A Striped Surprise

Last week, team scientists and the internet alike were amazed when Perseverance spotted a black-and-white striped rock unlike any seen on Mars before. Is this a sign of exciting discoveries to come?

It has now nearly been a month since the rover began its climb up the steep slopes leading to the crater rim, on the hunt for ancient rocks that could teach us about early Martian history. While these tricky slopes made for a slow initial ascent, drive progress has improved greatly in recent days, as Perseverance has cruised along a flatter stretch. From this overlook, the rover can now spot landmarks from earlier in the mission like the iconic ‘Kodiak’ butte on the hazy horizon, thick with dust from nearby dust storms.

While driving across unremarkable pebbly terrain, beady-eyed team members spotted a cobble in the distance with hints of an unusual texture in low resolution Navcam images, and gave it the name ‘Freya Castle’. The team planned a multispectral observation using the Mastcam-Z camera in order to get a closer look before driving away. When these data were downlinked a couple days later, after Perseverance had already left the area, it became clear just how unusual it was! ‘Freya Castle’ is around 20 cm across, and has a striking pattern with alternating black and white stripes. The internet immediately lit up with speculation about what this “zebra rock” might be, and we’ve enjoyed reading your theories!

The science team thinks that this rock has a texture unlike any seen in Jezero Crater before, and perhaps all of Mars. Our knowledge of its chemical composition is limited, but early interpretations are that igneous and/or metamorphic processes could have created its stripes. Since Freya Castle is a loose stone that is clearly different from the underlying bedrock, it has likely arrived here from someplace else, perhaps having rolled downhill from a source higher up. This possibility has us excited, and we hope that as we continue to drive uphill, Perseverance will encounter an outcrop of this new rock type so that more detailed measurements can be acquired.

‘Freya Castle’ is merely the latest in a series of intriguing rocks found recently; ever since arriving in the vicinity of the crater rim, the team has noticed an increased variety of rocks, such as the diverse collection of boulders at ‘Mount Washburn’. Could these be our first glimpses at ancient rocks uplifted from depth by the Jezero impact, now exposed on the crater rim? Only time will tell…

NASA Expands Small Business, Industry Engagement Resources

Two new resources are available for businesses that provide products and services to support NASA’s missions, from supersonic flight to lunar exploration, as well as companies that aim to engage the agency as a customer.

While NASA practices transparency in its procurement processes to ensure access and participation by all businesses, we recognize that barriers to participation remain for smaller, less experienced companies. In addition, new federal-wide policy and guidance has increased focus on NASA’s small and minority business goals.

“NASA’s dedication to fostering collaboration with small and disadvantaged businesses remains at the forefront of our mission,” said NASA Deputy Administrator Pam Melroy. “By implementing innovative practices and refining our procurement processes, we aim to not only drive forward our key mission objectives but also to stimulate industry-wide innovation and inclusivity. These efforts are vital as we seek to leverage the full spectrum of talent and creativity available, ensuring that all voices have a chance to contribute to our groundbreaking work in space exploration.” 

To assess the agency’s best practices and biggest barriers, Deputy Administrator Melroy established a multi-disciplinary team that included the Offices of Procurement and Small Business Programs. One of the outcomes was the creation of a communication plan for the small and minority business enterprise alongside NASA’s annual vendor communication plan.

“Inherent in NASA’s commitment to innovation and ingenuity, is the recognition that a diverse and broad supply chain is essential for mission success,” said Karla Smith Jackson, assistant administrator for NASA’s Office of Procurement. “The updated Vendor Communication and the new Small and Minority Business Enterprise Communication plans are the next logical step in NASA’s continuous effort to foster an inclusive acquisition environment. By broadening our communication and outreach, we are strengthening our industrial base and empowering businesses of all sizes to contribute to the future of space exploration.”

In the NASA Small and Minority Business Enterprise Communication Plan, the agency outlines its goals for enhancing its outreach efforts and increasing spending with these businesses to reduce obstacles to participation in NASA’s missions and more intentionally engage companies throughout the procurement process.

Engagement activities outlined in these plans support more robust communication with potential vendors. As an example, the NASA Acquisition Innovation Launchpad (NAIL) encourages one-on-one conversations with small and minority-owned businesses to improve participation, drive innovation, identify and remove barriers as well as collaboration to share best practices and methods across the agency. Further, by publishing annual forecasts we give industry insight as early as possible to promote maximum competition.

“Our commitment to small and minority businesses is unwavering,” said Dwight Deneal, assistant administrator for NASA’s Office of Small Business Programs. “This communication plan is not just about outreach; it’s about building lasting partnerships that drive innovation and inclusion across NASA’s missions.”

The Vendor Communication Plan goes into more depth on how NASA engages with all businesses before, during, and after contract awards are given, providing various examples of events and methods of communication the agency uses to remain in contact with award recipients. This includes holding webinars with award applicants and recipients, providing email support throughout the award process, and reviewing final performance and financial reports. NASA also provides information about how the agency promotes diversity throughout the contracting process, including a dedicated equity action plan and increased subcontracting opportunities.

In the spirit of exploration, NASA is expanding its reach to new entrants and businesses that have not traditionally done business with the agency. NASA is committed to increasing its small business prime and subcontract awards, with an emphasis on innovative barrier reducing procurement practices and transparent contracting methods.

Find Exoasteroids and Peek into the Future

What will remain of our solar system a few billion years from now?  We’re launching the Exoasteroids project to gather some clues. Join this new citizen science project, and help search for variable white dwarfs – bizarre objects that we can catch in the act of disassembling planetary systems.

White dwarfs each pack the mass of a star into a ball the size of a planet. They are also the future of our solar system.  A few billion years from now, the Sun will evolve into a red giant and then into a white dwarf, devouring the innermost planets and millions of asteroids in the process.

With the Exoasteroids project, you’ll search for white dwarfs that are growing brighter or dimmer.  Such white dwarfs may be remnants of planetary systems still actively munching on asteroids, leading to outbursts detectable in images from NASA’s Wide-field Infrared Survey Explorer (WISE) space telescope.

Help us find planetary remains and disintegrating asteroids in other solar systems!

Anyone with a laptop or cell phone can participate. Participation does not require citizenship in any particular country.

NASA Astronaut Tracy C. Dyson, Crewmates Return from Space Station

NASA astronaut Tracy C. Dyson completed a six-month research mission aboard the International Space Station on Monday, returning to Earth with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub.

The trio departed the space station aboard the Soyuz MS-25 spacecraft at 4:36 a.m. EDT Monday, Sept. 23, making a safe, parachute-assisted landing at 7:59 a.m. (4:59 p.m. Kazakhstan time), southeast of the remote town of Dzhezkazgan, Kazakhstan.

While aboard the orbiting laboratory, Dyson conducted multiple scientific and technology activities including the operation of a 3D bioprinter to print cardiac tissue samples, which could advance technology for creating replacement organs and tissues for transplants on Earth. Dyson also participated in the crystallization of model proteins to evaluate the performance of hardware that could be used for pharmaceutical production and ran a program that used student-designed software to control the station’s free-flying robots, inspiring the next generation of innovators.

Dyson launched on March 23 and arrived at the station March 25 alongside Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.

Spanning 184 days in space, Dyson’s third spaceflight covered 2,944 orbits of the Earth and a journey of 78 million miles as an Expedition 70/71 flight engineer. Dyson also conducted one spacewalk of 31 minutes, bringing her career total to 23 hours, 20 minutes on four spacewalks.

Kononenko and Chub, who launched with O’Hara to the station on the Soyuz MS-24 spacecraft last September, spent 374 days in space on a trip of 158.6 million miles, spanning 5,984 orbits. Kononenko completed his fifth flight into space, accruing a record of 1,111 days in orbit, and Chub completed his first spaceflight.

Following post-landing medical checks, the crew will return to the recovery staging city in Karaganda, Kazakhstan. Dyson will then board a NASA plane bound for the agency’s Johnson Space Center in Houston.
