The NASA Overview: Artemis III Stacking Advances as Chandra Finds 84 Objects

Artemis III Stacking Continues as Crew Signs Hardware

Artemis III stacking continues at Kennedy Space Center as technicians assemble the twin solid rocket boosters that will provide more than 75% of the rocket’s total thrust at launch. The mission, scheduled for 2027, will send a new crew into low Earth orbit aboard Orion. Four RS-25 rocket engines are now on the work stand for integration with the core stage, generating more than two million pounds of thrust at liftoff.

The Artemis III crew recently signed their names on the hardware that will be inside their Orion spacecraft during the mission. Meanwhile, the Artemis II crew — NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman, and CSA (Canadian Space Agency) astronaut Jeremy Hansen — visited NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Sept. 1, 2026. The event gave the crew an opportunity to share firsthand experiences from their mission and connect with the workforce that supported the flight through a question-and-answer session.

Following their landmark Artemis II mission earlier this year, Glover and Wiseman are transitioning to emeritus status at NASA’s Johnson Space Center in Houston. In the emeritus role, they will continue to support the agency by donating their time to train and mentor the current workforce. Administrator Jared Isaacman noted that Glover will transfer his knowledge of Orion and its spacecraft systems to future Artemis missions.

NextSTEP-3 Solicitation Targets Lunar Surface Technologies

NASA announced on Sept. 8 a new solicitation targeting capability gaps for lunar exploration and a Moon Base in the lunar South Pole region. The NextSTEP-3 Broad Agency Announcement Appendix A: Lunar Enabling Infrastructure Accelerator seeks proposals in five areas:

  • Vertical solar array technology for consistent power generation, management, distribution, and energy storage
  • In-situ resource utilisation oxygen from regolith production to extract usable oxygen molecularly bonded to rock and dust
  • Radioisotope Stirling generator, a type of nuclear energy technology using heat from fissile materials to produce electric power
  • In-space advanced manufacturing to reduce reliance on resupply missions from Earth
  • Innovative nanomaterials production for lunar exploration

“NASA is accelerating the development of key technologies and closing critical gaps needed for long-term human exploration at the Moon,” said Greg Stover, director of NASA’s Advanced Research and Technology Division. “Partnering with industry will strengthen the U.S. industrial base as we mature the capabilities and infrastructure needed for a sustainable lunar presence.”

Chandra Uncovers 84 Mysterious X-Ray Objects

Using NASA’s Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike anything previously observed. Researchers found 84 so-called hypersoft X-ray sources in M101, Messier 31, and four elliptical galaxies. These objects give off unusually low-energy X-rays but intense levels of ultraviolet radiation.

“We’ve never encountered a group of objects that act like this,” said Mustafa Muhibullah of the University of Alabama, who led the study. The discovery is featured in a paper published Wednesday in Nature Astronomy. The objects’ existence may help explain questions around Type Ia supernova explosions and the intergalactic medium.

In other deep space news, NASA’s Roman Space Telescope launched on Aug. 30 and is on its way to its final destination, where it will change how we view the universe. First images from Roman are expected by early 2027. Hubble also captured a superbubble in the Large Magellanic Cloud spanning over 200 light-years across, helping astronomers study how stars are born.

Expedition 75 Science and a Cargo Departure

Expedition 75 kept a busy research schedule this week. Crew members worked with a new microscope, crystal growth hardware, and spacesuits while also conducting vein scans, ultra-hot physics experiments, and Earth observations.

Last week, ESA astronaut Sophie stepped outside the station to swab for microbes near life support systems. Samples could reveal how microbes may spread from a spacecraft and help scientists limit contamination on future missions to the Moon and beyond.

A trash-packed Progress 94 cargo spacecraft departed the orbital outpost on Monday, Sept. 7, and reentered Earth’s atmosphere above the South Pacific Ocean for a fiery but safe demise. Four spaceships remain parked at the station.

Relativity Space Joins NLS II, NFL Partnership Announced

NASA has awarded a Launch Services (NLS) II contract to Relativity Space Inc. for its Terran R launch service under the contract’s on-ramp provision. The NLS II contracts are multiple-award, indefinite-delivery/indefinite-quantity contracts with an ordering period through June 2030 and an overall period of performance through December 2032. The Terran R launch service will be available for future NASA missions.

In outreach news, NASA is teaming up with the NFL to bring the excitement of America’s space program directly to fans. The Inspiration Tour will visit four games this fall, featuring NASA aircraft flyovers before kickoff.

NASA will also host a virtual webinar about Artemis for the blind and low-vision community at 2pm ET on Friday, Oct. 2. The webinar will cover the RS-25 engine, the Artemis missions, and accessibility in space and science. Registration closes Friday, Sept. 25.
