NASA’s DART Mission Tests Earth’s Defenses Against Asteroids | WSJ

The spacecraft crashed into an asteroid the size of the Washington Monument.

[@chea4007]

Agreed 👍

[@SevSeries-fi5ey]

A lot of people simply aren't aware of how high on the list of civilizational threats you can find asteroids. Most analysts put it in the top 5 or even top 3. Unfortunately we're squabbling over pronouns instead.

[@MVK_GS]

What I wonder is just how repeatable this would be in the future given advances due to this experiment. What I mean is that this specific asteroid has a certain composition, density, and orbit that affects how it responded to the impact. But I would imagine that the million, or so, asteroids that are now identified have their own variables that greatly affect how each of them would react to an impact. Thus, I wonder, just how much can we truly predict to build an effective countermeasure to avert an Earth impact? Nevertheless, this is truly amazing work by NASA and ESA.

why didn't they just add a detachable camera or something that could reanalyze the asteroid instead of making us wait another 4 years?

[@v1d300]

Ya slight shot away a sensor or camera 1000-2000 meters before collision. Would have been great. Also why the EU mission is to launch in 2024 for a reading in 2026? A few months after Dart launch would be more helpful isn't it?

[@bradenmcdorman8544]

Because DART was traveling at 14,000 miles an hour relative to the asteroid. You can't just detach a camera and have it stop next to the asteroid unless it has enough fuel to stop. 14,000 miles an hour is a lot of fuel.

[@v1d300]

@@bradenmcdorman8544 I did some more reading and WSJ didn't report this well in the video. But the LICIACube was integrated into the DART spacecraft inside a spring-loaded box placed on the wall of the DART spacecraft. It separated on 11 September, 2022 from DART by being ejected at roughly 4 km/h (2.5 mph) relative to DART, 15 days before impact. It will fly it past Dimorphos about 2 minutes 45 seconds after DART’s impact. So we shall soon start receiving small amounts of data over the period of few months.

They can't make satellites fly in space. When they send out a satellite they can't make it circuit back to earth. The moon landing is pong the videogame where you send a vessel between two planetary objects working as floorboards. For this reason launches need to be at certain days and precise. If they knew how to fly in space they could send them up every second no matter what day and fly to a planet but they can't. They have to predict when the floorboards hit the ball.

[@myke5696]

The Chixculub dinosaur killer was around 15 km wide. Not that big. Even though no such is headed towards us now, I don't think we know enough about all resonances that affect orbits out in the main belt to say such an asteroid could not head towards us in even 100 years. If so, I think the only chance of stopping this scenario would be deflection by a nuclear warhead. There wouldn't be enough time for multiple Dart kinetic impactors or a gravity tractor to work.

Thanks to geologists we think that all living beings on our planet Earth have the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. The Northern hemisphere is covered with a layer of ice that fell down "in blocks as great as mountains". These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
