While SpaceX’s next crew mission awaits a launch opportunity just up the coast, another Falcon 9 rocket is poised for liftoff from Cape Canaveral Thursday with another cluster of 53 Starlink internet satellites heading for a deployment orbit nearly 200 miles above Earth.
Within Jupiter’s massive system of satellites, four large moons really stand out. They’re known as the “Galilean Moons” in honor of Galileo Galilee, who made the first recorded observations of them in 1610. The innermost of these moons is the rocky moon Io, which is slightly larger than Earth’s Moon and slightly denser. With more than 400 active volcanoes on its surface, it is the most geologically active body in the Solar System.
Imagine standing on Mars, and seeing this with your own eyes.

The launch of a SpaceX Falcon 9 rocket carrying the next astronaut crew to the International Space Station has been postponed from Saturday after weather delays in returning a team of commercial astronauts from the outpost back to Earth, NASA officials said Wednesday.
The tiny Mars moon Phobos looms large on the sun's face in dramatic eclipse footage captured by NASA's Perseverance rover.
In 1930, astronomer Clyde Tombaugh discovered the fabled “Ninth Planet” (or “Planet X”) while working at the Lowell Observatory in Flagstaff, Arizona. The existence of this body had been predicted previously based on perturbations in the orbit of Uranus and Neptune. After receiving more than 1,000 suggestions from around the world, and a debate among the Observatory’s staff, this newfound object was named Pluto – which was proposed by a young schoolgirl from Oxford (Venetia Burney).
Since its first crewed flight in 2020, SpaceX has continued to launch astronauts to the International Space Station and return them home to Earth as part of a partnership with NASA.

A Ukrainian space tech start-up has postponed its goal of going to the moon to volunteer its technology to fight Russia. But they still believe they will get there one day.
Two immense swarms of sunspots have popped into view on the surface of the sun, hinting at the increased possibilities of vivid auroras and potentially damaging solar flares over the months to come.
Astronomers have observed and identified a new type of thermonuclear stellar explosion — a micronova. It's a million times less powerful than a standard nova and lasts just a few hours.
Some of the proceeds will benefit the Planetary Society, adding to a years-long collaboration involving the nonprofit's CEO, Bill Nye.
The test version of a unique satellite navigation receiver has been delivered for integration testing on the Lunar Pathfinder spacecraft. The NaviMoon satnav receiver is designed to perform the farthest ever positioning fix from Earth, employing signals that will be millions of times fainter than those used by our smartphones or cars.
SpaceX rolled a reused Falcon 9 booster and a brand new Dragon crew capsule to their launch pad Tuesday at the Kennedy Space Center in Florida for final tests, a day after the astronauts who will ride the spacecraft to the space station arrived for pre-flight preparations.
