For the very first time, a Centaur comet has been caught on camera amidst Jupiter’s ancient asteroids called Trojans using the National Aeronautics and Space Administration’s (<a href="https://www.nasa.gov/feature/goddard/2021/comet-makes-a-pit-stop-near-jupiters-asteroids">NASA</a>) legendary Hubble Telescope. <div type="javascript" title="Custom" contenttype="Video"><cdata><![CDATA[]]></cdata></div> Centaurs are small icy rocks that orbit the Sun between Jupiter and <keyword id="175328" type="PERSON" weightage="20" keywordseo="Neptune">Neptune</keyword>. Every once in a while, as they get closer to the Sun, these unstable balls of ice transform into comets upon being heated up. Trojans, on the other hand, are asteroids that only orbit Jupiter. There are over a million of them larger than 1 kilometer in diameter — that’s almost the same number of asteroids in the asteroid belt that divides the solar system’s inner four planets from the outer four. "The cool thing is that you are actually catching Jupiter flinging this object around and changing its orbital behavior and bringing it into the inner system," said team member Carey Lisse of the Johns Hopkins University Applied Physics Laboratory (APL) in a <a href="https://www.nasa.gov/feature/goddard/2021/comet-makes-a-pit-stop-near-jupiters-asteroids">statement.</a> The solar system is made up of two parts, the inner system and the outer system, divided by the asteroid belt. The inner system consists of Mercury, Venus, Earth and Mars while the outer system is made up of Jupiter, Saturn, Uranus and Neptune. <div type="image" title="planets_edited" msid="81227807" hostid="261" caption="&amp;lt;p&amp;gt;The asteroid belt lies dividing the inner and outer solar system lies between Mars and Jupiter&amp;lt;/p&amp;gt;"></div> How did this happen? Honestly, even NASA does not know. Scientists who made the discovery speculate that the comet had to have entered Jupiter’s orbit at just the right trajectory to not burn up, and not just fly by either. "Jupiter controls what is going on with comets once they get into the inner system by altering their orbits," explained Lisse. One possible explanation is that the Centaur, dubbed P/2019 LD2, is likely the latest member of the ‘bucket brigade’. These are comets that get kicked out of the <keyword id="166066" type="PERSON" weightage="20" keywordseo="Kuiper-belt">Kuiper belt</keyword> and into the orbits of large planets due to interactions with another Kuiper belt object before getting caught in a game of celestial pinball. <div type="image" title="kuiper belt." msid="81227818" hostid="261" caption="&amp;lt;p&amp;gt;The Kuiper Belt lies along the outer edges of the solar system&amp;lt;/p&amp;gt;"></div> The Kuiper belt is the asteroid belt’s outer solar system cousin. The haven of icy, leftover debris from our planet’s construction 4.6 billion years ago is located beyond even Neptune’s orbit. It contains millions of objects. Every once in a while, these objects have near misses or collisions that drastically alter their orbits from the Kuiper belt inward into the giant planet region. And, P/2019 LD2, is likely one of the many icy relics on a bumpy towards the Sun. According to the researchers at NASA, members of the bucket brigade can spend nearly five million years sucked into the gravity of a large planet before crossing over into the inner solar system. On the other hand, it i also possible that the Centaur will never make the crossing. "Short-period comets like LD2 meet their fate by being thrown into the Sun and totally disintegrating, hitting a planet, or venturing too close to Jupiter once again and getting thrown out of the solar system, which is the usual fate," explained Lisse.

An entire population was discovered between Jupiter and Neptune. The Centaur family of asteroids roam the space between the two gas giants but even computer models can’t predict where they’ll be headed next. <div type="image" title="centaur3_edited" msid="75351707" hostid="261" caption="&amp;lt;p&amp;gt;The Centaurs in the study have so far not been imaged directly. Their sizes range from 10km to 300km, and small Centaurs may look like the 53km asteroid Mathilde imaged by NASA’s NEAR Shoemaker mission in 1997&amp;lt;/p&amp;gt;"></div> “The discovery of a whole population of asteroids of interstellar origin is an important step in understanding the physical and chemical similarities and differences between solar system-born and interstellar asteroids,” said <a href="https://ras.ac.uk/news-and-press/research-highlights/interstellar-asteroids-found-hiding-plain-sight">Maria Helena Morais</a>, one of the authors of the discovery published in the <a href="https://doi.org/10.1093/mnras/staa712">Monthly Notices of the Royal Astronomical Society</a>. The general consensus in the scientific community is that interstellar asteroids are rare and visit the neck of the solar system every couple of years as they pass through. Other than that, we have the asteroid belt, which stretches from Mars to Jupiter. This also means that Oumuamua wasn’t the first interstellar visit and neither was Borisov. The <keyword id="9113018" type="UNKNOWN" weightage="20" keywordseo="centaur-asteroids">Centaur asteroids</keyword> have been around since the birth of our solar system — even though they themselves were born in other star systems. The origin story of Centaur asteroids These 19 new asteroids from the Centaur family could have originated outside the solar system, according to calculations. The researchers claim that there’s no other plausible explanation for their orbits and characteristics. The simulations show that these Centaurs orbit the Sun on a plane that was perpendicular to planetary motion at that time. They also imply that the asteroids were located far from the disc that gave rise to our own solar system’s asteroids. <div type="image" title="centaur_edited" msid="75351746" hostid="261" caption="&amp;lt;p&amp;gt;Illustration of the orbit of a Centaur asteroid 4.5 billion years ago, relative to the protoplanetary disc. The asteroid orbits around the sun far from the disc in a plane perpendicular to it.&amp;lt;/p&amp;gt;"></div> “The close proximity of the stars meant that they felt each others’ gravity much more strongly in those early days than they do today. This enabled asteroids to be pulled from one star system to another,” explained Fathi Namouni, lead author of the study. When our own solar system was born, 4.5 billion years ago, the Centaurs got caught in its gravity and have been orbiting our Sun in incognito mode ever since. On the hunt for other interstellar asteroids that may have been hiding in plain sight The ability to differentiate between interstellar asteroids and native asteroids has eluded astronomers for a long time. “This population will give us clues about the Sun’s early birth cluster, how interstellar asteroid capture occurred, and the role that interstellar matter had in chemically enriching the Solar System and shaping its evolution,” said Namouni. The scientists now plan to continue this work by looking for specific events when common capture of several extrasolar bodies occurred.

The launch of Boeing's Starliner spacecraft, scheduled to carry <keyword id="19939779" type="General" weightage="20" keywordseo="NASA-astronauts" source="keywords">NASA astronauts</keyword> <keyword id="21544825" type="General" weightage="20" keywordseo="Sunita-Williams" source="keywords">Sunita Williams</keyword> and Barry Wilmore to the International Space Station (ISS) was on Monday (local time) postponed after a valve glitch in the upper stage of the rocket set to propel it to space. Rocket company United Launch Alliance's Tom Heter III the director overseeing the launch announced the decision to delay the launch about two hours before the expected lift off from the Cape Canaveral Space Force Station in Florida, United States. NASA announced on social media platform X that the problem was identified with an oxygen valve on part of ULA's Atlas 5 rocket and that the space agency, Boeing and ULA have "scrubbed the launch opportunity on May 6 for the agency's Boeing Crew Flight Test to the International Space Station due to a faulty oxygen relief valve observation on the Atlas V rocket Centaur second stage. The crew and rocket remain safe and more information will be forthcoming." It said that NASA astronauts Wilmore and Williams exited the Starliner spacecraft at Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida and will return to astronaut crew quarters. This would have marked the first human crewed flight for Starliner with Indian origin Sunita "Suni" Williams piloting the craft with fellow NASA pilot Barry "Butch" Wilmore. Boing had designed Starliner to rival the Dragon capsule of Elon Musk's SpaceX which carried out its crewed flight test in May 2020. SpaceX has handled most of NASA's crew transportation needs since then. However, just two hours before the scheduled launch, a valve glitch in the rocket's upper stage forced mission managers to call off the mission. It was a frustrating setback for Wilmore and Williams, both seasoned astronauts ventured to space on two previous journeys aboard NASA space shuttle and Russian Soyuz missions and had impressive backgrounds in naval aviation. The disappointment was tangible as they unstrapped from their seats, their hopes of soaring into space momentarily grounded, CBS News reported. Incidentally Sunita Williams has named the spacecraft "Calypso" for her love of the ocean and in reference to the ship of famed explorer <keyword id="21556039" type="General" weightage="20" keywordseo="jacques-cousteau" source="keywords">Jacques Cousteau</keyword>, who sailed across the world on his own ship named bearing the same name. Despite the setback, the seasoned duo maintained their composure, knowing that space travel demands patience and resilience. Clad in their distinctive Boeing pressure suits, Wilmore and Williams awaited news of the next launch window, ready to embark on their celestial journey at the earliest opportunity, as reported by CBS News. The Atlas 5 rocket, renowned for its reliability, stood ready for its milestone 100th flight - to launch Boeing's Crew Space Transportation (CST)-100 Starliner spacecraft. The plan was that following separation from Atlas 5, Starliner engines will burn taking it the rest of the way to orbit and on to the International Space Station, according to ULA. The Atlas 5 had successfully launching scientific spacecraft to Mars on five different occasions, plus research investigations to the Sun, the Moon, Jupiter, the Asteroid Bennu and Pluto The Atlas 5 consists of two major components: a booster and Centaur, its so-called upper stage. Starliner sits on top of Centaur, which in turn rests on the booster. The booster powers everything off the launchpad. During the flight, Centaur is designed to separate from the booster, propelling Starliner into a proper orbit. Then, Starliner separates from Centaur and flies on its own. It has delivered US national security assets into space, launched weather observatories that all Americans depend upon and deployed commercial satellites to connect the world. Williams, selected as an astronaut by NASA in June 1998, has spent a total of 322 days in space on two missions and accumulated 50 hours and 40 minutes of cumulative EVA time on seven spacewalks. Williams worked with Roscosmos on its contribution to the space station and with the first Expedition crew. Meanwhile, 61-year-old, Wilmore has logged 178 days in space and has 25 hours and 36 minutes of time on four spacewalks. NASA has been waiting half a decade for Starliner to begin flying crew, and the development of Starliner was beset by years of delays, setbacks and blunders. More broadly, Boeing as a company has suffered years of scandals in its aircraft division that have tarnished the legacy aerospace giant's brand, CNN reported. If successful, the Crew Test Flight could queue up Boeing to begin flying routine trips to the space station on NASA's behalf. Boeing has already planned six manned missions for the platform over the next six years, the projected end of the ISS' operating lifespan. NASA plans to use both SpaceX's Dragon and Boeing's Starliner to send up astronauts at least every six months from US soil. Both Boeing and SpaceX were given the responsibility in 2014 by NASA to send commercial crew missions to the ISS. Boeing received over USD 4 billion in US federal funds to develop the Starliner, while SpaceX received about USD 2.6 billion.

After months of head-scratching, scientists finally identified this visitor from beyond.It's not an asteroid. It's not a comet. It's not an alien spaceship. On Wednesday, NASA confirmed that the object, formerly known as 2020 SO, is the booster of a Centaur rocket that launched in 1966.<div type="image" title="centaur rocket second stage" height="1536" width="2048" msid="79538692" hostid="261"></div>The rocket carried the Surveyor 2 mission, which was set to land on the moon, but went into a death spiral when one of its thrusters failed to fire with the others. Surveyor 2 crashed into the lunar surface, but the rocket booster had separated from the spacecraft shortly after pushing it towards its lunar destination. The booster then drifted, unseen, into the abyss of space.Now Earth's gravity has briefly captured the rocket booster once again, like a tiny moon orbiting our planet. It's set to loop Earth twice before escaping the planet's pull in March 2021. Then it will continue on a new orbit around the sun.<div type="image" title="2020 so rocket booster orbit" height="670" width="1168" msid="79538693" hostid="261"></div>Its Tuesday flyby was the dead booster's closest approach to our planet.A telescope on the Hawaiian island Maui first spotted the new space object in September. Its orbit seemed unnatural, following unusually close to Earth and remaining within the same plane as our planet. Most asteroids have tilted orbits, dipping above or below Earth as they journey around the sun."I was suspicious immediately," Paul Chodas, director of NASA's Center for Near-Earth Object Studies (CNEOS), <a href="https://www.nytimes.com/2020/12/01/science/nasa-rocket-orbit.html">told the New York Times</a>.Like Chodas, many scientists had suspected that this object was the Surveyor 2 booster, since reverse simulations of its orbit placed it so close to Earth in September 1966 that it could have easily come from our planet.To test the theory, scientists used a NASA telescope on Hawaii's Maunakea to watch 2020 SO as it flew past Earth. They logged the object's spectrum data — wavelengths of electromagnetic radiation that act like fingerprints for objects in space. Different wavelengths represent different chemical compounds.Scientists then compared the 2020 SO spectra to that of a known Centaur rocket booster, which has been orbiting Earth since it launched a satellite in 1971. The fingerprints matched."This conclusion was the result of a tremendous team effort," Vishnu Reddy, a planetary scientist at the University of Arizona who led the study, said in a <a href="https://www.nasa.gov/feature/new-data-confirm-2020-so-to-be-the-upper-centaur-rocket-booster-from-the-1960-s">press release</a>. "We were finally able to solve this mystery."
