SpaceX launches the SpX-27 to the ISS

Freighter will dock at the International Space Station tomorrow

Rocket takes off from platform 39A

SpaceX's reusable cargo spacecraft, Cargo Dragon C209, launched to the International Space Station (ISS) on Tuesday, March 14, 2023 at 8:30 pm Eastern Time. The launch used Falcon 9 v1.2 BL 5 rocket number B1073.7 as part of the CRS-27 mission was carried out from Launch Complex 39A at Cape Canaveral in Florida. The spacecraft was placed into an orbit with an apogee of 208 km, a perigee of 194 km, a period of 88.51 minutes and inclined 51.64 degrees. The docking is scheduled for tomorrow, the 16th, at 7:52 am EDT, in the PMA-2 coupling compartment in the nose of the American module Harmony.

After separation, the first stage of Falcon 9 B1073 landed on the drone raft A Shortfall of Gravitas in the Atlantic Ocean, 668 km from the coast, alongside the support vessel Doug.

This is SpaceX's seventh flight to the ISS in the modified Cargo Dragon 2, which is capable of delivering 20% ​​more cargo and can also dock autonomously without the help of grabbing it with a manipulator arm compared to the first V1 version. . The new reusable craft are designed for five round-trip flights to the ISS instead of three as part of previous Dragon freighter missions. They can remain at the station for 75 days, against 40 days in the previous option. From October 2012 to December 2022, SpaceX performed 26 launches of Cargo Dragons to the ISS. One of them (in 2015) ended in failure due to the failure of the Falcon 9 launch vehicle.

The spacecraft will deliver more than three tons of supplies, equipment and materials for dozens of scientific experiments by its crew, and takes several cubesats to be ejected: STP-H9, ARKSAT 1 1U from the University of Arkansas Technology, LightCube 1U from Arizona State University, Ex -Alta 2 3U for thermospheric research from the University of Alberta, AuroraSat 2U from Aurora College, YukonSat 2U for thermospheric research from Yukon College, and the NEUDOSE 2U from McMaster University, these from Canada.

Payloads transported

The cargo (2,800 kg) transported includes projects from students who had the opportunity to carry out their experiments on the ISS as part of the DLR's Überflieger 2 competition and studies by NASA's Glenn Research Center. Among them are the Research projects:

Summary cargo manifest on spacecraft

FARGO (Ferrofluid Application Research Goes Orbital) from the Small Satellite Student Society of the University of Stuttgart (KSateV) BRAINS (Biological research using artificial intelligence for neuroscience in space)

ADDONISS (Aging and Degenerative Diseases of Neurons on the ISS)

Research and activities of the European Space Agency (ESA):

BIOFILMS (Biofilm Inhibition On Flight equipment and on the ISS using microbiologically Lethal Metal Surfaces) experiment that investigates the formation of bacterial biofilm and antimicrobial properties of different metallic surfaces under space flight conditions in altered gravity.

Cardinal Heart – The first Cardinal Heart experiment conducted aboard the space station showed that four weeks of exposure to microgravity can cause significant changes in heart cell function and gene expression. The researchers concluded that these changes can lead to long-term medical problems. The Cardinal Heart 2.0 experiment builds on these results, using heart organoids, 3D structures made up of all the different types of cells in a given organ, to test whether clinically approved drugs reduce these microgravity-induced changes in heart cell function. The results could support the development of effective drug combinations to improve the health of astronauts and patients on Earth.

Engineered Heart Tissues-2 – This study continues work with 3D-cultured heart muscle tissue to assess human heart function in microgravity. Previous work with 3D cultures in space has detected changes at the cellular and tissue level that could provide an early indication of the development of heart disease. This investigation tests whether new therapies prevent these adverse effects of spaceflight from occurring. The model used in this study has potential use in drug development and other applications related to the diagnosis and treatment of cardiac disorders on Earth.

Cardinal Heart 2.0 and Engineered Heart Tissues-2 are the latest two experiments to comprise the initiative of the National Institutes for Health and the ISS National Lab's Tissue Chips in Space. The researchers hope to learn more about the impact of microgravity on human health and disease and translate this understanding to improve human health.

HUNCH Ball Clamp Monopod – The NASA High School Students Unite with NASA to Create Equipment (HUNCH) program allows students to make real-world products for NASA while applying their skills in science, technology, engineering and math. The HUNCH Ball Clamp Monopod attempts to address astronauts' comments about the difficulty of positioning video or photo cameras in the middle of a module. The student-made design consists of an aluminum pedestal equipped with a camera shoe and a ball clamp that attaches to a standard space station handrail. The circular clamp serves as a turntable for photography and video.

CapiSorb Visible System – Because microgravity makes it difficult to control the flow of liquids, the space station has not been able to take advantage of carbon dioxide removal methods that use specialized liquids. Liquid-based carbon dioxide removal systems, such as those on submarines, offer greater efficiency than other types of systems. The CapiSorb Visible System study demonstrates liquid control using capillary forces, the interaction of a liquid with a solid that can pull a fluid through a narrow tube, characteristic of liquids that can absorb carbon dioxide. This is an important consideration for future long-duration space missions, where efficiency will support crews for many months or years.

Tanpopo-5 – The JAXA (Japan Aerospace Exploration Agency) Tanpopo-5 investigation studies the origin, transport and survival of life in space and on extraterrestrial planets such as Mars. The study focuses on exposing radioresistant bacteria, which are resistant to radiation, and moss sporophytes, an important part of the life cycle of some plants, to the harsh environment of space using the exposed experiment stand attached to the I-SEEP facility ( ExBAS). mounted on the outside of the station. The results are helping to answer key questions of the "panspermia" hypothesis, a theory for the beginning of life on Earth and the transport of life between celestial bodies.

CubeSats planned to launch on this mission:


The McMaster Interdisciplinary Satellite Team's NEUtron DOSimetry & Exploration (NEUDOSE) mission aims to deepen our understanding of long-term exposure to space radiation by investigating how charged and neutral particles contribute to the equivalent human dose during low Earth orbit (LEO) missions. NEUDOSE is a 2U CubeSat built by students at McMaster University. The project objectives are:

Demonstrate the Charged & Neutral Particle Tissue Equivalent Proportional Counter (CNP-TEPC) instrument, which allows the discrimination of the dose of charged and neutral particles in real time. Map the contribution of dose rates from charged and neutral particles in low orbit.
