Amit Kshatriya, a decorated Indian-American software and robotics engineer was appointed as the first head of NASA’s newly-established Moon to Mars Programme that will help the agency ensure a long-term lunar presence needed to prepare for humanity’s next giant leap to the Red Planet.

Kshatriya will serve as NASA’s first head of the office, with immediate effect, the agency announced on Thursday.

The new office aims to carry out the agency’s human exploration activities on the Moon and Mars for the benefit of humanity, a NASA press release said.

“The golden age of exploration is happening right now, and this new office will help ensure that NASA successfully establishes a long-term lunar presence needed to prepare for humanity’s next giant leap to the Red Planet,” said NASA Administrator Bill Nelson.

“The Moon to Mars Programme Office will help prepare NASA to carry out our bold missions to the Moon and land the first humans on Mars,” Nelson explained.

The new office resides within the Exploration Systems Development Mission Directorate, reporting to its Associate Administrator Jim Free, it said.

As directed by the 2022 NASA Authorisation Act, the Moon to Mars Programme Office focuses on hardware development, mission integration and risk management functions for programmes critical to the agency’s exploration approach that uses Artemis missions at the Moon to open a new era of scientific discovery and prepare for human missions to Mars, according to the press release.

This includes the Space Launch System rocket, Orion spacecraft, supporting ground systems, human landing systems, spacesuits, Gateway, and more related to deep space exploration.

The new office will also lead planning and analysis for long-lead developments to support human Mars missions, it said.

In his new role, Kshatriya will be responsible for programme planning and implementation for human missions to the Moon and Mars.

Kshatriya directed and provided leadership and integration for the Space Launch System, Orion, and Exploration Ground Systems programmes, as well as associated Artemis Campaign Development Division initiatives linking the agency’s Moon to Mars objectives, it said.

Previously, Kshatriya served as the acting deputy associate administrator for the Common Exploration Systems Development Division.

Kshatriya began his career in the space programme in 2003, working as a software engineer, robotics engineer, and spacecraft operator primarily focused on the robotic assembly of the International Space Station.

From 2014 to 2017, he served as a space station flight director, where he led global teams in the operations and execution of the space station during all phases of flight.

In 2021, he was assigned to NASA Headquarters in the Exploration Systems Development Mission Directorate as an assistant deputy associate administrator, where he was an integral part of the team that returned a spacecraft designed to carry humans to the Moon during the Artemis I mission.

Son of first-generation Indian immigrants to the US, Kshatriya holds a Bachelor of Science in Mathematics from the California Institute of Technology in Pasadena, California, and a Master of Arts in Mathematics from The University of Texas at Austin.

Kshatriya was born in Brookfield, Wisconsin, but considers Katy, Texas, to be his hometown.

He was decorated with the NASA Outstanding Leadership Medal for actions as the lead flight director for the 50th expedition to the space station, as well as the Silver Snoopy — an award that astronauts bestow for outstanding performance contributing to flight safety — for his actions as lead robotics officer for the Commercial Orbital Transportation Services Dragon demonstration mission to the orbiting laboratory, the release added.

A Nearby Supernova May End Dark Matter Search, Claims New Study

The pursuit of understanding dark matter, which comprises 85 percent of the universe’s mass, could take a significant leap forward with a nearby supernova. Researchers at the University of California, Berkeley, led by Associate Professor of Physics Benjamin Safdi, have theorised that the elusive particle known as the axion might be detected within moments of gamma rays being emitted from such an event. Axions, predicted to emerge during the collapse of a massive star’s core into a neutron star, could transform into gamma rays in the presence of intense magnetic fields, offering a potential breakthrough in physics.

Potential Role of Gamma-Ray Telescopes

The study was published in Physical Review Letters and revealed that the gamma rays produced from axions could confirm the particle’s mass and properties if detected. The Fermi Gamma-ray Space Telescope, currently the only gamma-ray observatory in orbit, would need to be pointed directly at the supernova, with the likelihood of this alignment estimated at only 10 percent. A detection would revolutionise dark matter research, while the absence of gamma rays would constrain the range of axion masses, rendering many existing dark matter experiments redundant.

Challenges in Catching the Event

For detection, the supernova must occur within the Milky Way or its satellite galaxies—an event averaging once every few decades. The last such occurrence, supernova 1987A, lacked sensitive enough gamma-ray equipment. Safdi emphasised the need for preparedness, proposing a constellation of satellites, named GALAXIS, to ensure 24/7 sky coverage.

Axion’s Theoretical Importance

The axion, supported by theories like quantum chromodynamics (QCD) and string theory, bridges gaps in physics, potentially linking gravity with quantum mechanics. Unlike neutrinos, axions could convert into photons in strong magnetic fields, providing unique signals. Laboratory experiments like ABRACADABRA and ALPHA are also probing for axions, but their sensitivity is limited compared to the scenario of a nearby supernova. Safdi expressed urgency, noting that missing such an event could delay axion detection by decades, underscoring the high stakes of this astrophysical endeavour.

Fastest-Moving Stars in the Galaxy May be Piloted by Aliens, New Study Suggests

Intelligent extraterrestrial civilisations might be utilising stars as massive interstellar vehicles to explore the galaxy, according to a theory proposed by Clement Vidal, a philosopher at Vrije Universiteit Brussel in Belgium. His research suggests that alien species could potentially accelerate their binary star systems to traverse vast cosmic distances. While such a concept is purely hypothetical and unproven, Vidal’s recent paper, which has not undergone peer review, raises intriguing possibilities about advanced extraterrestrial engineering.

Concept of Moving Star Systems

The study was published in the Journal of the British Interplanetary Society. As per a report by LiveScience, the idea revolves around the notion that alien civilisations, instead of building spacecraft for interstellar travel, might manipulate entire star systems to travel across the galaxy. Vidal highlights binary star systems, particularly those involving neutron stars and smaller companion stars, as ideal candidates. Neutron stars, due to their immense gravitational energy, could serve as anchors for devices designed to propel the system by selectively ejecting stellar material.

Vidal explained in the paper that uneven heating or manipulation of magnetic fields on a star’s surface could cause it to eject material in one direction. This process would create a reactionary thrust, propelling the binary system in the opposite direction. The concept provides a way to travel while preserving planetary ecosystems, making it a theoretically viable method for species reliant on their home systems.

Known Examples with High Velocities

Astronomers have identified hypervelocity stars, such as the pulsars PSR J0610-2100 and PSR J2043+1711, which exhibit high accelerations. While their movements are believed to be natural phenomena, Vidal suggests they could be worth further investigation to rule out potential artificial influences.

This theory adds an unconventional angle to the search for intelligent life, expanding possibilities beyond traditional methods of exploration like searching for signals or probes. The research underscores the importance of considering advanced and unconventional methods aliens might employ to navigate the galaxy.

Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis

NASA’s Hubble Space Telescope has provided new insights into the young star FU Orionis, located in the constellation Orion. Observations have uncovered extreme temperatures in the inner region of its accretion disk, challenging current models of stellar accretion. Using Hubble’s Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph, astronomers captured far-ultraviolet and near-ultraviolet spectra, revealing the disk’s inner edge to be unexpectedly hot, with temperatures reaching 16,000 kelvins—almost three times the Sun’s surface temperature.

A Star’s Bright Outburst Explained

First observed in 1936, FU Orionis became a hundred times brighter in months and has remained a unique object of study. Unlike typical T Tauri stars, its accretion disk touches the stellar surface due to instabilities. These are caused by the disk’s large mass, interactions with companion stars, or material falling inwards. Lynne Hillenbrand, a co-author from Caltech, in a statement said that the ultraviolet brightness seen exceeded predictions, revealing a highly dynamic interface between the star and its disk.

Implications for Planet Formation

As per a report by NASA, the study holds significant implications for planetary systems forming around such stars. The report further quoted Adolfo Carvalho, lead author of the study, saying that while distant planets in the disk may experience altered chemical compositions due to outbursts, planets forming close to the star could face disruption or destruction. This revised model provides critical insights into the survival of rocky planets in young star systems, he further added.

Future Investigations on FU Orionis

The research team continues to examine spectral emission lines in the collected data, aiming to map gas movement in the star’s inner regions. Hillenbrand noted that FU Orionis offers a unique opportunity to study the mechanisms at play in eruptive young stars. These findings, published in The Astrophysical Journal Letters, showcase the ongoing value of Hubble’s ultraviolet capabilities in advancing stellar science.
