    a Apophis is a near-Earth asteroid that caused a brief period of concern in December 2004, because initial observations indicated a probability of up to 2.7% that it would strike the Earth in 2029. Apophis broke the record for the highest level on the Torino Scale for asteroid impact hazard, being, for only a short time, at level 4, before it was lowered. On average, an asteroid the size of Apophis can be expected to impact Earth about every 80,000 years. Using more recent observations and calculations, the threat of impact from Apophis in the years 2029 and 2036 has been eliminated. However, astronomers and mission planners continue to monitor the asteroid to calculate potential future close encounters. 

    Challenge Description:

    Develop a mission concept to explore Apophis to better predict its orbital dynamics and to instrument the object with a radio transponder prior to the 2029 close approach.

    Functional Specifications:

    A short high-level preliminary mission concept report. The report would include a summary mission description, proposed instrumentation, and potential spacecraft and launch vehicle options or baseline.

    • avoiding asteroids

      our project is based on a prototype-probe that we invented and that we are going to send on Apophis. if it is successful, it can be used on other asteroids too. the prototype will be launched by means of a space rocket Arion 5 directed towards the asteroid. Upon landing, the probe will clasp to t... Visit Project

    • Infrared Asteroid Swarm

      This project proposes to not only tag and track Apophis, that happens to be on a high-risk orbit, but find other, smaller ones with also a significant threat, but which we humans don't know yet. The proposal contains a mission description of affordable, open-source cubesats (the parallel chal... Visit Project

      Tener un modelo en el cual se represente las condiciones aproximadas para mandar un transpondedor en orbita junto al asteroide Apophis y asi tener una manera mas de recibir señal y tener mas informacion acerca de ese peligro. Visit Project

    • Radioisotope Thermoelectric Asteroid Triangulation

      Through this brief proposal, we are attempting to create and illustrate a generalized platform for tracking speed, position, and orbit of the Apophis asteroid using a limited number of base function active transponders. We believe, after significant consideration, that an active signal being bro... Visit Project
