This is partly because of expense: a one= -way robot mission is far less complicated than a two-way one, and there ar= e all kinds of unknown variables that come into play in sample return missi= ons. Now, as a Japanese space probe approaches the Ryugu asteroid, there's = a chance that number will go up to four.After a long 186.4 million-mile jou= rney =E2=80=94 one which took about three and half years =E2=80=94 a spacec= raft named Hayabusa-2 has successfully rendezvoused=C2=A0with a unique aste= roid named Ryugu.=E2=80=9CFrom this point, we are planning to conduct explo= ratory activities in the vicinity of the asteroid, including scientific obs= ervation of asteroid Ryugu and surveying the asteroid for sample collection= ,=E2=80=9D Japan Aerospace Exploration Agency JAXA confirmed in a press rel= ease on Wednesday.Following its arrival, the next step is to prepare to sur= vey the asteroid for sample collections. Hayabusa-2 is expected to bring ro= cks and dust to Earth from the carbonaceous asteroid.This alone is an excit= ing=C2=A0prospect to many in the asteroid-studying community. =20 -=20 - =20 =E2=80=9COne of the great aspects of Hayabusa-2 is that it will be a sample= -return, so it has to interact with the surface of that object,=E2=80=9D Al= an Fitzsimmons, an astronomer in the QUB Astrophysics Research Centre, expl= ained in a press conference hosted by the B612 Foundation on Thursday. =E2= =80=9CIn the past we have only done that with a different type of asteroid.= =E2=80=9DThose past missions include NASA=E2=80=99s NEAR Shoemaker, which c= ollected samples from an asteroid named Eros in 2001. (Unlike Hayabusa-2, N= EAR Shoemaker was not a sample return mission, however.)=C2=A0Remote studie= s of those=C2=A0samples,=C2=A0according to NASA, have since provided scient= ists with a better understanding of how asteroids like Eros are linked to m= eteorite samples found on Earth.Eros=C2=A0is an S-type asteroid =E2=80=94 s= hort for silicaceous asteroid =E2=80=94 which means it orbits the sun, and = is mostly composed of nickel-iron rock. Ryugu is thought to be different, a= C-type=C2=A0or=C2=A0carbonaceous asteroid=E2=80=94 in other words, contain= ing largely carbon. While most asteroids, according to Fitzsimmons, are bel= ieved to be C-type, it is important for scientists to continue to learn abo= ut all different types of asteroids.=E2=80=9CBut that doesn=E2=80=99t guara= ntee that when we want to deflect or closely inspect an asteroid in the fut= ure that it will be silicate, it could well be a carbonaceous asteroid... a= nd so we are going to learn a lot, first of all, just from the interaction,= =E2=80=9D he said, referring to the interaction between Hayabusa-2 and Ryug= u.The advancements made in such little time during this mission are remarka= ble. As JAXA explains on its information page, not too long ago Ryugu was= =C2=A0merely a featureless=C2=A0dot on the spacecraft's Star Tracker. It wa= s not until earlier this week that scientists got a close look at the aster= oid, and were surprised by its shape.=E2=80=9CFrom a distance, Ryugu initia= lly appeared round, then gradually turned into a square before becoming a b= eautiful shape similar to fluorite, known as the 'firefly stone' in Japanes= e,=E2=80=9D project manager Yuichi Tsuda said in a 25 June statement."This = form of Ryugu is scientifically surprising, and also poses a few engineerin= g challenges,"=C2=A0the statement added, referring=C2=A0specifically to the= challenge of landing on a low-mass and therefore low-gravity object like R= yugu.Fitzsimmons noted that the spacecraft's arrival at Ryugu has already y= ielded important scientific data.=E2=80=9CWe are seeing on its surface a fa= irly complex terrain,=E2=80=9D he told Salon. =E2=80=9CIt is something we d= id somewhat anticipate given that many of these objects of this size are ru= bble-pile asteroids... they are not a single cohesive body that you might e= xpect to see if you are a fan of 'Star Wars' or science fiction movies.=E2= =80=9D Still,=C2=A0it will be some time before the samples=C2=A0arrive in an Earth= lab. In late 2019,=C2=A0 Hayabusa-2 will start its one-year journey back t= o Earth =E2=80=94 universe-willing=C2=A0=E2=80=94 with its precious=C2=A0ro= ck samples in hand. ------=_Part_40708_310056935.1530229258113 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <html><head></head><body><div style=3D"color:#000; background-color:#fff; f= ont-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font= -size:13px"><section style=3D"box-sizing: border-box; -webkit-font-smoothin= g: antialiased; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; fo= nt-size: 16px;" id=3D"yui_3_16_0_1_1530142089458_136384"><h1 style=3D"box-s= izing: border-box; -webkit-font-smoothing: antialiased; margin-top: 1em; ma= rgin-bottom: 0.5rem; font-family: "Domaine Display Extra Bold", s= ans-serif; font-weight: 500; line-height: 1.2; color: inherit;" id=3D"yui_3= _16_0_1_1530142089458_136385">Japanese spacecraft arrives at Ryugu asteroid= , ready to bring samples back to Earth</h1><h2 style=3D"box-sizing: border-= box; -webkit-font-smoothing: antialiased; margin-top: 0px; margin-bottom: 1= em; font-family: inherit; font-weight: 300; line-height: 1.42; color: inher= it; font-size: 1.1em;" id=3D"yui_3_16_0_1_1530142089458_136386">Hayabusa-2 = arrived intact at the asteroid Ryugu following a 3.5 year journey</h2></sec= tion><div id=3D"yui_3_16_0_1_1530142089458_136387"><br></div><div data-url= =3D"https://www.salon.com/2018/06/28/japanese-spacecraft-arrives-at-ryugu-a= steroid-ready-to-bring-samples-back-to-earth/" data-title=3D"Japanese space= craft arrives at Ryugu asteroid, ready to bring samples back to Earth" data= -description=3D"Hayabusa-2 arrived intact at the asteroid Ryugu following a= 3.5 year journey" style=3D"box-sizing: border-box; -webkit-font-smoothing:= antialiased; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font= -size: 16px; clear: both;" id=3D"yui_3_16_0_1_1530142089458_136389"><div ar= ia-labelledby=3D"at-fe2df509-8126-4d20-b6c1-90a22342264c" role=3D"region" s= tyle=3D"box-sizing: border-box; -webkit-font-smoothing: antialiased; positi= on: relative; margin: 0px; color: rgb(255, 255, 255); font-size: 0px; font-= family: "helvetica neue", helvetica, arial, sans-serif; padding: = 0px; line-height: 0; animation-fill-mode: both; animation-timing-function: = ease-out; animation-duration: 0.3s; opacity: 1 !important;" id=3D"yui_3_16_= 0_1_1530142089458_136390"></div></div><section style=3D"box-sizing: border-= box; -webkit-font-smoothing: antialiased; margin-bottom: 2em; padding: 0px = 11px 0px 0px; color: rgb(33, 37, 41); font-family: Roboto, sans-serif; font= -size: 16px;" id=3D"yui_3_16_0_1_1530142089458_136438"><h5 style=3D"box-siz= ing: border-box; -webkit-font-smoothing: antialiased; margin-top: 1em; marg= in-bottom: 0.5rem; font-family: inherit; line-height: 1.2; color: rgb(238, = 44, 29); font-size: 0.75em; text-transform: uppercase;" id=3D"yui_3_16_0_1_= 1530142089458_136439"><a href=3D"https://www.salon.com/writer/nicole-karlis= " style=3D"box-sizing: border-box; -webkit-font-smoothing: antialiased; col= or: rgb(238, 44, 29); text-decoration-line: none;" id=3D"yui_3_16_0_1_15301= 42089458_136440">NICOLE KARLIS</a></h5><h6 style=3D"box-sizing: border-box;= -webkit-font-smoothing: antialiased; margin-top: 0px; margin-bottom: 0.5re= m; font-family: inherit; line-height: 1.2; color: rgb(167, 169, 171); font-= size: 0.7em; text-transform: uppercase;" id=3D"yui_3_16_0_1_1530142089458_1= 36441">JUNE 28, 2018 10:00PM (UTC)</h6></section><article style=3D"box-sizi= ng: border-box; -webkit-font-smoothing: antialiased; color: rgb(33, 37, 41)= ; font-family: Roboto, sans-serif; font-size: 16px;" id=3D"yui_3_16_0_1_153= 0142089458_136442"><div style=3D"box-sizing: border-box; -webkit-font-smoot= hing: antialiased; margin-top: 20px; margin-bottom: 20px; line-height: 1.9e= m;" id=3D"yui_3_16_0_1_1530142089458_136443">Humanity has dispatched h= umans and/or robots to explore many different alien worlds in our solar sys= tem, yet the number of large bodies from which we have brought samples back= to Earth numbers only three: the Moon, Comet 81/P, and asteroid 25143 Itok= awa.
