SpaceX plans to reuse the Cargo Dragons up to five times. The Cargo Dragon will launch withoutSuperDraco abort engines, without seats, cockpit controls and the life support system required to sustain astronauts in space.[4][5]Dragon 2 improves onDragon 1 in several ways, including lessened refurbishment time, leading to shorter periods between flights.[6]
The new Cargo Dragon capsules under the NASA CRS Phase 2 contract will land east ofFlorida in the Atlantic Ocean.[4][6]
NASA contracted for the CRS-27 mission from SpaceX and therefore determines the primary payload, date of launch, andorbital parameters for theCargo Dragon.[7]

Various experiments were transported to the orbiting laboratory, and provided valuable insight for researchers. These include student projects that were given the opportunity to fly and operate their experiments on the ISS as part of DLR'sÜberflieger 2 competition. Among them are the projects:
FARGO (FerrofluidApplicationResearchGoesOrbital) of the Small Satellite Student Society of the University of Stuttgart (KSat e.V.)
ADDONISS (Ageing andDegenerativeDiseases ofNeurons on theISS)
European Space Agency (ESA) research and activities:[11]
ESA'sBIOFILMS (BiofilmInhibitionOnFlight equipment and on board theISS using microbiologicallyLethalMetalSurfaces) experiment investigating bacterial biofilm formation and antimicrobial properties of different metal surfaces under spaceflight conditions in altered gravity.
Vitrimeric reversible adhesive for in-space assembly
Mouse Habitat Unit-8 (MHU-8)mission - The NASA-JAXA Joint Partial-gravity Rodent Research Mouse Habitat Unit-8 (JPG-RR MHU-8) mission tested the impact of spaceflight and induced partial gravities on mice. The gravities tested were 0, 0.33, 0.66, 1 g. An interdisciplinary team of investigators will study how multiple biological systems (bone, muscle, cardiovascular system, neuro-performance, circadian rhythms, and microbiome) respond to these conditions.[13]
TheNEUtronDOSimetry &Exploration (NEUDOSE) mission from the McMaster Interdisciplinary Satellite Team[15] aims to further our understanding of long-term exposure to space radiation by investigating how charged and neutral particles contribute to the human equivalent dose during low-Earth orbit (LEO) missions. NEUDOSE is a 2U CubeSat built by students atMcMaster University. The scientific goals[16][17] of the project are to:
Demonstrate the Charged & Neutral Particle Tissue Equivalent Proportional Counter (CNP-TEPC) instrument, that allows for the discrimination of dose from charged and neutral particles in real-time.
Map the contribution of charged and neutral particle dose rates in LEO.
Themission objectives also include providing early-career science and engineering students with valuable leadership, technical, and flight project development skills.[14] Furthermore, the NEUDOSE mission is involved with the development ofamateur radio operators and custom hardware.[18]
Ex-Alta 2: A 3U CubeSat built by students from the University of Alberta's student organizationAlbertaSat. Ex-Alta 2's primary mission is to obtain scientific data forwildfire research and prevention. Additionally, Ex-Alta 2 was designed to promote the long-term goal of a fully open-sourced cube satellite, and the development of theAlbertan commercial space industry.[20]
AuroraSAT andYukonSat: 2U CubeSats built by students from the Aurora Research Institute and Yukon University in collaboration with the University of Alberta, who provided the bus for each cubesat and did final integration of payloads. One of the two primary missions is theNorthern Images Mission, which will display art on a small screen on the satellite, and then take images of this art from space with theEarth in the background. Children acrossNorthern Canada will have the opportunity to have their artwork featured. The Northern Voices Mission will transmit and broadcast recordings of Northern Canadian stories and perspectives inamateur radio bands across the world.[21]
This new iteration of theELaNa (Educational Launch of Nanosatellites) initiative will consist of two cubesats from American education institutes:
ARKSat-1: 1U CubeSat developed by students at theUniversity of Arkansas, its main mission will be to perform atmospheric measurements through the ground detection of a LED signal from orbit. Furthermore after the end of the mission the cubesat will make use of a Solid State Inflatable Balloon (SSIB) to increase the spacecraft's drag and speed up its re-entry.
LightCube: 1U CubeSat developed by students at theArizona State University, it carries a flash bulb that can be remotely activated by radio amateurs to produce a brief flash visible from the ground.
