This artist’s concept illustrates NASA’s Europa Clipper spacecraft as it prepares to orbit Jupiter. The mission, which aims to explore the icy moon Europa for signs of potential habitability, is scheduled for launch on October 10, 2024.


NASA’s Europa Clipper, the agency's largest spacecraft ever built for a planetary mission, is set to embark on an ambitious journey to Jupiter’s moon Europa. Scheduled to launch on October 10, 2024, this mission aims to determine if the icy moon could support life.


Europa Clipper will travel approximately 1.8 billion miles (2.9 billion kilometers) from its launch site at Kennedy Space Center, Florida, to Jupiter. Once there, the spacecraft will orbit the gas giant and conduct 49 close flybys of Europa to gather crucial data about its potential habitability.


Key Mission Details.

  • Potential for Life: Europa is a top candidate for searching for life beyond Earth due to its subsurface ocean, which may contain more water than all of Earth's oceans combined. The mission will investigate whether this ocean has the necessary conditions for life.

  • Radiation Protection: Jupiter’s intense magnetic field creates a harsh radiation environment. Europa Clipper is equipped with a radiation-shielded vault to protect its electronics and has planned orbits to minimize radiation exposure.

  • Frequent Flybys: The spacecraft will perform 49 flybys of Europa during its orbit around Jupiter. Each close encounter will provide data on the moon’s ice shell, ocean, and geology.

  • Advanced Instruments: Europa Clipper carries nine science instruments and a gravity experiment. These instruments will operate simultaneously to deliver comprehensive data on Europa’s composition and structure.

  • Size and Design: At 100 feet (30.5 meters) long with solar arrays deployed, Europa Clipper is NASA’s largest spacecraft designed for planetary exploration. The size is necessary to power its instruments with sufficient sunlight.

  • Journey and Trajectory: The spacecraft’s voyage to Jupiter will span 5½ years. It will use gravity assists from Mars and Earth to accelerate towards its destination.

  • Collaborative Effort: The mission involves contributions from over 1,000 people across the U.S. and Europe, with significant input from institutions such as NASA’s Jet Propulsion Laboratory and the Johns Hopkins Applied Physics Laboratory.

  • Global Participation: Europa Clipper carries a poem by U.S. Poet Laureate Ada Limón, signed by over 2.6 million people worldwide. The spacecraft also features a microchip with waveforms of the word "water" in over 100 languages.


Mission Objectives.


Europa Clipper’s primary goals are to determine the thickness of Europa’s icy shell, understand its interaction with the ocean beneath, investigate the moon’s composition, and characterize its geology. This exploration aims to enhance our understanding of the potential for habitable worlds beyond Earth.


Managed by Caltech’s Jet Propulsion Laboratory in collaboration with several NASA centers, the mission will launch aboard a SpaceX Falcon Heavy rocket from Kennedy Space Center’s Launch Complex 39A.

NASA/ESA Hubble Space Telescope Reveals New Details of the Orion Nebula’s Star Formation.

By Surendra Uikey
  This NASA/ESA Hubble Space Telescope image captures the Orion Nebula (Messier 42, M42), the nearest star-forming region to Earth, located about 1,500 light-years away. A captivating new image captured by the NASA/ESA Hubble Space Telescope offers an extraordinary look into the Orion Nebula, the nearest massive star-forming region to Earth. Located just 1,500 light-years away, this nebula is visible to the naked eye below the three stars forming Orion's "belt." The region is home to hundreds of newborn stars, including two protostars featured in the image: HOPS 150 and HOPS 153. Named after the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory, the protostars HOPS 150 and HOPS 153 provide key insights into the early stages of star formation. HOPS 150, visible in the upper-right corner of the image, is a binary star system, with two young stars orbiting one another. These protostars are surrounded by small dusty disks, where material from th...

New Method Detects Small Asteroids in Main Belt, Offering Insight for Planetary Defense.

By Surendra Uikey
  An international team of physicists, led by MIT researchers, has developed a groundbreaking method to detect small asteroids, as small as 10 meters in diameter, within the main asteroid belt. These space rocks, ranging from the size of a bus to several stadiums wide, were previously undetectable using traditional methods. The team's discovery, detailed in a paper published in Nature, could significantly improve tracking of potential asteroid impactors, aiding planetary defense efforts. The main asteroid belt, located between Mars and Jupiter, is home to millions of asteroids, but until now, scientists could only detect objects roughly a kilometer in diameter. The new detection technique, which utilizes the "shift and stack" method, is able to identify much smaller asteroids, even those far from Earth, enabling more precise orbital tracking. This breakthrough is crucial for planetary defense, allowing scientists to spot near-Earth objects that may pose a threat in the fu...

XSPECT Payload Successfully Validates Performance through Cas A Observation.

By Surendra Uikey
  The XSPECT instrument captures a detailed spectrum of the supernova remnant Cassiopeia A (Cas A), encompassing both the Galactic Cosmic Ray (GCR) background and the Cosmic X-ray Background (CXB). The flux observed above 8 keV predominantly results from the combined contributions of CXB and GCR. The presented spectrum, depicted in the figure, is derived from a cumulative integration time of 20 ksec, collected across multiple orbits, providing valuable insights into the X-ray emissions associated with Cas A. XPoSat, India's inaugural X-ray polarimetric mission, has achieved a significant as the XSPECT instrument captures its initial observations from the Cassiopeia A (Cas A) supernova remnant. Launched on January 1, 2024, XPoSat is equipped with two co-aligned instruments, namely the POLarimeter Instrument in X-rays (POLIX) and X-ray SPECtroscopy and Timing (XSPECT). This mission is designed to unravel the mysteries of cosmic X-ray sources. While POLIX focuses on examining X-ray po...
