20/04/2017 Gaia celebrates its 1000th day in routine phase

Today Gaia celebrates its 1000th day in routine phase. After the launch on 19 December 2013 and the six-month long in-orbit commissioning period, the routine scientific operations phase started on 25 July 2014.

Since then, Gaia gathered more than 35 TB of data and observed close to 70 billion transits. Thanks to all Gaia DPAC and ESA Gaia people for their enthusiasm and dedication to Gaia! Find more mission numbers here.

03/02/2017 Gaia DR2 Schedule

The schedule leading up to Gaia DR2 (Data Release 2) has recently been revisited by the DPAC project office, together with ESA. Some necessary changes in the data processing, together with an improved data processing flow, have led to a revised schedule which is believed to be firm as it is based on true performance testing and availability analysis of hardware and people. The new release date will be April 2018. Further details are available here.

25/01/2017 Vacancy: Post-doctoral fellowship at IMCCE/Paris Observatory

A postdoc position "Gaia astrometry and physical properties of asteroids" is available at the IMCCE/Paris Observatory related to the scientific exploitation and validation of Gaia data on asteroids. This fellowship is intended for a period of 18 months, with a possible extension depending on funding and performance. The application deadline is 1 March 2017 with a start date before 1 June 2017. The position will remain open until fulfilled. More information can be found here.

24/01/2017 Gaia’s contribution to asteroid science

Just now ESA Science&Technology published an article on the contribution Gaia has on asteroid science. Tests of the software to detect asteroids in the Gaia data were successful. A Gaia Follow-Up Network for Solar System Objects is in place in case a suspected asteroid is spotted. More information on the Solar System Alerts can be found here.

19/12/2016 Happy 3rd birthday to Gaia!

Since the launch of Gaia on 19 December 2013 Gaia performed an impressive number of astrometric, photometric and spectroscopic measurements. More than 60 billion times an object moved through the Gaia focal plane. The total amount of science data collected since launch can now be viewed through a new information page on mission status numbers.

18/11/2016 Gaia16aye is getting brighter

The spectacular binary microlensing event, Gaia16aye, is getting brighter just as predicted in the Image of the Week item of 27 October. The peak of the brightening is expected on 21 or 22 November and should reach about 11 magnitude in l-band. We are very lucky as the next observation of this target by Gaia happens to be right in time for this brightening and will happen on 21 November (as predicted using GOST).

An extensive follow-up campaign is conducted, according to Lukasz Wyrzykowski. You can contact him if you would like to be involved or if you want to share some data with him on this expected brightening.  The current model, including astrometric prediction, is available here.

This AMA session will highlight day-to-day operations performed for Gaia. If you ever wanted to know more about how well the spacecraft is performing, how commands are sent up to the satellite or what the orbit of Gaia looks like, this is the moment to ask. Our operations team will be happy to answer your questions.

24/08/2016 A Very Human Venture: Personal Perspectives on Gaia's Data Processing and Analysis Consortium

Since its launch in December 2013 Gaia has been sweeping the skies mapping around one billion stars. The data collected will allow astronomers to probe the very nature of the astronomical objects observed by the spacecraft. But before the data can be useful to the scientific community they must pass through a complex and robust processing pipeline. This is the story of how that pipeline was created and how it has struggled and thrived by virtue of being a truly human endeavour. To read the whole piece, click here.

16/08/2016 Gaia's second anniversary marked by successes and challenges

Despite a series of unexpected technical challenges, the mission is on track to complete the most detailed and complex mapping of the heavens ever undertaken. The first mission data will be released on 14 September 2016. Read the whole story here.
