SpaceX's Dragon

Dragon successfully completed the orbital reboost of the International Space Station at approximately 12:50 p.m. ET (1750 GMT), Nov. 8. Read our full story.


SpaceX will boost the space station for the first time Friday (Nov. 8), as the company prepares to eventually kill the orbiting complex.


A Dragon cargo spacecraft docked to the International Space Station (ISS) will fire its engines for 12.5 minutes on Friday (Nov. 8), NASA officials said at a press conference Monday (Nov. 4). Other spacecraft have done this before, but it will be a first for a SpaceX capsule — and an important precursor to a bigger Dragon vehicle that will one day drive the ISS to its demise.     READ MORE...

A Laser Communications Link Billions of Kilometers Away

The recent success of NASA’s laser communication test represents a paradigm shift in space technology. Traditionally, space missions have relied on radio frequencies for communication. However, laser-based systems offer a data transmission capacity up to 100 times greater than conventional methods.


This advancement is not just about speed; it’s about expanding our capabilities in space exploration. With improved data transfer rates, future missions could:

• Send high-resolution images and videos back to Earth more quickly
• Enable real-time communication with spacecraft and rovers
• Facilitate more complex scientific experiments in deep space
• Support potential human missions to Mars and beyond

The implications of this breakthrough are far-reaching, potentially transforming our understanding of the cosmos. Just as the Hubble Space Telescope captured breathtaking views of distant galaxies, future space telescopes equipped with laser communication could transmit even more detailed observations, expanding our knowledge of the universe.        READ MORE...

Forging of Stars & Planets

New insights into the formation of gas streams that propel the growth of infant stars have been unveiled by astronomers with help from NASA’s James Webb Space Telescope, revealing deeper insights into how they feed on material from their surrounding disks.

The new findings are offering astronomers unprecedented new details about young stars and planets, and the processes that give rise to their formation and evolution over time.

The new research focused on investigations into the structure of gas flows in protoplanetary disks, which are the massive, dusty clouds of gas surrounding newly formed stars. Based on recent Webb telescope data, researchers involved were able to confirm the existence of a previously “hidden” mechanism that astronomers have long suspected to be behind what allows stars to gain mass as they grow.

Revealing a Magnetic Mystery
Detailed in a new paper in Nature Astronomy, the new research, led by scientists from the University of Arizona and supported by the Max Planck Institute for Astronomy, reveals that magnetic winds play a key role in transporting material that helps stars grow, along with shaping the mass present in their surrounding disk into a planetary system.     READ MORE...

NASA's InfraRed Delivery

NASA’s TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft — the PTD-3 (Pathfinder Technology Demonstrator-3) — have completed their technology demonstration. 

The TBIRD payload spent the past two years breaking world records for the fastest satellite downlink from space using laser communications.

NASA’s PTD series leverages a common commercial spacecraft to provide a robust platform for effective testing of technologies with minimal redesign in between launches. 

After launch in May 2022 on the SpaceX Transporter 5 mission, the PTD-3 spacecraft entered low-Earth orbit and shortly after TBIRD began sending laser communications signals to an optical ground station in Table Mountain, California.     READ MORE...

NASA Launces Time Machine

The James Webb Space Telescope, also commonly called Webb, is the most significant advancement in human endeavor toward unraveling the mystery of the cosmos. This infrared observatory started in space with the support of NASA, ESA, and CSA; it can give a new perception of the evolution of the cosmos in the tendency to provide a glimpse of the Big Bang and its effect.

Webb is more than just a telescope – it is humanity’s most potent eye in the sky – providing the ability to observe the universe billions of years back and, hopefully, unlock the key to the cosmos’ evolution and provide answers to some of the most fundamental questions asked by humanity.

A mirror like no other: how Webb’s unprecedented design changes our understanding of the cosmos
Webb’s instrument, called the Mid-Infrared Instrument or MIRI, is designed to collect energy even from behind dust clouds and reveal the objects behind them. It has a mirror that is almost three times the size of the first space telescope, the Hubble, and is made of 18 hexagonal segments, collecting much more light than the earlier telescope, hence capturing the faint lights from the young universe.               READ MORE...

The Milky Way is just a speck in a universe filled with an untold number of galaxies. But if we had to take an educated guess, how many galaxies are in the universe?


That sounds like a simple question, but it's anything but. The first problem is that even with our most powerful telescopes, we can see only a tiny fraction of the universe.


"The observable universe is only that part of the universe from which the light has had time to reach us," astrophysicist Kai Noeske, now outreach officer at the European Space Agency, told Live Science.

Wealthy Asteroid Now Visible

A NASA spacecraft is still on its way to explore an ultra-valuable, metal-rich asteroid. However, you don't have to wait for the space agency to beam back pictures of the so-called "golden asteroid" in a few years to see it. Per Astronomy Magazine, 

Asteroid 16 Psyche will reach opposition—opposite to the Sun in our sky—at 1 a.m. CT on Aug. 6. It will be located among the stars in northern Capricornus glowing at a magnitude of 9.6. You can find Psyche in the southwestern sky in the early morning hours leading up to dawn, but you'll need a telescope to do so.           READ MORE...

NASA: Past Life on Mars

• 
  In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface.
• Now, a new discovery by NASA’s Perseverance rover shows a trifecta of compelling evidence—including the presence of water, organic compounds, and a chemical energy source—all on one rock located in the Jezero Crater.
• Although this is the best clue yet that microbial life existed on Mars, there are still other explanations that could explain this geologic display without the existence of microbes.

“Is there life on Mars” is a question that has vexed astrobiologists and David Bowie alike. While the latter imagined some macabre collection of arachnids on the Red Planet, NASA scientists are fixated on finding evidence that microbial life once flourished on the fourth rock from the Sun. So fixated, in fact, that the space agency has spent more than $5 billion getting two immensely complicated robotic rovers—Curiosity and Perseverance—onto the Martian surface with this specific microbial mission in mind.     READ MORE...

Confirmed Cave on the MOON

CAPE CANAVERAL, Fla. (AP) — Scientists have confirmed a cave on the moon, not far from where Neil Armstrong and Buzz Aldrin landed 55 years ago, and suspect there are hundreds more that could house future astronauts.

An Italian-led team reported Monday that there’s evidence for a sizable cave accessible from the deepest known pit on the moon. It’s located at the Sea of Tranquility, just 250 miles (400 kilometers) from Apollo 11’s landing site.

The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube.

Researchers analyzed radar measurements by NASA’s Lunar Reconnaissance Orbiter, and compared the results with lava tubes on Earth. Their findings appeared in the journal Nature Astronomy.

The radar data reveals only the initial part of the underground cavity, according to the scientists. They estimate it’s at least 130 feet (40 meters) wide and tens of yards (meters) long, probably more.      READ MORE...

Einstein Ring Seen by James Webb Telescope

A beautiful, "bejeweled" halo of warped light generated by a monster black hole takes center stage in one of the latest James Webb Space Telescope (JWST) images. The luminous loop, which is strikingly similar to an "Einstein ring," is adorned by four bright spots — but not all of them are real.

The star-studded halo in the new image is made up of light from a quasar — a supermassive black hole at the heart of a young galaxy that shoots out powerful energy jets as it gobbles up enormous amounts of matter. This quasar, previously known to scientists, is named RX J1131-1231 and is located around 6 billion light-years from Earth in the constellation Crater, according to the European Space Agency (ESA).

X-Shaped Structures in Space

A NASA satellite has spotted unexpected X- and C-shaped structures in Earth’s ionosphere, the layer of electrified gas in the planet’s atmosphere that allows radio signals to travel over long distances.


The ionosphere is an electrified region of Earth's atmosphere that exists because radiation from the sun strikes the atmosphere. Its density increases during the day as its molecules become electrically charged. That's because sunlight causes electrons to break off of atoms and molecules, creating plasma that enables radio signals to travel over long distances. The ionosphere’s density then falls at night — and that's where GOLD comes in.


NASA's Global-scale Observations of the Limb and Disk (GOLD) mission is a geostationary satellite that has been measuring densities and temperatures in Earth's ionosphere since its launch in October 2018. From its geostationary orbit above the western hemisphere, GOLD was recently studying two dense crests of particles in the ionosphere, located north and south of the equator. As night falls, low-density bubbles appear within these crests that can interfere with radio and GPS signals. However, it's not just the wax and wane of sunshine that affects the ionosphere — the atmospheric layer is also sensitive to solar storms and huge volcanic eruptions, after which the crests can merge to form an X shape.               READ MORE...

Asteroid Larger than Giza Pyramid

A skyscraper-size asteroid discovered two weeks ago will zoom between Earth and the moon on Saturday (June 29). At its closest approach, the space rock will pass within roughly 184,000 miles (295,000 kilometers) of our planet — about three-quarters the average distance between Earth and the moon.


The asteroid, named 2024 MK, is estimated to measure about 480 feet (146 meters) across, which is greater than the height of a 40-story building or the Great Pyramid of Giza.


During its closest approach, it will be traveling at roughly 21,000 mph (34,000 km/h), according to NASA. Astronomers in South Africa discovered the asteroid on June 16.        READ MORE...

Pillars of Creation

In 1995, the Hubble Space Telescope released images of the Pillars of Creation — stunning effervescent clouds of interstellar dust and gas, the place where stars are born.


Now, combining data from Hubble and the James Webb Space Telescope, NASA has released a gorgeous 3D visualization of the cosmic structures in both visible and infrared light.


"By flying past and amongst the pillars, viewers experience their three-dimensional structure and see how they look different in the Hubble visible-light view versus the Webb infrared-light view," principal visualization scientist Frank Summers said in a statement.

"The contrast helps them understand why we have more than one space telescope to observe different aspects of the same object," he continue

The Pillars of Creation, which lie about 5,700 light-years from Earth, are composed of cool molecular hydrogen and dust. Due to strong winds and radiation from young nearby hot stars, the pillars are starting to get stripped of their contents. Long, finger-like structures can be seen emerging from the top of the pillars, which are larger than our own solar system.


Inside these structures, hydrogen and dust is gravitationally collapsing into new, infant stars. These new stars will add to the continued dispersion of materials within the pillars. The tallest of the pillars spans 3 light-years from top to bottom — three-quarters of the distance between the sun and our closest star.         READ MORE...

Space Glass

Thanks to human ingenuity and zero gravity, we reap important benefits from science in space. Consider smart phones with built-in navigation systems and cameras.


Such transformational technologies seem to blend into the rhythm of our everyday lives overnight. But they emerged from years of discoveries and developments of materials that can withstand harsh environments outside our atmosphere. 

They evolve from decades of laying foundations in basic science to understand how atoms behave in different materials under different conditions.     READ MORE...

NASA's Proposed Plasma Rocket

The future of space travel depends on our ability to reach celestial pit stops faster and more efficiently. As such, NASA is working with a technology development company on a new propulsion system that could drop off humans on Mars in a relatively speedy two months’ time rather than the current nine month journey required to reach the Red Planet.

NASA’s Innovative Advanced Concepts (NIAC) program recently selected six promising projects for additional funding and development, allowing them to graduate to the second stage of development. 

The new “science fiction-like concepts,” as described by John Nelson, NIAC program executive at NASA, include a lunar railway system and fluid-based telescopes, as well as a pulsed plasma rocket.

The potentially groundbreaking propulsion system is being developed by Arizona-based Howe Industries. To reach high velocities within a shorter period of time, the pulsed plasma rocket would use nuclear fission—the release of energy from atoms splitting apart—to generate packets of plasma for thrust.   READ MORE...

Alone in the Universe

Are we alone in the universe?

It's a question that's been posed again and again. Carl Sagan posed it in the 1970s as a NASA mission scientist as the agency prepared to send its twin Viking landers to Mars.

And nearly 50 years after the first of two landers touched down on Mars, we're no closer to an answer as to whether there's life — out there.

Scientists haven't stopped looking. In fact, they've expanded their gaze to places like Saturn's largest moon, Titan and Jupiter's moon Europa.

The search for life beyond planet earth continues to captivate. And NASA has upcoming missions to both moons. Could we be closer to answering that question Carl Sagan asked some 50 years ago?     READ MORE...

US Coast Sinking Fast

Parts of the East Coast of the United States are sinking so fast it could threaten infrastructure, farmland and wetlands, according to NASA.

Some areas have seen a drop of more than 2 millimeters per year from 2007 to 2020.

Satellite data shows the two biggest changes are from Savannah to Myrtle Beach and off the coasts of Maryland and Pennsylvania.

Charleston is one of the fastest-sinking cities. It is more than 2 inches lower than it was in 2007, and that’s a big deal for a city that’s just 10 feet above sea level.

Because of that, the city is considering building an 8-mile seawall.   READ MORE...

NASA Found a Super Earth

A NASA telescope orbiting our planet has spotted an intriguing super-Earth — a world some 30 to 70 percent bigger than Earth.

This rocky planet is in another solar system 137 light-years away, which in the vastness of space is considered relatively close (a light-year is nearly 6 trillion miles). The exoplanet, called TOI-715 b, is about 1.5 times the size of Earth. And, crucially, this world orbits inside the habitable, or "Goldilocks," zone.

"That’s the distance from the star that could give the planet the right temperature for liquid water to form on its surface," NASA explained on its website. "Several other factors would have to line up, of course, for surface water to be present, especially having a suitable atmosphere."

TOI-715 b orbits quite close to its star (each orbit lasts just 19 days) — but scientists don't think its a hellish, scorching world, like some other exoplanets. That's because its star is a "red dwarf," which is both cooler and smaller than our medium-sized star, the sun.   READ MORE...

Internet On Moon

NASA is indeed bringing a celestial internet of sorts to the moon, but it is not the same internet we know on Earth. The technology employs a “protocol suite” of new networking technologies for transmitting information between astronauts in space and those on Earth.

Additionally, Nokia announced plans to bring LTE/4G to the moon to support communication between the lunar lander and rover.  In March 2023, NASA took to Instagram to share the space agency’s plans to install an internet-like network in space that will connect astronauts with researchers on Earth.

First Wooden Satellite

NASA and the Japan Aerospace Exploration Agency (JAXA) are planning to launch the world's first wooden satellite into space in a bid to make spaceflight more sustainable.


LignoSat, a coffee mug-size satellite made from magnolia wood, is set to launch into Earth's orbit by summer 2024, according to the space agencies.

Wood doesn't burn or rot in the lifeless vacuum of space, but it will incinerate into a fine ash upon reentry into Earth's atmosphere — making it a surprisingly useful, biodegradable material for future satellites. After successfully testing their wood samples aboard the International Space Station (ISS) earlier this year, the scientists believe the test satellite is fit for launch.    READ MORE...
