Mini-radar for asteroid CubeSat

by European Space Agency
October 31, 2022

A 10-cm box will make history as the smallest radar instrument to
be flown in space—and the very first radar to probe the interior
of an asteroid. Its target? The Dimorphos asteroid, which on the
night of 26 September had its orbit diverted and a vast 10,000 km
plume sent out into space by collision with NASA's DART mission.

This radar instrument, connected to a quartet of 1.5 m-long
antenna booms, will be flown aboard the aircraft-carry-on-sized
Juventas CubeSat, which will in turn be flown to Dimorphos aboard
ESA's Hera spacecraft, due to be launched in two years' time.

Hera—currently taking shape at OHB in Germany and Avio in
Italy—will fly to Dimorphos to perform a close-up survey of the
aftermath of the DART impact, gathering key information such as
the size of DART's crater, the mass of Dimorphos as well as its
make-up and internal structure. Hera's extra data will help turn
the DART deflection experiment into a well-understood, repeatable
technique that might one day be needed for real.

And in fact, Hera is not one spacecraft but three: it carries
with it ESA's first deep-space CubeSats to make extra
observations of its asteroid target. The radar-hosting Juventas
will be accompanied by Milani, which will survey the composition
of Dimorphos's surface and dust.

This "JuRa" instrument is a miniaturized version of the radar
flown aboard ESA's Rosetta comet mission and used to probe
beneath the black surface of comet 67P/Churyumov–Gerasimenko. It
was developed by Dr. Alain Hérique's group at the Institut de
Planétologie et d'Astrophysique de Grenoble (IPAG) at the
Université Grenoble Alpes and Dr. Dirk Plettemeier's group at
Technical University Dresden, together with Emtronix in
Luxembourg responsible for manufacturing the instrument.

From TechXplore:

Used batteries from electric vehicles are put to good use by a
new energy storage system in San Diego

by Rob Nikolewski
San Diego Union-Tribune via TechXplore
October 26, 2022

At a nondescript office park in the Mira Mesa neighborhood of San
Diego sit a pair of nondescript cubes, adjacent to a nondescript
library annex that houses old books, papers and other items from
UC San Diego.

But something different is happening. Inside each cube sits a
collection of used electric vehicle batteries—one containing
Tesla batteries and the other stocked with old batteries from
Nissan Leafs.

While these lithium-ion batteries once powered cars that are no
longer on the road, they still have plenty of lifespan left in
them. A local company with connections to the university has
taken what would usually be discarded and found a novel way to
reuse them.

Mike Ferry, president of Smartville, Inc., points to the
building's roof.

"You can't see it, but there's a huge rooftop solar array up
there and that array overproduces (electricity) during the day,"
Ferry said on a hot, sunny day last week. "We're now taking that
excess and during the critical peak (time for California's grid),
from 4 to 9 p.m. when the sun goes down, we discharge that energy
back into the library and we power the building."

It sounds simple and while other companies are working with
repurposed batteries, the Smartville energy storage system—called
MOAB—combines two different battery packs into a single system.

"That's never been done before," Ferry said. "Our technology is
able to integrate battery packs, not only in different states of
health and different histories but actually from different
manufacturers (Tesla and Nissan) and control them in a reliable
way."

MOAB originally stood for Modular Assembly Battery system but is
now the trademarked brand name for Smartville's technology.

The system also collects data that can predict precisely how long
the batteries are going to last.

"This is energy storage that's using batteries that otherwise are
going to be wasted," said Antoni Tong, Smartville's CEO. "So
there are huge social and environmental implications."

In addition to supplying power to the annex between 4 to 9 p.m.,
MOAB also can provide emergency backup during power outages.

The warehouse holds a collection of books, physical items and
even manuscripts from Jonas Salk, developer of one of the first
polio vaccines and founder of the Salk Institute for Biological
Studies in La Jolla.

The archives require constant humidity and temperature controls
to avoid damage. The new energy storage system can provide the
annex up to 48 hours of electricity if a blackout or energy
emergency cuts off the building's power.

"I have a sneaking suspicion that results of this ongoing
research will end up in our collections, possibly even within
this very warehouse and help to drive future innovations," Jason
Schulz, UC San Diego's Director for Library Services, said during
the project's unveiling last Wednesday.

The MOAB system in Mira Mesa is relatively small—just 500
kilowatt-hours, or one-half a megawatt-hour. For comparison,
SDG&E's Kearny Energy Storage battery facility delivers
80-megawatt-hours of energy via batteries housed in 126 cubes.

Smartville has garnered $9 million in funding to develop its
system, which has been enough to cover the company's budget and
payroll for 15 employees who work at Smartville's headquarters in
Carlsbad. The company has received money from the U.S. Department
of Energy and two grants of $2 million each from the California
Energy Commission.

"This project is filling a very important kind of hole in the
mosaic" for California to achieve its clean energy goals, said
energy commission chair David Hochschild. Reusing EV batteries
for energy storage is "exactly what the state needs."

More MOAB systems are in the pipeline—a 1 to 4 megawatt-hours
project in Fresno; a 0.25 megawatt-hour system at Nissan's U.S.
headquarters in Franklin, Tenn.; and another 0.25 MWh project in
Atlanta with Southern Power. Smartville also has a small
demonstration project in Chula Vista.

Storage has taken on a higher profile in recent years, especially
in California, as the state increasingly relies on renewable
energy sources.

Production from solar and wind has ramped up but they are
intermittent.

Solar production may be abundant during the day but practically
vanishes after sunset or when smoke and clouds obscure the skies.
And when breezes flag, production from wind farms peters out.
Natural gas can help fill the gap but it's a fossil fuel and
California has set a target to derive 100 percent of its
electricity from sources that don't emit carbon by 2045.

Energy storage is seen as a difference-maker, storing up solar
power during the day and discharging electricity later, when
California's power system needs need it.

In 2019, only about 200 megawatts of storage could be found on
California's grid. This year, the numbers have grown to about
3,600 MW and the energy commission projects that 49,000 MW of
battery storage will be needed to meet California's 2045 target.

Battery storage has its critics, who say the systems are more
expensive than conventional energy sources and doubt whether
battery projects can scale to the orders of magnitude and hours
of duration required to meet decarbonization targets. Fires have
also broken out at some battery storage facilities.

"It's all about applications," Tong said. "There's technology in
the pipeline and it's also within the capability of the solution
we are providing here. Each of the (MOAB cubes) are about a
quarter-megawatt-hour in size but when you daisy-chain them, they
can provide a longer duration of discharge. And with the
projection of cost reductions, we can fill that market as well."

In addition to being Smartville's CEO, Tong is a research
scientist at UC San Diego. Ferry is also the director of Energy
Storage & Systems at the university's Center for Energy Research.
UC San Diego has an equity stake in Smartville, Inc.
