Oh uzh eti kosmicheskie luchi sverhvysokih energii! Vse hotyat ih registrirovat'. Pri etom metodiki mogut byt' raznymi. Naprimer, mozhno pytat'sya nablyudat' radioizluchenie.
Ideya v izluchenii, sozdavaemom elektron-pozitronnymi parami, dvizhushimisya v zemnom magnitnom pole.
Dlya takih nablyudenii nuzhny novye instrumenty. Takim budet teleskop LOFAR (Low-Frequency Array), rabotayushii na 10-200 MHz. Uzhe sushestvuet prototip: LOPES. V otdalennom budushem poyavit'sya kilometrovaya reshetka (Square-Kilometer-Array SKA). Eto eshe bolee moshnyi instrument. LOFAR budet videt' livni ot kosmicheskih luchei s energiei ot 2*10^14 eV do ~10^20 eV.

Opisyvaetsya budushii rentgenovskii sputnik XEUS. Osnovnye zadachi apparata: izuchenie prevyh sverhmassivnyh chernyh dyr, izuchenie obrazovaniya gravitacionno svyazannyh sistem iz temnogo veshestva, issledovanie evolyucii obrazovaniya tyazhelyh elementov, izuchenie mezhgaoakticheskogo veshestva.
Rentgenovskii teleskop budet imet' ochen' bol'shuyu sobirayushuyu ploshad',
a takzhe otlichnoe spektral'noe i uglovoe razreshenie. Poslednee budet
dostignuto za schet gigantskogo fokusnogo rasstoyaniya: 50 metrov!
Dlya etogo sputnik budet sdelan iz dvuh nesvyazannyh mezhdu soboi chastei.

V ideale vse teleskopy hotelos' by zapustit' v kosmos, no eto dorogo, naprimer, Habbl stoit dorozhe vseh zemnyh vmeste vzyatyh (hotya "v kosmose dollar vesit men'she", B.Pachinskii (c)). Odnako dlya IK nablyudenii dostatochno postavit' teleskop na samolet. Samoletnye observatorii ispol'zuyutsya uzhe davno (naprimer, kol'ca Urana, otkrytye vo vremya pokrytiya Uranom slaboi zvezdochki, nablyudalis' imenno na takoi observatoii).

Osnovnaya cel' kosmicheskogo eksperimenta "Kepler" - poisk planet u blizhaishih zvezd po izmeneniyu ih bleska v hode prohozhdeniya planety po disku zvezdy. NASA predpolagaet issledovat' bolee 100,000 zvezd spektral'nyh klassov F, G i K za 4 goda nablyudenii. Kepler smozhet poluchat' fotometriyu zvezd s tochnost'yu 90 mikro-zvezdnyh velichin (9x10-5zv.velichiny) pri 15 minutnoi ekspozicii.
Effekt mikrolinzirovaniya deistvuet v storonu protivopolozhnuyu zatmeniyu (prohozhdeniyu), t.e. ne oslablyaet, a usilivaet blesk zvezdy. No obychno dlya planet etim effektom mozhno prenebrech' - iz-za togo, chto razmer zvezdy velik i usilivaetsya (linziruetsya) izluchenie tol'ko ot nebol'shoi chasti ee poverhnosti. Drugoi prichinoi yavlyaetsya to, chto sami planety perekryvayut chast' potoka usilivaemogo izlucheniya, esli oni raspolozheny blizko k zvezde. Odnako, esli zvezda v sisteme kompaktna (v pervuyu ochered' ei mozhet byt' goryachii belyi karlik) i/ili planeta raspolozhena dostatochno daleko, to effekt mikrolinzirovaniya mozhet okazat'sya sushestvennym i dazhe perekryt' ospablenie iz-za prohozhdeniya.

Na etih apparatah budet vestis' spektral'nyi poisk tak nazyvaemyh "biomarkerov" - takih kak O2, O3, H2O, CO i CH4 - v atmosferah takih planet. Nalichie etih gazov ukazyvaet na prisutstvie zhizni na planete ili, po krainei mere, na vozmozhnost' ee kolonizacii. V etom eksperimente takzhe budut vyyasnyat'sya takie parametry planet, kak ih radius, temperatura poverhnosti, nalichie l'da na poverhnosti, period vrasheniya, sushestvovanie sezonov.
Nalichie rastitel'nosti podobnoi zemnoi mozhet byt' vyyavleno
po tak nazyvaemomu "krasnomu krayu" (red edge) primerno na 700 nm.
Eta detal' otlichaetsya ot vseh izvestnyh atomnyh i molekulyarnyh
spektral'nyh osobennostei. Bolee podrobno etot vopros
rassmatrivaetsya v stat'e

Opisan eksperiment BaR-SPOrt. Pro SPOrt my uzhe rasskazyvali. Eto ital'yansko-rossiiskii proekt dlya MKS po issledovaniyu reliktovogo izlucheniya. BaR-SPOrt - eto balonnyi eksperiment, na kotorom ustanovlena analogichnaya apparatura.
Stat'ya korotkaya, no pri etom dovol'no tehnicheskaya.
Kogda sobirayutsya puskat' "sharik" neponyatno.
Odnako, priyatno, chto delo dvizhetsya.

Seriya statei pro sputnik MAP (astro-ph/0301159, astro-ph/0301160, astro-ph/0301164).
Opisyvayutsya razlichnye detali ustroistva sputnika, ego naznachenie i t.d. i t.p. Naibolee obshaya i dostupnaya stat'ya - astro-ph/0301158. V svyazi so skorym opublikovaniem pervyh dannyh s etogo sputnika stat'ya budet nebezinteresna vsem interesuyushimsya sovremennoi kosmologiei.

Kogda-to sovetskii korrespondent sprosil Pele, kogda, po ego mneniyu, SSSR budet chempionom mira po futbolu. Pele otvetil: "Kogda Braziliya budet chempionom mira po hokkeyu". Ostroumno, no erunda, vse-taki my byli pervymi chempionami Evropy .... Odnako, vot Braziliya sobiraetsya rentgenovskii sputnik delat' (predpolagaemyi zapusk 2007/8). Pora by i nam hot' Spektr-RG zapustit'. A to stydno...

V stat'e opisyvaetsya proekt novogo sputnika. Plany svyazany s ochen' uspeshnoi missiei Rossi X-Ray Timing Explorer (RXTE), izyuminka kotoroi zaklyuchalas' v vysokom vremennom razreshenii. Schitaetsya, chto dlya sushestvennogo progressa novyi instrument dolzhen prevoshodit' staryi na poryadok (rech' idet o progresse v smysle "nepredskazuemy" t.n. serendipicheskih otkrytii). Tak ono i est' v dannom sluchae.
Osnovnye prognoziruemye zadachi sputnika takovy: izuchenie kvaziperiodicheskih oscillyacii (osobenno bystryh oscillyacii ot kandidatov v chernye dyry) i millisekundnye oscillyacii v rentgenovskih vspleskah (barsterah). Odnako yasno, chto etim delo ne ogranichitsya.
Avtor setuet, chto v proshedshem desyatiletii bylo vsego dve amerikanskie rentgenovskie missii (Chandra i RXTE), a potomu vazhno delat' eshe i eshe.... Budem nadeyat'sya, chto proekt poluchit podderzhku.

Koncepciya novogo kosmicheskogo eksperimenta, kotoryi budet zanimat'sya spektroskopiei vysokogo razresheniya (E/dE~6000) na granice rentgenovskogo i ul'trafioletovogo diapazonov. Obsuzhdayutsya nablyudatel'nye zadachi.
