NASA’s DART spacecraft successfully slammed into a distant asteroid at hypersonic speed on Monday in the world’s first test of a planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth.
Humanity’s first attempt to alter the motion of an asteroid or any celestial body played out in a NASA webcast from the mission operations center outside Washington, DC, 10 months after DART was launched.
The livestream showed images taken by DART’s camera as the cube-shaped “impactor” vehicle, no bigger than a vending machine with two rectangular solar arrays, streaked into the asteroid Dimorphos, about the size of a football stadium, at 7:14 pm EDT (23:14 GMT) some 6.8 million miles (11 million km) from Earth.

The $330 million (roughly Rs. 2,683 crore) mission, some seven years in development, was devised to determine if a spacecraft is capable of changing the trajectory of an asteroid through sheer kinetic force, nudging it off course just enough to keep Earth out of harm’s way.
Whether the experiment succeeded beyond accomplishing its intended impact will not be known until further ground-based telescope observations of the asteroid next month. But NASA officials hailed the immediate outcome of Monday’s test, saying the spacecraft achieved its purpose.
“NASA works for the benefit of humanity, so for us it’s the ultimate fulfillment of our mission to do something like this – a technology demonstration that, who knows, some day could save our home,” NASA Deputy Administrator Pam Melroy, a retired astronaut, said minutes after the impact.
DART, launched by a SpaceX rocket in November 2021, made most of its voyage under the guidance of NASA’s flight directors, with control handed over to an autonomous on-board navigation system in the final hours of the journey.
Monday evening’s bullseye impact was monitored in near real time from the mission operations center at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.
Cheers erupted from the control room as second-by-second images of the target asteroid, captured by DART’s onboard camera, grew larger and ultimately filled the TV screen of NASA’s live webcast just before the signal was lost, confirming the spacecraft had crashed into Dimorphos.
DART’s celestial target was an oblong asteroid “moonlet” about 560 feet (170 meters) in diameter that orbits a parent asteroid five times larger called Didymos as part of a binary pair with the same name, the Greek word for twin.
Neither object presents any actual threat to Earth, and NASA scientists said their DART test could not create a new hazard by mistake.
Dimorphos and Didymos are both tiny compared with the cataclysmic Chicxulub asteroid that struck Earth some 66 million years ago, wiping out about three-quarters of the world’s plant and animal species including the dinosaurs.
Smaller asteroids are far more common and present a greater theoretical concern in the near term, making the Didymos pair suitable test subjects for their size, according to NASA scientists and planetary defense experts. A Dimorphos-sized asteroid, while not capable of posing a planet-wide threat, could level a major city with a direct hit.
Also, the two asteroids’ relative proximity to Earth and dual configuration make them ideal for the first proof-of-concept mission of DART, short for Double Asteroid Redirection Test.
Robotic suicide mission
The mission represented a rare instance in which a NASA spacecraft had to crash to succeed. DART flew directly into Dimorphos at 15,000 miles per hour (24,000 kph), creating the force scientists hope will be enough to shift its orbital track closer to the parent asteroid.
APL engineers said the spacecraft was presumably smashed to bits and left a small impact crater in the boulder-strewn surface of the asteroid.
The DART team said it expects to shorten the orbital path of Dimorphos by 10 minutes but would consider at least 73 seconds a success, proving the exercise as a viable technique to deflect an asteroid on a collision course with Earth – if one were ever discovered.
A nudge to an asteroid millions of miles away years in advance could be sufficient to safely reroute it.
Earlier calculations of the starting location and orbital period of Dimorphos were made during a six-day observation period in July and will be compared with post-impact measurements made in October to determine whether the asteroid budged and by how much.
Monday’s test also was observed by a camera mounted on a briefcase-sized mini-spacecraft released from DART days in advance, as well as by ground-based observatories and the Hubble and Webb space telescopes, but images from those were not immediately available.
DART is the latest of several NASA missions in recent years to explore and interact with asteroids, primordial rocky remnants from the solar system’s formation more than 4.5 billion years ago.
Last year, NASA launched a probe on a voyage to the Trojan asteroid clusters orbiting near Jupiter, while the grab-and-go spacecraft OSIRIS-REx is on its way back to Earth with a sample collected in October 2020 from the asteroid Bennu.
The Dimorphos moonlet is one of the smallest astronomical objects to receive a permanent name and is one of 27,500 known near-Earth asteroids of all sizes tracked by NASA. Although none are known to pose a foreseeable hazard to humankind, NASA estimates that many more asteroids remain undetected in the near-Earth vicinity.

Neuralink Expected to Begin Human Clinical Trials in Six Months, Elon Musk Says
By Reuters | Updated: 1 December 2022
Elon Musk said on Wednesday a wireless device developed by his brain chip company Neuralink is expected to begin human clinical trials in six months.
The company is developing brain chip interfaces that it says could enable disabled patients to move and communicate again. Based in the San Francisco Bay Area and Austin, Texas, Neuralink has in recent years been conducting tests on animals as it seeks US regulatory approval to begin clinical trials in people.
“We want to be extremely careful and certain that it will work well before putting a device into a human but we’ve submitted I think most of our paperwork to the FDA and probably in about six months we should be able to upload Neuralink in a human,” Musk said during a much-awaited public update on the device.
The event was originally planned for October 31 but Musk postponed it just days before without giving a reason.
Neuralink’s last public presentation, more than a year ago, involved a monkey with a brain chip that played a computer game by thinking alone.
Musk is known for lofty goals such as colonizing Mars and saving humanity. His ambitions for Neuralink, which he launched in 2016, are of the same grand scale. He wants to develop a chip that would allow the brain to control complex electronic devices and eventually allow people with paralysis to regain motor function and treat brain diseases such as Parkinson’s, dementia and Alzheimer’s. He also talks about melding the brain with artificial intelligence.
Neuralink, however, is running behind schedule. Musk said in a 2019 presentation he was aiming to receive regulatory approval by the end of 2020. He then said at a conference in late 2021 that he hoped to start human trials this year.
Neuralink has repeatedly missed internal deadlines to gain US Food and Drug Administration (FDA) approval to start human trials, current and former employees have said. Musk approached competitor Synchron earlier this year about a potential investment after he expressed frustration to Neuralink employees about their slow progress, Reuters reported in August.
Synchron crossed a major milestone in July by implanting its device in a patient in the United States for the first time. It received US regulatory clearance for human trials in 2021 and has completed studies in four people in Australia.

NASA’s Orion Spacecraft Enters Lunar Orbit a Week After Artemis I Launch
By Agence France-Presse | Updated: 26 November 2022
NASA’s Orion spacecraft was placed in lunar orbit Friday, officials said, as the much-delayed Moon mission proceeded successfully.
A little over a week after the spacecraft blasted off from Florida bound for the Moon, flight controllers “successfully performed a burn to insert Orion into a distant retrograde orbit,” the US space agency said on its website.
The spacecraft is to take astronauts to the Moon in the coming years — the first to set foot on its surface since the last Apollo mission in 1972.
This first test flight, without a crew on board, aims to ensure that the vehicle is safe.
“The orbit is distant in that Orion will fly about 40,000 miles above the Moon,” NASA said.
While in lunar orbit, flight controllers will monitor key systems and perform checkouts while in the environment of deep space, the agency said.
It will take Orion about a week to complete half an orbit around the Moon. It will then exit the orbit for the return journey home, according to NASA.
On Saturday, the ship is expected to go up to 40,000 miles beyond the Moon, a record for a habitable capsule. The current record is held by the Apollo 13 spacecraft at 248,655 miles (400,171 km) from Earth.
It will then begin the journey back to Earth, with a landing in the Pacific Ocean scheduled for December 11, after just over 25 days of flight.
The success of this mission will determine the future of the Artemis 2 mission, which will take astronauts around the Moon without landing, then Artemis 3, which will finally mark the return of humans to the lunar surface.
Those missions are scheduled to take place in 2024 and 2025, respectively.
ISRO’s RH200 Sounding Rocket Registers 200th Consecutive Successful Launch
By Press Trust of India | Updated: 24 November 2022
ISRO on Wednesday announced that RH200, the versatile sounding rocket of the Indian space agency, has registered its 200th consecutive successful launch from the shores of Thumba, Thiruvananthapuram. The Indian Space Research Organisation (ISRO) has termed it a “historic moment”. It was witnessed by former President Ram Nath Kovind and ISRO chairman S Somanath, among others.
The successful flight of RH200 took off from the Thumba Equatorial Rocket Launching Station (TERLS).
“Indian sounding rockets are used as privileged tools for the scientific community for carrying out experiments on meteorology, astronomy and similar branches of space physics,” an ISRO statement said.
Campaigns such as Equatorial ElectroJet (EEJ), Leonid Meteor Shower (LMS), Indian Middle Atmosphere Programme (IMAP), Monsoon Experiment (MONEX), Middle Atmosphere Dynamics (MIDAS), and Sooryagrahan-2010 have been conducted using the sounding rocket platform for scientific exploration of the Earth’s atmosphere, it said.
The Rohini Sounding Rocket (RSR) series have been the forerunners for ISRO’s heavier and more complex launch vehicles, with a continued usage even today for atmospheric and meteorological studies, the national space agency headquartered here said.
“The 200th consecutive successful flight stands testimony to the commitment of Indian rocket scientists towards unmatched reliability demonstrated over the years,” it said.
Meanwhile, ISRO is all set to launch PSLV-C54/ EOS-06 mission with Oceansat-3 and eight nano satellites, including one from Bhutan, from the Sriharikota spaceport on November 26. The launch is scheduled at 11.56am on Saturday, the national space agency said on Sunday.
Last week, ISRO announced that the payload capability of India’s heaviest LVM3 rocket has been enhanced by up to 450kg with a successful engine test. According to the Indian Space Research Organisation, the CE20 cryogenic engine indigenously developed for Launch Vehicle Mark 3 (LVM3) was subjected to a successful hot test at an uprated thrust level of 21.8 tonnes for the first time on November 9, according to the country’s national space agency.

Vikram-S, India’s First Private Rocket, Successfully Launched Into Space by Skyroot Aerospace
By Agencies | Updated: 18 November 2022
India launched its first privately developed rocket, the Vikram-S, on Friday, a milestone in the country’s effort to create a commercial space industry. The 545-kg rocket developed by space startup Skyroot took off from the Indian space agency’s launch site near Chennai. The rocket has the capability of reaching Mach 5 – five times the speed of sound – and carrying a payload of 83 kg. Video footage showed the rocket taking off from the space centre, leaving a plume of smoke and fire in its trail.
Hyderabad-based Skyroot, founded in 2018 and backed by Singapore sovereign wealth fund GIC, was the first space startup to sign an agreement to use Indian Space Research Organisation (ISRO) launch and test facilities after the government opened the door to private companies in 2020.
It has raised Rs. 530 crore so far and employs about 200 people. Close to 100 people have been involved in its maiden launch project, the company said.
The rocket is expected to reach an altitude of about 81 kilometres before splashing down in about 5 minutes.
With the launch of Vikram-S, Skyroot has become the first private space company in India to launch a rocket into space, heralding a new era for the space sector which was opened up in 2020 to facilitate private sector participation.
Skyroot’s launch vehicles are named ‘Vikram’ as a tribute to the founder of the Indian space programme and renowned scientist Vikram Sarabhai. The startup was the first to sign a memorandum of understanding with ISRO for launching its rockets. It aims to disrupt entry barriers to cost-efficient satellite launch services and space-flight by advancing its mission to make spaceflights affordable, reliable and regular for all, the statement said.
“The maiden launch by a new Startup has significantly enhanced the credibility for Indian private space players around the globe. The capability that the sector has been claiming has been demonstrated in Space. Since its inception in 2018, Skyroot has come a long way in delivering its expertise in manufacturing of small lift launch vehicles by launching India’s first private rocket which was manufactured in just two years. The Vikram-S rocket’s success will further validate most of the technologies in the ‘Vikram’ series of space launch vehicles planned by Skyroot for the coming years. India’s space economy is set to grow to $13 billion (roughly Rs.1,06,222 crore) and the space launch segment is estimated to grow the fastest by 2025 at a CAGR of 13 percent which will be further spurred by growing private participation, latest technology adoption and low cost of launch services and this launch is a major landmark for this growth to take place in the coming years”, Lt. Gen. AK Bhatt, director general, Indian Space Association said in a prepared statement.
SpaceX Employees Fired for Criticising Elon Musk Accuse Firm of Violating US Labour Law
By Associated Press | Updated: 18 November 2022
Several SpaceX employees who were fired after circulating an open letter calling out CEO Elon Musk’s behaviour have filed a complaint accusing the company of violating labour laws.
The complaint, made Wednesday to the National Labor Relations Board, details the aftermath of what allegedly happened inside SpaceX after employees circulated the letter in June, which, among other things, called on executives to condemn Musk’s public behaviour on Twitter — including making light of allegations he sexually harassed a flight attendant — and hold everyone accountable for unacceptable conduct.
The letter was sent weeks after a media report surfaced that Musk paid $250,000 (roughly Rs. 2,04,27,920) to the flight attendant to quash a potential sexual harassment lawsuit against him. The billionaire has denied the allegations.
Employees in their letter urged SpaceX to uniformly enforce its policy against unacceptable behaviour and commit to a transparent process for responses to claims of misconduct. A day later, Paige Holland-Thielen and four other employees who participated in organizing the letter were fired, according to the filing, which was made by Holland-Thielen to a regional NLRB office in California. Four additional employees were fired weeks later for their involvement in the letter.
A company spokesperson did not immediately respond to a request for comment.
Musk, who is the CEO of Tesla and SpaceX and is currently running Twitter, prefers to do things his own way even if that means running afoul of rules and regulations. He’s currently in a defiant fight with Civil Rights department, a California regulator that is suing Tesla for rampant racial discrimination.
Some view Musk’s management style as autocratic and demanding, as evidenced by a recent email he sent to Twitter staff giving them until Thursday evening to decide whether they want to remain a part of the business. Musk wrote that employees “will need to be extremely hardcore” to build “a breakthrough Twitter 2.0″ and that long hours at high intensity will be needed for success.
A number of engineers also said on Twitter they were fired last week after saying something critical of Musk, either publicly on Twitter or on an internal messaging board for Twitter employees.
In a statement, Holland-Thielen said as a woman engineer at SpaceX, she experienced “deep cultural problems” and comforted colleagues who had experienced similar issues.
“It was clear that this culture was created from the top level,” she said.
Still, she said part of what she liked about the company was that any person could escalate issues to leadership and be taken seriously.
“We drafted the letter to communicate to the executive staff on their terms and show how their lack of action created tangible barriers to the long term success of the mission,” Holland-Thielen said. “We never imagined that SpaceX would fire us for trying to help the company succeed.”
The firings coincide with Musk’s $44 billion (roughly Rs. 3,37,465 crore) buyout of Twitter. Around the same time, the billionaire used a sexual term to make fun of Microsoft co-founder Bill Gates’ belly and also posted a poop emoji during an online discussion with then-Twitter CEO Parag Agrawal.
After terminating the first set of employees, SpaceX allegedly interrogated dozens of others over the next two months in private meetings, telling them they couldn’t disclose those conversations to anyone else due to attorney-client privilege, according to the complaint. Four additional employees who helped draft or share the letter were fired in July and August, the filing said, adding up to nine terminations in total.
“Management used this ‘ends justifies the means’ philosophy to turn a blind eye to the ongoing mistreatment, harassment, and abuse reported by my colleagues, much of which was directly encouraged and inspired by the words and actions of the CEO,” said Tom Moline, who was also fired from SpaceX after organizing the letter.
Jeffery Pfeffer, a professor who specializes in organizational behaviour at Stanford University’s business school, said that the allegations were hardly a surprise given Musk’s leadership style at Twitter. Musk’s success at companies like Tesla and SpaceX have created what he labeled as hubris under the false notion that it was “all about individual genius.”
“Powerful people get to break the rules. They don’t think they are bound by the same conventions as other people,” Pfeffer said, criticizing Musk’s behavior. He said it showed the arrogance of Musk, one of the world’s richest men: “Why would he think he is a mere mortal?”
