SpaceX Starbase Flyover with Polaris Dawn Crew

SpaceX Starbase Flyover with Polaris Dawn Crew


Polaris Program will Undertake a Series of Pioneering SpaceX Dragon Missions, Demonstrating New Technologies and Culminating in the First Human Spaceflight on Starship

Led by tech entrepreneur and Inspiration4 commander Jared Isaacman, this program will advance deep space exploration while raising global awareness for St. Jude Children’s Research Hospital®. 

Los Angeles, California (February 14, 2022) – Today Jared Isaacman, founder and CEO of Shift4 (NYSE: FOUR), announced the Polaris Program, a first-of-its-kind effort to rapidly advance human spaceflight capabilities, while continuing to raise funds and awareness for important causes here on Earth. The program will consist of up to three human spaceflight missions that will demonstrate new technologies, conduct extensive research, and ultimately culminate in the first flight of SpaceX’s Starship with humans on board. 

The first mission, Polaris Dawn, is targeted for no earlier than the fourth quarter of this year and will be commanded by Isaacman, an accomplished pilot and astronaut who led Inspiration4, the world’s first all-civilian mission to orbit that helped raise over $240 million for St. Jude Children’s Research Hospital®.

“The Polaris Program is an important step in advancing human space exploration while helping to solve problems through the use of innovative technology here on Earth,” said Isaacman. “On Polaris Dawn, we endeavor to achieve the highest Earth orbit ever flown in addition to conducting the world’s first commercial spacewalk and testing of Starlink laser-based communication. Alongside these important objectives, we will be supporting scientific research to advance both human health interests on Earth and our understanding of human health during future long-duration spaceflights.” Building upon the Inspiration4 mission, Polaris Dawn will continue to raise funds and awareness for St. Jude Children’s Research Hospital®. 

THE POLARIS DAWN MISSION 

SpaceX’s Falcon 9 rocket will launch the Polaris Dawn mission from Launch Complex 39A at Kennedy Space Center in Florida. Dragon and the Polaris Dawn crew will spend up to five days in orbit, flying higher than any Dragon mission to date and endeavoring to reach the highest Earth orbit ever flown. 

While in orbit, SpaceX mission control will carefully monitor Dragon and the crew as they: – Attempt the first-ever commercial spacewalk with SpaceX-designed extravehicular activity (EVA) spacesuits, upgraded from the current intravehicular (IVA) suit. The development of this suit and the execution of the EVA will be important steps toward a scalable design for spacesuits on future long-duration missions. 

Become the first crew to test Starlink laser-based communications in space, providing valuable data for future space communications systems necessary for human spaceflight to the Moon, Mars, and beyond. 

Conduct scientific research designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflights. This includes, but is not limited to: 

Using ultrasound to monitor, detect, and quantify venous gas emboli (VGE), contributing to studies on human prevalence to decompression sickness; 

Gathering data on the radiation environment to better understand how space radiation affects human biological systems;

Providing biological samples towards multi-omics analyses for a long-term Biobank; and

Research related to Spaceflight Associated Neuro-Ocular Syndrome (SANS), which is a key risk to human health in long-duration spaceflight. 

SpaceX and Polaris Dawn will also collaborate with the Translational Research Institute for Space Health (TRISH), BioServe Space Technologies at the University of Colorado Boulder, Space Technologies Lab at Embry Riddle Aeronautical University, Weill Cornell Medicine, Johns Hopkins University Applied Physics Laboratory, the Pacific Northwest National Laboratory, and the U.S. Air Force Academy.

Ultralight Planet Found Next Door| European Southern Observatory (ESO)

Ultralight Planet Found Next Door | European Southern Observatory (ESO)

In this short video, we highlight the discovery of planet Proxima d around the star closest to the Sun.

A team of astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile have found evidence of another planet orbiting Proxima Centauri, the closest star to our Solar System. This candidate planet is the third detected in the system and the lightest yet discovered orbiting this star. At just a quarter of Earth’s mass, the planet is also one of the lightest exoplanets ever found.

“The discovery shows that our closest stellar neighbour seems to be packed with interesting new worlds, within reach of further study and future exploration,” explains João Faria, a researcher at the Instituto de Astrofísica e Ciências do Espaço, Portugal and lead author of the study published today in Astronomy & Astrophysics. Proxima Centauri is the closest star to the Sun, lying just over four light-years away.

The newly discovered planet, named Proxima d, orbits Proxima Centauri at a distance of about four million kilometres, less than a tenth of Mercury’s distance from the Sun. It orbits between the star and the habitable zone — the area around a star where liquid water can exist at the surface of a planet — and takes just five days to complete one orbit around Proxima Centauri.

The star is already known to host two other planets: Proxima b, a planet with a mass comparable to that of Earth that orbits the star every 11 days and is within the habitable zone, and candidate Proxima c, which is on a longer five-year orbit around the star.

Proxima b was discovered a few years ago using the HARPS instrument on ESO’s 3.6-metre telescope. The discovery was confirmed in 2020 when scientists observed the Proxima system with a new instrument on ESO’s VLT that had greater precision, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO). It was during these more recent VLT observations that astronomers spotted the first hints of a signal corresponding to an object with a five-day orbit. As the signal was so weak, the team had to conduct follow-up observations with ESPRESSO to confirm that it was due to a planet, and not simply a result of changes in the star itself.

“After obtaining new observations, we were able to confirm this signal as a new planet candidate,” Faria says. “I was excited by the challenge of detecting such a small signal and, by doing so, discovering an exoplanet so close to Earth.”  

At just a quarter of the mass of Earth, Proxima d is the lightest exoplanet ever measured using the radial velocity technique, surpassing a planet recently discovered in the L 98-59 planetary system. The technique works by picking up tiny wobbles in the motion of a star created by an orbiting planet’s gravitational pull. The effect of Proxima d’s gravity is so small that it only causes Proxima Centauri to move back and forth at around 40 centimetres per second (1.44 kilometres per hour).

“This achievement is extremely important,” says Pedro Figueira, ESPRESSO instrument scientist at ESO in Chile. “It shows that the radial velocity technique has the potential to unveil a population of light planets, like our own, that are expected to be the most abundant in our galaxy and that can potentially host life as we know it.”

The Heart Nebula | APoD

The Heart Nebula | APoD

Happy Valentine's Day!


What excites the Heart Nebula? First, the large emission nebula dubbed IC 1805 looks, in whole, like a human heart. Its shape is perhaps fitting for Valentine's Day. This heart glows brightly in red light emitted by its most prominent element: excited hydrogen. The red glow and the larger shape are all created by a small group of stars near the nebula's center. In the center of the Heart Nebula are young stars from the open star cluster Melotte 15 that are eroding away several picturesque dust pillars with their energetic light and winds. The open cluster of stars contains a few bright stars nearly 50 times the mass of our Sun, many dim stars only a fraction of the mass of our Sun, and an absent microquasar that was expelled millions of years ago. The Heart Nebula is located about 7,500 light years away toward the constellation of the mythological Queen of Aethiopia (Cassiopeia).

Tumultuous Galactic Trio | Hubble Space Telescope

Tumultuous Galactic Trio | Hubble Space Telescope


The mass of dust and bright swirls of stars in this image are the distant galaxy merger IC 2431, which lies 681 million light-years from Earth in the constellation Cancer. The NASA/ESA Hubble Space Telescope has captured what appears to be a triple galaxy merger in progress, as well as a tumultuous mixture of star formation and tidal distortions caused by the gravitational interactions of this galactic trio. The centre of this image is obscured by a thick cloud of dust—though light from a background galaxy can be seen piercing its outer extremities.  

This image is from a series of Hubble observations investigating weird and wonderful galaxies found by the Galaxy Zoo citizen science project. Using Hubble’s powerful Advanced Camera for Surveys (ACS), astronomers took a closer look at some of the more unusual galaxies that volunteers had identified. The original Galaxy Zoo project was the largest galaxy census ever carried out, and relied on crowdsourcing time from more than 100,000 volunteers to classify 900,000 unexamined galaxies. The project achieved what would have been years of work for a professional astronomer in only 175 days, and has led to a steady stream of similar astronomical citizen science projects. Later Galaxy Zoo projects have included the largest ever studies of galaxy mergers and tidal dwarf galaxies, as well as the discovery of entirely new types of compact star-forming galaxies.

"NASA’s first successful mission to another planet, Mariner 2 to Venus in 1962, marked the beginning of what former NASA Chief Scientist Jim Green describes in this volume as 'a spectacular era' of solar system exploration. In its first 50 years of planetary exploration, NASA sent spacecraft to fly by, orbit, land on, or rove on every planet in our solar system, as well as Earth’s Moon and several moons of other planets. Pluto, reclassified as a dwarf planet in 2006, was visited by the New Horizons spacecraft in 2015.

What began as an endeavor of two nations—the United States and the former Soviet Union—has become a multinational enterprise, with a growing number of space agencies worldwide building and launching planetary exploration missions—sometimes alone, sometimes together.

In this volume, a diverse array of scholars addresses the science, technology, policy, and politics of planetary exploration. This volume offers a collection of in-depth studies of important projects, decisions, and milestones of this era.

It is not possible to foresee what the next 50 years of NASA’s planetary exploration program will reveal. However, the 2020s are already looking promising. Planetary missions in recent years have focused more and more on exploring potentially habitable environments in our solar system and developing a more in-depth understanding of the evolution of planetary environments. Upcoming missions will continue to do so. In 2020, NASA launched its Mars 2020 rover, Perseverance, and in 2022 the European Space Agency will launch its Exomars rover. The Lucy and Psyche asteroid missions are set to launch in this decade, as are the Dragonfly mission to Titan and the Europa Clipper mission to the eponymous Jovian moon. Planetary defense is a new addition to NASA’s planetary portfolio, and the Agency’s Double Asteroid Redirection Test—its first planetary defense mission—is due to launch in 2021. NASA plans to develop a Near Earth Object Surveillance Mission this decade as well. It is safe to say that by 2062, our understanding of our solar system will be radically different than it is today. And we will look forward to it."

Aurora and Light Pillars over Norway | APoD

Aurora and Light Pillars over Norway | APoD


"Which half of this sky is your favorite? On the left, the night sky is lit up by particles expelled from the Sun that later collided with Earth's upper atmosphere—creating bright auroras. On the right, the night glows with ground lights reflected by millions of tiny ice crystals falling from the sky—creating light pillars. And in the center, the astrophotographer presents your choices." 

"The light pillars are vertical columns because the fluttering ice-crystals are mostly flat to the ground, and their colors are those of the ground lights. The auroras cover the sky and ground in the green hue of glowing oxygen, while their transparency is clear because you can see stars right through them. Distant stars dot the background, including bright stars from the iconic constellation of Orion. The featured image was captured in a single exposure two months ago near Kautokeino, Norway."

Aurora over Scotland

Aurora over Scotland

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth

Earth auroras have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

Photons Received: Webb Telescope Sees Its First Star—18 Times | NASA

Photons Received: Webb Telescope Sees Its First Star18 Times | NASA

The James Webb Space Telescope is nearing completion of the first phase of the months-long process of aligning the observatory’s primary mirror using the Near Infrared Camera (NIRCam) instrument.

The team's challenge was twofold: confirm that NIRCam was ready to collect light from celestial objects, and then identify starlight from the same star in each of the 18 primary mirror segments. The result is an image mosaic of 18 randomly organized dots of starlight, the product of Webb's unaligned mirror segments all reflecting light from the same star back at Webb's secondary mirror and into NIRCam's detectors.

What looks like a simple image of blurry starlight now becomes the foundation to align and focus the telescope in order for Webb to deliver unprecedented views of the universe this summer. Over the next month or so, the team will gradually adjust the mirror segments until the 18 images become a single star.

SpaceX Falcon 9 | Starlink Launch | NASA's Kennedy Space Center

SpaceX Falcon 9 | Starlink Launch | NASA's Kennedy Space Center

On Tuesday, January 18 at 9:02 p.m. EST, Falcon 9 launched 49 Starlink satellites to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida.

This was the tenth launch and landing of this Falcon 9 first stage booster, which has launched GPS III-3, Turksat 5A, Transporter-2, and now seven Starlink missions.

Starlink is a satellite Internet constellation operated by SpaceX providing satellite Internet access coverage to most of the Earth. The constellation has grown to over 1,700 satellites through 2021, and will eventually consist of many thousands of mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. While the technical possibility of satellite Internet service covers most of the global population, actual service can be delivered only in countries that have licensed SpaceX to provide service within a specific national jurisdiction. As of January 2022, the beta Internet service offering is available in 25 countries. (Source: Wikipedia)

NASA's Artemis I: The European Service Module | The Moon Journey

NASA's Artemis I: The European Service Module | The Moon Journey

Feb. 10, 2022: NASA's Orion spacecraft with the European Service Module will fly farther from Earth than any human-rated vehicle has ever flown before. This video gives an overview of the first mission—without astronauts—for Artemis, focusing on the European Space Agency’s European Service Module that powers the spacecraft.

The spacecraft will perform a flyby of the Moon, using lunar gravity to gain speed and propel itself 70,000 km beyond the Moon, almost half a million km from Earthfurther than any human has ever traveled.

On its return journey, Orion will perform another Moon flyby before heading back to Earth.

The total trip will take around 20 days, ending with a splashdown in the Pacific Ocean without the European Service Moduleit separates and burns up harmlessly in the atmosphere.

The second Artemis mission will have a similar flight plan but with astronauts. The third Artemis mission will see astronauts taken to the lunar surface.

The European Service Module is ESA’s contribution to NASA’s Orion spacecraft that will send astronauts to the Moon and beyond. It provides electricity, water, oxygen and nitrogen as well as keeping the spacecraft at the right temperature and on course.

The European Service Module has 33 thrusters, 11 km of electrical wiring, four propellant and two pressure tanks that all work together to supply propulsion and everything needed to keep astronauts alive far from Earththere is no room for error.

Artemis is the first step in the next era of human exploration. Together with commercial and international partners, NASA will establish a sustainable presence on the Moon to prepare for missions to Mars.
