The IPO market is back, and it’s not the same companies leading the charge.

Dear Physics of the Cosmos (PhysCOS) community members-

As we prepare for our Ad ASTRA Community Science Workshop, we are writing to share important updates regarding the agenda structure and instructions for abstract submissions. 

The Community Science (Ad ASTRA) Workshop is organized by the NASA Astrophysics Division to engage the community in identifying future large, strategic astrophysics missions. Structured over three thematic days—Science, Capabilities and Implementation, and Community Discussion—the workshop provides a comprehensive framework to connect scientific priorities with technological readiness and mission implementation. Across all three days, plenaries, panels, breakout sessions, and poster contributions are designed to maximize community interactions and discussion. The outcomes of the workshop will help NASA prioritize mission concepts and shape a balanced, forward-looking astrophysics portfolio that is consistent with the Astro2020 recommendations and existing and future science gaps.

To best serve the community and facilitate meaningful collaboration, we are splitting the mission concept presentations into two distinct focuses: Science on Day 1, and Capabilities and Implementation on Day 2. We are relying on you—the concept teams and the broader community—to submit abstracts for both days. We are also offering the option to present mission concepts as posters, and will offer the opportunity to present as posters any abstracts for which there is insufficient room in the parallel sessions.

Please review the detailed agenda structure and submission guidelines below:

Day 1: Science Focus

• Science Questions: Day 1 will focus on open science priorities and questions from strategic documents (Astro 2020 Decadal Survey, Enduring Quests – Daring Visions from 2014) and more recent science questions that the mission concepts submitted to ASTRA will address. 
• Abstract Submission: Presentations for Day 1 are not restricted to mission concept team members. We strongly encourage other scientists in the community to submit abstracts presenting important science questions and to use this opportunity to connect with concept teams.
• Breakout Sessions: These sessions will be organized by science themes (Compact Objects and Energetic Phenomena, Cosmology, Galaxies, Exoplanets & Astrobiology, Stars and Stellar Populations). Moderators will present a summary of the panel discussions at the end of Day 1.

Day 2: Mission Concepts – Capabilities and Implementation

• Focus: Day 2 is focused on implementation, capabilities, and technologies (software and hardware) relevant to the ASTRA submitted mission concepts. A summary of the Innovation for Astrophysics Missions Workshop (May 2026) will inform discussions regarding industry and other capabilities and opportunities that may be leveraged. 
• Breakout Sessions: These sessions will be organized by capability groups, which will be determined once the submitted mission concept documents are reviewed.
• Format & Goals: Breakout sessions will feature a mix of presentations and flexible discussion. The goal is for teams with concepts at varying maturity levels to collaborate, find commonalities, and strengthen their respective capability groups.
• Abstract Submission Note: Teams may submit multiple abstracts for these sessions if their concept spans different capabilities (e.g., requiring both UV and X-ray technologies).

Day 3 & Workshop Outcome

A primary goal of this workshop is to refine a draft “science-to-capabilities” matrix, which will be built using inputs from your submitted ASTRA mission concept documents. During the Day 1 and 2 breakout sessions, moderators will capture key discussion points to present during end-of-day summary panels. On Day 3 of the workshop, we will hold a plenary discussion to recap the week and collaboratively revise the “science-to-capabilities” matrix. Together as a community, we will add, refine, and prioritize science questions, mapping them to mission concepts. 

Key Upcoming Dates:

• 24 June 2026: Abstract submission deadline (link). If you have already submitted an abstract and would like to modify it based on the guidelines above, please delete your previous contribution and send another submission. 
• 26 June 2026: Mission Concept Document submission deadline (template, submission portal)
• 10 July 2026: Contributed abstracts selected for talks and posters 

We look forward to your abstract submissions and to a highly collaborative and productive workshop! 

Best regards,

The Ad ASTRA Workshop Organizing Committee

The deci-Hertz Interferometer Space Antenna

Speaker

Jacob Slutsky, NASA / GSFC

Abstract

The origins and fate of massive compact objects such as black holes, neutron stars, and white dwarfs can only be fully answered by measuring deci-Hertz (dHz) gravitational wave emission. A plethora of innovative mission concepts have been proposed motivated by this need, promising incredible potential sensitivity and requiring substantial technical development. Like COBE rather than Plank, we optimize time to first knowledge over ultimate sensitivity. We describe the highest priority science goals contained in and motivating a dHz observatory, the minimum sensitivity required to make these observations, and the fastest, least-costly mission that meets these minimum requirements. We dub this mission the Deci-hertz Interferometer Space Antenna (DISA).

Apple Intelligence and Siri AI have sucked most of the oxygen out of the room at Apple's Worldwide Developers Conference this year—understandable, maybe, given that the AI-powered Siri delays are all anyone has wanted to ask any Apple executive about for the last two years.

But Apple Intelligence is just one of the three big focus areas Apple outlined during its keynote this week. The second is new parental controls—overdue, but promising-looking, as the parent of a 6-year-old with an iPad that I only begrudgingly connect to the Internet. And the third is "platform improvements," a catch-all for a wide range of fit-and-finish changes aimed at boosting responsiveness and addressing common user complaints.

I have the first beta of macOS 27 Golden Gate running on an M1 MacBook Air—the oldest, slowest hardware Apple supports now that Intel compatibility is out the window. With some help from Apple's densely packed wall-of-features slide, here are a few things from the "platform improvements" column I like the most, plus one item I'd still like to see.
