NASA NASA pilot Joe Walker sits in the pilot’s platform of the Lunar Landing Research Vehicle (LLRV) number 1 on Oct. 30, 1964. The LLRV and its successor the Lunar Landing Training Vehicle (LLTV) provided the training tool to simulate the final 200 feet of the descent to the Moon’s surface.
The LLRVs, humorously referred to as flying bedsteads, were used by NASA’s Flight Research Center, now NASA’s Armstrong Flight Research Center in California, to study and analyze piloting techniques needed to fly and land the Apollo lunar module in the moon’s airless environment.

Image: The construction phase of ESA’s Ariel mission has started at Airbus Defence and Space in Toulouse (France) with the assembly of the spacecraft’s structural model. This marks a significant step forward for this mission designed to meticulously inspect the atmospheres of a thousand exoplanets and uncover their nature.
In the image we see Ariel’s structural model coming together at the Airbus facilities. This model replicates the mechanical framework of the spacecraft and the mass of its various units for a first round of tough testing.
The Ariel’s structural model consists of two main components: a flight-like replica of the service module (bottom right) and a simplified mechanical mock-up of the payload module (top right). This assembly mimics the structure of the flight spacecraft, where the science instruments make up the payload while the service module houses the essential components for the functioning of the spacecraft, such as the propulsion, and the power and communication systems.
The goal for the end of the year is to complete the mechanical test campaign of the spacecraft’s structural model. This will ensure that Ariel’s design is up-to-spec and can withstand the mechanical strains expected during launch.
The testing phase will include vibration and acoustic test campaigns. During vibration tests the model will be progressively shaken at different strengths on a vibrating table, or 'the shaker'. During acoustic tests, it will be placed in a reverberating chamber and ‘bombarded’ with very intense noise, like it will encounter during launch.
This model will also be used to assess how the loads are distributed and to perform a first ‘separation and shock’ test using the same mounting system as will be used to mount the spacecraft on the Ariane 6.
When ready, Ariel will be launched by an Ariane 6.2 rocket and journey to the second Lagrangian Point from where it will carry out its uniquely detailed studies of remote worlds.
Image description: A collage of three photographs that show the assembly of the model of a spacecraft in a large white hall. The first image on the left shows the entire model, with a person next to it who is nearly equal in height. The second image on the upper right zooms in on the top part of the mock science instrument: a circular fan-like structure with a big rectangular silver box on top. The third image on the lower right focuses on the bottom of the model, which looks like a large round silver box.

The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area.Skydweller Aero NASA’s Stennis Space Center near Bay St. Louis, Mississippi, has entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a key step towards achieving a strategic center goal.
The Reimbursable Space Act agreement marks the first between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems.
“There are few locations like NASA Stennis that offer a secure location, restricted airspace and the infrastructure to support testing and operation of various uncrewed systems,” said NASA Stennis Director John Bailey. “Range operations is a critical area of focus as we adapt to the changing aerospace and technology landscape to grow into the future.”
NASA Stennis and Skydweller Aero finalized the agreement in late August, paving the way for the company to begin area test flights of its autonomous, uncrewed solar-powered aircraft, which features a wingspan greater than a 747 jetliner and is designed for long-duration flights. The company announced Oct. 1 it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours.
NASA Stennis and Skydweller Aero began talks in the summer of 2023 when the company expressed interest in utilizing NASA Stennis airspace for its all-carbon fiber aircraft. The NASA Stennis area fits the company’s needs well since it provides ready access from Stennis International Airport to the Gulf of Mexico area. NASA Stennis airspace also provides a level of privacy for aircraft testing and operation.
“Access to the restricted airspace above NASA Stennis has been tremendously helpful to our uncrewed, autonomous flight operations,” said Barry Matsumori, president and chief operating officer of Skydweller Aero. “The opportunity to use the controlled environment above Stennis helps accelerate our efforts, allowing us to transition the aircraft in and out of civil airspace, while demonstrating its reliability and unblemished safety record to the FAA.”
Companies must be conducting public aircraft operations to use any restricted airspace. In this instance, Skydweller Aero is flying its aircraft in association with the U.S. Department of Defense, allowing for the Reimbursable Space Act agreement with NASA Stennis.
The agreement provides the company Federal Aviation Administration (FAA) authorization for future test flights in designated areas of the NASA Stennis buffer zone. It also represents a key step in the center’s effort to grow its range operations presence.
“This really opens the door for others to come here,” said Jason Peterson, NASA Stennis range officer. “There are requirements that must be met, but for those who meet them, NASA Stennis is an ideal location for test and flight operations.”
The FAA established restricted airspace at NASA Stennis in 1966 and approved its expansion in 2016. The expansion was necessary to conduct propulsion testing safely, accommodate U.S. Department of Defense missions, and support unmanned aerial systems activities.
Restricted airspace at NASA Stennis allows qualifying organizations to conduct various uncrewed flight activities. NASA Stennis personnel provide scheduling and range operation support, including reviews and evaluations to ensure safe flight operations. Processes are in place to ensure communication between aircraft operators, FAA air traffic controllers, and range safety personnel.
Peterson said he hopes the agreement with Skydweller Aero will clear the way for future collaborations as NASA Stennis continues to expand its customer-based operations. For instance, although Skydweller Aero is not located onsite, NASA Stennis is able to support ground operations for a variety of unmanned aircraft system takeoffs and landings.
Beyond that, the center also hopes to expand its operational capabilities to include marine and ground activities. In addition to a large geographic footprint, the center features a secure 7.5-mile waterway canal system for testing unmanned underwater or surface vehicles.

The day began with an 85% chance that bad weather would cause a launch delay: it ended with ESA’s Hera mission successfully in space and en route to the Didymos binary asteroid system.
At 16:52 CEST (14:52 UTC) on 7 October 2024, Hera took to the skies aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, USA. After a smooth 76-minute ascent, the spacecraft separated from its launcher, and, a few minutes later, ESA’s ESOC mission operations centre in Germany assumed control of the spacecraft.
Here is what has happened since then.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The HASP 1.0 (High-Altitude Student Platform) scientific balloon mission launched Sept. 4, 2024, during NASA’s fall balloon campaign in Fort Sumner, N.M.NASA/Erin Reed NASA’s Scientific Balloon Program’s fifth balloon mission of the 2024 fall campaign took flight Wednesday, Sept. 4, 2024, from the agency’s Columbia Scientific Balloon Facility in Fort Sumner, New Mexico. The HASP 1.0 (High-Altitude Student Platform) mission remained in flight over 11 hours before it safely touched down. Recovery is underway.
HASP is a partnership among the Louisiana Space Grant Consortium, the Astrophysics Division of NASA’s Science Mission Directorate, and the agency’s Balloon Program Office and Columbia Scientific Balloon Facility. The HASP platform supports up to 12 student-built payloads and is designed to flight test compact satellites, prototypes, and other small experiments. Since 2006, HASP has engaged more than 1,600 undergraduate and graduate students involved in the missions.
Teams participating in the 2024 HASP 1.0 flight included: University of North Florida and University of North Dakota; Arizona State University; Louisiana State University; University of Colorado Boulder; College of the Canyons; Fort Lewis College; Capitol Technical College; University of Arizona; Universidad Nacional de Ingeniería (Peru); and McMaster University (Canada).
A new, larger version of the High-Altitude Student Platform (HASP 2.0) had its engineering test flight a few days prior. HASP 2.0 will be able to accommodate twice as many student experiments as HASP 1.0 once operational in the next year.
The remaining three balloon flights scheduled for the 2024 Fort Sumner fall campaign await next launch opportunities. To follow the missions, visit NASA’s Columbia Scientific Balloon Facility website for real-time updates on balloons altitudes and GPS locations during flight.
