FLIGHT SUMMARY
The Galactic 7 flight take a look at aboard Virgin Galactic’s VSS Unity despatched two college payloads — from the College of California, Berkeley and Purdue College — on suborbital flight exams supported by NASA’s Flight Alternatives program. The reusable suborbital spaceship reached an altitude of greater than 54 miles and supplied roughly three minutes of microgravity. These circumstances supplied analysis groups the chance to guage a brand new 3D printer’s in-space efficiency and to review of how the sloshing of liquid propellant impacts spacecraft pointing.

“To deal with essential capabilities wanted for house exploration, researchers should advance their applied sciences as rapidly as potential. Our program permits them to quickly transfer from the lab to flight take a look at, and in lots of instances a number of flight exams throughout totally different automobiles. This permits them the invaluable alternative to study from preliminary exams, implement enhancements, after which fly once more.”

The phrase “do me a strong” has new that means on the subject of in-space manufacturing.
Concerning the Payload
Relatively than printing in layers, UC Berkeley’s new additive manufacturing system makes use of mild to solidify liquid and gel supplies in a single step in microgravity. The suborbital flight take a look at supplied a possibility to mature this expertise for future use in crewed house exploration missions or producing industrial merchandise in low Earth orbit.
Collectively developed by the UC Berkeley and Lawrence Livermore Nationwide Laboratory, the multi-material manufacturing method is named computed axial lithography.
Purposes
The space-based model goals to quickly meet astronauts’ pressing wants. These would possibly vary from printing spare elements for spacecraft equipment to addressing medical-related points throughout long-duration missions. The expertise may even be used to bioprint organs in low Earth orbit for sufferers on Earth.
“We’re seeking to print a spread of issues in house, from mechanical engineering instruments to clips for closing wounds,” stated principal investigator Hayden Taylor. “We’re additionally wanting into restorative dental functions. So, if an astronaut chips a tooth on a protracted mission and we have now a scan of their mouth, this machine may print a crown on demand.”
Flight Check Targets
Working with the Conseil Nationwide de Recherches Canada, Taylor and the remainder of the analysis workforce are striving to scale back the scale and cycle time of in-space additive manufacturing programs and enhance the standard of printed items. Their different objectives embrace minimizing the required stage of operator expertise whereas rising scalability and modularity. Additionally they wish to supply new capabilities, similar to embedding an present merchandise inside a 3D printed object.
Flight Testing Heritage
The flight with Virgin Galactic builds on two earlier UC Berkeley exams, which Flight Alternatives additionally supported. Throughout parabolic flights aboard Zero Gravity Company’s G-Drive One plane, researchers experimented with printing numerous objects throughout 20-second rounds of diminished gravity. They leveraged the outcomes of these flight exams to regulate their method, enhance {hardware} and knowledge assortment, and combine the post-processing often carried out individually to complete a printed piece.

Researchers look at how sloshing propellant impacts spacecraft pointing.
Concerning the Payload
Researchers designed this expertise to assemble knowledge which will result in exact steering, navigation, and management (GNC) fashions of liquid response and ship reduced-gravity measurements to replace present fashions.
Purposes
Spacecraft pointing maneuvers orient a automobile for docking or Earth reentry and assist optimize the operations of imaging satellites orbiting the Earth, Moon, and Mars. Speedy, correct pointing maneuvers require advance data of the time wanted for propellant sloshing to settle to a small enough stage.
Flight Check Targets
Since exact modeling of slosh in microgravity will not be potential computationally or by way of testing on Earth, the measurements made throughout this flight take a look at with Virgin Galactic might be used to assist plan spacecraft actions extra exactly, thereby rising spaceflight operational security and gasoline effectivity.
