New discovery of cracked mud on Mars has scientists hopeful for possible signs of life

Mars Curiosity Rover

  • It is a S. robotic vehicle designed to explore the surface of Mars.
  • It was launched aboard an Atlas V rocket from Cape Canaveral Air Force Station, Florida on Nov. 26, 2011, and landed on Aug. 5, 2012, after taking eight months and 10 days to reach the Red Planet.
  • The rover is currently roaming Mars'' landscape looking for signs of life and learning about the Red Planet''s unique environment.
  • The rover is part of NASA''s Mars Science Laboratory mission which tested a novel landing method that saw the spacecraft descend on a parachute before its landing system fired up its rockets and hovered as the rover was lowered down onto the surface.
  • Features:
    • It is about 3 metres long and weighs about 900 kg.
    • It does not rely on solar cells for its energy needs but rather draws its electric power from a thermoelectric power generator, with the heat source being the radioactive decay of plutonium and the heat sink being Mars’s atmosphere.
  • According to NASA, Curiosity has four main science goals in support of the agency''s Mars exploration program:
    • Determine whether life ever arose on Mars.
    • Characterize the climate of Mars.
    • Characterize the geology of Mars.
    • Prepare for human exploration.

NASA’s Perseverance rover

  • Main Job: Seek signs of ancient life and collect samples of rock and regolith (broken rock and soil) for possible return to Earth.
  • The rover will collect samples of rock and soilencase them in tubes, and leave them on the planet''s surface to be returned to Earth at a future date.
  • Launch: It was launched on July 30, 2020from Cape Canaveral, Florida.
  • LandingSuccessfully landed on the surface of Mar''s Jezero Crater on Feb. 18, 2021.
  • Features:
    • It is about 3 metres long, 2.7 metres wide, and 2.2 metres tall.**
    • It is about the size of a car, but weighs only about 1,025 kilograms with all instruments on board.
    • Power source: Multi-Mission Radioisotope Thermoelectric Generator (MMRTG). Converts heat from the radioactive decay of plutonium into electricity.

Course Correction Keeps Parker Solar Probe on Track for Venus Flyby

Parker Solar Probe

  • It is a NASA spacecraft designed to study the Sun and its atmosphere.
  • It was launched on August 12, 2018, from Cape Canaveral Air Force Station, Florida, and is currently orbiting the Sun in a highly elliptical orbit that takes it closer to the Sun than any previous spacecraft.
  • The mission objectives of the Parker Solar Probe are to study the structure and dynamics of the Sun''s corona, the Sun''s magnetic field, and the solar wind.
  • To achieve this, the probe will make a total of 24 close approaches to the Sun over the course of its mission, getting as close as 3.83 million miles from the Sun''s surface, which is about 7 times closer than any previous spacecraft.
  • In December 2021, the Parker Probe reached the atmosphere of the sun. Since then, it’s been looping around the sun, drawing closer each time, and sending back tons of data about everything it encounters.
  • Features:
    • Mass685 kilograms at launch.
    • Scientific InstrumentsFields Experiment (FIELDS), Integrated Science Investigation of the Sun (ISIS), Wide Field Imager for Solar Probe (WISPR), Solar Wind Electrons Alphas and Protons (SWEAP).
    • Parker Solar Probe and its instruments are protected from the Sun by a 4.5-inch-thick (11.43 cm) carbon-composite shield, which can withstand temperatures reaching nearly 2,500 degrees Fahrenheit (1,377 Celsius).

Index of Industrial Production

  • It is one of the Prime indicators of economic development for the measurement of trends in the behavior of Industrial Production over a period of time with reference to a chosen base year.
  • It indicates the relative change of physical production in the field of industries during a specified year as compared to the previous year.
  • It is computed and published by the National Statistical Office (NSO) on a monthly basis.
  • Base Year:
    • The base is always given a value of 100.
    • The current base year for the IIP series in India is 2011-12.
    • So, if the current IIP reads as 116, it means that there has been 16% growth compared to the base year.

IIA scientists discover star that challenges previous understanding of star formations

Carbon-Enhanced Metal-Poor (CEMP) star

  • The researchers used high-resolution spectroscopic data acquired using High Dispersion Spectrograph (HDS) attached to SUBARU telescope (Japan) to analyze the star''s surface chemical composition.
  • The team found that the iron content of the star is thousand times less than that of the sun and it is heavily enriched with neutron-capture elements.
  • The star which defies previous classifications and challenges previous understanding of star formation processes shows signs of having been formed through the combination of two different neutron-capture processes - the slow (s-) and intermediate (i-) neutron-capture processes.
  • It can help understand how different star formation processes influence the elemental composition of stars.
  • Elements beyond iron are created due to reactions in nuclear astrophysics called neutron capture processes.
  • The slow (s-) process is believed to occur in low-mass stars during the asymptotic giant branch (AGB) phase and the rapid (r-) process is believed to occur in Supernovae and Neutron Star mergers.
  • One of the proposed sites for intermediate (i-) process is low-metallicity low-mass AGB stars.
  • Understanding the relative contributions of these processes to the elemental composition of stars is important for understanding the chemical evolution of galaxies and the origins of the elements in the universe.

Carbon-enhanced metal-poor (CEMP) star:

  • These stars are characterized by diverse heavy elements abundance patterns and are primarily classified into four groups, based on which groups of heavy elements are more abundant.
  • These are mostly dwarf stars, sub-giant stars, or giant stars, and stars that belong to these evolutionary stages cannot produce elements heavier than iron.

Bunch of new Placenta in chip devices can help making pregnancies safe

Placenta on chip

  • A bunch of devices mimicking the placenta at various stages of pregnancy can help in drug discovery, study of toxicity of chemicals like caffeine, and understanding the effects of conditions such as preeclampsia and diabetes mellitus during pregnancy.
  • In pregnancy, the placenta shields the baby from harmful drugs and chemicals. But some can still cross this barrier and cause harm to the baby in the womb.
  • Thus, pregnant women are not given most medications and they continue to suffer. Determining which medicines can be given during pregnancy that would not cross the placenta is a daunting task.
  • Researchers have used microfluidic technology which can integrate processes, to create an environment that represents basic organ structure and functions of the placenta.
  • The placenta in a lab dish developed by the team allows different cells to interact with each other, incorporate mechanical properties and mimic the blood flow, which closely resembles the in-vivo condition.
  • Among various available POC models, these devices are more suitable for probing placental development as well as diseases caused due to defects in the placenta. Also, patient-specific sample screening will be possible for personalised medicine.

Advantage of placenta-on-chip

  • It will enable early detection of adverse conditions and allows researchers and healthcare professionals to observe, study, and identify potential issues that may arise during pregnancy.
  • It enables the study of placental function, detection of complications, personalized medicine, and the development of new therapies.
