W marcu lub kwietniu po zaobrobawaniu zmian w projekcie planowane jest przejście do Fazy B projektu.
Trwają też zabiegi dotyczące międzynarodowej współpracy.

(...) Hertz said that, under the project’s current schedule, there will be a system requirements review and mission design review in February, followed by an independent cost assessment. That will be followed by the Key Decision Point B review in March or April, which would allow the project to proceed into Phase B of its development. (...)

Najnowsza wersja budżetu NASA na rok fiskalny 2019 zaproponowana przez Prezydenta USA znosi finansowanie teleskopu WFIRST:

Terminates a New Space Telescope while Increasing Support for other Astrophysics Priorities. The Budget terminates development of the WFIRST space telescope, which was not executable within its previous budget and would have required a significant funding increase in 2019 and future years. The Budget redirects funding from this mission to competed research including smaller, principal-investigator-led astrophysics missions. These
missions have a history of providing high scientific impact while training the next generation of scientists
and engineers. The Budget continues to fund the $8.8 billion James

To byłoby dość śmieszne z tym teleskopem... Leży na Ziemi, nie ma pieniędzy, by go użyć! :(

Zobaczymy - mysle ze ostateczna propozycja budzetu jeszcze sie mocno zmieni. Pamiętajmy że to okres wielu przepychanek i tu środowisko naukowe nie odpuści (za to odpusci Europa Landera)

Pomimo propozycji anulowania misji trwają prace nad redukcją kosztów teleskopu.
Przewidywane zwiększenie budżetu WEBB-a może odbyć się kosztem misji astrofizycznych.

WFIRST work continues despite budget and schedule uncertainty
by Jeff Foust — March 28, 2018

(...) The biggest change, he said, is turning the other WFIRST instrument, a coronagraph, into solely a technology demonstration. “The direction to us was that we were being too ambitious” by adding science requirements to the instrument that informed its design, he said. “That had impacts in a lot of areas.” (...)

Podpisano kontrakt na Short Wave Infra-Red Sensor Chip Assembly (SCA)

NASA Awards the Short Wave Infra-Red Sensor Chip Assembly for WFIRST
CONTRACT RELEASE C18-011 (Goddard) June 15, 2018

NASA has awarded a contract to Teledyne Scientific & Imaging, LLC, Camarillo, California, for the Short Wave Infra-Red Sensor Chip Assembly (SCA) for the Wide Field Infrared Survey Telescope (WFIRST) Project.

Managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, WFIRST is fully-funded for Fiscal Year 2018. Work will continue on the mission in this time period until appropriations for Fiscal Year 2019 have been determined.

The contract is a Cost-Plus-Award-Fee contract with a value of $23,035,123. The period of performance is from June 14, 2018, through Oct. 31, 2020.

The contract shall provide 72 Short Wave Infrared SCA devices for the WFIRST Space Flight Focal Plane Assembly. In addition, the contractor shall perform a Warm Functional Test and Cold Functional Screen Test for final space flight SCA testing and performance requirements verification.

Trwają zmagania polityczne o utrzymanie projektu.
Misja HST za kilka lat dobiegnie końca, a WEBB ma przewidziany tylko kilkuletni okres działania.

Senator seeks assurances on JWST and WFIRST funding
by Jeff Foust — November 20, 2018

(...) Van Hollen, in his letter, raised concerns about budget pressures on WFIRST that could arise from the need for additional JWST funding. “As you know, the overall cost of WFIRST is highly dependent on the phasing of the project, so to minimize costs, the project’s current funding profile must be maintained so that technical risk can be resolved on long-lead items and major contracts executed to begin work on the bus and other major components,” he wrote.

Van Hollen does have some local interest in keeping JWST and WFIRST on track. The lead center for both missions is the Goddard Space Flight Center in Maryland. JWST science operations will be handled by the Space Telescope Science Institute, also located in Maryland. (...)

Final fiscal year 2019 budget bill secures $21.5 billion for NASA
by Jeff Foust — February 17, 2019

(...) The bill also retains funding for the Wide-Field Infrared Survey Telescope (WFIRST), which NASA sought to cancel in its 2019 budget request. The $321 million provided is intended to keep the mission on track for a launch in the mid-2020s, with a cost cap of $3.2 billion. (...)

WFIRST faces funding crunch
by Jeff Foust — March 28, 2019

WASHINGTON — A NASA astrophysics mission that avoided cancellation last year could still face budget problems if it evades another termination threat this year, agency officials warned this week.

NASA’s fiscal year 2020 budget request includes no funding for the Wide Field Infrared Survey Telescope (WFIRST), the next large strategic, or flagship, astrophysics mission for the agency after the James Webb Space Telescope. NASA, in its request, said that it proposed cancelling the mission because of “its significant cost and higher priorities within NASA, including completing the delayed James Webb Space Telescope.”

WFIRST was the top-ranked flagship mission in the latest astrophysics decadal survey, published in 2010. The spacecraft, featuring a 2.4-meter primary mirror provided to NASA by the National Reconnaissance Office, is designed to carry out research ranging from exoplanets to dark matter and dark energy. The mission, currently cost-capped at $3.2 billion, is scheduled for launch in 2025.

At a March 27 hearing of the commerce, justice and science subcommittee of the House Appropriations Committee, Rep. José Serrano (D-N.Y.), chairman of the subcommittee, asked NASA Administrator Jim Bridenstine about the proposed cancellation of WFIRST, noting the ability of WFIRST to work in concert with JWST. “If one was built to work with the other, why is WFIRST considered for elimination?” he asked.

Bridenstine pointed out the cost and schedule overruns of JWST. “We’re now getting it back on track,” he said. “If James Webb isn’t yet ready, preparing WFIRST right away is probably not the right approach.” He emphasized the importance of having a portfolio of both large and smaller missions.

He suggested WFIRST could be revived once JWST is launched. “WFIRST will be a critical mission when James Webb is on orbit,” he said. (...)
