Cubesats Offered Deep-Space Ride on ESA Asteroid Probe
European Space Agency
26 February 2015

Think of it as the ultimate hitchhiking opportunity: ESA is offering CubeSats
a ride to a pair of asteroids in deep space.

CubeSats are among the smallest types of satellites: formed in standard
cubic units of 10 cm per side, they provide affordable access to space
for small companies, research institutes and universities. One-, two-
or three-unit CubeSats are already being flown.

Teams of researchers and companies from any ESA Member State are free
to compete. The selected CubeSats will become Europe's first to travel
beyond Earth orbit once the Asteroid Impact Mission (AIM) is launched
in October 2020.

"AIM has room for a total of six CubeSat units," explains Ian Carnelli,
managing the mission for ESA. "So potentially that might mean six different
one-unit CubeSats could fly, but in practice it might turn out that two
three-unit CubeSats will be needed to produce meaningful scientific return.

"We're looking for innovative ideas for CubeSat-hosted sensors that will
boost and complement AIM's own scientific return.

"We also intend to use these CubeSats, together with AIM itself and its
asteroid lander, to test out intersatellite communications networking.

"ESA's SysNova initiative will be applied to survey a comparatively large
number of alternative solutions, this competition framework giving industry
and universities the opportunity to work together on developing their
scientific investigations in a field that is the technological cutting
edge."

Beginning its preliminary Phase-A/B design work next month, ESA's AIM
spacecraft will be humanity's first mission to a binary system - the paired
Didymos asteroids, which come a comparatively close 11 million km to Earth
in 2022. The 800 m-diameter main body is orbited by a 170 m moon.

Asteroid Impact Mission

AIM will perform high-resolution visual, thermal and radar mapping of
the moon. It will also put down a lander - ESA's first touchdown on a
small body since Rosetta's Philae landed on a comet last November.

AIM also represents ESA's contribution to a larger international effort,
the Asteroid Impact & Deflection Assessment (AIDA) mission.

The NASA-led Double Asteroid Redirection Test (DART) probe will impact
the smaller body, while AIM will perform detailed before-and-after mapping,
including pinpointing any shift in the asteroid's orbit.

"While it will return invaluable science," adds Ian, "AIM is conceived
as a technology demonstration mission, testing out various technologies
and techniques needed for deep space expeditions in future.

"These include two-way high-bandwidth optical communications - with data
being returned via laser beam to ESA?s station in Tenerife - as well as
intersatellite links in deep space and low-gravity lander operations.

"Once demonstrated, these capabilities will be available to future deep-space
endeavours, such as Lagrange-point observatories returning large amounts
of data and sample return missions to Phobos - and ultimately Mars - as
well as crewed missions far beyond Earth orbit."

The chance to put forward CubeSats is being organised as a SysNova competition,
an initiative by ESA's General Studies Programme - which is running the
AIM project - to compare innovative solutions to space mission challenges.

Interested teams can get more information from the published announcement
of opportunity. As a next step, qualified teams can submit initial "challenge
responses" describing their proposed mission concepts and how they address
the defined technical challenges associated with operating such small
spacecraft close to an asteroid.

The winning submissions will then be funded by ESA for further study over
the next seven months, following up with a final review at ESA's ESTEC
technical centre in Noordwijk, the Netherlands. The victors will then
work with ESA to elaborate their designs, including sessions at ESTEC's
Concurrent Design Facility.
