8–10 September, 2020, UTC

A 48-hour international collaboration & co-working event focused on NASA's TESS Mission.

Structure & program

This is a working meeting in the style of a hack week or sprint and there won't be any talks. Instead, the goal is to encourage participants to work together to learn something new, meet people with complementary skills, and create something useful (in the form of a software package, a paper, an idea, or something else that we haven't thought of yet).

The specific schedule of the program is still being developed, but the time will be mostly unstructured and participants will not be expected to participate outside of their usual working hours. In advance, participants asynchronously introduce themselves and pitch project ideas to the rest of the group. Then, we will self-organize into groups, split up the work, and collaborate on the project for the two days of the program. At the end, all participants will asynchronously share what they learned or achieved with the rest of the group.

We are working to develop a schedule and a set of project management recommendations to encourage and support collaborations across time zones. But, this is also an experiment, so all participants are encouraged to join with an open mind, enthusiasm about building new collaborations, and a willingness to change plans if (when) things don't proceed as expected.


If you publish a paper that benefitted from this workshop, we request you follow the collaboration policy and include the following statment in your acknowledgement:

This project was developed in part at the meeting, which took place globally in 2020 September.

Collaboration policy

To ensure transparency and openness, we have adopted the collaboration policy developed for the Gaia Sprints. This policy requires that participants agree to the following:

All participants will be expected to openly share their ideas, expertise, code, and interim results. Project development will proceed out in the open, among participants and in the world.

Participants will be encouraged to change gears, start new collaborations, and combine projects. Any participant who contributes significantly to a project can expect co-authorship on resulting scientific papers, and any participant who gets significant contributions to a project is expected to include those contributors as co-authors.

These rules make it inadvisable to bring proprietary data sets or proprietary code, unless the participant bringing such assets has the rights to open them or add collaborators.

Code of conduct

We are dedicated to providing a harassment-free conference experience for everyone, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or technology choices. We do not tolerate harassment, abusive behavior, or intimidation of conference participants in any form. As such, we follow the AAS Code of Ethics, and expect all participants to read and abide by the statements in the AAS Code of Ethics.
