Ancient Oasis on Mars

NASA finds a new ancient oasis on the red planet, Mars.

The NASA’s Curiosity rover joined the space station since 2012 in research of the Gale crater on the planet Mars.

The scientists from NASA Jet Propulsion Laboratory in California published their journal Nature Geoscience. In this journal, a new study on the Mars water is published lately.

In the recent study with Curiosity rover, “salt enriched rocks” were found at a place known as Sutton Island on Mars. However, these rocks presumably suggest the presence of briny water billions of years ago on Mars.

It is also believed, according to the latest study, that there is a possiblity for the availability of an oasis at the base of the 150-kilometer-wide crater.

Black Hole Sparkles 75 Times Brighter

The Milky Way is a large disk-like space in the galaxy where our solar system is located. This milky way has a heart in its centre with a huge black hole. Recently this black hole lit 75 times brighter than it usually does.

Normally this black hole doesnt shine brighter, except for a dim spark here and there. This sudden blow of brightness upto 75 time more than the usual is noted recently by the astronomers. The reason for this outburst of brightness is not yet discovered.

Scientists at Keck Observatory, Cornell University are looking a way to reveal the mystery.

The rocket was launched exactly at 14:43 local time. This was the second lunar mission initiated by India.

Salient features:

  • This is the first interplanetary expedition in India undertaken by two women: Muthaya Vanitha, the project director and Ritu Karidhal, the mission director
  • Following the cancelation of the first launch countdown (because of technical error caused by helium gas loss from the launch vehicle) the second attempt was more successful
  • Chandrayan-2 was designed to land near the rarely-explored south pole of the moon
  • The main focus will be assessing the availabilitiy of water and mineral content on the lunar soil
  • The lander named Vikram carries a rover, Pragyan, which can travel half a kilometer away from the lander and send images and data
  • The lander is expected to reach moon on 6 or 7 of September after a long journey.

The expedition began today as Olen Kononenko and Alexy Ovchinin, the two Russian cosmonauts step out of the International Space Station.

The cosmonauts came out in their Russian space suit with red and blue strips respectively by 11.42 a.m. EDT for a 6.5 hour spacewalk. The spacewalk was streamed online in the NASA television.

This is Kononenko’s fifth spacewalk expedition and the latters first expedition.

Spring Equinox with a Supermoon

The first day of the spring season is marked as spring equinox. The sun shines straight at the equator. The spring season is to begin on this particular day.

Equinox in Latin means ‘equal day and night’. On this particular day, the day and the night will be equally 12 hours. This day shows the shift in the season and a balance of light shifts between day and night.

This day marks the spring equinox. Whereas, the autumn equinox is expected to occur on September 22. This day is usually used by the astronomers to mark the tropical year. Google doodle has celebrated this day by depicting the spring equinox.

The supermoon is also expected to appear in the sky around 9:45pm on Wednesday. It is expected to come very closer to surface of earth. The moon will appear 14 times larger and 12 times brighter. If one misses this choice he’s gotta wait until 2030 for another supermoon to appear.

The satellite was launched from the European spaceport which was situated in French Guiana. S. Pandian, the director of Satish Dhawan Space Centre (SDSC) represented ISRO in this European space centre Arianespace. He said that it was a flawless launch.

GSAT-31 was sent to replace INSAT-4CR which was dying. GSAT weighs around 2,536 kg with a mission life of 15 years. This was also the first successful launch of the year by the European space station Arianespace.

S. Padian also said that ISRO has been looking forward for another launch of the communication satellite GSAT-30 along with Arianespace around June-July.

ISRO successfully launched PSLV-C44 carrying a military satellite Microsat-R for the Defense Research and Development Oganization (DRDO) on 24 January 2019. It was the first light-weight satellite weighing only 740-kg. The satellite was placed on the 274-km polar sun synchronous orbit.

Another student’s payload, Kalamsat, a satellite of 10-cm size cube weighing only 1.2-kg is the lightest satellite of India. It was designed by the college students and members of Space Kidz India, a Chennai based organization. It was also the first to use the fourth stage of the vehicle, PS4 as its platform.

The countdown for the launch was calculated for 28 hours and the satellite was launched exactly at 11:37 pm.

Chandrayaaan -2 Mission to the Moon in Mid-April : ISRO


   ISRO Chief Dr. K Sivan has announced the space agency’s plans for big missions in the coming days.


He informed that India’s second mission to the moon Chandrayaan-2 will be launched mid-April this year.  

Gaganyaan is a Rs 10,000 crore (Rs 100 billion) project and the space agency has kept a target to conduct the manned mission by December 2021.

Under the Gaganyaan project, India is planning to send three astronauts to outer space for seven days and bring them back.

China Explores the Unexplored Parts of the Moon

China has sent a space vehicle which became the first to explore the farthest area of the moon which was not explored by any human.

China on Thursday sent a space probe vehicle Chang’e-4. It is the robotic space probe mission designed to explore the unexplored area of the moon. Many previous attempts by other countries have failed due to various causes and so Chang’e-4 probe becomes the first to accomplish it.

The probe was fitted with camera to take pictures of the dark side of the moon. Also attempts were to be made to check the geology of the area. The possibility for the existence of the biological organisms were also to be checked by this probe.

It is one of the greatest accomplishment of humans. The search for the unknown is still in progress with full vigour.

Gaganyaan Project On The Go

The Indian Space Research Organization (ISRO) has planned on a manned mission to the spacecraft. This project, named as Gaganyaan has been approved on Friday by the Union Cabinet. According to this approval, the government has planned to provide ₹10,000 crore to the research organisation.

The new project aims to send three astronauts to space. The manned missile is to be sent to set 2 unmanned spacecraft in its postion in space. The crew will stay in the spacecraft nearly for 5-7 days.

The trials for the Gangaayan project will begin by 2020 and the main project will be executed by 2022, said the Union Minister Ravi Shankar Prasasd.
