One month after its launch, the Transiting Exoplanet Survey Satellite (better known as TESS) goes through the moon on its way to the study of exoplanets. This point is not casual, but totally determinant for the mission, and as proof that everything is going to be space wind aft we have the first photo of TESS testing one of its cameras.
From the mission we talked a little about its launch: on April 18, 2018, we would see it flying through the air thanks to a Falcon 9 rocket from Space X to take the Kepler witness. A mission for which there is a system with four fully equipped wide-angle cameras whose breakdown is very interesting.
Centaur, di potato
Not long ago we remember the importance of the Moon for the approach of missions that involve reaching beyond it, but beyond that, it can be a future service station for rockets is the gravitational pull that it can provide. Specifically is what is known as gravitational assistance, and is a way to save fuel and accelerate taking advantage of the movement of a star (in this case, the Moon).
NASA confirmed that TESS has already come to greet and take an appetizer in the form of an impulse 5,000 miles from the Moon (8,050 kilometers). He did it last Thursday, May 17 and the mission team took the opportunity to do a photographic test using one of the four cameras that the space observatory assembles.
The test image made by TESS using one of its cameras. What you see: more than 200,000 stars that are divided between the Centaur constellation and the Coalsack nebula among other regions. The bright spot at the bottom is the Beta Centauri star. The image, centered on the southern constellation Centaurus, reveals more than 200,000 stars. (Credit: NASA / MIT / TESS )
