Hey, all -


First: exciting things happened this week! Ms. Kjonaas generously helped to compile a lot of the cool information that you can find below.


Second: if you're bored this Saturday, and want to not be bored, we're planning on going to see Interstellar at Providence Place at 4:15pm! (Standard, not IMAX.) If you're interested, please let me know!


Have a great end of the week -


Brian

Rosetta

Wednesday, Nov. 12


Rosetta, the first mission to orbit a comet, successfully landed its probe, Philae, on Comet 67P on Wednesday. Landing a probe on a comet is an incredibly challenging task - you can read more about the landing here.


It has recently come to light that the landing was not quite smooth - Philae bounced twice and ultimately landed on its side in the shadow of a cliff. Its solar panels will not be able to collect enough energy to keep it powered past the life of the battery, making the mission a race against time. The European Space Agency is looking into how they might repurpose the drill or harpoon located on the lander to give it a jolt.


The descent took seven hours, after a long ten years of travelling through space to rendezvous with the comet. Rosetta was launched in March of 2004 and traveled a total of 6.4 billion kilometers.


Above: the first photo of Philae on Comet 67P. It’s a composite photo, taken by a camera on the orbiter.

Below: a video (released before the landing) of the process by which the Philae lander descended.

Protoplanetary Disk Image

For the first time we have an image of a protoplanetary disk -- hot gas and dust swirling together to form a star and its orbiting planets. The young star in the center of this disk has already ignited, and planets are starting to form. It’s a beautiful image, but it’s also very important scientifically to finally observe the formation of a solar system. This is also what our solar system looked like almost five billion years ago!
