Processing of the large solar arrays built for NASA’s Europa Clipper is now underway inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida. 

Planned to arrive at Jupiter in April 2030, the spacecraft will study Jupiter’s moon Europa, which shows strong evidence beneath its icy crust of a global ocean over twice the volume of all Earth’s oceans. Europa is currently considered one of the most promising habitable environments in our solar system.

Once processing of the first five-panel solar array is complete, technicians will remove it from the gravity offload fixture, which helps support the weight of the array. The same steps will then be repeated with the second solar array. Built by Airbus in Leiden, Netherlands, the arrays arrived at Kennedy late last month by truck, after travelling to the U.S. by air. 

When both solar arrays are installed and deployed on Europa Clipper – the agency’s largest spacecraft ever developed for a planetary mission – the spacecraft will span a total length of more than 100 feet and weigh 7,145 pounds without the inclusion of propellants. The spacecraft needs the large solar arrays to collect enough light to power it as it operates in the Jupiter system, which is more than five times as far from the Sun as Earth. 

Europa Clipper is being assembled at NASA’s Jet Propulsion Laboratory in Southern California and is managed in partnership with Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The spacecraft will ship to Florida later this year for launch aboard a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.

As NASA prepares to return to the Moon through Artemis, teams at the agency’s Kennedy Space Center in Florida are working to send much smaller life forms to space to help scientists better understand the effects of space radiation before humans return to the lunar surface.

A number of science experiments, including the agency’s Biology Experiment-1 (BioExpt-1), will be flying on board Artemis I – the mission that will test the agency’s Space Launch System (SLS) rocket and Orion as an integrated system before sending astronauts to the Moon.

NASA’s Space Biology Program selected four biology experiments to fly as part of BioExpt-1, which involves using plant seeds, fungi, yeast, and algae to study the effects of space radiation before sending humans to the Moon and, eventually, to Mars.

“Each of these four experiments will help us understand a unique aspect of how biological systems can adapt and thrive in deep space,” said Sharmila Bhattacharya, NASA program scientist for space biology. “Gathering information like this and analyzing it after flight will eventually help us paint the full picture of how we can help humans thrive in deep space.”

During Artemis I, Orion will travel more than 40,000 miles beyond the Moon, passing through the Van Allen Belts – areas beyond low-Earth orbit where cosmic radiation is trapped – and providing researchers with a true deep space environment for conducting these experiments.

“We don’t currently know what the effects of radiation are outside of low-Earth orbit and how that could affect our system and our biology,” said Dinah Dimapilis, NASA project manager. “I’m excited to see what we can learn from these experiments, to see us go back to the Moon, and to know that I get to be a part of all of this.”

The four experiments will be split into two science bags fabricated and assembled by personnel with the Test Operations and Support Contract at Kennedy. About three weeks before launch, each science bag will be carefully placed into container assemblies built by a team with the Florida spaceport’s Laboratory Support Services and Operations Contract and then secured to the backbone of Orion.

When Orion finishes its journey and splashes down in the Pacific Ocean, each of the experiments will be returned to the principal investigators for further study. Those principal investigators were awarded grants from NASA Biological and Physical Sciences, totaling approximately $1.6 million. The awardees are Federica Brandizzi, Ph.D., Michigan State University; Timothy Hammond, Ph.D., Institute for Medical Research, Inc.; Zheng Wang, Ph.D., Naval Research Laboratory; and Luis Zea, Ph.D., University of Colorado, Boulder.

Final Call for NASA’s RASSOR Bucket Drum Challenge

The Regolith Advanced Surface Systems Operations Robot (RASSOR) is in the regolith bin inside Swamp Works at NASA's Kennedy Space Center in Florida.
A team from the Granular Mechanics and Regolith Operations Lab tests the Regolith Advanced Surface Systems Operations Robot (RASSOR) in the regolith bin inside Swamp Works at NASA’s Kennedy Space Center in Florida on June 5, 2019. Tests use a gravity assist offload system to simulate reduced gravity conditions found on the Moon. On the surface of the Moon, mining robots like RASSOR will excavate the regolith and take the material to a processing plant where usable elements such as hydrogen, oxygen and water can be extracted for life support systems. RASSOR can scoop up icy regolith, which can be used to make operations on the Moon sustainable. Photo credit: NASA/Kim Shiflett

There is still time to submit an entry to NASA’s Regolith Advanced Surface Systems Operations Robot (RASSOR) Bucket Drum Design Challenge. Entries are due by 11:59 p.m. EDT Monday, April 20. A total of $7,000 will be awarded for the top five submissions.

NASA is holding a competition for participants to design an improved bucket drum for RASSOR, a robotic platform designed to dig on the Moon. RASSOR’s current design has counter-rotating bucket drums mounted on moveable arms positioned on either end of the robot. As the bucket drums rotate and start to dig, the forces balance out. This means RASSOR is well suited for excavating in low gravity, because it does not have to rely on its weight or traction to dig.

To enter the competition, go to the GrabCAD website that hosts the challenge and submit an original design with CAD files and a short description of how the design works. The competition is open to eligible individuals.

The challenge is funded by NASA’s Lunar Surface Innovation Initiative within the Space Technology Mission Directorate (STMD), which champions technologies needed to live on and explore the Moon supporting NASA’s Artemis program, which will land the first woman and next man on the Moon. NASA Tournament Lab, part of STMD’s Prizes and Challenges program, manages the challenge. The program supports the use of public competitions and crowdsourcing as tools to advance NASA R&D and other mission needs.

Plant Experiment Veg-03 H Initiated on Space Station

Canadian astronaut David Saint-Jacques began growing two new crops aboard the International Space Station on Saturday, March 9, 2019.
Canadian astronaut David Saint-Jacques initiated plant experiment Veg-03 H aboard the International Space Station on Saturday, March 9, 2019. This required Saint-Jacques to add water to “plant pillows,” which are space pots for plants that contain pre-packed seeds, granular media for the roots to grow into, controlled-release fertilizer, and a way for the on-orbit gardeners to water their plants in microgravity. The experiment should take 30 days to complete and will provide data on food safety for the new crops to compare to ground studies in order to establish a baseline.

Canadian astronaut David Saint-Jacques began growing two new crops aboard the International Space Station on Saturday, March 9, 2019. The two crops, Wasabi Mustard Greens and Extra Dwarf Pak Choi, are part of experiment Veg-03 H. Saint-Jacques placed six “plant pillows” into the veggie growth chamber. This experiment is part of ongoing research on the space station and on Earth to identify fresh vegetables capable of providing astronauts food and nutrition during long-duration spaceflight, including future missions to the Moon or Mars.

Each pillow serves as a pot designed for space with pre-packed seeds, a substance for the roots to grow into, controlled-release fertilizer, and a way for the in-orbit gardeners to water their plants in microgravity.

High school and middle school students participating in the Fairchild Tropical Botanic Garden’s Growing beyond Earth Challenge identified Extra Dwarf Pak Choi as a potential candidate crop for space through classroom science experiments, along with Dragoon Lettuce, which NASA astronaut Serena Auñón-Chancellor grew on the station last fall. Using science stations designed to mimic conditions on the space station gave students a chance to grow plants and record data that NASA was able to use. Those experiments culminated in the plant species which launched to the space station aboard the 15th SpaceX cargo resupply mission on June 29, 2018, along with three other plant species.

The experiment should take 30 days to complete and will provide data on food safety for the new crops to compare to ground studies in order to establish a baseline.

“I think the astronauts will be surprised to learn that the Extra Dwarf Pak Choi that they grow and eat has the same amount of Vitamin C by weight as does a fresh Florida orange,” said NASA scientist Matt Romeyn, “and the leaves don’t taste much different than other fresh leafy greens.”
