collision with Dimorphos on September 26th, astronomers have been using telescopes on Earth to measure how much that time has changed. Now, the investigation team has confirmed the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.

Before its encounter, NASA had defined a minimum successful orbit period change of Dimorphos as change of 73 seconds or more. This early data show DART surpassed this minimum benchmark by more than 25 times.  

“This result is one important step toward understanding the full effect of DART’s impact with its target asteroid,” said Lori Glaze, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “As new data come in each day, astronomers will be able to better assess whether, and how, a mission like DART could be used in the future to help protect Earth from a collision with an asteroid if we ever discover one headed our way.”

The investigation team is still acquiring data with ground-based observatories around the world – as well as with radar facilities at NASA Jet Propulsion Laboratory’s Goldstone planetary radar in California and the National Science Foundation’s Green Bank Observatory in West Virginia. They are updating the period measurement with frequent observations to improve its precision.

Focus now is shifting toward measuring the efficiency of momentum transfer from DART’s roughly 14,000-mile (22,530-kilometer) per hour collision with its target. This includes further analysis of the “ejecta” – the many tons of asteroidal rock displaced and launched into space by the impact. The recoil from this blast of debris substantially enhanced DART’s push against Dimorphos – a little like a jet of air streaming out of a balloon sends the balloon in the opposite direction.

To successfully understand the effect of the recoil from the ejecta, more information on of the asteroid’s physical properties, such as the characteristics of its surface, and how strong or weak it is, is needed. These issues are still being investigated.

“DART has given us some fascinating data about both asteroid properties and the effectiveness of a kinetic impactor as a planetary defense technology,” said Nancy Chabot, the DART coordination lead from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. “The DART team is continuing to work on this rich dataset to fully understand this first planetary defense test of asteroid deflection.”

For this analysis, astronomers will continue to study imagery of Dimorphos from DART’s terminal approach and from the Light Italian CubeSat for Imaging of Asteroids (LICIACube), provided by the Italian Space Agency, to approximate the asteroid’s mass and shape. Roughly four years from now, the European Space Agency’s Hera project is also planned to conduct detailed surveys of both Dimorphos and Didymos, with a particular focus on the crater left by DART’s collision and a precise measurement of Dimorphos’ mass.

Johns Hopkins APL built and operated the DART spacecraft and manages the DART mission for NASA’s Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office. Telescopic facilities contributing to the observations used by the DART team to determine this result include: Goldstone, Green Bank Observatory, Swope Telescope at the Las Campanas Observatory in Chile, the Danish Telescope at the La Silla Observatory in Chile, and the Las Cumbres Observatory global telescope network facilities in Chile and in South Africa.

NOTE: Neither Dimorphos nor Didymos poses any hazard to Earth before or after DART’s controlled collision with Dimorphos.

Original posting…

After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted its asteroid target on Monday, the agency’s first attempt to move an asteroid in space.

The smallsat companion aboard NASA’s Double Asteroid Redirection Test (DART) — LICIACube from the Italian Space Agency — successfully separates from the main spacecraft, popping out of its spring-loaded box to capture valuable information about DART’s impact into an asteroid to forward information that will assist with future planetary defense efforts. Image is courtesy of Johns Hopkins Applied Physics Laboratory.

Mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, announced the successful impact at 7:14 p.m. EDT.

Asteroid moonlet Dimorphos as seen by the DART spacecraft 11 seconds before impact. DART’s onboard DRACO imager captured this image from a distance of 42 miles (68 kilometers). This image was the last to contain all of Dimorphos in the field of view. Dimorphos is roughly 525 feet (160 meters) in length. Dimorphos’ north is toward the top of the image.

As a part of NASA’s overall planetary defense strategy, DART’s impact with the asteroid Dimorphos demonstrates a viable mitigation technique for protecting the planet from an Earth-bound asteroid or comet, if one were discovered.

“At its core, DART represents an unprecedented success for planetary defense, but it is also a mission of unity with a real benefit for all humanity,” said NASA Administrator, Bill Nelson. “As NASA studies the cosmos and our home planet, we’re also working to protect that home, and this international collaboration turned science fiction into science fact, demonstrating one way to protect Earth.”

DART targeted the asteroid moonlet Dimorphos, a small body just 530 feet (160 meters) in diameter. It orbits a larger, 2,560-foot (780-meter) called Didymos — neither asteroid poses a threat to Earth.

The mission’s one-way trip confirmed NASA can successfully navigate a spacecraft to intentionally collide with an asteroid to deflect it, a technique known as kinetic impact.

The investigation team will now observe Dimorphos using ground-based telescopes to confirm that DART’s impact altered the asteroid’s orbit around Didymos. Researchers expect the impact to shorten Dimorphos’ orbit by about 1%, or roughly 10 minutes; precisely measuring how much the asteroid was deflected is one of the primary purposes of the full-scale test.

“Planetary Defense is a globally unifying effort that affects everyone living on Earth,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “Now we know we can aim a spacecraft with the precision needed to impact even a small body in space. Just a small change in its speed is all we need to make a significant difference in the path an asteroid travels.”

The spacecraft’s sole instrument, the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), together with a sophisticated guidance, navigation and control system that works in tandem with Small-body Maneuvering Autonomous Real Time Navigation (SMART Nav) algorithms, enabled DART to identify and distinguish between the two asteroids, targeting the smaller body.

These systems guided the 1,260-pound (570-kilogram) box-shaped spacecraft through the final 56,000 miles (90,000 kilometers) of space into Dimorphos, intentionally crashing into it at roughly 14,000 miles (22,530 kilometers) per hour to slightly slow the asteroid’s orbital speed. DRACO’s final images, obtained by the spacecraft seconds before impact, revealed the surface of Dimorphos in close-up detail.

Fifteen days before impact, DART’s cubesat companion, the Light Italian CubeSat for Imaging of Asteroids (LICIACube), provided by the Italian Space Agency, deployed from the spacecraft to capture images of DART’s impact and of the asteroid’s resulting cloud of ejected matter. In tandem with the images returned by DRACO, LICIACube’s images are intended to provide a view of the collision’s effects to help researchers better characterize the effectiveness of kinetic impact in deflecting an asteroid. As LICIACube does not carry a large antenna, images will be downlinked to Earth one by one in the coming weeks.

“DART’s success provides a significant addition to the essential toolbox we must have to protect Earth from a devastating impact by an asteroid,” said Lindley Johnson, NASA’s Planetary Defense Officer. “This demonstrates we are no longer powerless to prevent this type of natural disaster. Coupled with enhanced capabilities to accelerate finding the remaining hazardous asteroid population by our next Planetary Defense mission, the Near-Earth Object (NEO) Surveyor, a DART successor could provide what we need to save the day.”

With the asteroid pair within 7 million miles (11 million kilometers) of Earth, a global team is using dozens of telescopes stationed around the world and in space to observe the asteroid system. Over the coming weeks, they will characterize the ejecta produced and precisely measure Dimorphos’ orbital change to determine how effectively DART deflected the asteroid. The results will help validate and improve scientific computer models critical to predicting the effectiveness of this technique as a reliable method for asteroid deflection.

“This first-of-its-kind mission required incredible preparation and precision, and the team exceeded expectations on all counts,” said APL Director, Ralph Semmel. “Beyond the truly exciting success of the technology demonstration, capabilities based on DART could one day be used to change the course of an asteroid to protect our planet and preserve life on Earth as we know it.”

Roughly four years from now, the European Space Agency’s Hera project will conduct detailed surveys of both Dimorphos and Didymos, with a particular focus on the crater left by DART’s collision and a precise measurement of Dimorphos’ mass.

Johns Hopkins APL manages the DART mission for NASA’s Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office.

Mangata Networks selects Honeywell to provide control systems for new satellite constellations

October 11, 2022 by editorial

Mangata Networks has selected Honeywell‘s space integrated attitude control system (IACS) in support of its new constellations comprising 32 satellites. Mangata’s new, highly elliptical orbit (HEO) and MEO satellite constellations provide communications and weather monitoring in areas that typically lack in quality internet connectivity.

The precision and reliability of Honeywell’s space IACS platform enable seamless and continuous connectivity for users of Mangata’s network of telecommunications satellites. Together with other core elements of Mangata’s network architecture, the goal is to make possible secure and high-speed connectivity for businesses and individuals in remote areas without adequate access to the internet.

IACS is a comprehensive control and steering solution for satellites that ensures the proper altitude and position of space vehicles, which is essential for effective signal communication and solar power generation to keep the satellites operating efficiently.

“We are excited to announce our partnership with Honeywell as it will design, develop and deliver the avionics for Mangata’s constellation satellites,” said Andreas Doulaveris, vice president, space systems at Mangata Networks. “Honeywell is first-in-class, and we are looking forward to continuing our relationship as together we bring Mangata Networks’ vision to fruition.”

“The traditional geostationary equatorial orbit (GEO) constellations already provide broadband and other connectivity solutions for consumers and commercial applications, but the existing technology has become too slow by today’s standards,” said Ricky Freeman, president, defense, and space at Honeywell Aerospace. “As a result, global telecommunications companies are modernizing their networks and have started to look to HEO and MEO to provide higher data rates while lowering latency. Honeywell has extensive experience and a strong pedigree in navigation, data handling and momentum control products. Each of these is well suited to support these HEO and MEO satellite constellations, and our IACS platform will provide Mangata Networks with the precision and reliability it needs to operate its network of telecommunications satellites.”

DARPA’s SPCE program to push beyond power limitations in space

October 11, 2022 by editorial

Rapidly proliferating smallsats in LEO are expanding space-based capabilities critical to both government and industry. As the subsequent, ever-increasing demand strains operational limitations of LEO satellites, DARPA’s new Space Power Conversion Electronics (SPCE) program seeks greater efficiencies in usable power in the harsh space environment.

Space-based power consumption generates heat that can only be offloaded through radiation. This type of thermal management constrains the maximum operating power a satellite can consume. Usable power is further reduced by the inefficiencies in point-of-load (POL) converters.

The main function of POL converters is to deliver power at significantly lower voltage than the high-voltage main satellite power bus for payloads. These lower-voltage applications include onboard microsystems that execute computing and other electronic functions.

Today’s space POL converters comprise radiation-hardened, high-voltage switching transistors and radiation-resistant passive and active circuit elements to survive in challenging space conditions. These components, subject to extensive development and testing processes to withstand radiation damage, trail the performance of their counterparts built for non-radiated applications, such as ground-based systems. The latter can leverage faster, more cutting-edge components, but the radiation-hardening process reduces POL power efficiency in space to as little as 60% – severely limiting a satellite’s capabilities and battery lifetime.

Improved power efficiency in the harsh, radiated space environment is necessary to meet demands for new, increasingly advanced mission capabilities as well as extended lifetimes for persistent LEO constellations.

The goal of DARPA’s SPCE program is to boost the performance of space-based POL systems through development of high-voltage, radiation-tolerant transistors and integrated circuit technologies that are low-loss, high-voltage, and radiation tolerant.

The SPCE program consists of three program phases. The 20-month first phase will target radiation-tolerant, high-performance, high-voltage transistors development, while Phase 2 focuses on low-loss integration development and Phase 3 targets high-efficiency conversion circuit demonstration.

“SPCE will exploit a combination of materials and device-engineering, integrating advanced materials of different types and composition – or heterogenous material synthesis – and novel device designs. This will help achieve radiation-tolerant power transistors for space that offer performance that is competitive with terrestrial, state-of-the-art wide bandgap semiconductor power transistors,” said Jason Woo, DARPA program manager for SPCE. “With proliferation in LEO, 60% efficiency is no longer good enough.”

According to Woo, if successful, SPCE breakthroughs could extend system lifetimes and create new mission capabilities for persistent LEO constellations operating in difficult space terrains.
