Welcome one and all to a new edition of Inside Space. The List of the 100 Most Essential Twitter Accounts in Space is finally coming together and you can find it here. So far, I've included high-profile science communicators, space organizations, journalists, astronauts and rocket company executives. I need your help to continue adding people and to make the list more diverse so please send me your recommendations by replying to this email. A big "THANK YOU" to the many readers that have already done so!
