Few things get local greenspace lovers more hyped than the upcoming improvements and beautification of our beloved Memorial Park — which is currently undergoing a major transformation. While many of the updates and facelifts are years off, one of the most innovative ventures has reached a new milestone in the much-anticipated Land Bridge and Prairie project.

Installation of the first tunnel arches has started as of December 9, according to the Memorial Park Conservancy. Marked by two separate, 35-foot tall mounds, the Land Bridge will serve as a major connector for park users and wildlife between the north and south sides of the park, Additionally, it will offer new gathering spaces with scenic views of Houston and the project's expansive prairie network.

Once the project is completed, vehicular traffic will traverse a new alignment of Memorial Drive via tunnels through the Land Bridge — two tunnels below each of the mounds (one for each direction of travel), according to a press release. The arch segments now being erected south of existing Memorial Drive are for the two tunnels through the eastern-most mound.

Next up will be erection of the west mound arches; all tunnels are slated for completion and open to traffic by fall of 2021.

These tunnels boast an innovative edge. While most are built through existing hillsides or below ground, the Land Bridge tunnels will be set at the same grade as the existing roadway, prior to installation of the earthwork for the mounds, per a release. The tunnels through the east and west mound measure 400 feet and 560 feet long respectively and are made up of some 620 separate panels, each of which weighs just under 50,000 pounds.

While excitement is looming, traffic on Memorial Drive is no doubt a concern. Sources at Memorial Park Conservancy assure that Memorial will remain open throughout the duration of Land Bridge and Prairie construction. Within the project area, traffic has been reduced from three lanes to two each way.

All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete. The new road alignment with three lanes restored each way will be complete in September 2021, while the Land Bridge is slated for substantial completion by October 2022.

Meanwhile, trees removed from the Land Bridge and Prairie project area (a major concern for locals) will be relocated in areas of the park designated for reforestation, or repurposed as either compost or toewood for streambank stabilization, in keeping with the Master Plan provisions.

Houston park breaks ground on innovative land bridge

now building

Last week, Memorial Park made headlines when it triumphantly opened its lush and verdant Eastern Glades. The 100-acre destination transformed largely inaccessible green space into a destination offering up picnic areas, native wetlands, a savanna, a pine-hardwood forest, green spaces, and miles of accessible trails.

Now, the Memorial Park Conservancy has announced that construction has begun on Memorial Park's Land Bridge and Prairie project. The 100-acre project, slated for completion in late 2022, will create a new community space with enhanced recreation opportunities for park users with "unmatched vantage points of urban skyline views," according to a press release. Memorial Park's prairie, which adjoins the Land Bridge to the north and the south, aims to re-establish endangered native Gulf Coast prairie, savanna, and wetlands.

The Land Bridge and its corresponding prairie are part of the Memorial Park Master Plan, made possible by a $70 million gift from the Kinder Foundation, and associated the Ten-Year Plan.

Commuters, no need to worry: Memorial Drive will remain open throughout the duration of Land Bridge and Prairie construction. Traffic will be reduced from three lanes to two each way beginning September, while a new section of Memorial Drive and the tunnel arch structures for the Land Bridge are completed directly south of the operating lanes.
All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete, according to a release.

Additionally, per the conservancy, the Land Bridge will:


Provide safety and connectivity
This will benefit both humans and animals crossing Memorial Drive. The Land Bridge will establish two dynamic greenspace connections over Memorial Drive that reunite the north and south sides of the Park while expanding the existing trail network and providing increased connectivity within the Park. While the Land Bridge will provide connectivity for Park visitors and wildlife over Memorial Drive, a stream corridor constructed through the Prairie and a culvert will provide connectivity under Memorial Drive. Together these elements will provide much-needed wildlife connectivity within Houston's largest urban wilderness park and to the natural Buffalo Bayou corridor.

Restore nearly 45 acres of native coastal prairie
This will establish a more resilient ecology during natural disruptions and improve animal habitats. Native coastal prairie is one of the most endangered ecosystems in North America, with less than 1 percent of its historic range remaining today. These forthcoming ecosystems will be home to numerous species of flora and fauna.

Create a new destination for visitors
New opportunities include nature education, leisure walking, interval running and cycling, stargazing, relaxing, and more.

Improve stormwater management
The project will detain stormwater that flows through Memorial Park to Buffalo Bayou during heavy rain events, lessening the impact of peak storms. A stream channel constructed through the site, along with the network of native prairie and savanna, will support greater regional biodiversity and act as a green sponge, helping to absorb and clean stormwater. The constructed wetlands will help to purify water and reduce roadway pollutants that would otherwise be released into the watershed.

"From aiding with critical stormwater management to granting people and wildlife safer crossing over Memorial Drive to providing a dynamic outdoor destination for all visitors, the Land Bridge and Prairie will be an asset not just for Memorial Park but for all Houstonians," said Mayor Sylvester Turner in a statement. "It's about unifying both sides of the Park and giving people a new landmark that they can be proud of and use to enjoy nature."

3 ways the Memorial Park Conservancy renovations are innovative

Park of the future

Memorial Park is undergoing a huge transformation that is mixing a little bit of old with the new.

The Memorial Park Master Plan includes adding breathtaking new projects — like water features, a new athletic complex, and more — as well as conservation efforts that restore parts of the land that were native coastal prairie. The project is a collaborative effort between Memorial Park Conservancy, Uptown Houston TIRZ, and Houston Parks and Recreation Department to redevelop the 1,500-acre park.

The Master Plan is set to deliver a series of projects ahead of 2028, and there are a few initiatives that are innovative and different from other urban parks' transformations, notes MPC's president and CEO Shellye Arnold.

The Land Bridge

A big part of Memorial Park's transformation is restoring the park to native species and ecosystems.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," Arnold says. "This serves important stormwater purposes."

In order to connect two native coastal prairie lands on either side of Memorial Drive, MPC is building a unique 30-foot-high land bridge the size of three-and-a-half football fields. The space will be large enough that you don't even realize you're standing over a busy street, Arnold says.

The prairies will serve an important purpose for rainwater collection — a growing need within the city of Houston.

"We're channeling [rainwater] into this prairie where some of it can be absorbed, cleansed, slowed down," says Arnold. "And then what doesn't get slowed down and absorbed can flow through the prairie [on the other side], which is even bigger."

The Land Bridge also serves another purpose that park goers have wanted, Arnold says: Connectivity.

"[They] want access across the Memorial Drive — [they] want to safe access, and so this is the response. It's a pretty bold and visionary response," Arnold says.

BioCycling

In 2011, a major drought decimated the park and areas saw losses of 50 to even 90 percent of the canopy of trees. MPC and its team saved what could be saved, and the rest is serving a new purpose to the park.

"We took the trees that we lost on the drought that people felt such a tremendous loss for and ground them all up, and they are in a biocycle in a two-acre area in the back of the park," Arnold says.

The soil created — some of which includes manure from the animals at the Houston Zoo — has already been used on some plants in the park, and Arnold says those plants are thriving.

"It's cool that those those trees are giving life to the park," Arnold says.

Invasive species of trees that are plucked from out of the park are also being ground up and used in the same way.

"There isn't anything this big like this in an urban park setting like this kind of recycling effort," she says.

The biocycling process is scalable too.

"We could open this up to other organizations," Arnold says. "It's so much better ecologically to take trees and grind them up and use it inside the space rather than haul them out to landfill way outside of town and dump them."

The benefit to the program is that MPC can retain some of the soil it produces for these other organizations and use it on site.

Biodiversity initiatives and research

When putting the plans in place, MPC and its partners called on 25 of the best ecologists, as well as 50 more park and other types of consultants specializing in everything from insects and wildlife to prairies and trees.

Just as the Land Bridge is creating new prairie space, other initiatives throughout the park will be focused on eliminating invasive species and bringing back the natural ecosystem of the park.

The Easter Glades project, which is set to deliver next year, will have a habitat for fish, and will not allow any fishing or boating. Carolyn White, conservation director at MPC, is working with the Texas Wildlife Association to bring in the right species of fish.

Arnold says that MPC works with other organizations in an innovative way to bring native plants into MPC, since the park has the space for these organizations to use to cultivate and propagate plants.

"They bring their native plants and they grow them with their volunteers, and they leave us a little bit here," Arnold says. "We could never buy enough native plants to go inside this park."

Elon Musk vows to launch solar-powered data centers in space

To Outer Space

Elon Musk vowed this week to upend another industry just as he did with cars and rockets — and once again he's taking on long odds.

The world's richest man said he wants to put as many as a million satellites into orbit to form vast, solar-powered data centers in space — a move to allow expanded use of artificial intelligence and chatbots without triggering blackouts and sending utility bills soaring.

To finance that effort, Musk combined SpaceX with his AI business on Monday, February 2, and plans a big initial public offering of the combined company.

“Space-based AI is obviously the only way to scale,” Musk wrote on SpaceX’s website, adding about his solar ambitions, “It’s always sunny in space!”

But scientists and industry experts say even Musk — who outsmarted Detroit to turn Tesla into the world’s most valuable automaker — faces formidable technical, financial and environmental obstacles.

Feeling the heat

Capturing the sun’s energy from space to run chatbots and other AI tools would ease pressure on power grids and cut demand for sprawling computing warehouses that are consuming farms and forests and vast amounts of water to cool.

But space presents its own set of problems.

Data centers generate enormous heat. Space seems to offer a solution because it is cold. But it is also a vacuum, trapping heat inside objects in the same way that a Thermos keeps coffee hot using double walls with no air between them.

“An uncooled computer chip in space would overheat and melt much faster than one on Earth,” said Josep Jornet, a computer and electrical engineering professor at Northeastern University.

One fix is to build giant radiator panels that glow in infrared light to push the heat “out into the dark void,” says Jornet, noting that the technology has worked on a small scale, including on the International Space Station. But for Musk's data centers, he says, it would require an array of “massive, fragile structures that have never been built before.”

Floating debris

Then there is space junk.

A single malfunctioning satellite breaking down or losing orbit could trigger a cascade of collisions, potentially disrupting emergency communications, weather forecasting and other services.

Musk noted in a recent regulatory filing that he has had only one “low-velocity debris generating event" in seven years running Starlink, his satellite communications network. Starlink has operated about 10,000 satellites — but that's a fraction of the million or so he now plans to put in space.

“We could reach a tipping point where the chance of collision is going to be too great," said University at Buffalo's John Crassidis, a former NASA engineer. “And these objects are going fast -- 17,500 miles per hour. There could be very violent collisions."

No repair crews

Even without collisions, satellites fail, chips degrade, parts break.

Special GPU graphics chips used by AI companies, for instance, can become damaged and need to be replaced.

“On Earth, what you would do is send someone down to the data center," said Baiju Bhatt, CEO of Aetherflux, a space-based solar energy company. "You replace the server, you replace the GPU, you’d do some surgery on that thing and you’d slide it back in.”

But no such repair crew exists in orbit, and those GPUs in space could get damaged due to their exposure to high-energy particles from the sun.

Bhatt says one workaround is to overprovision the satellite with extra chips to replace the ones that fail. But that’s an expensive proposition given they are likely to cost tens of thousands of dollars each, and current Starlink satellites only have a lifespan of about five years.

Competition — and leverage

Musk is not alone trying to solve these problems.

A company in Redmond, Washington, called Starcloud, launched a satellite in November carrying a single Nvidia-made AI computer chip to test out how it would fare in space. Google is exploring orbital data centers in a venture it calls Project Suncatcher. And Jeff Bezos’ Blue Origin announced plans in January for a constellation of more than 5,000 satellites to start launching late next year, though its focus has been more on communications than AI.

Still, Musk has an edge: He's got rockets.

Starcloud had to use one of his Falcon rockets to put its chip in space last year. Aetherflux plans to send a set of chips it calls a Galactic Brain to space on a SpaceX rocket later this year. And Google may also need to turn to Musk to get its first two planned prototype satellites off the ground by early next year.

Pierre Lionnet, a research director at the trade association Eurospace, says Musk routinely charges rivals far more than he charges himself —- as much as $20,000 per kilo of payload versus $2,000 internally.

He said Musk’s announcements this week signal that he plans to use that advantage to win this new space race.

“When he says we are going to put these data centers in space, it’s a way of telling the others we will keep these low launch costs for myself,” said Lionnet. “It’s a kind of powerplay.”

Johnson Space Center and UT partner to expand research, workforce development

onward and upward

NASA’s Johnson Space Center in Houston has forged a partnership with the University of Texas System to expand collaboration on research, workforce development and education that supports space exploration and national security.

“It’s an exciting time for the UT System and NASA to come together in new ways because Texas is at the epicenter of America’s space future. It’s an area where America is dominant, and we are committed as a university system to maintaining and growing that dominance,” Dr. John Zerwas, chancellor of the UT System, said in a news release.

Vanessa Wyche, director of Johnson Space Center, added that the partnership with the UT System “will enable us to meet our nation’s exploration goals and advance the future of space exploration.”

The news release noted that UT Health Houston and the UT Medical Branch in Galveston already collaborate with NASA. The UT Medical Branch’s aerospace medicine residency program and UT Health Houston’s space medicine program train NASA astronauts.

“We’re living through a unique moment where aerospace innovation, national security, economic transformation, and scientific discovery are converging like never before in Texas," Zerwas said. “UT institutions are uniquely positioned to partner with NASA in building a stronger and safer Texas.”

Zerwas became chancellor of the UT System in 2025. He joined the system in 2019 as executive vice chancellor for health affairs. Zerwas represented northwestern Ford Bend County in the Texas House from 2007 to 2019.

In 1996, he co-founded a Houston-area medical practice that became part of US Anesthesia Partners in 2012. He remained active in the practice until joining the UT System. Zerwas was chief medical officer of the Memorial Hermann Hospital System from 2003 to 2008 and was its chief physician integration officer until 2009.

Zerwas, a 1973 graduate of the Houston area’s Bellaire High School, is an alumnus of the University of Houston and Baylor College of Medicine.
