Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

Two astronauts recently received Presidential Medals of Freedom from President Joe Biden for their leadership in space.

Ellen Ochoa, the former center director and astronaut at the NASA's Johnson Space Center in Houston, and Jane Rigby, senior project scientist for NASA’s James Webb Space Telescope, were honored at the White House on May 3.

Ochoa spent 30 years with NASA, which included being the 11th director of JSC, deputy center director of JSC, and director of Flight Crew Operations. She served on the nine-day STS-56 mission aboard the space shuttle Discovery in 1993, and became the first Hispanic woman in space. She flew four more times to space with STS-66, STS-96, STS-110, and more.

“I’m so grateful for all my amazing NASA colleagues who shared my career journey with me,” Ochoa says in a NASA news release. Read more.

New VC firm aims to be the bridge between promising startups and Houston's innovation ecosystem

Houston innovators podcast Episode 236

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."


With his background that spans from the United States Military to academia and corporate venture, Ellis has had seats on nearly every side of the innovation table. But he says he was called to invest in founders of color after the murder of George Floyd. He says he also realized how much money was being left on the table by overlooking these innovators.

As one of the most diverse cities and the fourth largest city in the country, Houston is the place for Ellis's mission.

"The mission of South Loop is to become the preeminent source of venture capital dollars for underrepresented, diverse teams nationally to serve as a beacon for the best underrepresented talent and to enable them to be successful through leveraging the unique resources and talent of Houston," Ellis says. "A big part of our mission is also to help catalyze Houston as an ecosystem for tech entrepreneurship."

South Loop has six portfolio companies, including Houston-based Milkify, a breast milk freeze-drying service that went on to pitch and receive an investment on Shark Tank. Ellis says the firm expects to announce a handful of new investments over the next year or so. On the show, he explains more on what types of investment opportunities he's looking for and how founders can get in touch.

"The innovation is in the insight," he says. "We look to activate this community because we strongly believe in the power of founder insight."

UH secures $5M in philanthropic gifts to bolster engineering, nursing

major gifts

The University of Houston has received two significant philanthropic gifts to advance innovation and healthcare, the college announced this month.

Manmohan Singh Kalsi and Marie-Luise Schubert Kalsi granted $4 million to UH’s Cullen College of Engineering to support endowed and current funds for graduate fellowships and industry interest in the mechanical and aerospace fields.

The gift is the Department of Mechanical and Aerospace Engineering’s largest donation in years, according to UH, and will establish two endowed professorships to attract and retain leading faculty. It will also create the Kalsi Faculty Research Fund, which aims to take emerging research to the next level.

Additionally, UH says it will also bring industry experts to campus to present and collaborate with students via the forthcoming Kalsi Seminar Series.

Manmohan Kalsi earned both his master’s degree and Ph.D. in mechanical engineering from UH. He went on to found Sugar Land-based Kalsi Engineering in 1978, which pioneered hydrodynamic rotary sealing technology and valve technology for nuclear power plants. In 2014, he established an endowed professorship within Cullen College in honor of the late UH professor Gabriel Fazekas.

"This gift provides a tremendous boost to our department's strategic momentum,” Karolos Grigoriadis, chair of the Department of Mechanical and Aerospace Engineering, said in a news release. “By simultaneously supporting faculty, graduate researchers and collaborative seminars, the Kalsis are strengthening every part of our research enterprise and creating new opportunities for discovery, collaboration and student mentorship.”

Meanwhile, Houston’s The Hamill Foundation also gave a $1 million gift to UH’s Andy and Barbara Gessner College of Nursing. The funds will establish The Hamill Foundation Endowed Professorship in Community Care Nursing, to support a faculty member focused on community-based nursing education, partnerships, research, and outreach to underserved communities in Houston.

Additionally, the funding will go toward efforts to address nurse shortages through the newly established UH Health program. The Hamill Foundation has donated $6 million previously to UH through the years, but the latest $1 million is the largest single investment from the foundation to date.

“The Hamill Foundation continues to help us raise the bar for nursing education and address the nursing shortage,” Kathryn Tart, founding dean and professor at Gessner College and Humana Endowed Dean's Chair in Nursing, said in a news release. “The enduring commitment and generosity of The Hamill Foundation allow us to answer the call and educate generations of competent and caring nursing professionals.”

Both of the recent gifts help fund UH’s $1 billion Can’t Stop Houston: The Centennial Campaign. As of September, the university had raised more than $881 million. UH turns 100 years old in March 2027.

SpaceX's supersized Starship rocket launches into orbit for first time

Out in Space

SpaceX launched its enormous Starship into orbit for the first time Monday, September 28, and successfully delivered the most advanced Starlink satellites yet, but cut the flight short to ensure safety.

The spacecraft reentered over the Pacific and splashed down north of Hawaii three hours after blasting off from Texas. The company had been aiming for a 10-hour flight, spanning six full laps around Earth, to prove its readiness for NASA’s Artemis moon program.

Starship tipped over and erupted in flames upon splashdown, a dramatic end to the mission.

Elon Musk's Starship almost didn't make it to orbit when one of its engines shut down prematurely. But with everything else working well and the bad engine no longer needed, flight controllers decided, after several tense minutes, to proceed as planned.

“Starship is orbital,” Mission Control announced to cheers.

NASA Administrator Jared Isaacman congratulated SpaceX on reaching orbit and “managing every step in a safe, responsible and especially inspirational way.”

Rocket carries 26 of Musk's most advanced Starlink satellites

Musk’s showpiece rocket — the biggest and most powerful ever built — carried 26 of the latest Starlinks to join the 11,000 older models already providing internet service. They popped out of the spacecraft one by one, drawing more cheers from the SpaceX crowd at the Starbase launch site.

The decision to end the flight early came soon afterward. SpaceX said hours later in an online update that the decision was made “out of an abundance of caution” because of the early engine trouble.

It was Starship’s 14th full-scale launch from Texas’ southern tip in three years. Earlier test flights ventured no farther than the Indian Ocean halfway around the world, often crashing in flames and briefly skimming space.

This time, the intent was for SpaceX to circle the globe from an altitude of 170 miles (275 kilometers) — not just once but six times over almost 10 hours, ending with a Pacific splashdown near Chile. While Starship achieved the proper orbit, zipping along at 17,500 mph (28,000 kph), flight controllers opted to play it safe and bring it back several hours sooner, after just a couple of laps.

The first-stage booster was never meant to return to the Starbase launch site either, dropping instead into the Gulf of Mexico within minutes of the morning liftoff.

SpaceX wants to ensure that everything works before flying Starship back to Starbase. If the spacecraft breaks apart over land and rains debris onto people, “our popularity would diminish very rapidly,” Musk said at a business summit earlier this month. “That’s why we’re being extremely cautious here.”

Depending on the findings from Monday's orbital debut, the next Starship could return to the launch pad, where giant mechanical arms would grab the hovering spacecraft. If the catch works — Musk gives it even or slightly better odds — then SpaceX will refly the spacecraft by year’s end or early next year.

The 407-foot (124-meter) rocket was designed from the start to be fully reusable, a key to lowering launch costs. SpaceX managed to salvage the last Starship from the Indian Ocean in July. Engineers modified the newly launched Starship’s heat shield based on hands-on inspections of the recovered spacecraft, which is being tugged back to Starbase.

SpaceX wants Starship to be certified for orbital flight

SpaceX is pressing hard to certify Starship for orbital flight, a vital step toward moon and Mars travel.

NASA’s Artemis III mission is coming up as soon as next summer, a triple-launch docking exercise in orbit around Earth between an Orion capsule full of astronauts and competing lunar landers. Jeff Bezos’ Blue Moon would blast off first, followed by Orion — which would close in for a linkup — and then Musk’s Starship for a docking with Orion once Blue Moon is unleashed.

The next mission, Artemis IV, is slated for no sooner than 2028 and would have astronauts landing on the moon in either Blue Moon or Starship, whichever is ready first. Subsequent moonshots will alternate between the two billionaires’ landers.

Musk originally developed Starship for Mars, intending to launch scores of them with the red planet’s first settlers. For now, he plans to focus on the moon and use Starship to haul satellites into orbit by the truckload, phasing out the company’s frailer Falcon 9 rocket within several years. A second Starship launch site is nearing completion at Florida’s Kennedy Space Center and a third is planned for Louisiana.
