Asteroid deflection technologies

Asteroid deflection technologies are methods and strategies developed to prevent potential impacts of asteroids with Earth. These technologies aim to alter the trajectory of an asteroid to ensure it does not collide with our planet Following the success of NASA's DART (Double Asteroid Redirection Test) mission, discussions about planetary defense and asteroid deflection strategies are increasingly prominent. Here are some principal methods and how they work: 1. Kinetic Impactor:    - How It Works: This method involves sending a spacecraft to collide with an asteroid at high speed. The impact changes the asteroid's velocity and trajectory, ideally enough to avoid a collision with Earth.    - Example: NASA's DART (Double Asteroid Redirection Test) mission successfully demonstrated this technique by impacting the moonlet Dimorphos in 2022. 2. Gravity Tractor:    - How It Works: A spacecraft positioned near an asteroid uses its gravitational pull to...

SpaceX's Starship Super-Rocket

Elon Musk Takes the Long View in Glitzy Update on SpaceX's Starship Super-Rocket

SpaceX CEO Elon Musk finally gave us an update on how the development of the Starship and Super Heavy booster is going. During a presentation at the SpaceX Starbase facility in Boca Chica, Texas, Musk showed off a fully stacked up Starship and Super Heavy booster. He said the company is waiting on approval from the FAA and other government agencies to give them the green light to launch the spacecraft sometime in the next few months.

During the presentation, he talked about the challenges of developing the Raptor 2 engine (it tries to melt its combustion chamber) and the plans to construct a second Starbase at Cape Canaveral in Florida. Attendees were also able to see the enormous Mechazilla launch tower, which will catch incoming rockets with its chopstick arms.
