An anti-satellite missile test Russia conducted on Monday generated a debris field in low-Earth orbit that endangered the International Space Station and will pose a hazard to space activities for years, U.S. officials said.
The seven-member space station crew – four U.S. astronauts, a German astronaut and two Russian cosmonauts – were directed to take shelter in their docked spaceship capsules for two hours after the test as a precaution to allow for a quick getaway had it been necessary, NASA said.
The research lab, orbiting about 250 miles (402 km) above Earth, continued to pass through or near the debris cluster every 90 minutes, but NASA specialists determined it was safe for the crew to return to the station’s interior after the third pass, the agency said.
The crew was also ordered to seal off hatches to several modules of the International Space Station (ISS) for the time being, according to NASA.
“NASA will continue monitoring the debris in the coming days and beyond to ensure the safety of our crew in orbit,” NASA chief Bill Nelson said in the statement.
Experts say the testing of weapons that shatter satellites in orbit pose a space hazard by creating clouds of fragments that can collide with other objects, setting off a chain reaction of projectiles through Earth orbit.
THOUSANDS OF FRAGMENTS
The Russian military and ministry of defense were not immediately available for comment. A message posted on Twitter by the Russian space agency Roscosmos downplayed the danger.
“The orbit of the object, which forced the crew today to move into spacecraft according to standard procedures, has moved away from the ISS orbit,” Roscosmos tweeted. “The station is in the green zone.”
The direct-ascent anti-satellite missile fired by Russia into one of its own satellites generated more than 1,500 pieces of “trackable orbital debris” and would likely spawn hundreds of thousands of smaller fragments, the U.S. Space Command said in a statement.
“Russia has demonstrated a deliberate disregard for the security, safety, stability and long-term sustainability of the space domain for all nations,” space command chief U.S. Army General James Dickinson said.
The debris from the missile test “will continue to pose a threat to activities in outer space for years to come, putting satellites and space missions at risk, as well as forcing more collision avoidance maneuvers,” he said.
U.S. Secretary of State Antony Blinken condemned the missile test as “reckless and irresponsible.” At the Pentagon, spokesman John Kirby said the test showed the need to firmly establish norms of behavior in space.
“It is unthinkable that Russia would endanger not only the American and international partner astronauts on the ISS, but also their own cosmonauts,” Nelson said. He said the cloud of debris also posed a threat to a separate Chinese space station under construction and the three-member crew of “taikonauts” aboard that outpost.
The incident came just four days after the latest group of four space station astronauts – Americans Raja Chair, Tom Marshburn and Kayla Barron of NASA and European Space Agency crewmate Matthias Maurer of Germany – arrived at the orbiting platform to begin a six-month science mission.
They were welcomed by three space station crew members already on board – U.S. astronaut Mark Vande Hei and Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov.
“Thanks for the crazy but well-coordinated day. We really appreciated all the situational awareness you gave us,” Vande Hei said in a Monday radio transmission to NASA posted online by Space.com. “It was certainly a great way to bond as a crew, starting off our very first workday in space.”
The space station, spanning the size of an American football field end to end, has been continuously occupied since November 2000, operated by an international partnership of five space agencies from 15 countries, including Russia’s Roscosmos.
Russia is not the first country to conduct anti-satellite tests in space. The United States performed the first in 1959, when satellites were rare and new.
In April Russia carried out another test of an anti-satellite missile as officials have said that space will increasingly become an important domain for warfare.
In 2019, India shot down one of its own satellites in low-Earth orbit with a ground-to-space missile.
These tests have raised questions about the long-term sustainability of space operations essential to a huge range of commercial activities, from telecommunications and weather forecasting to banking and GPS services.

'Use this technology to monitor the progression': How space tech can help the world fight the pandemic – USA TODAY
SpaceX and NASA Crew-3 mission finally launch into space after delays
After several delays, the SpaceX and NASA Crew-3 mission finally launched into space with four astronauts.
USA TODAY, Storyful
Michael Strahan, former football star and host of “Good Morning America,” will be taking off with a crew of five other passengers on Dec. 9, amidst a global pandemic and rising cases of the new omicron variant.
Strahan won’t be the first civilian in space. In September, the Inspiration4 launch sent four civilians (a physician’s assistant, an aerospace worker, a professor and a billionaire) into orbit. In October, William Shatner became the oldest person to go into space, at the age of 90.
Civilian spaceflight launches have had a shining spotlight in a time when COVID devastated regions all over the globe. Some, like Prince William, have even criticized the obsession on spaceflight, saying billionaires and companies should focus more on addressing issues closer to Earth.
But could technology developed for space help us battle the pandemic?
An article released in September in the peer-reviewed journal Nature Medicine investigated how space-based technologies could be used to help manage and prevent pandemics.
How much a seat into space costs: William Shatner went to space. Here’s how much it would cost you.
Telemedicine was ‘developed by space agencies’
When astronauts are in space, for example, their medical information is meticulously tracked, the paper says.
In fact, astronauts often run medical experiments in space to help researchers better understand how the human body reacts to the properties of space, according to Phil McAlister, director of commercial spaceflight at NASA.
For the SpaceX Inspiration4 launch, McAlister said, civilians conducted a series of experiments, such as drawing blood in space, and shared the data with researchers on Earth.
“Telemedicine was actually developed by space agencies as well in order to provide care, monitor the care of astronauts,” says Dr. Farhan Asrar, a medical doctor and global faculty member at the International Space University. Asrar was a contributor to the Nature Medicine article.
Similarly, Asrar points out, telemedicine can be used to monitor and assess COVID patients remotely without the risk of infecting healthcare workers.
Asrar says that wearable technology has already been used by Canadian astronauts to monitor several key parameters of health, such as blood pressure, temperature, breathing rate and heart rate, all of which were streamed hundreds of miles from Earth aboard the International Space Station.
These wearable devices can be used by healthcare workers to detect early on whether they are developing and spreading symptoms, the paper suggests.
Using satellite imagery to monitor progression
Satellite imagery could contribute to pandemic planning and the distribution of vaccines against COVID-19, according to the paper.
Satellites launched into space have already helped plot disease transmission during the Ebola outbreak, the paper points out. In the fight against polio, satellite images found marginalized and previously unknown villages in Nigeria, assisting with eradication efforts.
“There are several parameters which you can monitor using satellites,” Asrar says. “We can monitor temperatures that are ideal for these infectious conditions so that if an outbreak is occurring, you can use this technology to monitor the progression.”
Asrar cites using satellite monitoring on mosquito populations as a potential way to predict outbreaks of malaria.

Isolation and developing techniques to preserve mental health
One more thing we can learn from astronauts is the science of managing isolation, the paper says.
Astronauts often have to be in space for days or months on end, with little or no contact with their loved ones. In a similar sense, social distancing guidelines have prevented people from gathering and made those with limited technological resources even more isolated, the paper points out.
In another article published in Nature in May of 2020, astronauts shared ways that they dealt with isolation in space, including having a carefully managed daily routine and structuring work around an inspiring mission.
Both research papers suggest that by understanding how astronauts cope with isolation, we can develop better techniques for preserving our mental health during the pandemic.

NASA’s DART Kinetic Impactor Spacecraft Launches in World’s First Planetary Defense Test Mission – SciTechDaily
Lighting up the California coastline early in the morning of November 24, a SpaceX Falcon 9 rocket carried <span aria-describedby="tt" class="glossaryLink" data-cmtooltip="
“>NASA’s Double Asteroid Redirection Test (DART) spacecraft off the planet to begin its one-way trip to crash into an asteroid.
DART — a mission designed, developed, and managed by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Planetary Defense Coordination Office — is the world’s first full-scale mission to test technology for defending the planet against potential asteroid or comet hazards. The spacecraft launched Wednesday morning at 1:21 a.m. EST from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
As just one part of NASA’s larger planetary defense strategy, DART will send a spacecraft to impact a known asteroid that is not a threat to Earth, to slightly change its motion in a way that can be accurately measured via ground-based telescopic observations. DART will show that a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it. It’s a method called kinetic impact, and the test will provide important data to help humankind better prepare for an asteroid that might post an impact hazard to Earth, should one ever be discovered.
“The Double Asteroid Redirection Test represents the best of APL’s approach to space science and engineering: identify the challenge, devise an innovative and cost-effective technical solution to address it, and work relentlessly to solve it,” said APL Director Ralph Semmel. “We are honored that NASA has entrusted APL with this critical mission, where the fate of the world really could rest on our success.”
At 2:17 a.m. EST, DART separated from the second stage of its launch vehicle. Minutes later, mission operators at APL received the first spacecraft telemetry data and started the process of orienting the spacecraft to a safe position for deploying its solar arrays. Almost two hours later, the spacecraft successfully unfurled its two 28-foot-long roll-out solar arrays. They will power both the spacecraft and NASA’s Evolutionary Xenon Thruster – Commercial (NEXT-C) ion engine, one of several technologies being tested on DART for future application on space missions.
“The DART team overcame the technical, logistical and personal challenges of a global pandemic to deliver this spacecraft to the launch pad, and I’m confident that its next step — actually deflecting an asteroid — will be just as successful,” said Mike Ryschkewitsch, head of APL’s Space Exploration Sector. “It gives me a lot of assurance that if we ever have to embark on an urgent planetary defense mission, we have the people and the playbook to make it happen.”
DART’s one-way trip is to the Didymos asteroid system, which comprises a pair of asteroids — one small, the other large — that orbit a common center of gravity. DART’s target is the asteroid moonlet Dimorphos, which is approximately 530 feet (160 meters) in diameter and orbits Didymos, which is approximately 2,560 feet (780 meters) in diameter. Since Dimorphos orbits the larger asteroid Didymos at a much slower relative speed than the pair orbits the Sun, the slight orbit change resulting from DART’s kinetic impact within the binary system can be measured much more easily than a change in the orbit of a single asteroid around the Sun.
The spacecraft will intercept the Didymos system in late September of 2022, intentionally slamming into Dimorphos at roughly 4 miles per second (6 kilometers per second) so that the spacecraft alters the asteroid’s path around Didymos. Scientists estimate the kinetic impact will shorten Dimorphos’ orbit by several minutes, and they will precisely measure that change using telescopes on Earth. The results will be used to both validate and improve scientific computer models that are critical to predicting the effectiveness of kinetic impact as a reliable method for asteroid deflection.
“It is an indescribable feeling to see something you’ve been involved with since the ‘words on paper’ stage become real and launched into space,” said Andy Cheng, one of the DART investigation leads at APL and the individual who came up with the idea of DART. “This is just the end of the first act, and the DART investigation and engineering teams have much work to do over the next year preparing for the main event — DART’s kinetic impact on Dimorphos. But tonight we celebrate!”
DART’s single instrument, the camera DRACO (Didymos Reconnaissance and Asteroid Camera for Optical navigation), will turn on a week from now and provide the first images from the spacecraft. DART will continue to travel just outside of Earth’s orbit around the Sun for the next 10 months until Didymos and Dimorphos will be a relatively close 6.8 million miles (11 million kilometers) from Earth.
A sophisticated guidance, navigation, and control (GNC) system, working with algorithms developed at APL called SMART Nav (Small-body Maneuvering Autonomous Real Time Navigation) will enable the DART spacecraft to identify and distinguish between the two asteroids and then, working in concert with the other GNC elements, direct the spacecraft toward Dimorphos, all within roughly an hour of impact.
Provided by the Italian Space Agency, the Light Italian CubeSat for Imaging of Asteroids (LICIACube) will ride along with DART and be released prior to impact. LICIACube will then capture images of the DART impact, the resulting ejecta cloud and possibly a glimpse of the impact crater on the surface of Dimorphos. It will also look at the back side of Dimorphos, which DRACO will never have a chance to see, gathering further data to enhance the kinetic models.
Space can help to solve the biggest challenges facing our planet. Here’s how – Euronews
The views and opinions expressed in this article are those of the author.
In Earth’s more than four billion years of existence, it has had so many monumental moments.
The first human to discover the use of fire, the first to invent the wheel. The first human to walk on the Moon, the creation of the internet. So much evolution. Earth has witnessed the formation of life, the destruction of species, advancements in technology and society, and, ultimately, the regression of its own health.
We are at a historical cornerstone in time right now. As forests burn with fire and cities flood with water, unprecedented challenges are facing Europe and the world at large. Right now is the moment to contribute with bold, shared ambitions to solutions enabled by space.
Ambition: More important than ever
Ambition. It’s a word I use a lot. Ambition is what has driven humans to achieve the momentous, the impossible, the unimaginable.
It is what drove Europeans to explore and cross the Atlantic to new lands and later to send the first radio signals across the same body of water. It drove Europeans to discover the antibiotic penicillin and to save millions of lives with it thereafter.
To discover the theory of general relativity. To send the first space probe to perform a detailed study of a comet, dispatch a lander to its surface, and in a spectacular finale, land on the comet itself.
Ambition. Our planet’s youth is bursting with ambition (mixed with disappointment, anger, and a smudge of hope, admittedly and, well, understandably), as we saw recently in the streets of Glasgow and beyond during COP-26.
It’s been said that ‘ambition is the road to success. But persistence is the vehicle you arrive in’.
Space missions need the strength of a united Europe
So, we must move from ambition to persistence and action on what was laid out in Agenda 2025 (the strategy I developed to raise Europe’s game in space). A strategy that moves towards tangible, programmatic, and systematic commitments that create dialogue, inspiration, and change.
This is precisely what the Matosinhos Manifesto, the resolution adopted unanimously on 19 November 2021 at the European Space Agency’s (ESA) Intermediate Ministerial Meeting in Portugal, does.
It represents strength in numbers. The strength of a united Europe to deliver services to its citizens by accelerating space for the betterment and advancement of its people and of the planet overall.
A Europe that puts the user and citizen at the centre of its space activities.
Three initiatives to drive missions forward
The Manifesto is a commitment to focus on three initiatives called “Accelerators”, to speed up the use of space to solve today’s biggest challenges. To focus on space for a green future, to better understand the current state of Earth, to develop scenarios and solutions for sustainable life on this planet and to contribute effectively to achieving climate neutrality.
Then we must move from studying, observing, and understanding the planet towards action based on the deep knowledge that we gain. This is where the second Accelerator comes into play: The need to develop a rapid and resilient crisis response system to support stakeholders to decisively act on crises facing Europe.
And we cannot focus on the first two without ensuring their protection. Therein lies the third Accelerator: the protection of space assets to contribute to safeguarding and protecting our assets from space debris and space weather threats.
Beyond this, we also need our own ‘giant leap’ moment to inspire young Europeans to become more inquisitive about STEM topics so that we can continue to strengthen and enhance these fields for future generations.
New space economy
Inspirational missions will help drive innovation in the new space economy that is beginning to take shape. The Inspirators mission is to catapult Europe’s position as a global leader in space technology, innovation and deep-space scientific exploration.
To promote commercialisation, a modern, forward-looking European entrepreneurial landscape, multilateral cooperation, education, the development of human capital and STEM.
Think missions to icy moons, to unveil secrets about the origins of life or space exploration to take European astronauts beyond the International Space Station.
The passing of the Matosinhos Manifesto recently has created the necessary momentum to reach beyond our ambitions and jump-start into action.
The next steps and decisions will be formulated and taken at the European Space Summit and the ESA Council Meeting at ministerial level, both to be held in 2022.
