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.”

Houston startup lands $10M to power up electrician staffing platform

money moves

Houston-based Buildforce, which provides a tech-enabled staff platform geared toward electricians and electrical contractors, has raised a $10 million Series A round led by Houston’s Saepio Capital.

Other investors in the round include Blue Heron Capital, Revolution’s Rise of the Rest Seed Fund, S3 Ventures and Chicago Ventures.

Buildforce says the funding will help fuel its national expansion and further development of its technology.

The startup, founded in 2019, connects electricians with electrical contractors for commercial and industrial construction projects. Buildforce’s mobile app helps electricians find and carry out work, and a web app helps electrical contractors find and manage electricians.

“This financing is a major milestone in furthering our mission to help people dedicated to a career in the construction trades lead more secure and fulfilling lives,” co-founder and CEO Moody Heard said in a news release.

Buildforce focuses solely on the electrical trade within the construction sector.

Nick Graziano, principal at Blue Heron, says the shortage of electricians is intensifying as demand for electricians accelerates, driven by data center construction, infrastructure development and energy transition initiatives.

The U.S. Bureau of Labor Statistics estimates the U.S. will need to hire about 80,000 new electricians per year through 2032 to catch up with demand. According to the National Electrical Contractors Association, the U.S. is grappling with a current shortage of 50,000 electricians.

A 2026 economic report from asset manager BlackRock says the electrical trade is expected to be the single fastest-growing employment category in the U.S. labor market over the next 10 years.

“Buildforce is capitalizing on a clear opportunity in America’s generational infrastructure buildout. We believe their mission to use technology to improve lives in the construction space will allow them to make a positive long-term impact on a large and important labor market,” added Jaan Bains, managing partner at Saepio Capital.

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.
