Ongoing: the EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects (https://indico.esa.int/event/530). Step one in “Planetary Defense” is, of course, to spot the Potentially Hazardous Objects (PHOs). But step two is also important: gauge the size of the threat object.… Read More »Workshop: Size Determination of Potentially Hazardous NEOs

The RAMSES mission is (unofficially) going forward. The prime contractor, OHB Italia, has been awarded funding– many millions of Euros. RAMSES, if you aren’t in the loop, is a mission to scout out potentially-hazardous asteroid (PHA) 99942 Apophis before its… Read More »RAMSES’ important figure
Yes, an incoming impactor was detected before impact. Object 2024 UQ was spotted (by the ATLAS telescope system) and reported back to the NEOCP (the Minor Planet Center‘s Confirmation Page). A trajectory solution determined that the object was likely to… Read More »Pre-detection of Impacting Meteor 2024 UQ
