Magic Arcs – Sick Science! #203
Check out cool science kits and toys: http://www.stevespanglerscience.com/
It’s probably the world’s most baffling optical illusion. Hold one arc above the other and ask the question, “Which arc is bigger?” The bottom arc will always look bigger than the top one, yet they are actually the same size! Reverse the arcs to make the other one look bigger. What you see is not always what you get! Keep reading and we’ll let you in on some presentation ideas and stunts that will really amaze and fool your friends.

ESA Euronews: Tschuri, die himmlische Badeente
Die Rosetta-Sonde hat ihren Zielkometen Tschuri erreicht. Damit hat für die Wissenschaftler von der ESA, die Rosetta vor zehn Jahren ins All geschickt haben, ein Wettlauf gegen die Zeit begonnen. Denn nun müssen sie den Kometen kartografieren und Daten sammeln, bevor sie im November den Landeroboter aus Rosetta ausklinken und auf Tschuri landen lassen. Dafür muss nun eine geeignete Landestelle gefunden werden – keine leichte Aufgabe. In der aktuellen Ausgabe von euronews Space zeigen uns die Kometen-Jäger in Darmstadt, wie man um einen Kometen fliegt, wie Rosetta ihr Ziel “sieht” und welche Bedeutung das ganze Projekt für die Wissenschaft und das Team hat.

How to orbit a comet
What happens after Rosetta arrives at comet 67P/Churyumov–Gerasimenko? This animation describes the key dates for the next set of manoeuvres that will bring Rosetta even closer to the comet between August and October.
After arriving on 6 August, Rosetta will follow a set of two, three-legged triangular trajectories that require a small thruster burn at each apex. The legs are about 100 km long and it will take Rosetta between three and four days to complete each one.
The first triangle is conducted at a distance of about 100 km from the comet, the second at around 50 km. Then Rosetta will switch to a ‘global mapping phase’ at an altitude of about 30 km. During this period, it will make a ‘night excursion’, whereby the ground track of the spacecraft will be on the night-side of the comet (with the spacecraft still fully illuminated the Sun).
In October Rosetta will transfer to a close mapping phase to observe the comet from a distance of 10 km. The spacecraft will move even closer to dispatch lander Philae to the surface in November.
In this animation the comet is an artist’s impression and is not to scale with the spacecraft. The comet rotation is not representative (67P rotates once per 12.4 hours). Dates may be subject to change.

Philae’s mission at comet 67P
Extended version of Philae touchdown animation to include visualisations of some of the science experiments on the lander.
The animation begins with the deployment of Philae from Rosetta at comet 67P/Churyumov–Gerasimenko in November 2014. Rosetta will come to within about 10 km of the nucleus to deploy Philae, which will take several hours to reach the surface. Because of the comet’s extremely low gravity, landing gear will absorb the small forces of landing while ice screws in the probe’s feet and a harpoon system will lock the probe to the surface. At the same time a thruster on top of the lander will push it down to counteract the impulse of the harpoon imparted in the opposite direction. Once it is anchored to the comet, the lander will begin its primary science mission, based on its 64-hour initial battery lifetime. The animation then shows five of Philae’s 10 instruments in action: CIVA, ROLIS, SD2, MUPUS and APXS.
Rosetta’s Philae lander is provided by a consortium led by DLR, MPS, CNES and ASI.

NASA Renames Historic Facility in Honor of Neil Armstrong
During a ceremony at Kennedy Space Center on Monday, July 21, NASA renamed the center’s Operations and Checkout Building in honor of late astronaut Neil Armstrong, who passed away in 2012. The ceremony included NASA Administrator Charles Bolden, Kennedy Center Director Robert Cabana, Apollo 11’s Michael Collins and Buzz Aldrin and astronaut Jim Lovell, who was the mission’s back-up commander. International Space Station NASA astronauts Steve Swanson, who is the current station commander, and Reid Wiseman, also took part in the ceremony via satellite downlink from their orbiting laboratory 260 miles above Earth.
Kennedy’s Operations and Checkout Building has played a vital role in NASA’s spaceflight history. It was used during the Apollo program to process and test the command, service and lunar modules. Today, the facility is being used to process and assemble NASA’s Orion spacecraft, which the agency will use to send astronauts to an asteroid in the 2020s and Mars in the 2030s.
