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."

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.

Houston space companies take off with new tech, deals and contracts

space update

Space City has had a busy month.

Houston-based aerospace institutions Venus Aerospace, Axiom Space, and Aegis Aerospace have each recently announced advancements in their respective fields that include expansions and new contracts from U.S. and international government agencies.

Here’s the latest:

Venus launches new test stand

Earlier this month, Venus Aerospace added infrastructure to support the ongoing progress of its Rotating Detonation Rocket Engine (RDRE) with the opening of its new propulsion test stand at the Houston Spaceport.

The Texas Space Commission's Space Exploration and Aeronautics Research Fund is funding the test stand, which is part of a larger effort from the state to increase investments in the aerospace economy. The ribbon-cutting event on Sept. 10 welcomed officials from Venus Aerospace, the Texas Space Commission, the Houston Spaceport, Houston business and local community leaders.

With the new stand, Venus will be able to test at higher thrust and for longer durations, which will allow the company to better replicate real-life conditions.

"Building and testing propulsion systems at this pace requires the right infrastructure around the technology," Sassie Duggleby, CEO and co-founder of Venus Aerospace, said in a news release. "We're grateful to the Texas Space Commission and the State of Texas for investing alongside companies like Venus. Public investment like this helps companies move faster and keeps critical aerospace capability growing here in Texas."

Venus closed a $91 million Series B in July and expanded its leadership team.

Axiom partners in Europe

Axiom Space has signed a memorandum of understanding with the European Space Agency for “sustained European access to low-Earth orbit (LEO)” following the retirement of the International Space Station, according to a news release from the company.

Under the agreement, Axiom and the ESA agreed to explore future astronaut missions on the ISS and Axiom Station, research, transportation and spacesuit partnerships. The organizations will explore using the ESA’s European Cargo Return service and potentially a future European crew vehicle to support operations at Axiom Station, the company's forthcoming commercial space station. The partnership could also involve Axiom's AxEMU spacesuit for orbital and lunar applications, according to the release.

“With the upcoming de-orbitation of the ISS, it is our duty to anticipate and prepare future solutions to ensure our access to low-Earth orbit,” Daniel Neuenschwander, director of human and robotic exploration at ESA, said in the release. “The two documents signed today underline both our commitment to safeguard our ability to pursue in-orbit science and to keep offering flight opportunities to our European astronaut corps, as well as the growing interest of international partners for our ongoing project to develop an autonomous European cargo vehicle.”

The announcement comes as Axiom has made several international moves this year. The company shared plans to establish Axiom Space Switzerland this summer and launched Axiom Space Japan in July.

"The path to a sustainable human presence in space runs through international collaboration — reliable supply chains, shared innovation, and partners who bring real capability," Jonathan Cirtain, CEO and President of Axiom Space, said in the release. "Europe's contributions to microgravity science and deep space technology make ESA exactly that kind of partner. This MoU strengthens our work together, and we look forward to ESA and its member states joining us as customers for future astronaut missions."

Aegis expands DoW deal

Webster, Texas-based Aegis Aerospace announced that it has won a new task order to continue supporting the U.S. Space Force’s Space Test Program.

The contract starts in October and covers designing, building, testing and operating Department of War payloads or equipment on NASA, government, and commercial launch vehicles and platforms. The contract was issued by the USSF Space Systems Command, Space Test Program under NASA Johnson Space Center’s Research, Engineering, and Mission Integration Services 2 (REMIS 2).

Currently, the company is working on three payload facilities on the ISS and has plans for two more in development.

“Aegis Aerospace is grateful to continue our exceptional payload integration support to the USSF and the STP to meet their critical mission objectives,” President Matt Ondler added in the release. “This work is more important than ever to maintain U.S. superiority in space. This new contract will take us beyond the current life of the ISS and see us integrate and test payloads on commercial space stations, free-flyers, and cislunar missions.”
