02.12.27 The groups at IOTA and IONIC have commissioned a new three-way beam combiner for imaging with phase-closure data. The new beam combiner greatly improves the sensitivity for imaging, allowing a new and exciting program of imaging protoplanetary environments with sub-astronomical unit resolution. The commissioning team for the December observing run included Jean-Philippe Berger, Fabien Malbet, Rafael Millan-Gabet, and John Monnier. See the news release IOTA/IONIC: YSOs with Three Telescopes.

02.12.19 Scientists at TNO TPD Space Department in The Netherlands successfully completed a test program on their Achromatic Phase Shifter. A deep and stable broadband null has been achieved in the visible waveband, which would be equivalent to a null of 100,000 in the IR, sufficient for planet detection. The Nulling breadboard contract awarded by ESA to the team comprising Astrium Space, Germany, TNO TPD, The Netherlands and the Technical University of Vienna has entered the final performance testing phase. Last month TNO TPD has completed their part of the test program. A deep broadband null of 36,000 in the Near Infrared has been obtained. During the next couple of months further comparative tests will be carried out by Astrium Space using different source simulator and phase shifter concepts. (Contributed by Fred Kamphues, TNO TPD).
02.12.18 The European Southern Observatory has issued the press release New Vistas Open with MIDI at the VLT Interferometer announcing first fringes with MIDI using the two 8.2-m telescopes ANTU and MELIPAL, 15 December 2002. Fringes were first obtained at 8.7 microns with Epsilon Carinae with a baseline of 102 m.

02.12.11 The SMART-2 mission proposed by the European Space Agency was to be shared by LISA and Darwin. The mission had originally two spacecrafts and was to be used by Darwin as a technology precursor mission for formation flying. The mission will now have only a single spacecraft and be devoted solely to LISA. The SMART-3 mission, although yet to be confirmed, will very likely be for Darwin only and pursue the technology program that was to be conducted for SMART-2. SMART-3 may have three spacecraft and include a stellar interferometer. It is currently scheduled for launch in 2008-2009. (Courtesy of Malcolm Fridlund.)
02.12.11 Alain Leger has been awarded the European Space Agency's achromatic phase shifter contract for Darwin.

A number of working groups have already been established.
02.03.05 The technology testbed for StarLight (also previously known as ST-3, and DS-3) has passed one of its most significant milestones by actively tracking white-light fringes. This event is reported at the Planet Quest website. The testbed interferometer had first acquired white-light fringes in late January 2002, and began actively tracking fringes by February 20. Plots of delay as a function of time are also available through the Planet Quest News Release.

02.02.25 At 1:30 am Friday 23 February 2002 IOTA achieved three-telescope phase-closure for the first time. See the news release page at the IOTA web site. For one of the baselines it was the first time that fringes had been obtained with that telescope pair. IONIC, the integrated optic combiner from Grenoble was used to obtain the fringes. With fringes on two baselines, the third one came in within a wavelength of the others. Also see the plot of first fringes. (Courtesy of Rafael Millan-Gabet).
02.02.25 The 2002 PTI Call for Proposals has been issued. The call for proposals is principally intended for members of the PTI collaboration, but is also included as a link on the PTI home page. The call, written by Andy Boden of Caltech's Interferometry Science Center, offers interesting insights to the current status and future prospects of PTI. Most notably, "the current ISC plans call for this observing season [2002] to be the last full guaranteed observing season of V2 operation with PTI." The decision has not yet been made to allocate funds for PTI for 2003, and it is possible the interferometer will cease observing at the end of this year.
