Agnikul Cosmos successfully test fires engine to power Agnibaan rocket
This capability allows for higher accuracy and rapid response—critical for managing complex flight trajectories and mission requirements. During the test, the engine was throttled across a wide range of thrust levels, demonstrating the flexibility and reliability of the technology. Unlike conventional rocket engines that rely on gas generators or turbopumps, Agnikul's semi-cryogenic engine uses an electric motor to power the pumps that circulate propellants—a combination of liquid oxygen (cryogenic oxidizer) and refined kerosene (non-cryogenic fuel).This approach is not only more efficient but also allows for easier integration of advanced control systems.Agnikul's signature single-piece engine design remains central to this new system. Many of the engine's pump subsystems were 3D-printed and assembled at the company's AS9100D-certified Rocket Factory-1, located at the IIT Madras Research Park in Chennai.The motor drives and associated control software were also designed and developed entirely in-house.advertisementThe successful test is a key step toward firing a cluster of these engines together, a crucial requirement for powering the Agnibaan rocket.Agnibaan, which can be configured to carry payloads ranging from 30 kg to 300 kg, is designed to serve the growing demand for affordable and customisable satellite launches.

Apollo, Ares Eye Bigger Role Backing Sports Leagues, Teams
(Bloomberg) -- Apollo Global Management Inc. and Ares Management Corp. are both pushing deeper into sports investing, the latest multibillion-dollar alternative asset managers to put more money into the booming sector. Ares has begun talking to investors about a new media and entertainment fund designed for individuals, a departure from the traditionally exclusive nature of sports finance. The semi-liquid fund will target both debt and equity investments across sports leagues and businesses. Meanwhile, Apollo is considering creating a permanent capital vehicle dedicated to sports finance, a structure that would allow for longer-term and strategic investments in the industry. The fund would primarily lend to professional sports teams and leagues, with the option to take equity positions. Alts managers like Ares and Apollo have been pouncing on opportunities to invest in sports teams, boosted by the National Football League's landmark decision last year to allow private equity firms to own teams. In May, Bloomberg reported that a group of professional sports team insiders, including billionaire Dallas Mavericks minority owner Mark Cuban, were launching a private equity fund aimed at taking small stakes in pro sports teams. Arctos Partners, CVC Capital Partners and Ares have also been investing in leagues and teams, while Elliott Management Corp. and Oaktree Capital Management took ownership of football clubs after owners defaulted on their loans. The Ares fund will align with its push to reach individual investors and came in response to growing demand from financial advisers seeking to expose their retail clients to the asset class. Ares aims to capture $100 billion in assets from individual investors by 2028, an area that makes up 8% of its $546 billion asset base. If successful, the initiative could generate an estimated $600 million in management fees, it said. Los Angeles-based Ares has also been ramping up its investments in sports, buying stakes in the NFL's Miami Dolphins and other teams and closing its first fund dedicated to the strategy in 2022 with $3.7 billion. Meanwhile, New York-based Apollo has already signed a number of sports deals through existing pools of capital, including issuing loans to football teams such as Sporting Lisbon and Nottingham Forest. 'While sports teams, clubs and leagues often draw much of the attention, we believe the broader potential ecosystem of sports, media and entertainment investing is significant and underpenetrated,' Ares has said on its website. The firm has estimated the total investment opportunity in 'adjacent strategies' could be as much as $2.5 trillion. (Updates with potential investment opportunity figures in last paragraph.)

Gulf Air Orders 12 New Boeing And 787 Dreamliners
US aviation giant Boeing on Thursday signed a contract worth billions of dollars to sell 12 787 Dreamliners, with options for six more, to Gulf Air, as the Bahrain-based carrier looks to expand its global network. The order comes one month after an Air India Boeing 787 crashed shortly after takeoff, killing a total of 260 people on the plane and on the ground. "Once finalised, this order will bring the carrier's firm order book to 14 of the versatile wide-body jets and will support 30,000 jobs across the US," the companies said in a joint statement. The official Bahrain News Agency said the kingdom's national carrier had signed a $4.6 billion agreement for 18 Boeing 787 Dreamliners. The US Commerce Department put the value of the 18 planes at $7 billion. The deal "marks a transformative step in Gulf Air's strategic growth journey as we expand our global footprint and modernise our fleet with one of the industry's most advanced and efficient aircraft," said Gulf Air Group chairman Khalid Taqi. "The Boeing 787 Dreamliner has proven to be an exceptional aircraft for our long-haul operations, and this new order reflects our confidence in its performance, passenger appeal and contribution to our sustainability goals." Boeing delivered 150 commercial aircraft in the second quarter, its highest number of deliveries in that quarter since 2018. That was just before two 737 MAX crashes in October 2018 and March 2019 -- which killed 346 people -- plunged the company into crisis. The Air India jet bound for London crashed in the Indian city of Ahmedabad on June 12. A preliminary investigation report revealed that the fuel control switches were switched off shortly after takeoff. Boeing has not been asked to take any action as the probe continues. US President Donald Trump on Tuesday announced a trade pact with Indonesia that limits tariffs on Indonesian products at 19 percent, and said the deal features a pledge from the country to buy 50 Boeing jets, "many of them 777s."

Humana Falls After Losing Bid to Reverse Medicare Bonus Cuts
(Bloomberg) -- Humana Inc. shares fell after it lost a lawsuit seeking to reverse cuts to its Medicare bonus payments, a blow for the insurer that had hoped the court would restore billions in revenue. A Texas judge ruled in favor of a government motion to dismiss the case, allowing a downgrade of Humana's Medicare quality ratings that's set to squeeze the company's profits in 2026. Humana shares dropped as much as 7.5% before paring losses. The judge called Humana's federal court claim 'premature' because the company hadn't exhausted all the administrative procedures over the decision. The lawsuit was dismissed 'without prejudice,' which means Humana could file the court case again. 'Plaintiffs can seek review, just not until the end of the administrative appeal process,' the judge wrote. In April, the insurer lost an administrative appeal with the Centers for Medicare and Medicare Services. In a court filing that month, the company argued that the administrative decision should invalidate one of the government's arguments for dismissing the suit. US District Court Judge Reed O'Connor disagreed. While he acknowledged the administrative appeal was over, he wrote that 'when filed, this action was premature,' and the court could not rule on the merits. That decision could pave the way for the company to quickly challenge the ratings in a fresh lawsuit. Humana will explore its legal options, including 'either an appeal of today's order or a refiling of the lawsuit,' a spokesperson said in an email. CMS didn't immediately respond to a request for comment. Other insurer stocks fell Friday, with Elevance Health Inc. declining as much as 7.6%. Molina Healthcare Inc. shares fell as much as 5.6%. They'd already been under pressure due to challenges in government insurance programs from Medicare to Medicaid and the Affordable Care Act markets. The decision is a defeat for the insurance giant in a high-stakes legal gambit to challenge unfavorable results on its Medicare quality scores. A win would have almost doubled Humana's 2026 profit, Barclays analysts wrote in April, to $27.74 a share. Humana filed the lawsuit in October to challenge how the US Medicare program calculated the quality ratings, known as stars, for Humana's plans. The company suffered a surprise downgrade in its star ratings in October that sent shares plunging. The ratings are meant to reflect how well Medicare health plans take care of patients and how they perform on customer service, like handling complaints and service calls. High star ratings drive billions of dollars in Medicare bonus payments to private insurers. The program paid $11.8 billion in bonuses in 2024, including $2.5 billion to Humana, according to health research group KFF. More than any large health insurer, Louisville, Kentucky-based Humana is focused on Medicare Advantage, the private version of the US health program for seniors. Profit in that business is heavily linked to performing well on annual quality ratings. The company previously had about 94% of members in highly rated plans that pay bonuses, but that slipped to about 25% in the most recent assessment. In its October lawsuit, Humana argued that the Centers for Medicare and Medicaid Services erred in how it calculated the company's star ratings, and asked the court to throw out the negative scores. --With assistance from Steve Stroth.
