Redesign of Planned Space Telescope Would Add Scientific Capabilities, Costs to Original Mission

"However, the inherited hardware was designed for another purpose, and the degree to which changes to the hardware must be made to accommodate a different launch vehicle and scientific requirements is uncertain at this time. This uncertainty contributes to higher technical risk and a greater likelihood that costs will increase beyond current estimates, the report says. The WFIRST/AFTA without the coronagraph was estimated to cost $2.1 billion, up from an estimate of $1.8 billion for an earlier design which was more similar to the mission recommended in the 2010 survey report."

First Direct Evidence of Cosmic Inflation, HSCFSA

"Researchers from the BICEP2 collaboration today announced the first direct evidence for this cosmic inflation. Their data also represent the first images of gravitational waves, or ripples in space-time. These waves have been described as the "first tremors of the Big Bang." Finally, the data confirm a deep connection between quantum mechanics and general relativity."

Studying Gender in Conference Talks: Data From 223rd American Astronomical Society Meeting

"The most significant result from this study is that while the gender ratio of speakers very closely mirrors that of conference attendees, women are under-represented in the question-asker category. We interpret this to be an age-effect, as senior scientists may be more likely to ask questions, and are more commonly men. A strong dependence on the gender of session chairs is found, whereby women ask disproportionately fewer questions in sessions chaired by men. While our results point to laudable progress in gender-balanced speaker selection, we believe future surveys of this kind would help ensure that collaboration at such meetings is as inclusive as possible."

SOFIA ... eine Erfolgsgeschichte ist in Gefahr (in German), January W├Ârners Blog, DLR

[translation] "As part of the current budget statement of NASA it has now let announced from Washington that the continued operation as of 2015 could no longer be financed. That would not only be a major blow for the science that has planned many interesting astronomical research for the coming years, but also for the relationship between NASA and DLR."

Did NASA Ground SOFIA?

Computing a Winner, Fusion a Loser in U.S. Science Budget, Science Insider

"A White House summary of NASA's budget notes that the savings achieved by reducing funding for SOFIA will enable "continued support for higher priority programs, including lower cost, competitive science missions, and extended operations for the Cassini Saturn mission." A more detailed presentation of the space agency's budget proposal, unveiled this afternoon by NASA, says the agency is in talks with its German partner to determine the best path forward for SOFIA."
