Planetary Defense
Monitoring of Near-Earth Objects
One of our main concerns in planetary defense is identifying and tracking near-Earth objects (NEOs) that could pose a threat to our planet. These objects include asteroids and comets that come within proximity to Earth’s orbit. By monitoring NEOs, we can better predict potential impacts and take appropriate measures to protect our planet.
There are several ways we monitor NEOs to gather essential data. Some of these methods are:
- Ground-based telescopes that detect and track the movement of NEOs
- Space-based infrared observatories that can identify objects not easily visible from Earth
- Collaboration with international agencies to share data and coordinate global efforts
Developing Mitigation Technologies
In addition to tracking NEOs, we also invest in the development of technologies that could help us mitigate the threat of an impact. Acting proactively in this regard bolsters our defense capabilities, and various options are being explored, such as:
- Kinetic impactors: These involve the use of spacecraft to collide with a threatening object at high velocity, altering its trajectory and steering it away from Earth.
- Gravity tractors: Here, a spacecraft hovers near a NEO and uses its gravitational pull to change the object’s course slowly.
- Deflection via nuclear devices: Though controversial, this method entails detonating a nuclear device near the NEO to change its direction without fragmenting it.
It is crucial that we advance our capabilities in both monitoring and mitigation as part of an effective planetary defense strategy to ensure the safety of Earth and its inhabitants.
Space Colonization and Human Settlement
Mars and Moon Colonies
The prospect of establishing colonies on Mars and the Moon has captivated our imagination for decades. Developing self-sufficient habitats on these celestial bodies would not only push the boundaries of our technological capabilities but also open up new opportunities for scientific research and economic growth.
Establishing a human presence on the Moon would allow us to:
