SpaceX Falcon 9 Launch: GPS III Mission | Cape Canaveral Space Force Station

SpaceX Falcon 9 Launch: GPS III Mission | Cape Canaveral Space Force Station

A SpaceX Falcon 9 rocket on Jan. 18, 2023, lifted off at 7:24 a.m. Eastern from Space Launch Complex 40 at Cape Canaveral Space Force Station, Florida, carrying a U.S. Space Force GPS satellite. The Falcon 9 launched the Lockheed Martin-built GPS III SV-06—the 6th of the newest version of the satellite known as GPS III. The GPS constellation of 31 satellites operated by the U.S. Space Force provides positioning, navigation and timing signals to military and civilian users. GPS satellites operate in medium Earth orbit at an altitude of 12,550 miles. 

The launch of SV-06 was SpaceX’s fifth GPS mission, its second national security space launch of 2023 and Falcon 9’s 196th flight.

The first stage booster supporting this mission previously launched Crew-5 astronauts to the International Space Station. 

Approximately two and a half minutes after liftoff, the rocket’s first stage separated. Following separation, the first stage landed on the “A Shortfall of Gravitas” drone ship stationed in the Atlantic Ocean.

GPS III SV06 will augment the current GPS constellation that is comprised of 31 operational spacecraft operating in MEO at an altitude of approximately 20,200 km (12,550 miles) in six orbital planes. Each satellite circles the Earth twice per day. GPS is the premier space-based provider of positioning, navigation, and timing services for more than four billion users worldwide.

This latest generation of GPS satellite boasts a 15-year design life—25 percent longer than the previous generation of GPS satellites on orbit and brings new capabilities to users such as the new L1C civilian signal, which opens the window for future interoperability with international satellite navigation systems.

The payload for this mission is Global Positioning System III Space Vehicle 06 (GPS-III-SV06). It was built in Littleton, Colorado, by Lockheed Martin and it was placed into a medium Earth orbit (MEO) with an operational circular orbit at 20,180 km and an inclination of 55 degrees.

GPS-III-SV06 had a launch mass of 4.352 kg and is named after Amelia Earhart, the famous aviator who became the first woman to cross the Atlantic Ocean solo in 1932. Earhart disappeared during a flight around the world in 1937.

The mission marked the fifth GPS III satellite launch aboard a SpaceX Falcon 9 rocket, with one previously launched on a United Launch Alliance Delta IV Medium+ (4,2) rocket.

NASA's Space to Ground: First Timers | Week of Jan. 20, 2023

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. NASA astronaut Nicole Mann and Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata concluded their spacewalk on Jan. 20, 2023, at 3:35 p.m. EST after 7 hours and 21 minutes.

Mann and Wakata completed work left over from a previous spacewalk for a platform on which a set of International Space Station Roll-Out Solar Arrays (iROSAs) for the station’s 1B power channel will be installed later this year, as well as most of the work to install a similar mounting platform for a set of iROSAs for the 1A power channel. Due to time constraints, plans to bolt a final strut for the second platform were deferred until a future spacewalk. There is no impact to station operations.

The installation is part of a series of spacewalks to augment the International Space Station’s power channels with new iROSAs. Four iROSAs have been installed so far, and two more will be mounted to the platforms installed during this spacewalk in the future.

It was the 258th spacewalk in support of space station assembly, upgrades, and maintenance, the first spacewalk of 2023, and the first spacewalk for both astronauts.

Mann and Wakata are in the midst of a planned six-month science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.

Light Pollution: Stars Disappearing, Citizen Scientists Report | Globe at Night

Light Pollution: Stars Disappearing, Citizen Scientists Report | Globe at Night

The infographic above illustrates the impact of light pollution on our ability to see stars and other objects in the night sky.

A startling analysis from Globe at Night—a citizen science program run by the National Science Foundation’s NOIRLab—concludes that stars are disappearing from human sight at an astonishing rate. The study finds that, to human eyes, artificial lighting has dulled the night sky more rapidly than indicated by satellite measurements. The study published in the journal Science showcases the unique contributions that citizen scientists can make in essential fields of research.

From the glowing arc of the Milky Way to dozens of intricate constellations, the unaided human eye should be able to perceive several thousand stars on a clear, dark night. Unfortunately, growing light pollution has robbed about 30% of people around the globe and approximately 80% of people in the United States of the nightly view of their home galaxy. A new paper published in the journal Science concludes that the problem is getting rapidly worse.

New citizen-science-based research sheds alarming light on the problem of ‘skyglow’—the diffuse illumination of the night sky that is a form of light pollution. The data for this study came from crowd-sourced observations collected from around the world as part of Globe at Night, a program run by the NSF’s NOIRLab and developed by NOIRLab astronomer Connie Walker. The research reveals that skyglow is increasing more rapidly than shown in satellite measurements of Earth's surface brightness at night. 

“At this rate of change, a child born in a location where 250 stars were visible would be able to see only around 100 by the time they turned 18,” said Christopher Kyba, a researcher at the German Research Centre for Geosciences and lead author of the paper detailing these results.

Light pollution is a familiar problem that has many detrimental effects, not only on the practice of astronomy. It also has an impact on human health and wildlife, since it disrupts the cyclical transition from sunlight to starlight that biological systems have evolved alongside. Furthermore, the loss of visible stars is a poignant loss of human cultural heritage. Until relatively recently, humans throughout history had an impressive view of the starry night sky, and the effect of this nightly spectacle is evident in ancient cultures, from the myths it inspired to the structures that were built in alignment with celestial bodies.

Despite being a well-recognized issue, however, the changes in sky brightness over time are not well documented, particularly on a global scale.

Globe at Night has been gathering data on stellar visibility every year since 2006. Anyone can submit observations through the Globe at Night web application: https://www.globeatnight.org/webapp/ on a desktop or smartphone. After entering the relevant date, time and location, participants are shown a number of star maps. They then record which one best matches what they can see in the sky without any telescopes or other instruments.

Globe at Night: https://www.globeatnight.org

This gives an estimate of what is called the naked eye limiting magnitude, which is a measure of how bright an object must be in order to be seen. This can be used to estimate the brightness of skyglow, because as the sky brightens, the fainter objects disappear from sight.

The authors of the paper analyzed more than 50,000 observations submitted to Globe at Night between 2011 and 2022, ensuring consistency by omitting entries that were affected by factors including cloud cover and moonlight. They focused on data from Europe and North America, since these regions had a sufficient distribution of observations across the land area as well as throughout the decade studied. The paper notes that the sky is likely brightening more quickly in developing countries, where satellite observations indicate the prevalence of artificial lighting is growing at a higher rate.

After devising a new method to convert these observations into estimates of the change in skyglow, the authors found that the loss of visible stars reported by Globe at Night indicates an increase in sky brightness of 9.6% per year over the past decade. This is much greater than the roughly 2% per year global increase in surface brightness measured by satellites.

“This shows that existing satellites aren't sufficient to study how Earth's night is changing,” said Kyba. “We've developed a way to ‘translate’ Globe at Night observations of star visibility made at different locations from year to year into continent-wide trends of sky brightness change. That shows that Globe at Night is not just an interesting outreach activity, it is an essential measurement of one of Earth's environmental variables.”

Existing satellites are not well suited to measuring skyglow as it appears to humans, because there are no current instruments monitoring the whole Earth that can detect wavelengths shorter than 500 nanometers, which corresponds to the color cyan, or greenish blue. Shorter wavelengths, however, contribute disproportionately to skyglow, because they scatter more effectively in the atmosphere. White LEDs, now increasingly commonly used in high-efficiency outdoor lighting, have a peak in emission between 400 and 500 nanometers. 

“Since human eyes are more sensitive to these shorter wavelengths at nighttime, LED lights have a strong effect on our perception of sky brightness,” said Kyba. “This could be one of the reasons behind the discrepancy between satellite measurements and the sky conditions reported by Globe at Night participants.”

Beyond wavelength differences, space-based instruments do not measure light emitted horizontally very well, such as from illuminated signs or windows, but these sources are significant contributors to skyglow as seen from the ground. Crowd-sourced observations will therefore always be invaluable for investigating the direct human effects of sky brightness.

“The increase in skyglow over the past decade underscores the importance of redoubling our efforts and developing new strategies to protect dark skies,” said Walker. “The Globe at Night dataset is indispensable in our ongoing evaluation of changes in skyglow, and we encourage everyone who can to get involved to help protect the starry night sky.”

The image above, which is brimming with stars and dark dust clouds, is a small extract—a mere pinprick— of the full Dark Energy Camera Plane Survey (DECaPS2) of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects—arguably the largest such catalog so far. The data for this unprecedented survey were taken with the US Department of Energy-fabricated Dark Energy Camera at the National Science Foundation’s Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLab.

Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects—arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera, built by the US Department of Energy, at the National Science Foundation’s Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLab.

The Milky Way Galaxy contains hundreds of billions of stars, glimmering star-forming regions, and towering dark clouds of dust and gas. Imaging and cataloging these objects for study is a herculean task, but a newly released astronomical dataset known as the second data release of the Dark Energy Camera Plane Survey (DECaPS2) reveals a staggering number of these objects in unprecedented detail. The DECaPS2 survey, which took two years to complete and produced more than 10 terabytes of data from 21,400 individual exposures, identified approximately 3.32 billion objects—arguably the largest such catalog compiled to date. Astronomers and the public can explore the dataset here:

This unprecedented collection was captured by the Dark Energy Camera (DECam) instrument on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF's NOIRLab. CTIO is a constellation of international astronomical telescopes perched atop Cerro Tololo in Chile at an altitude of 2200 meters (7200 feet). CTIO’s lofty vantage point gives astronomers an unrivaled view of the southern celestial hemisphere, which allowed DECam to capture the southern Galactic plane in such detail.

DECaPS2 is a survey of the plane of the Milky Way as seen from the southern sky taken at optical and near-infrared wavelengths. The first trove of data from DECaPS was released in 2017, and with the addition of the new data release, the survey now covers 6.5% of the night sky and spans a staggering 130 degrees in length. While it might sound modest, this equates to 13,000 times the angular area of the full Moon. 

The DECaPS2 dataset is available to the entire scientific community and is hosted by NOIRLab’s Astro Data Lab, which is part of the Community Science and Data Center. Interactive access to the imaging with panning/zooming inside of a web-browser is available from the Legacy Survey Viewer, the World Wide Telescope and Aladin. 

Most of the stars and dust in the Milky Way are located in its disk—the bright band stretching across this image—in which the spiral arms lie. While this profusion of stars and dust makes for beautiful images, it also makes the Galactic plane challenging to observe. The dark tendrils of dust seen threading through this image absorb starlight and blot out fainter stars entirely, and the light from diffuse nebulae interferes with any attempts to measure the brightness of individual objects. Another challenge arises from the sheer number of stars, which can overlap in the image and make it difficult to disentangle individual stars from their neighbors. 

Despite the challenges, astronomers delved into the Galactic plane to gain a better understanding of our Milky Way. By observing at near-infrared wavelengths, they were able to peer past much of the light-absorbing dust. The researchers also used an innovative data-processing approach, which allowed them to better predict the background behind each star. This helped to mitigate the effects of nebulae and crowded star fields on such large astronomical images, ensuring that the final catalog of processed data is more accurate. 

“One of the main reasons for the success of DECaPS2 is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” said Andrew Saydjari, a graduate student at Harvard University, researcher at the Center for Astrophysics | Harvard & Smithsonian and lead author of the paper. “Doing so allowed us to produce the largest such catalog ever from a single camera, in terms of the number of objects observed.”

“When combined with images from Pan-STARRS 1, DECaPS2 completes a 360-degree panoramic view of the Milky Way's disk and additionally reaches much fainter stars,” said Edward Schlafly, a researcher at the AURA-managed Space Telescope Science Institute and a co-author of the paper describing DECaPS2 published in the Astrophysical Journal Supplement. “With this new survey, we can map the three-dimensional structure of the Milky Way's stars and dust in unprecedented detail.”

“Since my work on the Sloan Digital Sky Survey two decades ago, I have been looking for a way to make better measurements on top of complex backgrounds," said Douglas Finkbeiner, a professor at the Center for Astrophysics, co-author of the paper, and principal investigator behind the project. “This work has achieved that and more!"

“This is quite a technical feat. Imagine a group photo of over three billion people and every single individual is recognizable!” says Debra Fischer, division director of Astronomical Sciences at NSF. “Astronomers will be poring over this detailed portrait of more than three billion stars in the Milky Way for decades to come. This is a fantastic example of what partnerships across federal agencies can achieve.”

DECam was originally built to carry out the Dark Energy Survey, which was conducted by the Department of Energy and the US National Science Foundation between 2013 and 2019.
