Webb mirror beauty
Wednesday, 12 May 2021 06:50The beauty shot video of the international James Webb Space Telescope (Webb) showing off the telescope's primary mirror.
The world’s most powerful space science telescope has opened its primary mirror for the last time on Earth.
As part of Webb’s final tests, the 6.5 meter (21 feet 4 inch) mirror was commanded to fully expand and lock itself into place, just like it would in space. The conclusion of this test represents the team’s final checkpoint in a long series of tests designed to ensure Webb’s 18 hexagonal mirrors are prepared for a long journey in space, and
Webb’s golden mirror wings open one last time on Earth
Wednesday, 12 May 2021 05:51The world’s most powerful space science telescope has opened its primary mirror for the last time on Earth.
As part of the international James Webb Space Telescope’s final tests, the 6.5 meter (21 feet 4 inch) mirror was commanded to fully expand and lock itself into place, just like it would in space. The conclusion of this test represents the team’s final checkpoint in a long series of tests designed to ensure Webb’s 18 hexagonal mirrors are prepared for a long journey in space, and a life of profound discovery. After this, all of Webb’s many movable parts will
How to keep spacesuit ‘underwear’ clean?
Wednesday, 12 May 2021 05:35Spacewalking is a major highlight of any astronaut’s career. But there is a downside: putting on your spacesuit means sharing some previously-worn underlayers. A new ESA study is looking into how best to keep these items clean and hygienic as humans venture on to the Moon and beyond.

Tuesday, 11 May 2021 22:06WASHINGTON — The U.S. Space Force on May 11 issued three requests for industry proposals on technologies that the military will need to reach space and to operate spacecraft in orbit.
The Space and Missile Systems Center’s Launch Enterprise is seeking proposals for next-generation rocket engine testing, launch vehicle upper stage enhancements, and capabilities to maneuver in space.
FAA rejects payload review for Momentus
Tuesday, 11 May 2021 21:36WASHINGTON — The Federal Aviation Administration has denied a payload review for in-space transportation company Momentus, meaning the company will miss its second opportunity to launch its first tugs.
In a May 11 filing with the Securities and Exchange Commission, Momentus said the FAA’s Office of Commercial Space Transportation notified the company May 10 that it had denied the company’s application for a payload review, part of the FAA’s launch licensing process.
Eutelsat financials show why it bought part of OneWeb
Tuesday, 11 May 2021 19:58TAMPA, Fla. — French satellite operator Eutelsat said revenue numbers will look much better than it expected come the end of June, despite reporting a decline in sales in its latest quarterly results.
Space telescope's golden mirror wings open one last time on Earth
Tuesday, 11 May 2021 17:59For the last time while it is on Earth, the world's largest and most powerful space science telescope opened its iconic primary mirror. This event marked a key milestone in preparing the observatory for launch later this year.
As part of the NASA's James Webb Space Telescope's final tests, the 6.5-meter (21-foot, 4-inch) mirror was commanded to fully expand and lock itself into place, just like it would in space.
Space Force renames Florida-based launch wing Space Launch Delta 45
Tuesday, 11 May 2021 15:12WASHINGTON — The U.S. Space Force has officially renamed the 45th Space Wing that oversees Florida’s launch ranges Space Launch Delta 45, the service announced May 11.
Plans to rename the former Air Force space launch wing were announced last month.
Senate Intelligence chairman wants further review of decision to relocate U.S. Space Command
Tuesday, 11 May 2021 13:00WASHINGTON — The chairman of the Senate Select Committee on Intelligence Sen. Mark Warner (D-Va.) is backing efforts by Sen. Michael Bennet (D-Colo.) to challenge the relocation of U.S. Space Command from Colorado to Alabama.
Understanding astronaut muscle wasting at the molecular level
Tuesday, 11 May 2021 11:33Researchers from the University of Tsukuba have sent mice into space to explore effects of spaceflight and reduced gravity on muscle atrophy, or wasting, at the molecular level.
Gravity is a constant force on Earth, which all living creatures have evolved to rely on and adapt to. Space exploration has brought about many scientific and technological advances, yet manned spaceflights come at a cost to astronauts, including reduced skeletal muscle mass and strength.
Conventional studies investigating the effects of reduced gravity on muscle mass and function have used a ground control group that is not directly comparable to the space experimental group. Researchers from the University of Tsukuba set out to explore the effects of gravity in mice subjected to the same housing conditions, including those experienced during launch and landing. "In humans, spaceflight causes muscle atrophy and can lead to serious medical problems after return to Earth," says senior author Professor Satoru Takahashi. "This study was designed based on the critical need to understand the molecular mechanisms through which muscle atrophy occurs in conditions of microgravity and artificial gravity.
US space probe Osiris-Rex heads home with asteroid dust
Tuesday, 11 May 2021 10:52The US space probe Osiris-Rex on Monday left the orbit of the asteroid Bennu, from which it collected dust samples last year, to begin its long journey back to Earth. The probe still has a vast distance to cover before it lands in the Utah desert on September 24, 2023. Osiris-Rex is "now moving away over 600 miles an hour from Bennu, on its way home," Dante Lauretta, head of the mission
Scientists catch exciting magnetic waves in action in the Sun's photosphere
Tuesday, 11 May 2021 10:41Researchers have confirmed the existence of magnetic plasma waves, known as Alfvén waves, in the Sun's photosphere. The study, published in Nature Astronomy, provides new insights into these fascinating waves that were first discovered by the Nobel Prize winning scientist Hannes Alfvén in 1947.
The vast potential of these waves resides in their ability to transport energy and information over very large distances due to their purely magnetic nature. The direct discovery of these waves in the solar photosphere, the lowest layer of the solar atmosphere, is the first step towards exploiting the properties of these magnetic waves.
The ability for Alfvén waves to carry energy is also of interest for solar and plasma-astrophysics as it could help explain the extreme heating of the solar atmosphere—a mystery that has been unsolved for over a century.
Elusive waves
Alfvén waves form when charged particles (ions) oscillate in response to interactions between magnetic fields and electrical currents.
Within the solar atmosphere bundles of magnetic fields, known as solar magnetic flux tubes, can form.
