Coronavirus: Please be aware it may take us slightly longer to respond than usual. Find out about our coronavirus response and current contact hours. The space race between the USA and Russia started with a beep from the Sputnik satellite exactly 60 years ago October 4, and ended with a handshake in space just 18 years later.

The handshake was the start of many decades of international collaboration in space. But over the past decade there has been a huge change. The space environment is no longer the sole preserve of government agencies. Private companies have entered the exploration domain and are propelling the sector forward more vigorously and swiftly than would be the case if left to governments alone. It could be argued that a new space race has begun, in which private companies are competing against each other and against government organisations.

But this time it is driven by a competition for customers rather than the urge to show dominance by being first to achieve a certain goal. So who are the main players and how will they change the science, technology and politics of space exploration?

What is immediately apparent is that practically all these companies are based in the US. There is a big difference between building and launching satellites into low Earth orbit for telecommunications and sending crew and cargo to the International Space Station ISS and beyond. Private companies in several nations have been engaged in the satellite market for many years.

Their contributions to the development of non-governmental space exploration has helped to lay the trail for entrepreneurs with the vision and resources to develop their own pathways to space. Today, several companies in the US are looking very specifically at human spaceflight. The main goals of all three companies is to reduce the cost of access to space — mainly through reuse of launchers and spacecraft — making space accessible to people who are not specially trained astronauts.

One thing these companies have in common is the private passion of their chief executives. SpaceX was founded in by Elon Musk, a charismatic entrepreneur, engineer, inventor and investor. To this end, the company has specialised in the design, manufacture and launch of rockets, providing direct competition to the United Launch Alliance between Boeing and Lockheed Martin that had been the contract holder of choice for launch of NASA and Department of Defense rocket launches.

Its success has been spectacular. Having developed the Falcon 9 launch vehicle and Dragon spacecraft , it became the first commercial company to dock a spacecraft at the ISS in The firm now has a regular run there, carrying cargo.

But so far, no astronauts. However, the Falcon Heavy is comparable to the Saturn 5 rocket that launched the Apollo astronauts, and SpaceX has designed its vehicle with a view to sending astronauts to the moon by , and to Mars as early as This would replace the Falcon and Dragon spacecraft — and would not only transport cargo and explorers to the moon and Mars, but could also reduce travel times between cities on Earth.

Musk calculates it could take as little as 29 minutes to fly from London to New York. Whether the company succeeds in sending astronauts to the moon in remains to be seen. Either way, a lot could be going on then — is also the year when Blue Origin, founded in by Jeff Bezos , the technology and retail entrepreneur behind Amazon, aims to launch people to space. But its ambition is different from that of SpaceX.

Blue Origin is focusing on achieving commercially available, sub-orbital human spaceflight — targeting the space tourism industry. The rocket then descends back to Earth, with the engines firing towards the end of the descent, allowing the spacecraft to land vertically. Test flights with no passengers have made successful demonstrations of the technology. The trip to space and back will take about 10 minutes. Founded in by Richard Branson , also a technology and retail entrepreneur, it plans to carry six passengers at a time into sub-orbital space and give them about six minutes of weightlessness in the course of a two and a half hour flight.

The technology differs from that of SpaceX and Blue Origin in that the launch into space is not from the ground, but from a jet airplane. This mothership flies to an altitude of about 18km about twice as high as regular aircraft fly and releases a smaller, rocket-powered spacecraft SpaceShip Two which is propelled to an altitude of about km.

The programme has been delayed by technical difficulties — and then by the tragic loss of pilot Mike Alsbury , when SpaceShip Two exploded in mid-air during a test flight in No date is yet set for the first passengers to fly. The aim of the prize is to launch a robotic mission to the moon, place a lander on the surface and drive 50 metres, sending back high-quality images and video. The competition is still in progress. Five privately funded teams must launch their spacecraft to the moon by the end of The changes are taking place against a backdrop of tried and tested international collaboration in space, which took off in earnest at the end of the space race.

Throughout the s and s, the US and Russia space programmes complemented each other beautifully — though perhaps not intentionally. Following the cessation of Apollo in , the US space programme focused its efforts on robotic exploration of the solar system. Messenger orbited Mercury and Magellan orbited Venus. When New Horizons launched to Pluto in , it was a mission to visit the last planet left unexplored in the solar system.

Pluto as seen by New Horizons. Russia, on the other hand, pursued the goal of human spaceflight, with its incredibly successful Mir orbiting space station and its programme of flights to transfer cosmonauts and cargo backwards and forwards to Mir.

The list of nations that contribute to the ISS continues to grow. The shuttle programme finished in and, since its successor Orion built in collaboration with European Space Agency, ESA is not due to come into service until at least , the international community has been reliant on Russia to keep the ISS fuelled and inhabited.

The European Space Agency was established just two months before the historic handshake of , following many years of independent aeronautical engineering research by individual nations. Similarly, the Chinese, Japanese and Indian space agencies can trace their heritages back to the s.

A number of smaller countries including the United Arab Emirates also have ambitious plans. Of course these countries also compete against each other. There has been widespread speculation that the entry of China into the field was sufficient to introduce a fresh imperative to the US space programme.

China has a well-developed space programme and is currently working towards having a space station in orbit around the Earth by about China has also had three successful missions to the moon. China also has a declared intent of landing taikonauts on the moon by — the same time frame in which the US will be testing its new Orion spacecraft in orbit around the moon. Indeed, space exploration may even act as a buffer zone from international politics, which is surely something worth having.

It will be interesting to see how a wider role in space exploration for private companies will affect such international collaborations, especially since so much of the effort is based in the USA.

A benefit of the entry of the private sector into space exploration has been recognition of the high-tech companies that contribute to the growth of the economy as valuable targets for investment. Contributors to the conference included NASA — but overwhelmingly the speakers were from private technology and investment companies.

And that is another aspect of the explosion of interest in space commerce and tourism. Laws, statutes and other regulations are necessary to govern the international nature of space exploration.

At the moment, the United Nations, through its Office for Outer Space Affairs , is responsible for promoting international cooperation in the peaceful uses of outer space. It also oversees operation of the Outer Space Treaty , which provides a framework for the governance of space and activities that might take place. The operation is designed along similar lines to the international treaties that oversee maritime activities and the exploration of Antarctica.

This is the closest that there is to international legislation and, since coming into operation in with the three inaugural signatories of the United States of America, the United Kingdom and the then USSR, the treaty has been signed by countries including China and North Korea.

It is necessary to have such controls because although the risks that surround space exploration are high, potential rewards are even higher. If we look at the way more conventional businesses operate, such as supermarkets, competition drives prices down, and there is little reason to believe that competition between space companies would follow a different model.

In which case, greater risks might be taken in order to increase profitability. There is no evidence for this so far — but as the field develops and additional private companies move into space exploration — there will be a higher probability of accident or emergency. The treaty says that a state launching a probe or satellite is liable to pay compensation for damage when accidents occur.

However, the costs of space exploration are astronomical and crippling to poorer countries, making them increasingly depend on commercial launchers.

But if a private company launches an object that subsequently causes damage in space, the struggling economy will have to pick up the bill. The treaty may therefore need to be updated to make private companies more liable. There are also serious issues around the safety of astronauts, who have the legal right to a safe existence when in outer space. Looking to the future, there will be a need for an expanded version of a Civil Aviation Authority, directing and controlling routes, launches and landings on Earth, and between and on planetary bodies.

All the safety and security considerations of air and sea travel will pertain to space travel at a vastly enhanced level, because the costs and risks are so much higher. There will have to be firm and well-understood protocols in the event of a spacecraft crashing, or two spacecraft colliding. Not to mention piracy or the possibility of hijack. All this might sound a little gloomy, taking the dash and exhilaration from space exploration, but it will be a necessary development that opens up the era of space travel for citizens beyond those with deep pockets.

The original space race resulted from the ideas and skills of visionary theoretician engineers including: Robert H Goddard , Wernher von Braun , Konstantin E. Is it too far a stretch to think that the second space race is propelled by a new generation of entrepreneurs, including Bezos, Branson and Musk?

If this is the situation, then I would hope that the main enabling factor in the pursuit of space endeavours is not possession of wealth, but that vision, ingenuity and a wish for the betterment of human are the main driving forces.

Present needs, capabilities, and future prospects in rocket technology for space research

Non-rocket spacelaunch refers to concepts for launch into space where much of the speed and altitude needed to achieve orbit is provided by a propulsion technique that is not subject to the limits of the rocket equation. As a result, launch costs are a large percentage of the cost of all space endeavors. If launch can be made cheaper, the total cost of space missions will be reduced. Due to the exponential nature of the rocket equation, providing even a small amount of the velocity to LEO by other means has the potential of greatly reducing the cost of getting to orbit. Launch costs in the hundreds of dollars per kilogram would make possible many proposed large-scale space projects such as space colonization , space-based solar power [3] and terraforming Mars. In this usage, the term "static" is intended to convey the understanding that the structural portion of the system has no internal moving parts.

In recent years scientists have investigated a series of new methods for non-rocket space launch, which promise to revolutionize space launches and flight. Such new methods include the gas tube method, cable accelerators, tether launch systems, space elevators, solar and magnetic sails, circle launcher space keepers and more.

It is the first Indian launch vehicle to be equipped with liquid stages. After its first successful launch in October , PSLV emerged as the reliable and versatile workhorse launch vehicle of India with 39 consecutively successful missions by June During period, the vehicle has launched 48 Indian satellites and satellites for customers from abroad. Besides, the vehicle successfully launched two spacecraft — Chandrayaan-1 in and Mars Orbiter Spacecraft in — that later traveled to Moon and Mars respectively. It can take up to 1, kg of payload to Sun-Synchronous Polar Orbits of km altitude. The third stage of PSLV is a solid rocket motor that provides the upper stages high thrust after the atmospheric phase of the launch.

Убирайся отсюда немедленно, или я вырву эту булавку из твоих ноздрей и застегну ею твой поганый рот. Парень побелел. Беккер попридержал его еще минутку, потом отпустил. Затем, не сводя с него глаз, нагнулся, поднял бутылки и поставил их на стол.

Игра в шарады закончилась. Дело принимает совсем дурной оборот. - Итак, кольцо взял немец. - Верно. - Куда он делся. - Понятия не имею. Я побежал позвонить в полицию.

 У дверцы лифта есть код, - злорадно сказала Сьюзан. - Ну и проблема! - засмеялся Хейл.  - Думаю, коммандер мне его откроет. Разве не так, коммандер. - Ни в коем случае! - отрезал Стратмор. Хейл вскипел: - Послушайте меня, старина. Вы отпускаете меня и Сьюзан на вашем лифте, мы уезжаем, и через несколько часов я ее отпускаю.

 Да. Первая неделя оказалась последней. Солнечный удар и инфаркт. Бедолага. Беккер ничего не сказал и продолжал разглядывать пальцы умершего. - Вы уверены, что на руке у него не было перстня.
