Can Someone Give NASA a Hand with its Asteroid Canister?

Remember when you had to run the pickle jar under the faucet before you could take off the lid? Well, this can even happen to scientists. In fact, it has happened with NASA’s Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) sample canister.

NASA has reported that it is still trying to get the lid off of the canister, though it has been able to collect material from outside the container. On Friday, NASA stated:

In the last week, the team at NASA’s Johnson Space Center in Houston changed its approach to opening the TAGSAM head, which contained the bulk of the rocks and dust collected by the spacecraft in 2020. After multiple attempts at removal, the team discovered two of the 35 fasteners on the TAGSAM head could not be removed with the current tools approved for use in the OSIRIS-REx glovebox. The team has been working to develop and implement new approaches to extract the material inside the head, while continuing to keep the sample safe and pristine.

NASA stated it may take a few more weeks to resolve since the scientists need to be careful with the tools they use in the confined space.

The good news is that, even without the additional material, the team has already recovered about 70 grams of material from asteroid Bennu sample, which surpasses the agency’s goal of bringing at least 60 grams to Earth.

It is a pretty odd ending after the sample has gone through a multi-year journey before landing in the Utah desert. At least the sample canister is in a safe place while the scientists play with it.

Pic of the Week: Annular Solar Eclipse Over the U.S.

This image of last week’s annular solar eclipse was captured by NASA’s Earth Polychromatic Imaging Camera (EPIC) imager carried aboard the Deep Space Climate Observatory (DSCVR), which is a joint venture between NASA, NOAA, and the U.S. Air Force.

NASA made this statement regarding the image:

An annular eclipse occurs when the Moon passes in front of the Sun but is too far from Earth to completely obscure it. The Moon is at or near its farthest distance from Earth—known as its apogee—during an annular eclipse, making it look smaller in the sky. This leaves the Sun’s edges exposed in a red-orange ring, dubbed the “ring of fire.” A satellite caught an earthly view of the event, as the Moon’s shadow crossed North America.

NASA also provided a map showing those areas in the United States most impacted by the eclipse (shown below).

NASA has selected 72 student teams to begin an engineering design challenge to build human-powered rovers that will compete next April at the U.S. Space & Rocket Center in Huntsville, Alabama, near the agency’s Marshall Space Flight Center. Celebrating its 30th anniversary in 2024, the Human Exploration Rover Challenge tasks high school, college, and university students to design, build, and test lightweight, human-powered rovers on an obstacle course simulating lunar and Martian terrain, all while completing mission-focused science tasks.

NASA is mobilizing the scientific community to ensure the agency’s next big space telescope will be ready to deliver a “big picture” view of the universe almost immediately after launching. The Nancy Grace Roman Telescope — also known as the Roman Space Telescope, or just Roman — is set to launch in 2027 and will view the cosmos with a staggeringly wide field of view. Its big-picture observations of distant and early galaxies could help scientists solve the mysteries of dark matter and dark energy. Collectively, this so-called dark universe accounts for 95% of the energy and matter in the cosmos, yet the true nature of dark matter and dark energy eludes scientists.

New plans have been revealed for a $2 billion research center run by UC Berkeley at the NASA Ames Center in Mountain View, Santa Clara County. The Berkeley Space Center, as it will be called, will reshape 36 acres on the sprawling Ames Research Center, providing a hub for future companies to collaborate with the school and NASA scientists & engineers to improve technology for aviation, space exploration, and how people live and work in space.

Space Quote: Rich Bounty from the Asteroid Bennu Sample

“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.

Audit Results: More Concern About NASA’s Space Launch System

Posted on by onespaceman2000

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.

In its report, NASA’s Transition of the Space Launch System to a Commercial Services Contract, NASA OIG concludes:

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.
