Earth has captured a new mini-moon –



Earth has a tiny new companion in its journey around the sun — at least for now.

The new “mini-moon” is an asteroid called 2020 CD3. It’s about 1.9 to 3.5 metres in diameter, roughly between the size of a cow and a hippopotamus.

It was confirmed to have been captured and “temporarily bound to Earth” by the International Astronomical Union’s Minor Planet Centre at the Smithsonian Astronomical Observatory on Tuesday. The organization is responsible for the designation of minor bodies in the solar system.

The asteroid was discovered by Kacper Wierzchos and Theodore Prune, astronomers with the Catalina Sky Survey, on Feb. 15, Wierzchos said in a tweet that described it as “big news.”

The Catalina Sky Survey is a NASA-funded project based at the University of Arizona that catalogues potentially hazardous asteroids.

“It’s a big deal as out of ~1 million known asteroids, this is just the second asteroid known to orbit Earth,” Wierzchos said.

The first was 2006 RH120, also found by the Catalina Sky Survey, which most recently orbited Earth between Sept. 2006 and June 2007. It has since resumed orbiting the sun.

The reason mini-moons orbit Earth for such a short time — compared to the moon, which has been orbiting Earth for more than four billion years — is that they’re pulled by the Earth’s, the moon’s and the sun’s gravity at the same time, producing irregular orbits.

At some point, the sun’s gravity will win, and the object will break free from its orbit around Earth.

However, so far, astronomers estimate that 2020 CD3 has already been orbiting the Earth for about three years.

Even though mini-moons are rarely discovered, a University of Hawaii study in 2011 calculated that there should be at least one asteroid with a diameter of at least one metre orbiting Earth at any given time. On average, such a mini-moon would orbit Earth for nine months, but some could orbit for decades, it estimated.

Boeing’s CST-100 Starliner spacecraft landed at the U.S. Army’s White Sands Missile Range in New Mexico at 5:49 p.m. Central Time. The safe return to Earth brings a close to the successful end-to-end uncrewed orbital flight test that was flown to demonstrate the quality and performance of the transportation system prior to crewed flights.

We have had an excellent flight test of a complex system that we expected to learn from along the way and we have,” said Mark Nappi, vice president and program manager, Boeing Commercial Crew Program. “Thank you to the NASA and Boeing teammates who have put so much of themselves into Starliner.”

The flight test completed today began May 19 with a launch from Florida’s Cape Canaveral Space Force Station atop a United Launch Alliance Atlas V rocket. Capabilities the Starliner demonstrated included:

  • End-to-end performance of the Atlas V rocket and Starliner spacecraft through launch, ascent, on-orbit, re-entry and landing;
  • Starliner’s autonomous software and the on-orbit operation of its avionics system, docking system, communications/telemetry systems, environmental control systems, solar arrays, electrical power systems, and propulsion systems;
  • Ability to hold docking attitude, receive commands from the space station crew, and command holds and retreats during final station approach;
  • Battery charging, hatch open and close, establishing joint ventilation with the station, file transfer and cargo transfer.

When Starliner completes its next flight, Boeing will have fulfilled NASA’s goal of having two commercial vehicles to transport astronauts safely, reliably and sustainably to the station from American soil.

With the completion of OFT-2, we will incorporate lessons learned and continue working to prepare for the crewed flight test and NASA certification,” Nappi added.

NASA skywatcher says a brand-new 'meteor storm' from a shattered comet might blaze across night skies next week – Yahoo Canada Finance

  • A meteor shower could light up skies over North America at the tail end of Memorial Day weekend.

  • The shower could become a rare “meteor storm,” with at least 1,000 meteors each hour, experts say.

  • The best time to catch the possible storm is around 1 a.m. ET on Tuesday, May 31.

North America might be treated to a starry spectacle late Monday night into Tuesday morning, as the Earth passes through the remnants of a defunct comet. Experts say the meteor shower, known as the Tau Herculids, has the potential to become a rare “meteor storm” — producing an onslaught of at least 1,000 shooting stars per hour.

Or, it could be a dud.

The comet is known as 73P/Schwassmann-Wachmann 3 (SW3 for short) and named after the two German astronomers — Arnold Schwassmann and Arno Arthur Wachmann — who discovered it in 1930. SW3 is breaking into dozens of pieces as it zips around the sun every 5.4 years, NASA said in a statement.

Like all meteor showers, experts say that when Earth passes through those comet crumbs, they’ll burn up in our atmosphere and create a scattering of shooting stars.

The Hubble Space Telescope provided astronomers with extraordinary views of Comet 73P/Schwassmann-Wachmann 3, a fragile comet that was rapidly disintegrating as it approached the Sun in 2006.The Hubble Space Telescope provided astronomers with extraordinary views of Comet 73P/Schwassmann-Wachmann 3, a fragile comet that was rapidly disintegrating as it approached the Sun in 2006.

The best meteor showers involve hundreds of meteors per hour — but most are in the single figures. Next week’s sky show could reach thousands of meteors per hour, making it a “meteor storm” as opposed to a shower, according to experts.

“This is going to be an all-or-nothing event,” Bill Cooke from NASA’s Meteoroid Environment Office, said in a statement, adding that visibility will depend on the speed of the comet. “If the debris from SW3 was traveling more than 220 miles per hour when it separated from the comet, we might see a nice meteor shower. If the debris had slower ejection speeds, then nothing will make it to Earth and there will be no meteors from this comet,” Cooke said.

The last “meteor storm” to grace the heavens was the Leonid meteor storm of 1966, which lasted several hours — meteors fell at rates as high as 40 per second.

“People who watched the 1966 Leonid shower said they felt they had to clutch the ground, so strong was the impression of Earth moving through space,” according to EarthSky.

The Tau Herculids meteor shower is named after the star Tau Herculis, because from Earth, the meteors appear as though they are radiating from Tau Herculis. Experts expect next week’s event to be much shorter than the hours-long Leonid shower.

Fortunately, the stellar light show will occur on a moonless night, making it easier to view. According to the American Meteor Society, the best window to see the cosmic display is from 12:45 to 1:17 a.m. ET on Tuesday, May, 31.

Though the light display should be visible from North and South America, stargazers in the Southwestern US and Mexico will have the best view, as that’s where the meteor shower will be highest in the night sky.

“We believe that this event has a chance of being something spectacular,” the society explained on its website. “When viewing events such as these, one should expect nothing extraordinary to happen, but certainly hope for the best!”

Curtiss-Wright Congratulates Nasa and Boeing on Successful Boeing Oft-2 Mission to the International Space Station – Space Ref



Press Release
From: Curtiss-Wright Corporation
Posted: Friday, May 27, 2022

Curtiss-Wright’s Defense Solutions division, a leading supplier of rugged flight test instrumentation solutions engineered to succeed, today congratulated NASA and Boeing on the successful Boeing Orbital Flight Test-2 mission to the International Space Station (ISS). Curtiss-Wright is proud to support this historic flight as a supplier of rugged data acquisition equipment used on board Boeing’s CST-100 Starliner spacecraft as part of the agency’s Commercial Crew Program. Curtiss-Wright supplies Boeing with the CST-100’s RAIU (Remote Analog Interface Unit) based on the Company’s Acra KAM-500 data handling avionics equipment. The RAIU is used to gather data on the status and health of critical spacecraft systems during all phases of the mission. 

The flight, NASA’s second uncrewed flight for Starliner, was launched to the ISS on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The OFT-2 mission demonstrates the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket from launch to docking to a return to Earth in the desert of the western United States.

“As a proud supplier to NASA’s Orbital Flight Test-2 mission to the International Space Station, we congratulate NASA and Boeing on the successful Boeing CST-100 Starliner spacecraft mission,” said Chris Wiltsey, Senior Vice President and General Manager, Defense Solutions division. “We are pleased that our proven and trusted space data acquisition technology are utilized to help capture the critical data required to support the development of this historic space vehicle.
