“As we peer into the ancient secrets preserved within the dust and rocks of asteroid Bennu, we are unlocking a time capsule that offers us profound insights into the origins of our solar system…The bounty of carbon-rich material and the abundant presence of water-bearing clay minerals are just the tip of the cosmic iceberg. These discoveries, made possible through years of dedicated collaboration and cutting-edge science, propel us on a journey to understand not only our celestial neighborhood but also the potential for life’s beginnings. With each revelation from Bennu, we draw closer to unraveling the mysteries of our cosmic heritage.”
–Statement by Dante Lauretta, OSIRIS-REx principal investigator, regarding the recently-arrived sample collected from asteroid Bennu. NASA and its partners are expected to study the sample for the next two years to learn more about the asteroid and our solar system.
First, the US Government Accountability Office reported that NASA’s Space Launch System (SLS) is unaffordable, and now NASA’s Office of Inspector General (OIG) doubles down on that earlier finding, reporting that the SLS, a key component of the Artemis program, has costs that are spinning out of control.
Our analysis shows a single SLS Block 1B will cost at least $2.5 billion to produce—not including Systems Engineering and Integration costs—and NASA’s aspirational goal to achieve a cost savings of 50 percent is highly unrealistic. Specifically, our review determined that cost saving initiatives in several SLS production contracts such as reducing workforce within Boeing’s Stages contract and gaining manufacturing efficiencies with Aerojet Rocketdyne’s RS-25 Restart and Production Contract were not significant and, as a result, a single SLS will cost more than $2 billion through the first 10 SLS rockets produced under [the Exploration Production and Operations Contract].
NASA OIG concludes that maybe other contractors needs to be considered, stating:
Although Congress directed NASA in 2010 to build a heavy-lift rocket and crew capsule using existing contracts from the canceled Constellation effort to meet its space exploration goals, the Agency may soon have more affordable commercial options to carry humans to the Moon and beyond. In our judgment, the Agency should continue to monitor the commercial development of heavy-lift space flight systems and begin discussions of whether it makes financial and strategic sense to consider these options as part of the Agency’s longer-term plans to support its ambitious space exploration goals.
Where are these “more affordable commercial options”? Could it be SpaceX? Blue Origin? If so, let’s start the transition ASAP so that the Moon and Mars remain a realistic goal in the near future. We have plenty of talent in this country and a race to the top is what we need, not a space agency stuck with an Edsel rocket system.
It may be Friday the 13th, but the news has been positive about the Psyche spacecraft, which earlier today successfully launched from NASA’s Kennedy Space Center in Florida.
Here is part of a statement by Arizona State University Professor Lindy Elkins-Tanton, the Principal Investigator (PI) of the Psyche mission, from back in 2017 as she awaited word on whether the Psyche mission had been green-lighted by NASA:
I’ve only been working on this project for five and a half years. Some of my competitors have been through the process before with the same ideas, and are coming up on a decade of trying to fly their concept. Still, five and a half years. About 150 people have worked on this concept with me. We’ve written about 2,000 pages, including the step 1 and step 2 proposals and all the written, edited, revised, formatted, and published answers to questions that came in between. We have art and models and videos and new scientific and engineering results because of all our efforts to understand how to get to the metal world Psyche and what we might find if we did, and how we could measure it and send the information back to Earth and understand it and interpret it for everyone in the world.
To say our hearts are in this project would be too facile, too surficial, too trite. We have lived and breathed this. We know and love each other and we know each other’s families and we have learned when to be quiet and let the other person work through a peak of frustration late at night after no rest for weeks. We have sweated through countless reviews and celebrated with numerous cakes and dinners the many intermediate successes that allowed us to get here, the ultimate intermediate success, the privilege to wait for the phone call.
Here is PI Lindy Elkins-Tanton’s quote from earlier today:
We said ‘goodbye’ to our spacecraft, the center of so many work lives for so many years – thousands of people and a decade…But it’s really not a finish line; it’s a starting line for the next marathon. Our spacecraft is off to meet our asteroid, and we’ll fill another gap in our knowledge – and color in another kind of world in our solar system.
Congratulations to PI Lindy Elkins-Tanton and her team on a job well done (so far, of course).

This week’s image comes from the Jame Webb Space Telescope’s (JWST) Near-Infrared Camera (NIRCam). It shows the Ring Nebula, which is approximately 2,500 light-years away. It looks like a heavenly eyeball. with an Earth-colored iris.
Here is more on the image from NASA:
The NASA/ESA/CSA James Webb Space Telescope has observed the well-known Ring Nebula with unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring Nebula is an archetypal planetary nebula. Also known as M57 and NGC 6720, it is both relatively close to Earth at roughly 2,500 light-years away. This new image provides unprecedented spatial resolution and spectral sensitivity. For example, the intricate details of the filament structure of the inner ring are particularly visible in this dataset. There are some 20,000 dense globules in the nebula, which are rich in molecular hydrogen. In contrast, the inner region shows very hot gas. The main shell contains a thin ring of enhanced emission fromcarbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). Roughly ten concentric arcs are located just beyond the outer edge of the main ring. The arcs are thought to originate from the interaction of the central star with a low-mass companion orbiting at a distance comparable to that between the Earth and the dwarf planet Pluto. In this way, nebulae like the Ring Nebula reveal a kind of astronomical archaeology, as astronomers study the nebula to learn about the star that created it.

After a number of delays, the Psyche mission appears ready to go as the spacecraft sits at Launch Complex 39A at the Kennedy Space Center in Florida. The launch is scheduled for tomorrow at 10:16 a.m. EDT.
The spacecraft will not reach the metal-rich asteroid Psyche until 2029. It will then orbit the asteroid for about two years collecting data to learn more about an object that astronomers believe may contain clues about the formation of the rocky planets closest to the Sun.
