FOR IMMEDIATE RELEASE
STOTTLER HENKE WINS CONTRACT TO DEVELOP SOFTWARE
FOR SCHEDULING ASTRONAUT ACTIVITIES ABOARD NEXT-GENERATION SPACECRAFT
United Space Alliance awards Stottler Henke $300,000 project
SAN MATEO, Calif., March 23, 2006 –
The United Space Alliance (USA) has engaged Stottler
Henke Associates, Inc. (www.stottlerhenke.com)
to develop an in-flight version of its
Aurora intelligent scheduling software
for proposed use on board the United States’ next-generation
manned spacecraft. The system is designed to be used by astronauts to schedule their activities
on the Crew Exploration Vehicle (CEV), due to launch in 2008.
USA is a joint venture of Boeing Co. (NYSE: BA) and Lockheed Martin Corp. (NYSE: LMT)
responsible for all human space flight operations in the United States. Stottler Henke received a
13-month, $300,000 development contract from USA.
Stottler Henke’s Aurora software will be an integral part of Temporis, a system USA is creating
to streamline an extremely complex scheduling process with myriad constraints and
dependencies. Using Temporis, astronauts themselves for the first time will be able to schedule
all aspects of their in-flight lives – routine daily activities, space craft housekeeping, and
conducting on-board experiments.
USA’s human spaceflight planning operations experience on the Shuttle and International
Space Station programs have positioned USA to master future mission complexity. USA
understands that scheduling activities aboard the CEV will be a multi-dimensional challenge
because the spacecraft’s communication, power and motion at any given moment dictates what
can or cannot be done on board at that time. For example, activities that require voice or data
communication – such as some experiments and spacecraft maneuvers, or the crew’s daily
medical consultation – depend on having a line of sight between the ship’s antenna and a
communications relay satellite, which in turn depends on the CEV’s attitude and point in its
trajectory. Similarly, certain astronomical observations require precise positioning of the ship.
On the other hand, microgravity experiments require absolutely no spacecraft motion other than
free float, nor any vibrations. Therefore, during those experiments, astronauts cannot use the
ship’s thrusters to control its position – and they can’t even use the exercise bike.
“Temporis is a crucial piece of software that will enable the President’s Vision for Space
Exploration,” Christopher Leslie, a senior mission planner at USA, said. “We are very excited
about the prospect of devising a highly automated way of accomplishing this scheduling in-flight,
by leveraging the work Stottler Henke already has done with Aurora.”
Currently in use at NASA at the Kennedy Space Center, Aurora is a sophisticated scheduling
system that combines a variety of scheduling techniques, intelligent conflict resolution, and
decision support to make Shuttle ground process scheduling faster and easier. The software’s
scheduling decisions take into account resource requirements, a variety of constraints, and any
pertinent domain knowledge.
Once Aurora has created a schedule, it displays it in a series of graphical images that allow the
user to see the scheduled activities, resource allocations and the temporal relationships among
the activities. This display also allows the user to edit the schedule directly, intuitively, and
The new version of Aurora for Temporis will feature a flexible Java API (application
programming interface) that allows GUI (graphical user interface) developers to easily specify
activities, resources and constraints in Aurora. During scheduling, Aurora returns time and
resource assignment updates through the API, along with any conflicts that were generated.
The API allows astronauts to easily override the scheduler's decisions. In addition to the API for
GUI developers, the scheduling engine also allows programmers to plug in new, custom
scheduling logic modules.
“Scheduling activities aboard the CEV that must satisfy complex resource and task constraints
is precisely the type of challenge that Aurora is extremely well suited to handle,” Richard
Stottler, president of Stottler Henke Associates, said. “We look forward to collaborating with
USA to create the Temporis system, freeing up resources on the ground and empowering
astronauts to be more self-reliant on future missions.”
