NASA’s Aitken supercomputer
provides powerful modeling and simulation capabilities to support
critical research for a safe and successful spaceflight for the
next return-to-moon by 2024
Hewlett Packard Enterprise (HPE) today announced that NASA
highlighted new research progress to support the next human landing
on the moon by performing complex simulations on NASA’s Aitken
supercomputer, which is powered by HPE. New research, which
includes understanding the booster separation event and launch
environment at Kennedy Space Center during lift-off, will help
NASA’s engineers prepare for a safe and successful spaceflight as
part of NASA’s Artemis mission set to launch in 2024.

HPE also announced today that it expanded NASA’s Aitken
supercomputer with HPE Apollo systems that are purpose-built for
compute-intensive modeling and simulation needs. The expansion of
computational power, which will be operational in January 2021,
supports NASA’s ongoing research involving computational fluid
dynamics (CFD) that are critical to understanding aerodynamic
events.
“At HPE, we are inspired by breakthroughs in scientific research
that leverage our high-performance computing technologies. The
researchers and engineers at NASA’s Ames Research Center continue
to push boundaries to advance space flight,” said Bill Mannel, vice
president and general manager, HPC, at HPE. “We are honored to
continue collaborating with NASA and play a role in a historical
moment by further expanding NASA’s Aitken supercomputer with HPE
Apollo systems to accelerate time-to-insight and safely land the
first woman and the next man on the moon.”
NASA’s Aitken Supercomputer Increases Computational Power and
Drives Efficiency

supercomputer is housed, at NASA’s Ames Research Center in Mountain
View, California
NASA’s Aitken supercomputer was built by HPE in August 2019 to
support NASA missions, including research for the Artemis program,
a mission to land the first woman and next man on the lunar South
Pole region by 2024.
NASA’s Aitken is housed in the first of 12 computer modules in
the Modular Supercomputing Facility (MSF), jointly developed by
NASA and HPE, to drive greater efficiency and significantly reduce
electricity and water use. As a result, NASA’s Aitken
supercomputer, during its first year of operation, consumed only
16% of the energy needed for cooling, saving over $100K in costs
and 1.4 million kilowatt-hours. It also reduced water usage, used
to cool the supercomputer, by 91%, saving over one million gallons
of water per day.
The supercomputer will expand with HPE Apollo systems using 2nd
Gen AMD EPYC processors to provide advanced compute power to
support ongoing research.
NASA’s Aitken Supercomputer Advances Research Progress for
Return-to-Moon Mission NASA’s Aitken supercomputer has already
helped researchers make progress for the Artemis mission in the
following areas:
Develop an Aerodynamic Database for Possible Events during
the Artemis Booster Separation NASA’s engineers need to
understand possible events that could occur during booster
separation from the core of the Artemis rocket during liftoff,
which is critical to the safety of the crew and success of the
mission. NASA considers the possibilities that the two solid rocket
boosters (SRBs), developed for the mission, will strike the core
center or each other during the separation event.
To simulate and model all variables during separation events
during the Artemis mission, NASA has developed a database of
aerodynamic data to showcase possible positioning of the boosters
during separation. By applying computational fluid dynamics (CFD)
tools using NASA’s Aitken supercomputer and accounting for 22
different engine rocket plumes, which are moving hot exhaust gases,
researchers were able to develop a database of 13 independent
variables to model all possible in-flight events during booster
separation. The project can be viewed here.
The expansion to NASA’s Aitken supercomputer will enable even
more detailed and comprehensive databases to improve accuracy in
analysis for a safer flight.
Understanding the Launch Environment at the Kennedy Space
Center The Artemis mission is set to launch at the Kennedy
Space Center in Merritt Island, Florida. NASA’s researchers need to
understand the effects of ignition overpressure (IOP) and duct
overpressure (DOP) waves that are caused by the rapid expansion of
gas from the rocket nozzle during launch.
NASA’s Launch, Ascent, and Vehicle Aerodynamics (LAVA) team has
been using NASA’s Aitken supercomputer to apply computational fluid
dynamics (CFD) to simulate these waves and how they interact with
the launch vehicle to examine any potential dangers to the
mission.
The ongoing analysis helps NASA’s engineers make advancements to
the design of the launch environment. With the expanded Aitken
supercomputer, researchers will gain additional compute power to
further improve time-to-solution for the launch pad redesign to
accommodate the Space Launch System. The project can be viewed
here.
