REQUEST FOR INFORMATION (RFI)
The Centennial Challenges Program is NASA’s flagship program for technology prize competitions (www.nasa.gov/challenges). The Centennial Challenges Program directly engages the public, academia, and industry in open prize competitions to stimulate innovation in technologies that have benefit to NASA and the nation. The program is an integral part of NASA’s Space Technology Mission Directorate, which is innovating, developing, testing, and flying hardware for use in NASA’s future missions. For more information about NASA’s Space Technology Mission Directorate, visit: http://www.nasa.gov/spacetech .
The Centennial Challenges program is seeking input on a Space RACE challenge being considered for start in 2015. The challenge would require competitors to build vehicles capable of autonomous rendezvous, capture, and manipulation of small objects at high speeds with applications for the Mars Sample Return campaign, lunar sample return missions, and many other commercial venues.
The purposes of this RFI are: 1) to gather feedback on the competition being considered, 2) to determine the level of interest in potentially competing in this challenge, and 3) to understand the applicability of the technology developed by the competition for other non-government applications.
NASA welcomes replies to this RFI from all segments of industry, academia, and government, including associations, innovators, and enthusiasts. This RFI is for informational/planning purposes only and the Government will not be responsible for any cost associated with preparing information in support of this RFI. This RFI is NOT to be construed as a commitment by the government to enter into any agreement or other obligation, or to conduct a Space RACE (Rendezvous And Capture Experiment) challenge. This notice is issued in accordance with the NASA Prize Authority, 51 U.S.C. § 20144. Responses may be made available for public review and should not include proprietary information. Submitted information will be shared within NASA and with contractor personnel associated with the NASA Centennial Challenges Program. All responses are for general access by government reviewers.

On-orbit sample capture, a special application of Autonomous Rendezvous and Docking (AR&D), poses several difficult challenges. These include close-range on-orbit detection, rendezvous, and capture of a very small, passive space object (<20cm diameter). While there have been several successful AR&D flight systems (e.g., Space Shuttle, Orbital Express, XSS-11, and SpaceX Dragon), a compact and standardized solution for the retrieval of very small passive objects has yet to be demonstrated. Development of a standard on-orbit sample capture/return spacecraft bus would not only enable NASA missions such as Mars Sample Return and lunar sample return, but also minimize the cost of and the risks to future missions. The architecture of the Space RACE competition would spark meaningful technical advancements in dynamic tracking, capture, and precision manipulation of small objects, challenges common to both space and terrestrial applications (such as automated packaging and fruit picking). Space RACE would encourage collaborative innovation between space research and commercial fields.
III. CHALLENGE DESCRIPTION
The competition would simulate the autonomous rendezvous, capture, and manipulation of an Orbiting Sample (OS) around Mars or the moon in the form of a head-to-head competition. Competitors would build a vehicle capable of tracking a simulated OS moving around a flat, circular track at 6 m/s, rendezvousing with it, capturing it, and depositing it in a provided “Earth Return Vehicle” (ERV), all without any off-board systems. They would then face other competitors in head-to-head matches that consist of two rounds each. In each round, competitors would first obtain a stable “parking orbit” at a “high altitude” towards the outside of the track, 180 degrees apart from the other competitor. A circular reference line taped to the track at this radius, as well as an angular reference would be provided to assist competitors in reaching this starting state.
Once both competitors are in their parking orbit, a robotic vehicle (referred to as the “OS Bot”) would be “launched” from the inside of the track into a parking orbit lane at a lower altitude (smaller radius as compared to the competitor’s orbit) carrying two OS’s mounted on front and rear booms, one for each competitor. The OS Bot would insert itself into orbit exactly halfway between each competitor and at a constant speed (4 m/s in the first level of the competition, 6 m/s in the second level). Competitors’ vehicles would then race to rendezvous, capture, and store their OS in their ERVs, with a small caveat: after the OS is launched, vehicles must remain in a specified speed band of +/- 0.5 m/s of the OS Bot’s speed. This would force competitors to change radii to either catch up with or slow down to the OS Bot, simulating orbital mechanics. Competitor’s speed, acceleration, and power consumption would be monitored by a provided regulation package, most likely based on ranging radio technology and IMUs, and the ERV would be a container with an OS shaped depression in it requiring control of position and orientation for successful storage of the OS. The first competitor to accomplish all the above tasks successively would win that round. The second round would be the same as the first, except that the competitors would switch starting positions (fore and aft of the OS Bot).
The OS would be a small white cylinder with reflective fiducial stripes on its surface to assist competitors with tracking. It would be magnetically mounted on its corner in an asymmetric manner and, in the second level of competition, rotated at a constant rate of 4 RPM. The magnets would be tuned such that if a competitor impacts the OS, it would fall away from the mount and the competitor would be disqualified from that round.
IV. DRAFT CHALLENGE RULES AND COMPETITION STRUCTURE
The competition would be run in two successive levels with increasing difficulty:
1. Level 1 a. OS platform moving at 4m/s b. OS not rotating 2. Level 2 a. OS platform moving at 6m/s b. OS rotates at 4RPM
Within each level, teams would be expected to produce a functioning robot for two phases:
1. Qualifying Round a. Successfully demonstrate the following tasks three consecutive times: i. Static grasping of OS ii. Ability to maintain parking orbit. Robot platform must maintain the correct radius and angular position, as specified by the references. 2. Head to Head a. Two rounds per match, each round lasting a maximum of 5 minutes. b. Minimum total time from GO signal to successful placement of OS in Earth Return Vehicle across both rounds c. Each team would be randomly seeded to compete in three matches each over the course of a day, but guaranteed not to have back-to-back matches. A five minute setup period would take place between the two rounds in a match, and a ten minute setup period would take place between each match. Time results of all matches accumulate for each team to assign rankings; teams with lower overall times would be ranked higher. From these rankings, the top six teams would be selected to compete in a single elimination tournament taking place on the subsequent day.
Tentative Rules and Regulations – These are tentative suggestions for the rules and regulations of the competition and are entirely open to suggestions for changes.
