Transporter-9 | Falcon 9 Block 5 (2024)

D-Orbit

This aerospace company has its headquarters in Italy, where it started to develop a vehicle capable of deorbiting spacecraft which were no longer in use. Later on, it moved to the business of satellite carriers, i.e., space tugs. So far, the firm has launched their vehicles on all of the previous Transporter missions, as well as on Starlink Group 2-5.

ION

D-Orbit’s OTV can carry up to 160 kg of satellites, being capable of accommodating spacecraft of different shapes and sizes. This means MicroSats and CubeSats can be transported from the launcher’s drop-off point to other altitudes or inclinations. After this trip, proprietary (DPOD, DCUBE), or third party dispensers deploy the passengers. ION is also capable of supporting hosted payloads, run from the ground as a part of the carrier itself. On this mission, the ION serial number “SCV013” is going to space.

OSW Cazorla

Named as a homage to Santiago Cazorla, the Spanish footballer, this is Odyssey SpaceWorks’ (OSW) first satellite. Its CEO, Shishir Bankapur, is a huge fan of the sport, particularly of Arsenal FC. Having witnessed this player create wonders on the field — earning him the nick name The Little Magician — and satellite’s small size combined to inspire him. Considering that, together with the magically short design-to-deployment cycle of about one year, he found it fitting to christen the CubeSat after the football star, as he explained in an interview with Everyday Astronaut.

In another remark, Odyssey’s CEO emphasizes that the company’s pursuit of automating in-space research. A considerable amount of such work does not actually require human supervision. In contrast, a bulky backlog is what any scientist has to go through to send their experiments to the International Space Station (ISS).

Certification times for the ISS range between two to three years, versus approximately six months via Odyssey. Finally, this automation not only eliminates hazards to humans, as well as their introduction of errors, but also reduces costs. In fact, in 2021, the reported cost of renting one hour of an astronaut’s work ascended to USD 130,000.

About This Mission

OSW is a New York-based nanosatellite manufacturer, and manifested the OSW Cazorla on this Transporter mission. In order to ready the CubeSat, it made use of one of Endurosat’s buses, assembling into it both subsystems, and payloads. The latter involve the Kaplan Lab at Tufts University and Physical Synthesis, from NY, along with Austrian USound.

In addition to them, German Exolaunch ensures the spacecraft’s integration and deployment through its EXOpod Nova. Final integration to Falcon 9’s second stage occurs via Italian D-Orbit’s ION SCV013 space tug. Additionally, this tug is the one actually in charge of taking the OSW Cazorla to its target destination in orbit: nominally, 540 km (~335 mi) in altitude and 97.5 degrees in inclination.

Once in its orbital home, the CubeSat will work for about three to six months. After completing its expected lifetime and all of its exciting tasks, the satellite will passively deorbit itself. Its atmospheric reentry will destroy it completely, posing no risk to people on the surface, as a consequence.

Spacecraft Description

Featuring a CubeSat form factor of 3U, the Cazorla’s platform comprises an aluminum frame with external dimensions of 30x10x10 cm (~12x4x4 in), and a launch mass of about 3.6 kg (~8 lb). On its longest faces, the satellite presents four non-deployable solar panels, generating, in sum, 70 W of average electrical power. A commercial off-the-shelf (COTS) lithium-ion (Li-Ion) battery with a charge capacity of 161 Wh stores that energy.

The NanoSat includes no propulsion, consequently meaning its orientation happens thanks to three magnetorquers — devices that feel Earth’s magnetic field and interact with it. So that they guarantee a good orientation, there are four Sun sensors, seven gyroscopes, and an inertial measurement unit (IMU) comprising three accelerometers. In order to keep the payloads at the right temperature, a carefully designed insulation wraps each of them. However, if needed, the satellite could feature other means of control.

Communications occur over microwave, specifically the S-Band, along the range between 2025 MHz and 2290 MHz. In particular, power for downlink will be up to 2.0 W, and for uplink, 15 W. Ground stations listening and talking to the OSW Cazorla include about twenty, scattered around the world. On a different note, there are two cameras on board: one external, for taking macro images of the Earth and aiding with orientation and mission assurance; another one internal, monitoring the payloads.

Making use of the bus’ 1.7 U payload volume, two of them are hosted in it, each being a self-contained lab. Inside the first lab a bioreactor will carry out cell culture growth, while the second one is about interactively mixing sounds in real time using in-space sources.

Bioreactor

Odyssey SpaceWorks offers, as one of its proprietary products, bioreactors for a variety of biological applications. It consists of 12 chambers, where cell cultures could grow in space, while researchers monitor them on demand from Earth. A number of options are available for that, as it allows spectrophotometry, as well as detects many parameters, e.g., temperature, pressure, or others. Additionally, its full capabilities for the handling of fluids mean a certain growth can begin or end at any desired point in time, be it microbes, animal tissue, and so on.

The Kaplan Lab at Tufts University will precisely recreate in space an experiment that takes place on Earth. In doing so, it will be able to compare the effectiveness of growing certain cell cultures in those two different contexts. Particularly, the experiment will involve animal muscle tissue from caterpillars, with samples remaining at 38 °C (~100 °F) ±2.0 °C (~3.6 °F). Apart from demonstrating it is possible to achieve this kind of growth robotically, in orbit, and aboard Odyssey SpaceWorks’ satellites, its CEO expanded by explaining the team seeks other goals. That is, the study could provide insight on how to produce food in-space.

Naturally, this is of great interest for the future of crewed, deep-space exploration, changing logistics operations, and reducing costs. Further still, other niches could profit, too, such as pharmaceutical production, protein production, and the effects of prolonged spaceflight. In the latter studies, muscle degradation and other phenomena are the focus. All of them could help understand muscle diseases already occurring on the surface of the planet.

In a further remark, Shishir Bunkapar highlighted that anything in the body, and needing a compressive force to work, will probably struggle in space. Therefore, it could potentially become a subject matter for the company’s reactors.

Blue Marble

In a project that brings together the two US-based Physical Synthesis, and Odyssey SpaceWorks, and also Austrian USound, the second laboratory consists of a synthesizer that can only work in space. Resonating with those having a passion for both music and space, at the crossroads of art and science, this instrument will enable a new way to create sound and music. As a crowdfunding enterprise, different levels of contributors will have different levels of access to the synthesizer, accordingly.

The Blue Marble name references Earth’s photo taken by the Apollo 17 crew while coasting to the Moon. This synthesizer comprises a pressurized capsule where a marble, a glass sphere, floats impelled by a fan on a wall — hence, it would not work on Earth. Laser sensors measure how far from them the sphere is, locating it precisely, while a microphone records any sound. RGB LED lightning and a wide-angle cam complete the internal capturing of the experience.

USound provides a MEMS (Microelectromechanical System) speaker with the characteristic of being non-magnetic, which is particularly useful to avoid interfering with the satellite. A computer controls everything related to this capsule. Externally, flight sensors measuring temperature, flight path, magnetic fields, light intensity, and a camera also partake in the creativity process. That is, all of this data is relayed back to Earth, where users can compose music. Depending on the case, they can play audio files, change the lighting, or pulse the fan, increasing the feedback level.

Profiting from the in-space interactions inside the Blue Marble, selected artists will compose, such as Andrew Huang, Benn Jordan, Trovarsi, and Maysun. People from the analog astronaut community will be a part of this musical adventure, including our very own MaryLiz Chylinski. Among other rewards, the project includes a vinyl album with the resulting tracks, which aims at fostering musical creativity.

Exolaunch

The Germany-based company offers a series of services, from payload integration, to deployment, and mission management. In order to provide them, Exolaunch developed products such as separation hardware, CubeSat deployers, payload port adapters, deployment sequencers, and it is projecting an OTV named Reliant. Notably, the firm has all previous Transporter missions under its extensive flight expertise.

Deployment Systems

In order to better fit customers’ needs, Exolaunch may assign one or many of its deployment systems. These include:

• CarboNIX: this is a shock-free separator system capable of handling MicroSats massing in the range of 10 kg to 250 kg. To ensure this, different standard sizes are offered, as well as customization. Six CarboNIX separation systems were used in Transporter-9.
• EXOpod: flying since 2017, these deployers have evolved to host all sorts of CubeSat sizes, from 0.25U all the way up to 16U, allowing, in addition, for some combination. 15 EXOpods Nova were used during this mission.
• EXOport: these multiport adapters enable the use of one port on a rideshare plate for a whole CubeSat cluster. A combination of the previous two systems can be used for satellite deployment. Probably no EXOport is used this time, and SpaceX’s Rideshare Plates are used instead.

Payloads Integrated by Exolaunch

The company is flying for the 12th time with SpaceX, making this one its 24th overall mission. In particular, this time, Exolaunch is integrating 34 small satellites for many customers from all over the world.

NinjaSat

True to the spirit of Transporter missions, NinjaSat shows how even the “small guy” can dream and try to make reality a very exciting project. Given, RIKEN, the Institute of Physical and Chemical Research is a prestigious Japanese research entity. However, as the researchers state, excellent scientific observation is completely possible, in spite of using a small satellite. NinjaSat represents precisely that, comprising relatively inexpensive parts and following a development cycle of about two years.

Generalities, Commissioning, Operation

This spacecraft will look at binary systems including a normal star and a black hole, or a neutron star. These are, as a matter of fact, bright sources of X-Rays. Additionally, the CubeSat will pursue this endeavor for a prolonged period of time. Previously, the plan was for the CubeSat to see deployment from the International Space Station (ISS). This, however, could have meant its lifetime on orbit would have been reduced to even less than a year. The higher SSO where Falcon 9 is dropping it allows for a two year-long mission, though it exposes the satellite to auroral regions. On the other hand, it enables more passes over a ground station near the poles, which is beneficial for opportunity observations.

Once it is floating in space, NanoAvionics will check the good health of the satellite bus for about a month. Moving into the operational phase, another week will see the start-up of the radiation belt monitor (RBM), mapping where the satellite can operate or not. Thirdly, the gas multiplier counter (GMC) needs to go through its own commissioning for a week, too. Calibration occurs by pointing at the Crab Nebula, a well-known X-Ray source. During this phase, a series of tests and check-ups will take place, ensuring pointing accuracy, GMC mutual alignment, and star tracker alignment with respect to both GMCs.

Calibrations should be complete by December 2023, or January 2024, making way for astronomical observations to begin. Throughout its operational life, NinjaSat will be in one from its three different modes. The first one is the “charging mode,” which does not allow observations. When it completes the charge, the satellite switches to the “pointing mode,” observing a predefined celestial object for as long as possible. This mode should comprise as much as 30 % to 50 % of its functioning time. Finally, a “ground communications mode,” to exchange all needed information and commands.

The Spacecraft

For its platform, NinjaSat uses NanoAvionics’ M6P bus, as it is flight-proven and enables little need for customization. Mitsui Bussan Aerospace secured the contract for the Lithuanian company not only to build the NinjaSat on its proprietary bus, but also to integrate the RIKEN-developed payloads. These comprise two gas multiplier counters (GMCs), as well as two radiation belt monitors (RBMs).

An onboard flight computer commands the attitude control system (ACS), which consists of:

• six sun sensors,
• one star tracker,
• four reaction wheels,
• one 3-axis magnetorquer,
• one inertial sensor,
• 3-axis magnetometers, and
• one GNSS (GPS) receiver.

Thanks to this system, the satellite is capable of achieving a pointing accuracy of 0.06° the vast majority of the times (95 % confidence). On a different note, its electrical system consists of the solar arrays — partly deployable, partly fixed — that work coupled with Li-ion batteries. Like this, the system satisfies the NanoSat’s demand of 16.4 W daily. In sum, all the whole of the satellite masses at 8.14 kg (~18 lb).

The Instruments

Each payload pair — one GMC, one RBM — takes up a volume of 2U, and hence the selection of a 6U bus. Inside of it, the X-Ray detectors, the GMCs, occupy as much of the room destined to instruments inside the satellite. In turn, this increases the chances of a better quality observation. The positioning of the deployable solar arrays is equally important, preventing noise in the measurements from Sun-originated X-Rays.

Gas Multiplier Counter (GMC)

For the purpose of detecting X-Rays from celestial bodies, there are actually two of these instruments aboard NinjaSat. Each of them showcases a volume of 1U, a mass of 1.2 kg (~2.5 lb), and an electrical consumption of 1.8 W. Its field of view is of 2.3°, and its area of observation is of 32 cm² (~5 in²). Each GMC comprises an aluminum chamber with its insides filled with a mix of gases: xenon (75 %), argon (24 %), and dimethyl ether (1 %, all in volume).

The observation surface is a window allowing for X-Rays to go into the chamber of the GMC. Free electrons emission occurs, because of the photoelectric effect. This happens when electrons get loose as a consequence to atoms being hit by high energy radiation, like X-Rays. In this case, the gases inside the chamber lose some of their electrons.

In turn, high electrical potential (colloquially, voltage) makes the electrons drift toward an electrode. Before hitting the latter, a gas electron multiplier produces 400 times more electrons than it receives. Therefore, a readable signal comes out of the chamber, subsequently passing through more amplifiers, and filters. Finally, a clean measurement of the X-Ray comes out of the GMC.

As an important note about the GMCs are their vital interaction with the RBMs. Even when throughout an orbit each GMC stops any observation as it flies through fixed, high radiation regions, the RBMs can also shut it down. The South Atlantic Anomaly (SAA) or auroral zones are at fixed points on the satellite’s path, but another event, like a Solar flare, could damage the instrument.

Radiation Belt Monitor (RBM)

These are smaller instruments, each occupying only 0.07U of the payload volume, with a mass of 0.07 kg (~0.15 lb), and consuming 1 W of energy. The main task of the RBM is to detect high energy particles, such as electrons with an energy higher than 150 keV, and protons higher than 300 keV. Comparatively, its detection surface is much smaller measuring only 1.0 cm² (~0.2 in²). Additionally, it has a thickness of 500 µm, and once operational, it will constantly work warning the GMCs of any dangerous increase in particles.

Science

X-rays astrophysics requires a satellite with an instrument in orbit, since such radiation is absorbed by the atmosphere. As a result, X-ray astrophysics is a relatively new discipline. Previous CubeSats for high energy astrophysics (HEA) featured small sensors, and lacked pointing capability. To date, no general-purpose Cubesat dedicated to X-ray astronomy until the launch of NinjaSat.

The CubeSat is capable of detecting X-ray sources brighter than a few 10^-19 erg/(cm² s) with a time-tagging resolution of 61 µs. That is, this allows it see the fast variations of rays originating from accretion processes between stars and black holes, or stars and neutron stars. In addition, NinjaSat can identify transient X-Ray objects by surveying the entire sky, like MAXI on the ISS.

Furthermore, accretion and relativistic jets from these binary systems will be among the study subjects. In order to do so, collaborative efforts with ground-based and space-based optical and radio instruments will take place. Moreover, the measurement of neutron star rotation can help other researchers in detecting gravitational waves, similar to what the LIGO observatory does.

Space Selfie Stick

Germany-based DCubed is flying one of its most well-known products: the selfie stick. Installed on Exotrail’s SpaceVan, it will deploy and then look back at the space tug. Thomas Sinn, the company’s CEO, described in an interview with Everyday Astronaut how the concept of this item was born out of a playful idea. Nowadays, the Space Selfie Stick is very popular, and it serves both mission assurance, and marketing purposes.

Dcubed became an entity when Sinn was working for a side project that would end up being part of Rocket Lab’s “It’s Business Time” mission. During the design phase, the now CEO of the firm could not find an appropriate release device. That was the kick-off point, as by using not much more than a basic 3D printer, his team developed a component that performed perfectly fine, setting the future course.

Other Projects

Presently, the company has many exciting projects on the works, and some of them are coming up really soon. An example of that is the In-Space Manufacturing (ISM) demo, that will actually fly in two occasions: on Skyroot’s maiden flight, expected in February, 2024, and on SpaceX’s Transporter-11 via a D-Orbit OTV, expected in June, 2024. These ISM demos are proofs of concept, extruding a UV-sensitive polymer in a very similar fashion to how 3D printers work. In contrast, there will be no bed on which a structural element, the part chosen for the test, could “grow.”

The underlying idea is that if this experiment gives good results, it would make the manufacturing of whole structures on orbit closer to reality. Given that the launch onboard a rocket represents the highest stresses a payload goes through, its structures’ design focuses on that phase. However, once in space, they do not need to endure such great efforts. It follows that by building it where it will live, costs should considerably go down. In fact, Sinn is of the opinion that the difference could be of one or two orders of magnitude.

Another very exciting prospect is the deployment of a foldable solar array, that should ride atop the RFA One on its maiden flight. In line with origami techniques, the array is stored inside the volume of a 1U CubeSat. Once all the other payloads separate from the rocket’s upper stage, the solar array will unfold without separating. Also in the solar array business, DCubed aims at supplying space tugs with more powerful solar arrays. This is a much needed feature considering this kind of vehicle could see lots of action in the coming years.

Beyond this, the company has set its sight on a large number of ideas and concepts. From components, passing through solar arrays and deployable structures, and getting even into the lunar bases realm, the future certainly looks exciting for DCubed!
