NASA spaceship deflected asteroid in test to save Earth

NASA on Tuesday said it had succeeded in deflecting an asteroid in a historic test of humanity’s ability to stop an incoming cosmic object from devastating life on Earth.
The fridge-sized Double Asteroid Redirection Test (DART) impactor deliberately smashed into the moonlet asteroid Dimorphos on September 26, pushing it into a smaller, faster orbit around its big brother Didymos, said NASA chief Bill Nelson.
“DART shortened the 11 hour 55 minute orbit to 11 hours and 23 minutes,” he said. Speeding up Dimorphos’ orbital period by 32 minutes exceeded NASA’s own expectation of 10 minutes.
“We showed the world that NASA is serious as a defender of this planet,” added Nelson.
The asteroid pair loop together around our Sun every 2.1 years, and pose no threat to our planet.
But they are ideal for studying the “kinetic impact” method of planetary defense, in case an actual approaching object is ever detected.
DART’s success as a proof-of-concept has made a reality of science fiction — notably in films such as “Armageddon” and “Don’t Look Up.”
Astronomers rejoiced in stunning images of matter spreading out thousands of miles in the wake of the impact — pictures collected by Earth and space telescopes, as well as a mini satellite that had traveled to the zone with DART.
Pseudo-comet
Thanks to its temporary new tail, Dimorphos, which is 530-foot (160-meter) in diameter or roughly the size of a big Egyptian pyramid, has turned into a manmade comet.
But quantifying just how well the test worked required an analysis of light patterns from ground telescopes, which took a few weeks to become apparent.
The binary asteroid system, which was around 6.8 million miles (11 million kilometers) from Earth at impact, is visible only as a single dot from the ground.
Ahead of the test, NASA scientists said the results of the experiment would reveal whether the asteroid is a solid rock, or more like a “rubbish pile” of boulders bound by mutual gravity.
If an asteroid is more solid, the momentum imparted by a spaceship will be limited. But if it is “fluffy” and significant mass is pushed at high velocity in the opposite direction to impact, there will be an additional boost.
Never actually photographed before, Dimorphos appeared as a speck of light around an hour before impact.
Its egg-like shape and craggy, boulder-dotted surface finally came into clear view in the last few moments, as DART raced toward it at roughly 14,500 miles (23,500 kilometers) per hour.
Mass extinction
Very few of the billions of asteroids and comets in our solar system are considered potentially hazardous to our planet, and none are expected in the next hundred years or so.
But wait long enough, and it will happen.
The geological record shows, for example, that a six-mile wide asteroid struck Earth 66 million years ago, plunging the world into a long winter that led to the mass extinction of the dinosaurs along with 75 percent of all species.
An asteroid the size of Dimorphos, by contrast, would only cause a regional impact, such as devastating a city.
Kinetic impact with a spaceship is just one way to defend the planet, albeit the only method possible with current technology.
Should an approaching object be detected early, a spaceship could be sent to fly alongside it for long enough to divert its path via using the ship’s gravitational pull, creating a so-called gravity tractor.
Another option would be launching nuclear explosives to redirect or destroy an asteroid.
NASA believes the best way to deploy such weapons would be at a distance, to impart force without blowing the asteroid to smithereens, which could further imperil Earth.

Trump appoints Stallone, Voight, and Gibson as special ambassadors to Hollywood
U.S. President-elect Donald Trump announced on Thursday the appointment of actors Sylvester Stallone (‘Rocky’) and Jon Voight (‘Midnight Cowboy’), as well as actor and director Mel Gibson (‘Braveheart’) as special ambassadors to the “very problematic” Hollywood.
“They will help me as special envoys to make Hollywood, which has lost many overseas businesses in the last four years, COME BACK BIGGER, BETTER, AND STRONGER THAN EVER,” he posted on his social media platform, Truth Social.
The Republican lamented all the “problems” he claims Hollywood faces and created this role with the aim of improving the situation from a business perspective.
“These three talented men will be my eyes and ears. I will do whatever they suggest,” he said.
Stallone had previously described Trump as the second George Washington, the first U.S. president (1789–1797) and one of the nation’s founding fathers, during a dinner after his victory in the November presidential elections, where he served as the master of ceremonies.
Meanwhile, Gibson attacked Trump’s rival, Vice President Kamala Harris, accusing her of having “the IQ of a fence.”
The Republican leader will be sworn in as president on January 20 on the steps of the U.S. Capitol, succeeding Democrat Joe Biden.

Latin American and Caribbean diplomats voice concern over U.S. mass deportation plan
Diplomatic chiefs from ten Latin American and Caribbean countries expressed their “serious concern” over the announcement of a mass deportation of migrants, a measure they consider incompatible with human rights, according to a joint statement released this Friday.
The statement, which does not attribute the measure to any specific country, refers to the announcement made by U.S. President-elect Donald Trump, who has promised to carry out the largest foreign deportation operation in the history of the nation once he takes office next Monday. “The announcements of mass deportations are a serious cause for concern, especially due to their incompatibility with the fundamental principles of human rights and their failure to effectively address the structural causes of migration,” the statement said, released by Mexico’s Ministry of Foreign Affairs (SRE).
The signing countries—Brazil, Belize, Colombia, Cuba, El Salvador, Guatemala, Haiti, Honduras, Mexico, and Venezuela (almost all migrant-sending nations)—also committed to “defend the human rights of all migrants.”
This includes “rejecting the criminalization of migrants at all stages of the migration cycle” and “protecting them as a priority from transnational organized crime that profits from migration,” the document adds.

Noboa once again entrusts the Vice President of Ecuador to the vice president he appointed by decree
The President of Ecuador, Daniel Noboa, returned this Thursday to delegate – for the second time – the Presidency to the Secretary of Public Administration and Cabinet of the Presidency Cynthia Gellibert, whom he himself appointed by decree vice president in charge, in the face of the open confrontation he maintains with the vice president, Verónica Abad.
As he did last week, Noboa again issued a decree in which he announces that he is absent from the Presidency from Thursday to Sunday, to make an electoral campaign in search of his re-election in the elections of February 9, and during that period of time it will be Gellibert who will be in charge of the head of the State.
This action of the president of Ecuador is a matter of evaluation by the ordinary and constitutional justice at the request of the vice president, Verónica Abad, who claims to assume the presidential functions during the full period of the electoral campaign, in which according to the Constitution the head of state must ask for leave for being a candidate for re-election.
In his decree, Noboa argues that, although the Constitution determines that the Vice Presidency must assume the head of State in the event of the absence of the president, this “is not limited to the elected vice-president, but to the person who to date is exercising the functions of the Vice Presidency.”
Before appointing Gellibert as vice president in charge by decree, Noboa sent Abad to the Ecuadorian Embassy in Turkey, after a judge annulled the five-month suspension that the same Government had imposed on him. Until now, the vice president remains in Ecuador to claim to be the one who temporarily assumes the Presidency.
The new period of Gellibert with presidential powers began at 18:00 local time (23:00 GMT) this Thursday and is scheduled to end at 22:00 (03:00 GMT) next Sunday, time at which the debate between presidential candidates is expected to end where Noboa is summoned to participate.
After the debate, Noboa plans to travel to Washington to attend Donald Trump’s presidential inauguration, according to the Ecuadorian Presidency.
After the first assignment of the Presidency to Gellibert, Abad denounced a “coup d’état” and urged the Organization of American States (OAS) to apply the Democratic Charter, considering that the constitutional order had been broken because it had not received the presidential powers, as contemplated in the Ecuadorian Constitution.
In addition, he filed a protection action with which he seeks that the Justice annul the decrees in which Noboa appointed Gellibert as vice president in charge and delegated the Presidency to him. A court admitted the appeal on Friday, but did not accept some precautionary measures that Abad also asked for to suspend those effects immediately.
Controversies like this will be part of the analysis and evaluation of the electoral observation mission (EOM) of the European Union (EU) for the Ecuadorian elections, as anticipated on Wednesday by its leader, Spanish MEP Gabriel Mato.
The confrontation between Noboa and Abad began in the electoral campaign for the second round of elections for the extraordinary elections of 2023, and was reflected when he assumed the charges, when in one of his first decisions, the president sent the vice president to Israel as ambassador, with the mission of seeking peace between Israelis and Palestinians.
Abad has denounced Noboa for alleged political gender violence and has accused her of leading a harassment against her to force her to resign and thus avoid having to delegate the Presidency to her during the electoral campaign period, which runs from January 5 to February 6.
The titular vice president has also accused the Government of being behind the corruption investigation in the offices of the Vice Presidency that involves her son in a case where the Prosecutor’s Office also sought to indict Abad, but the National Assembly (Parliament) voted mostly against lifting the jurisdiction, although the ruling party voted in favor.
The general elections in Ecuador are called for Sunday, February 9 and, according to the polls published so far, Noboa and the candidate of the correismo Luisa González appear as prominent favorites to move on to the second round.
