NASA commercial cargo provider SpaceX is targeting 11:50 p.m. EST tonight, March 6, for the launch of resupply mission to the space station.
A briefing about the science payloads for delivery on the SpaceX CRS-20 mission to the International Space Station is set for today at 3 p.m. Tune in to NASA Television. Participants include:
- Jennifer Buchli, deputy chief scientist for NASA’s International Space Station Program Science Office, who will share an overview of the research being conducted aboard the space station and how it benefits exploration and humanity.
- Michael Roberts, interim chief scientist for the International Space Station U.S. National Laboratory, who will discuss the lab’s work in advancing science in space, and in developing partnerships that drive industrialization through microgravity research.
- Bill Corely, director of business development for Airbus Defence and Space, and Bartolomeo Project Manager Andreas Schutte, who will discuss Bartolomeo, a new commercial research platform from ESA (European Space Agency), set to be installed on the exterior of the orbiting laboratory.
- Chunhui Xu, associate professor of Emory University School of Medicine, and principle investigator for the Generation of Cardiomyocytes from Induced Pluripotent Stem Cells (MVP Cell-03) experiment, who will discuss the study on the generation of specialized heart muscle cells for use in research and clinical applications.
- Paul Patton, senior manager, front end innovation and regulatory for Delta Faucet, and Garry Marty, principal product engineer for Delta Faucet, who will discuss the Droplet Formation Study, which evaluates water droplet formation and water flow of Delta Faucet’s H2Okinetic showerhead technology. This research in microgravity could help improve technology, creating better performance and improved user experience while conserving water and energy.
- Aaron Beeler, professor of medicinal chemistry at Boston University, and principal investigator, and co-investigator Matthew Mailloux of Flow Chemistry Platform for Synthetic Reactions on ISS, which will study the effects of microgravity on chemical reactions, as a first step toward on-demand chemical synthesis on the space station.
Meteorologists with the U.S. Air Force 45th Space Wing predict a 60 percent chance of favorable weather for liftoff of the SpaceX Falcon 9 rocket for the company’s 20th commercial resupply services mission to the International Space Station. Launch is scheduled for Friday, March 6 at 11:50 p.m. EST from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. Skies will clear through the day Friday, and winds will become gusty out of the north as a high-pressure area moves east. The primary weather concern for launch is liftoff winds with the tight pressure gradient behind the front.
SpaceX is now targeting March 6 at 11:50 p.m. EST for launch of its 20th commercial resupply services mission (CRS-20) to the International Space Station. During standard preflight inspections, SpaceX identified a valve motor on the second stage engine behaving not as expected and determined the safest and most expedient path to launch is to utilize the next second stage in line that was already at the Cape and ready for flight. The new second stage has already completed the same preflight inspections with all hardware behaving as expected. The updated target launch date provides the time required to complete preflight integration and final checkouts.
The cargo Dragon will lift off atop a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying more than 5,600 pounds of science investigations and cargo to the station, including research on particle foam manufacturing, water droplet formation, the human intestine and other cutting-edge investigations.
Critical supplies, equipment and material are on its way to the International Space Station following the successful launch of a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida. The company’s uncrewed Dragon spacecraft lifted off atop the Falcon 9 at 12:29 p.m. EST from Space Launch Complex 40 on Dec. 5, 2019, for the 19th Commercial Resupply Services (CRS-19) mission.
Dragon is scheduled to arrive at the space station Dec. 8, with live coverage on spacecraft rendezvous and capture beginning at 4:30 a.m. EST on NASA TV and the agency’s website. To read a full recap of the launch, click here.
This morning’s launch attempt has been scrubbed due to winds. The next launch opportunity will be at 12:29 p.m. EST on Thursday, Dec. 5. Launch coverage for the SpaceX CRS-19 mission to the International Space Station will begin at 12 p.m. EST on NASA Television, the agency’s website and the launch blog.
SpaceX’s 19th Commercial Resupply Services (CRS-19) mission is set to launch at 12:51 p.m. EST today from Cape Canaveral Air Force Station in Florida. The company’s uncrewed Dragon spacecraft – launching aboard a Falcon 9 rocket – will deliver research, supplies and equipment to the International Space Station.

A “Shooting Star” was unveiled Tuesday, Nov. 19, at Kennedy Space Center.
During a media event held in the Florida spaceport’s Space Station Processing Facility high bay, former NASA astronaut and current Senior Vice President of Strategy for Sierra Nevada Corporation (SNC) Space Systems Steve Lindsey revealed the name of the cargo module that will attach to the back of the company’s Dream Chaser spacecraft: Shooting Star.
“It’s an exciting day for us,” said Lindsey, a veteran of five NASA shuttle missions.
Shooting Star is a 15-foot-long cargo module that will attach to the back of the 30-foot-long Dream Chaser. It will be used to deliver more than 12,000 pounds of supplies and other cargo for NASA to the International Space Station as part of the Commercial Resupply Services-2 (CRS-2) contract. Its first flight is scheduled to launch from Kennedy in fall 2021.
“Sierra Nevada Corporation is excited to be expanding our footprint here at Kennedy Space Center,” said Kimberly Schwandt, senior communications manager for SNC Space Systems.
Dream Chaser will fly back to Earth and land on the runway at Kennedy’s Launch and Landing Facility, formerly the Shuttle Landing Facility. Shooting Star will have a different fate. It will carry unwanted cargo from the space station, disposing of it while burning up upon re-entry into Earth’s atmosphere. The process of “burning up” is where the Shooting Star name came from, Lindsey explained.
“The cargo module is really interesting because it’s kind of the unsung hero of the whole Dream Chaser cargo system design,” Lindsey said, while standing in front of a Shooting Star testing mockup. “It has a very unique shape — notice how it angles in as you go higher. It’s shaped to handle external and internal payloads.”
Payload capability includes pressurized and unpressurized cargo. Though it was designed specifically for cargo resupply services to the space station, Shooting Star can have many other applications, Lindsey said, including carrying crew, operating as a free-flying satellite and going from low-Earth to lunar orbit.
“It’s a pretty versatile system,” Lindsey said, “and the more we worked on it, the more we realized there are multiple applications for it.”
The Shooting Star mockup was recently delivered to Kennedy from SNC’s facility in Colorado. It will remain at the Florida spaceport, Lindsey said, for testing, processing and training of flight controllers.
NASA selected Dream Chaser for the CRS-2 contract, which involves launching six cargo missions to the space station by 2024.
At 6:01 p.m. EDT on July 25, 2019, SpaceX’s Falcon 9 rocket launched from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying the uncrewed Dragon spacecraft on the company’s 18th Commercial Resupply Services (CRS-18) mission.
Due to arrive at the International Space Station on July 27, the Dragon spacecraft contains multiple supplies, equipment and material critical for supporting science and research investigations at the space station.
