‘Touch the sun’: NASA spacecraft hurtles toward our star

CAPE CANAVERAL, Florida: Embarking on a mission that scientists have been dreaming of since the Sputnik era, a NASA spacecraft hurtled Sunday toward the sun on a quest to unlock some of its mysteries by getting closer than any object sent before.
If all goes well, the Parker Solar Probe will fly straight through the wispy edges of the sun’s corona, or outer atmosphere, in November. In the years ahead, it will gradually get within 3.8 million miles (6 million kilometers) of the surface, its instruments protected from the extreme heat and radiation by a revolutionary new carbon heat shield and other high-tech wizardry.
Altogether, the Parker probe will make 24 close approaches to our star during the seven-year, $1.5 billion journey.
“Wow, here we go. We’re in for some learning over the next several years,” said Eugene Parker, the 91-year-old astrophysicist for whom the spacecraft is named.
It was Parker who accurately theorized 60 years ago the existence of solar wind — the supersonic stream of charged particles blasting off the sun and coursing through space, sometimes wreaking havoc on electrical systems on Earth.
This is the first time NASA has named a spacecraft after a living person.

As Parker and thousands of others watched, a Delta IV Heavy rocket carried the probe aloft, thundering into the clear, star-studded sky on three pillars of fire that lit up the middle-of-the-night darkness.
NASA needed the mighty 23-story rocket, plus a third stage, to get the Parker probe — the size of a small car and well under a ton — racing toward the sun, 93 million miles (150 million kilometers) from Earth.
A Saturday morning launch attempt was foiled by last-minute technical trouble. But Sunday gave way to complete success.
It was the first rocket launch ever witnessed by Parker, a retired University of Chicago professor. He said it was like looking at photos of the Taj Mahal for years and then beholding the real thing in India.
“I really have to turn from biting my nails in getting it launched, to thinking about all the interesting things which I don’t know yet and which will be made clear, I assume, over the next five or six or seven years,” Parker said on NASA TV.
Among the mysteries scientists hope to solve: Why is the corona hundreds of times hotter than the surface, which is 10,000 degrees Fahrenheit (5,500 degrees Celsius)? And why is the sun’s atmosphere continually expanding and accelerating, as Parker theorized in 1958?
“The only way we can do that is to finally go up and touch the sun,” said project scientist Nicola Fox of Johns Hopkins University. “We’ve looked at it. We’ve studied it from missions that are close in, even as close as the planet Mercury. But we have to go there.”
A better understanding of the sun’s life-giving and sometimes violent nature could also enable earthlings to better protect satellites and astronauts in orbit, along with the power grids so vital to today’s technology-dependent society, said Thomas Zurbuchen, NASA’s science mission chief.
Parker, the probe, will start shattering records this fall. On its very first brush with the sun, it will come within 15.5 million miles (25 million kilometers), easily beating the current record of 27 million miles (43 million kilometers) set by NASA’s Helios 2 spacecraft in 1976.
By the time Parker gets to its 22nd, 23rd and 24th orbits of the sun in 2024 and 2025, it will be even deeper into the corona and traveling at a record 430,000 mph (690,000 kilometers per hour). Nothing from planet Earth has ever gone that fast.
Even Fox has difficulty comprehending the mission’s derring-do.
“To me, it’s still mind-blowing,” she said. “Even I still go, ‘Really? We’re doing that?’“
The 8-foot (2.4-meter) heat shield will serve as an umbrella that will shade the spacecraft’s scientific instruments, with on-board sensors adjusting the protective cover as necessary so that nothing gets fried.
A mission to get up close and personal with our star has been on NASA’s books since 1958. The trick was making the spacecraft compact and light enough to travel at incredible speeds and durable enough to withstand the punishing environment.
“We’ve had to wait so long for our technology to catch up with our dreams,” Fox said.

SpaceX’s first private passenger is Japanese fashion magnate Maezawa

  • SpaceX in February transfixed a global audience with the successful test launch of its Falcon Heavy, the most powerful operational rocket in the world
  • SpaceX has already upended the space industry with its relatively low-cost reusable Falcon 9 rockets

HAWTHORNE, California: SpaceX, Elon Musk’s space transportation company, on Monday named its first private passenger as Japanese businessman Yusaku Maezawa, the founder and chief executive of online fashion retailer Zozo.
A former drummer in a punk band, billionaire Maezawa will will take a trip around the moon aboard its forthcoming Big Falcon Rocket spaceship, taking the race to commercialize space travel to new heights.
The first passenger to travel to the moon since the United States’ Apollo missions ended in 1972, Maezawa’s identity was revealed at an event Monday evening at the company’s headquarters and rocket factory in the Los Angeles suburb of Hawthorne.
In moves typical of his publicity-seeking style, Musk, who is also the billionaire chief executive of electric car maker Tesla Inc, had previously teased a few tantalizing details about the trip and the passenger’s identity, but left major questions unanswered.
On Thursday, Musk tweeted a picture of a Japanese flag. He followed that up on Sunday with tweets showing new artist renderings of the Big Falcon Rocket, or BFR, the super heavy-lift launch vehicle that Musk promises will shuttle the passenger to the moon and eventually fly humans and cargo to Mars, using the hashtag #OccupyMars.
While the BFR has not been built yet, Musk has said he wants the rocket to be ready for an unpiloted trip to Mars in 2022, with a crewed flight in 2024, though his ambitious production targets have been known to slip.
SpaceX plans a lunar orbit mission. It was not clear how much Maezawa paid for the trip.
Maezawa made his fortune by founding the wildly popular shopping site Zozotown. His company Zozo, officially called Start Today Co. Ltd, also offers a made-to-measure service using a polka dot bodysuit, the Zozosuit..
With SpaceX, Amazon.com founder Jeff Bezos’ Blue Origin and entrepreneur Richard Branson’s Virgin Galactic battling it out to launch private-sector spacecraft, the SpaceX passenger will join a growing list of celebrities and the ultra-rich who have secured seats on flights offered on the under-development vessels.
Those who have signed up to fly on Virgin Galactic sub-orbital missions include actor Leonardo DiCaprio and pop star Justin Bieber. A 90-minute flight costs $250,000.
Short sightseeing trips to space aboard Blue Origin’s New Shepard rocket are likely to cost around $200,000 to $300,000, at least to start, Reuters reported in July.
SpaceX has already upended the space industry with its relatively low-cost reusable Falcon 9 rockets. The company has completed more than 50 successful Falcon launches and snagged billions of dollars’ worth of contracts, including deals with NASA and the US Department of Defense.
SpaceX in February transfixed a global audience with the successful test launch of its Falcon Heavy, the most powerful operational rocket in the world.
SpaceX previously announced plans to eventually use Falcon Heavy to launch paying space tourists on a trip around the moon, but Musk said in February he was inclined to reserve that mission for the BFR.
