- A mission to Mars will require sophisticated computing capabilities to cut down on communication latencies and ensure astronaut's survival
- In an effort to advance this mission, HPE and NASA launched a supercomputer into space on the SpaceX Dragon Spacecraft
- The Spaceborne Computer is a year-long experiment—roughly the same amount of time it would take to get to Mars—which will test a supercomputers ability to function in the harsh conditions of space
From faster problem solving to astronaut survival, the Spaceborne Computer is the first step in developing sophisticated onboard computing resources
On August 14, 2017, the SpaceX CRS-12 rocket, developed by Elon Musk's SpaceX, launched from Kennedy Space Center, Florida, sending its Dragon Spacecraft to the International Space Station (ISS) National Lab. Aboard the Dragon was a HPE supercomputer.
This supercomputer, called the Spaceborne Computer, is part of a year-long experiment conducted by HPE and NASA to run a high performance commercial off-the-shelf (COTS) computer system in space, which has never been done before. The goal is for the system to operate seamlessly in the harsh conditions of space for one year – roughly the amount of time it will take to travel to Mars.
Advancing the Mission to Mars
Many of the calculations needed for space research projects are still done on Earth due to the limited computing capabilities in space, which creates a challenge when transmitting data to and from space. While this approach works for space exploration on the moon or in low Earth orbit (LEO) when astronauts can be in near real-time communication with Earth, once they travel farther out and closer to Mars, they will experience larger communication latencies. This could mean it would take up to 20 minutes for communications to reach Earth and then another 20 minutes for responses to reach astronauts. Such a long communication lag would make any on-the-ground exploration challenging and potentially dangerous if astronauts are met with any mission critical scenarios that they're not able to solve themselves.
A mission to Mars will require sophisticated onboard computing resources that are capable of extended periods of uptime. To meet these requirements, we need to improve technology's viability in space in order to better ensure mission success. By sending a supercomputer to space, HPE is taking the first step in that direction. Future phases of this experiment will eventually involve sending other new technologies and advanced computing systems, like Memory-Driven Computing, to the ISS once we learn more about how the Spaceborne Computer reacts in space.
Lessons from the Mission to the Moon
When the United States successfully put two men on the moon, it captivated the world and inspired technological advancements from the microchip to memory foam. The mission to Mars is the next opportunity to propel technological innovation into the next frontier. The Spaceborne Computer experiment will not only show us what needs to be done to advance computing in space, it will also spark discoveries for how to improve high performance computing (HPC) on Earth and potentially have a ripple effect in other areas of technology innovation.
HPC in Space
The Spaceborne Computer includes the HPE Apollo 40 class systems with a high speed HPC interconnect running an open-source Linux operating system. Though there are no hardware modifications to these components, we created a unique water-cooled enclosure for the hardware and developed purpose-built system software to address the environmental constraints and reliability requirements of supercomputing in space. Generally, in order for NASA to approve computers for space, the equipment needs to be "ruggedized" – or hardened to withstand the conditions in space. Think radiation, solar flares, subatomic particles, micrometeoroids, unstable electrical power, irregular cooling. This physical hardening takes time, money and adds weight, so HPE took a different approach to "harden" the systems with software. HPE's system software will manage real time throttling of the computer systems based on current conditions and can mitigate environmentally induced errors. Even without traditional ruggedizing, the system still passed at least 146 safety tests and certifications in order to be NASA-approved for space.
A Look Back on 30 Years in Space
Through the SGI acquisition, Hewlett Packard Enterprise has a longstanding, 30-year relationship with NASA. This relationship started the co-development of the world's first IRIX single-system image in 1998. Along the way, we've achieved great milestones, including the co-development of one of the largest and fastest supercomputers, Columbia, a 10,240-processor supercluster that was named the second fastest supercomputer in the world on the 2004 Top500 list. Today, the Spaceborne Computer contains compute nodes of the same class as NASA's premier supercomputer, Pleiades, currently ranked #9 in the world.
We see the Spaceborne Computer experiment as a fitting extension to our HPE Apollo portfolio, purpose-built for supercomputing. HPE is excited to expand its relationship with NASA, pioneering HPC in space and taking one step closer to a mission to Mars.
In addition to working with NASA, this experiment was sponsored by the Center for the Advancement of Science in Space, the organization in charge of managing the ISS U.S. National Laboratory.
