Vikas Engine is a liquid fueled rocket engine made by India. It was developed by Nambi Narayanan and his team during the 1970′s. It is used in the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) series of expendable launch vehicles for space launch use. It is similar to, the Viking.

The engine is used as the second stage of both the PSLV and the GSLV launch vehicles, with four strap-on boosters. The engine is also capable of swivelling.

If a rocket is launched to deliver a payload from a planetary surface into space it is called a launch vehicle.

There are several broad categories that launch vehicles fall under, including:

* Expendable launch system

* Reusable launch system

* Single stage to orbit

* Two stage to orbit

For the launch vehicles currently in use for human spaceflight, see that article.

There were ca. 46 launches into space in 2004.

Lately Soyuz-U vehicles have been used by the Russian Federal Space Agency mostly with Progress-M robotic cargo spacecraft to resupply the International Space Station (ISS).

The most recent Soyuz-U mission launched Progress M-05M to the ISS on 30 June 2010.

Its most recent non-Progress launch was on 16 April 2010, when a Soyuz-U was used to carry the Kosmos 2462 spacecraft to orbit. As of February 2008, a total of 714 Soyuz-U launch vehicles were launched, with 19 launch failures and 695 successes, making it one of the most reliable launch vehicles ever made.

Mars for Less (MFL) is a proposal for a near-term human Mars expedition that involves the use of existing Evolved Expendable Launch Vehicles (EELVs, or alternatively, Medium-Lift Launch Vehicles, MLLVs). The MFL plan claims that the barrier to entry for a manned Mars mission can be lowered significantly by avoiding development costs in launch vehicles, particularly heavy lift launch vehicles (HLLVs) that many think are required for human space exploration. While more complex than many other mission proposals, Mars for Less has strong economic arguments, including avoiding launch vehicle development costs, and offering the prospect of an anchor tenent for the currently over-supplied launch vehicle market, which could result in reduced launch costs and incentives to develop reusable launch technology. The MFL plan was developed by aerospace engineer Grant Bonin in 2003 when he was a student at Carleton University.

Brazilian space program is the most advanced space program in Iberoamerica, with significant capabilities in launch vehicles, launch sites, and satellite manufacturing. It is based at the National Institute for Space Research (INPE), under the Ministry of Science and Technology (MCT). It was founded by Decree nº. 4.724, on June 9, 2003.

The launch vehicles used in the Soyuz expendable launch system are manufactured at the Progress State Research and Production Rocket Space Center (TsSKB-Progress) in Samara, Russia. As well as being used in the Soyuz programme as the launcher for the manned Soyuz spacecraft, Soyuz launch vehicles are now also used to launch unmanned Progress supply spacecraft to the International Space Station and commercial launches marketed and operated by TsSKB-Progress and the Starsem company. There were 11 Soyuz launches in 2001 and 9 in 2002. Currently Soyuz vehicles are launched from the Baikonur Cosmodrome in Kazakhstan and the Plesetsk Cosmodrome in northwest Russia. Starting in 2010 Soyuz launch vehicles will also be launched from the Guiana Space Centre in French Guiana.

VLS

The VLS – Satellite Launch Vehicle is the Brazilian Space Agency’s main satellite launch vehicle. It is a four-stage rocket composed of a core and four strap-on motors. The vehicle’s first stage has four solid fuel motors derived from the Sonda sounding rockets. It is intended to deploy 100 to 380 kg satellites into 200 to 1200 km orbit, or to deploy 75 to 275 kg payloads into 200 to 1000 km polar orbit. The first 3 prototypes for the vehicle failed to launch, with the 3rd exploding on the launch pad in 2003 resulting in the deaths of 21 AEB personnel. A new version of the launcher is under design with Russian assistance.

Southern Cross program

The Brazilian Space Agency is currently developing a new family of launch vehicles in cooperation with the Russian Federal Space Agency. The five rockets of the Southern Cross family will be based on Russia’s Angara vehicle and liquid-propellant engines.

The program was named “Southern Cross” in reference to the Crux constellation, present on the flag of Brazil and composed of five stars. Hence the names of the future launch vehicles:

*Alpha (light-weight rocket)

*Beta (light-weight rocket)

*Gamma (light-weight rocket)

*Delta (medium-weight rocket)

*Epsilon (heavy-weight rocket)

The first stage of the Gamma, Delta and Epsilon rockets will be powered by a unit based on the RD-191 engine. The second stage, which will be the same for all the Southern Cross rockets, will be driven by an engine based on the Molniya rocket. The third stage will be a solid-propellant booster based on an upgraded version of the VLS-1.

The Gamma launcher is part of the light-weight class, but using the near-equatorial position of the Alcântara Launch Center, it can place almost 1 ton of payload into a GSO.

The Delta launcher is a medium-weight rocket and differs from the Gamma by having four solid-propellant boosters attached to the first stage. Its payload deliverable to a GSO is 1.7 tons.

The Epsilon launcher is a heavy-weight rocket with three identical units attached to the first stage. It can place a four-ton spacecraft in orbit, if it is launched from Alcântara.

The Brazilian government is planning to allocate $1 billion dollars for the project in the next six years. It has already set aside $650 million dollars for the construction of five launch pads able to handle up to 12 launches per year. The program is scheduled to be completed by 2022.
