NASA’s CLPS Initiative and Contract Details

Reports indicate that NASA’s CLPS programme has engaged multiple commercial partners to facilitate lunar deliveries. Under this framework, Firefly Aerospace was awarded a contract in February 2021 to transport NASA’s payloads to the Moon. The original contract, valued at $93.3 million, was later modified to $101.5 million. CLPS contracts are structured as indefinite-delivery/indefinite-quantity agreements, with a cumulative ceiling of $2.6 billion through 2028. Firefly Aerospace’s lander is among several commercial lunar missions that aim to advance scientific exploration and technological innovation as part of Artemis-era initiatives.

Future Implications of the Artemis Campaign

The Artemis campaign is set to leverage commercial lunar deliveries to conduct experiments, refine technologies, and build capabilities for long-term exploration. According to NASA officials, these efforts will support future Artemis astronaut missions to the Moon and lay the groundwork for eventual crewed expeditions to Mars. The success of missions like Blue Ghost is expected to shape the trajectory of future lunar exploration and deep-space missions in the coming years.

New Study Reveals Recent Ice Gains in Antarctica, But Long-Term Melting Continues

Global warming and climate change have been subjects of major concern for a long time. One of the key indicators of this phenomenon is the melting of ice in the polar regions. Researchers from Tongji University in Shanghai have been using NASA satellite data to track changes in Antarctica’s ice sheet over more than two decades. Their newest study states that despite the increase in global temperature, Antarctica has gained ice in recent years. However, it cannot be considered as a miraculous reversal in global warming because over these two decades, the overall trend is substantial ice loss. Most of the gains have been caused by unusual increased precipitation over Antarctica.

About the New study

According to the new study , NASA’s Gravity Recovery And Climate Experiment (GRACE) and GRACE Follow-On satellites have been monitoring this ice sheet since 2002. The ice sheet covering Antarctica is the largest mass of ice on Earth

The satellite data revealed that the sheet experienced a sustained period of ice loss between 2002 and 2020. The ice loss accelerated in the latter half of that period, increasing from an average loss of about 81 billion tons (74 billion metric tons) per year between 2002 and 2010, to a loss of about 157 billion tons (142 billion metric tons) between 2011 and 2020, according to the study. However, the trend then shifted.

The ice sheet gained mass from 2021 to 2023 at an average rate of about 119 billion tons (108 metric tons) per year. Four glaciers in eastern Antarctica also flipped from accelerated ice loss to significant mass gain.

General Trend in global warming

Climate change doesn’t mean that everywhere on Earth will get hotter at the same rate, so a single region will never tell the whole story of our warming world.

Historically, temperatures over much of Antarctica have remained relatively stable, particularly compared to the Arctic. Antarctica’s sea ice has also been much more stable relative to the Arctic, but that’s been changing in recent years.

Astronomers Discover Exceptionally Symmetrical Supernova Remnant Teleios

A Supernova remnant (SNR) with exceptional circular symmetry has been spotted by an international team of researchers. Supernova remnants (SNRs) are the remains of a supernova explosion, seen as diffuse,expanding structures. Observations show that SNRs harbor ejected material expanding from the supernova explosion. They also contain other interstellar material that has been swept up by the passage of the shockwave from the exploded star. This rather unusual SNR is named “Teleios”, the Greek term of perfect. The newfound SNR, officially designated as G305.4–2.2 was identified in the radio-continuum images of the Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU).

Unusual structure and properties

According to the research paper describing the “Teleios”, it stands out for its unusual symmetrical structure. SNRs generally are unsymmetrical due to uneven distribution of the interstellar medium (ISM) they expand into. A few remnants like lSNR J0624–6948, SN1987A, or MC SNR J0509–6731 exhibit similar morphology

According to the paper, G305.4–2.2 or “Teleios” is located at a distance of 7,170 or 25,100 light years away, corresponding to a diameter of 45.6 or 156.5 light years, respectively. The study found some extended radio emission inside the southeastern edge of Teleios’s shell. This suggests that at least some parts of this region might be affected by the interaction of Teleios with local interstellar medium (ISM) structures. A steep spectral index of -0.6 suggests the remnant is either relatively young or very old and exhibits low surface brightness. These features make Teleios a compelling target for deeper investigation.

Possible Origins and Future Research

The study’s authors propose that Teleios likely originated from a Type Ia supernova, possibly formed below the Milky Way’s galactic plane. However, no direct evidence currently confirms this hypothesis. To uncover more about Teleios’s origin and evolution, the researchers recommend future high-resolution, multi-frequency observations.

These could reveal its expansion velocity and provide a clearer picture of its age and composition. Such efforts would not only enhance understanding of this unique remnant but also offer broader insights into the diversity and behaviour of supernova explosions in our galaxy.

NASA’s SWOT Satellite Reveals Big Impact of Small Ocean Currents and Waves on Ocean

Small-scale ocean features once overlooked are now seen as powerful forces shaping Earth’s climate and marine life. Developed in association with the French space agency CNES, the SWOT (Surface Water and Ocean Topography) satellite caught two-dimensional images of submesoscale waves and eddies about a mile across in a recent NASA-led study. Now clearly seen in before-unheard-of clarity, these currents are essential in moving carbon, nutrients, and heat across the ocean. The high-resolution data of the satellite provides the most comprehensive picture yet of how small-scale vertical currents affect the ecosystems and climatic systems of the world.

NASA SWOT Satellite Discovers Vertical Ocean Currents Driving Climate and Ecosystem Change

As per a recent report from NASA’s Jet Propulsion Laboratory, SWOT revealed how vertical ocean circulation, previously too fine for satellite observation but too broad for ship-based tools, drives exchanges between ocean depths and the atmosphere. “Vertical currents can bring heat from deep layers to the surface, warming the atmosphere,” notes oceanographer Matthew Archer in a statement. SWOT tracked a submesoscale eddy in the Pacific’s Kuroshio Current and measured vertical circulation of up to 14 metres per day, showing how such features help sustain surface ecosystems.

The satellite also observed an internal solitary wave in the Andaman Sea with twice the energy of a typical internal tide, underscoring its ability to estimate energy movement in global waters. Scientists use sea surface height data from SWOT to infer wave slope and fluid pressure, which reveals current speed and the volume of energy or material being transported. “Force is the fundamental quantity driving fluid motion,” explained coauthor Jinbo Wang of Texas A&M University in the blog.

Researchers emphasise SWOT’s role in reshaping ocean modelling. “Now models must adapt to these small-scale features,” denotes JPL’s Lee Fu in the official NASA blog, adding that SWOT data is already being integrated into NASA’s ECCO ocean model. Through continuous monitoring, SWOT is intended to help clarify among environmental changes, ocean-atmosphere interaction, and climate behaviour.

The SWOT mission is a joint project between NASA and CNES, with contributions from CSA and the UK Space Agency, and represents a new era in observing Earth. Its snapshots of the globe every 21 days offer a one-of-a-kind glimpse of how small, dynamic ocean systems help control life and climate on Earth.
