He is an elected member of the International Academy of Astronautics, a Fellow of the British Interplanetary Society, and a member of the Science Fiction and Fantasy Writers of America, the National Space Society, and MENSA. Publisher’s Weekly noted that “The spirit of Arthur C. Clarke and his contemporaries is alive and well…” when describing Les’s 2018 novel, Mission to Methone. His 2018 non-fiction book, with co-author Joe Meany, Graphene: The Superstrong, Superthin, and Superversatile Material That Will Revolutionize the World was reviewed in the journal Nature and excerpted in American Scientist. His latest anthology, Stellaris: People of the Stars, was published by Baen Books in September 2019. In his day job, Les is a Principal Investigator of two interplanetary solar sail space missions at the NASA Marshall Space Flight Center. The first, Near Earth Asteroid Scout, scheduled for spaceflight in 2021, will use a 925 square foot solar sail to propel a small spacecraft to rendezvous with an asteroid. The second, Solar Cruiser, will demonstrate the ability of an 18,000 square foot solar sail-propelled spacecraft to perform scientific observations of the sun when it flies in 2025.
