Following a successful launch of NASA’s SpaceX 28th commercial resupply services mission, two new solar arrays, science investigations, and supplies are on their way to the International Space Station.

Carrying more than 7,000 pounds of cargo to the orbiting laboratory, the uncrewed SpaceX Dragon spacecraft launched on the company’s Falcon 9 rocket at 11:47 a.m. EDT, Monday, June 5, from NASA’s Kennedy Space Center in Florida.

Live coverage of arrival will begin at 4:15 a.m., Tuesday, June 6, on NASA Television, the agency’s website, and the NASA app.

The cargo spacecraft is scheduled to autonomously dock with the space-facing port on the station’s Harmony module at approximately 5:50 a.m. and remain at the station for about 21 days.

The SpaceX Dragon will deliver a pair of IROSAs (International Space Station Roll Out Solar Arrays) that, once installed, will expand the energy-production capabilities of the microgravity complex.

The spacecraft will also deliver the following:

Thunderstorm Watch

What Happens Above Thunderstorms (Thor-Davis), an investigation from ESA (European Space Agency), will observe thunderstorms from the space station. This vantage point will allow researchers to see the electrical activity from above, particularly the inception, frequency, and altitude of recently discovered blue discharges. Scientists plan to estimate the energy of these phenomena to determine their effect on the atmosphere. A better understanding of lightning and electrical activity in Earth’s atmosphere could improve atmospheric models and provide a better understanding of Earth’s climate and weather.

Helping Plants Chill in Space

Plants exposed to environmental stress, including spaceflight, undergo changes to adapt, but those changes may not be passed on to the next generation. Plant Habitat-03 (PH-03) will assess whether plants grown in space can transfer such adaptations to the next generation and, if so, whether a change continues through subsequent generations or stabilizes.

The investigation will create a second generation of plants using seeds previously produced in space and returned to Earth. Results could provide insight into how to grow multiple generations of plants to provide food and other services on future space missions. This investigation also could support development of strategies for adapting crops and other economically important plants to marginal and reclaimed habitats on Earth.

Testing a Telomere Technique

Telomeres, genetic structures that protect our chromosomes, shorten with age and wear. But research has shown that telomeres lengthen in space. Genes in Spac e-10 will test a technique for measuring telomere length in microgravity, where methods typically employed on Earth are difficult to use due to gravity. The experiment will explore whether telomere lengthening in space is caused by proliferation of stem cells –undifferentiated cells that give rise to specific body components and that typically have long telomeres.

Understanding the mechanism behind telomere lengthening could reveal possible effects on astronaut health during long-duration missions. Results also could lay the groundwork for a variety of related research to benefit future space travel and people on the ground.

Genes in Space is a national contest for students in grades seven through 12 to design biotechnology experiments for space. The program is sponsored by miniPCR, Math for America, Boeing, New England Biolabs Ltd., and the International Space Station National Laboratory.

Thawing Ice, Solar Storms, and Attitude Recovery

Mission 26 for the station’s Nanoracks CubeSat Deployer (NRCSD) includes Educational Space Science and Engineering CubeSat Experiment Mission (ESSENCE), sponsored by the International Space Station National Laboratory and developed by universities in Canada and Australia. It carries a wide-angle camera to monitor thawing of ice and permafrost in the Canadian Arctic, which could provide a better understanding of the effects on Earth’s climate and support better local infrastructure planning.

The satellite also carries a solar energetic proton detector to collect data on periods of solar activity that emit highly energized radioactive protons that can damage the structure and electronic components of spacecraft. Understanding these effects could help make future CubeSats more resistant to radiation. In addition, the investigation demonstrates a novel method to recover control of a satellite’s attitude, or orientation, if a control mechanism fails. ESSENCE is part of the Canadian CubeSat Project, led by CSA (Canadian Space Agency).

Watching Cosmic Weathering

Iris, sponsored by the International Space Station National Laboratory, observes weathering of geological samples exposed to direct solar and background cosmic radiation and determines whether changes are visually detectable. The investigation also demonstrates experimental sun sensors, torque rods (which provide attitude control and detumbling for satellites), and a battery heater. A collaboration between graduate, undergraduate, and middle school students in Canada, the project provides hands-on experience that promotes interest in science, technology, engineering, and mathematics studies and careers.

Results also could provide insight into weathering processes on planetary bodies and, when combined with data from asteroid sampling missions, improve understanding of the origins of asteroids. Iris is part of the Canadian CubeSat Project, led by CSA.

Celebrating National Panda Day: Conservation of Precious Bears

March 16 is National Panda Day – a celebration of these fluffy, bamboo-munching bears and a reminder to protect their environment. #PandaDay

Published

on


Every year on March 16th, we come together to celebrate National Panda Day, a delightful occasion dedicated to honoring China’s beloved bamboo-munching bears. As a source of national pride, pandas hold a special place in our hearts. With two subspecies, including the iconic Giant Panda and the smaller Qinling Panda, these magnificent creatures play an essential role in China’s unique ecosystem. While their population status has improved from endangered to vulnerable, we must remain committed to preserving pandas and their habitat. In this blog post, we will explore the significance of pandas, their conservation efforts, and the importance of safeguarding their environment.

The Significance of Pandas and their Habitat:
Pandas, particularly the Giant Panda, are revered for their fluffy black and white coats and captivating presence. These awe-inspiring animals are exclusive to the remote, mountainous regions of China. The Qinling Panda, a smaller brown subspecies, was discovered in the mountain ranges of southern Shaanxi Province in China in 1985. However, both subspecies have a crucial role to play in their respective ecosystems. Giant pandas, in particular, thrive on bamboo forests, spreading seeds as they roam and promoting the growth of new vegetation. This symbiotic relationship nurtures not only pandas but also benefits other wildlife and humans.

Endangered Status and Conservation Efforts:
While the panda population has shown some promising growth, there are still fewer than 2,000 pandas left in the wild due to various threats. Habitat loss, farming activities, fur hunting, and other factors have jeopardized their existence. To combat this, conservation organizations, including 27 zoos around the world, are actively working towards protecting giant pandas and creating environments conducive to reproduction. However, the most critical aspect of preserving pandas is the conservation of their natural environment, especially bamboo forests, which serve as their primary source of nutrition.

The History and Importance of National Panda Day:
The exact origin of National Panda Day remains unclear, but it is undoubtedly a day dedicated to spreading awareness and appreciating the beauty and significance of pandas. In 1961, the creation of the World Wide Fund for Nature (WWF) solidified the panda’s global conservation symbol. The panda’s inclusion in the WWF logo was quite fitting, as this animal represents both beauty and endangerment, garnering love from people worldwide. It has become an emblem for the conservation movement, calling upon individuals and nations to protect endangered species and preserve natural wildlife habitats.

Preserving Pandas and Their Ecosystem:
While pandas are now classified as vulnerable, the battle to protect them is far from over. The efforts of zoos, reforestation initiatives, and conservation campaigns have contributed to the positive change in their status. However, it is crucial to continue protecting their environment. Preservation of the giant panda’s natural habitat not only safeguards the bears themselves but also supports the survival of 70% of the country’s forest birds, 70% of mammals, and 31% of amphibians, according to a scientific paper published by The Society for Conservation Biology in 2015. Pandas are essential for forest health, and it is our collective responsibility to ensure their well-being.


National Panda Day serves as a reminder of the remarkable role pandas play in our natural world. While progress has been made, the conservation journey is ongoing. We must remain steadfast in protecting pandas and their environment to secure their long-term survival. By raising awareness, supporting conservation efforts, and advocating for the preservation of bamboo forests, we can create a future where these adorable, bamboo-munching bears continue to thrive and contribute to the vibrant ecosystems of China and the world. Let’s celebrate National Panda Day and join hands in safeguarding these precious creatures for generations to come.

Unveiling the Mysteries of Comet 12P/Pons Brooks: The Devil Comet’s Rare Celestial Show

Explore the enigmatic beauty of Comet 12P/Pons Brooks, the “Devil Comet,” as it graces our skies with rare eruptions and celestial displays.

Published

on

Comet 12P/Pons Brooks, known as the “devil comet,” is an intriguing celestial visitor that has captured the attention of astronomers and stargazers alike. This comet, with a diameter of about 10.5 miles (17 kilometers), follows a highly elliptical orbit around the sun, completing its journey approximately every 71 years. What sets 12P apart is its cryovolcanic nature – an ice volcano in space.

The icy shell of 12P occasionally erupts due to solar radiation, releasing a mix of ice and gas known as cryomagma into space. This process significantly expands the comet’s coma, the cloud of gas and dust surrounding its nucleus, making it appear brighter for a few days. In July 2023, astronomers witnessed 12P erupt after nearly 70 years, with subsequent eruptions occurring more frequently.

During earlier eruptions, the comet’s expanded coma gave it a unique appearance resembling demonic horns. However, recent observations show that these horns seem to have vanished, replaced by a distinctive green glow caused by high levels of dicarbon in its coma and tail, a rare phenomenon in comets.

For sky watchers in the Northern Hemisphere, viewing opportunities are optimal before April 21, when 12P makes its closest approach to the sun. Post this date, the comet will become visible to those in the Southern Hemisphere until the year’s end. To catch a glimpse, head to the countryside away from city lights. While visible to the naked eye, binoculars can enhance the viewing experience.


12P has surprised observers with unexpected brightness, including a rare flare that transformed its gas cloud into a horseshoe shape, earning it monikers like the Devil Comet or Millennium Falcon Comet. Additional flares have been detected, hinting at potential future surprises as the comet approaches Earth.

The cause of these flare-ups remains a mystery, with some astronomers speculating about rare volcanic activity on the comet’s surface. When planning a stargazing outing, target days closest to a new moon to avoid moonlight interference. Checking the weather forecast is essential to ensure clear skies for optimal viewing conditions.

Upon arrival at your stargazing spot, allow your eyes time to adjust to the darkness, especially if you’ve been exposed to bright screens. Patience is key, as celestial wonders like Comet 12P/Pons Brooks often reveal themselves gradually, rewarding those willing to wait.

As you gaze at this unique cosmic spectacle, reflect on the transient nature of comets and the vast mysteries of the universe they represent. The journey of Comet 12P serves as a poignant reminder of the beauty and unpredictability of celestial phenomena, inviting us to marvel at the wonders of the cosmos and contemplate our place within it.
