Intuitive Machines lands $1M grant to expand robotics operations

Expansion mode

Houston-based Intuitive Machines is expanding its operations around the country.

The space tech company—which has offices and labs in Texas, California, Arizona, Colorado and Maryland—announced that it has received a $1 million grant from Maryland Gov. Wes Moore through the state's Build Our Future Grant. The funding will go toward expanding Intuitive Machines’ Super Cislunar Robotics Assembly Building (Supa-CRAB) Mechanisms and Robotics Center of Excellence in Anne Arundel County.

The company will move into a 69,000-square-foot facility and build out additional lab and office space. It will also procure equipment that will allow for in-house Assembly, Integration and Test (AI&T) activities, according to a news release. Intuitive Machines says the expansion will take place this fall.

“This collaboration shows how industry, state programs, and education can reinforce one another,” Steve Altemus, CEO of Intuitive Machines, said in the release. “Maryland invests in innovation, companies grow and hire, students gain experience, and communities benefit from new opportunities and long-term career pathways. Together with Governor Moore, the state of Maryland, and Anne Arundel County leaders, we are building a permanent path to long-term lunar operations, an advanced robotics and mechanisms center of excellence, and a technology edge for our nation.”

Intuitive Machines first launched operations in Maryland in 2021 and has since expanded five times in the state. The company officially opened its robotics and mechanisms facility in 2024.

The Maryland team has built robotics and mechanisms for the Nova-C landers and IM-1 and IM-2 missions. In the future, Intuitive Machines expects the Maryland team to work on its IM-3 Rover Deployment Mechanism (RDM), a 360 pan-tilt camera for panoramic views, the Main Engine Gimbal (MEG), and the company's first data relay satellite, known as Altus-1.

Intuitive Machines moved into a new $40 million headquarters at the Houston Spaceport in 2023. The company announced an expansion of its lease last year.

The company announced a $175 million equity investment to fuel growth in March. It's since landed a $180 million NASA CLPS award to deliver seven payloads to the moon's Mons Malapert on the IM-5 mission.

5 Houston universities named best in the world on new U.S. News list

Top of the Class

Five Houston-area universities have been named among the best universities worldwide in U.S. News & World Report's just-released comprehensive list for 2026-2027.

U.S. News' Best Global Universities report ranks more than 2,250 schools based exclusively on their academic research performance and international reputation. Only 275 universities from the U.S. were included in the global ranking, and 21 based in Texas.

Harvard University topped the list for 2026-2027, and the Massachusetts Institute of Technology and Stanford University claimed the coveted No. 2 and No. 3 spots worldwide.

Houston's Baylor College of Medicine topped the list of the best local schools, and it ranked as the 144th best university in the world.

Here's how the rest of Houston's local institutions ranked:

No. 201 – Rice University
No. 324 – University of Texas Health Science Center Houston
No. 390 – University of Houston
No. 599 – University of Texas Medical Branch Galveston

In a statement explaining global university trends, the managing editor for Education at U.S. News, LaMont Jones, Ed.D., said schools in the U.S. have continued to rank "disproportionately high" while major universities from other countries in China and South America are starting to catch up.

"The continuing strength of [American university] reputations and academic research are, for the most part, unmatched," he said. "It's why students all over the world flock here to learn."

Top-ranking Texas universities
The University of Texas at Austin ranked No. 1 statewide and No. 56 worldwide, further cementing the university's reputation as the top choice for students seeking a higher education in Texas.

Earlier in June, UT Austin ranked No. 35 in a separate list of the best universities in the world from the Center for World University Rankings, which compared 2,000 schools globally.

Here's where other Texas universities stand among the top 1,000 in this year's global rankings:

No. 113 – University of Texas Southwestern Medical Center, Dallas
No. 177 – Texas A&M University, College Station
No. 296 – University of Texas at San Antonio
No. 451 – Baylor University, Waco
No. 503 – University of Texas at Dallas
No. 562 – Texas Tech University, Lubbock
No. 739 – University of North Texas, Denton
No. 975 – University of Texas at Arlington
No. 944 – Southern Methodist University, Dallas

Additionally, six Texas universities ranked outside the top 1,000: University of Texas Rio Grande Valley (No. 1,153); University of Texas El Paso (No. 1,238); Texas State University in San Marcos (No. 1,531); Texas Tech University Health Sciences Center in Lubbock (No. 1,871); Texas Christian University in Fort Worth (No. 1,906); and Sam Houston State University in Huntsville (No. 2,141).

Rice student startup lands $1.85M to launch medical drone network

critical cargo

Students at Rice University have developed a medical cargo drone transport system to help deliver sensitive medical supplies and improve mobile healthcare efforts.

Haast Autonomous is the brainchild of graduating seniors Ege Halac, Jason Chen and Santiago Brent, who got their venture idea off the ground with help from the Liu Idea Lab for Innovation and Entrepreneurship (Lilie) Summer Venture Studio. The founders have developed the prototype at Rice’s Oshman Engineering Design Kitchen (OEDK) with fellow Rice researchers Felix Hasson, Ethan Javedan, Kenna Sanders and Caden Schmidt.

The startup has raised $1.85 million in pre-seed funding, according to Rice. The founders plan to focus on Haast full-time following graduation. They said they aim to launch pilot trials in 2027 and head to market later that year.

“We need better alternatives for a fast, safe and on-demand system of transport for life-critical cargo,” Halac said in a news release from Rice.

The Haast team has developed a custom aircraft with software that manages dispatch, routes, and chain of custody to assist in how materials move between sites in centralized medical systems. Generally, the transportation of medical supplies and materials between facilities and points of care relies on ground shipping or expensive air transport.

Haast Autonomous’ aircraft can take off and land vertically, and is designed around a mission profile of 50 to 62 miles. It can carry a payload of at least 5 pounds, with future versions intended to scale up in size. It also includes a built-in payload bay that regulates temperature, pressure, vibration and tilt to protect sensitive contents such as patient samples, antivenom or poisoning kits and radioligands or other therapies, according to Rice.

At first, the company envisioned the mission to be centered around transplants, but saw the product being best suited for a variety of operations.

“What we realized is that the platform we are building is suited for medicine, but it really underlies a much larger problem of mission-critical transport across industries,” Brent added in the news release. “We are building the fastest, most secure logistics chain for the world’s most sensitive cargo.”

Haast Autonomous was recognized at the 2026 Oshman Engineering Design Showcase and Competition, where it won Best Aerospace or Transportation Technology. It also performed well in the 2026 Napier Rice Launch Challenge.

In the future, Haast Autonomous plans to deploy a fleet of aircraft. The software will be designed to assist hospitals in requesting flights and tracking deliveries in real time.

“The drone is only part of the solution,” Chen also added in the release. “What matters is moving something from point A to point B in a way that fits into how hospitals already operate.”
