Due to the ongoing federal government shutdown (and uncertainty over when it will end), the EarthCube Office solicitation webinar originally scheduled for Friday, January 4, 2019 at 1 PM EST (and subsequently rescheduled for January 11), is now postponed indefinitely. A new webinar time will be announced after the government shutdown is over. Please stay tuned.
In the meantime, the EarthCube Leadership Council recommends interested bidders familiarize themselves with the guidance and background documents found here.
The full solicitation is here (NSF site).
