Kepler-10, formerly known as KOI-72, is a Sun-like star in the constellation of Draco that lies 173 parsecs (564 light years) from Earth.
 Kepler-10 was targeted by NASA's Kepler spacecraft, as it was seen as the first star identified by the Kepler mission that could be a possible host to a small, transiting exoplanet.
 The star is slightly less massive, slightly larger, and slightly cooler than the Sun; at an estimated 10.4 billion years in age, Kepler-10 is almost 2.6 times the age of the Sun.
 Kepler-10 is host to a planetary system made up of at least two planets.
 Kepler-10b, the first undeniably rocky planet, was discovered in its orbit after eight months of observation and announced on January 10, 2011.
 The planet orbits its star closely, completing an orbit every 0.8 days, and has a density similar to that of iron.
 The second planet, Kepler-10c, was confirmed on May 23, 2011, based on follow-up observations by the Spitzer Space Telescope.
 The data shows it has an orbital period of 42.3 days
Kepler-24d is a transiting exoplanet orbiting the star Kepler-24, located in the constellation Cygnus.
 It was discovered by the "Kepler" telescope in February 2014.
 It orbits its parent star at only 0.138 astronomical units away, and at its distance it completes an orbit once every 19 days.
CoRoT-13b is a transiting exoplanet found by the CoRoT space telescope on 12 July 2010.
Akari (ASTRO-F) is an infrared astronomy satellite developed by Japan Aerospace Exploration Agency, in cooperation with institutes of Europe and Korea.
 It was launched on 21 February 2006 at 21:28 UTC (06:28, 22 February JST) by M-V rocket into Earth sun-synchronous orbit.
 After its launch it was named "Akari" (明かり), which means "light" in Japanese.
 Earlier on, the project was known as IRIS (InfraRed Imaging Surveyor).
The Transiting Exoplanet Survey Satellite (TESS) is a planned space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method.
 It is planned for launch in March 2018.
Kepler-24d is a transiting exoplanet orbiting the star Kepler-24, located in the constellation Cygnus.
 It was discovered by the "Kepler" telescope in February 2014.
 It orbits its parent star at only 0.051 astronomical units away, and at its distance it completes an orbit once every 4.244384 days.
Gliese 581g , unofficially known as Zarmina (or Zarmina's World), is an unconfirmed (and frequently disputed) exoplanet claimed to orbit within the Gliese 581 system, twenty light-years from Earth.
 It was discovered by the Lick–Carnegie Exoplanet Survey, and is the sixth planet orbiting the star; however, its existence could not be confirmed by the European Southern Observatory (ESO) / High Accuracy Radial Velocity Planet Searcher (HARPS) survey team, and its existence remains controversial.
 It is thought to be near the middle of the habitable zone of its star.
 That means it could sustain liquid water—a necessity for all known life—on its surface, if there are favorable atmospheric conditions on the planet.
ViaSat-2 is a commercial communications satellite launched June 1, 2017.
 Once in service in early 2018, it will be the world's highest capacity communications satellite with a throughput of 300 Gbit/s, succeeding EchoStar XIX launched in December 2016.
 It is the second Ka-band satellite launched by ViaSat after ViaSat-1.
 The satellite will provide satellite internet through Exede Internet to North America, parts of South America, including Mexico the Caribbean, and to air and maritime routes across the Atlantic Ocean to Europe.
Sentinel-2A is a European optical imaging satellite launched in 2015.
 It is the first Sentinel-2 satellite launched as part of the European Space Agency's Copernicus Programme.
 The satellite carries a wide swath high-resolution multispectral imager with 13 spectral bands.
 It will perform terrestrial observations in support of services such as forest monitoring, land cover changes detection, and natural disaster management.
Sentinel-1A is a European radar imaging satellite launched in 2014.
 It is the first Sentinel-1 satellite launched as part of the European Union's Copernicus programme.
 The satellite carries a C-band Synthetic Aperture Radar which will provide images in all light and weather conditions.
 It will track many aspects of our environment, from detecting and tracking oil spills and mapping sea ice to monitoring movement in land surfaces and mapping changes in the way land is used.

Question: Which satellite launched first, the Transiting Exoplanet Survey Satellite or Akari?
Answer: Akari
