NASA launches spacecraft to deflect asteroid from collision with Earth

A spacecraft that must ultimately crash to succeed was launched late on Tuesday from California on a NASA mission to demonstrate the world’s first planetary defense system, designed to deflect an asteroid from a potential doomsday collision with Earth.

The DART spacecraft soared into the night sky at 10:21 p.m. Pacific time on Tuesday (1:21 a.m. Eastern/0621 GMT Wednesday) from Vandenberg US Space Force Base, about 150 miles northwest of Los Angeles, carried aboard a SpaceX-owned Falcon 9 rocket.

The launch was shown live on NASA TV.
The DART payload, about the size of a small car, was released from the booster minutes after launch to begin a 10-month journey into deep space, some 6.8 million miles (11 km) from Earth.
Once there DART will test its ability to alter an asteroid’s trajectory with sheer kinetic force, plowing into it at high speed to nudge the space boulder off course just enough to keep our planet out of harm’s way.
Cameras mounted on the impactor and on a briefcase-sized mini-spacecraft to be released from DART about 10 days beforehand will record the collision and beam images of it back to Earth.
The asteroid DART is aimed at poses no actual threat and is tiny compared with the cataclysmic Chicxulub asteroid that struck Earth some 66 million years ago, leading to extinction of the dinosaurs. But scientists say smaller asteroids are far more common and pose a greater theoretical danger in the near term.
DART’s target is an asteroid “moonlet” the size of a football stadium that orbits a chunk of rock five times larger in a binary asteroid system named Didymos, the Greek word for twin.
The team behind DART, short for Double Asteroid Redirection Test, chose the Didymos system because its relative proximity to Earth and dual-asteroid configuration make it ideal for observing the results of the impact.

Bumping asteroid moonlet

The plan is to fly the DART spacecraft directly into the moonlet, called Dimorphos, at 15,000 miles per hour (24,000 kph), bumping it hard enough to shift its orbital track around the larger asteroid.
Cameras on the impactor and on a briefcase-sized mini-spacecraft released from DART about 10 days beforehand will record the collision and beam images back to Earth. Ground-based telescopes will measure how much the moonlet’s orbit around Didymos changes.
The DART team expects to shorten Dimorphos’ orbital track by 10 minutes but would consider at least 73 seconds a success. A small nudge to an asteroid millions of miles away would be sufficient to safely reroute it.
DART is the latest of several NASA missions of recent years to explore and interact with asteroids, primordial rocky remnants from the solar system’s formation 4.6 billion years ago.
Last month, NASA launched a probe on a voyage to the Trojan asteroid clusters orbiting near Jupiter, while the grab-and-go spacecraft OSIRES-REx is on its way back to Earth with a sample collected last October from the asteroid Bennu.
The Dimorphos moonlet is one of the smallest astronomical objects to receive a permanent name and is one of 27,500 known near-Earth asteroids of all sizes tracked by NASA.
Although all none poses a foreseeable hazard to humankind, NASA estimates many more asteroids remain undetected in the near-Earth vicinity.
The DART spacecraft, cube-shaped with two rectangular solar arrays, is due to rendezvous with the Didymos-Dimorphos pair in late September 2022.
NASA put the entire cost of the DART project at $330 million, well below that of many of the space agency’s most ambitious science missions.

Arabian Saluki Beauty Contest at ADIHEX 2024: A celebration of ancestral elegance

The Abu Dhabi International Hunting and Equestrian Exhibition (ADIHEX) announce the return of the prestigious Arabian Saluki Beauty Contest, a unique initiative aimed at highlighting the significance of purebred hunting dogs and fostering a connection between the new generation and their rich ancestral heritage.
Under the esteemed patronage of H.H. Sheikh Hamdan bin Zayed Al Nahyan, Ruler’s Representative in Al Dhafra Region and Chairman of the Emirates Falconers’ Club (EFC), this iconic event is scheduled from 31st August to 8th September, 2024, at ADNEC Centre Abu Dhabi, celebrating the blending of deep Emirati cultural traditions with cutting-edge innovation and technology across 11 diverse sectors.
A highlight of this year’s event is the Arabian Saluki Beauty Contest. One of the world’s oldest and most revered dog breeds, the Arabian Saluki stands as a symbol of wild hunting and desert traditions in the Middle East. Known for its grace, speed, and intelligence, this distinctive breed has been a faithful companion to the Bedouin people for over 5,000 years, serving as both a hunter and guardian. The Saluki’s agility and loyalty have made it an integral part of hunting and racing traditions, especially within the Arabian Peninsula.
The Arabian Saluki Centre was established in Abu Dhabi in 2001 alongside the Emirates Falconers’ Club, marking the first facility of its kind in the Arabian Gulf region and the Middle East, to revive the tradition of desert hunting using Saluki dogs, a cherished aspect of desert heritage.
ADIHEX was the first cultural event in the Arab region to honour the bond between Man and his loyal companion, which has been by our side for thousands of years. The Arabian Saluki Beauty Contest is a unique initiative designed to promote interest in purebred hunting dogs and to strengthen the new generation’s connection to their ancestral heritage and traditions and to serve as a testament to this unique bond.
With its origin steeped in history, this fascinating dog’s name is believed to be derived from the city of Saluk in Yemen or the Bani Saluk tribe. Renowned for its endurance and elegance, the Saluki can reach speeds up to 75 kilometres per hour, maintaining this pace over distances up to almost five kilometres. The breed is cherished for its unique physical characteristics, including a slender body, deep chest, long legs, and two distinct coat types: ‘Al Hoss’ (smooth) and ‘Aryash’ (feathery).
The Arabian Saluki Beauty Contest, held during ADIHEX, is more than a beauty pageant. It celebrates the essence of the Saluki by focusing on the dog’s personality, skills, reflexes, and sensory response. Unlike typical dog competitions, this contest evaluates the Saluki’s breed characteristics, behaviour, overall appearance, structure, hunting skills, and psychological traits. Judging criteria include the dog’s gait, head, eyes, mouth, ears, coat, colour, and general impression.
The Arabian Saluki Beauty Contest is an integral part of ADIHEX’s mission to preserve and promote the cultural heritage of the UAE and the wider Arab world. This contest not only showcases the beauty and abilities of the Saluki but also plays a vital role in raising awareness about the importance of preserving traditional hunting practices and the Saluki’s role in them.
This year’s competition will feature four categories: ‘Smooth (Hoss) Males,’ ‘Feathery (Aryash) Males,’ ‘Smooth (Hoss) Females,’ and ‘Feathery (Aryash) Females.’ The event is scheduled to take place during ADIHEX 2024, and, per the rules, participants must ensure their dogs are healthy, microchipped, and vaccinated.
The Saluki’s enduring legacy is celebrated through this competition, which draws participants and spectators from across the region and beyond. It provides a platform for Saluki enthusiasts to connect, share their passion, and celebrate a breed that has remained virtually unchanged for millennia, reflecting the diverse hunting landscapes and traditions of the Middle East.
Aside from the alluring Arabian Saluki Beauty Contest, as the largest edition of ADIHEX to date, the 21st edition will showcase thousands of brands across 11 diverse sectors, offering a dynamic platform for new business opportunities and captivating audiences of all ages. This exhibition celebrates the thrill of an adventurous outdoor lifestyle, allowing visitors to explore falconry, hunting, equestrian sports, veterinary products, fishing and marine sports, environmental preservation, cultural heritage, arts and crafts, and the latest in technology and innovation across all the represented sectors.
