Martian Volcanoes | United Arab Emirates Hope Mission

Martian Volcanoes | United Arab Emirates Hope Mission

Olympus Mons (Latin for Mount Olympus) is an enormous shield volcano on the planet Mars (located in the middle of this image, left of center). The volcano has a height of over 21.9 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA) on NASA's Mars Global Surveyor (MGS). Olympus Mons is about two and a half times Mount Everest's height above sea level. It is the largest and highest mountain and volcano of the Solar System and is associated with the Tharsis Montes, a large volcanic region on Mars.

Three other major Martian volcanoes visible in this image are Arsia Mons (in the south, lower right), Pavonis Mons (right of center) and Ascraeus Mons (in the north, upper right).

The Emirates Mars Mission is a United Arab Emirates Space Agency uncrewed space exploration mission to Mars. The Hope orbiter was launched on July 19, 2020, and went into orbit around Mars on February 9, 2021. The mission design, development, and operations are led by the Mohammed bin Rashid Space Centre (MBRSC). The spacecraft was assembled in the United States at the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics (LASP), with support from Arizona State University (ASU) and the University of California, Berkeley.

A Former NASA Astronaut’s View on What is Next in Space Exploration | PBS NewsHour

As the world of aerospace continues to expand to include private companies that are now able to send people into orbit, space tech can help life on Earth. The advancement of space and medical technology is something orthopedic surgeon, oncologist, chemical engineer, and astronaut Robert Satcher knows about first hand. “A lot of the imaging technology we use on cancer patients: MRI, CT Scans owe part of that technology to what was developed at NASA,” Satcher said during a conversation with PBS NewsHour’s Nicole Ellis.

Robert Lee "Bobby" Satcher Jr. (born September 22, 1965) is an American physician, chemical engineer, and former NASA astronaut. He participated in 2 spacewalks during STS-129 in 2009, accumulating 12hrs 19min of EVA time. Satcher holds two doctorates (Ph.D., M.D.) and has received numerous awards and honors as a surgeon and engineer. 

Satcher receive a Bachelor of Science degree as well as a doctorate in Chemical Engineering from the Massachusetts Institute of Technology. He then went on to study medicine at Harvard Medical School, and received his medical doctorate in 1994. Satcher did his internship and residency at the University of California, San Francisco from 1995–2000, and postdoctoral research fellowship at University of California, Berkeley in 1998, and an orthopedic oncology fellowship at the University of Florida from 2000–2001. (Source: Wikipedia)

Our Earth: February 2, 2022 | NOAA/NASA DSCOVR

This is an "EPIC" Earth image from the Deep Space Climate Observatory (DSCOVR) satellite! 

This color image of Earth was taken on February 2, 2022, by the Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope from one million miles away—beyond the Moon's orbit. Tropical Cyclone Batsirai can be seen in the Indian Ocean close to the island country of Madagascar located approximately 400 kilometers (250 miles) off the coast of East Africa across the Mozambique Channel.

The Deep Space Climate Observatory is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite at the Sun-Earth L1 Lagrange point. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on February 11, 2015, from Cape Canaveral. This is NOAA's first operational deep space satellite and became its primary system of warning Earth in the event of solar magnetic storms.

The Coalsack Nebula

 The Coalsack Nebula

Astrophotographer Alan Tough: "Inca astronomers referred to the Coalsack Nebula as 'Yutu', a partridge-like bird native to the Andes. The two bright stars in the accompanying image belong to the Southern Cross. They are (lower-right) Acrux (Alpha Crucis) and (top-right) Mimosa (Beta Crucis). There are also several open star clusters visible here, including the wonderful Jewel Box to the left of Mimosa."

"I captured this image remotely, using iTelescope T70 in the Rio Hurtado Valley, Chile (hence the reference to Yutu!). The total exposure time was 75 minutes through LRGB filters."

Release Date: February 4, 2022

The Coalsack Nebula (Southern Coalsack, or simply the Coalsack) is the most prominent dark nebula in the skies, with a designation TGU H1867, first referred to in Cataloging 1850, being easily visible to the naked eye as a dark patch obscuring a brief section of Milky Way stars as they cross their southernmost region of the sky, east of Acrux (Alpha Crucis) which is the bright, southern pointer star of the southern cross. It dominates and overspills the southeast corner of what is considered the extent of the constellation Crux at a little less than twice the distance of Acrux, 180 parsecs (590 light years) away from Earth.

Earth from Space: Batura Glacier, Pakistan | European Space Agency

Earth from Space: Batura Glacier, Pakistan | European Space Agency

In this week's edition of the Earth from Space program, the Copernicus Sentinel-2 mission takes us over Batura Glacier—one of the largest and longest glaciers in the world, outside of the polar regions.

Located in the upper Hunza Valley, in the Gilgit-Baltistan region of Pakistan, the Batura Glacier is  approximately 57 km long. It flows from west to east and feeds the Hunza River in north Pakistan, then joins the Gilgit and Naltar Rivers before it flows into the Indus River.

The lower portions of the Batura Glacier feature a grey sea of rocks and gravelly moraine (an accumulation of rocks and sediment carried down by the glacier often caused by avalanches). The glacier has a mean ice thickness of around 150 m, with the lower parts of the glacier holding most of its mass.

This video contains false-color composite images using the near-infrared channel of the Copernicus Sentinel-2 mission to highlight vegetation, which appears in red. Batura is bordered by several villages and pastures with herds of sheep, goats and cows where roses and juniper trees are quite common. 

Batura Glacier is located just north of the Batura Muztagh, a sub-range of the Karakoram mountain range, which includes the massifs of the Batura Sar, the 25th highest mountain on Earth standing at 7795 m, and Passu Sar at 7478 m.

Glacier shrinkage is a prominent sign of ongoing climate change. However, unlike many glaciers around the world, the glaciers residing in the mountain ranges in Karakoram are not responding to global warming. Their retreating is less than the global average, and in some cases, are either stable or growing. This anomalous behavior of the region’s glaciers has been coined the ‘Karakoram Anomaly’.

Scientists typically measure the motions of glaciers with ground-based measurements. Because of the rugged terrain and challenges involved in field studies, long-term ground observational data on Karakoram is sparse. Satellites can help monitor changes in glacier mass, extents, trace area and length of glacier changes through time and derive surface velocity.

We are Europe's gateway to space. Our mission is to shape the development of Europe's space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

Rigel and the Witch Head Nebula | APoD

 Rigel and the Witch Head Nebula | APoD

By starlight this eerie visage shines in the dark, a crooked profile evoking its popular name, the Witch Head Nebula. In fact, this entrancing telescopic portrait gives the impression that the witch has fixed her gaze on Orion's bright supergiant star Rigel. More formally known as IC 2118, the Witch Head Nebula spans about 50 light-years and is composed of interstellar dust grains reflecting Rigel's starlight. The blue color of the Witch Head Nebula and of the dust surrounding Rigel is caused not only by Rigel's intense blue starlight but because the dust grains scatter blue light more efficiently than red. The same physical process causes Earth's daytime sky to appear blue, although the scatterers in Earth's atmosphere are molecules of nitrogen and oxygen. Rigel, the Witch Head Nebula, and gas and dust that surrounds them lie about 800 light-years away.

The Bahamas | International Space Station

The Bahamas | International Space Station

The island nation of the Bahamas is pictured from the International Space Station as it orbited 263 miles above the Atlantic Ocean. Astronauts of Expedition 66 captured this image. 

The Bahamas, officially the Commonwealth of the Bahamas, is an island country of the Lucayan Archipelago consisting of more than 700 islands, cays, and islets in the Atlantic Ocean; north of Cuba and Hispaniola (Haiti and the Dominican Republic); northwest of the Turks and Caicos Islands; southeast of the U.S. state of Florida and east of the Florida Keys. Its capital is Nassau on the island of New Providence. (Source: Wikipedia)

"The overview effect is a cognitive shift in awareness reported by some astronauts during spaceflight, often while viewing the Earth from outer space. It is the experience of seeing first-hand the reality of the Earth in space, which is immediately understood to be a tiny, fragile ball of life, 'hanging in the void', shielded and nourished by a paper-thin atmosphere. The effect may also invoke a sense of transcendence and connection with humanity as a whole, from which national borders appear petty." The term and concept were coined in 1987 by American author, Frank White, who explored the theme in his book The Overview Effect — Space Exploration and Human Evolution."

Hubble Gazes Sidelong at Barred Spiral Galaxy NGC 3568 | NASA/ESA

Hubble Gazes Sidelong at Barred Spiral Galaxy NGC 3568 

In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth—a sudden flare of light caused by the titanic explosion accompanying the death of a massive star. Whilst most astronomical discoveries are the work of teams of professional astronomers, this supernova was discovered by amateur astronomers from the Backyard Observatory Supernova Search in New Zealand. Dedicated amateur astronomers often make intriguing discoveries—particularly of fleeting astronomical phenomena such as supernovae. 

This Hubble observation comes from a hoard of data built up to pave the way for future science with the upcoming NASA/ESA/CSA James Webb Space Telescope. By combining ground-based observations with data from Hubble’s Advanced Camera for Surveys and Wide Field Camera 3, astronomers have built a treasure trove of data on the connections between young stars and the clouds of cold gas in which they form. One of Webb’s key science goals is to explore the life cycle of stars—particularly how and where stars are born. Since Webb observes at infrared wavelengths, it will be able to peer through the clouds of gas and dust in stellar nurseries and observe the fledgling stars within. Webb’s superb sensitivity will even allow astronomers to directly investigate faint protostellar cores—the earliest stages of star birth.

China’s Mars Mission: Tianwen-1 Orbiter Video Captures Ice Caps on Red Planet

China’s Mars Mission: Tianwen-1 Orbiter Video Captures Ice Caps on Red Planet

- China's space agency publishes videos of its spacecraft against backdrop of polar caps made from a mixture of frozen carbon dioxide and water

- By Monday, China's Zhu Rong rover had driven more than 1.5km (0.9 miles) on the planet’s surface

Jan. 31, 2022: China has published videos showing its Mars orbiter Tianwen-1 circling above the northern ice caps of the red planet taken using its “selfie stick” on Monday, the eve of Lunar New Year.

In a pink-tinted video, the spacecraft can be seen flying against a landscape sprinkled with frost patches, which the China National Space Administration (CNSA) identified as ice caps. Unlike the ice on the Earth’s polar regions, Martian ice is a mixture of frozen carbon dioxide and water.

The video also shows a moving shadow cast by the sun as the solar wings of the orbiter rotate.

The orbiter is equipped with an extendable arm to monitor the key components on its surface, according to the CNSA, which said its engine, propellant tank and attitude control engine were in sound condition.

The “selfie stick” is made of a shape memory material that unfurls straight to 1.6 metres (5.2 feet) long when it reaches a certain temperature after entering Mars’ orbit. The arm, which has a camera attached at the end, was folded before launch.

The Tianwen mission–those name translates to “heavenly questions”–is a milestone for China’s ambitious space programme. It was launched on July 23, 2020, and went into orbit around Mars seven months later. In May last year Zhu Rong, named after the Chinese god of fire, landed on the planet.

The space agency said both the Tiawen-1 orbiter and Zhu Rong rover were in “good condition”.

The rover had driven more than 1.5km (0.9 miles) on the Mars surface in 255 Martian days by Monday. A Martian day is about 40 minutes longer than a day on Earth.

The feat means China is only the second country after the United States to successfully land an operating spacecraft on Mars.

Its mission is to explore the surface and geology of the planet as well as its magnetic field, soil composition and atmosphere.

Zhang Rongqiao, chief designer of the Tianwen-1 mission, said China was also working on another mission–likely to be known as Tianwen-2 -to collect rock samples from the red planet and return them to Earth in 2030.

Hubble Revisits a Galactic Oddball | NASA/ESA

Hubble Revisits a Galactic Oddball | NASA/ESA

The dwarf galaxy NGC 1705 is featured in this image from the NASA/ESA Hubble Space Telescope. This diminutive galaxy lies in the southern constellation Pictor, and is approximately 17 million light-years from Earth. NGC 1705 is a cosmic oddball—it is small, irregularly shaped, and has recently undergone a spate of star formation known as a starburst. 

Despite these eccentricities, NGC 1705 and other dwarf irregular galaxies like it can provide valuable insights into the overall evolution of galaxies. Dwarf irregular galaxies tend to contain few elements other than hydrogen or helium, and are considered to be similar to the earliest galaxies that populated the Universe.

The data shown in this image come from a series of observations designed to unveil the interplay between stars, star clusters, and ionised gas in nearby star-forming galaxies. By observing a specific wavelength of light known as H-alpha with Hubble’s Wide Field Camera 3, astronomers aimed to discover thousands of emission nebulae — regions created when hot, young stars bathe the clouds of gas surrounding them in ultraviolet light, causing them to glow.

This is not the first time that NGC 1705 has been imaged by Hubble—astronomers peered into the heart of the galaxy in 1999 using Hubble’s workhorse camera at the time, the Wide Field Planetary Camera 2. This instrument was replaced with the Wide Field Camera 3 during the fifth and final Space Shuttle mission to Hubble in 2009, and the newer instrument has provided a richer and far more detailed portrait of NGC 1705 than the 1999 observation.
