Northrop Grumman’s supplier delivers to the International Space Station – now for space flight



NASA officials wrote in a fact sheet: “Long-term personnel exploration missions require a water recovery rate of about 98%, and there is currently no latest technology in salt water treatment that can help achieve this goal.” The processor system plans to close the gap in the urine flow of the space station.”

The Cygnus mission will also provide a new sleeping area for the seven-person crew of the space station. Currently, the US portion of the US space station has five crew members. Four astronauts flew to SpaceX’s “Crew Dragon” capsule outpost in November, and astronaut Kate Rubens arrived on the Russian Soyuz spacecraft in October.

But there are only four sleeping stations in the US. Astronaut Mike Hopkins of the Crew Dragon mission sleeps in the SpaceX capsule docked on the space station.

Other hardware inside the Cygnus supply ship includes spare parts and support equipment for the space station toilet, and air tanks used to replenish the breathable atmosphere inside the space laboratory.

5 mission will study how microgravity affects the manufacture of protein-based artificial retinas. Nicole Wagner, President and CEO of LambdaVision, stated that the experiment was led by a Connecticut startup called LambdaVision. The experiment is a follow-up to the space station survey conducted in 2018, which produced “very encouraging “the result of.

The company uses a “layer-by-layer” process to manufacture artificial retinas that can be implanted in patients suffering from retinal degenerative diseases.

Jordan Greco, Chief Scientific Officer of LambdaVision, said: “This is the second of many flights we expect (to the space station).” “This particular layered experiment allows us to continue to gather key information about the system design and continue Explore the impact of microgravity on this layering process.”

“What we are sending on NG-15 is to send protein materials. In fact, we will make artificial retinas on the ISS. So we do this process layer by layer on the International Space Station, and then put these movies back on Earth for analysis,” Wagner said.

Wagner said that with NASA funding, LambdaVision is seeking to extend the layer manufacturing process to other applications besides artificial retinas.

According to Wagner, the retinal implant developed by LambdaVision can restore “high-resolution vision” for patients by replacing the functions of light-sensitive rods and cones inside the eye. The artificial retina is composed of light-activated proteins.

Greco said: “We are delighted to have the opportunity to produce products in low Earth orbit that will bring real clinical benefits to patients, and in our case, provide a basis for patients who have turned a blind eye to this devastating retinal degeneration disease. .”

The researchers moved the CubeLab that contains the new LambdaVision study, which evaluated a manufacturing system that uses light-activated proteins to replace the function of damaged cells in the eye in artificial retinas.

Another experiment of the NG-15 mission will measure the muscle strength of multiple generations of worms (including animals raised in space). Humans lose their power during long space flights, but scientists hope to better understand the biological changes caused by microgravity.

Siva Vanapalli, professor of chemical engineering at Texas Tech University and lead researcher of the experiment, said: “In order to understand biology, our project focuses on capturing these…worms and studying how the intensity of these worms changes. “

The experiment was started with 1,000 worm larvae, which will grow during the mission. According to Wanapali, these worms will multiply their offspring in space.

A new device called NemaFlex will continuously measure the muscle strength of worms. Vanapalli said: “If we do observe that our equipment can record these intensity changes, it will open up huge opportunities for experimenting with different drugs and figuring out how to maintain and improve the health of astronauts.”

Cygnus delivered high-performance commercial off-the-shelf computers from Hewlett-Packard to the space station. According to NASA, engineers will test the computer’s ability to process scientific data in space, which may allow researchers to obtain faster results from their experiments.

The cargo mission also carries a radiation detector, which will fly on NASA’s Orion spacecraft. The National Aeronautics and Space Administration said that the successful test of the radiation monitor on the space station will verify that the device can perform the Orion Orion second manned Orion mission Artemis 2 to the moon for the first time in 2023.

The cargo ship in Cygnus carries several small nanosatellites that will be released into orbit in the next few months.

The Gunsmoke-J technology demonstration satellite is a 3U CubeSat of the US Army Space and Missile Defense Command, designed to prove the practicality of ground imaging payloads in military combat force tactics.

The Army said in a press release last year: “This scientific and technological effort will provide tactical fighters with new and advanced capabilities through a small satellite the size of a loaf of bread.” “This work will also help Provide a basis for future acquisition decisions.”

The Gunsmoke-J satellite and two other small satellites for unspecified US government customers were launched in the pressurized cabin of the Cygnus spacecraft. Before the spacecraft leaves the International Space Station later this year, astronauts will place these satellites on the railway deployment plane in the Swan hatch to separate the cargo plane after it leaves the airport.

Spaceflight, a ride-sharing launch agent based in Seattle, arranged launch services for Gunsmoke-J and two other US government satellites.

There are also several other CubeSats on the Cygnus freighter. One is called IT-SPINS, which will collect images of the Earth’s late-night ionosphere during a six-month research mission. The IT-SPINS CubeSat is about the size of an oven and was developed at Montana State University.

The students of Abu Dhabi Khalifa University developed a CubeSat called DhabiSat. Students developed the CubeSat with the help of Abu Dhabi’s communications satellite companies Yahsat and Northrop Grumman.

Paraguay’s first satellite, the CubeSat called Guarani Satellite 1, was also launched on Saturday. The Paraguay Space Agency stated that CubeSat was developed in cooperation with Japanese engineers and Paraguayan universities and research centers.
