Weather is one thing everyone has been keeping a close eye on ahead of NASA’s SpaceX Demo-2 launch to the International Space Station as part of the agency’s Commercial Crew Program. The first launch attempt on May 27 was rescheduled due to unfavorable weather conditions around Launch Complex 39A at NASA’s Kennedy Space Center in Florida. With the launch now targeted for 3:22 p.m. EDT tomorrow, May 30, NASA Administrator Jim Bridenstine remains hopeful for tomorrow’s launch, but stressed the importance protecting the test flight crew members, NASA astronauts Robert Behnken and Douglas Hurley.

“Our highest priority is and always has been Bob and Doug. And of course, a couple of days ago, we had too much electricity in the atmosphere,” said NASA Administrator Jim Bridenstine during a press briefing at Kennedy on May 29. “This is certain though: We are going to launch American astronauts on American rockets from American soil, and we will do it with the absolute priority being the safety of our astronauts.

“The president and vice president were proud of the NASA team and the SpaceX team for making the right call for the right reasons. When we do this again Saturday, if we do this again Sunday, we will feel no pressure. We will go when we are ready.”

The U.S. Air Force 45th Weather Squadron is predicting a 50% chance of favorable weather conditions for tomorrow’s launch, with the primary concerns for launch revolving around flight through precipitation, anvil and cumulus clouds.

NASA astronaut Kjell Lindgren, who flew on a Soyuz rocket in 2015, also participated in the press briefing, touching on his own experience with delayed launches.

“You certainly get excited about the launch; you’re prepared, your mindset is such that you’re ready to fly, and certainly Bob and Doug were ready to do that on Wednesday,” he said. “The scrub, the delay, just represents an opportunity for the team to learn and is an opportunity for them to reunite with their families. I know they’re spending time with their families and enjoying this little bit of time before they get ready to fly again.”

The SpaceX Falcon 9 rocket and Crew Dragon spacecraft will lift off from Kennedy’s Launch Complex 39A, carrying Behnken and Hurley to the space station to join astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner – the Expedition 63 crew members already onboard – making this the first launch of NASA astronauts from American soil in nearly a decade.

NASA’s Commercial Crew Program is working with partners SpaceX and Boeing to develop a U.S. commercial crew space transportation capability with the goal of achieving safe, reliable and cost-effective access to and from the space station and other destinations in low-Earth orbit.

“I can’t tell you what it’s going to mean to me to see a U.S. rocket launching crews again off that pad out there,” said Kennedy Space Center Director Bob Cabana. “We went to the Moon from that pad; I launched three times off that pad. To see Bob and Doug launch off it, and then to get Boeing launching, we are on the verge of a new era in human spaceflight. This is just the beginning; it’s only going to get better.”

NASA’s SpaceX Demo-2 will be the company’s final flight test, providing critical data on the performance of the Falcon 9 and Crew Dragon capsule, as well as the ground systems at the launch pad that will be supporting the launch. NASA and SpaceX teams will review data from all stages of launch, from liftoff to in-orbit, docking and landing operations – all paving the way for the agency to certify the crew transportation system for regular, crewed flights to the orbiting laboratory.

“What Elon Musk has done for the American space program is, he has brought vision and inspiration that we hadn’t had since the retirement of the space shuttles,” said Bridenstine. “When I talk to him, when I meet with him, he gives me a commitment and he delivers on that commitment. That has happened every single time.”

“We started out as a partnership, and in many respects, it’s become a friendship,” added NASA Deputy Administrator Jim Morhard.

Starting at 11 a.m. on Saturday, May 30, NASA and SpaceX will provide coverage of launch activities, airing on NASA TV and the agency’s website. This will include live shots of Behnken and Hurley as they put on their spacesuits, their arrival at historic Launch Complex 39A and liftoff of the Falcon 9 rocket. Coverage will continue through Crew Dragon’s docking to the space station, scheduled for 10:29 a.m. EDT on Sunday, May 31.

NASA’s SpaceX Demo-2 mission passed its final major review today at the agency’s Kennedy Space Center in Florida, and teams received the “go” to proceed toward launch. Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft, carrying NASA astronauts Robert Behnken and Douglas Hurley, is scheduled for Wednesday, May 27, at 4:33 p.m. EDT from Kennedy’s Launch Complex 39A.

The mission will return human spaceflight to the International Space Station from U.S. soil on an American rocket and spacecraft as a part of NASA’s Commercial Crew Program. Demo-2 will be SpaceX’s final test flight to validate its crew transportation system, including the Crew Dragon, Falcon 9, launch pad and operations capabilities.

“We’re burning down the final paper. All the teams are a go, and we’re continuing to progress toward our mission,” said Kathy Lueders, manager, NASA Commercial Crew Program. “I’m very proud of the team. We are continuing to be vigilant and careful, and make sure we do this right.”

In this morning’s official forecast, the U.S. Air Force 45th Weather Squadron predicted a 60% chance of unfavorable weather conditions for the Demo-2 mission. The primary weather concerns that could prevent launch are flight through precipitation, thick and cumulus clouds.

However, 45th Weather Squadron Launch Weather Officer Mike McAleenan pointed out things are looking up.

“It certainly has been trending better over the last day or two for launch weather,” McAleenan said. “If I was to issue the forecast today, right now, we would probably be down to 40% chance of violation.”

Crew members Behnken and Hurley remain in quarantine, a routine part of prelaunch preparations for astronauts journeying into space. On Saturday, they took part in a full dress rehearsal of launch day, including suiting up and climbing aboard the Crew Dragon at Launch Complex 39A.

“It was a really good review today, and from a crew perspective, we were very happy with the discussions that took place — the thoroughness of the review,” said Norm Knight, deputy director, Flight Operations, NASA Johnson Space Center. “We’re definitely ready to press forward.”

Upon arriving at the space station, Behnken and Hurley will join the Expedition 63 crew to conduct important research as well as support station operations and maintenance. While docked to the station, the crew will run tests to ensure the Crew Dragon spacecraft is capable on future missions of remaining connected to the station for up to 210 days.

“I think the on-orbit crew is definitely ready for some company, and very much looking forward to the launch this Wednesday,” said Kirk Shireman, manager, NASA International Space Station Program. “The ISS team is ready to support the docking of Crew Dragon.”

The specific duration for this mission will be determined after arrival based on the readiness of the next commercial crew launch. Finally, the mission will conclude with the Crew Dragon undocking from the station, deorbiting and returning Behnken and Hurley to Earth with a safe splashdown in the Atlantic Ocean.

Today at NASA’s Kennedy Space Center in Florida, NASA astronauts Robert Behnken and Douglas Hurley participated in a countdown dress rehearsal of the launch day events. The crewmates are preparing to launch aboard a SpaceX Crew Dragon spacecraft on the company’s Falcon 9 rocket and fly to the International Space Station. Demo-2 will be the first crewed mission for the agency’s Commercial Crew Program.

Behnken and Hurley began their day in the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building. The pair put on their black-and-white SpaceX spacesuits, took the elevator down to the ground level and exited through a pair of double doors, where their transport vehicle – a Tesla Model X — waited. With smiles and waves, they climbed in for the 20-minute ride to Launch Complex 39A.

The Falcon 9 rocket and Crew Dragon spacecraft have been in place on the launch pad since Thursday morning, May 21. Behnken and Hurley entered the Crew Dragon by way of the pad’s Crew Access Arm and checked their communications systems before the hatch was closed. The rehearsal concluded with the go/no-go poll for Falcon 9 propellant loading, which normally occurs 45 minutes before launch.

A strong high pressure ridge near Bermuda is creating east winds across Central Florida today. This flow may create morning coastal showers, but the cells will be inland of the Spaceport by the time they can develop into thunderstorms.  A low pressure area moving off the mid-Atlantic states stalls as it nudges into the ridge. Tomorrow, the low pressure area will weaken the ridge enough to allow an increase in moisture along its western periphery and into South Florida. Monday will see the clouds infiltrate the Space Coast as the ridge fully breaks down. Easterly winds will increase as a low pressure area develops over the Gulf of Mexico. Rain showers will be prevalent off and on all day. Tuesday will continue the cloudy, rainy conditions over the Spaceport. On launch day, continued extensive cloudiness is expected with rain showers and isolated thunderstorms expected throughout the day.
