Dragon capsule returns to Earth after Space station delivery

A SpaceX Dragon freight send left the International Space Station and came back to Earth Saturday (Jan. 13), wrapping up an about month-long conveyance mission for NASA that likewise denoted the rocket’s second trek to space.

The uncrewed Dragon supply transport isolates from the space station’s mechanical arm at 4:58 a.m. EST (0958 GMT) and started terminating thrusters for its arrival to Earth. The space container sprinkled down in the Pacific Ocean off the bank of Baja California to be recovered by SpaceX, the organization reported at 10:39 a.m. EST (1539 GMT).

“Great splashdown of Dragon affirmed, finishing the second resupply mission to and from the @Space_Station with a flight-demonstrated business rocket,” SpaceX delegates said in a Twitter refresh.

Mythical serpent is conveying about 4,100 lbs. (1,860 kilograms) of payload to Earth, a lot of it science outfit from human and creature inquire about, and different investigations. That rigging incorporates equipment from an analysis by space producing organization Made In Space to 3d-print ZBLAN glass fiber optic wire in space, and a gathering of live mice from NASA’s Rodent Research 6 concentrate to create prescriptions that address muscle misfortune in space., NASA authorities said.

A SpaceX Falcon 9 rocket propelled the Dragon mission on Dec. 15, with the container landing at the International Space Station on Dec. 17. The mission, SpaceX’s thirteenth resupply flight for NASA, conveyed 4,800 lbs. (2,177 kilograms) of provisions and rigging for space travelers.

Notwithstanding conveying freight, the mission denoted a turning point for SpaceX’s rocket reusability program. Both the Dragon case and its Falcon 9 promoter made their second treks to space on this flight. The Falcon 9 sponsor’s first stage already propelled an alternate Dragon container to the space station in June 2017. The Dragon case on this flight, in the mean time, beforehand went by the space station in April 2015.

December 22, 2014 in Mission Reports: Ratchet wrench 'emailed' to space station

A future where mission control can digitally dispatch tools, spare parts and other vital materials to far-flung space crews took one giant leap toward reality when a 3D printer aboard the International Space Station produced a ratchet wrench on demand.

The 3D printer has been on the space station since it launched on an automated SpaceX supply ship in September, printing test coupons designed to prove the device functions in the weightless environment more than 200 miles above Earth.

On Dec. 17, engineers took the demonstrations a step further, uplinking a custom-made digital design file of a ratchet wrench to a laptop attached to the printer.

The ratchet is the first “uplink tool” produced by the 3D printer, according to Made in Space, a Silicon Valley startup that partnered with NASA to build and test the machine.

So far, the printer has only made things that were designed before it launched and tested on an identical machine on the ground. The ratchet produced Dec. 17 is an “uplink tool” that was designed, qualified, tested and printed in space in less than a week, according to Made in Space.

“The ‘uplink’ is the way we communicate with the ISS crew using a transmitting frequency from Earth to the International Space Station,” Made in Space wrote in a blog post. “Therefore an uplink tool refers to a tool design that was transmitted to the space station via the uplink and manufactured on-demand in space.”

The 3D printer works by extruding a special type of hot plastic — known as acrylonitrile butadiene styrene, or ABS — into layers to form a three-dimensional object. Engineers can upload the specifications of the finished product to the printer’s computer controller, which oversees the unit’s production.

Made in Space engineer Noah Paul-Gin created the ratchet design on Autodesk Inventor, a computer-aided design application, at the company’s ground station in California.

“During the rapid prototyping process, Noah realized that rounded edges and finger grooves on the handle would make the tool more ergonomic and improve the grip,” Made in Space said in a blog post. “The ratchet was designed as one print with moveable parts without any support material. The parts and mechanisms of the ratchet had to be enclosed to prevent pieces from floating in the microgravity environment.”

When Made in Space was satisfied with the design, they sent the file to NASA for a safety check. NASA then emailed the socket wrench’s specs to a laptop connected to the 3D printer.

The wrench took about four hours to print, Made in Space officials said. It will not be used by the astronauts but will be returned to Earth for inspection and analysis to see how the 3D printer in space compares to the performance of an exact copy of the device on the ground.

Astronaut Barry “Butch” Wilmore displayed the finished ratchet wrench in a photo sent back to Earth.

The demo printer does not require much attention by the astronauts, who only need to set up the system and remove the printed part at the end of the process.

Assuming the testbed works, a second 3D printer is on track for liftoff to the space station next year. It will be available for use by NASA, international space agencies and commercial users, according to Jason Dunn, co-founder and chief technology officer of Made in Space.

Aaron Kemmer, another Made in Space co-founder, tweeted Sunday that the company has completed the design phase of the second 3D printer.

For future missions into deep space — where supply lines with Earth may be thin — astronauts could use 3D printers to manufacture spare parts.

3D printing in space would avoid putting parts through the intense shaking and noise of launch, and it could allow engineers to design and build components on the fly as parts break down in space.

Future printers could manufacture whole structures for CubeSats, tools, medical gear, exercise equipment and other items to keep the space station operating.

“It’s especially important when we consider human space exploration,” said Niki Werkheiser, NASA’s manager for the 3D Printing in Zero-G project. “From day one, the supply chain has been very constrained. We have to launch every single thing we ever need from Earth, so being able to make what you need on orbit — when you need it — is a real game changer.”

3D Printing Comes To International Space Station

Astronauts on the ISS successfully manufactured a part (for the printer) earlier this week.

There is little use in arguing the merits and usefulness of the 3D printer in myriad uses. That is not to say they don’t curry the occasional bit of controversy when someone puts the blueprints for a 3D printed gun on the Internet. A gun that could in theory avoid standard metal detectors. The International Space Station astronauts, however, are not printing weapons in space but on Monday were able to manufacture a faceplate for the printhead on the machine that printed the item in microgravity.

International Space Station: Man’s first tool (in space)

“When the first human fashioned a tool from a rock, it couldn’t have been conceived that one day we’d be replicating the same fundamental idea in space,” said Made In Space CEO Aaron Kemmer. “We look at the operation of the 3D printer as a transformative moment, not just for space development, but for the capability of our species to live away from Earth.”

While most essential equipment arrives at the International Space Station with the necessary spare parts, additional parts need to be shipped from Earth and that is rarely two-day delivery even for astronauts whom happen to have Amazon Prime memberships. Rather, re-supply missions are both expensive and few and far between.

“This project demonstrates the basic fundamentals of useful manufacturing in space. The results of this experiment will serve as a stepping stone for significant future capabilities that will allow for the reduction of spare parts and mass on a spacecraft, which will change exploration mission architectures for the better,” said Made In Space Director of Research and Development Mike Snyder, also principal investigator for the experiment. “Manufacturing components on demand will yield more efficient, more reliable and less Earth dependent space programs in the near future.”

Tests to help next model printer

The “Glovebox” 3D printer is Made In Space’s first effort and astronauts will be asked to print a variety of tools, parts, and test coupons. Following their completion, they will be sent back to Earth where they will be compared to items made on Earth by the same printer. Made in Space will also test these items for torque, strength, accuracy and other factors and use the results to build the next generation printer that it will send to the ISS next year.
