The space tourist crew who spent three days orbiting Earth in a SpaceX Dragon capsule has returned to our planet in one piece.…

Watch the video here! "SpaceX safely returned its Crew Dragon spacecraft from orbit on Saturday, with the capsule carrying the four members of the Inspiration4 mission back to Earth after three days in space..." reports CNBC: "Thanks so much SpaceX, that was a heck of a ride for us and we're just getting started!" Inspiration4 commander Jared Isaacman said from the capsule after touching down. Elon Musk tweeted his congratulations to the crew shortly after splashdown. The historic private mission — which includes Isaacman, pilot Sian Proctor, medical officer Hayley Arceneaux and mission specialist Chris Sembroski — orbited the Earth at an altitude as high as 590 kilometers, which is above the International Space Station and the furthest humans have traveled above the surface in years. A free-flying spaceflight, the capsule did not dock with the ISS but instead circled the Earth independently at a rate of 15 orbits per day. Inspiration4 shared photos from the crew's time in orbit, giving a look at the expansive views from the spacecraft's "cupola" window. This is the third time SpaceX has returned astronauts from space, and the second time for this capsule — which previously flew the Crew-1 mission for NASA on a trip that returned in May.

NASA to Announce Landing Site for Artemis Lunar Robotic Rover

Scientists found evidence that a region of northern Mars called Arabia Terra experienced thousands of "super eruptions," the biggest volcanic eruptions known, over a 500-million-year period. NASA reports the findings in a post: Some volcanoes can produce eruptions so powerful they release oceans of dust and toxic gases into the air, blocking out sunlight and changing a planet's climate for decades. By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists recently found evidence for thousands of such eruptions, or "super eruptions," which are the most violent volcanic explosions known. Spewing water vapor, carbon dioxide, and sulfur dioxide into the air, these explosions tore through the Martian surface over a 500-million-year period about 4 billion years ago. Scientists reported this estimate in a paper published in the journal Geophysical Research Letters in July 2021. "Each one of these eruptions would have had a significant climate impact -- maybe the released gas made the atmosphere thicker or blocked the Sun and made the atmosphere colder," said Patrick Whelley, a geologist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, who led the Arabia Terra analysis. "Modelers of the Martian climate will have some work to do to try to understand the impact of the volcanoes." [...] One remaining question is how a planet can have only one type of volcano littering a region. On Earth volcanoes capable of super eruptions -- the most recent erupted 76,000 years ago in Sumatra, Indonesia -- are dispersed around the globe and exist in the same areas as other volcano types. Mars, too, has many other types of volcanoes, including the biggest volcano in the solar system called Olympus Mons. Olympus Mons is 100 times larger by volume than Earth's largest volcano of Mauna Loa in Hawaii, and is known as a "shield volcano," which drains lava down a gently sloping mountain. Arabia Terra so far has the only evidence of explosive volcanoes on Mars. It's possible that super-eruptive volcanoes were concentrated in regions on Earth but have been eroded physically and chemically or moved around the globe as continents shifted due to plate tectonics. These types of explosive volcanoes also could exist in regions of Jupiter's moon Io or could have been clustered on Venus. Whatever the case may be, Richardson hopes Arabia Terra will teach scientists something new about geological processes that help shape planets and moons.

SpaceX has successfully launched the crew of Inspiration4 into orbit. It's the first-ever orbital flight crewed entirely by tourists. From a report: The SpaceX rocket blasted off from NASA's Kennedy Space Center just after 8 p.m. ET. The crew includes 38-year-old billionaire Jared Isaacman, who personally financed the trip; Hayley Arceneux, 29, a childhood cancer survivor and current St. Jude physician assistant; Sian Proctor, 51, a geologist and community college teacher with a PhD; and Chris Sembroski, a 42-year-old Lockheed Martin employee and lifelong space fan who claimed his seat through an online raffle. The passengers will now spend three days aboard their 13-foot-wide Crew Dragon capsule in orbit at a 350-mile altitude.

The world's first crew of "amateur astronauts" is preparing to blast off on a mission that will carry them into orbit before bringing them back down to Earth at the weekend. From a report: The four civilians, who have spent the past few months on an astronaut training course, are due to launch on SpaceX's Falcon 9 rocket from the Kennedy Space Center in Florida at 8.02pm local time on Wednesday (1.02am UK time on Thursday). Barring any glitches, the two men and two women on the Inspiration4 mission are expected to orbit the planet for three or four days, performing experiments and admiring the view through a glass dome fitted to their Dragon capsule, before splashing down in the Atlantic Ocean. Touted as "the world's first all-civilian mission to orbit," the launch is the latest to promote the virtues of space tourism and follows suborbital flights in July by Sir Richard Branson on Virgin Galactic's SpaceShipTwo -- which has since been grounded for going off course -- and Jeff Bezos on Blue Origin's New Shepard rocket. While the Inspiration4 crew has had flying lessons, centrifuge sessions to experience the G-forces of launch, and hours of training in SpaceX's capsule simulator, the mission will be almost entirely automated. The capsule is due to orbit Earth at an altitude of 360 miles (575km), about 93 miles higher than the International Space Station.
