China claims to have successfully tested a secret "reusable" spacecraft amid crisis along the <keyword id="49399" type="PERSON" weightage="20" keywordseo="Line-of-Actual-Control">Line of Actual Control</keyword> (LAC) with India in Ladakh and confrontation with multiple nations in South China Sea. The Xinhua news agency on Sunday said that the vehicle returned to its "scheduled landing site" following a two-day mission in orbit after it was launched on a <keyword id="1705112" type="PERSON" weightage="20" keywordseo="Long-March-2F-rocket">Long March 2F rocket</keyword> on Friday from the Jiuquan Satellite Launch Center in the Gobi desert. Beijing claimed that the "successful flight marked the country's important breakthrough in reusable spacecraft research and is expected to offer convenient and low-cost round trip transport for the peaceful use of the space". An astronomer at Harvard Smithsonian Center for Astrophysics, Jonathan McDowell, using his Twitter handle speculated that the landing site may have been Taklamakan desert in northwest China. On Monday, India's DRDO successfully carried out the second test flight of its Hypersonic Technology Demonstrator Vehicle (HSTDV) using the indigenously developed scramjet propulsion system. It is a carrier vehicle for hypersonic and long-range cruise missiles, and will have multiple civilian applications, including the launching of small satellites at low cost. The previous flight in 2019 boosted to altitude on an Agni I first stage from Kalam Island, McDowell said. <div type="Article" hostid="261" msid="77971186" title="India successfully tests its hypersonic missile carrier than can also launch satellites into orbit" mstype="2" mssubtype="0"></div> The Chinese mission, which is shrouded in mystery comes at a time when Beijing and New Delhi are locked in a violent face-off along the Line of Actual Control (LAC) in Ladakh. Last week, the Indian Army captured key ridges on the south bank of the Pangong Tso, in a tit-for-tat move, effectively taking control of all the strategic heights in the area along the LoC in Ladakh. Incidentally, Chinese President Xi Jinping canceled his trip to Pakistan in a last-minute decision. Meanwhile, two Australian journalists facing security threat from the Chinese authorities, were evacuated from China in a diplomatic standoff. The Australian Broadcasting Corporation's Bill Birtles and the Australian Financial Review's Mike Smith landed in Sydney on Tuesday. As the US-China relationship has entered a Cold-War like situation, the Xi Jinping regime has deployed PLA Navy, China Coast Guard and maritime militia to claim its sovereignty over South China Sea. Since the outbreak of coronavirus pandemic which originated in the Wuhan city of its Hubei province, Beijing has sent fishing boats into the waters adjacent to Indonesia's Natuna Islands and deployed survey vessels into the exclusive economic zones of Brunei, Vietnam, Malaysia and the Philippines. The Chinese Communist Party (CCP) regime has also created two new administrative districts in the disputed islands of the Paracels and Spratlys and carried out missile tests in the disputed area.

The increase in rocket launches by commercial <keyword id="11895441" type="UNKNOWN" weightage="60" keywordseo="space" source="Orion">space</keyword> companies such as Elon Musk's SpaceX, Jeff Bezos' Blue Origin, and Richard Branson's Virgin Galactic "could have a significant cumulative effect on climate," the study said. This is because of the amount of carbon gases and nitrogen oxides being produced with each <keyword id="6356110" type="UNKNOWN" weightage="60" keywordseo="launch" source="Orion">launch</keyword>, the study said.The study found that the concentration of nitrogen oxides, which an ascending rocket releases into two cubic kilometers of atmospheric air, was considered "hazardous to human health" under the World Health Organization's (WHO) standards."The impact on the atmosphere will be a crucial factor requiring careful consideration in the design of future rocket launches," the study's authors, Ioannis Kokkinakis and Dimitris Drikakis, wrote.As the number of commercial rocket rides climb, the consequent pollution in the atmosphere must be looked into, the authors added.A Blue Origin spokesperson told Insider that the New Shepard rocket is "fueled by highly efficient and clean liquid oxygen and hydrogen" and the only byproduct is "water vapor with no carbon emissions."Blue Origin is planning its fifth human flight to the edge of space in May after already <a href="https://www.businessinsider.com/blue-origin-married-couple-spacex-virgin-galactic-rocket-launch-2022-3">launching its resuable New Shepard rocket</a> in March. Its <a href="https://www.businessinsider.com/watch-live-jeff-bezos-blue-origin-space-launch-2021-7">first mission to launch humans to space</a> was in July when Bezos and his brother were passengers onboard.SpaceX, which builds reusable rockets, completed 31 flights in 2021, which was a record high for the company. It plans to <a href="https://www.businessinsider.com/elon-musk-spacex-goal-60-falcon-rocket-launches-this-year-2022-3">launch 60 rockets</a> in 2022, Musk said <a href="https://twitter.com/elonmusk/status/1508540042817376256">in a tweet</a> in March. Meanwhile, Virgin Galactic said it's planning to <a href="https://www.businessinsider.com/virgin-galactic-space-tourism-flights-2023-new-ship-2021-11">ramp up tourist flights next year</a>, aiming to send customers to space three times per month with its reusable rocket.

Pollution from SpaceX, Blue Origin, Virgin Galactic's rockets could harm human health as well as Earth's climate, study says

<a title_source="Mario Anzuoni/Reuters" title_caption="SpaceX CEO Elon Musk after unveiling the Dragon V2 spacecraft in Hawthorne, California, on May 29." class="zoomin" href="https://static-ssl.businessinsider.com/image/544ff061ecad04c143b3adc5-960/elon%20musk%20spacex.jpg"></a>Mario Anzuoni/ReutersSpaceX CEO Elon Musk after unveiling the Dragon V2 spacecraft in Hawthorne, California, on May 29.The first SpaceX launch of 2015 is scheduled for Tuesday, January 6, at <a href="http://www.nasa.gov/mission_pages/station/structure/launch/index.html#.VKaycWTF_-o">6:20 a.m. EST</a>, and it could be a game-changing event for reusable rocket technology.
But the most important part of the launch will not be what goes up, but what comes down. After the Falcon 9 rocket has emptied most of its fuel, it will detach from the Dragon spacecraft.
That's when things get interesting, as the rocket, using GPS tracking, navigates its way down to a floating platform in the Atlantic Ocean. But it won't be easy.
SpaceX founder and CEO, Elon Musk will <a href="http://t.co/DvCbw4kTJy">conduct an AMA on Reddit about the launch at 9:00 pm EST</a>.
<h3>Reusable Rockets</h3>
No first-stage rocket has ever been recovered for reuse. If successful on Tuesday, the company will set a new standard in space exploration - one that could eventually cut the cost of space travel by a factor of 100, <a href="http://www.space.com/27992-spacex-private-cargo-launch-delay.html?utm_content=buffere71f7&amp;utm_medium=social&amp;utm_source=twitter.com&amp;utm_campaign=buffer">according to Musk</a>.
Building a rocket that can be used more than once is an extremely important step in ultimately <a href="http://www.businessinsider.com/elon-musk-and-colbert-talk-spacex-mars-2014-7">sending a manned space mission to and from Mars</a> that could use the rocket to land and, more importantly, leave Mars to return to Earth.
In addition to possibly changing spaceflight forever, the launch will also ferry 3,700 pounds of <keyword id="41551" type="ENTERTAINMENT" weightage="100" keywordseo="science">science</keyword> experiments, spare parts, food, water, and other supplies to the International Space Station on the Dragon spacecraft. Then, the excitement will start.
It's a risky endeavor, which Elon Musk estimates has only a 50% probability of success. "During previous attempts, we could only expect a landing accuracy of within 10 kilometers (6.2 miles). For this attempt, we're targeting a landing accuracy of within 10 meters (33 feet)," SpaceX said in <a href="http://www.spacex.com/news/2014/12/16/x-marks-spot-falcon-9-attempts-ocean-platform-landing">a statement</a>.
Doing this will be like "trying to balance a rubber broomstick on your hand in the middle of a wind storm," the statement said.
On Jan.5 , Musk <a href="https://twitter.com/elonmusk/status/552182273865699328">tweeted a photo of the drone ship</a> navigating its way into position to prep for the landing:

<h3>A Drone Ship For A Remote Rocket</h3>
Last year, SpaceX began their the resuable rocket endeavor with multiple attempts to land a rocket softly in the ocean. A soft landing maintains the integrity and reusability of the rocket. But after the company <a href="http://www.businessinsider.com/elon-musk-will-make-an-important-spacex-announcement-at-1-pm-edt-2014-4">in April</a> successfully achieved the first soft landing in history, the rocket toppled sideways in the high seas, damaging it beyond repair.
Because landing in the water won't work, the team has turned to something else.
The new plan? Create a self-stabilizing floating platform to sit in the ocean and wait for the rocket's return.
"I think we've got a chance of landing on a floating landing platform," Elon Musk said in October at the <a href="https://www.youtube.com/watch?v=SOpmaLY9XdI#t=430">MIT AeroAstro Centennial Symposium</a>. "And if we land on that, then I think we'll be able to re-fly that booster."
<a href="http://www.businessinsider.com/elon-musk-rockets-that-land-at-sea-2014-11">Just last month</a>, Musk tweeted images of the football-field-long platform. SpaceX plans to use GPS tracking, the rocket's newly attached "X-wings," and other technology to help safely guide the multimillion-dollar Falcon 9 onto the platform.
The hypersonic X-wings, shown in the picture above, will deploy upon descent and help the rocket steer onto the platform. The rocket is about 70 feet wide, and the platform has a width about three times the size of that, so precision is key in this game-changing attempt.
"It's probably not more than a 50% chance or less of landing it on the platform," Musk said, still seeming optimistic at the <a href="https://www.youtube.com/watch?v=SOpmaLY9XdI">MIT AeroAstro Centennial Symposium</a>. "But there's at least a dozen launches that will occur over the next 12 months, and I think it's quite likely, probably 80 to 90% likely, that one of those flights will be able to land and re-fly. So I think we're quite close."

Tuesday's SpaceX Launch Could Forever Change Spaceflight

<a title_source="Mario Anzuoni/Reuters" title_caption="SpaceX CEO Elon Musk after unveiling the Dragon V2 spacecraft in Hawthorne, California, on May 29." class="zoomin" href="https://static-ssl.businessinsider.com/image/544ff061ecad04c143b3adc5-960/elon%20musk%20spacex.jpg"></a>Mario Anzuoni/ReutersSpaceX CEO Elon Musk after unveiling the Dragon V2 spacecraft in Hawthorne, California, on May 29.After several delays and reschedulings, SpaceX is set to launch a Falcon 9 rocket with a Dragon spacecraft full of cargo destined for the International Space Station (ISS) on Saturday, January 10, at <a href="http://www.nasa.gov/mission_pages/station/structure/launch/index.html#.VKaycWTF_-o">4:47 a.m. EST</a>.
But what's most important about this launch isn't the going up - it's the Falcon 9 rocket's descent, which will include a game-changing test of SpaceX's reusable rocket technology.
The launch was originally scheduled to launch earlier this week, on Tuesday, January 6, but due to a technical glitch with one of the rocket's engines the attempt was scrubbed.
"During the terminal count engineers observed drift on one of the two thrust vector actuators on the second stage that would likely have caused an automatic abort. Engineers called a hold in order to take a closer look," <a href="http://www.spacex.com/webcast/">SpaceX said in a statement</a>.
Now, the launch is scheduled to happen on January 10, at 4:47 am EST.
In addition to possibly changing spaceflight forever, the launch will also ferry 5,200 pounds of <keyword id="41551" type="ENTERTAINMENT" weightage="100" keywordseo="science">science</keyword> experiments, spare parts, food, water, and other supplies to the ISS on the Dragon spacecraft.
After the rocket blasts off, the Dragon capsule separates and heads off to the ISS. That's when things get really interesting.
The rocket, using GPS tracking, will navigate its way down to a floating platform in the Atlantic Ocean, and land vertically without damage. At the end of the day, it should look something like the image below, made by SpaceX fan and Reddtior <a href="https://twitter.com/zlsadesign">Jon Ross</a> on <a href="http://zlsa.github.io/">ZLSA Design</a>.

<h2>Reusable Rockets</h2>
This task won't be easy. No first-stage rocket has ever been recovered for reuse. If successful on Saturday, January 10, the company will set a new standard in space exploration - one that could eventually cut the cost of space travel by a factor of 100, <a href="http://www.space.com/27992-spacex-private-cargo-launch-delay.html?utm_content=buffere71f7&amp;utm_medium=social&amp;utm_source=twitter.com&amp;utm_campaign=buffer">according to Musk</a>.
So far, each SpaceX resupply mission has used a different rocket costing around $60 million each, but if this launch is successful that could change. The cost of rockets, alone, is partly why reusable rocket technology is so important. Reuse could immediately save $60 million from SpaceX's next launch - scheduled for Jan. 29 - if the Falcon 9 rocket is recovered undamaged on Saturday.
Building a rocket that can be used more than once is also an extremely important step in ultimately <a href="http://www.businessinsider.com/elon-musk-and-colbert-talk-spacex-mars-2014-7">sending a manned space mission to and from Mars</a> that could use the rocket to land and, more importantly, leave the Red planet to return to Earth.
It's a risky endeavor, which Elon Musk estimates has only a 50% probability of success. "During previous attempts, we could only expect a landing accuracy of within 10 kilometers (6.2 miles).
