Misija sonde New Horizons u slikama (HQ)

Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard NASA’s New Horizons spacecraft, taken on July 13, 2015, when the spacecraft was 476,000 miles (768,000 kilometers) from the surface. This is the last and most detailed image sent to Earth before the spacecraft’s closest approach to Pluto on July 14. The color image has been combined with lower-resolution color information from the Ralph instrument that was acquired earlier on July 13. This view is dominated by the large, bright feature informally named the “heart,” which measures approximately 1,000 miles (1,600 kilometers) across. The heart borders darker equatorial terrains, and the mottled terrain to its east (right) are complex. However, even at this resolution, much of the heart’s interior appears remarkably featureless—possibly a sign of ongoing geologic processes. CREDIT: NASA/APL/SwRI

 

Danas (14.7.2015.) u 13:49 je NASA-ina sonda New Horizons uspješno prošla na tek 12,5 tisuća kilometara od Plutona, patuljastog planeta koji je od Zemlje (u prosjeku) udaljen oko šest milijardi kilometara, čime se upisala u povijest istraživanja svemira

O koliko se golemoj udaljenosti radi, pokazuje i podatak da radio signali koje New Horizons neumorno odašilje prema Zemlji, a koji putuju brzinom svjetlosti (300.000 kilometara u sekundi), do naše planete putuju oko 5.5 sati. Usporedbe radi, svjetlosti treba oko osam minuta i 20 sekundi kako bi došla od Sunca do Zemlje.

Sonda New Horizons lansirana je 19. siječnja 2006. te je ujedno najbrža letjelica koju je čovječanstvo ikad lansiralo, pa tako od zadnjeg gašenja motora prema Plutonu putuje nevjerojatnom brzinom od 58.536 km/h (16,26 km/s).
