WASHINGTON– NASA wishes to keep the costs of extra delays in the James Webb Space Telescope within the program’s existing reserves and therefore avoid asking Congress for extra financing.

At a June 24 conference of NASA’s Astrophysics Advisory Committee, Eric Smith, program scientist for JWST at NASA Head office, stated that while a brand-new target launch date for the huge area telescope hasn’t been identified yet, the firm anticipated that the costs connected with that slip will be covered by existing monetary reserves.

” The program has fiscal reserves, in addition to the schedule reserves, and right now we do not anticipate needing extra financing since we have money to spend for additional time in the schedule,” he stated.

JWST exhausted its schedule reserve due to the fact that of the downturn in work triggered by the coronavirus pandemic. Thomas Zurbuchen, NASA associate administrator for science, said June 10 that because of that downturn, the objective will not make its March 2021 launch date

Smith stated NASA anticipates to set a brand-new launch date in July after completing evaluations, including taking a look at how modifications in work treatments required by social distancing protocols impact the staying activities. “What has changed is the efficiency in which those tasks can be finished,” he stated. That might consist of, he said, adding more schedule reserve beyond the two months that the program had in March.

He did not approximate just how much the launch date will slip, but it is most likely to be at least a couple of months. Before the pandemic slowed work on JWST, NASA was preparing to put the telescope through a last series of acoustics and vibration tests in May and June. Smith stated those tests are now arranged for August.

Smith declined to say just how much budget plan reserve the objective has remaining. “We can go a couple of months, several months past the March [2021] date and still have reserves to cover that,” he stated.

JWST has an expense cap of $8.8 billion set by Congress after the objective’s previous schedule slip in2018 Set up overruns alone don’t require congressional approval, Smith said, however boost that exceed the cap would require reauthorization.

SOFIA cancels Southern Hemisphere project

Another NASA astrophysics mission impacted by the pandemic, the Stratospheric Observatory for Infrared Astronomy (SOFIA), has canceled a prepared release of the airborne observatory to New Zealand due to the fact that of the pandemic.

In a June 23 presentation at the committee meeting, Naseem Rangwala, SOFIA job scientist, said the project worked for weeks on a way to perform that observing campaign within the limitations imposed by the pandemic, but ultimately concluded it was not possible.

” The logistical, personnel and travel-related difficulties remained, and we made a very hard decision to cancel the 2020 New Zealand deployment,” she stated. The project has for several years carried out such implementations, generally in the Northern Hemisphere summer season, to conduct observations of celestial objects visible just from Southern Hemisphere skies.

She said the job worked with the New Zealand federal government and the U.S. Embassy in New Zealand on ways to perform the campaign offered the country’s restrictions on global travel, including a 14- day quarantine on any arrivals. Those restrictions have actually gotten rid of COVID-19 in the country, but eventually were excessive to conquer for SOFIA.

SOFIA, a Boeing 747 equipped with a 2.5-meter infrared telescope, has actually been grounded since March because of safety constraints enforced in action to the pandemic. Earlier this month, job officials expressed optimism about resuming flights as quickly as late June

Those plans, which will require the approval of NASA, are still being developed, Rangwala said, using some of the preparation that entered into the canceled New Zealand project. “The project established comprehensive plans and protocols for how to safely operate SOFIA within COVID-19 constraints,” she stated.

She said the job now intends to resume flights in mid-July from California. “We are making very good progress on getting the observatory went back to science flights,” she said.

SOFIA’s shutdown throughout the pandemic comes as the mission deals with the risk of cancellation in the company’s 2021 budget proposition, in addition to efforts to improve the performance and scientific output of the observatory. That has included canceling an instrument that was under development for SOFIA called the High Resolution Mid-infrared Spectrometer, or HIRMES.

” The HIRMES project was over-budget and over-schedule,” said Paul Hertz, director of NASA’s astrophysics department, at the conference. “They had unsolved innovation problems and might not produce a credible plan to finish within a predictable amount of cash, so we terminated the task for its overruns.”

Deal with HIRMES-related technology will continue, he stated, but will be funded by a technology development program and not the SOFIA project.
