Groundbreaking analysis of a distant, fast-moving comet has revealed new details in how asteroids form, shedding light on the formation of unusual shapes and, potentially, paving the way for more effective protection of the Earth from meteor impacts.The asteroid, Comet 67P/Churyumov–Gerasimenko, is around 2.7 miles across and moving at as much as 84,000 miles per hour, but scientists have long been fascinated by its unusual shape.The vaguely dumbbell-like form, with two distinct lobes joined by a central portion, helped make 67P/C-G the target of the European Space Agency’s Rosetta mission.That dropped the Philae lander onto the asteroid in November 2014, where – despite a botched touchdown that saw experimentation end prematurely – it sent back valuable details about the chemical makeup.Now, using data from Rosetta’s OSIRIS camera – the Optical, Spectroscopic, and Infrared Remote Imaging System that tracks visible, near infrared, and near ultraviolet wavelengths – the ESA has pieced together a map of the faults and fractures that riddle the comet.Using stress modeling and 3D analysis, insight into how various forces shaped the rock and ice has been unlocked.
Strap in and fire up your warp drives because this week we are traversing deep space and then some.First we’re going to hang around some dead stars, but really it’s cooler than you think.When stars die they tend to leave behind evidence of their existence.Often that evidence comes in the form of gorgeous tendrils of gas and clouds that can emit different wavelengths of light, making for some very pretty photos.Next we’ll quickly swing by the comet 67p to check out its icy and rocky terrain.To this day the Rosetta mission stills holds the record for the first to land a spacecraft on a comet (RIP Philae) and return photos from it.
The Rosetta mission’s Philae lander descended toward the two-and-a-half-mile-wide comet at a human’s walking pace.There are tantalising reasons to land on smaller space rocks, like comets and asteroids, rather than large planets or moons.Asteroid mining company Planetary Resources estimates that the 16,000 rocks near Earth could hold two trillion metric tonnes of water.A widely cited Goldman Sachs report says that an American football field-sized asteroid could contain “$25 billion [£19 billion] to $50 billion [£38 billion] worth of platinum.”The resources in these rocks could be crucial to developing space-based infrastructure for future deep-space travel that doesn’t require bringing everything you need from Earth.Back in 2005, Japanese spacecraft Hayabusa damaged itself in a crash against the asteroid Itokawa while trying to collect a sample, before a successful return in 2010.
The European Space Agency’s Rosetta mission to the comet 67P/Churyumov-Gerasimenko was one for the ages, providing an unprecedented look at this oddly shaped celestial object.The Rosetta probe captured nearly 100,000 images over the course of its mission, all of which are now freely available to the public in a single Rosetta archive.The Rosetta Image Archive is now complete, as the last set of images, taken by the Rosetta probe from late July 2016 to the end of the mission on 30 September 2016, have been processed and uploaded to the Archive Image Browser and the Planetary Science Archive.The ESA also released a stunning new video (below) made from Rosetta’s final set of photos.The shots were taken during the last hours of the probe’s life, as it descended towards an ancient pit.Over the course of its 12-year mission, the Rosetta probe captured thousands of hi-res images with its OSIRIS camera.
Researchers have come up with a new theory about the dwarf planet's origins after taking a close look at Sputnik Planitia, the vast nitrogen-ice glacier that constitutes the left lobe of Pluto's famous "heart" feature."We found an intriguing consistency between the estimated amount of nitrogen inside the glacier and the amount that would be expected if Pluto was formed by the agglomeration of roughly a billion comets or other Kuiper Belt objects similar in chemical composition to 67P, the comet explored by Rosetta," Chris Glein, a scientist at the Southwest Research Institute (SwRI) in San Antonio, said in a statement.[Photos of Pluto and Its Moons]The European Space Agency's Rosetta mission orbited Comet 67P/Churyumov-Gerasimenko from 2014 through 2016.The orbiting mothership also dropped a lander named Philae onto the icy body, pulling off the first-ever soft touchdown on a comet's surface.(The Kuiper Belt is the ring of frigid objects beyond Neptune's orbit; Pluto is the belt's largest resident.)
The European Space Agency's Rosetta spacecraft arrived at Comet 67P/Churyumov–Gerasimenko in 2014 and subsequently became the first mission to ever orbit around a comet.Additionally, its small Philae lander became the first to touch down on a comet’s surface—although it was subsequently lost after it was unable to deploy its solar panels in a proper configuration to capture enough energy to continue operations.During its two years in varying orbits around the comet, which is about 4km on its longest side, Rosetta captured some unprecedented imagery of these Solar System interlopers.Now, a Twitter user named landru79 has combed through the Rosetta image archives and found a striking series of 12.5-second exposure photos taken from about 13km away from the comet.The images from June 1, 2016, are combined into the short video below.The bright dots travelling from the top of the frame to the bottom, which look something like snow, are in fact background stars.
Can we, can we hitch a ride?NASA is drawing up plans to send a robot out into space to either drill into the comet 67P/Churyumov-Gerasimenko – or checking out Titan, Saturn’s largest moon.The two proposed missions are still in their very early design phases, and were chosen from 12 ideas submitted in April to the American space agency’s New Frontiers program, a longstanding investigation into the bodies that make up the Solar System.The Comet Astrobiology Exploration Sample Return (CAESAR) involves Earth's boffins revisiting comet 67P.In 2014, the European Space Agency successfully put its Rosetta spacecraft in orbit around the rubber-ducky-shaped comet.The probe had a lander module named Philae that touchdown on the cosmic rock hundreds of metres from its target landing area in a spot of shade, where it was unable to power itself with sunlight.

With the historic Rosetta mission now over, the European Space Agency has compiled a four-minute simulation showing the spacecraft s complete journey as it weaved around Comet 67P/Churyumov–Gerasimenko.Things get started on July 31st, 2014 as Rosetta began to wind down its 10-year journey to the comet.The probe came to within 60 miles 100 km on August 6th, and from there, it gradually approached the oddly-shaped comet.Its initial flybys provided the first close-up images of the comet, while allowing mission planners to choose a landing site for the soon-to-be ill-fated Philae lander.Key stages in the mission include Rosetta s maneuvers as it prepared to dispatch Philae to the comet s surface, close flybys in February and March of 2015, and course corrections performed to protect the probe from the comet s increased activity in August 2015.In the spring of 2016, Rosetta went on another far excursion, followed by a close flyby when its instruments made several critical observations.
The European Space Agency has had a rough ride this year, first with Rosetta and Philae and more recently, stacking into Mars with the Schiaparelli lander.The crash site was previously captured in black and white by NASA's Mars Orbiter and now it's had a second crack, though this time in colour.While the colour images don't reveal anything particularly groundbreaking, the distinctive scorch mark all but confirms Schiaparelli's fate, if for some reason you were holding out on the alien abduction theory.What is a little more interesting is this second image below, also snapped by the MRO on November 1st.This picture shows the lander's rear heatshield and parachute on two different days.Why does the top white shape look different?
Unless Matt Damon becomes stranded on Comet 67P/Churyumov–Gerasimenko any time soon and needs an emergency means of calling back to Earth, the world will never hear from the Rosetta spacecraft again.But the European vehicle served humanity well since its launch 12 years ago.Rosetta became the first probe to both orbit a comet and deploy a lander to a comet's surface.On Friday morning, the spacecraft joined its small lander, Philae, on the surface of its comet.Even before the European Space Agency s Giotto spacecraft came within 600km of the nucleus of Halley s Comet in 1986, the agency was already thinking about a comet lander as a follow-up mission.After finally launching in 2004, Rosetta took a long time to reach Comet 67P/Churyumov–Gerasimenko.
When Halley s Comet paid us a visit back in 1986, the European Space Agency s Giotto spacecraft was sent to explore the incoming ball of ice and dirt.The first images beamed back by Rosetta revealed a very rubber-ducky like object.Launched on March 2, 2004, the Rosetta probe began to make its way towards the comet, passing by Mars and several large asteroids along the way.Follow-up studies showed that the comet merged from two separate objects.Instead of securing itself to the surface with its harpoon-fired grappling hooks, Philae bounced several times, and eventually settled within a shadowed crevice.It awoke briefly a few months later, but was eventually declared dead.
Let s all take a moment and pour one out metaphorically for Rosetta, the pioneering spacecraft that gave our newly spacefaring race its first comet landing.The orbiter performed its final task early this morning, making a controlled crash into the comet s surface, destroying itself in the process but gathering valuable data down to the last minute.This was a risky, fascinating, and very successful mission, despite the hard landing and subsequent loss of the Philae lander.Making a rendezvous with a comet is as difficult as it is awesome, and today is the end of 12 years of hard work by the team at the European Space Agency.Many missions end the doom of their own hardware, and Rosetta was planned no differently from dozens of other probes and orbiters.In this case, Rosetta s final job was to sample gases and dust from the comet s scanty atmosphere, and snap high-resolution images from just hundreds of feet above its surface.
