Huge reservoir of water under Mars

Seismic data from Mars reveals the presence of a vast underground reservoir of liquid water beneath the surface.

  • Seismic data from NASA's InSight lander- Scientists discovered a large reservoir of liquid water deep under Mars' surface, based on seismic data from NASA’s InSight mission.
  • Significance - The discovery enhances the understanding of Mars' geological history, including its water cycle, crust composition, and mineralogy.
  • Water depth- The water is estimated to reside 7.2 to 12.4 miles (11.5 to 20 km) below the surface, capable of filling an ocean covering Mars globally.
  • Microbial life- Conditions at these depths may have been favorable for microbial life in the past or present.
  • Similar findings on Earth, where microbial life exists underground, suggest the possibility of life in Martian aquifers.
  • Seismic wave analysis- Seismic waves measured by InSight indicated that the rocks in Mars' mid-crust are fractured and filled with liquid water.
  • The new study found that water is embedded in fractured igneous rocks formed by the cooling of magma.

InSight

  • Water on Mars- The presence of water on Mars was confirmed 16 years ago, but the existence of large underground reservoirs of water was hypothesized.

In 2008, NASA's Phoenix lander confirmed the presence of water ice on Mars, marking a pivotal discovery.

  • Mars once had liquid water on its surface, in rivers, lakes, and possibly oceans, over 3 billion years ago.
  • Much of this water may have seeped into the planet's crust rather than escaping into space.
  • Over time, Mars' surface cooled, leaving the water in the form of ice or within its crust.
  • Inaccessibility of water- Although large amounts of water exist in the mid-crust of Mars, it is embedded in small crevices and pores of rocks, located at depths between 11.5 to 20km below the surface.
  • Drilling deep enough to access these water reservoirs is technically difficult.
  • Accessing this water is extremely difficult due to Mars' low gravity and technical challenges in drilling at such depths.
  • Tectonically active regions like Cerberus Fossae may offer alternative sites for accessing subsurface water.
  • Additionally, protecting the Martian environment from contamination remains a major concern for future missions.

NASA's InSight Lander

  • InSight - "Interior Exploration using Seismic Investigations, Geodesy and Heat Transport."
  • Launch- 2018.
  • Objective- NASA's InSight lander was launched to study the deep interior of Mars, focusing on its structure and geological processes.
  • Goal- The primary goal was to explore Mars' interior, including its crust, mantle, and core, through seismic measurements, temperature readings, and radio science experiments.

Monkeypox

Recently, World Health Organization (WHO) declared the Monkeypox or mpox outbreak a public health emergency of international concern amid an outbreak in Congo.

  • Money pox- It is an infectious disease caused by the monkeypox virus.
  • Virus- It is caused by the Orthopoxvirus genus in the Poxviridae family, which includes variola, cowpox, vaccinia, and other viruses.
  • Discovery- It was first discovered in research monkeys in Denmark in 1958.
  • The first human case was reported in a 9-month-old boy in the Democratic Republic of the Congo in 1970.
  • Transmission- Mpox spreads through direct contact with infectious skin, lesions in the mouth or genitals, and contaminated objects like clothing or linens.
  • It can also be transmitted in community settings like tattoo parlors.
  • Symptoms- Appear 1 to 21 days after exposure and include rashes, fever, sore throat, headache, muscle aches, back pain, low energy, and swollen lymph nodes.
  • Diagnosis- It can be diagnosed using polymerase chain reaction (PCR) tests, considered the gold standard.
  • Treatment- There is no specific treatment approved for mpox.
  • Healthcare professionals may treat mpox with some antiviral drugs used to treat smallpox, such as tecovirimat (TPOXX) or brincidofovir (Tembexa).
  • Global Mpox Crisis-The Africa Centers for Disease Control and Prevention (Africa CDC) has declared the ongoing mpox outbreak in Africa as a public health emergency.
  • The World Health Organization (WHO) reported that Sweden is the first country outside of Africa to detect the more lethal mpox strain, clade I.
  • The mpox outbreak involves different strains (clades) of the virus.
    • Clade I, a more deadly variant, is circulating primarily in the Democratic Republic of the Congo (DRC) and neighboring countries.
    • Clade II, the strain from the 2022 outbreak, has been detected in the US but without signs of the more dangerous clade I.
  • More than 27,000 cases and around 1100 deaths have been recorded since January 2023 as the African nation battles its worst-ever outbreak.

Earth Observation Satellite- 08

The Indian Space Research Organisation (ISRO) successfully launched the Earth Observation Satellite (EOS) -08 Earth Observation Satellite.

  • EOS-08- It is a satellite designed for Earth observation and carries advanced technology for various tasks such as disaster monitoring, environmental observation, and surveillance.
  • Launch- Using the Small Satellite Launch Vehicle (SSLV)-D3.

The SSLV is a rocket designed for quick, flexible launches of small satellites (10-500 kg) with minimal infrastructure, can carry multiple satellites simultaneously.

EOS-08

  • Objective- To demonstrate consistent flight performance of the SSLV vehicle systems.
  • To successfully deploy the EOS-08 satellite and SR-0 DEMOSAT into a 475 km circular orbit.
  • Aim- The mission focuses on designing and developing a microsatellite with advanced payload instruments and new technologies for future satellites.
  • Payloads- A total of 3 Payloads

Payload

Features

 

 

 

Electro Optical Infrared Payload
