Sometimes we all need a getaway, if only for 8 minutes and 58 seconds...

European Space Agency (ESA - Arianespace) launched its Rosetta Mission on 3/2/2004 and reached Comet 67P Churyumov-Gerasmenko on 8/2014. The lander, Philae, successfully landed on the comet's surface (11/12/2014) as Rosetta remains in orbit. Please enjoy the photos of the comet sent back by Rosetta!

Partnerships
The orbiter's scientific payload is provided by scientific consortia from institutes across Europe and the United States.
The lander is provided by a European consortium headed by the German Aerospace Research Institute (DLR). Other members of the consortium are ESA, CNES and institutes from Austria, Finland, France, Hungary, Ireland, Italy, and the United Kingdom.

They should have used Duracell! What a shame the batteries died : (

I watched an excellent documentary on science channel 193,
Landing On A Comet: Rosetta Mission. What an incredible feat to be landing on comet 67P and bringing able to view groundbreaking images and technology.

G'evening everyone,

Is anyone interested in Science "Jeopardy?"
These are the answers:

Enjoy!
Swan

1. It takes about once every 200 million years to accomplish.

2. It spins at roughly 800,000 km/hr or about 500,000 MPH.

3. There are 1760 of them.

4. It travels at 1 mile per 5 seconds.

5. To accomplish this feat, it takes 371 miles per second (MPS)

Okay, here goes:

1. The planets in our solar system orbit (revolve) around the sun, and the sun orbits (revolves) around the center of the Milky Way galaxy. We take about 200 million years to revolve once around the galaxy’s center. This length of time is called a “cosmic year.”

4. The sound of the thunder travels at a speed of about 1100 feet per second or about 1 mile in 5 seconds.

2. The usual star’s 500,000-mph (800,000km) pace through space.

Fantastic! Yes, it is also referred to as a Galactic Year.

4. The sound of the thunder travels at a speed of about 1100 feet per second or about 1 mile in 5 seconds. Yes.

2. The usual star’s 500,000-mph (800,000km) pace through space. The Milky Way Galaxy spins at about 515,000 mph. Since stars are within the galaxy, your answer is also true. Bravo!

???

Two answers remain:
3. There are 1760 of them.
5. To accomplish this feat, it takes 371 miles per second (MPS)

3. There are there 1760 yards in a mile. Yes there are!

5. The speed of sound? Non; not the speed of sound. Good try!

One answer left:

5. To accomplish this feat, it takes 371 miles per second (MPS) This is a huge number and is equivalent to 1,332,000mph.

The only thing I could find related to that number was that the entire group of galaxies, including the Milk Way, is traveling at 1,332,000 MPH towards the Virgo Super Cluster of galaxies.

1. It takes about once every 200 million years to accomplish. A Galactic Year: The amount of time it takes the Sun to travel once around the galaxy.

2. It spins at roughly 800,000 km/hr or about 500,000 MPH. The Milky Way Galaxy.

3. There are 1760 of them. Yards in a mile.

4. It travels at 1 mile per 5 seconds. Sound.

5. To accomplish this feat, it takes 371 miles per second. The 'escape velocity' of the Sun. Our rockets must attain a speed of 25,000mph to escape our gravitational force on Earth; and a rocket on the Sun would have to attain a speed of 1,332,000 mph to escape the Sun's gravity. Amazing, isn't it?

Aussie: Because science is broad and covers numerous categories, I certainly would not want to limit any area(s) of study from the thread; and, of course, Geology, Computer Science, and Physics are very important here.

As I posted these questions, however, I wasn't thinking about Play Station3's and the AFRL, nor the partial creation/ destruction of Earths surface, nor 9mm grain loaded etc. etc. As you can see, these seemingly could be extremely difficult to find and might garner a limited interest??? My questions (or Answers) are more grounded.

Perhaps I will give the category under which the Questions/ Answers are given so as to prevent any confusion from here onward. Many thanks.
Swan

G'evening everyone:

Interested in another round of Science Jeopardy? (SPACE)

1. It's influence is thought to extend outward beyond the solar system to approximately 3.5 light years (30 trillion km.)

2. It's outer limit defines the cosmographical boundary of the solar system.

3. They are Brahms, Beethoven, Chopin among others.

4. By definition, it lasts one(1) billionth of a second.

5. They are the three (3) densest planets in the solar system.

1. The sun - Yes. The sun's gravitational influence extends approximately 3 1/2 light years from our solar system to the Oort Cloud.

2. Oort Cloud - Yes.

3. Composers - Yes, Chopin, Brahms, and Beethoven are, indeed, composers; how are they related to space?

4. Nanosecond - Yes. A nanosecond is a billionth of a second.

5. Earth, Mercury, and Mars - Yes. These three planets are the densest of the 9 in our solar system. (I still include Pluto in our family of planets.)

Congratulations. Well done!
Question #3 remains: They are Brahms, Beethoven, and Chopin among others...
