NASA’s Orion capsule made a blisteringly fast return from the Moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.

The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants — three test dummies rigged with vibration sensors and radiation monitors.

NASA hailed the descent and splashdown as close to perfect, as congratulations poured in from Washington..

“I’m overwhelmed,” NASA Administrator Bill Nelson said from Mission Control in Houston. “This is an extraordinary day… It’s historic because we are now going back into space — deep space — with a new generation.”

The space agency needed a successful splashdown to stay on track for the next Orion flight around the Moon, targeted for 2024 with four astronauts who will be revealed early next year. That would be followed by a two-person lunar landing as early as 2025 and, ultimately, a sustainable Moon base. The long-term plan would be to launch a Mars expedition by the late 2030s.

Astronauts last landed on the Moon 50 years ago. After touching down on December 11, 1972, Apollo 17′s Eugene Cernan and Harrison Schmitt spent three days exploring the valley of Taurus-Littrow, the longest stay of the Apollo era. They were the last of the 12 Moonwalkers.

Orion was the first capsule to visit the Moon since then, launching on NASA’s new mega Moon rocket from Kennedy Space Center on November 16. It was the first flight of NASA’s new Artemis Moon program, named after Apollo’s mythological twin sister.

“From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of NASA’s journey to the Moon comes to a close. Orion back on Earth,” announced Mission Control commentator Rob Navias.

While no one was on the $4 billion test flight, NASA managers were thrilled to pull off the dress rehearsal, especially after so many years of flight delays and busted budgets. Fuel leaks and hurricanes conspired for additional postponements in late summer and fall.

In an Apollo throwback, NASA held a splashdown party at Houston’s Johnson Space Center on Sunday, with employees and their families gathering to watch the broadcast of Orion’s homecoming. Next door, the visitor center threw a bash for the public.

Getting Orion back intact after the 25-day flight was NASA’s top objective. With a return speed of 25,000 mph (40,000 kph) — considerably faster than coming in from low-Earth orbit — the capsule used a new, advanced heat shield never tested before in spaceflight. To reduce the gravity or G loads, it dipped into the atmosphere and briefly skipped out, also helping to pinpoint the splashdown area.

All that unfolded in spectacular fashion, officials noted, allowing for Orion’s safe return.

“I don’t think any one of us could have imagined a mission this successful,” said mission manager Mike Sarafin.

Further inspections will be conducted once Orion is back at Kennedy by month’s end. If the capsule checks find nothing amiss, NASA will announce the first lunar crew amid considerable hoopla in early 2023, picking from among the 42 active U.S. astronauts stationed at Houston’s Johnson Space Center.

“People are anxious, we know that,” Vanessa Wyche, Johnson’s director, told reporters. Added Nelson: “The American people, just like (with) the original seven astronauts in the Mercury days, are going to want to know about these astronauts.”

The capsule splashed down more than 300 miles (482 kilometers) south of the original target zone. Forecasts calling for choppy seas and high wind off the Southern California coast prompted NASA to switch the location.

Orion logged 1.4 million miles (2.25 million kilometers) as it zoomed to the Moon and then entered a wide, swooping orbit for nearly a week before heading home.

It came within 80 miles (130 kilometers) of the Moon twice. At its farthest, the capsule was more than 268,000 miles (430,000 kilometers) from Earth.

Orion beamed back stunning photos of not only the gray, pitted Moon, but also the home planet. As a parting shot, the capsule revealed a crescent Earth — Earthrise — that left the mission team speechless.

Nottingham Trent University astronomer Daniel Brown said the flight’s many accomplishments illustrate NASA’s capability to put astronauts on the next Artemis Moonshot.

“This was the nail-biting end of an amazing and important journey for NASA’s Orion spacecraft,” Brown said in a statement from England.

The Moon has never been hotter. Just hours earlier Sunday, a spacecraft rocketed toward the Moon from Cape Canaveral. The lunar lander belongs to ispace, a Tokyo company intent on developing an economy up there. Two U.S. companies, meanwhile, have lunar landers launching early next year.

NISAR Launches July 30: A NASA-ISRO Satellite to Track Earth’s Changes

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, a joint Earth science mission, is now set for launch from India’s Satish Dhawan Space Centre. The pickup-truck-sized spacecraft was encapsulated in the nose cone of an Indian Geosynchronous Satellite Launch Vehicle and is scheduled to lift off on Wednesday, July 30 at 8:10 a.m. EDT (5:40 p.m. IST). Once in orbit, its dual-frequency radars will circle Earth 14 times a day, scanning nearly all of the planet’s land and ice surfaces every 12 days. It will provide data to help scientists monitor soil moisture and vegetation, and better assess hazards like landslides and floods.

International Collaboration and Launch Readiness

According to the official website, NISAR reflects a significant NASA–ISRO partnership. NASA’s Jet Propulsion Laboratory (JPL) built the long-wavelength L-band radar, and India’s Space Applications Centre built the shorter-wavelength S-band radar. This dual-frequency design makes NISAR the first Earth satellite to carry two radar systems, underscoring the mission’s unique collaboration.

The spacecraft is now integrated into its launch vehicle at India’s Satish Dhawan Space Centre. On July 28 NASA announced NISAR had been encapsulated in the payload fairing of an ISRO Geosynchronous Satellite Launch Vehicle on the pad. The GSLV is scheduled to lift off at 8:10 a.m. EDT (5:40 p.m. IST) on Wednesday, July 30.

Advanced Dual-Frequency Radar

NISAR carries a novel dual-frequency radar system. The satellite’s instruments operate at L-band (25 cm) and S-band (10 cm) wavelengths. The longer L-band waves can penetrate forests and soil to sense moisture and land motion, while the shorter S-band waves pick up fine surface details like vegetation moisture and roughness. This combination lets NISAR detect both large-scale and fine-scale changes.

From orbit, NISAR will circle Earth 14 times per day, scanning nearly all land and ice surfaces twice every 12 days. Its data will track changes like the advance or retreat of polar ice sheets and slow ground shifts from earthquakes, and will also aid agriculture and disaster planning by helping monitor crops and prepare for floods and hurricanes.

Doomed Exoplanet TOI-2109b Spirals Toward Its Star with Three Possible Fates

Doomed Exoplanet TOI-2109b Spirals Toward Its Star with Three Possible Fates

The gas giant TOI-2109b is more than five times as massive as Jupiter, and resides in a perilous orbit 870 light-years from our planet. As an “ultrahot Jupiter,” it completes a lap around its parent star in a mere 16 hours, the briefest orbit of any such planet known. It is baking its atmosphere to broiling temperatures, and inching closer to oblivion in an orbit that is slowly pulling it in toward its parent sun. Using archived space telescope data from TESS and Cheops, astronomers have observed the testimony of this inevitable spiral, and contemplated three (wildly divergent) possible fates of the doomed planet.

Fates for TOI-2109b

According to the new research, conducted with data from NASA’s TESS and ESA’s Cheops missions shows that TOI-2109b’s orbit is decaying — a process it will continue for thousands of Earth’s years to come by 10 seconds over three Earth years. This proves that it is in a process of slow in fall. If the decay becomes worse, the planet may start falling directly into its host star and create a luminous flare, just like ZTF SLRN-2020. Alternatively, the star’s tidal forces could permanently warp the planet and rip it asunder.

A Potential Planetary Rebirth

There is a third, less-tragic possibility which could happen through a process of photoevaporation, in which strong radiation from the hosting star removes TOI-2109b’s gaseous envelope to reveal its rocky core. If the planet shrinks quickly enough, it might survive the process, avoiding its destruction by spiraling within its eternal Roche limit, and settling as a super-Earth or Neptune-sized blow-up hard relic. Then TOI-2109b would be an odd, rare opportunity to witness up close how this process unfolds.

Hubble Spots Interstellar Invader Comet 3I/ATLAS for the First Time

The Hubble Space Telescope has taken its initial shots of comet 3I/ATLAS, a comet visiting us from beyond our solar system that recently fell apart — but not before it struck a pose for the cameras. It’s only the third such object ever known, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019. The subject of numerous scientific tweets and some frantic searches by astronomers anxious to figure out just what it is — and where it came from — before it is gone into the pitch black of deep space forever, 3I/ATLAS was first sighted by the ATLAS survey telescope on July 1, 2025.

Ancient Interstellar Comet 3I/ATLAS Offers Clues to Planetary Systems Beyond Our Own

According to As per Space.com, recent studies indicate that 3I/ATLAS could be some 7 billion years old, well beyond the 4.6 billion years of our solar system. That’s an indication that the comet arose in the more ancient parts of the Milky Way, which would give researchers a rare glimpse of what the early days of other planetary systems were like. Undergraduate researcher Astrafoxen first flagged the Hubble images on Bluesky, noting the comet’s “nice and puffy” coma, despite interference from cosmic rays.

A newly available preprint paper has already revealed that 3I/ATLAS contains abundant water ice and a dust makeup resembling D-type asteroids—organic-rich bodies typically found in the outer solar system. Unlike ultrared trans-Neptunian objects, D-types are believed to have high carbon and silicate content, potentially shedding light on the comet’s deep-space origins and volatile chemistry.

The comet 3I/ATLAS was discovered just as the Vera C. Rubin Observatory was gearing up to carry out its initial observations of the heavens, dovetailing with the LSST’s expected discovery of many more interstellar objects in the coming decade.

Until then, 3I/ATLAS holds the astronomical spotlight. Its brief solar system passage offers a precious opportunity for researchers to analyse the material makeup of alien planetary systems. The Hubble images, now available for download, are expected to aid future papers as scientists continue to unravel the story of this ancient cosmic traveller.
