Perhaps we could start with that... I am not sure what you mean. We have had optical observations of at least one Einsten cross since the late 80s / early 90s[0, 1]. Signs of MACHOs were detected in 1995[2]. I don&amp;#x27;t know what a &amp;quot;GAI mapping mission&amp;quot; is, so I cannot comment on that.
