The Space Race is Once Again Heating Up But This Time Nations Aren't the Only Ones Involved
Several interesting space announcements have made headlines in the last couple of weeks. Among them:
- Russia is once more putting money into their space program with plans to develop new rockets, and cooperate with ESA on robotic missions to Mars,
- NASA announces partnerships with agencies and private companies, and open competition to accelerate the development of space technology,
- Two commercial space ventures announce asteroid mining plans.
Russia's Revived Space Program
The Russian announcements indicate that Roscosmos intends to make a significant new investment, 2.1 trillion rubles (almost $70 billion U.S.) between now and 2020. Some of that money will be allocated to building a new delivery system for human space flight to replace the Soyuz capsule and launch vehicle. Russia's Soyuz and R-7 rocket have been the backbone of their human space program for 50 years. And today Soyuz remains the primary way flight crews get to and leave the International Space Station (ISS). Russia's launch capability started to show cracks with the loss of one Soyuz resupply vessel in August 2011, leading to the delay of subsequent flight crew missions. Although sketchy on details, Russia plans to have a new propulsion system and transportation module ready for testing by 2018 with full deployment for human space missions by 2020.
Russia is also getting back into the business of sending robotic spacecraft to the Moon and Mars. The first new Moon mission in 42 years is planned for 2015 and will be followed by others over the next five years. Russia is opening a new space city called Cosmodrome Vostochny and the first Luna-Glob will be sent to the Moon from there. The launcher will continue to be the same as those currently used for Soyuz missions. The Luna-Glob will test a new surface landing system. Russian scientists have chosen six lunar landing sites for future missions. And one planned for 2017 will be a joint Russian-Indian module called Luna-Resurs. For Mars where Russia and its predecessor, the Soviet Union, have had little success, the next effort to get to the planet will be a joint one with ESA planned to arrive in 2016. This will be followed by a joint effort to land a rover like Curiosity in 2018. And ultimately Russia intends to send humans to the Moon to establish a lunar base (see image below).
NASA Finds Partnership Works for Them
NASA and ESA signed an agreement this month calling for ESA to build the service module for Orion, the space capsule touted for future Deep Space missions with humans aboard. The service module hardware seen in the artist rendering below will include propulsion, power, thermal control, water, air and other essential supplies for supporting the crew and capsule. The first Orion test flight is scheduled for 2014 with plans to send an unmanned capsule 5,800 kilometers (3,600 miles) into space. The service module will get its first test in 2017 when NASA plans to send the first Space Launch System (SLS) rocket in an unmanned flight to circle the Moon and return to Earth. Human flights to the Moon and back on Orion are currently scheduled for 2021 with flights to Near Earth Asteroids (NEA) planned for the mid-2020s. Add this announcement to last weeks when NASA awarded Bigelow Aerospace a substantial contract to supply the ISS with an inflatable module and NASA recent awarding of contracts to three other private space ventures and you can see a picture emerging of how the agency intends to achieve its Near Earth and Deep Space goals.
NASA also announced this month a call for its Innovative Advanced Concepts Program (NIAC) seeking proposals from academia and industry to achieve new breakthroughs in aerospace technology. They plan to fund 15 proposals covering technologies for shielding spacecraft from radiation, developing ocean exploration technologies on Earth that could be exported for use on Moons like Europa, improved air purification systems for space capsules, and new methods of propulsion and power systems for operating space capsules. NIAC currently limits these opportunities to U.S. citizens and organizations based in the U.S. In 2012 NIAC funded 28 proposals each receiving between $100,000 and $500,000.
Mining Asteroids Competition Heating Up
Asteroids, often seen as the space junk left over when the Solar System organized itself into the Sun, planets and dwarf planets, are the target of two commercial ventures, each planning to mine and harvest these rocks in space. Some months ago I wrote about Planetary Resources with its ambitious plan to launch 5 space telescopes to search out asteroids suitable for exploitation. The first of these will be launched in 2014. By 2016 probes will land and do assay work sending samples and data from asteroids back to Earth. Mining would begin in 2022. Backed by some major billionaire entrepreneurs including Larry Page and Eric Schmidt from Google, and James Cameron, the film producer, to name three, the venture intends to harvest valuable materials like iron, nickel, water, and platinum from these space rocks, generating billions in revenue.
But Planetary Resources are no longer the only team at play among the more than 10,000 asteroids already mapped of which 1,700 are deemed potentially rich in assets worth exploiting. The competition, Deep Space Industries (DSi). This week the company announced its plan to launch a number of spacecraft given the name FireFly, to do asteroid prospecting. DSi is taking a different approach. Each Firefly is a CubeSat, a small (25 kilogram or 55 pound), low-cost satellite that will piggyback with launches of telecommunication satellites. Each FireFly mission is designed to last from 2-6 months. The FireFly missions will be followed in 2016 by DragonFly launches. These 32 kilogram (70 pound) spacecraft seen in the artist depiction below will bring back between 27 and 68 kilograms (60 to 150 pounds) of samples harvested from selected asteroids. See the image of what DSi's first targets will be Earth-crossing asteroids seen as easier to reach than the Moon and as potential threats to Earth should one strike the planet. A 50-meter (165 feet) in diameter asteroid could weigh more than 200,000 tons composed of 20% iron-nickel. In some cases DSi plans to move asteroids to make them easier to harvest but it will only do this with rocks less than 30 meters in diameter (less than 100 feet) that are Earth crossing. Asteroids of this size should they accidentally enter the Earth's atmosphere would break up and burn out in the atmosphere.
Both companies see much of what they produce being used to help build a space economy focused on space construction from habitats at LaGrange points or on the surface of the Moon and Mars, to materials for building Earth and Solar System satellites. Only a small percentage will actually be sent to Earth.
