Inside the Florida spaceport’s Rotation, Processing and Surge Facility, the NASA and Jacobs team completed a pin. The pinning activity involved using bolts to attach one of five segments that make up one of two solid rocket boosters for SLS to the rocket’s aft skirt. A crane crew assisted in mating the aft segments to the rocket’s two aft skirts.
A handful of the team members gained pinning experience on boosters for the space shuttle, while the rest were first-time pinners. Pablo Martinez, Jacobs TOSC handling, mechanical and structures engineer, inserted the first of 177 pins per joint to complete the first official step in stacking the SLS boosters.
Manufactured by Northrop Grumman in Utah, the 177-foot-tall twin boosters provide more than 75 percent of the total SLS thrust at launch. SLS is the most powerful rocket NASA has ever built.
The SLS rocket will launch NASA’s Orion spacecraft and send it to the Moon for Artemis I — a mission to test the two as an integrated system, leading up to human missions to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon by 2024.
Due to launch vehicle processing delays in preparation for spacecraft mate operations, NASA and United Launch Alliance have moved the first launch attempt of the Mars 2020 mission to no earlier than July 30. A liquid oxygen sensor line presented off-nominal data during the Wet Dress Rehearsal, and additional time is needed for the team to inspect and evaluate. Flight analysis teams have expanded the mission launch opportunities to August 15 and are examining if the launch period may be extended further into August.
NASA and United Launch Alliance are now targeting Wednesday, July 22, for launch of the Mars 2020 mission due to a processing delay encountered during encapsulation activities of the spacecraft. Additional time was needed to resolve a contamination concern in the ground support lines in NASA’s Payload Hazardous Servicing Facility (PHSF).
The spacecraft and vehicle remain healthy. The launch of the Mars 2020 mission on an Atlas V rocket from Space Launch Complex-41 on Cape Canaveral Air Force Station is scheduled for 9:35 a.m. ET with a two-hour window.
Continuing on its path to preparation for next month’s launch, NASA’s Mars Perseverance rover spacecraft is, well, put together.
Inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida, the Backshell-Powered Descent Vehicle and Entry Vehicle assemblies are now attached to Perseverance. The cone-shaped backshell contains the parachute, and along with the mission’s heat shield, will provide protection for the rover and descent stage during entry into the Martian atmosphere.
Recently, the rover’s ULA Atlas V booster was lifted up in the Vertical Integration Facility at Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) in Florida.
Activities have continued to ramp up with the attachment of the four solid rocket boosters (SRBs) one-by-one to the sides of the Atlas V 541 rocket, followed by the Centaur upper stage. The Centaur can control its orientation precisely, while providing up to 22,300 pounds of thrust. The spacecraft will be mated to the Atlas V rocket on June 22.
The assembly, test and launch operations team from NASA’s Jet Propulsion Laboratory and United Launch Alliance (ULA) engineers have hit multiple key milestones in the past two months, keeping Perseverance on target for its launch to the Red Planet in mid-July. These include attaching the aeroshell backshell and attaching the rover to its rocket-powered descent stage, rotating and spinning the descent stage on two separate measuring fixtures to pinpoint its center of gravity, and attaching NASA’s Mars Helicopter, recently named Ingenuity, to the belly of the rover.
Perseverance will reach Mars on Feb. 18, 2021, touching down on the surface of Jezero Crater. Developed under NASA’s Mars Exploration Program, the rover’s astrobiology mission will search for signs of past microbial life.
NASA Administrator Jim Bridenstine on Friday selected Commercial Crew Program Manager Kathy Lueders to be the agency’s next associate administrator of the Human Exploration and Operations (HEO) Mission Directorate. Since 2014, Lueders has directed NASA’s efforts to send astronauts to space on private spacecraft, which culminated in the successful launch of Demo-2 from the Kennedy Space Center in Florida on May 30.
Lueders began her NASA career in 1992 at the White Sands Test Facility in New Mexico where she was the Shuttle Orbital Maneuvering System and Reaction Control Systems Depot manager. She later moved to the International Space Station Program and served as transportation integration manager, where she led commercial cargo resupply services to the space station.
She also was responsible for NASA oversight of international partner spacecraft visiting the space station, including the European Space Agency’s Automated Transfer Vehicle, the Japan Aerospace Exploration Agency’s H-II Transfer Vehicle, and the Russian space agency Roscosmos’ Soyuz and Progress spacecraft. She went to Kennedy as acting Commercial Crew Program Manager in 2013 and was selected as the head of the office in 2014.
The appointment takes effect immediately. Steve Stich is named Commercial Crew Program Manager, and Ken Bowersox returns to his role as HEO deputy associate administrator.
Sierra Nevada Corporation’s (SNC) Dream Chaser pressure test article arrived at NASA’s Kennedy Space Center in Florida on June 3, 2020, from Louisville, Colorado, and was transported to the high bay in the Space Station Processing Facility.
The test article is similar to the actual pressurized cabin being used in the Dream Chaser spaceplane for Commercial Resupply Services-2 (CRS-2) missions. NASA selected Dream Chaser to provide cargo delivery, return and disposal service for the International Space Station under the CRS-2 contract.
Under the contract, Dream Chaser will provide a minimum of six cargo missions to and from the space station, carrying critical supplies like food, water and science experiments, and return to Earth with a landing at Kennedy’s Launch and Landing Facility, managed by Space Florida.
The pressure test article was used to validate that Dream Chaser can withstand the demands associated with repeated launches and returns from space. SNC designed the Dream Chaser spacecraft to be reusable for as many as 15 missions. The pressure article specifically verified the composite and bonded structure of the spacecraft.
The test article will remain at Kennedy while SNC engineers use it to develop and verify refurbishment operations that will be used on Dream Chaser between flights.
The SpaceX Falcon 9 rocket, carrying NASA astronauts Robert Behnken and Douglas Hurley aboard the company’s Crew Dragon spacecraft, lifted off from Kennedy Space Center’s historic Launch Pad 39A at 3:22 p.m. EDT.
Behnken and Hurley are on their way to the International Space Station, where they will become part of the Expedition 63 crew, joining astronaut Chris Cassidy and cosmonauts Ivan Vagner and Anatoly Ivanishin.
The Demo-2 mission is SpaceX’s final test flight for NASA’s Commercial Crew Program and will provide critical data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft and ground systems, as well as in-orbit, docking and landing operations.
Live coverage of NASA’s SpaceX Demo-2 launch activities has begun. The broadcast started at 11 a.m., and will continue leading up to liftoff and through arrival at the space station at 10:29 a.m. on Sunday, May 31. Watch it on NASA Television and online at http://www.nasa.gov/live.
A SpaceX Falcon 9 rocket and Crew Dragon spacecraft will lift off from Launch Pad 39A at Kennedy Space Center in Florida this afternoon, carrying American NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station. Launch is targeted for 3:22 p.m. EDT. The launch window is instantaneous.
According to the latest report from the 45th Weather Squadron at Patrick Air Force Base, the probability of violating weather restraints remains at 50%. Primary concerns are flight through precipitation, anvil cloud rule and cumulus cloud rule.
This will be SpaceX’s final test flight for NASA’s Commercial Crew Program and will provide critical data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft, and ground systems, as well as in-orbit, docking, and landing operations.
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.
