Astrobiology as science has numerous challenges. We list here the challenges for which we would like contributors of this special issue to address: Definition of life; Origins of life: what came first, genetic material, such as RNA, or proteins; Origins of chirality in the biochemical molecules; Problems in functioning of the biomolecules which do not have proper chirality or have a mixed chirality; Viruses and the origins of life; Viroids and subviral particles: are they close to the RNA world; The RNA world: is it a result of a genetic takeover from a simpler system; Evolution of life: punctuated equilibria, graduated equilibria; Catastrophic events on Early Earth: did they destroy the original life; Chemistry on meteorites and asteroids: what does it tell us about the extraterrestrial chemical possibilities; Did life arise on the Earth several times; Future of life on Earth: what will happen when Sun heats up; Extraterrestrial life: is it similar to ours; Planetary protection: are we doing a good job; Protection of Earth as the host for life on Earth: are we doing a good job; Biogeomarkers identification; and Habitability: from microbes to humans.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Challenges is an international peer-reviewed Open Access biannual journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
