After calling off the launch of Boeing Space’s Starliner spacecraft on Saturday with just minutes to go, NASA says it’s now aiming to ship the automobile on its first crewed mission at 10:52 a.m. ET on Wednesday, June 5.

United Launch Alliance’s (ULA) Atlas 5 rocket will launch NASA astronauts Butch Wilmore and Suni Williams aboard the Starliner from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

In a message posted on Sunday, NASA mentioned that technicians and engineers with ULA have spent the weekend assessing the launchpad’s floor help tools that encountered points throughout Saturday’s countdown, prompting the mission to be postponed.

“The ULA team identified an issue with a single ground power supply within one of the three redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage,” NASA mentioned. “All three of these chassis are required to enter the terminal phase of the launch countdown to ensure crew safety.”

As a part of the work to resolve the problem, the chassis containing the defective floor energy unit was eliminated, visually inspected, and changed with a spare chassis, NASA mentioned, including that there have been no indicators of any bodily injury. The house company mentioned {that a} full failure evaluation of the facility unit shall be carried out to higher perceive the basis reason for the incident. It additionally famous that the entire {hardware} is performing as anticipated following practical checkouts of the brand new chassis and the playing cards.

The U.S. Space Force’s forty fifth Weather Squadron predicts a 90% likelihood of favorable climate circumstances for Wednesday’s launch. If for any cause the flight fails to get underway on that day, there’ll be one other alternative for liftoff on the next day.

The plan is to fly the Starliner to the International Space Station (ISS). Wilmore and Williams will keep there for every week earlier than returning residence within the spacecraft in a parachute-assisted touchdown.

The Starliner has confronted years of delays, principally over technical concern, and has flown twice earlier than with out a crew. The first check, in 2019, failed to succeed in the ISS, whereas the second mission, in 2022, efficiently docked with the orbital laboratory.

The first crewed flight was purported to launch on May 6, however just a couple of hours from launch, engineers encountered a problem with the Atlas V rocket. In the next days, a helium leak was discovered on the Starliner, inflicting an extra delay. Several different launch targets have been and gone. NASA and Boeing Space — in addition to Wilmore and Williams — shall be hoping that the much-anticipated mission can lastly get underway on Wednesday.
