The CHEOPS Time Allocation Committee (TAC) met on 11 - 13 May 2022 to review proposals submitted to the third and final annual Announcement of Opportunity (AO-3) for observing time in ESA's CHEOPS Guest Observers Programme during the nominal mission.

The third annual announcement of opportunity (AO-3) for participation in the CHEOPS Guest Observers Programme was due to open on 9 November 2021. The AO has been postponed and is currently foreseen to come out in early 2022.

While exploring two exoplanets in a bright nearby star system, ESA's exoplanet-hunting CHEOPS satellite has unexpectedly spotted the system's third known planet crossing the face of the star. This transit reveals exciting details about a rare planet "with no known equivalent", say the researchers.

EnVision will be ESA's next Venus orbiter, providing a holistic view of the planet from its inner core to upper atmosphere to determine how and why Venus and Earth evolved so differently.

Key technology for ESA's exoplanet-hunting PLATO spacecraft has passed a trial by vacuum to prove the mission will work as planned. This test replica of an 80-cm high, 12-cm aperture camera spent 17 days inside a thermal vacuum chamber.

Observing time on CHEOPS in the Guest Observers Programme has been awarded to nine proposals received in response to the CHEOPS second Announcement of Opportunity (AO-2).

ESA's exoplanet mission CHEOPS has revealed a unique planetary system consisting of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star. The sizes and masses of the planets, however, don't follow such an orderly pattern.

The optical and infrared instruments of Euclid, ESA's mission to study dark energy and dark matter in space, have passed their qualification and acceptance reviews and are now fully integrated into the spacecraft's payload module.

ESA's exoplanet mission Ariel, scheduled for launch in 2029, has moved from study to implementation phase, following which an industrial contractor will be selected to build the spacecraft.

Proposals are solicited in response to the second Announcement of Opportunity (AO-2) for observing time in the CHEOPS Guest Observers Programme. This AO covers the period 26 March 2021 to 25 March 2022. The deadline for proposals is 1 December 2020, 13:00 CET/12:00 GMT.

The European Space Agency (ESA) and the Japanese Aerospace Exploration Agency's Institute of Space and Astronautical Science (ISAS/JAXA) have announced their decision to no longer consider the infrared space observatory, SPICA, as a candidate for the upcoming selection as ESA's 5^th medium-class mission in its Cosmic Vision...

ESA's Science Programme Committee has confirmed the continued operations of five missions led by ESA's Science Programme: Cluster, Gaia, INTEGRAL, Mars Express, and XMM-Newton, from 1 January 2021 to 31 December 2022. The SPC also confirmed the Science Programme's contributions to the extended operations of Hinode, Hubble Space Telescope,...

ESA has released its first Solar Orbiter data to the scientific community and the wider public. The instruments contributing to this data release come from the suite of in-situ instruments that measure the conditions surrounding the spacecraft.

Proposals are invited for the CHEOPS Discretionary Programme, an element of the Guest Observers Programme which enables scientists to propose observations of individual targets that have been discovered, or declared to be of high scientific merit, since the close of AO-1 back in mid-May 2019.

The first images from Solar Orbiter, a new Sun-observing mission by ESA and NASA, have revealed omnipresent miniature solar flares, dubbed 'campfires', near the surface of our closest star.

ESA's Euclid mission has reached another milestone on its journey towards launch. Its two instruments are now built and fully tested. These have been delivered to Airbus Defence and Space in Toulouse, France, where they are now being integrated with the telescope to form the mission's payload module.

CHEOPS, ESA's new exoplanet mission, has successfully completed its almost three months of in-orbit commissioning, exceeding expectations for its performance.

First measurements by a Solar Orbiter science instrument reached the ground on Thursday, providing a confirmation to the international science teams that the magnetometer on board is in a good shape following a successful deployment of the spacecraft's instrument boom.

ESA's Solar Orbiter mission lifted off on an Atlas V 411 from Cape Canaveral, Florida, at 05:03 CET on 10 February on its mission to study the Sun from new perspectives.

Six weeks after the launch of CHEOPS, ESA's Characterising Exoplanet Satellite, the telescope cover was opened as part of the mission's in-orbit commissioning.
