Boeing and CASIS Award $500,000 for Microgravity Research through MassChallenge

BOSTON, Nov. 6, 2017 – Boeing [NYSE: BA] and the Center for the Advancement of Science in Space (CASIS) have again joined forces to promote the use of the International Space Station (ISS) as an orbiting laboratory capable of producing cutting-edge research across numerous scientific disciplines. The two organizations on Nov. 2 granted a total of $500,000 to three microgravity research companies through startup accelerator MassChallenge™.

The awards to Cellino Biotech, Guardion Technologies, and MakerHealth mark Boeing and CASIS’s fourth year of collaboration on the “Technology in Space” prize at MassChallenge Boston.

CASIS is the nonprofit organization responsible for managing and promoting research onboard the ISS U.S. National Laboratory. Boeing is the ISS prime contractor, responsible for designing, building and processing the American modules and the integrated truss system that powers the station, for sustaining engineering, and for processing experiment and systems racks for launch, installation and operation.

The grants will provide seed funding for the three awarded companies and assist with hardware costs for flight to the ISS National Lab. With this latest collaboration, Boeing and CASIS have jointly partnered to fund 11 separate innovative startups through MassChallenge. The second round of these awarded investigations, Biorasis and Launchpad Medical, is scheduled to launch to the ISS National Laboratory in early December.

This year’s winning projects had to incorporate science or technology initiatives that would effectively use and benefit from ISS National Lab capabilities. CASIS will continue to work with additional MassChallenge “Technology in Space” proposers to build on their ideas and potentially transform them into flight-ready projects.

Below are the 2017 recipients of the “Technology in Space” award:

Cellino Biotech Inc.

Investigating Proliferation of NanoLaze Gene-edited induced Pluripotent Stem Cells aboard the ISS

The goal of this proposal is to gene-edit induced Pluripotent Stem Cells (iPSCs) using Cellino Biotech’s platform, NanoLaze™, on Earth and then investigate their proliferation under microgravity on ISS to show enhanced stemness of the cells. This data would unlock the potential to generate the 200 to 500 million stem cells necessary for a cell-based therapy, which is not possible with currently available stem cell technologies on Earth. Cellino will use its proprietary NanoLaze™ platform to deliver a powerful gene-editor, CRISPR/Cas9, to iPSCs. Maximizing stemness in microgravity would enable Cellino and therapeutic partnering companies to supply more patients with universal cells to treat critical genetic diseases such as Alzheimer’s, Parkinson’s, and hemophilia, which are among the estimated 6,000 genetic diseases in existence, of which 95 percent have no approved therapies.

Guardion Technologies

Convection-Free Synthesis of 2D Nanomaterials on the ISS for Improved Radiation Detection

Guardion Technologies is developing miniaturized ionizing radiation detectors, which can be deployed in large numbers to provide real-time monitoring networks for interrogating possible radioactive sources. Such networks will enable early and/or remote detection of possible radiological threats, and serve as a highly effective triage mechanism for emergency responders. At the core of the miniaturizable detection technology is a novel patent-pending process that utilizes quantum properties of certain nanomaterials such as carbon nanotubes, graphene, and other atomically thin materials such as monolayers (2D). Guardion hypothesizes that convection-free synthesis of 2D materials in microgravity will result in samples with greater crystallinity, higher electronic mobility, and lower electronic noise, which will enable an enhanced signal-to-noise ratio of these detectors.


AmpliRx: A Manufacturing Pharmaceutical Lightweight Instrument

MakerHealth has created the AmpliRxTM modular biochemical manufacturing platform that enables distributed, affordable, and scalable production of medications. The MIT-developed innovation includes a first-in-class membrane-to-membrane continuous flow reactor system that can operate without pumps or advanced instrumentation and runs using minimal power by using proprietary modular Ampli blocks that connect to each other to form reaction-to-reaction pathways. Gravity and, subsequently, evaporation play an adverse role to fluid flow and reaction reliability of membrane-based chromatographic flow. While previous work has been done to understand the effects of microgravity on the separation of substances, the AmpliRx platform focuses on fusion-based reactions of substances during organic synthesis and bioprocessing reactions. Experiments in a microgravity environment will inform our understanding of and help to optimize membrane material properties and geometries. Mitigating these adverse forces will be beneficial to increasing the spread rates and reliability, thus decreasing reaction times within our platform.

Final award of any grant money is contingent upon acceptance of legal terms and conditions between recipient, CASIS, and Boeing.

Heating ocean moon Enceladus for billions of years

Enceladus interior

Heating ocean moon Enceladus for billions of years

6 November 2017

Enough heat to power hydrothermal activity inside Saturn’s ocean moon Enceladus for billions of years could be generated through tidal friction if the moon has a highly porous core, a new study finds, working in favour of the moon as a potentially habitable world. 

A paper published in Nature Astronomy today presents the first concept that explains the key characteristics of 500 km-diameter Enceladus as observed by the international Cassini spacecraft over the course of its mission, which concluded in September.

This includes a global salty ocean below an ice shell with an average thickness of 20–25 km, thinning to just 1–5 km over the south polar region. There, jets of water vapour and icy grains are launched through fissures in the ice. The composition of the ejected material measured by Cassini included salts and silica dust, suggesting they form through hot water – at least 90ºC – interacting with rock in the porous core.
These observations require a huge source of heat, about 100 times more than is expected to be generated by the natural decay of radioactive elements in rocks in its core, as well as a means of focusing activity at the south pole.

The tidal effect from Saturn is thought to be at the origin of the eruptions deforming the icy shell by push-pull motions as the moon follows an elliptical path around the giant planet. But the energy produced by tidal friction in the ice, by itself, would be too weak to counterbalance the heat loss seen from the ocean – the globe would freeze within 30 million years.

Enceladus plumes

As Cassini has shown, the moon is clearly still extremely active, suggesting something else is happening.

“Where Enceladus gets the sustained power to remain active has always been a bit of mystery, but we’ve now considered in greater detail how the structure and composition of the moon’s rocky core could play a key role in generating the necessary energy,” says lead author Gaël Choblet from the University of Nantes in France.

In the new simulations the core is made of unconsolidated, easily deformable, porous rock that water can easily permeate. As such, cool liquid water from the ocean can seep into the core and gradually heat up through tidal friction between sliding rock fragments, as it gets deeper.

Water circulates in the core and then rises because it is hotter than the surroundings. This process ultimately transfers heat to the base of the ocean in narrow plumes where it interacts strongly with the rocks. At the seafloor, these plumes vent into the cooler ocean.

One seafloor hotspot alone is predicted to release as much as 5 GW of energy, roughly corresponding to the annual geothermal power consumed in Iceland.

Such seafloor hotspots generate ocean plumes rising at a few centimetres per second. Not only do the plumes result in strong melting of the ice crust above, but they can also carry small particles from the seafloor, over weeks to months, which are then released into space by the icy jets.

Last Enceladus plume observation

Moreover, the authors’ computer models show that most water should be expelled from the moon’s polar regions, with a runaway process leading to hot spots in localised areas, and thus a thinner ice shell directly above, consistent with what was inferred from Cassini.

“Our simulations can simultaneously explain the existence of an ocean at a global scale due to large-scale heat transport between the deep interior and the ice shell, and the concentration of activity in a relatively narrow region around the south pole, thus explaining the main features observed by Cassini,” says co-author Gabriel Tobie, also from the University of Nantes.

The scientists say that the efficient rock–water interactions in a porous core massaged by tidal friction could generate up to 30 GW of heat over tens of millions to billions of years.

“Future missions capable of analysing the organic molecules in the Enceladus plume with a higher accuracy than Cassini would be able to tell us if sustained hydrothermal conditions could have allowed life to emerge,” says Nicolas Altobelli, ESA’s Cassini project scientist.

A future mission equipped with ice-penetrating radar would also be able to constrain the ice thickness, and additional flybys – or an orbiting craft – would improve models of the interior, further verifying the presence of active hydrothermal plumes.

“We’ll be flying next-generation instruments, including ground-penetrating radar, to Jupiter’s ocean moons in the next decade with ESA’s Juice mission, which is specifically tasked with trying to understand the potential habitability of ocean worlds in the outer Solar System,” adds Nicolas.

It has been two years since the digital migration deadline set by the ITU for Africa expired and yet only six African nations have completed digital transition. This slow progress is largely due to the steep challenges faced by countries with a large landmass, mountain ranges or islands that typically remain beyond range of terrestrial network, or with interferences issues in border regions, as well as by the question of funding.

In most cases a terrestrial/satellite solution beats standalone terrestrial in terms of cost effectiveness and speed. Homes within a satellite coverage can receive DTT channels immediately without having to wait for new investment in terrestrial infrastructure and its gradual deployment across a territory.

Digital migration needs to happen now as African countries are missing out on opportunities that include:

  • Transforming the diversity, signal quality and reach of channels into viewer homes.
  • Generating infrastructure upgrades and stimulate Africa’s vibrant content creation industry
  • Releasing analogue frequencies for other applications such as mobile services.
