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.

NASA’s SPHEREx Telescope Launching Aboard SpaceX Falcon 9 to Explore Cosmic Evolution

NASA’s latest infrared space telescope, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), is set for launch on 28th February. The mission, valued at $488 million, will take off from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket. Designed to scan the entire sky in infrared light, it will collect data from over 450 million galaxies and 100 million stars in the Milky Way. The telescope’s observations will focus on regions of the universe that are typically too distant or faint for conventional telescopes.

Scientific Objectives

According to NASA, the primary aim of SPHEREx is to enhance understanding of cosmic inflation, the rapid expansion of the universe that occurred within the first second following the Big Bang. By mapping the large-scale structure of the cosmos, the telescope will provide insight into how galaxies formed and evolved. Scientists also anticipate that its data will help track the presence and distribution of icy molecules in interstellar space, shedding light on the origins of water and essential organic compounds required for life.

Technical Capabilities

As per NASA’s Jet Propulsion Laboratory (JPL), SPHEREx weighs approximately 500 kilograms and operates on 270 to 300 watts of power. It is fitted with a spectrophotometer capable of detecting 102 different wavelengths of light, which allows it to identify unique chemical signatures of molecules across space. James Fanson, Project Manager at JPL, told NPR that unexpected discoveries are likely to emerge from the mission’s data.

Accompanying Mission

As reported, SPHEREx will not be the sole payload on this launch. It will share the Falcon 9 with PUNCH (Polarimeter to Unify the Corona and Heliosphere), a NASA mission consisting of four satellites that will examine the sun’s outer atmosphere and solar wind dynamics. Together, these missions aim to deepen scientific knowledge of both the distant universe and the immediate solar environment.

New Study Suggests Dogs May Have Domesticated Themselves for Food

New Study Suggests Dogs May Have Domesticated Themselves for Food

The origins of dog domestication have been a topic of debate among scientists, with theories suggesting various evolutionary processes led to the transformation of wolves into the domestic dogs seen today. A new study has indicated that early wolves may have chosen to stay near humans due to the availability of food scraps, potentially leading to their domestication over thousands of years. The findings support the idea that self-domestication was possible through natural selection, as wolves that were more tolerant of human presence may have had better access to resources and, in turn, passed on these traits to their offspring.

Wolves and Their Path to Domestication

According to the study published in Proceedings of the Royal Society B, the first phase of dog domestication is believed to have taken place between 30,000 and 15,000 years ago. This period is thought to have been influenced primarily by natural selection rather than human intervention. Researchers suggest that wolves with a less aggressive temperament may have been more likely to stay near human settlements, where food was more accessible. Over time, these wolves may have selectively bred with others that exhibited similar traits, gradually leading to the emergence of early domesticated dogs.

The Role of Natural Selection

In an effort to address concerns regarding the timeframe of domestication, researchers used statistical models to determine whether natural selection alone could have driven this process. As per the findings, domestication through self-selection was plausible if two conditions were met: wolves had to opt for a human-proximate lifestyle due to consistent food availability, and they had to choose mates with a comparable level of tameness. Alex Capaldi, a mathematician and statistician at James Madison University, explained to Live Science that if both conditions were fulfilled, the timeline for self-domestication became feasible despite previous skepticism regarding the speed of such evolutionary changes.

Similar Patterns Observed in Other Animals

The study draws parallels with cat domestication, where felines are believed to have settled near human farming communities around 10,000 years ago. In exchange for hunting rodents, they gained access to human food resources, leading to a mutually beneficial relationship. Scientists suggest that understanding how domestication occurred in dogs may provide further insights into human-animal interactions throughout history, as dogs played a significant role in early human societies by assisting in hunting and herding.

Unanswered Questions in Dog Evolution

While the model presents a plausible explanation, researchers acknowledge that it does not definitively prove how domestication occurred. The study highlights self-domestication as a possibility rather than a confirmed mechanism. The debate over whether human intervention or natural selection played a greater role continues, with further research needed to uncover definitive answers. However, the findings contribute to a broader understanding of early human-animal relationships and how evolutionary forces shaped them.

NASA Partners With SpaceX To Launch NEO Surveyor

A contract has been awarded by NASA to SpaceX for the launch of its Near-Earth Object (NEO) Surveyor spacecraft, which is intended to identify asteroids and comets that could pose a threat to Earth. The mission is set to launch no earlier than September 2027 from Florida’s Space Coast using a Falcon 9 rocket. The contract for the launch and related services has been valued at approximately $100 million. The spacecraft is expected to enhance planetary defense efforts by detecting and characterizing near-Earth objects that could potentially cause significant damage upon impact. The mission will be operated by NASA’s Jet Propulsion Laboratory (JPL) in California, with support from various scientific institutions.

Mission Objectives and Capabilities

As per reports, according to NASA, the NEO Surveyor will be positioned at the Sun-Earth Lagrange Point 1, approximately 1.5 million kilometers from Earth. From this vantage point, the spacecraft will use its 50-centimetre infrared telescope to scan space in two infrared wavelengths. This will allow the detection of both bright and dark asteroids, including those that are difficult to observe with existing Earth-based telescopes. The goal of the mission is to locate at least two-thirds of undiscovered NEOs measuring 140 meters or more in diameter, which are large enough to cause regional devastation if they collide with Earth.

Planetary Defense Efforts and Previous Missions

The NEO Surveyor mission follows previous planetary defense initiatives involving SpaceX. In 2021, NASA’s Double Asteroid Redirection Test (DART) was launched aboard a Falcon 9 rocket, successfully impacting the asteroid Dimorphos to test the feasibility of altering an asteroid’s trajectory. In 2024, the European Space Agency’s Hera mission was also launched using a Falcon 9 to study the aftermath of the DART impact on the Didymos system. These missions are part of ongoing efforts to develop technologies capable of mitigating potential asteroid threats in the future.
