Stewart Island/Rakiura is the third-largest island in New Zealand, diminutive in comparison to the country’s North Island and South Island. Yet it hosts a population of one of the largest of the kiwi: the Stewart Island tokoeka. This flightless bird, a subspecies of the Southern brown kiwi (Apteryx australis), numbers in the thousands on the island, dwarfing its human population of approximately 500.

The avian national icon is just one slice of the natural riches on Stewart Island/Rakiura, a roughly triangular piece of land about 30 kilometers (19 miles) south of the South Island. Rakiura National Park covers about 85 percent of the bright green island. And as the Māori name—Rakiura, meaning “glowing skies”—suggests, it’s a prime location for viewing the aurora australis.

On the northern half of the island, podocarp and hardwood forests featuring coniferous trees with ancient lineages blanket the land. Other areas are covered in shrublands and wetlands, as well as coastal dunes such as those lining Mason Bay. A diversity of birdlife, including the kiwi, populates these relatively untouched ecosystems. The tall trees of the podocarp forests produce various fruits attractive to avian inhabitants, such as bellbirds, with their pure-toned calls, and the rare kākāpō, the world’s heaviest and only flightless parrot species.

One notable haven for birds lies on Ulva Island, located within the inlet near Halfmoon Bay (Oban). Rats, which once preyed on bird eggs and chicks there, were deemed eradicated in 1997, and the island has mostly remained free of non-native predators. Conservationists have since embarked on a project on the much larger Stewart Island/Rakiura to eliminate rats, possums, feral cats, and hedgehogs.

When darkness falls, Stewart Island/Rakiura’s human denizens can look skyward for the chance to observe stars, auroras, nearby dwarf galaxies, and other features of the Southern Hemisphere night sky. In 2019, the remote and sparsely inhabited island was designated an International Dark Sky Sanctuary.

Amateur astronomers there and in other places with good night-sky views might search for objects of interest through Hubble’s Night Sky Challenge. In May, when this image was acquired, targets imaged by NASA’s Hubble Space Telescope that were also visible from Earth’s southern latitudes included a star cluster called the Jewel Box and a peculiar elliptical galaxy known as Centaurus A, which may have resulted from two galaxies colliding.

Crew Conducts Futuristic Workouts, Advanced Eye Exams During Spacewalk Preps

Crew Conducts Futuristic Workouts, Advanced Eye Exams During Spacewalk Preps

ESA (European Space Agency) astronaut and Expedition 74 flight engineer Sophie Adenot smiles for a portrait while showing off an Optical Coherence Tomography machine, a medical imaging device used for eye exams. Doctors on the ground monitor the eye exam in real-time viewing an astronaut's retina, lens, and cornea. Vision is critical to a mission’s success and doctors regularly check the astronauts’ eyes to counteract the potential effects of living in space.

Futuristic workouts, eye exams, and virtual reality led the research schedule for the Expedition 75 crew aboard the International Space Station on Wednesday. Spacewalk training and lab maintenance filled the rest of the shift for the seven orbital residents.

Living in weightlessness speeds up muscle and bone loss since it takes much less effort for an astronaut to move around a spacecraft than on Earth. Fluids also rise toward a crew member’s head in microgravity creating pressure on the back of the eye potentially affecting vision. Doctors are constantly monitoring astronaut health to understand microgravity’s effect on the human body while living in space, develop countermeasures to treat space-caused issues, and promote long-term mission success as NASA and its international partners plan missions to the Moon, Mars, and beyond.

NASA flight engineer Jack Hathaway tested new workout methods on the European Enhanced Exploration Exercise Device (E4D) installed in the Columbus laboratory module. Hathaway first pedaled on the E4D’s exercise cycle then he reconfigured the device for resistance workouts including bicep curls, squats, bench press, and more. Afterward, he joined flight engineer Sophie Adenot of ESA (European Space Agency) and called down to researchers to discuss their experiences on the futuristic workout device optimized for exercising in space. Adenot also reviewed her support role for when she helps a pair of astronauts suit up ahead of the first spacewalk planned in August.

Adenot and Hathway then joined Roscosmos flight engineers Andrey Pyotr Dubrov and Fedyaev for eye checks in the Harmony module. Adenot led the first eye imaging round as Hathaway peered into a biomedical device that lets researchers on the ground examine his retina, lens, and cornea in real-time. Dubrov took charge of the second-round and guided Fedyaev as he took his optical exam.

Station commander Jessica Meir participated in an advanced eye exam while wearing a set of virtual reality goggles, also called the Nevada Screening Vision System. The head-mounted display system measures visual function using a series of vision screening apps testing visual acuity, contrast sensitivity, and more. Earlier, she took turns with NASA flight engineer Anil Menon and practicing their spacewalk procedures on a computer using 3D interactive animation software. The astronauts are scheduled to begin a spacewalk at 7:35 a.m. EDT on Thursday, Aug. 6. Menon also worked inside the Kibo laboratory module and cleaned its cooling fluid systems.

Dubrov partnered with Roscosmos flight engineer Anna Kikina and began their shift together testing the performance of life support hardware inside the Zarya module. Kikina then moved on and checked the data output of scientific hardware then tested the functionality of video recording gear. Fedyaev spent his shift in the orbital outpost’s Roscosmos segment working on orbital plumbing duties and Elektron oxygen generator maintenance.

NASA Awards 2026 Innovative Technology Concepts

NASA Awards 2026 Innovative Technology Concepts

The NASA Innovative Advanced Concepts (NIAC) program has created 18 new awards to support visionary ideas to improve aerospace technologies in areas ranging from the exploration of the solar system to understanding the universe.

The 18 NIAC Phase I awards total $3.2 million. Each award provides up to $175,000 for a nine-month initial investigation. The NIAC projects are about early-stage concept development and are not considered official NASA missions.

“NASA has outlined an ambitious vision for the future of space exploration, we’re returning the Moon to stay, advancing to Mars, and pushing to deepen our understanding of space,” said Greg Stover, director of the Advanced Research and Technology division within the Research and Technology Mission Directorate at NASA Headquarters in Washington. “Achieving that will require more than incremental technological advancement. It means we need great leaps. These awards are the kinds of innovation the world needs NASA to help foster.”

As an innovation incubator, NIAC funds early development of potential breakthrough technologies. Concepts for award consideration must have both transformative potential and possible feasibility for eventual implementation.

“Every innovation, every leap in technology, starts with a seed of an idea,” said Phillip Williams, NIAC’s acting program executive. “The NIAC program allows NASA to germinate those seeds and determine if there’s something that could be grown to benefit future space missions and our nation’s aerospace economy.”

As NASA and its partners push for sustained lunar presence, some of the 2026 awardees focused on ways to help explore the Moon and build infrastructure there. These include a system to support hovering robots to explore lava tubes under the Moon’s surface, a method to manage temperatures for small mobile exploration robots, and a way to incorporate radioisotopic heat sources into suits to help keep astronauts warm when operating in the Moon’s nearly two-week-long lunar nights.

Other concepts focus on exploring some of the solar system’s most remarkable features. Venus, with its hot atmosphere, presents an imposing challenge for research vehicles, so one NIAC awardee explores methods for hardening instruments for longer missions.

Two other concepts could help study planetary rings. One would use a swarm of 10,000 tiny satellites to map and analyze the rings of Saturn, while another would create a system for collecting samples from rings such as those circling Saturn, Uranus, and Neptune.

Some NIAC awardees will look far beyond the solar system, exploring ways to power interstellar spacecraft, map out continents on exoplanets, observe the photon rings around black holes, and detect subtle gravitational waves to explain how galaxies formed. Others will work to answer questions directly related to life on Earth, like the potential use of spaceborne dust to reduce solar radiation, and awareness about the debris orbiting Earth.

Researchers, known as NIAC Fellows, will investigate their concepts and identify potential challenges and opportunities for further development.

Description

NASA’s Curiosity Mars rover captured this sand-capped butte, nicknamed “Miraflores,” estimated to be about 20 feet (6 meters) tall, with its Mast Camera, or Mastcam, on June 11, 2026, the 4,923rd Martian day, or sol, of the mission. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley Curiosity is climbing through. 

The surrounding area includes an expanse of terrain covered in surface features called polygons.

The panorama is made up of 11 individual images that were sent to Earth and stitched together. The color has been adjusted to match lighting conditions as the human eye would see them on Earth.

Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio. Malin Space Science Systems in San Diego built and operates Mastcam.
