The Worldwide House Station has acquired one other cargo supply, important for holding the Station’s seven-person crew equipped with experiments, consumables, and gear throughout its operation in low Earth orbit. This mission, CRS-27, launched on Tuesday, March 14 at 8:30 PM EDT (00:30 UTC on Wednesday, March 15) from LC-39A on the Kennedy House Middle. It docked on Thursday morning, 35 hours after launch.
This launch used first stage booster B1073, making its seventh flight. Earlier than CRS-27, B1073 began its profession in Could 2022 with the Starlink 4-15 mission. This booster has additionally flown the SES-22, Starlink 4-26, Starlink 4-35, Hakuto-R Mission 1, and Amazonas Nexus missions – all from Florida. Someday after the CRS-27 flight, the booster can be transformed right into a Falcon Heavy facet booster for the EchoStar-24 mission later this yr.
CRS-27, the sixteenth Falcon 9 and seventeenth total SpaceX mission of 2023, had an instantaneous launch window to fly northeast at a 51.6-degree inclination to the equator. After lofting Dragon and the second stage partway to orbit, the booster landed downrange on the drone ship A Shortfall of Gravitas positioned within the Atlantic Ocean.
The spacecraft reached the Station on Thursday and can dock on the PMA-2 port, not too long ago vacated by Crew Dragon Endurance. The docking occurred after over a 35-hour lengthy transit to the Station.
This mission makes use of Cargo Dragon C209 on its third flight. This mission happens after a 449-day turnaround from launching CRS-24 on Dec. 21, 2021. C209 made its first flight with the CRS-22 mission on June 3, 2021.

This aligns with the coverage of now reusing Cargo and Crew Dragon spacecraft. Every Dragon, minus the precise warmth defend – which isn’t but reused – is at present rated for use for as much as 5 flights, however this might change sooner or later.
The Cargo Dragon is loaded with a number of metric tons of experiments, CubeSats, important provides, and different cargo. This contains greater than 15 experiments sponsored by the ISS Nationwide Laboratory, together with the ultimate two experiments within the Tissue Chips in House initiative.
A JAXA astrobiology experiment can be flying on CRS-27. Tanpopo-5 will research how varied microbes, sporophytes, amino acids, peptides, and nucleotide precursors fare throughout publicity to the house surroundings.

Experiments involving engineered coronary heart tissues, 3D-printed RF circuits, the MAPT-I radiation detector, photonic built-in circuits, biotherapeutic compounds crystallization, foam, emulsions construction, and different areas of research can be flown on CRS-27.
One other notable payload on this flight is a ball clamp monopod – manufactured by college students – that may simplify filming in house. Nonetheless, this isn’t the one payload on CRS-27 that college students have been concerned in. Experiments from Canadian and German universities are additionally onboard. 4 Canadian CubeSats – Ex-Alta 2, AuroraSat, YukonSat, and NEUDOSE – are flying on Dragon, together with the College of Stuttgart’s FARGO ferrofluid experiment.
NASA’s ELaNa (Academic Launch of Nanosatellites) 50 mission will fly a pair of CubeSats aboard CRS-27. ARKSAT-1, developed by the College of Arkansas, is a 1U CubeSat that’s geared up with an LED mild. This mild can be activated, and a spectrometer on the bottom will conduct orbit-to-ground atmospheric measurements by monitoring the sunshine.
ARKSAT-1 may even try and deorbit itself on the finish of its mission with a Strong State Inflation Balloon (SSIB). Inflating the SSIB will improve the atmospheric drag on the satellite tv for pc, inflicting it to deorbit ahead of it in any other case would. If this know-how works, it may be used to deorbit CubeSats on the finish of their helpful lives, stopping further “house junk” from cluttering low Earth orbit.
One other 1U CubeSat that’s a part of ELaNa 50 is LightCube, a cooperative effort between Arizona State College, CETYS Universidad in Mexico, and Vega House Methods. Like ARKSAT-1, LightCube could have a robust mild as its most important payload. On this case, LightCube is supplied with a flashbulb that may be managed by newbie radio operators.

The operators can activate a flash that can make the satellite tv for pc as vivid because the Worldwide House Station for a quick time frame. The builders of LightCube hope to encourage its customers to study satellites and house ideas, by way of the customers with the ability to situation a command and see a tangible end result within the night time sky.
As well as, the US House Drive is flying the STP-H9 exterior payload on this mission with eight experiments on board. STP-H9 can be mounted on the Japanese Kibo module’s Uncovered Facility as an exterior payload, and its experiments will check out applied sciences that might be used on future USSF missions.
CRS-27 will stay on the Station for round a month earlier than coming again to Earth with experiment outcomes, samples, and different cargo, benefiting from Dragon’s sizable downmass functionality. CRS-27 will make the most of the identical splashdown websites and restoration infrastructure used on all different Crew and Cargo Dragon flights.
Cargo Dragon 2 is at present the one spacecraft serving the ISS that may return important quantities of cargo to Earth at the moment. Nonetheless, further programs with return functionality just like the Sierra House Dream Chaser and the Russian Soyuz GVK are in improvement.
