NASA Composite Booms Deploy, Mission Sets Sail in Space

NASA’s Advanced Composite Solar Sail System is now fully deployed in space after a successful test of its sail-hoisting boom system. Mission operators confirmed success at 1:33 p.m. EDT (10:33 a.m. PDT) on Thursday, Aug. 29, after receiving data from the spacecraft. Centrally located aboard the spacecraft are four cameras which captured a panoramic view of the reflective sail and supporting composite booms. High-resolution imagery from these cameras will be available on Wednesday, Sept. 4. 

During the next few weeks, the team will test the maneuvering capabilities of the sail in space. Raising and lowering the orbit of the Advanced Composite Solar Sail System spacecraft will provide valuable information that may help guide future concepts of operations and designs for solar sail-equipped science and exploration missions. 

The Advanced Composite Solar Sail System spacecraft orbits Earth at approximately twice the altitude of the International Space Station. From above, the sail will appear as a square, with an area of approximately 860 square feet (80 square meters) – about half the size of a tennis court. Now, with the sail fully extended, the Solar Sail System may be visible to some keen skywatchers on Earth who look up at the right time.

NASA Updates Deployment Efforts for Solar Sail Demonstration

NASA’s Advanced Composite Solar Sail System has begun deployment operations. Upon an initial attempt to unfurl, the solar sail paused when an onboard power monitor detected higher than expected motor currents. Communications, power, and attitude control for the spacecraft all remain normal while mission managers work to understand and resolve the cause of the interruption by analyzing data from the spacecraft.

One of the primary objectives of this technology demonstration is to test the expanding boom system, which has never been deployed for a solar sail on a spacecraft of this size. The spacecraft’s booms, which are similar in function to a sailboat’s booms, are made of a new material that is stiffer and lighter than previous designs. This technology has the potential to lower the cost of deep space missions and increase access to space.

Mission operators have been able to download data from the spacecraft during brief, planned communications windows when it passes in range of mission control at Santa Clara University in California. The team is conducting analysis and assessing all spacecraft systems before resuming deployment operations.

NASA’s Small Spacecraft Technology program maintains a philosophy of risk tolerance in its pursuit to rapidly mature space technologies that meet the needs of NASA and the nation.

NASA’s Solar Sail System Readies Sail Deployment

Commissioning is nearly complete for NASA’s Advanced Composite Solar Sail System, and mission operators are charting a course for their next milestone – hoisting the sails using new composite booms.

The sail will unfurl from the spacecraft’s 12-unit (12U) CubeSat body using composite booms made from new materials that are stiffer and lighter than previous designs. Once successful boom and sail deployment are achieved, the team hopes to prove the sail’s propulsion capabilities and maneuverability by raising and lowering the satellite’s orbit. Solar sails use the pressure of sunlight for propulsion, as photons bouncing off a reflective sail push a spacecraft. Like a sailboat turning to capture the wind, the spacecraft can adjust its orbit by angling the sail.

After launching in April aboard Rocket Lab’s Electron rocket from New Zealand, the mission completed a series of tests and preparations, including testing two-way communications and deploying solar panels – a battery-charging mechanism, not to be confused with the not-yet deployed solar sail.

The project team expects to deploy the sail in the next few weeks. Given its position in orbit, about 600 miles (1,000 kilometers) above Earth, and the reflectivity of the large sail, about 860 square feet (80 square meters), mission managers say the Solar Sail System should be easily visible at times in the night sky once the sail is fully deployed.

Ahoy! NASA’s Solar Sail Mission Successfully Phones Home

NASA’s Advanced Composite Solar Sail System has now connected with ground operators following its April 23 launch aboard Rocket Lab’s Electron rocket. The satellite is on its way to testing next-generation solar sail technology, which uses the power of sunlight to propel a spacecraft. The results from this mission will advance future space travel to expand our understanding of our Sun and solar system.

The spacecraft was successfully delivered to a type of low Earth orbit called a Sun-synchronous orbit. All systems show that the spacecraft is operational and healthy. Last night at 11:30 p.m. PDT (2:30 a.m. EDT), the microwave oven-sized CubeSat passed over the ground hub located at Santa Clara University’s Robotics Systems Lab in Santa Clara, California, and the mission team confirmed successful two-way communications.

Next, the CubeSat will undergo a one- to two-month commissioning phase to prepare for the solar sail deployment and maneuvering test. At this time, the sail remains within the body of the CubeSat. The mission operations team will set a date to unfurl the sail after all commissioning tasks have been completed. Once ready, the spacecraft will unroll it solar sail via four booms that span the diagonals of the square and unspool to reach 23 feet (about 7 meters) in length.

NASA’s Starling CubeSats Succeed in Early Space Navigation Test

NASA’s Starling mission accomplished a significant objective for the StarFOX (Starling Formation-Flying Optical Experiment) experiment, a test of autonomous navigation, co-location, and situational awareness in space.

Using downlinked images from onboard “star tracker” sensors, the team used ground-based software to demonstrate StarFOX’s ability to autonomously differentiate the background field of stars and other orbiting spacecraft from fellow members of the Starling swarm.

The spacecraft captured one photo every minute, and despite inconsistencies in illumination and minimal relative motion, the software was able to use the angular positions of the other Starling satellites within those images to estimate their orbits accurately with respect to GPS measurements captured during the test.

The next step is to demonstrate this software in orbit with similar results, autonomously correcting orbit predictions over time as each photo provides more data about the trajectory of spacecraft in the swarm.

StarFOX is being led by the Stanford University’s Space Rendezvous Laboratory.

Communications Achieved for NASA’s Four Starling CubeSats

Mission managers have established command communications with all four of NASA’s Starling CubeSats! The spacecraft are progressing through payload and propulsion tests, the final stage of a pre-operations checklist called commissioning.

The Starling spacecraft – which project team members nicknamed Blinky, Pinky, Inky, and Clyde – are part of an ambitious test to develop self-coordinating robotic swarms for space research and exploration.

Progress so far has been as expected for three of the four spacecraft – Pinky, Inky, and Clyde. An initial communication issue with Blinky was addressed by updating estimates of its orbital position and instructing the satellite to better align its antennas with ground station receivers. Operators have achieved operational two-way communications with all Starling units and are still investigating the root cause of the issue.

In addition, data analysis of Blinky’s onboard attitude control system, which manages the spacecraft’s orientation, showed that it was having to work to counteract a disturbance. Initial troubleshooting suggested this was likely connected to a propulsion system leak, which was subsequently remediated. Operators are working to better understand the issue and how it might impact the mission.

After this final stage of commissioning, the Starling spacecraft will begin a procedure called a “drift arrest maneuver,” adjusting the orbital positions of each craft to bring them into proper alignment to begin testing swarm activities.
