Preparations for Next Moonwalk Simulations Underway (and Underwater)

Researchers are testing a laser communications networking system that could enable the public to watch the first woman and first person of color walk on the Moon in HD during the Artemis missions.
The media availability begins at 11 a.m. EDT on Tuesday, July 30 (weather permitting) at the NASA Glenn aircraft hangar. Media will have the opportunity to see NASA’s Pilatus PC-12 aircraft take off and to film researchers on the ground as they communicate with the airborne team.
During these tests, researchers flying over Lake Erie will test communications between NASA Glenn and the aircraft using High-Rate Delay Tolerant Networking developed by Glenn. The data is transferred over laser communications links at a rate of 1.2 gigabits per second — faster than most home internet speeds.
Earlier this summer, the research team streamed 4K video to the International Space Station from an aircraft for the first time in history.
Media interested in attending should contact Jan Wittry at jan.m.wittry-1@nasa.gov by 2 p.m. EDT on Monday, July 29.
These experiments are part of NASA’s goal to stream very high-bandwidth video and other data from deep space, enabling future human missions beyond Earth orbit. In December, NASA streamed a video featuring a cat named Taters back to Earth from nearly 19 million miles away in deep space using NASA’s laser communications demonstration, marking a historic milestone.
About Laser Communications
Historically, missions have relied on the use of radio waves to exchange information to and from space. Now, NASA is embracing the power of laser communications, also known as optical communications, which uses infrared light rather than radio waves to transmit more data at once.
As NASA explores the lunar surface with advanced science instruments and captures high-definition data, researchers will need faster ways to send large amounts of information to Earth. Laser communications will accelerate the data transfer process and enable 10 to 100 times more data transmitted back to Earth than current radio frequency systems.

Preparations for Next Moonwalk Simulations Underway (and Underwater)

The feat was part of a series of tests on new technology that could provide live video coverage of astronauts on the Moon during the Artemis missions.
Historically, NASA has relied on radio waves to send information to and from space. Laser communications use infrared light to transmit 10 to 100 times more data faster than radio frequency systems.

Credit: NASA/Sara Lowthian-Hanna Working with the Air Force Research Laboratory and NASA’s Small Business Innovation Research program, Glenn engineers temporarily installed a portable laser terminal on the belly of a Pilatus PC-12 aircraft. They then flew over Lake Erie sending data from the aircraft to an optical ground station in Cleveland. From there, it was sent over an Earth-based network to NASA’s White Sands Test Facility in Las Cruces, New Mexico, where scientists used infrared light signals to send the data.
The signals traveled 22,000 miles away from Earth to NASA’s Laser Communications Relay Demonstration (LCRD), an orbiting experimental platform. The LCRD then relayed the signals to the ILLUMA-T (Integrated LCRD LEO User Modem and Amplifier Terminal) payload mounted on the orbiting laboratory, which then sent data back to Earth. During the experiments, High-Rate Delay Tolerant Networking (HDTN), a new system developed at Glenn, helped the signal penetrate cloud coverage more effectively.

4K video footage was routed from the PC-12 aircraft to an optical ground station in Cleveland. From there, it was sent over an Earth-based network to NASA’s White Sands Test Facility in Las Cruces, New Mexico. The signals were then sent to NASA’s Laser Communications Relay Demonstration spacecraft and relayed to the ILLUMA-T payload on the International Space Station.

Aeronautics testing of space technology often finds issues more effectively than ground testing, while remaining more cost-effective than space testing. Proving success in a simulated space environment is key to moving new technology from a laboratory into the production phase.
“Teams at Glenn ensure new ideas are not stuck in a lab, but actually flown in the relevant environment to ensure this technology can be matured to improve the lives of all of us,” said James Demers, chief of aircraft operations at Glenn.
The flights were part of an agency initiative to stream high-bandwidth video and other data from deep space, enabling future human missions beyond low Earth orbit. As NASA continues to develop advanced science instruments to capture high-definition data on the Moon and beyond, the agency’s Space Communications and Navigation, or SCaN, program embraces laser communications to send large amounts of information back to Earth.
The optical system temporarily installed on the belly of the PC-12 aircraft has proven to be a very reliable high-performance system to communicate with prototype flight instrumentation and evaluate emerging technologies to enhance high-bandwidth systems.Credit: NASA/Sara Lowthian-Hanna While the ILLUMA-T payload is no longer installed on the space station, researchers will continue to test 4K video streaming capabilities from the PC-12 aircraft through the remainder of July, with the goal of developing the technologies needed to stream humanity’s return to the lunar surface through Artemis.

Video: 00:02:00 While no person could get this close during Ariane 6’s inaugural flight on 9 July 2024, several small cameras bravely witnessed its take-off from the launchpad.
After years of preparations, the Vulcain main stage engine ignites, arms providing cryogenic fuels to the rocket until the very last moment retract and boosters fire – Ariane 6 is space-bound. As it lifts off, vast amounts of water are pumped at high speed to dampen vibrations at the launch site, which then come rushing towards one of these small cameras in a dramatic swirl, hiding the departing rocket from view.
Ariane 6 launched from Europe's Spaceport in French Guiana at 16:00 local time (20:00 BST, 21:00 CEST), designed to provide more launch power with higher flexibility and at a lower cost than its predecessors. The launcher’s configuration – with an upgraded main stage, a choice of either two or four powerful boosters and a new restartable upper stage – will provide Europe with greater efficiency and a wider range of launch services, including for the launch of multiple payloads into different orbits on a single flight.

Video: 03:04:20 Europe’s new rocket Ariane 6 powered Europe into space taking with it a varied selection of experiments, satellites, payload deployers and reentry demonstrations that represent thousands across Europe, from students to industry and experienced space actors.
This inaugural flight, designated VA262, is a demonstration flight to show the capabilities and prowess of Ariane 6 in escaping Earth's gravity and operating in space. Nevertheless, it had several passengers on board.
Ariane 6 was built by prime contractor and design authority ArianeGroup. In addition to the rocket, the liftoff demonstrated the functioning of the launch pad and operations on ground at Europe's Spaceport. The new custom-built dedicated launch zone was built by France's space agency CNES and allows for a faster turnover of Ariane launches.
Ariane 6 is Europe’s newest heavy-lift rocket, designed to provide great power and flexibility at a lower cost than its predecessors. The launcher’s configuration – with an upgraded main stage, a choice of either two or four powerful boosters and a new restartable upper stage – will provide Europe with greater efficiency and possibility as it can launch multiple missions into different orbits on a single flight, while its upper stage will deorbit itself at the end of mission.
ESA’s main roles in the Ariane 6 programme is as contracting authority – managing the budget from Member States participating in the Ariane 6 development programme; and as launch system architect – ensuring that the rocket and launch pad infrastructure work together.
Ariane 6 is the latest in Europe's Ariane rocket series, taking over from Ariane 5 featuring a modular and versatile design that can launch missions from low-Earth orbit and farther out to deep space.
