CAPE CANAVERAL, FLORIDA – SpaceX launched a rescue mission for the two trapped astronauts at the International Space Station on Saturday, sending up a smaller crew to bring them home, but only until next year.

The capsule launched into orbit to retrieve the test pilots, whose Boeing aircraft had returned to Earth empty earlier this month due to safety concerns. The change in rides required NASA’s Nick Hague and Russia’s Alexander Gorbunov to retrieve Butch Wilmore and Suni Williams.

Because NASA rotates space station crews every six months, this recently launched spacecraft, which has two vacant seats allocated for Wilmore and Williams, will not return until late February. Officials claimed there was no way to bring them back sooner on SpaceX without disrupting other scheduled operations.

SpaceX Launches Rescue Mission For 2 NASA Astronauts Who Are Stuck In Space Until Next Year

By the time they return, the two will have spent over eight months in space. They signed up for Boeing’s first astronaut journey, which launched in June, expecting to be gone for only a week.

NASA ultimately judged that Boeing’s Starliner was too risky after a series of thruster problems and helium leaks hampered its journey to the orbiting complex. The space agency removed two astronauts from this SpaceX mission to create room on the Dragon capsule’s return leg for Wilmore and Williams.

According to NASA deputy program manager Dina Contella, Wilmore and Williams observed the liftoff via a live link broadcast to the space station, causing Williams to scream “Go Dragon!”.

Williams has been appointed to commander of the space station, which will soon return to its normal crew of seven. Once Hague and Gorbunov arrive on Sunday, the four astronauts who have been there since March will be able to leave in their own SpaceX capsule. Starliner’s problems caused a month-long delay in their return home.

Hague stated before the trip that change is the one constant in human spaceflight.

“There is always something that changes. “Maybe this time it was more visible to the public,” he explained.

Hague was appointed commander of the rescue mission based on his experience and handling of a launch incident six years prior. The Russian rocket failed shortly after takeoff, and the capsule holding him and a cosmonaut was propelled off the top to safety.

Rookie NASA astronaut Zena Cardman and veteran space flier Stephanie Wilson were removed from this journey after NASA decided to work with SpaceX to bring the trapped astronauts home. Both promised a future space voyage and were there at NASA’s Kennedy Space Centre to watch the launch live. Gorbunov remained aboard the voyage as part of a NASA-Russian Space Agency exchange agreement.

“Every crewed launch that I’ve ever seen has made me quite emotional. “This one today was especially unique,” a teary-eyed Cardman said after the early afternoon launch. “It was hard not to watch that rocket lift off without thinking, ‘That’s my rocket and that’s my crew.'”

Moments before liftoff, Hague paid tribute to his two colleagues who were left behind, saying, “Unbreakable. “We did it together.” Once in orbit, he referred to it as a “sweet ride” and expressed gratitude to everyone who made it possible.

Previously, Hague acknowledged the difficulties of launching with half a crew and returning with two astronauts trained on another spacecraft.

“We’ve got a dynamic challenge ahead of us,” Hague stated after returning from Houston last weekend. “We know each other and we’re professionals and we step up and do what’s asked of us.”

SpaceX has long been at the forefront of NASA’s commercial crew program, which began more than a decade ago while the space shuttles were being retired. In 2020, SpaceX outperformed Boeing in terms of astronaut delivery to the space station, and NASA now has ten crew trips scheduled.

Boeing has struggled with a number of challenges over the years, including repeating a Starliner test flight with no one on board after the original one went off course. The Starliner that left Wilmore and Williams in space landed safely in the New Mexico desert on September 6 and has since returned to the Kennedy Space Centre. Boeing removed its defence and space chief a week ago.

The latest SpaceX liftoff, delayed by Hurricane Helene battering Florida, was the first for astronauts from Cape Canaveral Space Force Station’s Launch Complex 40. SpaceX took over the old Titan rocket pad nearly two decades ago and utilised it for satellite and station cargo launches, as well as flying people from Kennedy’s older Apollo and shuttle pads next door. As the number of Falcon rockets increased, the firm desired greater flexibility.

Australia Asks Residents to Catch Deadly Funnel Web Spider

Australia, funnel web spider

As summer approaches in Australia, residents are warned to look out for the funnel web spider, one of the country’s deadliest species.

In addition to advising the public to avoid funnel-web spiders during mating season, the Australian Reptile Park in New South Wales has even asked people to capture live funnel-web spiders so they can “milk” their venom.

Native to eastern Australia, the funnel web spider can kill humans in as little as fifteen minutes if they do not receive medical treatment for its poisonous bite.

There have been thirteen fatalities attributable to this species, but none since the development of antivenom in 1981. The Australian Reptile Park is appealing to the public for assistance capturing and donating spiders, as the serum relies on milking live spiders.

Hunting for the funnel net spider in residential areas is common practice after a particularly wet and warm season. Look for spiders in cool, dark places like pools, garden residue, heaps of dirty clothing, and outside shoes.

Australian Reptile Park spider keeper Emma Teni recently blogged about how they rely on spider donations more than ever, especially now that breeding season has arrived and the temperature is perfect.

“Male funnel-web spiders have short lifespans, and with approximately 150 spiders required to make just one vial of antivenom, we need the public’s help to ensure we have enough venom to meet demand.”

“If you spot an egg sac while collecting a spider, it’s important to safely collect that as well,” said Teni. “It can provide a robust supply of healthy young spiders to aid in our antivenom production.”

The spiders won’t be able to climb plastic or glass, but Teni suggests capturing funnel webs in a wide-mouthed jar with a cover. Then, you can lead the spiders into the container using a long spoon or something similar.

After that, fill the jar with moist soil, screw on the top, and bring it to the designated drop-off spot.

“We depend on the public for spider donations, and we want to make sure everyone stays safe during the collection process, especially with conditions being so favourable this year,” said Teni.

A Spacecraft Is On Its Way To A Harmless Asteroid Slammed By NASA In A Previous Save-The-Earth Test

Published

CAPE CANAVERAL, Florida – A spacecraft launched Monday to probe the site of a cosmic accident.

The European Space Agency’s Hera spacecraft launched on a two-year trip to the little, harmless asteroid slammed by NASA two years ago as a practice run for the day when a murderous space rock threatens Earth. It’s the second phase of a planetary defense experiment that could one day save the globe.

SpaceX’s Falcon rocket vanished with Hera into the late morning clouds. An hour later, cheering erupted in the control center in Germany as the spacecraft split from the rocket’s upper stage and returned home. “It’s an amazing day,” the space agency’s director general, Josef Aschbacher, said later.

The 2022 crash of NASA’s Dart spacecraft reduced Dimorphos’ orbit around its larger companion, indicating that if a harmful rock was heading our way, it might be pushed off course with adequate warning.

Scientists are eager to analyze the aftermath of the impact up close to determine how effective Dart was and what improvements may be required to protect Earth in the future.

“The more detail we can glean the better as it may be important for planning a future deflection mission should one be needed,” University of Maryland astronomer Derek Richardson stated before launch.

Researchers want to know if Dart (short for Double Asteroid Redirection Test) created a crater or changed the 500-foot (150-meter) asteroid more dramatically. It seemed to be a flying saucer before Dart’s blow and may now resemble a kidney bean, according to Richardson, who participated in the Dart mission and is assisting Hera.

Dart’s wallop sent rubble and boulders hurtling off Dimorphos, adding to the impact’s momentum. For months, the debris track extended thousands of miles (almost 10,000 kilometers) into space.

According to flight director Ignacio Tanco, some rocks and debris may still be hovering about the asteroid, posing a threat to Hera.

“We don’t really know very well the environment in which we are going to operate,” Tanco informed me. “But that’s the whole point of the mission is to go there and find out.”

European authorities refer to the $400 million (363 million euros) effort as a “crash scene investigation.”

“Hera is going back to the crime scene and getting all the scientific and technical information,” said project manager Ian Carnelli.

Carrying a dozen science instruments, the compact car-sized Hera must swing past Mars in 2025 for a gravitational boost before landing at Dimorphos by the end of 2026. It’s a moonlet of Didymos, the Greek word for twin, a five-times larger asteroid that spins quickly. At that point, the asteroids will be 120 million miles (195 million kilometers) from Earth.

Hera will attempt to enter orbit around the rocky duo, progressively reducing flyby distances from 18 miles (30 kilometers) to a half-mile (1 kilometer). The spacecraft will examine the moonlet for at least six months to determine its mass, shape, composition, and orbit around Didymos.

Before the crash, Dimorphos circled its larger partner from three-quarters of a mile (1,189 meters) away. Scientists believe the orbit has become tighter and more oval-shaped, and that the moonlet may be tumbling.

Two shoebox-sized Cubesats will launch from Hera for even closer drone-like examinations, with one employing radar to peek beneath the moonlet’s boulder-strewn surface. Scientists believe Dimorphos was produced from particles shed by Didymos. The radar measurements should assist in determining whether Didymos is the small moon’s parent.

After their survey, the CubeSats will attempt to land on the moonlet. If the moonlet tumbles, the situation will become more complicated. Hera may potentially conclude its mission with a perilous touchdown but on the bigger Didymos.

Neither asteroid poses a threat to Earth, before or after Dart appeared. That is why NASA chose the pair for humanity’s first asteroid-deflecting demonstration.

Asteroids, which are remnants of the solar system’s origin 4.6 billion years ago, circle the sun principally between Mars and Jupiter in what is known as the main asteroid belt, where millions of them live. When they fall from the belt and land in our area, they become near-Earth objects.

NASA now has around 36,000 near-Earth objects, the majority of which are asteroids, although there are also some comets. More than 2,400 of them are deemed potentially dangerous to the Earth.

NEW YORK — Prepare to spot a rare and dazzling comet.

The space rock is hurling toward Earth from the far reaches of the solar system and will make its closest approach on Saturday. It should be visible through the end of October, assuming clear skies.

A Rare Comet Brightens The Night Skies In October

Comet Tsuchinshan-Atlas should be visible to the naked eye, but binoculars and telescopes will provide a clearer view.

“It’ll be this fuzzy circle with a long tail stretching away from it,” explained Sally Brummel, planetarium manager at the Bell Museum in Minnesota.

What is a comet?
They are frozen remains from billions of years ago when the solar system was formed. They heat up as they swing toward the sun, revealing their distinctive streaming tails.

In 2023, a green one that had last visited Earth 50,000 years ago flew past again. Other significant flybys were Neowise in 2020 and Hale-Bopp and Hyakutake in the mid to late 1990s.

Where did Tsuchinshan-Atlas come from?
Also known as C/2023 A3, was found last year and named after the observatories in China and South Africa that spotted it.

It originated in the Oort Cloud, which extends far beyond Pluto. After making its closest approach to Earth at 44 million miles (71 million kilometers), it will not return for another 80,000 years, provided it survives the journey.

Every year, several comets are detected, but many of them burn up near the sun or are too far away to be observed without special equipment, according to Larry Denneau, a key researcher with the Atlas telescope that helped discover it.

How to View

Those seeking to see Tsuchinshan-Atlas should go outside about an hour after sunset on a clear night and look to the west.

The comet should be visible from both the Northern and Southern Hemispheres.
