Nearly 45 years after it opened as a tribute to Houston's role in the moon landing, Tranquility Park may be getting a new liftoff.

During Mayor John Whitmire's State of the City address on Thursday, he announced his vision to elevate parks and public spaces, including transforming Tranquility Park behind City Hall on 400 Rusk Street.

Described as the "shadow of City Hall" in the heart of Downtown Houston, the space opened to the public in 1979 on the 10th anniversary of the historic moon landing. Its name was adapted from the Moon's Sea of Tranquility and pays homage to Neil Armstrong, "Houston, Tranquility Base here. The Eagle has landed." 

"Tranquility Park can and should be a better reflection of this great city's ambitions and achievements," he said. "This is one of the popular places where Houstonians gather to participate in our most cherished public events and parades."

The work on Tranquility Park started in November with better care and maintenance, officials noted in a news release. The city's Parks and Recreation Department and Public Works said soil, mulch and new sod was added at the oak tree's roots. Further repairs paved the way for wider upgrades to begin in March.
