Chandrayaan 2 Latest News And Updates: All You Need to Know

science news

Chandrayaan 2 is one of the most ambitious space programs of ISRO. After the success of Mars Orbiter, the hopes have been really high. Chandrayaan 2 almost did what it was supposed to do, i.e, the Lander landed on the dark, unseen side of the moon. But since then, all contacts have been lost, but not our hopes. All efforts are being made, not only by ISRO but also by NASA to get back in touch with the Lander. Here we have everything about this thrilling space program of exploring the unseen side of the moon. So, let’s start from the beginning.

How is Chandrayaan 2 different from its predecessor Chandrayaan 1?

Chandrayan 1Chandrayaan 2
Orbiter- 100 Kms from the Lunar SurfaceOrbiter- 100 Kms from the Lunar Surface
Vikram Lander- to land softly near the south pole.
Payloads- 11

  • India- 5
  • Europe- 3
  • USA- 2
  • Bulgaria- 1
Payloads- 13, all Indian along with 1 Passive Experiment

Launched in 2008, it was a PSLV with the spacecraft mass of 1.4TLaunched on July 22, 2019, it is a GSLV MKIII with the spacecraft mass of 3.8T.

Chandrayaan 2 latest news and updates so far:

May 15, 2019

On this day ISRO released the benefits of Chandrayaan 2.

  • ISRO believes that the clues to the answers to some extremely fundamental questions related to our Solar System are hidden in the hills, craters, and valleys of the Moon. Their study might unravel these mysteries.
  • It will inspire the whole nation to use science and technology in real-life applications.
  • It will unleash innovation, resulting in future R&D.
  • Chandrayaan 2 will expand India’s footprints in Space.
  • It will open doors to exploring more Economic possibilities.

ISRO explained the challenges there are to landing on the Moon.

  • The non-uniform gravity of the Earth and Moon, Moon’s true Orbital motion, the gravitational pull of other astronomical bodies and solar radiation pressure makes it hard to maintain the trajectory accuracy while navigating such a large distance.
  • Heavy background noises make the deep-space communication weak.
  • Moon keeps changing its location due to the orbital motion, hence the intersection of its path with Chadrayaan-2 must be predicted well in advance with utmost accuracy.
  • The uneven mass distribution under the surface of the Moon makes its gravity lumpy. And since it influences the orbit of the spacecraft, orbiting around the moon becomes a challenge.
  • Soft landing on moon is yet another challenge.
  • Firing the onboard engines close to the lunar surface might cause the lunar dust to disrupt the working and performance of the spacecraft.
  • Vacuums and extreme temperatures also make it hard to function on the lunar surface without facing challenges.
