Following a prelaunch news conference at NASA’s Kennedy Space Center in Florida, NASA and SpaceX remain “go” for tomorrow’s launch of SpaceX’s 21st Commercial Resupply Services mission to the International Space Station.

CRS-21 logo“This morning, we did a mission management team meeting, and we had a unanimous go for this launch and docking,” said Kenny Todd, deputy program manager of NASA’s International Space Station Program Office. “We’re excited to get on with it; we’ll see how things play out over the next couple of days, but hopefully by the middle of the week, we’ll have a Dragon on the way, if not already attached (to station).”

SpaceX’s Falcon 9 rocket, with the upgraded cargo Dragon spacecraft atop, stands poised for launch at Kennedy’s Launch Complex 39A, and weather officials are now predicting a 50% chance of favorable weather conditions for liftoff. While that’s a slight increase over previous launch forecasts, a cold front moving across the state of Florida will have teams keeping a close eye on the weather.

“Previously, it looked like that cold front would be passing right during the launch window, but the trend is now our friend – the models are now bringing that cold front through prior to the launch window,” said Melody Lovin, U.S. Space Force launch and weather officer for the 45th Space Wing.

“Because of that, we’re expecting most of the rain associated with the cold front to be pretty much done before the launch window opens up. We’re not exactly sure when the clouds are going to clear out of the way for us. We’re hoping the earlier the cold front will pass, the more clearing we’ll get.”

The first mission for SpaceX under NASA’s second Commercial Resupply Services contract, CRS-21 will deliver more than 6,400 pounds of supplies, equipment, and critical materials needed to support a variety of science and research investigations that will occur during Expeditions 64 and 65. With SpaceX’s Crew Dragon carrying a crew of four to the orbiting laboratory last month, the mission will also mark the first time two Dragon spacecraft will be attached to the space station simultaneously.

“It really ushers in a season of continuous Dragon presence for the near future,” said Sarah Walker, director of SpaceX Dragon Mission Management. “We’re excited about all of the missions that we’ll be flying for NASA and the International Space Station program, both cargo and crew, and it’s really just an honor to be a part of that.”

Dragon will spend about one month attached to the orbiting laboratory before autonomously undocking and returning to Earth with 5,200 pounds research and return cargo. The spacecraft is slated to splash down in the Atlantic Ocean upon its arrival.

Liftoff is targeted for 11:39 a.m. EST tomorrow, Dec. 5, with live launch countdown coverage beginning at 11:15 a.m. EST. Follow along here on the blog, NASA TV, or the agency’s website.

It was a picture perfect launch during a beautiful evening on Florida’s Space Coast, as NASA astronauts Michael HopkinsVictor Glover, and Shannon Walker, and Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) blasted off from Kennedy Space Center on NASA’s SpaceX Crew-1 mission.

“This is a great day for the United States of America and a great day for Japan,” said NASA Administrator Jim Bridenstine. “We look forward to many more years of a great partnership — not just in low-Earth orbit but all the way to the Moon.”

After lifting off from Kennedy’s Launch Complex 39A at 7:27 p.m., aboard SpaceX’s Crew Dragon spacecraft and the company’s Falcon 9 rocket, crew members are now a few hours into their 27.5-hour trip to the International Space Station for a six-month science mission.

“Everybody is so fired up; they’re so excited about this mission. But we’re not done yet; we need to keep going,” said Kathy Lueders, associate administrator for Human Exploration and Operations, NASA Headquarters. “That spacecraft is out there with those four precious crew members on it. And we’re going to get them safely to the International Space Station tomorrow.”

Crew-1 is the first crew rotation flight of a U.S. commercial spacecraft with astronauts to the space station following the spacecraft system’s official human rating certification. Hopkins, Glover, Walker, and Noguchi will join the Expedition 64 crew of Commander Sergey Ryzhikov, and Flight Engineers Sergey Kud-Sverchkov and NASA astronaut Kate Rubins. The arrival of Crew-1 will increase the regular crew size of the space station’s expedition missions from six to seven astronauts, adding to the amount of crew time available for research.

Tune in to NASA Television or the agency’s website for continuous comprehensive coverage of the Crew-1 mission, including docking at the space station on Monday, Nov. 16, at approximately 11 p.m. EST.

A welcome ceremony with Lueders and JAXA President Hiroshi Yamakawa will take place Tuesday, Nov. 17, at approximately 1:40 a.m. EST. That will be followed by a post-docking news conference at approximately 2 a.m., with:

  • Kathy Lueders, associate administrator for Human Exploration and Operations, NASA Headquarters
  • Mark Geyer, director of NASA’s Johnson Space Center in Houston
  • Ven Feng, deputy manager, Commercial Crew Program, Johnson
  • Joel Montalbano, manager, International Space Station, Johnson

Today at NASA’s Kennedy Space Center in Florida, NASA astronauts Michael Hopkins, Victor Glover, and Shannon Walker, and astronaut Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) participated in a countdown dress rehearsal of  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 for a six-month science mission.

NASA’s SpaceX Crew-1 astronauts began their day in the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building. They 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 vehicles — Tesla Model X cars — 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 Monday evening, Nov. 9. Crew Dragon Commander Hopkins, Pilot Glover, and Mission Specialists Walker and Noguchi 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.

Crew-1 is the first crew rotation flight of a U.S. commercial spacecraft with astronauts to the space station following the spacecraft system’s official human rating certification. Liftoff is slated for Saturday, Nov. 14, at 7:49 p.m. EST.

SpaceX Crew-1: Weather 70% Favorable, Crew Dry Dress Rehearsal Today

Today at NASA’s Kennedy Space Center, astronauts Michael Hopkins, Victor Glover, and Shannon Walker of NASA, and astronaut Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA) will participate in a countdown dress rehearsal of the launch day events for the first crew rotation flight of a U.S. commercial spacecraft with astronauts to the International Space Station.

NASA’s SpaceX Crew-1 mission is targeting launch at 7:49 p.m. EST Saturday, Nov. 14, from Launch Complex 39A at Kennedy. The four crew members will arrive at the space station for docking a short time later at 4:20 a.m. on Sunday morning to join Expedition 64 for a six-month science mission.

The U.S. Air Force 45th Weather Squadron now predicts a 70% chance of favorable weather conditions at the launch pad for lift off of NASA’s SpaceX Crew-1 mission based on Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns for the launch area will be cumulus clouds and flight through precipitation associated with Tropical Storm Eta.

Teams also will monitor weather conditions both for the launch area and downrange.
