If the landing is successful, it will be the first time scientists have landed a probe
on a comet, and it will be the completion of a mission that began 10 years ago when the Rosetta spacecraft launched.
The Physics World «2014 Breakthrough of the Year» went to the European Space Agency's Rosetta mission1 for being the first to land a spacecraft (Philae)
on a comet (67P / Churyumov - Gerasimenko), on 12 November.
Unicorns can run
on comet tails and jump from one solar system to the next which is why we never see one...

on a comet.
We have landed successfully
on a comet, but I still can't use my apple products successfully on Just Arsenal is anyone else having problems from time to time?????? OH yar on the subject of football Podolski should stay
We've put robots on both the moon and mars, but scientists have never tried to soft - land a robot
on a comet — until now.
Such biomolecules or their precursors could have ridden to Earth
on comets or asteroids to seed life on our planet — and possibly elsewhere.
They've found that the ice
on comets has deuterium concentrations very similar to the water in our oceans.
Philae has been found, nestled in a shadowy crevice
on comet 67P / Churyumov - Gerasimenko.
The comet lander, lost since its tumultuous touch down
on the comet on November 12, 2014, turned up in images taken by the Rosetta orbiter on September 2.
On 30 September, the European Space Agency probe landed
on comet 67P / Churyumov - Gerasimenko, in a spectacular finish to its two years spent in orbit around the space rock.
In November that year, Rosetta's companion lander, Philae, made a bumpy touchdown and survived for a few days
on the comet before being lost — though Rosetta did eventually find it again.
The comet lander, lost since its tumultuous touchdown
on the comet on November 12, 2014, turned up in images taken by the Rosetta orbiter on September 2.
Finally, in 2014, Rosetta, a European mission, will attempt a landing
on the comet Churyumov - Gerasimenko.
Nodules seen in fresh pit walls and cliff faces
on comet 67P / Churyumov - Gerasimenko could be the fundamental units of comet formation.
But disintegration would in some ways be even more revealing because it would provide data
on the comet's internal construction — and, by extension, on the way it formed in the first place.
Scientists using the Rosetta spacecraft — which arrived at 67P in August and became the first mission to orbit and land
on a comet — now think they may have discovered the source of these patterns on cliff faces and in deep pits: layer upon layer of rounded nodules, 1 to 3 meters across.
One spacecraft, called Deep Impact, will attempt to blast a huge hole in a comet; another is intended to land
on a comet and scoop up parts of its surface.
«It's been looked for [
on comets] spectroscopically with telescopes but the content seems so low you can't see it that way.»
It should be more variable if this chemical reaction were generating oxygen
on the comet, she says.
Instead, it may be generated by interactions of water, the solar wind and sand
on the comet's surface.
Alice also documented a surprising lack of exposed water ice
on the comet's surface and identified an extremely volatile, unexpected gas in the comet's atmosphere — molecular oxygen.
The next steps for studying the concept would be to do more high - fidelity simulations and try casting a mini-harpoon at a target that mimics the material found
on a comet or asteroid.
This is why the new generation of comets still has a low density and is rich in volatile substances — properties which have also been found
on the comet Chury.
A concept called Comet Hitchhiker, developed at NASA's Jet Propulsion Laboratory, Pasadena, California, puts forth a new way to get into orbit and land
on comets and asteroids, using the kinetic energy — the energy of motion — of these small bodies.
For any spacecraft landing
on a comet or asteroid, being able to slow down enough to arrive safely is critical.
This is the last photo we're getting from Philae before it lands
on the comet on 12 November.
They still don't know exactly where the probe is
on the comet's surface, but Holger Sierks, who is in charge of the OSIRIS camera on Rosetta, said they should have a picture of Philae's 1 kilometre - high bounce after landing, which will help pinpoint its final resting spot.
Other big news included the rise and fall of a claimed detection of gravitational waves, new findings about the history of early humans from analyses of DNA and the spectacular landing of the Rosetta spacecraft's robotic explorer Philae
on comet 67P / Churyumov — Gerasimenko.
Despite seven months adrift and alone
on comet 67P / Churyumov - Gerasimenko since its bumpy landing last year, Philae is back and ready for science.
In November that year, Rosetta's companion lander Philae thrilled us with a bumpy touchdown, surviving just a few days
on the comet before being lost — though Rosetta did eventually find it again.
The European Space Agency's probe, which made its historic landing
on the comet on Wednesday, 12 November, has not moved from its landing spot and so its solar panels are not getting enough sunlight.
Planetary scientist H. Jay Melosh is of course correct that the Deep Impact probe will have a negligibly small effect
on comet Tempel I's orbit [«Impact Geologist Waits for the Big One to Hit,» Discover Dialogue, July].
PHILAE FOUND The landing spot of the Philae comet lander (left, and bottom right), seen in this September 2 image from the Rosetta spacecraft, has been hiding
on comet 67P (top right) since November 2014.
Since January, temperatures
on the comet have been too chilly for Philae's electronics; mission scientists stopped listening for radio signals from the lander in July.
The long exposure means we can see details
on the comet's surface, along with jets of gas emerging as it heats up on its journey towards the sun.
Three boulders (shown) balance precariously
on comet 67P / Churyumov - Gerasimenko in this Sept. 16 image taken 29 kilometers above the surface by the Rosetta spacecraft
Balancing boulders on Earth are either deposited by glaciers or carved by wind and water erosion — none of which exist
on a comet.
The discovery comes about one month before the end of the Rosetta mission; the orbiter is scheduled to land
on the comet on September 30 and then shut down.
It has been seven months since the little lander touched down
on the comet.
As of press time, Rosetta is scheduled to drop a lander, named Philae, in mid-November onto a site
on the comet's surface named Agilkia — another space exploration first.
The existence of the craters, as well as the discovery of steep cliffs and pinnacles
on the comet's landscape, imply that Wild 2 is a cohesive structure as opposed to a loosely connected rubble pile.
The Rosetta spacecraft's final resting place could be
on the comet it called home for over two years.
It will be the first time that landing
on a comet has ever been attempted.
But he is pleased to see that such molecules can indeed form
on comets.
DARMSTADT, GERMANY — The Rosetta orbiter on Wednesday dropped a spidery, three - legged robot the size of a small refrigerator and watched as it tentatively set down
on a comet — the first time that the surface of these primordial balls of dust and ice has ever been explored.
Philae has landed
on a comet.
The European Space Agency's Rosetta spacecraft has spotted an amino acid
on the comet it orbits — confirming that a ball of ice and dust can hold a major building block of life.
The addition of glycine and phosphorus means that all the major types of prebiotics have been discovered
on the comet (Science Advances, doi.org/bjfn).
With the addition of glycine and phosphorous, all the major types of prebiotics have been found
on the comet.
