A collaboration between NASA and the Indian Space Research Organisation, NISAR will use synthetic aperture radar to monitor nearly all the planet’s land- and ice-covered surfaces twice every 12 days.Credit: NASA NASA will host a news conference at 12 p.m. EDT Monday, July 21, to discuss the upcoming NISAR (NASA-ISRO Synthetic Aperture Radar) mission.
The Earth-observing satellite, a first-of-its-kind collaboration between NASA and ISRO (Indian Space Research Organisation), carries an advanced radar system that will help protect communities by providing a dynamic, three-dimensional view of Earth in unprecedented detail and detecting the movement of land and ice surfaces down to the centimeter.
The NISAR mission will lift off from ISRO’s Satish Dhawan Space Centre in Sriharikota, on India’s southeastern coast. Launch is targeted for no earlier than late July.
NASA’s Jet Propulsion Laboratory in Southern California will stream the briefing live on its X, Facebook, and YouTube channels. Learn how to watch NASA content through a variety of platforms, including social media.

With its two radar instruments — an S-band system provided by ISRO and an L-band system provided by NASA — NISAR will use a technique known as synthetic aperture radar (SAR) to scan nearly all the planet’s land and ice surfaces twice every 12 days. Each system’s signal is sensitive to different sizes of features on Earth’s surface, and each specializes in measuring different attributes, such as moisture content, surface roughness, and motion.
These capabilities will help scientists better understand processes involved in natural hazards and catastrophic events, such as earthquakes, volcanic eruptions, land subsidence, and landslides.
Additionally, NISAR’s cloud penetrating ability will aid urgent responses to communities during weather disasters such as hurricanes, storm surge, and flooding. The detailed maps the mission creates also will provide information on both gradual and sudden changes occurring on Earth’s land and ice surfaces.
Managed by Caltech for NASA, JPL leads the U.S. component of the NISAR project and provided the L-band SAR. NASA JPL also provided the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Near Space Network, which will receive NISAR’s L-band data.
Multiple ISRO centers have contributed to NISAR. The Space Applications Centre is providing the mission’s S-band SAR. The U R Rao Satellite Centre provided the spacecraft bus. The rocket is from Vikram Sarabhai Space Centre, launch services are through Satish Dhawan Space Centre, and satellite mission operations are by the ISRO Telemetry Tracking and Command Network. The National Remote Sensing Centre is responsible for S-band data reception, operational products generation, and dissemination.

An artist’s concept of the Starlab commercial space station.Starlab As NASA continues its transition toward a commercial low Earth orbit marketplace, an agency-supported commercial space station, Starlab, recently completed five development and design milestones. Starlab’s planned design consists of a service module and a habitat that will be launched to orbit on a single flight.
The milestones, part of a NASA Space Act Agreement awarded in 2021, focused on reviews of Starlab’s preliminary design and safety, as well as spacecraft mockup and procurement plans. Each milestone provides NASA insight into the company’s development progress.
“As we work toward the future of low Earth orbit, these milestones demonstrate Starlab’s dedication to building a commercial space station that can support human life and advance scientific research,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “Both the insight shared by Starlab and the expertise shared by NASA are critical to future mission success.”
Starlab recently completed a preliminary design and safety review of its station’s architecture and systems. The company now will begin detailed design and hardware development, culminating in a critical design review later this year. Critical design reviews are an important step in a station’s development, assessing design maturity before proceeding with fabrication and assembly.
An artist’s concept of the Starlab commercial space station.Starlab Starlab also has begun construction of a full-scale, high-fidelity mockup of the station. The mockup, which will be housed in the Space Vehicle Mockup Facility at NASA Johnson, will be used for human-in-the-loop testing, during which participants perform day-in-the-life walkthroughs and evaluate the interior design, crew training, procedure development, hardware checks, and in-flight issue resolution.
In addition, Starlab completed reviews of the system design architecture, procurement plan, and Northrop Grumman Cygnus spacecraft docking system design. In 2023, Northrop Grumman teamed up with Starlab to provide cargo logistics services and engineering consultation to support the commercial space station. These reviews included design configuration updates of solar arrays, docking ports, crew quarters, and more.
NASA supports the design and development of multiple commercial space stations through funded and unfunded agreements. Following the design and development phase, NASA plans to procure services from one or more companies as part of its strategy to become one of many customers for low Earth orbit stations.

Video: 00:00:40 View of Earth as seen by ESA project astronaut Sławosz Uznański-Wiśniewski inside the seven-windowed cupola, the International Space Station's "window to the world".
The European Space Agency-built Cupola is the favourite place of many astronauts on the International Space Station. It serves not only as a unique photo spot, but also for observing robotic activities of the Canadian Space Agency's robotic arm Canadarm2, arriving spacecraft and spacewalks.
Sławosz was launched to the International Space Station on the Dragon spacecraft as part of Axiom Mission 4 on 25 June 2025. The 20-day mission on board is known as Ignis.
During the Ignis mission, Sławosz conducted 13 experiments proposed by Polish companies and institutions and developed in collaboration with ESA, along with three additional ESA-led experiments. These covered a broad range of areas including human research, materials science, biology, biotechnology and technology demonstrations.
The Ax-4 mission marks the second commercial human spaceflight for an ESA project astronaut. Ignis was sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT) and the Polish Space Agency (POLSA).

A host of scientific investigations await the crew of NASA’s SpaceX Crew-11 mission during their long-duration expedition aboard the International Space Station. NASA astronauts Zena Cardman and Mike Fincke, and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, are set to study plant cell division and microgravity’s effects on bacteria-killing viruses, as well as perform experiments to produce a higher volume of human stem cells and generate on-demand nutrients.
Here are details on some of the research scheduled during the Crew-11 mission:
Making more stem cells
Cultures of stem cells grown in 2D on Earth, left, and as 3D spheres in simulated microgravity on Earth.BioServe A stem cell investigation called StemCellEx-IP1 evaluates using microgravity to produce large numbers of induced pluripotent stem cells. Made by reprogramming skin or blood cells, these stem cells can transform into any type of cell in the body and are used in regenerative medicine therapies for many diseases. However, producing enough cells on the ground is a challenge.
Researchers plan to use the microgravity environment aboard the space station to demonstrate whether generating 1,000 times more cells is possible and whether these cells are of higher quality and better for clinical use than those made on Earth. If proven, this could significantly improve future patient outcomes.
“This type of stem cell research is a chance to find treatments and maybe even cures for diseases that currently have none,” said Tobias Niederwieser of BioServe Space Technologies, which developed the investigation. “This represents an incredible potential to make life here on Earth better for all of us. We can take skin or blood cells from a patient, convert them into stem cells, and produce custom cell-therapy with little risk for rejection, as they are the person’s own cells.”
Alternative to antibiotics
Genes in Space-12 student investigators Isabella Chuang, left, and Julia Gross, middle, with mentor Kayleigh Ingersoll Omdahl.Genes in Space Genes in Space is a series of competitions in which students in grades 7 through 12 design DNA experiments that are flown to the space station. Genes in Space-12 examines the effects of microgravity on interactions between certain bacteria and bacteriophages, which are viruses that infect and kill bacteria. Bacteriophages already are used to treat bacterial infections on Earth.
“Boeing and miniPCR bio co-founded this competition to bring real-world scientific experiences to the classroom and promote molecular biology investigations on the space station,” said Scott Copeland of Boeing, and co-founder of Genes in Space. “This
investigation could establish a foundation for using these viruses to treat bacterial infections in space, potentially decreasing the dependence on antibiotics.”
“Previous studies indicate that bacteria may display increased growth rates and virulence in space, while the antibiotics used to combat them may be less effective,” said Dr. Ally Huang, staff scientist at miniPCR bio. “Phages produced in space could have profound implications for human health, microbial control, and the sustainability of long-duration remote missions. Phage therapy tools also could revolutionize how we manage bacterial infections and microbial ecosystems on Earth.”
Edible organisms
A purple, pre-incubation BioNutrients-3 bag, left, and a pink bag, right, which has completed incubation, on a purple and pink board used for comparison.NASA Some vitamins and nutrients in foods and supplements lose their potency during prolonged storage, and insufficient intake of even a single nutrient can lead to serious diseases, such as a vitamin C deficiency, causing scurvy. The BioNutrients-3 experiment builds on previous investigations looking at ways to produce on-demand nutrients in space using genetically engineered organisms that remain viable for years. These include yogurt and a yeast-based beverage made from yeast strains previously tested aboard station, as well as a new, engineered co-culture that produces multiple nutrients in one sample bag.
“BioNutrients-3 includes multiple food safety features, including pasteurization to kill microorganisms in the sample and a demonstration of the feasibility of using a sensor called E-Nose that simulates an ultra-sensitive nose to detect pathogens,” said Kevin Sims, project manager at NASA’s Ames Research Center in California’s Silicon Valley.
Another food safety feature is a food-grade pH indicator to track bacterial growth.
“These pH indicators help the crew visualize the progress of the yogurt and kefir samples,” Sims said. “As the organisms grow, they generate lactic acid, which lowers the pH and turns the indicator pink.”
The research also features an investigation of yogurt passage, which seeds new cultures using a bit of yogurt from a finished bag, much like maintaining a sourdough bread starter. This method could sustain a culture over multiple generations, eliminating concerns about yogurt’s shelf life during a mission to the Moon or Mars while reducing launch mass.
Understanding cell division
Cells of green algae dividing.University of Toyama The JAXA Plant Cell Division investigation examines how microgravity affects cell division in green algae and a strain of cultured tobacco cells. Cell division is a fundamental element of plant growth, but few studies have examined it in microgravity.
“The tobacco cells divide frequently, making the process easy to observe,” said Junya Kirima of JAXA. “We are excited to reveal the effects of the space environment on plant cell division and look forward to performing time-lapse live imaging of it aboard the space station.”
Understanding this process could support the development of better methods for growing plants for food in space, including on the Moon and Mars. This investigation also could provide insight to help make plant production systems on Earth more efficient.
For nearly 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and conducting critical research for the benefit of humanity and our home planet. Space station research supports the future of human spaceflight as NASA looks toward deep space missions to the Moon under the Artemis campaign and in preparation for future human missions to Mars, as well as expanding commercial opportunities in low Earth orbit and beyond.
