Ich habe gerade einen Artikel für das IEEE -Spektrum geschrieben (https://spectrum.ieee.org/planetary-defense-killer-asteroids) über meine Arbeit an einigen großen Fragen: Ist die Menschheit durch potenziell tödliche Asteroidenauswirkungen in Gefahr? Wie können wir sie erkennen? Und wie können wir uns schützen?
Ich arbeite bei den Johns Hopkins Applied Physics Laboratory, das Raumschiffe entwirft, das sich in Asteroiden stürzen kann, um zu verhindern, dass sie die Erde treffen.
Ich habe seit Jahren Asteroiden recherchiert. Ich war Instrumentenwissenschaftler für das Mercury Dual Imaging System (MDIS) und Vorsitzender der Geologie -Disziplin -Gruppe für die Messenger -Mission der NASA. Ich war in fünf Feldteams mit dem ANSMET -Programm (Antarctic Search for Meteorites). Und Asteroid 6899, Nancychabot, ist nach mir benannt.

Ich werde von Andy Rivkin, einem Experten für Asteroiden und Planetenverteidigung, begleitet, um sicherzustellen, dass wir alle Ihre Fragen beantworten können.
Wir werden zwei Stunden von 13 bis 15 Uhr ET am 12. Juni hier sein.
Nachweisen:
I’m planetary scientist Nancy Chabot, and I study the formation of rocky objects in space, including asteroids that might hit Earth. Ask Me Anything!

How realistic is it that we’ll be mining asteroids in the next 100 years?
I have read that there are some asteroids that are more dense than they are supposed to be, and some people theorize it could be due to an undiscovered natural element with an extremely high atomic weight. I was wondering if these asteroids do indeed exist, and if so is that simply a fringe theory or are some scientists taking it seriously?
Isn’t the the whole entirety of everything in the universe dependent upon gravity? You said anything
Was specific software developed to reduce satellite „noise“ from interfering with asteroid detection, or was it discovered not to be an issue?
If we discovered a large asteroid heading toward Earth within 5 years notice, what would the best mitigation strategy be?
Thank you, Nancy, and Andy, for taking the time to answer our questions today!
Your article mentioned that a big challenge from the recent NASA/FEMA exercise was how hard it is to quickly send a spacecraft to get a closer look at a threatening asteroid. From your personal experience facilitating that exercise, what was the most surprising or impactful technical detail you learned about how ready (or not ready) we are to respond quickly, especially when dealing with a fast-moving object like 2024 YR4? How has that insight changed your personal priorities for future missions?
Thanks again for all your amazing work!
1. When I first read your AMA post, I thought it said that your name was Nancy Chatbot. Has anyone ever made that mistake before?
2. How will the cuts to NASA’s budget affect our ability to study potential asteroid threats to the earth?
How will the proposed federal budget cuts to NASA and NSF affect your research, if any? Or your colleagues‘ research fields?
Do we ever see asteroids that fly directly at us from outside the solar system? As in, asteroids that don’t orbit the sun? If so, how would we prepare for them?
It seems like the current detection plan involves observing when an asteroid flies near us, then calculating when/where it will do so again.
I don’t think any sizable asteroid will hit our planet or cause sizable damage to the humanity in near future. Why? Is it because universe is expanding and all objects are getting far and far away from each other?
What is the protocol you would follow if you detected an asteroid likely to impact Earth that is too big to alter its course with spacecraft crashing?
