NASA's next big $1 billion mission has a special delivery for Earth

<p></p><div class="KonaFilter image-container display-table center"><div><div class="image on-image"></div><p></p></div></div>Tonight, NASA will launch a rocket-fueled, minivan-sized spacecraft on a seven-year-journey through space - all for a pile of dirt. But this isn't just any dirt. This dirt could hold the key to <a href="http://www.businessinsider.com/nasa-osiris-rex-asteroid-sampling-mission-2016-9">answering some of our biggest questions about the universe</a>, such as where we came from, and why we exist.<p>The mission: <a href="https://www.nasa.gov/osiris-rex/">OSIRIS-Rex</a>, the United States' first asteroid sample return mission ... ever. The destination: An asteroid named <a href="https://www.nasa.gov/subject/6880/bennu/">Bennu</a>, a cosmic time capsule of sorts that contains dusty, 4.5-billion-year old relics from the birth of our solar system. It will take the spacecraft two years to traverse the 120-mile-distance between Earth and Bennu.</p><p>But the road trip doesn't end there. When OSIRIS-Rex finally reaches Bennu in September 2019, it will pump the brakes and slow down to a leisurely 63,000-mile-per-hour tread to match the speed at which Bennu hurtles around the sun. After surveying the asteroid for a spell, the spacecraft will try to enter&#xa0;the 1,614-foot-wide hunk of rock's weak orbit.</p><p>At about the <a href="http://www.wired.com/2016/09/watch-nasa-launch-asteroid-sampling-spacecraft/">size of the Empire State Building</a>, Bennu will be the smallest object NASA has ever attempted to orbit. And it won't be easy because, well, gravity (smaller objects mean less gravity, which makes orbiting the objects pretty tricky).</p><p>During its mile-long orbit around Bennu, OSIRIS-Rex will snap pictures every two hours, which will be transmitted back to Earth to help NASA keep the spacecraft on course.</p><p>The spacecraft, equipped with a suite of scientific instruments, will also take measurements of the asteroid to map its surface in 3D and get information about its geology.</p><p>It will also scope out&#xa0;the best spot for the mission's primary goal: Gathering a scoop of spacedirt that scientists back on Earth will use to tell the story of the birth of our solar system.</p><p>After a year, the spacecraft will cozy up to the asteroid (it will be too dangerous to maneuver a landing) and slowly stretch out its 10-foot-long arm toward Bennu's dusty surface where it will capture a few breaths of the asteroid's dirt and store it away in a capsule.</p><p>Then OSIRIS-Rex will begin its journey back to Earth and in September 2023, it will parachute down in the Utah desert, carrying some of the most important samples ever gathered from space.</p><p>If OSIRIS-Rex succeeds, it will not only bring home the largest asteroid sample ever. It will bring home the largest sample collected since the Apollo missions to the moon. And just a couple ounces of this dirt and gravel could help us finally explain the origin of life on our planet.</p><p>The spacecraft is scheduled to launch out of Cape Canaveral between 7:05 p.m. and 9:05 p.m. ET. NASA's live coverage will begin at 4:30 p.m. ET.

Tonight, NASA is launching a mission that could solve the mystery of life with just a few scoops of dirt

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.<br /><br />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.<br /><br />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."<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />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.<br /><br />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. <br /><br />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 <br /><br />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.<br /><br />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.<br /><br />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.<br /><br />Meanwhile, 61-year-old, Wilmore has logged 178 days in space and has 25 hours and 36 minutes of time on four spacewalks.<br /><br />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.<br /><br />If successful, the Crew Test Flight could queue up Boeing to begin flying routine trips to the space station on NASA's behalf. <br /><br />Boeing has already planned six manned missions for the platform over the next six years, the projected end of the ISS' operating lifespan.<br /><br />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.<br /><br />Boeing received over USD 4 billion in US federal funds to develop the Starliner, while SpaceX received about USD 2.6 billion.<br /><br /><b>SEE ALSO:<a href="https://www.businessinsider.in/stock-market/webstories/indegene-ipo-company-details-to-risk-factors-all-you-need-to-know/slidelist/109888922.cms" target="_blank"></a></b><br /><br /> <b><a href="https://www.businessinsider.in/stock-market/webstories/indegene-ipo-company-details-to-risk-factors-all-you-need-to-know/slidelist/109888922.cms" target="_blank">Indegene IPO: Company details to risk factors, all you need to know</a><a href="https://www.businessinsider.in/tech/news/worldwide-tablet-shipments-grow-in-q1-2024-after-two-years-of-decline/articleshow/109876390.cms" target="_blank"></a></b><br /><br /> <b><a href="https://www.businessinsider.in/tech/news/worldwide-tablet-shipments-grow-in-q1-2024-after-two-years-of-decline/articleshow/109876390.cms" target="_blank">Worldwide tablet shipments grow in Q1 2024 after two years of decline</a><a href="https://www.businessinsider.in/tech/news/asus-zenbook-duo-review/articleshow/109875023.cms" target="_blank"></a></b><br /><br /> <b><a href="https://www.businessinsider.in/tech/news/asus-zenbook-duo-review/articleshow/109875023.cms" target="_blank">Asus ZenBook Duo review – an excellent dual-screen laptop for multitaskers</a></b><br />

But he stressed that his plan to step down is not based on party affiliation. Rather, Bridenstine said, he would do so to ensure that the next leader of the agency could be someone with a longer-term relationship to Biden. </p><p>"The right question here is, 'What's in the best interest of NASA as an agency, and what's in the best interest of America's exploration program?'" Bridenstine told <a href="https://aviationweek.com/defense-space/space/nasa-chief-plans-step-aside-under-biden">Aviation Week.</a> "For that, what you need is somebody who has a close relationship with the president of the United States. You need somebody who is trusted by the administration. </p><p>"I think that I would not be the right person for that in a new administration," he added.</p><div type="image" title="nasa artemis moon astronaut spacesuit jim bridenstine" height="1386" width="1920" msid="79138995" hostid="261"></div><p>Since Trump tapped Bridenstine to lead NASA in April 2018, the agency announced its Artemis program, which now aims to send the first woman and next man to the moon by 2024. The program also aims to establish a sustainable human presence on the lunar surface by 2028. (The last time people walked on the moon <a href="https://airandspace.si.edu/explore-and-learn/topics/apollo/apollo-program/landing-missions/apollo17.cfm#:~:text=The%20Last%20Manned%20Lunar%20Landing&amp;text=Eugene%20Cernan%2C%20commander%20of%20Apollo,Moon%20since%20December%2014%2C%201972.972.">was in December 1972</a>.) </p><p>Bridenstine has also encouraged the development of commercial spaceflight in the US. During his tenure, SpaceX completed its <a href="https://www.businessinsider.com/spacex-crew-dragon-spaceship-nasa-astronauts-mission-landing-surprises-demo2-2020-8">first crewed mission in partnership with NASA</a> — the result of the agency's Commercial Crew Program, which started under the Obama administration.

Other private companies are also in competition to develop spacecraft that can land cargo and people on the lunar surface. </p><p>While helming NASA, Bridenstine has also overseen the launch of the <a href="https://www.businessinsider.com/nasa-perseverance-mars-rover-launch-2020-7">Mars Perseverance rover in July</a> and the Osiris-Rex spacecraft's successful touch-down and sample collection on <a href="https://www.businessinsider.com/nasa-asteroid-bennu-is-hollow-spinning-to-death-2020-11">the asteroid Bennu</a>.</p><div type="image" title="mars rover sample return mission perseverance" height="1080" width="1920" msid="79138998" hostid="261"></div><p>Biden's priorities differ from Trump's in a few key ways, <a href="https://www.reuters.com/article/us-usa-election-space-race/why-nasas-moonshot-boeing-bezos-and-musk-have-a-lot-riding-on-u-s-election-idUSKBN27F1C0">according to Reuters</a>. Biden will likely push back the Artemis mission's timeline by several years. He is also expected to propose extending US funding for the space station instead of handing control to private space companies by 2025, which the <keyword id="3798493" type="PERSON" weightage="60" keywordseo="trump-administration">Trump administration</keyword> had planned to do.</p><p>Biden's administration will, however, probably continue to promote competition between companies like SpaceX and Boeing for spaceflight contracts.</p><p>The full details of Biden's agenda for NASA are not yet fully known. The president-elect <a href="https://medium.com/@JoeBiden/my-statement-on-the-passing-of-john-hume-973d45770241">wrote in August</a> that he hopes to lead "a bold space program that will continue to send astronaut heroes to expand our exploration and scientific frontiers." </p><p>Bridenstine said he's optimistic about the future of space exploration under Biden — particularly when it comes to sending astronauts to the moon. </p><p>"We are in a good position as a country. If you look at the bipartisan, apolitical support that we have from members of Congress on both sides of the aisle … there is strong support for Artemis," Bridenstine told Aviation Week. </p>

The probe ramped up its thrusters to keep its antenna dish pointed toward Earth to send the data.</p><p>However, its connection with Earth didn't last much longer: The thrusters weren't designed to keep a spacecraft righted while plunging into Saturn at 78,000 mph.</p><p>Cassini began to tumble, breaking its last bond with Earth around 7:55 a.m. The signal was lost. And then the probe died.</p><p>It's unlikely that anyone saw it happen - <a href="http://www.businessinsider.com/cassini-death-will-it-be-visible-nasa-hubble-telescopes-2017-9">not even powerful telescopes</a> - but NASA surmises that its "faithful traveler from Earth" heated up to hundreds and then thousands of degrees, broke apart, disintegrated, and vaporized into a small, <a href="http://www.businessinsider.com/cassini-saturn-mission-death-plutonium-238-burn-up-2017-8">plutonium-laced meteor</a> that streaked above Saturn's clouds.</p><p><br>Before dying, Cassini's final communication traveled at light-speed from Saturn, taking just <a href="http://www.businessinsider.com/time-cassini-will-be-destroyed-timeline-2017-9">over 1 hour 23 minutes</a> to pass through the void of space and reach Earth. Giant radio dishes in Australia picked up the signal&#xa0;and forwarded the data to NASA's Jet Propulsion Laboratory (the heart of the Cassini mission).</br></p><p>Silence fell over the control<span>&#xa0;room, which was full of Cassini's scientific stewards and their family members. Everyone stared at their screens.&#xa0;</span>When the feed of data stopped,&#xa0;people&#xa0;clapped, then hugged, and many could be heard crying.</p><p>"The signal from the spacecraft is gone, and so will be the spacecraft in the next 45 seconds," said Earl Maize, an engineer at NASA's Jet Propulsion Laboratory who manages the Cassini mission, during a <a href="http://www.businessinsider.com/cassini-grand-finale-video-nasa-youtube-ustream-2017-9">live broadcast by NASA TV</a>. "This has been an incredible spacecraft, an incredible mission, and you're all an incredible team."</p><p>NASA could not&#xa0;confirm exactly what time Cassini met its doom, though the agency estimated it happened seconds to minutes after they lost touch with the probe.</p><p>One thing is clear, though: The space agency's $3.26-billion mission to explore Saturn is over.</p><p>"Thank you, Cassini, and farewell," Maize said during a press conference on Wednesday.</p><h2>Why NASA killed the Cassini probe</h2><p></p><div class="KonaFilter image-container display-table float_right"><div><div class="image on-image"></div><p></p></div></div>Cassini left Earth with 6,900 lbs of propellant in its tanks. This allowed it to adjust its orbit around Saturn and visit one moon after the next, leading to astonishing discoveries.<p>The probe discovered six new moons, mysterious "propeller objects" in <a href="http://www.businessinsider.com/earth-saturn-rings-image-cassini-2017-4">Saturn's rings</a>, documented a <a href="http://www.businessinsider.com/saturn-hexagon-storm-images-2017-5">giant hexagon</a> swirling atop the planet's north pole, photographed <a href="http://www.businessinsider.com/incredible-pictures-of-lakes-on-saturns-moon-titan-2013-12">hydrocarbon lakes</a> on Titan (Saturn's largest moon), and found a <a href="http://www.businessinsider.com/earth-water-ice-volume-versus-planets-moons-2016-11">vast ocean</a> of salty water - which may harbor alien life - below the icy crust of the moon <a href="http://www.businessinsider.com/saturns-moon-enceladus-cassini-ocean-life-global-salty-nasa-2015-9">Enceladus</a>.</p><p>In 2010, Cassini had enough propellant left to either fly by Uranus or Neptune, or continue to explore Saturn and its moons.</p><p>If it had flown past one of those planets and shot out into space, Cassini would have had enough <a href="http://www.businessinsider.com/nuclear-powered-spacecraft-nasa-history-2017-3">plutonium-238 fuel</a> to keep its electricity running for decades - just like the <a href="http://www.businessinsider.com/voyager-probes-mission-history-farthest-movie-2018-08">Voyager 1 and Voyager 2 probes</a>, which launched 40 years ago and have left the solar system.</p><p>But with so many questions about Saturn still unanswered, NASA decided to keep Cassini in orbit there - and doom it to its fiery "<a href="http://www.businessinsider.com/category/cassini-grand-finale">Grand Finale</a>" death in September 2017. With less than 90 lbs of propellant left on Friday, the spacecraft plunged &#xa0;to its demise. The scientists chose to kill the probe this way to avoid the&#xa0;risk that it could run out of fuel and crash into one of Saturn's&#xa0;potentially life-fostering moons.&#xa0;</p><p>"Because of <a href="http://www.businessinsider.com/nasa-planetary-protection-officer-job-opening-2017-7">planetary protection</a>, and our desire to go back to Enceladus, and go back to Titan," Jim Green, the leader of NASA's planetary <keyword id="41551" type="UNKNOWN" weightage="100" keywordseo="science">science</keyword> program, said during a Wednesday press briefing, "we must protect those bodies for future exploration."</p><p><br>Extending the mission at Saturn helped Cassini's controllers to pile on discovery after discovery.</br></p><p>The probe had discovered jets of water shooting out of Enceladus in 2005. This was astonishing enough, but the extension allowed Cassini to "taste" the spray, confirming the moon hides a <a href="http://www.businessinsider.com/saturns-moon-enceladus-cassini-ocean-life-global-salty-nasa-2015-9">salty ocean</a> below its ice-encrusted surface. Cassini also learned that Titan, too, may harbor its own <a href="http://www.businessinsider.com/water-space-volume-planets-moons-2016-10">habitable, subsurface seas</a>.</p><p>"To find that there's an ocean world so tiny with <a href="http://www.businessinsider.com/saturn-encealdus-hydrothermal-vent-aliens-2017-4">a possibility of life</a>, so far from the sun - 10 times farther from the sun than the Earth - has opened up our paradigm of where you might look for life," <a href="https://science.jpl.nasa.gov/people/Spilker/" target="_blank" rel="noopener noreferrer">Linda Spilker</a>, a Cassini project scientist and planetary scientist at NASA's JPL, said of Enceladus on Wednesday, "both within our own solar system and in the exoplanet systems beyond."</p><h2>Will there be a Cassini 2.0?</h2><p></p><div class="KonaFilter image-container display-table"><div><div class="image on-image"></div><p></p></div></div><p>Cassini is now dust falling through Saturn's clouds, and NASA has no other spacecraft there to study the planet, its rings, and fleet of moons.</p><p>But NASA is itching to fuel up more nuclear batteries, build a new spacecraft, and return to the planetary system.</p><p>"The observations by Cassini have been so remarkable for Enceladus and Titan, that ... we announced the inclusion of those two objects in our focused science program called <a href="https://solarsystem.nasa.gov/news/2017/05/05/nasa-receives-proposals-for-future-solar-system-mission" target="_blank" rel="noopener noreferrer">New Frontiers</a>," Green said on Wednesday.

The mission's called Enceladus Life Finder," Spilker told Business Insider.</p><p>She'll find out in December whether or not the proposal made the first cut, and gets a year to more deeply study and flesh out a mission plan. There are 11 competing proposals, about half of which also propose a return to Saturn.</p><p>"Certainly if my mission doesn't get selected, then I will be rooting for a mission to go back to the Saturn system," Spilker said.
