Their day began to the tune of Chappell Roan's "Pink Pony Club," before transitioning into their daily activities. At wakeup, the spacecraft and its crew were approximately 169,000 miles from Earth and approaching the Moon at 110,700 miles. Later on Saturday, Glover will take manual control of the spacecraft to test its performance in deep space to provide more data about the spacecraft's handling qualities across different movements. A 24-hour acoustics test also will occur to help engineers characterize the sound environment in the spacecraft. After the piloting demonstration, the crew will review a list of the surface features the NASA science team has asked them to analyze and photograph during their six-hour flyby on Monday. Flight controllers again cancelled a planned outbound trajectory correction burn, as Integrity's trajectory remains on track. The team instead adjusted the spacecraft's attitude to point a vent toward the Sun to help clear a wastewater line. Overnight, controllers vented wastewater overboard to free up space in Orion's waste management system tank, but the activity ended earlier than expected. Engineers have been using the vent heaters to melt any potential ice that may be clogging the line and orienting the vent toward the Sun to help mitigate the issue. Teams also are reviewing other potential causes. The wastewater tank is not full and the toilet is operational; however, the crew was instructed to use backup collection devices overnight if needed. Just after 12 p.m. EDT, the Orion Artemis II Optical Communications System surpassed 100 gigabytes of data downlinked during the mission, including high resolution images. The terminal, mounted on the outside of the Orion capsule, uses laser communications — infrared light — to transmit more data than traditional radiofrequency systems.</blockquote>[/B][/QUOTE]
