SpaceX’s first private flight has been launched into orbit with two contest winners, a healthcare worker and their rich sponsor on board, the most ambitious leap yet in space tourism.
The launch on Wednesday night was the first time a spacecraft circled Earth with an all-amateur crew and no professional astronauts.
“Punch it, SpaceX!” the flight’s billionaire leader, Jared Isaacman, urged moments before liftoff.
The Dragon capsule’s two men and two women are looking to spend three days circling the planet from an unusually high orbit – 160km (100 miles) higher than the International Space Station – before splashing down off the Florida coast this weekend.
It is SpaceX founder Elon Musk’s first entry in the competition for space tourism dollars.
Isaacman is the third billionaire to launch this summer, following the brief space-skimming flights by Virgin Galactic’s Richard Branson and Blue Origin’s Jeff Bezos in July. Only 38, Isaacman made his fortune from a payment-processing company he started in his teens.
Joining Isaacman on the trip dubbed Inspiration4 is Hayley Arceneaux, 29, a childhood bone cancer survivor who works as a physician assistant where she was treated – St Jude Children’s Research Hospital in Memphis, Tennessee. Isaacman has pledged $100m out of his own pocket to the hospital and is seeking another $100m in donations.
Arceneaux became the youngest American in space and the first person in space with a prosthesis, a titanium rod in her left leg.
Also along for the ride are sweepstakes winners Chris Sembroski, 42, a data engineer in Everett, Washington, and Sian Proctor, 51, a community college educator in Tempe, Arizona.
Once opposed to space tourism, NASA is now a supporter.
“Low-Earth orbit is now more accessible for more people to experience the wonders of space,” tweeted NASA Administrator Bill Nelson, who was a congressman when he hitched a ride on a space shuttle decades ago.
NASA Lucy Mission: Are Solar System Stem Cells Orbiting Jupiter? – The Press Stories

A spacecraft was sent from Cape Canaveral to explore the fossil record in the solar system.
Lucy is a spacecraft orbiting Jupiter (Jupiter-Jupiter) to study clusters of two asteroids. One of them is in front of Jupiter in the orbit of the campus. The other is in the back.
NASA scientists say the study of these asteroids could help understand the effects of the first phase of solar system formation.
The Lucy spacecraft was launched from the Cape Canaveral in Florida at 9.45am on Saturday on an Atlas-5 rocket.
NASA initially decided to spend $ 98.1 billion (approximately Rs. 7,360 crore) on the mission over a twelve-year period.
There is a human fossil in Africa called Lucy. It was this fossil that helped us learn more about the existence of the human race.
Due to its inspiration, NASA carries out this mission under the same name.
“Trojan meteorites orbit Jupiter at 60 degrees,” said Hall Lewison of the Southwest Research Institute in Colorado. He was the leading researcher on the Lucy spacecraft.
“Under the influence of the gravitational pull of Jupiter and the Sun, these asteroids are constantly orbiting in that orbit. If any object falls there in the early days of the solar system, it will always be stable. So these fragments are fossils of what the planets are made of,” said Hall Louison.
Lucy explores many factors such as the shape, texture, surface conditions and composition of the materials that make up their pieces that are the size of the city or larger.
Jupiter is examining whether these fragments are derived from objects found on satellites.
“For example, if they were made of the same materials as we call the Khyber belt, we would assume that they are made of the Khyber belt and then rotate,” said Dr. Carly Howet, a Southwest Mission scientist. Research Institute.
Carly said the task was the result of some unusual navigation calculations.
Lucy will travel a total of 600 million kilometers. It will explore the Trojan complex in 2027/28. Jupiter will then reach the clusters of pieces on the other side in 2033.

Astronauts capture stunning aurora from International Space Station – Space.com
Astronauts got to see an amazing display of southern lights over New Zealand and Antarctica earlier this month.
“I caught this aurora just as orbital sunrise was beginning. Breathtaking!” wrote NASA astronaut Shane Kimbrough on Oct. 12, two days after the show took place. With his tweet came a sweeping view of auroras over the barely lit limb of the Earth.
Auroras take place when charged particles from the sun, known as the solar wind, flow along the magnetic field lines of Earth and interact with our atmosphere. As the particles are deflected by the magnetic field to our planet’s poles, their interactions with the atmosphere dumps in energy and causes the atmosphere to glow.

The sun is somewhat near the beginning of a solar cycle, which lasts about 11 years. Each cycle has a “maximum,” at which point there is more solar activity manifested as solar flares and coronal mass ejections, which can cause auroras if any particles flow in the right direction towards Earth.
While we’re not near that maximum phase right now, the astronauts had a great viewpoint from their orbit at approximately 250 miles (400 km) above Earth, with no interfering atmosphere in the way. That said, French astronaut Thomas Pesquet said eventually the sun stopped observations.
“The view in this #timelapse passes the #aurora to marvel at the stars and then be overwhelmed by a sunrise,” Pesquet wrote in a tweet posted on Sunday (Oct. 17).
Although the aurora is beautiful, it could accompany a real danger for astronauts: radiation. NASA has lifetime radiation protocols in place for its spaceflyers to protect against ill effects of radiation events in orbit, which can be associated with conditions such as cancer. The agency is also investigating the exposure for astronauts at future spaceflight destinations such as the moon and Mars.

Australia must commit to carbon cuts to keep green energy advantage -Fortescue’s Forrest
Australia risks losing its advantage in the green energy revolution if its leaders don’t promptly commit to cutting carbon emissions by 2050, the country’s richest man, Fortescue Metals Group founder Andrew Forrest said on Monday.
Forrest, who grew Fortescue from a minnow to rival the world’s biggest mining giants in less than two decades, has spearheaded his company’s global green energy drive, signing deals from Brazil to Indonesia to Democratic Republic of Congo.
The company aims to build a 250 megawatt hydrogen electrolyser at Bell Bay in Tasmania — 25 times the size of the biggest existing electrolysers in the world — for less than A$1 billion ($740 million), Forrest said, putting a price on the project for the first time.
Fortescue is ready to make a final investment decision this year, as promised, but is waiting for support from the state government before going ahead with the project.
While Forrest told Reuters that Australia is the best place to realise his green vision, the country’s failure to commit to a policy to cut emissions is risking that advantage.
“I would say 2050 neutrality is a certainty for Australia. If we support it by COP26 the dividend flow to regional Australia will be substantial. If we don’t support it by COP26, the future will remain uncertain,” Forrest said, referring to the COP 26 climate conference in Glasgow at the end of October.
“The renewable energy, green hydrogen, green ammonia, green electricity industry is very, very mobile,” he said.
“It is where the will is strongest – they will be the first to be developed.”
Australia’s energy policy is again in the spotlight as Prime Minister Scott Morrison prepares to attend the conference, where global leaders will meet to set further climate goals to follow on from the landmark 2015 Paris accord.
But Morrison is short on updated climate ambitions to bring to the table given his reliance on the junior partner in Australia’s coalition government which said it would not be rushed into a decision on whether to support a target of net zero emissions by 2050.
The Nationals who represent coal and farming heartlands worry that stronger emissions targets will cost jobs. Coal is the country’s second biggest export earner.
But Forrest, speaking to Reuters from London, said that rural Australians were set to be the biggest winners in the move to green energy – if agreements are made in time.
“I have demonstrated investment into the regions despite the fact Australia is dragging the chain,” Forrest told Reuters.
Fortescue is investigating the potential to convert top Australian fertiliser maker Incitec Pivot’s Brisbane ammonia plant to use green hydrogen as a feedstock instead of natural gas, with an on-site electrolysis plant that will produce up to 50,000 tonnes of hydrogen a year.
The plant’s future had been under threat due to soaring gas prices, however setting up a green hydrogen production site to feed the existing plant could save 400 jobs and create many more, Forrest said.
At the same time, the product from the plant will be cheaper for local farmers.
“So farmers in Australia long into the future can plan for the next season, or even for the next generation … knowing that fertilisers are coming from a hydrogen molecule that is infinite,” Forrest said.
