The Astro2010 Decadal Survey recommended a Wide Field Infrared Survey Telescope (WFIRST) as its top priority for a new large space mission. The report of the WFIRST-AFTA Science Definition Team (SDT) presents a Design Reference Mission for WFIRST that employs one of the 2.4-m, Hubble-quality mirror assemblies recently made available to NASA. The 2.4-m primary mirror enables a mission with greater sensitivity and higher angular resolution than the smaller aperture designs previously considered for WFIRST, increasing both the science return of the primary surveys and the capabilities of WFIRST as a Guest Observer facility. The option of adding an on-axis, coronagraphic instrument would enable imaging and spectroscopic studies of planets around nearby stars. This short article, produced as a companion to the SDT report, summarises the key points of the WFIRST-2.4 DRM. It highlights the remarkable opportunity that the 2.4-m telescope affords for advances in many fields of astrophysics and cosmology, including dark energy, the demographics and characterisation of exoplanets, the evolution of galaxies and quasars, and the stellar populations of the Milky Way and its neighbours.
NASA should bring Mars rocks back to Earth, says panel
Bringing Mars rocks to Earth should be a top priority for NASA in the coming decade, says a high-level panel of planetary scientists. It also recommended a mission to Jupiter's icy moon, Europa, thought to harbour an ocean of liquid water beneath its surface. But if the agency cannot afford such multi-billion-dollar "flagship" missions, they should be delayed in favour of smaller missions, the panel says. The panel's recommendations are not binding, but the report is likely to strongly influence NASA's decisions. Read more
The NRC is asked once each decade to prioritise NASA goals. The results of this survey have just been released!
The National Research Council (NRC) conducts studies that provide a science community consensus on key questions posed by NASA and other U.S. Government agencies. The broadest of these studies in NASAs areas of research are decadal surveys. As the name implies, NASA and its partners ask the NRC once each decade to look out ten or more years into the future and prioritise research areas, observations, and notional missions to make those observations.

The AAS Council adopted a Resolution on the 2010 Decadal Survey Report on August 13, 2010:
"The American Astronomical Society enthusiastically endorses the Astro2010 Decadal Survey: New Worlds, New Horizons in Astronomy and Astrophysics. Given recent advances in technology and understanding, this is a time of extraordinary opportunity for research in astronomy and astrophysics. This report is based on a comprehensive community-driven process, and presents exciting yet realistic recommendations for the next decade. The AAS urges the astronomical community to support the report and its priorities."
Goddard staff watched the future of astronomy and astrophysics mapped out Friday Aug. 13 during the nationwide web-cast of the 2010 decadal survey organised by the National Research Council. About 100 Goddard scientists, engineers and other employees watched, some participating online through Twitter on Blackberries and laptops. They joined thousands in more than 80 telecast centres around the country, including six NASA facilities and dozens of universities. Read more
The next astronomy decadal survey has formally begun, and the Astro2010 Decadal Survey committee has been tasked to " survey the field of space- and ground-based astronomy and astrophysics, recommending priorities for the most important scientific and technical activities of the decade 2010-2020."

The Astro2010 report, New Worlds, New Horizons in Astronomy and Astrophysics, will be publically released in pre-publication form via the National Academies Press web site at 11:00am EDT on August 13, 2010 (the fully edited final publication version of the report will emerge later in the year).
For the public release on August 13, 2010 we are coordinating an eTownHall meeting to take place from 11:00am to 12:30pm EDT. What does this eTownHall entail? A public briefing/release event will be webcast live from the Keck Centre of the National Academies in DC, including discussions on the report and its recommended program from the chair and several committee members and a short question and answer session.
