SpaceX Crew-8 is the eighth crewed operational NASA Commercial Crew flight and the 13th overall crewed orbital flight of a Crew Dragon spacecraft. The mission launched on 4 March 2024.
The Crew-8 mission transports four crew members to the International Space Station (ISS). Three NASA astronauts, Matthew Dominick, Michael Barratt, and Jeanette Epps, and one Roscosmos cosmonaut, Alexander Grebenkin, were assigned to the mission. Jeanette Epps was previously assigned to Boeing Starliner missions.
Messier 74 is a spiral galaxy like our Milky Way, which is seen face-on from Earth’s vantage point some 32 million light-years away. X-rays from Chandra (purple) have been combined with an infrared view of M74 from NASA’s James Webb Space Telescope (green, yellow, red, and magenta) as well as optical data from NASA’s Hubble Space Telescope (orange, cyan, and blue). In sonifying these data, a clockwise-moving radar-like scan starts around 12 o’clock. The distance from the center controls the frequencies of sound with light farther from the center being higher pitched. The Chandra sources correspond to relatively high musical pitches of glassy ethereal and clear plucked sounds. In the Webb data, large, medium, and small features are represented by low, medium, and high frequency ranges of pitches respectively with the brightest stars being heard as percussive sounds. The Hubble data have been turned into breathy synthesizer sounds along with thin metallic plucked sounds for bright stars and clusters.
Europa Clipper (previously known as Europa Multiple Flyby Mission) is a space probe in development by NASA. Planned for launch in October 2024, the spacecraft is being developed to study the Galilean moon Europa through a series of flybys while in orbit around Jupiter.
This mission is a scheduled flight of the Planetary Science Division, designated a Large Strategic Science Mission, and funded under the Planetary Missions Program Office’s Solar System Exploration program as its second flight. It is also supported by the new Ocean Worlds Exploration Program. Europa Clipper will perform follow-up studies to those made by the Galileo spacecraft during its eight years (1995 – 2003) in Jupiter orbit, which indicated the existence of a subsurface ocean underneath Europa’s ice crust. Plans to send a spacecraft to Europa were initially conceived with projects such as Europa Orbiter and Jupiter Icy Moons Orbiter, in which a spacecraft would be injected into orbit around Europa. However, due to the adverse effects of radiation from Jupiter’s magnetosphere in Europa orbit, it was decided that it would be safer to inject a spacecraft into an elliptical orbit around Jupiter and make 44 close flybys of the moon instead. The mission began as a joint investigation between the Jet Propulsion Laboratory (JPL) and the Applied Physics Laboratory (APL), and will be built with a scientific payload of nine instruments contributed by JPL, APL, Southwest Research Institute, University of Texas at Austin, Arizona State University and University of Colorado Boulder. The upcoming mission complements ESA’s Jupiter Icy Moons Explorer launch in 2023, which will fly-by Europa twice and Callisto multiple times before moving into orbit around Ganymede.
The mission is scheduled to launch in October 2024 aboard a Falcon Heavy, during a 21-day launch window. The spacecraft will use gravity assists from Mars in February 2025 and Earth in December 2026, before arriving at Europa in April 2030.
