Boeing postpones launch of Starliner space capsule over valve problem | Space

Cancellation of inaugural crewed space mission comes as Boeing is under fire over safety record at its aviation arm.

Boeing has called off the inaugural crewed flight CST-100 Starliner space capsule after engineers detected an issue with a rocket valve.

The decision to call off the launch on Monday came two hours before the scheduled liftoff and about an hour after two NASA astronauts had strapped into the spacecraft.

The postponement, blamed on a problem with a valve in the Atlas V rocket, was announced during a live NASA webcast.

“Standing down on tonight’s attempt to launch,” NASA chief Bill Nelson said in a post on X.

“As I’ve said before, @NASA’s first priority is safety. We go when we’re ready.”

It was not immediately clear how long it would take to address the problem, but the next available launch windows for the launch are Tuesday, Thursday and Friday nights.

The Starliner had been due to transport NASA astronauts Butch Wilmore and Suni Williams to the International Space Station (ISS), where they would have spent a week before returning to Earth.

The Starliner’s inaugural voyage to the ISS has been closely watched as a sign of Boeing’s ability to rival Elon Musk’s SpaceX for NASA contracts.

NASA in 2014 awarded multibillion-dollar contracts to Boeing and SpaceX to develop space capsules for the space agency to ferry astronauts and cargo into space.

The contracts marked the start of a shift by NASA towards public-private partnerships following the end of its space shuttle program.

SpaceX’s Dragon successfully transported astronauts to the ISS in 2020, marking the first time NASA astronauts had launched from US soil in a commercially-built spacecraft.

Starliner flew its first uncrewed mission to ISS in 2022, after an unsuccessful attempt three years earlier.

Monday’s launch cancellation comes at a difficult time for Boeing as the company grapples with several probes into alleged safety lapses at its aviation division.

Why does NASA want a time zone on the moon? | Space News

NASA has been tasked with determining a standard time zone for the moon, but it’s more complicated than you might think.

The United States government has tasked its space agency, NASA, with establishing a standard time zone for the moon, which will be known as Coordinated Lunar Time (CLT).

In a memo issued on April 2, the US Office of Science and Technology Policy (OSTP) stated: “Federal agencies will develop celestial time standardisation with an initial focus on the lunar surface and missions operating in Cislunar space [the area within the moon’s orbit], with sufficient traceability to support missions to other celestial bodies.” “Traceability” means that CLT can be kept in sync with time zones on Earth.

The memo outlined the following features for the new CLT:

  • Traceability to Coordinated Universal Time (UTC – a compromise for both English and French speakers);
  • Accuracy sufficient to support precision navigation and science;
  • Resilience to loss of contact with Earth (meaning CLT can operate independently of Earth); and
  • Scalability to space environments beyond the Earth-moon system (meaning other space stations beyond the moon would be able to use CLT as well).

Don’t expect your favourite time zone and calendar apps to have CLT as an option yet; NASA has until the end of 2026 to establish CLT.

Why does the moon need its own time zone?

In layman’s terms, we need a reliable “lunar time” earth-syncing system because lower gravity on the moon causes time to move slightly faster there than on Earth – by just 58.7 microseconds (there are 1 million microseconds in a single second) faster within every 24 Earth hours.

This is not science fiction, even though it is a main feature of Hollywood blockbusters such as Interstellar. Known as “gravitational time dilation”, the passage of time is impacted by gravity.

Although small, these time discrepancies can cause issues with syncing satellites and space stations in lunar orbit.

An unnamed OSTP official told Reuters: “Imagine if the world wasn’t syncing their clocks to the same time – how disruptive that might be and how challenging everyday things become.”

How would we tell time on the moon?

Earth uses UTC or Coordinated Universal Time to sync time zones around the world. UTC is determined by more than 400 atomic clocks that are maintained in national “time laboratories” in about 30 countries around the world. An atomic clock uses the vibrations of atoms to achieve extreme precision in keeping track of time.

Similar atomic clocks would be placed on the moon to get an accurate time reading.

Known as Positioning, Navigation and Timing (PNT), this precision-timing system allows communications systems to measure and keep accurate timing. The Ordnance Survey, the British organisation that has been producing maps since 1791, explains that PNT has three core elements:

  • Positioning – the ability to precisely determine one’s location and orientation, predominantly two dimensionally on a printed map, although three-dimensional orientation can be determined when required.
  • Navigation – the ability to determine both the current and desired position (either relative or absolute), and apply corrections to course, orientation and speed to reach a desired position from anywhere in the world, from sub-surface (below the Earth’s surface) to surface, and from surface to space.
  • Timing – the ability to maintain accurate and precise time from anywhere in the world.

Does NASA have plans for time zones in other parts of outer space?

Although there has been no mention of time zones on other planets, in 2019, NASA’s Deep Space Atomic Clock (DSAC) mission tested an atomic clock to improve spacecraft navigation in deep space. The DSAC mission, on SpaceX’s Falcon Heavy rocket, was launched on June 22, 2019. The rocket tested the atomic clock in Earth’s orbit for one year.

Typically, spacecraft keep accurate time by bouncing signals to atomic clocks on Earth and then the signal is sent back to the spacecraft. In this mission, the on-board atomic clock was tested to keep precise time without relying on this two-way communication between the spacecraft and the atomic clocks on Earth. The accuracy of the timing is tied to getting accurate positioning, while helping the spacecraft reach the intended location in space successfully.

As NASA’s Jet Propulsion Laboratory, the centre for robotic exploration of the solar system, explains: “A two-way system that sends a signal from Earth to a spacecraft, back to Earth and then to the spacecraft again would take an average of 40 minutes. Imagine if the GPS on your phone took 40 minutes to calculate your position. You might miss your turn or be several exits down the highway before it caught up with you. If humans travel to the Red Planet [Mars], it would be better if the system was one-way, allowing the explorers to immediately determine their current position rather than waiting for that information to come back from Earth.”

The mission successfully ended in 2021, with the on-board atomic clock maintaining the correct timing and navigational positioning.

Russia’s Angara A5 rocket blasts off into space after two aborted launches | Space News

Russia wants to use rocket’s cargo capacities to deliver modules for a future rival to the International Space Station.

Russia has launched its Angara A5 rocket from a space facility in the country’s far east after technical glitches prompted officials to abort missions at the last minute for two days in a row.

Thursday’s launch of the new space vehicle is intended to showcase Russia’s post-Soviet space ambitions, and the growing role played by the Vostochny Cosmodrome, which is located in the forests of the Amur region bordering China.

Launch attempts on Tuesday and Wednesday were cancelled due to a failure in a pressurising system in an oxidiser tank and in the engine control system, according to Russian space agency Roscosmos.

Minutes after takeoff, the rocket was travelling at more than 25,000 kilometres per hour and entered orbit.

“With this launch, flight design tests of the Amur space rocket complex with Angara heavy-class launch vehicles on Vostochny began,” Roscosmos announced on social media.

“The rocket worked according to plan. The upper stage separated … and is currently putting the test payload into target orbit.”

ISS rival eyed

Russia began the Angara project a few years after the 1991 fall of the Soviet Union as a Russian-made launch vehicle that would ensure access to space even without the Baikonur Cosmodrome which it rents from Kazakhstan.

The development of the Angara A5, a heavy booster rocket designed to ferry tonnes of equipment into space, has been beset by delays.

The first Angara A5 test flight took place in 2014, and another followed in 2020, both from the Plesetsk space facility in Arkhangelsk, 800km (497 miles) north of Moscow.

The Angara A5 is said to be much more environmentally friendly compared with Proton M, Russia’s heavy-lift rocket that has been in operation since the mid-1960s.

Moscow plans to use the rocket’s cargo capacities to deliver modules for a rival to the International Space Station (ISS) that it hopes to construct in the coming years.

Russia’s space programme has been hit by a number of high-profile setbacks in recent years.

Last month, its launch of a Soyuz spacecraft to the ISS was also delayed for two days. Three astronauts – from Russia, Belarus and the United States – were strapped in and ready for takeoff when a “voltage dip” triggered an automatic shutdown seconds before blastoff.

Russia’s first mission to the moon in almost 50 years failed last year when a lander crashed into the lunar surface.

Residents in North America look to the sky for a rare total solar eclipse | Space

A major golf tournament ground to a halt. Schools emptied of students. And thousands of people across North America turned their eyes to the sky to watch a rare celestial event.

On Monday, parts of Canada, Mexico and the United States were treated to a total solar eclipse, a phenomenon that will not arise for another two decades.

Full total eclipses are not uncommon, exactly: They happen once every 18 months or so, when the moon passes in front of the sun, blotting out its light.

But most solar eclipses happen where people cannot see them – in isolated stretches of the ocean, for instance. Monday’s total solar eclipse, therefore, offered a relatively rare chance for scientists and star-gazers alike to bask in the shadow cast by the moon.

The last time a total solar eclipse happened in North America was in 2017. The next opportunity for North Americans will come in 2044 and 2045, though other regions around the world will get their chance sooner.

In 2026, for instance, a total solar eclipse is expected to sweep south from the Arctic, appearing over Greenland, Iceland and parts of Spain.

Monday’s celestial spectacle began at about 11am local time (18:00 GMT) on the west coast of Mexico where the resort city of Mazatlan saw tourists crowd its beaches to watch.

The path of totality – the stretch of land where the total solar eclipse was visible – swept from northern Mexico to the central US state of Texas, where the prospect of severe weather forced the cancellation of a local eclipse festival.

The Texas Eclipse Festival in Burnet cited “risks of high winds, tornadic activity, large hail, and thunderstorms” as reasons for scrapping the four-day event.

The path of totality continued north through the southern US and into the northeast, tracing the border with Canada.

Schools in US states like New York, Ohio, Pennsylvania and Indiana cancelled classes and shuttered for the day, partly to let the students enjoy the event – and partly out of safety concerns.

The Pine-Richland School District in Pennsylvania, for instance, noted that the eclipse was slated to happen at the same time as classes would otherwise be dismissed.

“The potential is significant for students to be tempted to view it without proper safety precautions while exiting the school building or while getting off of the school bus,” the district wrote on its website.

Even outside of the path of totality, thousands of people gathered in open spaces to catch a glimpse as the moon seemingly took a bite out of the sun.

In Washington, DC, where the moon covered more than 87 percent of the surface of the sun by peak time at 3:20pm local time (19:20 GMT), people gathered on rooftops and at the National Mall to witness the eclipse.

Even at the height of the eclipse, it remained bright outside on the cloudless Monday.

Meanwhile, at the Masters Tournament in Augusta, Georgia – a major US golf championship – players briefly looked up from the green to contemplate an orb much bigger than a golf ball.

The last time the tournament had been interrupted by an eclipse was in 1940. Organisers passed out tournament-branded glasses specially designed for the eclipse, which was only partially visible from the southern state.

Speaking to the PGA Tour website, professional golfer Brian Harman winked at some of the conspiracy theories and folktales circulating about the eclipse.

“This is timed up pretty good,” he joked. “Get to watch the end of the world at Augusta National, right?”

Russian Soyuz rocket with 3 astronauts blasts off to ISS, days after glitch | Space News

The successful take off to the International Space Station follows an aborted launch on Thursday after a voltage drop in a power source.

A Russian Soyuz rocket carrying three astronauts to the International Space Station (ISS) blasted off on Saturday, two days after its launch was aborted at the last minute.

The spacecraft carrying NASA astronaut Tracy Dyson, Russian Oleg Novitsky and Marina Vasilevskaya of Belarus launched smoothly from the Russian-leased Baikonur launch facility in Kazakhstan.

The space capsule atop the rocket separated and went into orbit eight minutes after the launch. It then began a two-day, 34-orbit trip to the space station.

The three astronauts are to join the station’s crew, NASA astronauts Loral O’Hara, Matthew Dominick, Mike Barratt, and Jeanette Epps and Russians Oleg Kononenko, Nikolai Chub, and Alexander Grebenkin.

Novitsky, Vasilevskaya and O’Hara are to return to Earth on April 6.

The space station, which has served as a symbol of post-Cold War international cooperation, is now one of the last remaining areas of collaboration between Russia and the West amid tensions following Russia’s full-scale invasion of Ukraine.

NASA and its partners hope to continue operating the orbiting outpost until 2030.

Russia has continued to rely on modified versions of Soviet-designed rockets for commercial satellites, as well as crews and cargo to the space station.

Aborted launch

The launch had been planned for Thursday, but was halted by an automatic safety system about 20 seconds before the scheduled liftoff.

The head of the Russian space agency, Yuri Borisov, said a voltage drop in a power source triggered the launch to be aborted.

The aborted launch was a significant mishap for the Russian space programme.

It followed an October 2018 launch failure when a Soyuz rocket carrying NASA astronaut Nick Hague and Roscosmos’s Alexei Ovchinin to the ISS failed less than two minutes after the blastoff, sending their rescue capsule into a steep ride back to a safe landing.

Hague and Ovchinin had a brief period of weightlessness when the capsule separated from the malfunctioning Soyuz rocket at an altitude of about 50km (31 miles), then endured gravitational forces of six to seven times more than is felt on Earth as they came down at a sharper-than-normal angle.

The 2018 launch failure was the first such accident for Russia’s manned programme in more than three decades.

If the launch had gone as scheduled on Thursday, the journey would have been much shorter, requiring only two orbits. Docking is now expected at 15:10 GMT on Monday.

India’s ‘Whitey on the moon’ moment | Inequality

On August 23, 2023, India’s Chandrayaan-3 spacecraft successfully landed on the moon, making India the fourth country in the world, after the United States, the USSR and China, to achieve such a feat. It was a proud moment for a young, post-colonial nation just 75 years into her freedom. Tragically, it was also India’s very own “Whitey on the moon” moment.

In 1970, soon after the US became the first country in history to land on the moon, African-American jazz poet Gil Scott-Heron released his famous spoken word poem “Whitey on the moon”, criticising the Apollo space programme as a white man’s vanity project completed at great expense and with complete disregard for the deep poverty and exploitation being experienced by Black Americans at the time.

“The man jus’ upped my rent las’ night.

‘cause Whitey’s on the moon

No hot water, no toilets, no lights.

but Whitey’s on the moon

I wonder why he’s uppi’ me?

‘cause Whitey’s on the moon?

I was already payin’ ‘im fifty a week.

with Whitey on the moon”, sang Scott-Heron, accompanied by conga drums.

The poem quickly became a hit among Black Americans, who were angry that their country had invested in – and was shamelessly celebrating the completion of – an expensive space programme that did not involve or benefit their communities, while they were struggling with medical debt, high taxes, underemployment, urban decay, high rates of incarceration, and racial discrimination among other fundamental problems.

The parallels between the US society at the time of the Apollo mission described in this poem and modern-day India in the aftermath of its own landmark moon mission are difficult to ignore.

As Indian scientists – mostly upper caste, prosperous and secure in their place in the country – were celebrating the moon landing, millions of marginalised, disfranchised, impoverished Indians were suffering immensely.

Throughout the month-long journey of the Chandrayaan-3 spacecraft towards the moon, in the southeastern Indian state of Manipur, an ethnic cleansing effort was under way. Entire villages were burned to the ground, dozens were killed, and tens of thousands were left without homes.

Just before the beginning of the spacecraft’s journey, the government had gifted itself a brand new parliament building, which cost $120m to construct – a high price, especially at a time when, across the country, countless underprivileged Indians are struggling with hunger and unemployment. The controversial building was also inaugurated on a controversial date – the 140th birth anniversary of the father of Hindu nationalist ideology, VD Savarkar, who is a divisive figure due to his connection to the 1948 assassination of Mahatma Gandhi.

A six-time parliamentarian from the ruling  Bharatiya Janata Party (BJP) and the outgoing Wrestling Federation of India chief, Brij Bhushan Sharan Singh, who is accused of sexually abusing female wrestlers, was also present at the inauguration ceremony. Delhi police manhandled Indian wrestlers, many of them Olympians, who wanted to march to the parliament building to protest his actions.

Within six months of the eventful inauguration, the new parliament building was attacked, with two men entering the inner chambers, shouting slogans and setting off canisters of coloured gas. This was followed by an even more historic low, as 141 parliamentarians – all from opposition parties – were suspended for demanding a statement from the prime minister on the security breach. Without opposition, the Modi administration bulldozed three new pieces of legislation to India’s criminal justice system that allow the government to censor news content, imperil encrypted communication, shut down the internet, and intercept communications with minimal accountability.

Sadly, none of this is extraordinary in India today. The same nation that successfully sent a craft all the way to the moon has turned abuse and oppression of its most marginalised and underprivileged members into a casual pastime. Every day, Indian newspapers lay bare the bones of some broken minority. Headlines are depressing, scary. “Man rapes eight-year-old”; “Muslim lynched over beef”;  “Dalit man urinated upon, beaten”…

Minorities, sitting ducks with no power to protect themselves, endure abuse, humiliation and violence with no expectation of justice. They are left to stew in their own grief, the way raw mangoes are fermented in their own brine. Meanwhile, the rich and the privileged, the “whiteys” of India, celebrate the growing economy, the new temples, the impressive new parliament, and landmark journeys to the moon.

There is such little fraternity – genuine solidarity among citizens – in India.  It is baffling to me that we continue to call ourselves one nation, the world’s largest democracy.

The US-based non-profit Freedom House already downgraded India’s democracy from “free” to “partially free,” while the Sweden-based V-Dem Institute has deemed it an “electoral autocracy.” Democracy, from its long misuse, now exists only in our past. This is the only reasonable conclusion as every social contract underpinning law and order breaks down. Truth is, India is now a state of regulatory capture, and, as we enter another election year, the minorities of India have developed a collective wisdom unique to the oppressed: they know they are on their own.

So here we are. India made it to the moon, but Indian people are still poor, still hungry. Indian women are still unsafe. No scientific triumph can obscure the degradation of human life in our country. A journey to the moon cannot hide the ever-deepening inequality and seemingly endless injustices devastating minorities.

India’s always camera-friendly, attention-loving Prime Minister Narendra Modi who wasted no time basking in the glory of Indian scientists who took India to the moon, has yet to say a word on the violence in Manipur. Modi’s Home Minister Amit Shah immediately hailed the successful landing of Chandrayaan-3 – emphasising that it made India the first nation to “touch the South Pole of the moon”. However, he has yet to explain to the citizens why a BJP member had invited the two miscreants who attacked the parliament building. He has also not explained why sexual predators are welcomed to the Parliament and why he has not done a single press conference in the ten years he has been in office.

Just as the Apollo mission was a project for white America, Chandrayaan-3 was a project for educated, prosperous, upper-caste Indians.

With our many brilliant scientists and increasingly powerful technologies, I have no doubt India will soon put a man on the moon, and from there go on to Mars, Jupiter and the heavens beyond. None of it changes that we remain a country that has no money to feed the hungry, house the homeless, and tend to the sick – a country where, as “Whitey’s on the moon”, others have, as Scott-Heron said, “No hot water, no toilets, no lights.”

Japan successfully launches H3 rocket after back-to-back failures | Space News

The H3 flagship rocket is designed to replace the H-IIA after more than two decades in service.

Japan has successfully launched its next-generation rocket into orbit, the country’s space agency has announced, after two failed attempts cast a pall over Tokyo’s space ambitions.

The H3 had a “successful liftoff” at 9:22am Tokyo time (12:22 GMT) on Saturday and entered its planned orbit carrying a dummy satellite and two functioning microsatellites, the Japan Aerospace Exploration Agency (JAXA) said in a live broadcast.

Employees at the JAXA command centre cheered and hugged each other during the broadcast as the rocket reached its trajectory and released its first payload.

The H3’s microsatellites are expected to assist with disaster prevention efforts and monitor the operation conditions of factories.

JAXA is scheduled to hold a press conference on the launch later on Saturday.

The H3, billed as Japan’s flexible and cost-effective flagship rocket, was designed to replace the H-IIA, which has been in service since 2001.

The H3, which was developed with Mitsubishi Heavy Industries, is designed to carry a 6.5 metric tonne payload into space for as little as five billion yen ($33m) per launch, about half the cost of its predecessor.

JAXA hopes that the H3’s lower costs and greater payload capacity will attract global clients for missions, such as delivering supplies to the International Space Station and supporting the US-led Artemis moon exploration programme.

Tokyo has said it intends to launch about 20 satellites and probes with H3 rockets by 2030.

The H3’s successful launch follows back-to-back failures last year, including a botched launch in March that ended with ground control utilising the rocket’s self-destruct function shortly after blast-off after the second-stage engine failed to ignite.

JAXA identified three possible electrical faults in a subsequent review of the launch, but could not determine the direct cause of the failure, which caused significant delays to its space plans.

Japan last month successfully landed its unmanned probe SLIM on the moon, becoming the fifth country to place a craft on the lunar surface.

US says Russia developing ‘troubling’ space-based anti-satellite weapon | Weapons News

White House says weapon is not yet operational and poses no immediate threat but puts astronauts at risk.

Russia is developing a space-based anti-satellite weapon that is “troubling” but poses no immediate threat, the White House has said.

National security spokesman John Kirby said US intelligence officials had information that Russia had developed the technology but that the weapon was not currently operational.

He said US officials were analysing the information they had and consulting with allies in Europe.

“This is not an active capability that’s been deployed, and though Russia’s pursuit of this particular capability is troubling, there is no immediate threat to anyone’s safety,” Kirby said on Thursday.

He confirmed the weapon was “space-based” but would not comment on reports in US media that it was either nuclear-capable or nuclear-powered.

“We’re not talking about a weapon that can be used to attack human beings or cause physical destruction here on Earth,” he said.

Moscow downplayed the US claims, describing them as a “malicious fabrication” that were a White House ploy to try and secure the passage of a multibillion-dollar Ukrainian aid package through a resistant Republican-led House of Representatives.

“It’s obvious that Washington is trying to force Congress to vote on the aid bill by hook or by crook,” Kremlin spokesperson Dmitry Peskov said in remarks carried by Russian news agencies. “Let’s see what ruse the White House will use.”

The US and the United Kingdom previously alleged Russia had tested a space weapon in 2020. On that occasion, Moscow said the claims were “propaganda“.

Kirby said the latest weapon could pose a lethal risk to astronauts in low orbit, along with potentially disrupting vital military and civilian satellites.

It would also breach the 1967 Outer Space Treaty, which prohibits the deployment of “nuclear weapons or any other kinds of weapons of mass destruction” into orbit or to “station weapons in outer space in any other manner”. More than 130 countries have signed the agreement, including Russia and the US.

Experts said the US does not have the capability to counter such a weapon.

US President Joe Biden had been kept informed and had requested direct diplomatic engagement with Moscow over the weapon.

The threat came to light after Mike Turner, chairman of the House of Representatives Intelligence Committee, issued an unusual warning about a “serious national security threat” and called on Biden to “declassify all information relating to this threat”.

On Thursday, another Republican House member, Andy Ogles, urged House Speaker Mike Johnson to investigate the impact Turner’s action may have had on foreign and domestic policy, asking whether he should remain chairman.

White House national security adviser Jake Sullivan also briefed lawmakers.

After the meeting, Turner said Sullivan had discussed the administration’s options in addressing the potential threat.

“I think the bottom line is that we all came away with a very strong impression that the administration is taking this very seriously and that the administration has a plan in place,” he said. “We look forward to supporting them as they go to implement it.”

Johnson, who also attended the briefing, said it was  “informative” and that the White House will remain in close contact with lawmakers about the matter.

“It is a very serious matter. It does involve Russia,” Johnson told reporters, adding that the administration and Congress would stay in close contact. “And it will be dealt with.”

The US sees Russia and China as its biggest nation-state competitors and says both are developing a range of new weapons systems, including nuclear, cyber and space capabilities.
