. Space Adventures was one of the first players in the commercial space sector. Eric Anderson founded the company in 1998; since 2001, he’s sent seven clients on eight successful trips to the International Space Station. Among those who have placed $5 million deposits on future orbital spaceflights is Sergey Brin, the cofounder of Google. The company plans to start offering flybys of the Moon in 2017, at a cost of $150 million per trip.

. The Commercial Orbital Transportation Services (COTS) program was NASA’s effort to develop America’s capacity to resupply the International Space Station. The program ran from January 2006 to September 2013 and awarded $500 million to SpaceX and Orbital Sciences Corporation. This is less than the cost of a single Space Shuttle flight, so NASA considers the program a great success. See

. The asteroid initiative was originally dressed up with the idea of helping to protect the Earth from future impacts, but the rock that can be captured is far too small to be relevant to that problem. There are a lot of unknowns in the mission concept, and that typically translates into a great deal of unplanned time and money. See NASA’s web page on the concept at http://www.nasa.gov/mission_pages/asteroids/initiative/.

. China has progressed rapidly in science and technology because of a buoyant economy and strong investment. But a less noble reason is a shameless willingness to plagiarize intellectual property and to reverse engineer cutting-edge technologies. They have done this with fighter aircraft and supercomputers and they are now doing it with space technology.

8
. The simple calculation of the equilibrium temperature at the surface of a terrestrial planet depends only on the luminosity of the star and the distance to the planet. If the orbit is too eccentric or elliptical, a planet may move in and out of the habitable zone over the course of its year. Atmospheric gases raise the surface temperature—strongly in the case of greenhouse gases like carbon dioxide and methane—and that shifts the habitable zone out to larger distances.

. Abel Mendez at the University of Puerto Rico has used quantitative measures of planetary habitability to evaluate locations in the Solar System. The measures are keyed to the survival of primary producers like plants, phytoplankton, and microbes in general. Habitability can and will evolve as the atmospheric and geological conditions change. In the Solar System, Mendez found Enceladus to have the best subsurface habitability, followed by Mars, Europa, and Titan. For a summary, see the

. A large amount of technical and scientific information about the Kepler mission and its goals is on the NASA website: http://www.kepler.arc.nasa.gov/.

16
. In 2014, Kepler got a new lease on life when engineers figured out how to use the pressure of starlight and tiny thruster burns to maintain the spacecraft orientation. It’s not as precise as the original pointing, so Kepler can no longer detect Earths, but it can find planets around a wide range of star types over a wide swath of sky. The so-called K2 mission will last about two years.
