'''Kendaraan peluncur''' biasanya adalah [[kendaraan]] bertenaga [[roket]] yang dirancang untuk membawa muatan (pesawat antariksa berawak maupun kargo tidak beraak atau [[satelit]]) dari permukaan Bumi atau atmosfer bawah ke luar angkasa. Bentuk yang paling umum adalah [[roket multitahap]] berbentuk rudal balistik, tetapi istilahnya lebih umum dan juga mencakup kendaraan seperti [[Pesawat Ulang Alik]]. Sebagian besar kendaraan peluncur beroperasi dari [[landasan peluncuran]], didukung oleh [[Pusat kendali misi|pusat kendali]] peluncuran dan sistem seperti perakitan dan pengisian bahan bakar kendaraan. Kendaraan peluncur direkayasa dengan aerodinamika dan teknologi canggih, yang berkontribusi pada biaya operasi yang tinggi.
Kendaraan peluncur orbital harus mengangkat muatannya setidaknya ke batas ruang angkasa, sekitar 150 km (93 mil) dan mempercepatnya ke kecepatan horizontal setidaknya 7.814 m/s (17.480 mph). Kendaraan suborbital meluncurkan muatannya ke kecepatan yang lebih rendah atau diluncurkan pada sudut elevasi yang lebih besar dari horizontal.
Kendaraan peluncur orbital praktis menggunakan [[propelan]] [[kimia]] seperti [[bahan bakar padat]], [[Kriogenik (bahan bakar)|kriogenik]] temperatur rendah [[hidrogen cair]], [[minyak tanah]], [[metana cair]], [[oksigen cair]], atau propelan [[Hipergolik (propelan)|hipergolik]] yang mudah terbakar karena reaksi.
=== Kendaraan peluncur methalox ===
Penggunaan metana cair dan oksigen cair sebagai propelan terkadang disebut propulsi methalox. Metana cair memiliki impuls spesifik yang lebih rendah daripada hidrogen cair, tetapi lebih mudah disimpan karena titik didih dan kepadatannya yang lebih tinggi, serta tidak mudah rapuh. Metana cair juga meninggalkan lebih sedikit residu di mesin dibandingkan dengan minyak tanah, yang bermanfaat untuk penggunaan ulang.
Metana cair yang dimurnikan dan juga [[LNG]] digunakan sebagai bahan bakar [[propelan]] [[Kriogenik (bahan bakar)|kriogenik]] [[temperatur]] rendah [[roket]], bila dikombinasikan dengan [[oksigen cair]], seperti pada mesin [[TQ-12]], [[BE-4]], [[SpaceX Raptor|Raptor]], dan [[YF-215]]. Karena kesamaan antara metana dan LNG, mesin-mesin tersebut umumnya dikelompokkan bersama di bawah istilah [[methalox]].
Sebagai bahan bakar roket cair, kombinasi metana/oksigen cair menawarkan keuntungan dibandingkan kombinasi [[minyak tanah]]/oksigen cair, atau [[kerolox]], dalam menghasilkan molekul-molekul gas buang kecil, mengurangi [[kokas]] atau pengendapan [[jelaga]] pada komponen-komponen mesin. Metana lebih mudah disimpan daripada [[hidrogen]] karena [[titik didih]] dan kepadatannya yang lebih tinggi, serta tidak adanya kerapuhan hidrogen. [[Berat molekul]] gas buang yang lebih rendah juga meningkatkan [[Fraksi mol|fraksi]] [[energi panas]] yang berupa [[energi kinetik]] yang tersedia untuk [[Propulsi wahana antariksa|propulsi]], sehingga meningkatkan [[impuls spesifik]] roket. Dibandingkan dengan hidrogen cair, energi spesifik metana lebih rendah tetapi kekurangan ini diimbangi oleh kepadatan dan kisaran suhu metana yang lebih besar, yang memungkinkan tangki yang lebih kecil dan lebih ringan untuk [[massa]] bahan bakar tertentu. Metana cair memiliki kisaran suhu (91–112 K) yang hampir sesuai dengan oksigen cair (54–90 K). Bahan bakar ini saat ini digunakan dalam kendaraan peluncur operasional seperti [[Zhuque-2]] dan [[Vulcan (roket)|Vulcan]] serta peluncur yang sedang dikembangkan seperti Starship, Neutron, dan [[Terran R]].
Karena keuntungan yang ditawarkan bahan bakar metana, beberapa penyedia peluncuran ruang angkasa swasta bertujuan untuk mengembangkan sistem peluncuran berbasis metana selama tahun 2010-an dan 2020-an. Persaingan antarnegara ini dijuluki sebagai Perlombaan Methalox menuju Orbit, dengan roket methalox [[Zhuque-2]] milik LandSpace menjadi yang pertama mencapai orbit.
Pada Januari 2024, dua roket berbahan bakar metana telah mencapai orbit. Beberapa roket lainnya sedang dalam tahap pengembangan dan dua upaya peluncuran orbital gagal:
* Zhuque-2 berhasil mencapai orbit pada penerbangan keduanya pada 12 Juli 2023, menjadi roket berbahan bakar metana pertama yang berhasil melakukannya. Roket ini gagal mencapai orbit pada penerbangan perdananya pada 14 Desember 2022. Roket yang dikembangkan oleh LandSpace ini menggunakan mesin TQ-12.
* Vulcan Centaur berhasil mencapai orbit pada percobaan pertamanya, yang disebut Cert-1, pada 8 Januari 2024. Roket yang dikembangkan oleh [[United Launch Alliance]] ini menggunakan mesin [[BE-4]] milik [[Blue Origin]], meskipun tahap kedua menggunakan hydrolox RL10.
* Terran 1 mengalami kegagalan dalam upaya peluncuran orbital pada penerbangan perdananya pada 22 Maret 2023. Roket yang dikembangkan oleh Relativity Space ini menggunakan mesin Aeon 1.
* Starship mencapai orbit transatmosfer pada penerbangan ketiganya pada 14 Maret 2024, setelah dua kali gagal. Roket yang dikembangkan oleh SpaceX ini menggunakan mesin Raptor.
[[SpaceX]] mengembangkan mesin Raptor untuk wahana peluncur superberat Starship. Mesin ini telah digunakan dalam uji terbang sejak 2019. SpaceX sebelumnya hanya menggunakan RP-1/LOX pada mesin mereka. Blue Origin mengembangkan mesin BE-4 LOX/LNG untuk New Glenn dan United Launch Alliance [[Vulcan Centaur]]. BE-4 akan menghasilkan daya dorong sebesar 2.400 kN (550.000 lbf). Dua mesin penerbangan telah dikirim ke ULA pada pertengahan tahun 2023.
Pada bulan Juli 2014, Firefly Space Systems mengumumkan rencana untuk menggunakan bahan bakar metana untuk kendaraan peluncur satelit kecil mereka, Firefly Alpha dengan desain mesin aerospike.
[[ESA]] sedang mengembangkan mesin roket methalox Prometheus 980kN yang diuji coba pada tahun 2023.
== Jenis kendaraan peluncuran ==
Peluncuran kendaraan, kendaraan peluncur khususnya orbital, memiliki minimal dua tahap, tetapi kadang-kadang sampai 4.
=== Dengan platform peluncuran ===
* Darat: Spaceport dan silo rudal tetap (Strela) untuk dikonversi ICBM
* Laut: Platform tetap (San Marco), platform mobile (Sea Launch), kapal selam (Shtil', Volna) untuk dikonversi SLBM
* Udara: Pesawat (Pegasus, Virgin Galactic LauncherOne, Stratolaunch Sistem), balon (ARCASPACE), JP Aerospace Orbital Ascender, proposal permanen pelabuhan ruang angkasa Buoyant
=== Dengan ukuran ===
Ada banyak cara untuk mengklasifikasikan ukuran kendaraan peluncuran. The Komisi Agustinus yang diciptakan untuk meninjau rencana untuk mengganti Space Shuttle, menggunakan skema klasifikasi berikut:
* '''Roket sonda''' tidak dapat mencapai orbit dan hanya mampu spaceflight sub-orbital.
* '''Kendaraan peluncur angkut ringan''' mampu mengangkut hingga 2.000 kg (£ 4400) dari muatan ke orbit bumi rendah (LEO).
* '''Kendaraan peluncur angkut medium''' mampu mengangkut antara 2.000 sampai 20.000 kg (4.400 sampai £ 44.000) dari muatan ke LEO.
* '''Kendaraan peluncur angkut berat''' mampu mengangkut antara 20.000 sampai 50.000 kg (44.000 sampai £ 110.200) dari muatan ke LEO.
* '''Kendaraan peluncur angkut superberat''' mampu mengangkut lebih dari 50.000 kg (110.200 £ +) dari muatan ke LEO.
== Perakitan ==
Setiap tahap roket individu umumnya dikumpulkan di lokasi pabrik dan dikirim ke lokasi peluncuran; jangka waktu perakitan kendaraan mengacu pada penggabungan tahap roket dengan muatan pesawat ruang angkasa dalam satu kendaraan perakitan yang dikenal sebagai kendaraan ruang angkasa.
Kendaraan tahap tunggal (seperti sounding roket), dan kendaraan multi tahap mulai yang lebih kecil dari berbagai ukuran, biasanya dapat dirakit secara vertikal, langsung di landasan peluncuran dengan mengangkat setiap tahap pesawat ruang angkasa dan secara berurutan di tempat dengan cara diderek.
== Perbandingan sistem peluncur orbital ==

== Persaingan pasar peluncuran antariksa ==
Persaingan pasar peluncuran antariksa merupakan manifestasi kekuatan pasar dalam bisnis penyedia layanan peluncuran. Secara khusus, tren dinamika persaingan di antara kemampuan transportasi muatan dengan harga yang beragam memiliki pengaruh yang lebih besar pada pembelian peluncuran daripada pertimbangan politik tradisional negara pembuat atau entitas nasional yang menggunakan, mengatur, atau memberi lisensi layanan peluncuran.
Setelah munculnya teknologi penerbangan antariksa pada akhir tahun 1950-an, layanan peluncuran antariksa muncul, secara eksklusif oleh program nasional. Kemudian pada abad ke-20, operator komersial menjadi pelanggan penting penyedia peluncuran. Persaingan internasional untuk subset muatan satelit komunikasi dari pasar peluncuran semakin dipengaruhi oleh pertimbangan komersial. Namun, bahkan selama periode ini, untuk satelit komunikasi yang diluncurkan oleh komersial dan entitas pemerintah, penyedia layanan peluncuran untuk muatan ini menggunakan kendaraan peluncur yang dibuat sesuai spesifikasi pemerintah, dan dengan pendanaan pengembangan yang disediakan negara secara eksklusif.
Pada awal tahun 2010-an, lima dekade setelah manusia pertama kali mengembangkan teknologi penerbangan antariksa, sistem kendaraan peluncur yang dikembangkan secara pribadi dan penawaran layanan peluncuran antariksa muncul. Perusahaan kini menghadapi insentif ekonomi, bukan insentif politik seperti pada dekade-dekade sebelumnya. Bisnis peluncuran antariksa mengalami penurunan harga per unit yang drastis, bersamaan dengan penambahan kemampuan yang sama sekali baru, yang membawa babak baru persaingan di pasar peluncuran antariksa.
Pada tahun 2024 dilaporkan bahwa, dengan menghitung semua aktivitas peluncuran dan penerbangan antariksa global, [[SpaceX]], yang memanfaatkan keluarga roket [[Falcon (keluarga roket)|Falcon]] miliknya, telah meluncurkan hampir 87% dari semua upmass di Bumi pada tahun 2023.

<ref name="N6">Encyclopedia Astronautica quotes Energia's "flyaway unit cost" at "$764 million in 1985 dollars". However the realistic exchange rate of Soviet currency was drastically different from the official conversion rate which had been set by decree at 0.8 Soviet rubles per US$1. Unofficially one US dollar in 1980s was in terms of purchasing power roughly equivalent to four Soviet rubles.</ref>
