Voyager 2 Entering Interstellar Space

This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.

NASA's Voyager spacecraft has detected an increasing amount of cosmic rays. About 5% increase is detected by the sensor on Voyager to compared to last month.

Cosmic rays come from outer space which means Voyager 2 is ready to enter into Interstellar space soon. The same increase in cosmic rays was detected by Voyager 1 before it entered into Interstellar space, but it took more than three months to enter into interstellar space after detection. NASA is expecting more exposure to cosmic rays by Voyager 2.

Voyager 2 is probably at the rim of the heliosphere and will exit it soon. Since 2007 the Voyager 2 is in the outer rim of the heliosphere.

Voyager 2 started its journey in 1997 from NASA's Jet Propulsion Laboratory based in California. Since then it has traveled 11 billion miles ( 17.7 billion kilometers ) from Earth, more than 118 times the distance between Earth and the Sun.

Voyager Project Scientist Ed Stone said
"We're seeing a change in the environment around Voyager 2, there's no doubt about that We're going to learn a lot in the coming months, but we still don't know when we'll reach the heliopause. We're not there yet -- that's one thing I can say with confidence."
However, Voyager team member says that cosmic rays is not a definite sign that probe is entering the Interstellar space because the heliopause moves inward and outward during the Sun's 11-year activity cycle. Solar activity refers to emissions from the Sun, including solar flares and eruptions of a material called coronal mass ejections. During the 11-year solar cycle, the Sun reaches both a maximum and a minimum level of activity.

Stephen Hawking's Final Book gives brief Answers to Big Questions

Stephen Hawking's final work was launched by his children on Monday which discuss issues from Existence of God to Time Travel and other big questions. His children completed his final book after he died last year.

Stephen started his book last year to answer the common question which he encountered many times from public. The title of the book is ''Brief Answers to Big Questions''.

His daughter, Lucy Hawking, said he was regularly asked for such question and this book contains his clear and most authentic answers. We all wish he was here to see it published, she added.

What are these big questions and what did he write answers to them?


Is there a God?How Did it All Began?What is inside a black hole?Can we predict the future?Is Time Travel possible?Will we survive on Earth?Is there any other intelligent life in Universe?Should we colonize space?How do we shape the future?Multiple challenges Stephen Hawking says the simplest explanation is that God does not exist and…

Russia Trying to Bring back Extinct Animals

A research facility is being settled in a region of Russia by Vladimir Putin at 4th Economic Eastern Forum which aims to study the remains and clone extinct animals like woolly mammoth, woolly rhinoceros, cave lion and breeds of long-gone horses of old times.





The investment sought for this project is 5.9Million USD.

The animals which could weight 6000 kg have been disappeared from that territory about 4 thousands years ago.

About 80% of the samples of the extinct animals with preserved tissue have been found in this region Siberia .  







Human flights to ISS will begin in 2019

NASA has confirmed that manned space flight will be carried by SpaceX and Boeing in the mid of 2019.SpaceX rocket for ISS will depart in June 2019 while Boeing spacecraft will go in August 2019.
It will be the first US mission since the retirement of the shuttle in 2011.NASA's astronauts are currently using Russian made Soyuz spacecraft and its contract will end in June 2019.NASA said on 4th of the October that it will give monthly updates 


Phil McAlister who is the director of commercial flights in NASA said in Blog that 

New Updates schedule is better but launch schedule may be uncertainHe also said these are new spacecraft and lot of engineering work has to be done before take off.

Back in 2014 both the SpaceX and Boeing received $6.8bn from NASA to build spacecraft that will take humans to ISS.

Boeing has said they will be ready for Orbital Flight Test in March 2019.
The Success of this manned space shuttle will be a great achievement of the commercial space industry, and NASA will …
