Jan. 10 (UPI) — High winds forced United Launch Alliance to scrub its launch plans for Wednesday afternoon.

ULA was originally scheduled to launch a spy satellite at 4 p.m. ET from California’s Vandenberg Air Force Base. The space company plans to give the launch another go tomorrow.

The mission will see ULA’s Delta IV Medium rocket carry NROL-47 spacecraft into low-Earth orbit. Once in orbit, the spacecraft will be operated by the U.S. National Reconnaissance Office.

“#DeltaIV #NROL47 mission was scrubbed today due to high ground winds. Launch is planned for Thursday, Jan. 11, from Vandenberg Air Force Base,” ULA tweeted. “The forecast shows a 90 percent chance of favorable weather conditions for launch.”

Launch time will once again be 4 p.m. ET.

“We are ready and eager to take on this Delta launch,” Col. Greg Wood, launch commander and vice commander of the Air Force’s 30th Space Wing, said in a statement earlier this week. “We are proud to provide this national defense capability, and every Team V member involved has tirelessly worked to ensure the launch is safe and successful.”

Vandenberg’s 4th Space Launch Squadron assisted ULA with launch preparations.

“The 4th Space Launch Squadron’s mission assurance technicians, engineers, and program managers are laser-focused on ensuring that all flight hardware, infrastructure, and facilities are ready to go for launch,” said Maj. Allen Varghese, 4th Space Launch Squadron director of operations. “Our squadron has worked side-by-side with ULA personnel over the past several months to ensure this mission’s success.”

On Sunday, a top secret government spacecraft launched by SpaceX reportedly failed to achieve a stable orbit. The government hasn’t confirmed whether the top-secret satellite did indeed fall out of orbit and reenter Earth’s atmosphere.

In the aftermath of the alleged failure, SpaceX claimed its rocket performed as expected, implying the blame for the Zuma mission lay elsewhere.

Sunday’s launch was SpaceX’s third classified mission. This week’s launch will be ULA’s 27th mission for the NRO. The mission offers ULA a chance to show why the aerospace company remains the government’s most trusted partner for top-secret missions.

Tomorrow’s launch will be live streamed. Coverage will begin at 3:40 p.m. ET.
