Spacewalking And More: US Billionaire Announces 3 More SpaceX Flights
U.S. billionaire Jared Isaacman, who chartered the first universal orbital spaceflight, announced on Monday that he is teaming up with SpaceX on three other private missions — including spacewalks that will fly in the next generation It culminates in the first manned flight of the Starship rocket.
The first, called Polaris Dawn, will take place no earlier than the fourth quarter of this year and will be led by Isaacman, founder of payment processing company Shift4.
The program represents a new step in commercial spaceflight as Elon Musk’s SpaceX seeks to take on more ambitious missions that have always been the domain of the national space agency.
During the press conference, Isaacman announced that he and SpaceX are co-funding Project Polaris, named after Polaris. He declined to provide further details, such as the total cost or the percentage the parties would contribute.
However, it is widely expected to be in the hundreds of millions of dollars.
“This program is specifically designed to increase the possibility of long-term space travel … and lead us toward our ultimate goal of advancing Mars exploration,” Isaacman told reporters.
A seasoned pilot, he led the Inspiration4 mission last year, a three-day orbital mission with a four civilian crew aboard a SpaceX Dragon spacecraft that raised $240 million for St. Jude Children’s Research Hospital.
For Polaris Dawn, the crew will go deeper into space than any previous dragon has flown — an altitude Isaacman says will be similar to NASA’s Gemini project, the agency’s second crewed spaceflight program in the 1960s.
Gemini 11 flew about 850 miles (1,370 kilometers), deeper into space than the most recent mission on the 250-mile International Space Station.
But the Apollo-era journey to the moon is still a long way off, and the moon is roughly 239,000 miles — or 30 Earths in a row — far apart.
The Polaris Dawn crew will also conduct the first commercial spacewalk, which will require a new yet-to-be-developed outer vehicle spacesuit.
Since the dragon has no airlock, opening the hatch would expose the entire spacecraft to the vacuum of space.
Mission specialist and medical officer Anna Menon said the crew would “make sure everything is well protected before we open the hatch.”
The spacecraft will launch from the Kennedy Space Center in Florida on a Falcon 9 rocket and will remain in orbit for up to five days.
The crew’s expected altitude will lead them into the interior of the Van Allen Belt, an area of dangerous radiation that protects Earth from the solar wind.
The Dragon’s fuselage and new spacesuit will help protect the crew, who will measure radiation exposure throughout the flight, added former NASA employee Menon, whose husband is named Anil Menon, His husband is the latest addition to NASA’s astronaut candidates.

Nasa’s old map of Jupiter, which reminds many of dosa, has gone viral once more
Certain images or videos frequently resurface on the Internet, leaving people speechless. When those clips or pictures are shared again on one social media platform or another, they create a buzz. The National Aeronautics and Space Administration (Nasa) created and posted this image of a map of Jupiter online a few years ago. After being shared on Twitter, the image drew a lot of attention this time. And, as usual, the image made people think of dosa, a popular South Indian dish.
The image was shared by the Twitter account Latest in Space. “From the very bottom of Jupiter, I’m looking up. While tweeting the image, they wrote, “Seen by NASA Cassini.” The images from the Cassini spacecraft’s narrow-angle camera were used to create this out-of-this-world image, which is part of a coloured map series produced by the space agency.
The article was published a few days ago. The tweet has received nearly 20,000 likes since it was shared, and the number is growing. The tweet has been retweeted more than 2,000 times. Take a look at some of the comments to see how the image of Jupiter looks like dosa.
A Twitter user commented, “Looks like a designer dosa.” “When I rush to pick up a call, this is what happens to my dosa on the dosa pan,” one joked. “This is how my mother makes Dosa,” a third said. “Jupiter in the making,” wrote a fourth, along with a photo of someone preparing – you guessed it – dosa.
