Editor's note: Undocking was delayed again on April 19, and a new timeline has not been announced. The original story is below.

After spending 12 days in space, a historic commercial space mission will splash back down on Earth this week.

Houston-based Axiom Space’s first mission Axiom mission 1 (Ax-1), which took off April 8 and connected to the International Space Station, has announced its plans for undocking and splashdown.

After some initial bad weather postponed the process, the four-member private astronaut crew now is aiming to undock at about 9 pm tonight, April 19, and then land off the coast of Florida at around 2:24 pm tomorrow, April 20. Just like launch, the coverage of both events will be available at Axiom's website.

The mission on SpaceX’s spacecraft sent four multinational private astronauts — Commander Michael López-Alegría, Pilot Larry Connor, Mission Specialist Eytan Stibbe, and Mission Specialist Mark Pathy — to the ISS to conduct research and familiarize Axiom with launch, docking, and more.

Axiom Space, which reached $1 billion valuation and joined the Houston unicorn club last year after a $130 million investment round, is working on the first commercial space station to replace the ISS. The first launch of that mission is expected in late 2024. In the meantime, Axiom has a series of commercial launches to the existing station currently in orbit in order to prepare for development and orchestration of Axiom Station.

The Ax-1 mission, which has provided daily updates, has conducted over 20 research projects and even hit a few milestones, including:

  • The first-ever music duet performance in space — Commander López-Alegría and Neo-Classical Piano Prodigy BLKBOK made music and space history with their piano and keyboard duet
  • The Aging and Heart Health investigation, an experiment from the Mayo Clinic — a study that analyzes human cells for genetic markers of cellular aging and explores cardiac-like cells' adaptation to microgravity
  • Observation of Transient Luminous Events — Specialist Stibbe completed a space observation experiment and photographed a lightning storm over Darwin, Australia, to enhance understanding of the electrical processes in the atmosphere and to determine whether there’s a connection with climate change
  • Testing of the Holoportation system — Mission Specialist Pathy set up two-way AI technology that will allow the ability of future crew members to explore deep space with the ability to virtually bring friends, family, and physicians close with them so that they can get an on-Earth experience
  • Several outreach calls to Earth to STEM students from around the world — this included a call to children at Space Center Houston

Axiom shares more details on its mission research projects — which span technologies such as future space habitats, cancer research, and devices to purify air on space stations — online.

“As the first step on a path to building a diverse, thriving economy in low-Earth orbit, Axiom has partnered with leaders in academia and industry to bring new users and new investigations in research to the space station,” says Christian Maender, director of In-space Manufacturing and Research for Axiom Space, in a news release. “The collection of biological and technological tests during the Ax-1 mission represent a breadth of research that will inform everything from human health considerations to novel infrastructure and design for our future homes away from Earth, beginning with Axiom Station.”

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
