Ball Aerospace supports PDR for NASA Spherex mission

Ball Aerospace supported the completion of the preliminary design review (PDR) for NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx). With PDR complete, the SPHEREx project will proceed toward critical design review and the project team will now complete the Key Decision Point C process in coordination with NASA prior to beginning the implementation phase.

Ball is responsible for building the spacecraft and telescope as well as system integration and test, support for integration of the spacecraft onto a launch vehicle and commissioning of the spacecraft after launch.

"This latest program milestone is an important step forward in realizing NASA's mission to peer into the history of the universe," said Dr. Makenzie Lystrup, vice president and general manager, Civil Space, Ball Aerospace. "Ball has a long heritage of delivering new and innovative solutions for tomorrow's science questions, partnering with our customers and the science community to provide science at any scale."

The SPHEREx mission will study the nature of physics that drove cosmic inflation in the early universe; determine the properties of interstellar ices, a key reservoir for water and biogenic material in the early phases of star and planet formation; and probe the cosmic history of galaxy formation. Dr. James Bock of the California Institute of Technology (Caltech) is the principal investigator for SPHEREx and NASA's Jet Propulsion Laboratory (JPL) is the managing center.

The SPHEREx bus will be based on the Ball Aerospace customizable and proven line of Ball Configurable Platform (BCP) spacecraft, designed for flexible, cost-effective applications, using a common spacecraft bus and standard payload interfaces to reduce cost, streamline payload accommodation and minimize delivery time. The BCP series has served as the spacecraft for past explorer-class missions such as the Wide-Field Infrared Survey Explorer, or WISE.

Exceeding its spacecraft design life, WISE was later repurposed as NEOWISE after completing its primary mission in order to hunt for near-Earth objects. The BCP for the SPHEREx mission builds on the heritage of the success of WISE/NEOWISE and leverages current investments in the platform resulting in increased performance and reduced cost and schedule.

Next step in simulating the universe
Tsukuba, Japan (SPX) Dec 03, 2020
Computer simulations have struggled to capture the impact of elusive particles called neutrinos on the formation and growth of the large-scale structure of the Universe. But now, a research team from Japan has developed a method that overcomes this hurdle. In a study published this month in The Astrophysical Journal, researchers led by the University of Tsukuba present simulations that accurately depict the role of neutrinos in the evolution of the Universe. Why are these simulations importa ... read more
