SpaceX plans to reuse the Cargo Dragons up to five times. The Cargo Dragon will launch without
SuperDraco abort engines, without seats, cockpit controls and the life support system required to sustain astronauts in space.[4][5]Dragon 2 improves on
Dragon 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 of
Florida in the Atlantic Ocean.[4][6]
Payload
NASA contracted for the CRS-27 mission from SpaceX and therefore determines the primary payload, date of launch, and
orbital parameters for the
Cargo Dragon.[7]
SWELL (Space Wireless Energy Laser Link), a test payload for laser power beaming.[10]
Electric Propulsion Electrostatic Analyzer, A test device that will demonstrate re-boost using
ion propulsion.
Neutron Radiation Detection Instrument from NRL
Variable Voltage Ion Protection Experiment from NRL
ECLIPSE (Experiment for Characterizing the Lower Ionosphere and Production of Sporadic-E)
Glowbug, cosmic ray detector built in conjunction with NASA, an experiment that will study cosmic rays for two years.
SpaceCube Edge Node Intelligent Collaboration, an experiment built by
NASA Goddard that will study microchips and artificial intelligence exposed to the vacuum of space.
SOHIP, a hyperspectral imager built by
Livermore Labs that will study the atmosphere for two years.
Research
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's
Überflieger 2 competition. Among them are the projects:
FARGO (Ferrofluid Application Research Goes Orbital) of the Small Satellite Student Society of the University of Stuttgart (
KSat e.V.)
BRAINS (Biological Research using Artificial Intelligence for Neuroscience in Space)
ADDONISS (Ageing and Degenerative Diseases of Neurons on the ISS)
European Space Agency (ESA) research and activities:[11]
ESA's
BIOFILMS (Biofilm Inhibition On Flight equipment and on board the ISS using microbiologically Lethal Metal Surfaces) 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]
The NEUtron DOSimetry & 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 at
McMaster 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.
The
mission 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 of
amateur radio operators and custom hardware.[18]
Ex-Alta 2: A 3U CubeSat built by students from the University of Alberta's student organization
AlbertaSat. Ex-Alta 2's primary mission is to obtain scientific data for
wildfire 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 the
Albertan commercial space industry.[20]
AuroraSAT and
YukonSat: 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 the
Northern Images Mission, which will display art on a small screen on the satellite, and then take images of this art from space with the
Earth in the background. Children across
Northern 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 in
amateur radio bands across the world.[21]
This new iteration of the
ELaNa (Educational Launch of Nanosatellites) initiative will consist of two cubesats from American education institutes:
ARKSat-1: 1U CubeSat developed by students at the
University 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 the
Arizona State University, it carries a flash bulb that can be remotely activated by radio amateurs to produce a brief flash visible from the ground.
