Steps taken by NASA, the agency’s Jet Propulsion Laboratory (JPL) in Southern California, and Caltech, to put the Psyche mission on track for an October 2023 launch have been outstanding, according to an independently appointed review board. NASA and JPL convened the board last summer after the Psyche mission team requested to delay the spacecraft’s August 2022 launch to a metal-rich asteroid of the same name.

In its November 2022 report, the independent review board made extensive recommendations to address both project and JPL institutional issues that contributed to the launch delay. After thorough follow-up reviews with the Psyche project, JPL, and Caltech, the board’s May 30 report finds the actions taken since November exceeded expectations. Caltech manages JPL for NASA.

“I am pleased with the independent review board’s resoundingly positive assessment of JPL’s hard work in correcting the issues outlined in the board’s original report,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate in Washington. “We know the work is not over. As we move forward, we will work with JPL to ensure these implemented changes continue to be prioritized to position Psyche and the other missions in JPL’s portfolio for success.”

Led by retired aerospace executive A. Thomas Young, the Psyche independent review board concluded in its initial report that while JPL workforce issues related to the COVID-19 pandemic contributed to the launch delay, additional factors, ranging from staffing to communication to management oversight, contributed as well.

In response to the review board’s recommendations, JPL moved to directly address the concerns regarding the Psyche project as well as the laboratory as an institution. The Psyche mission added experienced team members, reorganized a large part of its workforce, and adopted comprehensive metrics to monitor progress toward launch and operational readiness. The report also noted improvements to senior management’s oversight of the mission.

“The independent review board is extraordinarily impressed by the accomplishments of the total JPL organization and Caltech,” the report authors noted. “Engagement in and leadership of the overall response process by the JPL director and senior leadership is deemed ‘world class.'”

Institutionally, JPL moved rapidly to update its hybrid work policy to increase the number of days team members spend together onsite each week to improve collaboration and communication. The laboratory, according to the report, was also “exceptional” in its efforts to attract and retain experienced engineering staff, with the Psyche mission being among the beneficiaries.

In addition, JPL leadership focused on clarifying roles, responsibilities, and technical skillsets within its engineering organization while ensuring flight project team members were aware of pathways to raise concerns. Lessons learned from the Psyche mission also are applicable to other flight projects, including Europa Clipper and Mars Sample Return. JPL also revamped monthly project status reviews to ensure risks are well understood at all levels of the organization.

“We convened this board weeks after I stepped in as director and addressing the issues it raised has been a central focus in my first year as director of JPL. The results are gratifying,” said JPL Director Laurie Leshin. “Our goals went beyond getting Psyche to the launch pad to improving JPL across the board as we work on missions that will help us better understand Earth, explore the solar system and the universe, and search for signs of life. Our strong response to the board’s findings reinforces the notion that JPL can solve any problem with the right focus and attention.”

The board also determined in its report NASA and its management centers need to more clearly define the responsibilities of its standing review boards, which help ensure appropriate program and project management oversight to increase the likelihood of mission success.

The spacecraft will reach asteroid Psyche in August 2029, orbiting it for 26 months to gain insights into planetary formation, better understand the interior of terrestrial planets like Earth, and examine a world that is made largely of metal.

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.
