SpaceX delays Polaris Dawn launch again due to unfavorable weather
SpaceX so far hasn't set a new attempt date for the Falcon 9’s launch of Polaris Dawn from NASA’s Kennedy Space Center in Florida.

KENNEDY SPACE CENTER, Fla. – SpaceX has again delayed the launch date for two of its employees and two other private citizens on the Polaris Dawn mission, which will include the first private spacewalk.
On Monday, teams discovered a ground-side helium leak on the Quick Disconnect umbilical, a piece of equipment designed to detach from the rocket during takeoff. That prompted SpaceX officials to push back the launch date for the historic mission by one day.
SpaceX then scrubbed an attempt Tuesday and said they would try to launch Polaris Dawn from NASA's Kennedy Space Center in Florida early Wednesday morning. Late Tuesday night, SpaceX said they would stand down from that launch attempt "due to unfavorable weather forecasted in Dragon's splashdown area off the coast … of Florida."

Despite the delay, SpaceX teams are in high spirits and looking forward to the launch.
"Weather is going to be a challenge given launch and return requirements, Mission Specialist Sarah Gillis, who is part of the Polaris Dawn team, posted on X on Tuesday evening. "Scrubbing for the next few launch opportunities, but ready to go once a weather window opens!"

SpaceX said this will be Gillis' first human spaceflight, along with that of Mission Pilot Kidd Poteet and Mission Specialist and Medical Officer Anna Menon. Mission Commander Jared Isaacman has flown into space as the commander of Inspiration4.
Polaris Dawn is the first of three human spaceflight missions that are part of the Polaris program, which is designed to further the future of spaceflight, SpaceX said.

The objective of this Polaris Dawn spaceflight is to reach the highest Earth orbit ever flown since the Apollo program, officials noted. Additionally, the crew will participate in the first-ever extravehicular activity by commercial astronauts, who will be wearing extravehicular activity (EVA) suits developed by SpaceX.
Also, the team will conduct 35 research studies and experiments from 31 partner institutions, which SpaceX said are designed to further human health on Earth and on long-duration spaceflights. Plus, they will test Starlink's laser-based communications in space.
