Solar Orbiter spacecraft makes its 1st flyby of the sun

Solar Orbiter, a joint mission by NASA and the European Space Agency, has hit its first big milestone of its sun-watching mission — and the spacecraft will soon have pictures to prove it.

The probe is designed to give scientists a view of our sun unlike any they’ve ever seen before. That’s because Solar Orbiter carries technology to gather images of our star, and its trajectory will allow it to study the poles of the sun, which never align toward Earth. And the science starts now, with the spacecraft executing its first flyby of the sun, or perihelion, today (June 15). The orbital manoeuvre brought the probe to about half the distance between the Earth and the sun, or about 48 million miles (77 million kilometres).

Solar Orbiter launched in February and carries a total of 10 instruments: six telescopes and four instruments designed to study the spacecraft’s immediate surroundings. Mission team members have been powering up and checking each instrument since shortly after the spacecraft’s launch, but this week’s data-gathering will be a new test for the probe. According to the statement, the spacecraft’s first imaging campaign will occur in the week following this close approach, or perihelion. It will take the spacecraft another week to beam those images back to Earth given its current distance from home, and the mission team expects to publish the resulting images in mid-July.

Kathy Lueders Selected to Lead NASA’s Human Spaceflight Office

NASA Administrator Jim Bridenstine has selected Commercial Crew Program Manager Kathy Lueders to be the agency’s next associate administrator of the Human Exploration and Operations (HEO) Mission Directorate. Since 2014, Lueders has directed NASA’s efforts to send astronauts to space on private spacecraft, which culminated in the successful launch of Demo-2 from the Kennedy Space Centre in Florida on May 30. “Kathy gives us the extraordinary experience and passion we need to continue to move forward with Artemis and our goal of landing the first woman and the next man on the Moon by 2024,” said Bridenstine. “She has a deep interest in developing commercial markets in space, dating back to her initial work on the space shuttle program. From Commercial Cargo and now Commercial Crew, she has safely and successfully helped push to expand our nation’s industrial base. Kathy’s the right person to extend the space economy to the lunar vicinity and achieve the ambitious goals we’ve been given.” The appointment takes effect immediately. Steve Stich is named Commercial Crew Program Manager, and Ken Bowersox returns to his role as HEO deputy associate administrator.

Lueders began her NASA career in 1992 at the White Sands Test Facility in New Mexico where she was the Shuttle Orbital Manoeuvring System and Reaction Control Systems Depot manager. She later moved to the International Space Station Program and served as transportation integration manager, where she led commercial cargo resupply services to the space station. She also was responsible for NASA oversight of international partner spacecraft visiting the space station, including the European Space Agency’s Automated Transfer Vehicle, the Japan Aerospace Exploration Agency’s H-II Transfer Vehicle, and the Russian space agency Roscosmos’ Soyuz and Progress spacecraft. She went to Kennedy as acting Commercial Crew Program Manager in 2013 and was selected as the head of the office in 2014.

Virtual reality will be a big part of Boeing’s Starliner astronaut training

Astronauts will get some next-gen training before they ride Boeing’s next-gen spacecraft, with the virtual reality gear due to ship to Florida in the next couple of weeks. Crewmembers preparing to fly on Boeing’s CST-100 Starliner capsule will train using virtual reality (VR) headsets provided by Finland-based Varjo, both companies announced recently. Varjo’s VR-2 devices will allow astronauts to simulate, in high resolution and with high fidelity, every aspect of a Starliner mission to the International Space Station (ISS), Varjo and Boeing representatives said.

“We are proud to be delivering the technology that is pushing industrial training applications to their furthest reaches — even to space,” Varjo co-founder and CEO Niko Eiden said in a statement. “With our devices, astronauts can see and virtually interact with the switches and control panels inside their Starliner capsule and read the real-time data on their crew displays,” Eiden said. “Advancements like this have the potential to transform the way any pilot is trained.”

Boeing has been developing Starliner with funding from NASA’s Commercial Crew Program, most notably a $4.2 billion contract signed in 2014 that also covers six operational crewed missions to and from the ISS. SpaceX holds a similar deal, which Elon Musk’s company will fulfil with its Crew Dragon capsule. SpaceX just launched its first crewed mission, sending NASA astronauts Bob Behnken and Doug Hurley to the ISS on a test flight called Demo-2. Starliner should follow suit relatively soon; Boeing plans to launch its version of Demo-2, called Crew Flight Test (CFT), early next year.

NASA delays launch of Mars rover Perseverance to July 20

NASA’s next Mars rover won’t get off the ground on July 17 after all.

The launch of the car-size Perseverance rover from Florida’s Cape Canaveral Air Force Station has been pushed to July 20 because “additional time was needed for the team to repair an issue with the ground system equipment,” NASA officials said in an update today (June 11). It’s a 3-day delay, but there’s still a fair bit of wiggle room in Perseverance’s schedule as the rover’s launch window extends through August 11. But that end date is a hard deadline, marking the end of a lift-off opportunity that comes around only once every 26 months. Mars and Earth aren’t properly aligned for interplanetary missions very often.

Whenever Perseverance lifts off during the coming window, the six-wheeled robot will land inside Mars’ 28-mile-wide (45 kilometres) Jezero Crater on February 18, 2021 and perform many tasks including hunting for signs of ancient life in Jezero, characterising the area’s geology as well as collecting and caching dozens of Mars samples for future return to Earth. One of the rover’s instruments will generate oxygen from Mars’ carbon dioxide-dominated atmosphere. This tech, once scaled up, could aid human exploration of the Red Planet, NASA officials have said. A small helicopter scout, named Ingenuity, will be deployed to make some short flights in the thin Martian air, and if it performs well, aerial exploration could play a large role in future Mars missions.

Titan is drifting away from Saturn 100 times faster than scientists’ predictions

The Saturnian moon’s orbit around the planet is getting farther away faster than previously predicted: 100 times faster than scientists expected. According to a new study, Saturn’s largest moon Titan was “born” fairly close to the planet, but over the course of 4.5 billion years, it has migrated out to where it orbits currently, approximately 746,000 miles (1.2 million kilometres) away from the planet. “Most prior work had predicted that moons like Titan or Jupiter’s moon Callisto were formed at an orbital distance similar to where we see them now,” Jim Fuller, assistant professor of theoretical astrophysics at Caltech and co-author on the new study. “This implies that the Saturnian moon system, and potentially its rings, have formed and evolved more dynamically than previously believed.”

Moons exert a small gravitational pull on the planets they orbit, tugging at the planet. This gravitational interaction is what causes tides in the oceans here on Earth. On our planet, friction inside of Earth from this tugging creates heat, which alters the planet’s gravitational field. This gradually pushes the moon farther away from Earth, about 1.5 inches (3.8 centimetres) every year. Titan tugs on Saturn in a similar way, but the friction inside of Saturn is thought to be weaker than here on Earth because of the planet’s gaseous composition (compared to Earth’s rocky nature). Previous research has suggested that the moon should be moving away from Saturn at just 0.04 inches (0.1 cm) per year. But this new work suggests that Titan is actually moving away from its planet at a whopping 4.3 inches (11 cm) every year.

NASA sun observatory spies Comet Atlas in the solar wind, and Mercury too!

You’ll need a minute to take it all in, there’s a lot going on in this stunning view of the inner solar system, including a comet, Mercury and some solar weather. This view was captured by NASA’s Solar Terrestrial Relations Observatory A, or STEREO-A. The spacecraft launched in 2006 with its now-silent twin to study the sun, in particular from angles we can’t see from Earth.

The pale haze gusting in from the left of the image is the solar wind, the charged particles that constantly stream out of the sun and across the solar system, creating the bubble Earth and its neighbours move through. And of course there are countless stars, some that appear to be standing on bright stalks (the streaks are just flukes in the image). Near the end of the loop, Mercury crosses into view from the left side of the image, moving across the background of stars, according to a NASA statement.

And STEREO-A’s location was a perfect vantage point to catch sight of a comet that threw sky watchers into a frenzy this year, dubbed Comet ATLAS. Astronomers first spotted the object at the end of December 2019, and soon identified it as a comet new to Earth’s neighbourhood. This animation compiles images taken between May 25 and June 1 2020.

NASA issues contract to Northrop Grumman for Gateway module

NASA announced on June 5 that it awarded a contract to Northrop Grumman to begin work on a habitation module for the lunar Gateway, nearly a year after the agency announced its intent to sole-source that module to the company.

NASA said it issued a contract to Northrop Grumman valued at $187 million for the Habitation and Logistics Outpost (HALO) module, which will serve as an initial habitat for crews visiting the lunar Gateway. The module, described by NASA as the size of a small studio apartment, will be able to support short stays by crews arriving on Orion spacecraft.

The contract does not cover all the work needed for HALO. Instead, the award announced June 5 funds design of the module through a preliminary design review late this year. The contract also allows Northrop Grumman to issue subcontracts for hardware with long lead times. A contract modification will come later to fund full development and testing of HALO.

The only surprise about the contract is the time it took NASA to formally issue it. In a July 2019 procurement filing, NASA announced its intent to issue a sole-source award to Northrop Grumman after concluding that the company was the only one who would have a module ready to support the agency’s plans to return humans to the moon by 2024.

Northrop’s module is based on its Cygnus spacecraft used to transport cargo to the International Space Station. “The success of our Cygnus spacecraft and its active production line helps to enable Northrop Grumman to deliver the HALO module,” said Steve Krein, vice president of civil and commercial satellites at Northrop Grumman, in a company statement.

Northrop, though, will make significant modifications to the Cygnus design for HALO, such as installing several docking ports to accommodate Orion spacecraft or other Gateway elements. It will also have new command and control systems and an enhanced life support system to support visiting crews.

“This contract award is another significant milestone in our plan to build robust and sustainable lunar operations,” said NASA Administrator Jim Bridenstine in an agency statement. “The Gateway is a key component of NASA’s long-term Artemis architecture and the HALO capability furthers our plans for human exploration at the moon in preparation for future human missions to Mars.”

Colonizing Mars may require humanity to tweak its DNA

Genetic engineering may be a big part of our future on Mars. If humanity is ever going to settle down on Mars, we may need to become a little less human.

Crewed missions to Mars, which NASA wants to start flying in the 2030s, will be tough on astronauts, exposing them to high radiation loads, bone-wasting microgravity and other hazards for several years at a time. But these pioneers should still be able to make it back to Earth in relatively good nick, agency officials have said.

It might be a different story for those who choose not to come home, however. If we want to stay safe and healthy while living permanently on Mars, or any other world beyond our home planet, we may need to make some tweaks to our species’ basic blueprint, experts say.

Genetic engineering and other advanced technologies “may need to come into play if people want to live and work and thrive, and establish their family, and stay on Mars,” Kennda Lynch, an astrobiologist and geomicrobiologist at the Lunar and Planetary Institute in Houston, said on May 12 during a webinar hosted by the New York Academy of Sciences called “Alienating Mars: Challenges of Space Colonization.”

Martian moon’s orbit suggests the Red Planet had a ring

A cycle of moon formation could explain the slightly tilted orbit of Mars’ moon Deimos.

Mars has two moons circling the planet, called Phobos and Deimos. For many years, scientists supposed that both of these moons were captured asteroids, or space rocks. But new research shows the orbit of Deimos would not make that possible.

Deimos is very slightly tilted to the Martian equator, by only two degrees. Initially, the difference was so small that many scientists overlooked the matter.

“The fact that Deimos’ orbit is not exactly in plane with Mars’ equator was considered unimportant, and nobody cared to try to explain it,” study lead author Matija Cuk, a research scientist at the SETI Institute, said in a statement. “But once we had a big new idea and we looked at it with new eyes, Deimos’ orbital tilt revealed its big secret.”

The secret came from looking at the motions of Phobos, which orbits closer to the Martian surface and is slowly spiralling into the planet. Eventually, Phobos will drop so close to Mars that the gravity of the much larger planet will pull the moon into pieces — forming a ring.

Study co-authors David Minton, a professor at Purdue University, and Andrew Hesselbrock, who was his graduate student at the time of the research, suggest that Phobos’ future is not a one-off event. Instead, after the moon is pulled apart, eventually the pieces will reform into another moon. This not only will happen to Phobos, but has happened already other times in the Martian past.

This breaking up and reforming of moons would in turn explain how Deimos’ orbital tilt happened.

Demo-2 astronauts get to work on ISS

After making history on the first crewed flight of an orbital spacecraft launched from the United States in nearly nine years, two NASA astronauts are settling in on the International Space Station. Astronauts Bob Behnken and Doug Hurley arrived at the ISS May 31, 19 hours after the Crew Dragon spacecraft they were on launched

How close can you get to a black hole?

The event horizon of a black hole is the invisible line-in-the-sand across which you can never return. Once anything passes through the event horizon, even light itself, it can no longer return to the universe. The black hole’s gravity is just too strong within that region.

Streams of gas fall to their dooms, plunging into black holes, locked away from the universe forever. In their final moments, these gassy shreds send out one last flare of light, some of the brightest emissions in the universe.

In a new study, physicists looked at specific features of that light to figure out the closest you can get to a black hole without having to work hard to prevent disaster — a threshold called the innermost stable circular orbit or ISCO.

This boundary, ISCO, is a firm prediction of Einstein’s general theory of relativity, the same theory that predicts the existence of black holes in the first place. Despite the success of general relativity in predicting and explaining phenomena across the universe, and our sure knowledge that black holes are real, we’ve never been able to verify the existence of the ISCO and whether it conforms to the predictions of general relativity.

But the gas that falls to its doom may provide a way for us to verify that existence.

Lift-off! SpaceX launches 1st astronauts for NASA on historic test flight

SpaceX launched astronauts for the first time ever today, making history and opening a new age of commercial spaceflight. A shiny white Falcon 9 rocket lifted off from historic Pad 39A at NASA’s Kennedy Space Center on May 30 at 3:22 p.m. EDT (1922 GMT), carrying SpaceX’s Crew Dragon capsule into orbit. The launch kicked off SpaceX’s landmark Demo-2 mission, sending NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS). Demo-2 marks the return of orbital human spaceflight to U.S. soil after a nearly decade-long absence, and it signals the beginning of a new era in space exploration — one led by commercial companies.

Following the successful launch, SpaceX’s Crew Dragon capsule slid into a dock at the International Space Station on Sunday May 31, concluding a historic 19-hour voyage to for its veteran NASA crew. The arrival marked a major feat: the first docking of a crewed U.S. spacecraft at the station since NASA’s shuttle fleet retired in 2011. It’s also the first docking of a commercial spacecraft carrying humans, in this case astronauts Bob Behnken and Doug Hurley.

The Crew Dragon docked itself at the station 10:16 a.m. EDT (14216 GMT) as both spacecraft sailed 262 miles (422 kilometers) above the border of China and Mongolia. While today’s docking was completely automated, Hurley did take manual control of the Crew Dragon spacecraft (which he and Behnken have christened Endeavour) during a final test. The ship handled just like the simulator, he said. After the Crew Dragon docking, Behnken and Hurley performed a series of leak checks to make sure their spacecraft was safely secured to the space station. But at 1:02 p.m. EDT (1702 GMT), the festivities began. That’s when the crew opened the hatch of their spacecraft to join NASA astronaut Chris Cassidy and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner, who have been in orbit since April.

Rocket Lab to resume launches from its New Zealand launch site in June

Rocket Lab will resume launches of its Electron small launch vehicle in June as the effects of the coronavirus pandemic ease at its New Zealand launch site.

The company announced May 28 it has rescheduled an Electron launch for June 11 local time from its launch site on New Zealand’s Mahia Peninsula. That launch was previously scheduled for March 30 but postponed because of a lockdown imposed by the New Zealand government in response to the pandemic.

The announcement of the new launch date comes as New Zealand scales back its response to the pandemic. The country stepped down to Alert Level 2 of its response plan on May 29 (local time), allowing larger gatherings of people, as the country has reported only a handful of new cases of COVID-19 since the middle of the month. Rocket Lab said in its statement about the launch that it will continue to use “enhanced health and safety processes” for employees working on this launch, including physical distancing, split shifts and enhanced cleaning.

The launch, called “Don’t Stop Me Now” by the company, has the same set of payloads as what the company originally announced in March.

SpaceX delays 1st astronaut launch for NASA due to bad weather

Mother Nature didn’t cooperate today. Elon Musk’s company was scheduled to launch its first-ever crewed mission, a test flight to the International Space Station (ISS) called Demo-2, this afternoon May 27 4.30 pm EDT (May 28 6.30 am AEST) from NASA’s Kennedy Space Center in Florida. But bad weather has nixed that plan, pushing the lift-off back to Saturday May 30 at the earliest, NASA and SpaceX officials announced today.

Demo-2 has an instantaneous launch window: the capsule must launch at a specific time, when the space station is at a certain spot in its orbital path. The next attempt will be on Saturday at 3:22 pm EDT (1922 GMT). For those in Australia the launch will be on Sunday at 5.22 am AEST.

If that doesn’t work out, SpaceX could try again on Sunday (May 31) at 3.00 pm EDT (1900 GMT). For those in Australia this would be Monday June 1 at 5.00 am AEST.

NASA and SpaceX to launch astronauts into orbit this week on Crew Dragon spacecraft: the countdown is on!

This week, astronauts will take off from American soil for the first time since 2011, riding aboard a SpaceX capsule in a historic test flight to the International Space Station.

On Wednesday (May 27) at 4:33 p.m. EDT (2033 GMT), veteran NASA astronauts Bob Behnken and Doug Hurley will launch as co-commanders on SpaceX’s Crew Dragon vehicle, which will lift off on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. The mission, known as Demo-2, will fly the astronauts to the International Space Station. They are scheduled to arrive at the space station on May 28 and could stay in space anywhere from one to four months.

Demo-2 will be the first crewed launch to orbit from American soil since NASA’s shuttle program ended in 2011. In fact, Hurley was on the crew for both that final shuttle mission (STS-135) and the upcoming mission. The astronauts arrived at Kennedy Space Center on May 20, a week ahead of the launch, and have been preparing diligently for their ride to space. “We are on the cusp of launching American astronauts on American rockets from American soil yet again,” NASA Administrator Jim Bridenstine said May 20 after Hurley and Behnken arrived at Kennedy. “You really are a bright light for all of America right now. Thank you so much for all you’ve done and all you’re about to do.”
