...composition to Murchison and Aguas Zarcas. Images returned from the spacecraft also look startlingly similar on a variety of scales. Here at The Open University, we are doing our part by studying Aguas Zarcas and other CMs to prepare for the samples that will be returned to Earth from what may be their ‘parent’ asteroids. We are using the element oxygen to study the...
