Why did NASA ram DART into an asteroid?

American space agency NASA recently conducted a planned mission to hit a cruising asteroid in space, as a part of its first planetary defense technology demonstration. Let's find out more about it

NASA's dress rehearsal: Spacecraft crashes into asteroid in defence test

A NASA spacecraft rammed an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth. The galactic grand slam occurred at a harmless asteroid 9.6 million kilometers away, with the spacecraft named Dart plowing into the small space rock at 22,500 kph. Scientists expected the impact to carve out a crater, hurl streams of rocks and dirt into space and, most importantly, alter the asteroid's orbit. Telescopes around the world and in space aimed at the same point in the sky to capture the spectacle. Though the impact was immediately obvious Dart's radio signal abruptly ceased it will be days or even weeks to determine how much the asteroid's path was changed. The USD 325 million mission was the first attempt to shift the position of an asteroid or any other natural object in space. "No, this is not a movie plot," NASA Administrator Bill Nelson tweeted earlier in the day. "We've all seen it on movies like Armageddon,' but the ...

NASA delays Artemis I launch for third time due to potential hurricane

NASA is skipping next week's launch attempt of its new moon rocket because of a tropical storm that's expected to become a major hurricane. It's the third delay in the past month for the lunar-orbiting test flight featuring mannequins but no astronauts, a follow-up to NASA's Apollo moon-landing programme of a half-century ago. Hydrogen fuel leaks and other technical issues caused the previous scrubs. Currently churning in the Caribbean, Tropical Storm Ian is expected to become a hurricane by Monday and slam into Florida's Gulf coast by Thursday. The entire state, however, is in the cone showing the probable path of the storm's center including NASA's Kennedy Space Centre. Given the forecast uncertainties, NASA decided Saturday to forgo Tuesday's planned launch attempt and instead prepare the 322-foot (98-metre) rocket for a possible return to its hangar. Managers will decide Sunday whether to haul it off the launch pad. If the rocket remains at the pad, NASA could try for an Oct

NASA again readies Artemis I Moon mission, troubleshoots hydrogen leak

The US space agency has once again readied its Artemis I moon mission and met all objectives, including the key hydrogen leak threat which has resulted in two failure attempts.

NASA's new moon rocket hit by fuel leaks in test ahead of final launch

NASA's new moon rocket sprouted more fuel leaks Wednesday in a test ahead of a possible launch attempt next week, but engineers managed to get them down to acceptable levels. There was no immediate word on whether NASA would try for a liftoff Tuesday given the sporadic nature of the hydrogen leaks, which have bedeviled the launch team for months. "Leaving a lot of folks scratching their heads on this one," said Launch Control's Derrol Nail. The daylong demo had barely begun when hazardous hydrogen fuel began escaping at the same place and same time as before, despite new seals and other repairs. Engineers halted the flow and warmed the lines in hopes of plugging the leak, and proceeded with the test. But the leak persisted before dropping to acceptable levels. Hours later, another leak cropped up elsewhere. Nail said all test objectives were met. But managers need to review the results before determining whether the 98-metre rocket is ready for its first test flight, a lunar-orbiti

Fuel leak disrupts NASA's second shot at launching moon rocket Artemis I

NASA's new moon rocket sprang another hazardous leak Saturday, as the launch team began fuelling it for liftoff on a test flight that must go well before astronauts climb aboard. For the second time this week, the launch team began loading nearly 1 million gallons of fuel into the 322-foot rocket, the most powerful ever built by NASA. Monday's attempt was halted by a bad engine sensor and leaking fuel. As the sun rose, an over-pressure alarm sounded and the tanking operation was briefly halted, but no damage occurred and the effort resumed, NASA's Launch Control reported. But minutes later, hydrogen fuel began leaking from the engine section at the bottom of the rocket. NASA halted the operation, while engineers scrambled to plug what was believed to be a gap around a seal. The countdown clocks continued ticking toward an afternoon liftoff; NASA had two hours Saturday to get the rocket off.
