WASHINGTON — Scientists are ready to launch a spacecraft that will smash into a big asteroid to make it change its course away from Earth. Here are the details:
NASA reports that it’s ready to launch the first part of its planetary defense strategy on November 24, when it plans to launch the DART spacecraft.
The spacecraft will be launched on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
Once it gets into space, it will head for a pair of asteroids called the Didymos binary.
The spacecraft is expected to be in position to approach and smash into the smallest of the pair of asteroids by October 2, in 2022.
DART will impact the 160-meter-wide rock at around 21,700 kilometers per hour, nudging it very slightly, but enough to change its orbit slightly.
NASA will then measure the change in orbit and use it as very important data for future missions designed to protect Earth from large incoming meteors.
NASA previously announced on October 1 that the DART’s cube satellite was ready.
The miniaturized satellite will deploy 10 days before DART’s asteroid impact, providing essential footage of the collision and subsequent plume of materials.
NASA says DART will be the first demonstration of the kinetic impactor technique, which involves sending one or more large, high-speed spacecraft into the path of an asteroid in space to change its course and speed.

![Tonga Volcano Eruptions: Underwater Volcano Erupts, Triggering Tsunami Warnings
THE HUNGA-TONGA-HUNGA-HAAPAI VOLCANO, TONGA — The “once in 1,000 years” eruption of the Hunga-Tonga Hunga-Haapai[c] volcano on Saturday did not emerge from smaller volcanic cones as in previous eruptions in 2009 and across 2014 and 2015. Rather, it blasted out of a five-kilometer-wide underwater caldera, according to Shane Cronin, Professor of Earth Sciences at the University of Auckland.
The power of the explosion is likely because magma rose up from the caldera so quickly there was no time for a film of steam to form and allow the magma’s surface to cool as it passed through the water.
Instead, hot magma came into direct contact with cold water, creating explosions which split the magma up and forced it into further contact with additional cold water, causing additional explosions.
The resulting blast reached supersonic speeds, sending out a sonic boom that reached New Zealand, according to The Associated Press.
Unusually high waves drowned two people in Peru and caused widespread tsunami alerts elsewhere.
Damage to internet connections meant that very little news of the volcano’s impact on Tonga was available initially, though The Associated Press reported tsunami waves crashing across the shore and people rushing to higher ground.
Two smaller eruptions occurred at the same volcano on December 20 and January 13, and previous 1,000-year major caldera eruption episodes involved many separate explosion events, meaning several weeks or even years of major volcanic unrest could be due, according to Professor Cronin’s article on The Conversation.
In line with this reasoning, CNN reported on Monday that the volcano had erupted again, for the third time in four days, though unlike Saturday’s eruption, which was likely the biggest recorded anywhere on the planet in more than 30 years, there were no additional tsunami alerts.

![Ukraine’s Giant Bomb Shelter: Ukrainians Fleeing to Kyiv Metro System
KYIV, UKRAINE — As military experts warn that Russia may be shifting tactics, increasingly using artillery and air bombardments to ‘pulverize’ cities as they previously did in Chechnya and Syria, according to The Associated Press, Kyiv’s metro is operating as a citywide bomb shelter.
In the last week, Russia has bombarded Kyiv with missile strikes, with troops attempting to push into the city from the northwest and the Kyiv TV tower hit by a projectile on March 1.
The New Yorker explains that the situation is seeing metro stations in Kyiv fill with as many as 15,000 civilians every night in search of safety.
The system of 52 metro stations is home to famous historic features dating back to the Soviet era. Its Arsenalna [d]station is the deepest in the world at 105 meters below ground level.
