    As scientific meetings are canceled worldwide, researchers are rethinking how they network a move that should have done earlier. “At some point, we need to be having conversations about ‘What is the point of a conference now? says Sarah Horst, a planetary scientist.

Meeting spaces that are inaccessible to some disabled scientists, health considerations, a lack of access to childcare and travel restrictions can all encl up alienating potential attendees from physical conferences. There’s a large appetite” for alternative conference set-ups, says Divya Persaud, a planetary scientist. She and Eleanor Armstrong, a UCL sociologist of space science, have a grant from their university to hold an experimental virtual conference, called Space Science in Context, in May. The conference aims to improve accessibility. Participants will watch recorded talks ahead of time and then join in online conversations on the day of the conference. Persaud says that the response to plans for the meeting, which launched its save-the-date website last week, has been overwhelmingly positive. But she also points out that many of the adjustments that conferences are making, such as introducing virtual participation, are accommodations for which disabled scientists have been demanding loudly for years, and it’s a shame that it took a global health crisis to make them happen.

Still, as conference organizers are finding out, making these changes, especially on short notice, is no easy thing. The European Geophysical Union (EGU) general conference is scheduled for 3---8 May in Vienna, and session leaders are making other plans in case it is canceled. Those intending to participate in the Lunar and Planetary Science Conference this week in The Woodlands, Texas, found that they are trying to come up with alternative solutions when that conference was canceled on 4 March. Most of the responses were just ‘ Well , have the conference online’ “ says Horst.
