This animation features actual satellite images of the far side of the moon, illuminated by the sun, as it crosses between the DSCOVR spacecraft’s Earth Polychromatic Imaging Camera (EPIC) and telescope, and the Earth - one million miles away.
Currently, NASA’s plans for Mars remain under evaluation with the internal Design Reference Mission (DRM) process.
Nonetheless, a large amount of work is now beginning to take place via the Human Architecture Team (HAT) evaluations, laying the foundations on the huge challenges associated with sending humans to Mars – and returning them safely.
The specific roadmap is still some years away. However, the likelihood of “Phobos First” continues to be referenced in NASA documentation.
The international team of researchers made the discovery by observing a brown dwarf 20 light years away using both radio and optical telescopes. Their findings provide further evidence that suggests these stars act more like supersized planets.
While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer. The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 percent brighter and has a diameter 10 percent larger.
STS-114 was the Shuttle mission that returned NASA to active flight status following the tragic loss of Columbia. But STS-114, more than any other flight of its time, endured significant changes in the wake of the Columbia Accident Investigation Board’s recommendations and helped pave the way for a safe and successful conclusion to the Shuttle Program.
still among the things i’m most proud to have ever worked on
