Ejection Mechanism Design for the SPEED Test Architecture Challenge

The The Stratospheric Projectile Entry Experiment on Dynamics (SPEED), a two-stage stratospheric drop test architecture, is currently under development to bridge the state-of-the-art gap that many NASA flagship missions require to reduce system risk and enable more optimized designs via margin reduction. To do this, a two-stage vehicle will drop from a high-altitude balloon and use the first stage (an LV-Haack cone aeroshell) to accelerate the sub-scale test model to supersonic conditions. The onboard avionics will then release the test model into freestream flow at the proper altitude in Earth’s atmosphere for dynamic Mach scaling to the full-scale flight trajectory. SPEED leverages low-cost methods of manufacturing such as 3D printing and laser/water-jet cutting to enable 8 or more two-stage vehicles to be dropped in a single test, making the science-to-dollar density much higher than any current ground-test facility NASA has at its disposal. The goal is to develop a robust ejection system that can reliably introduce the test models into supersonic flow with a tight variance on initial condition perturbation. The separation system must be capable of handling a range of initial angle-of-attacks, keep the test model secure in the first stage during take-off and descent, and eject the test model in such a way that it does not linger behind the first stage and be affected by the resulting wake. As current ejection system designs are conceptual, complex, and untested, NASA is looking for alternative ideas that can be incorporated into the design of their next iteration of SPEED flight vehicles to increase system reliability. We are challenging the public to design innovative concepts for a separation mechanism that can be used to assess NASA and commercial reentry vehicle stability.

NASA Funds Early Career Employee Research

Sylvie Crowell, a materials researcher at NASA’s Glenn Research Center in Cleveland, has received a NASA Early Career Initiative (ECI) award for a research proposal titled “Lunar Dust Reduction through Electrostatic Adhesion Mitigation (L-DREAM).” The research focuses on developing a passive lunar dust mitigation coating for solar cells and thermal control surfaces. 

Operated under the NASA Space Technology Mission Directorate, the award will fund Crowell’s research in fiscal year 2026, beginning Oct. 1, 2025.  

NASA’s ECI is a unique opportunity for the best and brightest of NASA’s early career researchers to lead hands-on technology development projects. The initiative aims to invigorate NASA’s technological base and best practices by partnering early career NASA leaders with external innovators.

Curiosity Blog, Sols 4597-4599: Wide Open Spaces

Written by Michelle Minitti, MAHLI Deputy Principal Investigator, Framework

Earth planning date: Friday, July 11, 2025

Imagine this vista as the view out your office window to start your workday. Your natural tendency would be to grab your camera and photograph as much of the view as possible. Curiosity was lucky enough to find herself in this situation today after a successful drive of about 61 meters (about 200 feet) on Wednesday, and the science team operating Curiosity wasted no time papering the scene with mosaics.
Between Mastcam and ChemCam, we planned 105 images across the scene. Those images will capture the structures underpinning the boxwork ridges we are driving toward, smaller-scale fractures in the near field that might be related to the boxwork ridges, and the back side of a ridge we recently studied in detail, “Volcán Peña Blanca.” Together, the images will help us understand the geologic history of the area that hosts the boxwork ridges, and what conditions existed in this part of Mount Sharp to support their formation.

We did not neglect the rocks directly in front of the rover as we gazed at our surroundings. Indeed, the bedrock near the rover was nearly uniformly packed with small (less than 1 centimeter, or 0.39 inches) rounded nodules, a characteristic we have not seen for awhile. MAHLI will image three different instances of the nodules while APXS and ChemCam will each analyze two different targets to understand the chemistry of the nodules and the bedrock hosting them.

REMS, RAD, and DAN will continue to monitor the Martian environment and subsurface throughout the weekend. Additionally, we planned multiple observations of dust devils, the amount of dust in the atmosphere, and clouds including a cloud movie timed to match the overflight of the CASSIS instrument. Our drive will take us to the foot of the smooth slope seen in the distance of the above image. That slope is the ramp we will take to the top of a big boxwork structure, where surely other delightful vistas await.

NASA Selects Companies for Architect-Engineer Services Contract

NASA has selected seven companies to assist the agency with architectural and engineering services at multiple agency centers and facilities.

The Western Regional Architect-Engineer Services is an indefinite-delivery/indefinite-quantity multiple award contract has a total estimated value not to exceed $75 million. The contract was awarded on July 14 with a five-year period of performance with the possibility of a six-month extension.

The selected contractors are:

• DYNOTEC-KZF JV LLC of Columbus, Ohio
• Merrick-IMEG JV LLP of Greenwood Village, Colorado
• G Squared Design of Lakewood, Colorado
• Kal Architects Inc. of Irvine, California
• AECOM Technical Services Inc. of Los Angeles
• Stell SIA Sala O’Brien LLC DBA S3, LLC (S3) of Mountlake Terrace, Washington
• Jacobs Engineering Group Inc. of Arlington, Virginia

Under the contract, the awarded companies will support general construction, alteration, modification, maintenance and repair, new construction of buildings, facilities, and real property for NASA’s Ames Research Center in California’s Silicon Valley and Armstrong Flight Research Center in Edwards, California. Support also includes optional back-up capacity in support of other NASA centers and federal tenants at agency facilities, including NASA’s Jet Propulsion Laboratory in Southern California, Goldstone Deep Space Communications Complex in Fort Irwin, California, and the NASA launch alliance at Vandenberg Space Force Base in California.
