A Houston tech company working on an engine to enable hypersonic flights has reported its latest milestone.

Venus Aerospace announced that it's successfully ran the first long-duration engine test of their Rotating Detonation Rocket Engine in partnership with Defense Advanced Research Projects Agency, or DARPA.

The RDRE engine Venus is working on is uniquely designed and a first in the field. It has an additional 15 percent efficiency over traditional rocket engines.

"As we continue to push towards our ultimate mission of high-speed global flight, this is an important technical milestone for having a flight-ready engine," Andrew Duggleby, CTO and co-founder of Venus Aerospace, says in the news release. "I'm incredibly proud of our team as they continue to push forward on this world-changing technology."

The test results are a big win, as the RDRE had previously only been tested in a short-duration capacity. DARPA is just one of several U.S. Government agencies that has contracts with Venus.

"The successful test is a testament to our team's dedication and expertise. We're building something special here at Venus, in large part because we have the right people and the right partners," Sassie Duggleby, CEO and co-founder of Venus Aerospace, adds. "I can't say enough about our collaboration with DARPA and the role they played in helping us make this leap forward."

Last summer, Venus added a new investor to its cap table. Andrew Duggleby founded Venus Aerospace with his wife and CEO Sassie in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. Sassie joined the Houston Innovators Podcast a year ago to explain her company's mission of "home for dinner."

Houston startup with hypersonic engine tech adds new investor

it's rocket science

A Houston-based company that's developing an engine that'll enable one-hour global transportation has announced its latest investor.

Venus Aerospace released the news that Silicon Valley venture capital firm, Airbus Ventures, has joined its team of investors. The supersonic combustion engine technology — more akin to a rocket's engine than an airplane's — is revolutionary because allows for travel at a higher elevation. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally.

“Venus has developed the world’s first liquid-propellant rotating detonation rocket engine (RDRE) with a double-digit percentage increase in efficiency over standard regular engines, making the hypersonic economy possible,” says Sassie Duggleby, CEO and co-founder of Venus, in a news release. “We’re delighted to bring Airbus Ventures into the Venus family and look forward to growing our collaboration as we harness the future of hypersonic flight.”

Duggleby founded Venus Aerospace with her husband and CTO Andrew in 2020, before relocating to the Houston Spaceport in 2021. Last year, Venus raised a $20 million series A round. That round, led by Prime Movers Lab, is being used to fund tech development and initial flight testing for building its Mach 9 hypersonic drone and Mach 9 spacecraft. Venus did not disclose how much their newest investor has contributed.

“In the world of RDREs, their pioneering approach — designing, building, and demonstrating the first liquid, storable-propellant fueled rotating detonation rocket engine — unlocks advanced aircraft capabilities and opens new vistas on our whole planetary system,” says Airbus Ventures Managing Partner Thomas d’Halluin in the release. “Venus’ compact, low mass, high efficiency engine capability will have an immediate impact on lunar and martian landers, space mobility and logistics, and deep space mission proposals.

"Here on Earth today, we will see unprecedented performance gains for drones of all kinds, and more practical and faster-than-anticipated opportunities for ultra-high-speed passenger and cargo rocket plane flights,” he continues.

Venus, which as has contracts with NASA and US Defense Agencies, has plans to test its technology this summer at its headquarters in the Houston Spaceport.

“With the strong support of Airbus Ventures now joining our investor syndicate, our next round will let Venus take the final step from lab to prototype as we fly our drone to Mach 3 under RDRE power," says Andrew Duggleby, in the release. “This will include long-duration engine runs this summer at Spaceport Houston, as well as the design, build, and flight of our drone with the broader Venus team and our incredible partners.”

Houston aerospace startup secures $20M series A investment round

money moves

A year after raising $3 million in seed funding, a Space City startup has closed its high-flying series A round to the tune of $20 million.

Venus Aerospace, which is working on a zero-carbon emission spaceplane that will enable one-hour global travel, closed its series A funding round led by Wyoming-based Prime Movers Lab. The firm has a few dozen breakthrough scientific companies in its portfolio, including another Houston-based, space-focused startup, Axiom Space. The round also saw participation from previous investors: Draper Associates, Boost, Saturn 5, Seraph Group, Cantos, The Helm & Tamarack Global.

Venus Aerospace was founded by Sarah "Sassie" and Andrew Duggleby, who serve as the company's CEO and CTO, respectively, in 2020 in California. The Texas A&M University alumni later moved the business into its current facilities in the Houston Spaceport.

"The U.S. is in the middle of a global race for hypersonic technology, and the breakthroughs being developed by Sassie, Andrew, and their team have numerous civilian and defense applications," says Prime Movers Lab General Partner Brandon Simmons in a news release. "Venus hit critical engine tests, vehicle design, and growth milestones that make me tremendously excited about the future of American hypersonic flight."

According to the release, the company will use the fresh funding on enhancing its three main technologies: a next-generation rocket engine, aircraft shape, and leading-edge cooling system, which allows for the Venus spaceplane to take off from existing spaceports.

"These recent advances in technology finally enable a spaceplane, a vehicle long imagined, but only now possible," says Andrew Duggleby in the release. "We will use this round of funding to get into flight testing and engine testing at Spaceport Houston. Bringing this technology forward into systems, drones and ultimately spaceplanes, it will take both new space veterans and bright new minds to solve. We've gone from impossible to hard, and this investment will allow us to knock down the next few steps."

The past year has represented significant growth for Venus, with developing contracts with the government and building out the company's team — and the company still has eight positions listed on its website. After building out and testing its technology, Venus also started a ground test campaign at Spaceport Houston.

"We are excited to continue our partnership with Prime Movers Lab and our other great investors. In the past year, with our initial funding, we have scaled from 3 people to 40. These are the world's best rocket scientists, engineers, and operators," says Sassie Duggleby in the release. "With this funding, we will continue to push forward toward our next technical milestones, hire great people, and scale our organization. We are excited to continue engineering the future of high-speed aviation."

Houston chemist lands $2M NIH grant for cancer treatment research

future of cellular health

A Rice University chemist has landed a $2 million grant from the National Institute of Health for his work that aims to reprogram the genetic code and explore the role certain cells play in causing diseases like cancer and neurological disorders.

The funds were awarded to Han Xiao, the Norman Hackerman-Welch Young Investigator, associate professor of chemistry, from the NIH's Maximizing Investigators’ Research Award (MIRA) program, which supports medically focused laboratories.

Xiao will use the five-year grant to develop noncanonical amino acids (ncAAs) with diverse properties to help build proteins, according to a statement from Rice. He and his team will then use the ncAAs to explore the vivo sensors for enzymes involved in posttranslational modifications (PTMs), which play a role in the development of cancers and neurological disorders. Additionally, the team will look to develop a way to detect these enzymes in living organisms in real-time rather than in a lab.

“This innovative approach could revolutionize how we understand and control cellular functions,” Xiao said in the statement.

According to Rice, these developments could have major implications for the way diseases are treated, specifically for epigenetic inhibitors that are used to treat cancer.

Xiao helped lead the charge to launch Rice's new Synthesis X Center this spring. The center, which was born out of informal meetings between Xio's lab and others from the Baylor College of Medicine’s Dan L Duncan Comprehensive Cancer Center at the Baylor College of Medicine, aims to improve cancer outcomes by turning fundamental research into clinical applications.

They will build upon annual retreats, in which investigators can share unpublished findings, and also plan to host a national conference, the first slated for this fall titled "Synthetic Innovations Towards a Cure for Cancer.”

Houston neighbor ranks as one of America's most livable small cities

mo city

Some Houston suburbs stick out from the rest thanks to their affluent residents, and now Missouri City is getting time in the spotlight, thanks to its new ranking as the No. 77 most livable small city in the country.

The tiny but mighty Houston neighbor, located less than 20 miles southwest of Houston, was among six Texas cities that earned a top-100 ranking in SmartAsset's 2024 " Most Livable Small Cities" report. It compared 281 U.S. cities with populations between 65,000 and 100,000 residents across eight metrics, such as a resident's housing costs as a percentage of household income, the city's average commute times, and the proportions of entertainment, food service, and healthcare establishments.

According to the U.S. Census Bureau, Missouri City has an estimated population of over 76,000 residents, whose median household income comes out to $97,211. SmartAsset calculated that a Missouri City household's annual housing costs only take up 19.4 percent of that household's income. Additionally, the study found only six percent of the town's population live below the poverty level.

Here's how Missouri City performed in two other metrics in the study:

  • 1.4 percent – The proportion of arts, entertainment, and recreation businesses as a percentage of all businesses
  • 29.9 minutes – Worker's average commute time

But income and housing aren't the only things that make Missouri City one of the most livable small cities in Texas. Residents benefit from its proximity from central Houston, but the town mainly prides itself on its spacious park system, playgrounds, and other recreational activities.

The Missouri City Parks and Recreation Departmen meticulously maintains 21 parks spanning just over 515 acres of land, an additional 500 acres of undeveloped parkland, and 14.4 miles of trails throughout the town, according to the city's website."Small cities may offer cost benefits for residents looking to stretch their income while enjoying a comfortable – and more spacious – lifestyle," the report's author wrote. "While livability is a subjective concept that may take on different definitions for different people, some elements of a community can come close to being universally beneficial."

Missouri City is also home to Fort Bend Town Square, a massive mixed-use development at the intersection of TX 6 and the Fort Bend Parkway. It offers apartments, shopping, and restaurants, including a rumored location of Trill Burgers.

Other Houston-area cities that earned a spot in the report include

Spring (No. 227) and Baytown (No. 254).The five remaining Texas cities that were among the top 100 most livable small cities in the U.S. include Flower Mound (No. 29), Leander (No. 60), Mansfield (No. 69), Pflugerville (No. 78), and Cedar Park (No. 85).

The top 10 most livable small cities in the U.S. are:

  • No. 1 – Troy, Michigan
  • No. 2 – Rochester Hills, Michigan
  • No. 3 – Eau Claire, Wisconsin
  • No. 4 – Franklin, Tennessee
  • No. 5 – Redmond, Washington
  • No. 6 – Appleton, Wisconsin
  • No. 7 – Apex, North Carolina
  • No. 8 – Plymouth, Minnesota
  • No. 9 – Livonia, Michigan
  • No. 10 – Oshkosh, Wisconsin

The report examined data from the U.S. Census Bureau's 2022 1-year American Community Survey and the 2021 County Business Patterns Survey to determine its rankings.The report and its methodology can be found on
