  SKA-Low Opens Science Verification at AA2

  SKA ObservatoryMurchison Radio-astronomy Observatory, Western Australia, Australia

  开始于 2027/06/30预估可信度 63%280天后SKAO's^[1] own science-operations timeline puts SKA-Low's AA2 Science Verification at 2027, and the observatory has said verification is offered with AA2 in the first half of that year; with no day announced the pin takes the end of the stated window.

  The SKA's low-frequency telescope in Western Australia reaches its AA2 array assembly in 2027, the stage at which science verification observations begin.

  SKA-Mid Opens Science Verification at AA2

  SKA ObservatoryKaroo, Northern Cape, South Africa

  开始于 2029/12/31预估可信度 70%3.3年后SKAO's^[1][2] own SKA-Mid science-operations timeline places AA2 and the start of Science Verification at 2029, with AA* following in 2031. Only the year is given, so the pin takes the last day of 2029.

  The SKA's mid-frequency array in South Africa's Karoo reaches AA2 in 2029, two years after its Australian counterpart, opening science verification observations.

  Euclid Releases the Foundation of Its First Data Release

  European Space Astronomy Centre, Camino Bajo del Castillo, Sexmo de Casarrubios, El Castillo, Comunidad de Ciudad y Tierra de Segovia, Villanueva de la Cañada, Community of Madrid, 28692, SpainEuropean Space Agency

  

  开始于 2026/11/30预估可信度 72%68天后ESA's^[1][2] DR1 timeline page, updated 15 June 2026, gives DR1-Foundation as "November 2026" and the complete DR1 as mid-2027, and says exact release dates will be provided later. A month with no day is estimated at that month's last day, which puts this pin on 30 November 2026; it moves when ESA names the day.

  The first stage of Euclid Data Release 1 puts out all raw data and calibrated images, catalogues and spectra over about 1,900 square degrees of sky. The higher-level products for galaxy clustering and weak lensing follow in mid-2027.

  Rubin Observatory Delivers Its First LSST Data Release

  Vera C. Rubin ObservatoryVera C. Rubin Observatory, Cerro Pachón, Chile

  开始于 2028/06/30预估可信度 68%1.8年后Rubin's early-science plan gives the LSST^[1] start as 2026-06-29 and says processing one year of data "is estimated to require approximately one year", which "implies an expected DR1 delivery approximately two years after the effective start" - while warning the boundaries are set by "survey performance and scientific readiness rather than a fixed calendar date".

  Rubin's Data Release 1, built from the first year of the Legacy Survey of Space and Time, is expected about two years after the survey began on 29 June 2026.

  LIGO, Virgo and KAGRA Begin the IR1 Observing Run

  NSF LIGO - Hanford, 127124, North Route 10, Richland, Benton County, Washington, 99354, United StatesLIGO

  

  开始于 2026/11/15预估可信度 68%53天后The collaborations' own observing plan, last updated 3 September 2026, gives only a window - a six-month run "beginning early- to mid-November of 2026" - and says the next update is due 15 October 2026 or sooner. With no day named, the pin takes the close of the stated window rather than its start, so it is not early; it moves when the collaborations name the day.^[1]

  The gravitational-wave detectors start a six-month intermediate observing run before the fifth observing run. Both LIGO detectors take part, Virgo joins despite possible maintenance interruptions, and KAGRA joins as it becomes available.
