This sparkling burst of stars is Messier 75. It is a globular cluster: a spherical collection of stars bound together by gravity. Clusters like this orbit around galaxies and typically reside in their outer and less-crowded areas, gathering to form dense communities in the galactic suburbs.

Vein scans and eye checks were on the schedule today as the Expedition 59 crew continues ongoing biomedical studies. The International Space Station is also getting ready to host a sixth spacecraft when it arrives next week.
Scientists have been observing the space residents all week as they seek to understand the effects of the upward flow of body fluids in space. Flight Engineer Anne McClain worked on the Fluid Shifts experiment again today attaching body electrodes to NASA astronaut Nick Hague and conducting ultrasound scans of his veins. She also peered into his eyes using optical tomography coherence hardware. Results may help flight surgeons prevent the increased head and eye pressure caused by the upward fluid shifts astronauts report in space.
NASA is also learning how to support longer human missions farther out into space. Feeding crews without expensive cargo missions and fuel-consuming inventories is critical. As a result, the station provides a variety of greenhouse facilities for plant cultivation and research. Christina Koch of NASA set up new botany hardware today to enable the ongoing research and harvesting of lettuce and mizuna in space.
The SpaceX Dragon resupply ship is due to liftoff Tuesday at 4:21 a.m. EDT on its 17th contracted cargo mission to the station. Canadian Space Agency astronaut David Saint-Jacques is training to capture Dragon with the Canadarm2 robotic arm when it arrives Thursday May 2 at 6:50 a.m. A pair of new experiments it is delivering will explore atmospheric carbon dioxide as well as X-ray frequency communication techniques.

The station will be operated from the Royal Thai Navy aircraft carrier, the Chakri Narubet, in the Gulf of Thailand from May 3-6 using the callsign HS10KING/mm.
This station will be making QSOs in the 40, 20, 15 and 10 metre HF bands, on 2 metres VHF and also using amateur radio satellites, including the Es’hail-2 / QO-100 satellite.
