NASA’s unprecedented asteroid-deflection mission is more than ‘billiards in space,’ scientists say ...

The hope is that the collision will nudge Dimorphos into a closer orbit around its 780-meter partner, Didymos, shortening its nearly 12-hour orbital period by a few minutes.

The answer, which should be revealed from the crater and ejecta produced by DART's collision, could determine just how hard to hit an asteroid when the exercise is not a test.

Untold riches from Asteroid mining- The problem no one is talking about | Tech News

Asteroid mining could unlock untold riches and thorny ethical problems. Are we ready as we race to the launch pad? Asteroid mining is coming sooner than people realise. Several asteroid mining companies have developed serious business cases.

The most enthusiastic advocates of asteroid mining suggest it could unlock trillions of dollars of wealth; more sober analysts: tens of billions.

DART section lead available to discuss upcoming asteroid impact experiment

On Sept. 26, the international community will watch as NASA’s latest spacecraft collides with an asteroid in an attempt to knock it off its orbit.

Cristina Thomas, an assistant professor of astronomy and planetary sciences at Northern Arizona University and lead of the DART Observations Working Group, has spent the nine months since the DART mission launch collecting data from the ground and waiting for the historic moment of ...

Your impact: September equinox 2022 | The Planetary Society

One of The Planetary Society's core enterprises is planetary defense against asteroid impacts. Your support keeps this essential work going strong.

In May, Society leaders participated in an international conference titled "Apophis T-7 Years: Knowledge Opportunities for the Science of Planetary Defense," which dealt with preparations for the close approach of asteroid Apophis in 2029.

Alabama engineers wait to "sail" to an asteroid | Alabama Public Radio

NASA is targeting later this month for another launch try for its new Artemis moon rocket. The spacecraft which is managed, designed, and tested at Alabama's Marshall Space Flight Center has been plagued with hydrogen leaks. Engineers will try to fix the problem at the launch pad.

"This will open the capability for other small spacecraft to use this kind of propulsion, which for small spacecraft gives you more total propulsion than any another system that packed in such a small volume."

NASA spacecraft set to intentionally crash into an asteroid to help save Earth

SpaceX provided a ride into space for NASA's DART mission, the first attempt to test out an Earth protection plan from asteroids by crashing a spacecraft into one.

NASA will use a spacecraft later this month to test a planetary-defense method that could one day save Earth.

Wasp 'drill' inspires asteroid surface sampler and microsurgery probe

Insects are a source of versatility, ideas and concepts. Every insect is encased within a layer of cuticle, a fibrous composite. Without much variation in density or chemistry, its modulus ranges across seven orders of magnitude.

Years later I was again interested in making holes – this time it was wasps (not the garden stingers) drilling holes in wood to lay their eggs.
