While SpaceX continues preparations for the launch of NASA’s SpaceX Crew-1 mission to the International Space Station as part of the Commercial Crew Program, the company also is getting ready for the agency’s next cargo resupply mission to the orbiting laboratory.

SpaceX’s 21st resupply mission for NASA, its first under the second-generation Commercial Resupply Services (CRS-2) contract, will be the first resupply mission to use the upgraded version of the Dragon spacecraft. The flight will bring science and supplies to the newly expanded Expedition 64 crew beginning with liftoff on the SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

NASA and SpaceX currently are targeting no earlier than 12:50 p.m. ET on Wednesday, Dec. 2, for the CRS-21 launch, pending Eastern Range acceptance and successful preparations and an on-time liftoff of Crew-1, also from Launch Complex 39A.

The science to be delivered on this mission includes a study aimed at better understanding heart disease to support development of treatments for patients on Earth, research into how microbes can be used for biomining on asteroids, and a tool being tested for quick and accurate blood analysis in microgravity. The first commercially owned and operated airlock on the space station, the Nanoracks Bishop Airlock, will arrive in the unpressurized trunk of the Dragon spacecraft. Bishop will provide a variety of capabilities to the orbiting laboratory, including CubeSat deployment and support of external payloads.

Dream Chaser® Spaceplane Pressure Test Article Arrives at Kennedy Space Center

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.

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.

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.

Weather Forecast Favorable for SpaceX CRS-20 Launch

The SpaceX Falcon 9 rocket with the Dragon cargo module lifts off Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida on Dec. 5, 2019, at 12:29 p.m. EST. It was SpaceX’s 19th Commercial Resupply Services (CRS-19) mission for NASA to the International 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 CRS-20 Launch Targeted for March 6

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.
