Christina Hammock Koch is a 41-year-old Engineer and NASA astronaut of the class 2013. She graduated in B.Sc in Electrical Engineering and Physics and M.Sc in Electrical Engineering. She also did the advanced study while working for the Goddard Space flight Center.

Christina blasts off to ISS on 14^th March 2019 and after 328 days she returned to the Earth. “I am so overwhelmed and happy right now,” Koch said just after she slid out from the spacecraft. she orbited Earth 5,248 times, travelling 139 million miles, roughly the equivalent of 291 trips to the Moon and back. She conducted and supported more than 210 investigations, and perhaps most importantly, participated as a research subject. Her record-breaking will help NASA to determine the long term effect of space on a human body. Christina shared her experience on its official tweeter handle “This journey has been everyone’s journey. Thank you to all involved in the success of our mission, and for giving me the opportunity to carry everyone’s dreams into space. I’m filled with gratitude to be back on the planet!”

The 3D image of a crater is captured by the Terrain Mapping Camera-2 which is on the Chandrayaan 2.

The information is officially confirmed by ISRO on the Twitter Account. The ISRO official tweeted “Have a look of 3D view of a crater imaged by TMC-2 of #Chandrayaan2. TMC-2 provides images at 5m spatial resolution & stereo triplets (fore, nadir and aft views) for preparing DEM of the complete lunar surface,”

The triplet images from TMC-2 when processed into Digital Elevation Models, enable mapping of surface landform morphologies. These Includes:

• Craters (formed by impactors)
• Lava tubes (potential sites for future habitability)
• Rilles (furrows formed by  lava channels or collapsed lava tubes)
• Dorsa or wrinkle ridges (formed mostly in Mare regions depicting cooling of and contraction of basaltic lava)
• Graben structures (depicts the structural dislocations on the lunar surface )
• Lunar Domes/ Cones (denoting localized vents of past volcanism on the Moon).

The solar eclipse will be visible in the areas of South America.  The solar eclipse will start at 12:55 pm EDT (10:25 pm Indian standard time) but the solar eclipse won’t happen in India.

What is a Solar Eclipse?

A solar eclipse happens when the Moon lies in between the Sun and the Earth. So the light coming from the Sun is blocked by the Moon which in result causing dark on the areas which come in the path of Moon.  The expected length of this solar eclipse will be double of the last solar eclipse which happened in August 2017.
