Northrop Grumman S.S. Richard “Dick” Scobee
NASA selected Richard Scobee as an astronaut in 1978. Scobee flew as a pilot of STS 41-C and was the commander of STS 51-L. The STS 51-L crew, including Scobee, died on January 28, 1986, when space shuttle Challenger exploded after launch.NASA Arrival & Departure
The Cygnus spacecraft will arrive at the orbiting laboratory on Monday, Aug. 5, filled with supplies, hardware, and critical materials to directly support dozens of scientific and research investigations during Expeditions 71 and 72. NASA astronaut Matthew Dominick will capture Cygnus using the station’s robotic arm, and NASA astronaut Jeanette Epps will act as backup.
After capture, the spacecraft will be installed on the Unity module’s Earth-facing port and will spend almost six months connected to the orbiting laboratory before departing in January 2025. Cygnus also provides the operational capability to reboost the station’s orbit.
Live coverage of Cygnus’ arrival will begin at 2:30 a.m. Aug. 5 on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website.
NASA astronauts Matthew Dominick and Jeanette Epps will be on duty during the Cygnus spacecraft’s approach and rendezvous. Dominick will be at the controls of the Canadarm2 robotic arm ready to capture Cygnus as Epps monitors the vehicle’s arrival.NASA Research Highlights
Scientific investigations traveling in the Cygnus spacecraft include tests of water recovery technology and a process to produce blood and immune stem cells in microgravity, studies of the effects of spaceflight on engineered liver tissue and microorganism DNA, and live science demonstrations for students.
Gravitational Effects on Filtration Systems
The Packed Bed Reactor Experiment: Water Recovery Series evaluates gravity’s effects on eight additional test articles.NASA The Packed Bed Reactor Experiment: Water Recovery Series investigates how gravity affects two-phase flow or simultaneous movement of gas and liquid through porous media. Teams will evaluate eight different test articles representing components found in the space station’s water processor or urine processor to understand two-phase flows for both liquid and gas in microgravity.
Packed bed reactors are structures that use “packing” of objects, usually pellet-like catalysts, of various shapes and materials to increase contact between different phases of fluids. These systems are used for a variety of applications such as water recovery, thermal management, and fuel cells, and the experiment develops a set of guidelines and tools to optimize their design and operation for water filtration and other systems in microgravity and on the Moon and Mars. Insights from the investigation also could lead to improvements in this technology for applications on Earth such as water purification and heating and cooling systems.
Balloon Sounds in Space
The Office of STEM Engagement’s Next Gen STEM Project, STEMonstrations, that will demonstration the effects centripetal force has on sounds during spaceflight.NASA’s Office of STEM Engagement STEMonstrations, as part of NASA’s Next Gen STEM (science, technology, engineering, and mathematics) Project, are performed and recorded by astronauts on the space station. Each NASA STEMonstration illustrates a different scientific concept, such as centripetal force, and includes resources to help teachers further explore the topics with their students.
Astronauts will demonstrate centripetal force on the space station using a penny, a hexnut, and two clear balloons. The penny and the hexnut are whirled inside of the inflated balloon to compare the sounds made in a microgravity environment.
Cell Production on Station
The production of blood and immune stem cells on the space station with the BioServe In-Space Cell Expansion Platform (BICEP).NASA In-Space Expansion of Hematopoietic Stem Cells for Clinical Application (InSPA-StemCellEX-H1) tests hardware to produce human hematopoietic stem cells (HSCs) in space. HSCs give rise to blood and immune cells and are used in therapies for patients with certain blood diseases, autoimmune disorders, and cancers.
Researchers use BioServe In-Space Cell Expansion Platform, a stem cell expansion bioreactor designed to expand the stem cells three hundredfold without the need to change or add new growth media.
Someone in the United States is diagnosed with a blood cancer about every three minutes. Treating patients with transplanted stem cells requires a donor-recipient match and long-term repopulation of transplanted stem cells. This investigation demonstrates whether expanding stem cells in microgravity could generate far more continuously renewing stem cells.
Spaceflight Effects on DNA
The Rotifer-B2 investigation on the Internation Space Station explores the effects of spaceflight on DNA (deoxyribonucleic acid) repair mechanisms.ESA (European Space Agency) Rotifer-B2, an ESA (European Space Agency) investigation, explores how spaceflight affects DNA (deoxyribonucleic acid) repair mechanisms in a microscopic organisms called bdelloid rotifer, or Adineta vaga. These tiny but complex organisms are known for their ability to withstand harsh conditions, including radiation doses 100 times higher than human cells can survive.
Researchers culture rotifers, microorganisms that inhabit mainly freshwater aquatic environments, in an incubator facility on the space station. After exposure to microgravity conditions, the samples provide insights into how spaceflight affects the rotifer’s ability to repair sections of damaged DNA in a microgravity environment and could improve the general understanding of DNA damage and repair mechanisms for applications on Earth.
Bioprinting Tissue
The Maturation of Vascularized Liver Tissue Construct in Zero Gravity (MVP Cell-07) investigation used to conduct bioprinting of tissue on the space station. NASA Maturation of Vascularized Liver Tissue Construct in Zero Gravity (MVP Cell-07) examines engineered liver tissue constructs that contain blood vessels. Researchers aim to learn more about the progression of tissue and development of blood vessels in engineered tissues on the space station.
The experiment observes how bioprinted liver tissue behaves in space and whether microgravity causes changes in cell shape, size, and volume. The formation of tissue structures and vascular linings also are studied to ensure proper structure generation in orbit. Bioprinting in microgravity may enable the manufacturing of high-quality tissues and organs that are difficult to maintain on the ground, which could help advance space-based production of tissues and functional organs to treat patients on Earth.
Cargo Highlights
SpaceX’s Falcon 9 rocket will launch the Northrop Grumman Cygnus spacecraft to the International Space Station.
NASA’s Northrop Grumman 21st commercial resupply mission will carry more than 8,500 pounds (3,856 kilograms) of cargo to the International Space Station.NASA Hardware

Preparations for Next Moonwalk Simulations Underway (and Underwater)
HyAxiom’s 440-kilowatt phosphoric acid fuel cell is now its flagship product, and it still builds on technical know-how developed under the Apollo and space shuttle programs.Credit: HyAxiom Inc. NASA’s investment in fuel cells dates to the 1960s when most of the world was still reliant on fossil fuels. A fuel cell generates electricity and heat when hydrogen and oxygen bond through an electrolyte. Because its only by-product is water, it’s an environmentally friendly power source.
The agency’s interest in fuel cells came when NASA needed to fuel missions to the Moon. Engineers at NASA’s Johnson Space Center in Houston looked to fuel cells because they could provide more energy per pound than batteries could over the course of a long mission. At that time, fuel cells were just a concept that had never been put to practical use.
NASA funded development of the first practical fuel cells because they were necessary to cut weight from the Apollo spacecraft for Moon missions. Three fuel cells in the Apollo service module provided electricity for the capsule containing the astronauts. The division of Pratt & Whitney that made the fuel cells later became UTC Power, now a subsidiary of Doosan Group known as HyAxiom Inc.Credit: NASA NASA funded three companies, including a portion of Pratt & Whitney, to develop prototypes. For Apollo mission fuel cells, NASA selected the Pratt & Whitney group, which soon became UTC Power, as the supplier of all the space shuttle fuel cells. With the agency funding and shaping its technology development, UTC Power eventually started offering commercial fuel cells. The company is now known as HyAxiom Inc. and operates from the same plant in South Windsor, Connecticut, that produced fuel cells for the agency.
The company released its first commercial fuel cell in the mid-1990s and introduced its current product line about a decade later.
“The models they built for these products we use today had a lot of the electrochemistry understanding from the space program,” said Sridhar Kanuri, HyAxiom’s chief technology officer.
HyAxiom now produces around 120 units per year but expects to ramp up as government investments in fuel cells increase. The U.S. government plans to use fuel cells to store energy from renewable sources.
Today’s commercial fuel cell companies received much of their knowledge base from NASA. John Scott, NASA’s principal technologist for power and energy storage said, “All these companies trace their intellectual property heritage, their corporate heritage, even the generations of personnel to those companies NASA funded back in the early 1960s.”
