NASA will soon provide advanced training to Indian astronauts to send a joint mission to the International Space Station this year or shortly thereafter, US envoy to India Eric Garcetti has said. Garcetti made these remarks while speaking at the “US-India Commercial Space Conference: Unlocking Opportunities for US & Indian Space Startups,” hosted by the US-India Business Council (USIBC) and the US Commercial Service (USCS) in Bengaluru on Friday.

“NASA will soon provide advanced training to Indian astronauts, with the goal of mounting a joint effort to the International Space Station, hopefully, this year or shortly thereafter, which was one of the promises of our leaders’ visit together,” Garcetti said.

“And soon we will launch the NISAR satellite from ISRO’s Satish Dhawan Space Center to monitor all resources, including ecosystems, the Earth’s surface, natural hazards, sea level rise, and the cryosphere,” Garcetti said, according to a USIBC press statement issued here.

NISAR is a joint Earth-observing mission between NASA and the Indian Space Research Organisation (ISRO).

“You see whether it’s the pursuit of peace and the peaceful use of space, things like the Artemis Accord, we are hand in hand, arm in arm. When it comes to prosperity and jobs, which is a big part of this conference today, it can be produced by startups in this sector, good-paying, high-tech jobs for Indians and for Americans. Space is right there,” Garcetti said.

The Artemis Accords lay out a framework for collaborating nations’ safe exploration of the moon and beyond.

The day-long event in Bengaluru saw the participation from senior officials from both the US and Indian governments, including Garcetti, Indian Space Research Organisation (ISRO) Chairman Dr. S Somanath, representatives from the National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), and the Government of India, as well as prominent leaders from the commercial space industry, industry stakeholders, venture capitalists, and market analysts.

“I must salute the visionary leadership that we have in both nations in India and the US for engaging in such an accord which looks at the moon as a sustainable place for all of us to come and work together,” Somnath said in his remarks.

“The connection between the Indian partners and also the US partners in critical technologies and specifically in the space sector is really becoming stronger. And I’m very happy about that type of engagement and the options available to the industries and the US business indigenous to connect with India in the emerging space sector as well,” he said.

Expressing optimism about the prospects of US-India collaboration in space, USIBC president Atul Keshap described it as a new chapter in the US-India space partnership. This week has been particularly fruitful, with USIBC and USCS joining forces to champion these two iCET space deliverables, he said.

“The conference highlights the deepening synergy between our two free nations in pioneering space exploration and innovation by the leading democracies. Through strategic alliances and collaborative efforts, we’re on the brink of achieving extraordinary milestones and expanding the horizons of space exploration beyond what we once imagined,” Keshap said.

The US-India Commercial Space Conference underscores the importance of fostering strategic partnerships to drive innovation and propel the space industry forward,” said USIBC managing director Alexander Slater.

“This is the next step in USIBC’s continued commitment to fostering bilateral cooperation among leading companies and startups from both countries to unlock new opportunities for economic growth, job creation and technological leadership. It builds on our work in February when we hosted the second edition of INDUS-X in New Delhi, which promoted similar opportunities for innovation and cooperation in new and emerging defence technologies,” he said.

Meanwhile, senior defence officials from India and the US have met in Washington to discuss opportunities to strengthen space cooperation and identified potential areas for collaboration with the American industry.

Meeting for the second annual US-India Advanced Domains Defence Dialogue (AD3), the officials discussed a wide range of bilateral cooperation.

The American team was led by Vipin Narang, Acting Assistant Secretary of Defence for Space Policy, and the visiting Indian delegation was led by Vishwesh Negi, India’s Joint Secretary for International Cooperation.

During this year’s Dialogue, Narang and Negi discussed opportunities to strengthen space cooperation and identified potential areas for collaboration with US industry, said Department of Defence Spokesperson Cmdr. Jessica Anderson.

Among a group of US and Indian defence officials, the two co-chaired the first US-India principal-level tabletop discussion that explored areas to enhance cooperation in the space domain.

They agreed to advance AD3 through regular working group discussions.

The visiting Indian Government delegation also engaged with the US Space Command, the Joint Commercial Operations Cell, and artificial intelligence experts from across the US Department of Defence, Anderson said.

NASA's TRACERS Mission Rescheduled for 2025 to Explore Solar Wind and Earth's Magnetic Field

NASA has refocused its Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) launch date to no earlier than 2025 to provide more time for the mission crew to prepare. This mission is about a pair of satellite studying about how the solar wind, interacts with and enters Earth’s magnetosphere, the region around Earth dominated by our planet’s magnetic field. Understanding and eventually forecasting how energy from our Sun enters our planet and may affect assets depending on space and the earth depends on research into this interaction.

Mission Objectives

According to NASA, the TRACERS spacecraft will launch on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The twin spacecraft will travel around 341 miles above the planet through polar cusps, a short area of the earth’s magnetic field where solar wind is concentrated and funneled into our atmosphere.

In order to investigate the location and frequency of a phenomena known as magnetic reconnection near the outer borders of Earth’s magnetic field, the TRACERS mission will fly across the northern polar cusp many times each day.

The explosive energy transfer where two magnetic fields meet, particularly in the magnetopause region where the solar wind meets Earth’s magnetosphere is termed as magnetic reconnection . This event can cause solar wind particles to enter the atmosphere at high speeds, igniting the northern and southern lights but also creating hazardous conditions for astronauts and satellites, damaging ground infrastructure, communication signals, and aviation.

Mission oversight

David Miles is leading this TRACERS mission at the University of Iowa and it is managed by the Southwest Research Institute in San Antonio. The Heliophysics Division at NASA Headquarters in Washington oversees the project through the Heliophysics Explorers Program Office at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. As part of the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) contract, the launch service is being provided by NASA’s Launch Services Program, which is headquartered at the agency’s Kennedy Space Center in Florida, in collaboration with NASA’s Science Mission Directorate.

NASA’s McClain and Ayers Finish Historic EVA, Advance ISS Solar Upgrade

NASA astronauts Anne McClain and Nichole Ayers completed the fifth all-female spacewalk, moving an antenna and partially preparing the International Space Station for a new set of solar arrays on May 1st. Their 5-hour, 44-minute extravehicular activity was completed after re-entering the Quest airlock, and it started to get re-pressurised. McClain and Ayers completed the majority of their goals. However, they had to postpone some of the chores until a later spacewalk since they were behind schedule and had limited supplies.

About the mission

According to NASA, Expedition 73 crewmates Anne McClain and Nichole Ayers began working at 9:05 a.m. EDT (1305 GMT) by carrying tools and equipment out to the port (or left) side of the space station’s backbone truss. They began assembling the attachment hardware for the seventh pair of International Space Station Rollout Solar Arrays, or IROSA. These will be installed once they arrive on a SpaceX Dragon commercial resupply services mission later this year.

Installing smaller, more efficient solar arrays will increase electricity generation by up to 30%, increasing the station’s total power from 160 to 215 kilowatts. The spacewalkers constructed and installed the right struts and the upper triangle of the mast canister modification kit before being told to tidy up their workstations and proceed to the next, more important assignment.

Continuing the Legacy of Female Spacewalkers

It was Ayers’s first spacewalk and McClain’s third. McClain has spent 18 hours and 52 minutes away from the space station. Rotating astronaut crews have continuously staffed the ISS since November 2000. This was the 93rd EVA from the U.S. Quest airlock and the 275th overall to assist the ISS’s installation, maintenance, and upgrading.

In October 2019, NASA astronauts Christina Koch and Jessica Meir conducted the first all-female EVA. In January 2020, the pair performed two further spacewalks together. In November 2023, NASA’s Jasmin Moghbeli and Loral O’Hara completed a walk alone.

New Study Challenges Signs of Life on Exoplanet K2-18b

New Study Challenges Signs of Life on Exoplanet K2-18b

Expectations were high at the start of this month when a group of University of Cambridge astronomers reported they had found the “strongest evidence yet” of life on an exoplanet called K2-18b. Their assertions sprang from the detection of dimethyl sulphide (DMS), a gas linked to biological activity in the atmosphere of Earth. Conducted using the James Webb Space Telescope (JWST), the finding suggested that the planet may be a watery, habitable world. But a detailed examination of the facts now begs grave doubt about the veracity of their bold assertions.

Skepticism Grows Over K2-18b Life Claims Amid New Analysis and Calls for More Data

As per a  study posted on April 22, Jake Taylor of the University of Oxford applied a neutral statistical test that detected no clear molecular signatures in the JWST data, just a flat line. The studies suggest the signal is either noisy or too weak to provide strong conclusions. The first Cambridge-led study revealed a three-sigma DMS detection much below the five-sigma threshold usually required to prove major scientific discoveries. Critics also questioned the absence of supporting compounds like ethane and claimed the models employed may have exaggerated DMS levels.

Astrobiologists Eddie Schwieterman and Michaela Musilova note that current evidence doesn’t meet strict criteria for proving life; thus, there is a need for multiple independent teams to analyse the same dataset.

Further complicating matters, new research indicates K2-18b may orbit too close to its star to retain liquid water, possibly excluding it from the habitable zone. Adding to the scepticism, DMS was recently detected on a cold comet, suggesting that such molecules can exist without life. Lead author of the original research, Madhusudhan, has supported the findings but discounted Taylor’s test as too simple and “irrelevant” for their assertions.

Most scientists agree that confirmation or denial of DMS existence in K2-18b’s atmosphere depends on additional solid, peer-reviewed research. The argument is still in progress, an ongoing narrative illustrating how science develops not by certainty but by questioning and correction.
