India launches spacecraft to study the sun after successful landing near the moon's south pole
India launched its first space mission to study the sun on Saturday, less than two weeks after a successful uncrewed landing near the south polar region of the moon.
The Aditya-L1 spacecraft took off on board a satellite launch vehicle from the Sriharikota space center in southern India on a quest to study the sun from a point about 1.5 million kilometers (930,000 miles) from earth.

The spacecraft is equipped with seven payloads to study the sun's corona, chromosphere, photosphere and solar wind, the Indian Space Research Organization said.
India became the first country to land a spacecraft near the moon's south pole on Aug. 23 — a historic voyage to uncharted territory that scientists believe could hold vital reserves of frozen water. After a failed attempt to land on the moon in 2019, India joined the United States, the Soviet Union and China as only the fourth country to achieve this milestone.
The sun study, combined with India's successful moon landing, would completely change the image of ISRO in the world community, said Manish Purohit, a former ISRO scientist.

The Aditya-L1 was headed for the L1 point of the Earth-Sun system, which affords an uninterrupted view of the sun, ISRO said. "This will provide a greater advantage of observing solar activities and their effect on space weather in real-time."
Once in place, the satellite would provide reliable forewarning of an onslaught of particles and radiation from heightened solar activity that has the potential to knock out power grids on Earth, said B.R. Guruprasad, a space scientist, in an article in The Times of India newspaper. The advanced warning can protect the satellites that are the backbone of global economic structure as well as the people living in space stations.

"Those seven payloads are going to study the sun as a star in all the possible spectrum positions that we have visible, ultraviolet, and X-ray. … It's like we're going to get a black and white image, the color image and the high-definition image, 4K image of the sun, so that we don't miss out on anything that is happening on the sun," Purohit said.

Blue Origin’s Bezos reaches space on 1st passenger flight
Jeff Bezos blasted into space Tuesday on his rocket company’s first flight with people on board, becoming the second billionaire in just over a week to ride his own spacecraft.
The Amazon founder was accompanied by a hand-picked group: his brother, an 18-year-old from the Netherlands and an 82-year-old aviation pioneer from Texas — the youngest and oldest to ever fly in space.
Named after America’s first astronaut, Blue Origin’s New Shepard rocket soared from remote West Texas on the 52nd anniversary of the Apollo 11 moon landing, a date chosen by Bezos for its historical significance. He held fast to it, even as Virgin Galactic’s Richard Branson pushed up his own flight from New Mexico in the race for space tourist dollars and beat him to space by nine days.
Unlike Branson’s piloted rocket plane, Bezos’ capsule was completely automated and required no official staff on board for the anticipated 10-minute, up-and-down flight.
Blue Origin was shooting for an altitude of roughly 66 miles (106 kilometers), more than 10 miles (16 kilometers) higher than Branson’s July 11 ride. The 60-foot (18-meter) booster accelerated to Mach 3 or three times the speed of sound to get the capsule high enough, before separating and aiming for a vertical landing.
The passengers were expected to get three to four minutes of weightlessness to float around the spacious white capsule. Then the window-filled capsule was going to head to a parachute touchdown on the desert floor, with Bezos and his guests briefly experiencing nearly six times the force of gravity, or 6 G’s, on the way back.

Sharing Bezos’ dream-come-true adventure was Wally Funk, from the Dallas area, one of 13 female pilots who went through the same tests as NASA’s all-male astronaut corps in the early 1960s but never made it into space.
Joining them on the ultimate joyride was the company’s first paying customer, Oliver Daemen, a last-minute fill-in for the mystery winner of a $28 million auction who opted for a later flight. The Dutch teen’s father took part in the auction, and agreed on a lower undisclosed price last week when Blue Origin offered his son the vacated seat.
Blue Origin — founded by Bezos in 2000 in Kent, Washington, near Amazon’s Seattle headquarters — has yet to open ticket sales to the public or reveal the price. For now, it’s booking auction bidders. Two more passenger flights are planned by year’s end, said Blue Origin CEO Bob Smith.
The recycled rocket and capsule that carried up Tuesday’s passengers were used on the last two space demos, according to company officials.
Virgin Galactic already has more than 600 reservations at $250,000 apiece. Founded by Branson in 2004, the company has sent crew into space four times and plans two more test flights from New Mexico before launching customers next year.
Blue Origin’s approach was slower and more deliberate. After 15 successful unoccupied test flights to space since 2015, Bezos finally declared it was time to put people on board. The Federal Aviation Administration agreed last week, approving the commercial space license.
Bezos, 57, who also owns The Washington Post, claimed the first seat. The next went to his 50-year-old brother, Mark Bezos, an investor and volunteer firefighter, then Funk and Daemen. They spent two days together in training.
University of Chicago space historian Jordan Bimm said the passenger makeup is truly remarkable. Imagine if the head of NASA decided he wanted to launch in 1961 instead of Alan Shepard on the first U.S. spaceflight, he said in an email.

“That would have been unthinkable!” Bimm said. “”It shows just how much the idea of who and what space is for has changed in the last 60 years.”
Bezos stepped down earlier this month as Amazon’s CEO and just last week donated $200 million to renovate the National Air and Space Museum. Most of the $28 million from the auction has been distributed to space advocacy and education groups, with the rest benefiting Blue Origin’s Club for the Future, its own education effort.
Fewer than 600 people have reached the edge of space or beyond. Until Tuesday, the youngest was 25-year-old Soviet cosmonaut Gherman Titov and the oldest at 77 was Mercury-turned-shuttle astronaut John Glenn.
Both Bezos and Branson want to drastically increase those overall numbers, as does SpaceX’s Elon Musk, who’s skipping brief space hops and sending his private clients straight to orbit for tens of millions apiece, with the first flight coming up in September.
Despite appearances, Bezos and Branson insist they weren’t trying to outdo each other by strapping in themselves. Bezos noted this week that only one person can lay claim to being first in space: Soviet cosmonaut Yuri Gagarin, who rocketed into orbit on April 12, 1961.
“This isn’t a competition, this is about building a road to space so that future generations can do incredible things in space,” he said on NBC’s ”Today.”
Blue Origin is working on a massive rocket, New Glenn, to put payloads and people into orbit from Cape Canaveral, Florida. The company also wants to put astronauts back on the moon with its proposed lunar lander Blue Moon; it’s challenging NASA’s sole contract award to SpaceX.

NASA picks Venus as hot spot for two new robotic missions
NASA is returning to sizzling Venus, our closest yet perhaps most overlooked neighbor, after decades of exploring other worlds.
The space agency’s new administrator, Bill Nelson, announced two new robotic missions to the solar system’s hottest planet, during his first major address to employees Wednesday.

“These two sister missions both aim to understand how Venus became an inferno-like world capable of melting lead at the surface,” Nelson said.
One mission named DaVinci Plus will analyze the thick, cloudy Venusian atmosphere in an attempt to determine whether the inferno planet ever had an ocean and was possibly habitable. A small craft will plunge through the atmosphere to measure the gases.
It will be the first U.S.-led mission to the Venusian atmosphere since 1978.
The other mission, called Veritas, will seek a geologic history by mapping the rocky planet’s surface.

“It is astounding how little we know about Venus,” but the new missions will give fresh views of the planet’s atmosphere, made up mostly of carbon dioxide, down to the core, NASA scientist Tom Wagner said in a statement. “It will be as if we have rediscovered the planet.”
NASA’s top science official, Thomas Zurbuchen, calls it “a new decade of Venus.” Each mission — launching sometime around 2028 to 2030 — will receive $500 million for development under NASA’s Discovery program.
The missions beat out two other proposed projects, to Jupiter’s moon Io and Neptune’s icy moon Triton.
The U.S. and the former Soviet Union sent multiple spacecraft to Venus in the early days of space exploration. NASA’s Mariner 2 performed the first successful flyby in 1962, and the Soviets’ Venera 7 made the first successful landing in 1970.

Chinese cargo spacecraft docks with orbital station
An automated spacecraft docked with China’s new space station Sunday carrying fuel and supplies for its future crew, the Chinese space agency announced.
Tianzhou-2 spacecraft reached the Tianhe station eight hours after blasting off from Hainan, an island in the South China Sea, China Manned Space said. It carried space suits, living supplies and equipment and fuel for the station.

Tianhe, or Heavenly Harmony, is third and largest orbital station launched by China’s increasingly ambition space program.
The station’s core module was launched April 29. The space agency plans a total of 11 launches through the end of next year to deliver two more modules for the 70-ton station, supplies and a three-member crew.
China was criticized for allowing part of the rocket that launched the Tianhe to fall back to Earth uncontrolled. There was no indication about what would happen to the rocket from Saturday’s launch.

China’s Mars rover touches ground on red planet
China’s first Mars rover has driven down from its landing platform and is now roaming the surface of the red planet, China’s space administration said Saturday.
The solar-powered rover touched Martian soil at 10:40 a.m. Saturday Beijing time (0240 GMT), the China National Space Administration said.
China landed the spacecraft carrying the rover on Mars last Saturday, a technically challenging feat more difficult than a moon landing, in a first for the country. It is the second country to land and operate a spacecraft on Mars, after the United States.

Named after the Chinese god of fire, Zhurong, the rover has been running diagnostics tests for several days before it began its exploration Saturday. It is expected to be deployed for 90 days to search of evidence of life.
The U.S. also has an ongoing Mars mission, with the Perseverance rover and a tiny helicopter exploring the planet. NASA expects the rover to collect its first sample in July for return to Earth as early as 2031.
China has ambitious space plans that include launching a crewed orbital station and landing a human on the moon. China in 2019 became the first country to land a space probe on the little-explored far side of the moon, and in December returned lunar rocks to Earth for the first time since the 1970s.

China delays supply mission to newly launched space station
China postponed a supply mission to its new space station Thursday for unspecified technical reasons.
The Tianzhou-2 cargo spacecraft was expected to have been launched early Thursday morning. China Manned Space announced the delay on its website but didn’t say when the rescheduled launch may occur.
It would be the first mission to head to the main Tianhe module of the space station that was launched on April 29. Another 10 launches are planned to deliver the station’s other two modules, various components and supplies, and a three-person crew.
The launch of Tianhe, or Heavenly Harmony, was considered a success although China was criticized for allowing the uncontrolled reentry of part of the rocket that carried it into space.
Usually, discarded rocket stages reenter the atmosphere soon after liftoff, normally over water, and don’t go into orbit.
NASA Administrator Sen. Bill Nelson said at the time that China had failed to meet responsible standards regarding space debris.

China’s space program has suffered relatively few setbacks since it first put an astronaut into orbit in 2003, although the space station launch was delayed by the failure of an earlier version of the massive Long March 5B rocket.
Earlier this month, China also landed a probe and its accompanying rover on Mars and has begun sending back pictures from the surface of the red planet.
Only the United States has successfully landed and operated a spacecraft on Mars — nine times, beginning with the twin Vikings in 1976 and, most recently, with the Perseverance rover in February.
China also recently brought back lunar samples, the first by any country’s space program since the 1970s, and also landed a probe and rover on the moon’s less explored far side.
China earlier launched two smaller experimental space stations. It has been excluded from the International Space Station largely at the insistence of the United States, which is wary of the secrecy surrounding the Chinese space program and its close military links.
Despite that, China has entered into increasingly close cooperation in space with various European and other countries.
