PSD Status Report Dr. Lori Glaze, Director of the Planetary Science Division, gave a status report. First addressing the President’s Budget Request (PBR) for Fiscal Year 2021 (FY21) for the Science Mission Directorate (SMD), Dr. Glaze noted that it was one of the strongest science budgets in NASA history, representing a 12% increase over the enacted FY20 budget. The total PBR keeps NASA on track to land on the Moon by 2024; and to help prepare for human exploration at Mars. -
NL#135 May/June
May/June 2007 Issue 135 A Publication for the members of the American Astronomical Society 3 IOP to Publish President’s Column AAS Journals J. Craig Wheeler, [email protected] Whew! A lot has happened! 5 Member Deaths First, my congratulations to John Huchra who was elected to be the next President of the Society. John will formally become President-Elect at the meeting in Hawaii. He will then take over as President at the meeting in St. Louis in June of 2008 and I will serve as Past-President until the 6 Pasadena meeting in June of 2009. We have hired a consultant to lead a one-day Council retreat before the Hawaii meeting to guide the Council toward a more strategic outlook for the Society. Seattle Meeting John has generously agreed to join that effort. I know he will put his energy, intellect, and experience Highlights behind the health and future of the Society. We had a short, intense, and very professional process to issue a Request for Proposals (RFP) to 10 publish the Astrophysical Journal and the Astronomical Journal, to evaluate the proposals, and Award Winners to select a vendor. We are very pleased that the IOP Publishing will be the new publisher of our cherished and prestigious journals and are very optimistic that our new partnership will lead to in Seattle a necessary and valuable evolution of what it means to publish science journals in the globally- connected electronic age. 11 The complex RFP defining our journals and our aspirations for them was put together by a team International consisting of AAS representatives and outside independent consultants. -

The concept is responsive to recommendations of the recent NASA Roadmap to Ocean Worlds study (Hendrix et al., 2019), and to the 2013 Planetary Decadal Survey’s habitability and workings themes (Squyres et al., 2011). The concept was chosen (Ref. 5) from proposals submitted in 2019, under NASA’s Discovery Program, and is currently in its Phase A, competing for selection with three other mission concepts. Voyager 2 showed that Triton has active resurfacing with the potential for erupting plumes and an atmosphere. Coupled with an ionosphere that can create organic snow and the potential for a subsurface ocean, Triton is an exciting exploration target to understand how habitable worlds may develop in our Solar System and beyond. -
Brazilian Government Pressured to Punish Environmental Crimes by Jonathan Watts, the Guardian, Adapted by Newsela Staff on 02.04.19 Word Count 985 Level 1200L
Brazilian government pressured to punish environmental crimes By Jonathan Watts, The Guardian, adapted by Newsela staff on 02.04.19 Word Count 985 Level 1200L Image 1. Mud released by the collapse of a mining company's dam flows in the Paraopeba River near a community of Pataxo Ha-ha-hae indigenous people in Brumadinho, Brazil, Tuesday, January 29, 2019. Photo by: Leo Correa/AP Photo One of the deadliest mining disasters in decades has struck Brazil, and its government has been urged to step up punishments for environmental crimes. A torrent of mud and iron ore bits engulfed the community of Brumadinho on January 25. It continues to take a toll on residents, river systems and freshwater species. At least 99 people died near the site, which is operated by Vale, one of the world's biggest mining companies. Hundreds of people are still missing. Many were eating lunch or resting in a hotel when the tailings dam collapsed and swept them away in a tide of orange sludge. A tailings dam is a collection spot for residue from mining iron ore. It is the second such calamity to strike a Vale facility in the Brazilian state of Minas Gerais in less than four years. In 2015, 19 people were killed when a tailings dam burst at an iron ore mine in the city of Mariana, Brazil. The Mariana dam was co-owned by Vale. This article is available at 5 reading levels at https://newsela.com. The amount of slurry this time is 75 percent lower, at about 3 billion gallons — equal to about 4,500 Olympic-size swimming pools. -
Architecture for Going to the Outer Solar System
ARGOSY ARGOSY: ARchitecture for Going to the Outer solar SYstem Ralph L. McNutt Jr. ll solar system objects are, in principle, targets for human in situ exploration. ARGOSY (ARchitecture for Going to the Outer solar SYstem) addresses anew the problem of human exploration to the outer planets. The ARGOSY architecture approach is scalable in size and power so that increasingly distant destinations—the systems of Jupiter, Saturn, Uranus, and Neptune—can be reached with the same crew size and time require- ments. To enable such missions, achievable technologies with appropriate margins must be used to construct a viable technical approach at the systems level. ARGOSY thus takes the step past Mars in addressing the most difficult part of the Vision for Space AExploration: To extend human presence across the solar system.

The European English Messenger, 23.1 (2014)
The European English Messenger, 23.1 (2014) WILLIAM SHAKESPEARE (1564-1616) Henri VI and the Piccola Familia Isabelle Schwartz-Gastine University of Caen, France In France the main event of this Shakespeare anniversary year is a marathon staging of the three plays of Henry VI by a very young cast, La Piccola Familia, a company created by Thomas Jolly (now aged 32) and some of his friends after they graduated from Rennes Drama School in 2006.1 The project started in 2010 with six or seven actors playing the first two Acts of 1Henry VI, a performance lasting two hours, so already a lengthy enterprise for a short text. Their ultimate aim was to perform the whole of the trilogy in a few years - the idea of adding Richard III was soon abandoned. So they were ready to embark on a completely oversized theatrical “saga”, as they call it2. They won the support of the National Theatre of Cherbourg, in Normandy (Le Trident, www.trident-sn.com), and thus “Cycle 1”, premiered in Cherbourg on January 17th 2012, then toured in Normandy and Brittany, sometimes playing in very small venues, or at best in regional theatres, where they received unanimous acclaim. Due to favourable reviewing in the local and then the national press, and the “likes” of many Facebook Friends (the number growing by the day), the play has now reached the Parisian stage with equally great success. For the time being, “Cycle 1” is staged split into episodes 1 and 2. Each episode is in fact a full play of over three hours with an interval, the average norm in France for a performance.
