The June 2018 news item in Science To find small asteroids that could hit Earth, private foundation embraces small satellites says:
On 10 May, B612 announced a partnership with York Space Systems, a Denver-based maker of standard 85-kilogram satellites, to investigate building a fleet of small asteroid hunters. [...] Now, B612 has developed a new technique to do the same thing at a far lower cost with small space telescopes. Ed Lu, B612's co-founder, expects the first telescope to cost about $10 million and believes a full constellation “would be a factor of many, many cheaper” than Sentinel.
Some asteroid astronomers are skeptical of the new approach, saying the technology is far from proven. “To be very, very blunt, what they are proposing and what they’ve demonstrated is not going to help us find more NEOs [near-Earth objects],” says astronomer Timothy Spahr, CEO of space consultancy firm NEO Sciences in Marlborough, Massachusetts, who does independent work for NASA.
Is it known what technology is described and how it is proposed to help identify a large number of near Earth asteroids?
Are there similarities with B612's Sentinel proposal, or is this something different? Would these be in LEO? Does that suggest they would not use thermal IR to identify the asteroids?
How would it compare to NeoCAM? (now NEO Surveyor)
