Mysterious gamma-ray ‘heartbeat’ detected from cosmic gas cloud

A cosmic gas cloud has a mysterious gamma-ray “heartbeat” that appears to be in sync with a neighbouring black hole. Using data from the Arecibo Observatory in Puerto Rico and NASA’s Fermi Gamma-ray Space Telescope, an international team of researchers found the “heartbeat” in a cosmic gas cloud in the constellation Aquila, the eagle. The cloud “beats” in rhythm with a miniature black hole located roughly 100 light-years away, suggesting the objects are connected in some way, according to a statement from the DESY national research center in Germany.

The black hole is part of a micro quasar system known as SS 433, which includes a giant star that is approximately 30 times the mass of the sun. A micro quasar is just a small quasar, the brightest type of object in the universe, which consists of a large black hole that emits extraordinary amounts of light as it gobbles up its stellar neighbours. As the two objects in SS 433 orbit each other, the black hole pulls in matter from the giant star, creating an accretion disk around the black hole.

Their findings, published Aug. 17 in the journal Nature Astronomy, suggest the gas cloud’s emission, or “heartbeat,” is powered by the micro quasar. However, the two objects are located relatively far apart, at a distance of about 100 light-years. Therefore, further observations are needed to fully understand how the black hole powers the heartbeat in the gas cloud.

Japan’s final HTV cargo spacecraft leaves space station for fiery end

Japan’s “white stork” has taken flight from the International Space Station for the last time. The Japan Aerospace Exploration Agency’s (JAXA) ninth H-II Transfer Vehicle, or HTV-9, was released from its temporary perch at the end of the space station’s robotic arm on Tuesday (Aug. 18) at 1:36 p.m. EDT (1736 GMT). The uncrewed cargo vehicle, which JAXA nicknamed the “Kounotori,” or “white stork,” will spend two more days in orbit before flight controllers in Tsukuba, Japan, command an engine burn that it will send the spacecraft plunging back into Earth’s atmosphere. Loaded with about 7,400 lbs. (3,400 kilograms) of used equipment and trash from the space station, the HTV will meet its fiery end, succumbing to the heat of re-entry and burning up over the Pacific Ocean.

The de-orbit will mark the end of 11 years of HTV missions. First launched on Sept. 10, 2009, atop Mitsubishi Heavy Industries’ first H-IIB rocket from the Tanegashima Space Center in southern Japan, the barrel-shaped HTV was Japan’s first spacecraft to service a space station and the first uncrewed vehicle to be berthed on the U.S. segment of the International Space Station (ISS). The 33-foot (10-meter) long and 14-foot (4.4-meter) wide, solar-powered spacecraft was also the first capsule to carry both pressurized and unpressurized cargo. “Over the past 11 years, the H-II Transfer Vehicle Kounotori has delivered over 40 tons of cargo, research, hardware and equipment to the International Space Station,” Joel Montalbano, NASA’s ISS program manager, said in a statement during NASA TV’s broadcast of the departure. “I want to congratulate Japan on the HTV missions.”

ESA sets stage for three-way competition to build next-generation Galileo constellation

The European Space Agency is preparing to select two companies to build the second generation of Galileo navigation satellites under contracts to be signed in early 2021.

The ESA-led competition, arranged on behalf of the European Commission, pits rising German manufacturer OHB against European heavyweights Thales Alenia Space and Airbus Defense and Space, Paul Verhoef, ESA director of navigation, told SpaceNews by email. “The intention is to retain two suppliers in a dual-source mode providing these satellites,” he said.

ESA will initially order two satellites apiece from the selected providers. Follow-on contracts will cover the next 12 satellites in a constellation that will eventually consist of 24 active satellites and up to six spares.

OHB, once a novice in satellite manufacturing, now finds itself in the role of the incumbent, having built 22 of the 26 Galileo satellites in orbit. Airbus and Thales Alenia Space Italy built the first four satellites, which were used to validate the concept for the larger constellation.

NASA powers up Ingenuity Mars helicopter in space for the 1st time

NASA’s Mars helicopter, named Ingenuity, successfully powered up for the first time in space last week and Ingenuity’s electronics are in good shape. Ingenuity is the first helicopter designed to fly on another planet. It is currently travelling to the Red Planet aboard NASA’s Mars 2020 Perseverance rover, which launched on July 30. On Aug. 7, the helicopter’s six lithium-ion batteries were powered up and charged for the first time in space. The 4-lb. (1.8 kilograms) Ingenuity, which is currently stowed beneath Perseverance’s belly, receives its charge from the rover’s power supply, according to a Thursday (Aug. 13) statement from NASA.

“This was a big milestone, as it was our first opportunity to turn on Ingenuity and give its electronics a ‘test drive’ since we launched on July 30,” Tim Canham, the operations lead for Mars Helicopter at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, said in the statement. “Since everything went by the book, we’ll perform the same activity about every two weeks to maintain an acceptable state of charge.” Perseverance is scheduled to land on Mars on Feb. 18, 2021. At some point after that, Ingenuity will detach from the rover, descend to the Red Planet surface and take a few pioneering test flights. (After deployment on Mars, the helicopter’s batteries will be charged by its own solar panel.) If the experimental test flights go according to plan, Ingenuity will prove that robotic flight is possible on Mars, opening the door for extensive aerial exploration on future missions.

The bizarre dimming of bright star Betelgeuse caused by giant stellar eruption

Betelgeuse’s odd recent dimming was caused by a huge cloud of material that the supergiant star blasted into space, a new study suggests. The bright star Betelgeuse, which forms the shoulder of the constellation Orion (The Hunter), is about 11 times more massive than the sun but 900 times more voluminous. That bloated condition shows that Betelgeuse is near death, which will come in the form of a violent supernova explosion. In the fall of 2019, Betelgeuse began dimming significantly, losing about two-thirds of its brightness by February. This dramatic dip spurred speculation that the star’s demise may have been imminent — perhaps just weeks away. (From our perspective, anyway; Betelgeuse lies about 500 light-years from Earth, so everything we’re seeing with the star today happened centuries ago.)

But the dramatic sky show didn’t happen: Betelgeuse powered through the dimming episode and returned to its normal brightness by May of this year. The recovery sparked a new round of speculation, this time about the dimming’s cause. Some scientists attributed the doldrums to a light-blocking dust cloud, for example, whereas others said big star spots on Betelgeuse’s surface were likely to blame. A new study bolsters the dust hypothesis, but adds a twist — Betelgeuse itself apparently coughed up the cloud.

Meet ‘Tenacity’: 1st Dream Chaser space plane gets a name

The first orbital Dream Chaser space plane recently got its wings, and a name. Tenacity is scheduled to launch for the first time in late 2021. Dream Chaser, which is built by Colorado-based company Sierra Nevada Corp., is the world’s only non-capsule private orbital spacecraft. The winged vehicle will launch vertically atop a rocket but end its missions with runway landings, like NASA’s now-retired space shuttle orbiters used to do.

This spring, the company unboxed the wings for the first operational Dream Chaser vehicle, bringing it one step closer to delivering supplies and science to and from the International Space Station. Tenacity is scheduled to launch for the first time in late 2021, aboard a United Launch Alliance Vulcan Centaur rocket from NASA’s Kennedy Space Center in Florida. Once it’s up and running, the space plane will carry cargo to and from the space station for NASA. Dream Chaser’s runway landings will allow efficient retrieval and removal of scientific gear coming back to Earth, which will also enjoy a relatively smooth ride down to the ground, Sierra Nevada representatives said.

Dream Chaser was originally designed to carry people, and Sierra Nevada won several rounds of funding from NASA’s Commercial Crew Program to develop the vehicle. However, the company lost out to Boeing and SpaceX when NASA awarded astronaut-ferrying contracts in 2014. But in 2016, NASA selected the space plane for its Commercial Resupply Services 2 contract, awarding Sierra Nevada a contract to fly six uncrewed cargo missions to the space station by 2024.

Sierra Nevada needed to change out only about 20% of Dream Chaser’s module to transition from a passenger vehicle to a cargo plane, said Anna Hare, a company communications representative. Sierra Nevada therefore hasn’t ruled out a crew-carrying future for the space plane at some point. “To go back to a crew ship wouldn’t be so hard,” Hare said.

Rocket Lab ready to attempt Electron booster recovery

Rocket Lab says it’s on track to test recovering an Electron booster later this year as it also improves the payload performance of the small launch vehicle. Rocket Lab announced last week it completed drop tests of a dummy Electron first stage at its New Zealand launch site, demonstrating that its parachute would deploy as expected and slow the booster after re-entry. “We basically simulated the highest load case, where we drop a fully weighted dummy stage out of the sky and accelerate it to the highest load point and then pop the canopy,” Peter Beck, chief executive of Rocket Lab, said during a company webcast Aug. 5 held during the 34th Annual Small Satellite Conference. Beck said that was the “final test” of the overall recovery system for the Electron first stage, part of an effort the company announced one year earlier to recover and reuse the boosters. Rocket Lab tested on earlier launches the ability of the stage to perform a controlled re-entry, as well as using a helicopter to catch the stage as it descends under a parachute.

With the tests complete, Beck said Rocket Lab intends to make its first effort to recover a first stage on an upcoming launch, known as Flight 17 and expected to take place later this year. “That is really the final signoff before we’re ready to go fly Flight 17,” he said. “Flight 17 is sitting in the hangar.”

Beck said Rocket Lab won’t attempt to catch the stage in mid-air on the Flight 17 mission, focusing instead on simply recovering the booster from the ocean. “We’ll fish it out of the ocean, bring it back, put it in the factory and then we’ll really see what we’ve got,” he said. “That will determine how much work we have ahead of us.” Rocket Lab said last year it decided to pursue reusability in order to increase its launch rate without having to make major investments in increased booster production.

This giant crater on Ceres with bright spots may be the most fascinating place in the solar system

For a few months in 2018, as NASA’s Dawn spacecraft used up its last drops of fuel, it gave scientists an incredibly detailed look at one of the strangest places in the solar system: Occator Crater. That’s the name of a massive impact site on the dwarf planet Ceres, tucked away in the asteroid belt. In the mission’s last months, Dawn flew just 22 miles (35 kilometres) above the dwarf planet’s surface and focused its energies on Occator Crater. Earlier observations from the mission had suggested that some sort of geological activity was bringing saltwater to the surface, and scientists wanted a closer look.

Now, initial analysis of those final months of science suggest that Ceres may have been active much more recently than scientists had dared to imagine, according to an article summarizing seven different research papers published on August 10 in the journals Nature Communications, Nature Geoscience and Nature Astronomy. “Dawn accomplished far more than we hoped when it embarked on its extraordinary extra-terrestrial expedition,” Mission Director Marc Rayman of NASA’s Jet Propulsion Laboratory in California said in a NASA statement. “These exciting new discoveries from the end of its long and productive mission are a wonderful tribute to this remarkable interplanetary explorer.”

The new research papers focus on a host of different intriguing findings about Occator Crater, which is about 22 million years old and about 57 miles across (92 km), as well as about Ceres more generally. Although Dawn’s final months revolutionized scientists’ view of the dwarf planet and its large crater, the new research doesn’t satisfy curiosity about this ocean world asteroid and may lay the groundwork for a new mission to Ceres, according to an overview paper released with the new findings.

Pentagon picks SpaceX and United Launch Alliance to remain its primary launch providers

The U.S. Department of the Air Force announced that incumbents United Launch Alliance (ULA) and SpaceX have been selected to receive five-year contracts totalling $653 million to launch national security satellites for the U.S. military and intelligence agencies. The companies beat Blue Origin and Northrop Grumman in the four-way competition known as the National Security Space Launch Phase 2 Launch Service Procurement.

Between 2022 and 2027 SpaceX and ULA will collectively fly as many as 34 missions for the Department of Defense and the National Reconnaissance Office under the firm-fixed-price, indefinite-delivery contracts. In Phase 2 ULA will get 60 percent of the missions, and SpaceX will get 40 percent. The Air Force will assign specific rockets on a yearly basis depending on the required missions. “Maintaining a competitive launch market, servicing both government and commercial customers, is how we encourage continued innovation on assured access to space,” Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics, told reporters.

Roper said the Phase 2 awards mark a pivotal point in the transition of the national security launch program to take advantage of commercial innovation and private investments in launch vehicles. “Today’s awards mark a new epoch of space launch that will finally transition the Department of Defense off Russian RD-180 engines,” he said. The shift to new launch vehicles also is compelled by a legislative mandate to end the Pentagon’s reliance on United Launch Alliance’s Atlas 5 rocket which has the Russian RD-180 as its main engine. By law, Department of Defense will not be allowed to buy Atlas 5 launches after Dec. 31, 2022.

Signs of ‘missing’ neutron star found in heart of supernova

Evidence of a neutron star hidden deep inside Supernova 1987A is helping astronomers solve a 33-year-old mystery surrounding one of the brightest star explosions ever observed. On Feb. 23, 1987, astronomers witnessed an incredibly bright stellar explosion, also known as a supernova. Using the Atacama Large Millimetre/submillimetre Array (ALMA), researchers believe they have found that explosion’s remnants, a super dense corpse called a neutron star, hiding within the dust of the supernova. High-resolution ALMA images revealed what researchers described as a hot “blob” that is brighter than its surroundings and located at the supernova’s dusty core. If confirmed, this neutron star would be the youngest known to date, according to a statement. “We were very surprised to see this warm blob made by a thick cloud of dust in the supernova remnant,” Mikako Matsuura, an astronomer at Cardiff University and one of the researchers who spotted the blob, said in the statement. “There has to be something in the cloud that has heated up the dust and which makes it shine. That’s why we suggested that there is a neutron star hiding inside the dust cloud.”

Their findings were published in November 2019, in The Astrophysical Journal. At the time, however, the researchers could not definitively say what the glowing blob was, as it was believed to be too bright to be a neutron star. A new paper offers an explanation for that brightness in a neutron star: the glowing blob is consistent with thermal emission from a very young neutron star that is still really hot from the supernova explosion, according to the statement. The researchers estimate the temperature of the 15.5 mile (25 kilometre) wide neutron star is approximately 9 million degrees Fahrenheit (5 million degrees Celsius), which provides enough energy to explain the blob’s brightness. The study also suggests the neutron star is located off-centre, as researchers expect, due to the powerful stellar blast.

SpaceX’s Starship SN5 prototype soars on 1st test flight!

SpaceX just flew a full-size prototype of its Starship Mars-colonizing spacecraft for the first time ever. The short hop could end up being a big leap toward Mars. ‘Mars is looking real,’ Elon Musk says.

The Starship SN5 test vehicle took to the skies for about 40 seconds this afternoon (Aug. 4) at SpaceX’s facilities near the South Texas village of Boca Chica, performing a small hop that could end up being a big step toward human exploration of the Red Planet. The stainless-steel SN5 rose into the air at 7:57 p.m. EDT (2357 GMT; 6:57 p.m. local Texas time). It travelled sideways a bit during the brief, uncrewed flight, which Musk had previously said would target a maximum altitude of about 500 feet (150 meters). The spacecraft deployed its landing legs as planned and stuck the landing. The SN5 is just the second Starship prototype to get off the ground, and the first to do so in nearly a year. A squat and stubby vehicle called Starhopper took a few brief flights in the summer of 2019, retiring after acing its own 500-foot-high hop that August.

Ending this flight lull fell to the SN5 after several of its predecessors were destroyed during pressurization or engine-firing tests. Starhopper and the SN5 both feature a single Raptor, SpaceX’s powerful next-generation engine. The final Starship vehicle will sport six Raptors, stand about 165 feet (50 m) tall and be capable of carrying up to 100 people, Musk has said. The operational Starship will launch from Earth atop a gigantic rocket called Super Heavy, which will have 31 Raptors of its own. Both vehicles will be fully and rapidly reusable, potentially slashing the cost of spaceflight enough to make crewed trips to and from the moon, Mars and other deep-space destinations economically feasible, Musk has said. Super Heavy will land back on Earth after each lift-off; Starship will be powerful enough on its own to get itself off Mars and the moon, both of which have much weaker gravitational pulls than our planet does.

Virgin Galactic delays SpaceShipTwo commercial flights to 2021

Virgin Galactic has pushed the beginning of commercial flights of its SpaceShipTwo suborbital vehicle to no earlier than the first quarter of 2021 while announcing plans to sell additional stock to raise money. The company, in its fiscal second quarter financial results released Aug. 3, said it expected to perform two more test flights of SpaceShipTwo from Spaceport America in New Mexico, both of which will be powered flights. The vehicle has made two glide flights since moving to the spaceport early this year.

The first of those powered flights, scheduled for the fall, will have two pilots on board. It will also carry payloads for NASA’s Flight Opportunities program that arranges flights of experiments on suborbital vehicles, said George Whitesides, chief space officer and former chief executive of Virgin Galactic, in a company earnings call. If that flight goes as expected, Virgin Galactic will then perform a second flight, this time with four mission specialists on board along with the two pilots. Those mission specialists “will evaluate the performance of our full customer cabin and associated hardware,” he said.

“Presuming things go as expected on this fully-crewed flight, we would then plan to fly Sir Richard Branson on the third powered flight from New Mexico,” he said. That flight would take place in the first quarter of 2021 and mark the beginning of commercial service, although Whitesides said it will also be a test flight of sorts. “Sir Richard is in a unique position to provide the ultimate cabin and spaceflight experience evaluation, as a visionary of the Virgin customer experience.”

Rocket Lab to resume Electron launches in August

Rocket Lab has received approval from the Federal Aviation Administration (FAA) to resume launches this month, after identifying an anomalous electrical connection as the cause of an in-flight failure on July 4, 2020. With corrective measures underway, the next Electron launch has been scheduled for August from Launch Complex 1. Over the past month, Rocket Lab has collaborated on an investigation with the support of the FAA, the primary federal licensing body for commercial space launch activity. Rocket Lab’s Accident Investigation Board (AIB) worked through an extensive fault tree analysis to examine all potential causes for the anomaly that took place late into Rocket Lab’s 13th launch.

On July 4, 2020, the Electron launch vehicle successfully lifted-off from Launch Complex 1 and proceeded through a nominal first stage engine burn, Stage 1-2 separation, Stage 2 ignition, and fairing jettison as planned. Several minutes into the second stage burn, the engine performed a safe shutdown resulting in a failure to reach orbit. Due to the controlled way the engine shut down, Rocket Lab continued to receive telemetry from the vehicle, providing engineers with extensive data to conduct a robust investigation into the issue.

Peter Beck, Rocket Lab’s founder and CEO stated that the Rocket Lab team is immensely grateful for the continued support of their customers and the FAA as the company worked meticulously through the flight investigation. “It’s a testament to Electron’s track record of reliability that the FAA has approved us for return to flight already. Electron was the 4th most frequently launched rocket in the world last year and prior to the anomaly we had deployed 53 customer payloads to orbit without fail. Returning to the pad with an even more reliable vehicle for our mission partners is our top priority.”

Rocket Lab is now set to return to the pad in August to launch a dedicated mission from Launch Complex 1 Pad A on New Zealand’s Māhia Peninsula. Specific details of the launch window will be provided. Read the full story for details of the investigation.

SpaceX Crew Dragon makes historic 1st splashdown to return NASA astronauts home

SpaceX’s first astronaut mission for NASA is in the books. A Crew Dragon capsule carrying NASA astronauts Bob Behnken and Doug Hurley splashed down off the coast of Pensacola, Florida, at 2:48 p.m. EDT (1848 GMT) August 2, bringing an end to SpaceX’s historic Demo-2 mission to the International Space Station. “Welcome back to planet Earth,” SpaceX’s mission control radioed the two astronauts aboard the capsule, which is named Endeavour. “Thanks for flying SpaceX.”

“It was truly our honor and privilege,” Hurley radioed back. Just hours earlier, while still in space, Hurley said the experience is one he won’t soon forget. “It’s hard to put into words just what it was like to be a part of this expedition — Expedition 63,” Hurley said during a farewell ceremony aboard the space station on Saturday (Aug. 1), the day Endeavour undocked and began its journey home. “It’ll be kind of a memory that will last a lifetime for me.”

The SpaceX recovery ship GO Navigator met Endeavour and hoisted the capsule aboard shortly after splashdown. After a series of checkouts, recovery teams opened Endeavour’s hatch at 3:59 p.m. EDT (1959 GMT) and extracted the two astronauts about 10 minutes later. Medical personnel can now begin assessing Behnken and Hurley, making sure the two spaceflyers are in good shape after their journey home from orbit. We haven’t seen such activity at sea for more than four decades. The most recent crewed ocean return occurred in July 1975, when NASA astronauts Tom Stafford, Vance Brand and Deke Slayton wrapped up the Apollo-Soyuz Test Project by splashing down in the middle of the Pacific.

The First UK Mission to the Moon

Learn about Spacebit Mission One: the United Kingdom’s first moon rover launch scheduled for 2021. The rover they are planning to send to the moon will be the world’s first walking rover. Asagumo rover is built on a single-unit CubeSat frame that is usually used for tiny satellites. Moon rover weighs just 1.3 kilogrammes, is solar-powered and instead of wheels or tracks, is equipped with four arachnid-like legs. The mission will be launched by the first ULA Vulcan mission in Q3 2021. The walking rover will be delivered to the Moon by Astrobotic’s Peregrine lunar lander spacecraft. During the first demo mission the walking rover will move 10 meters from the Peregrine lander and send Full HD video plus 3D LIDAR data from its onboard sensors. It will be a flight of firsts — the first mission for both Peregrine and its rocket, United Launch Alliance’s new Vulcan Centaur; the first trip to the moon’s surface by a UK-built craft; and the first time a legged robot has explored another world.

Working in partnership with Goonhilly Earth Station in Cornwall, Spacebit is also building a new ecosystem for ground based elements in space missions, including radio communications, ground networks and eventually components of mission control and they will be utilising Goonhilly’s existing network of over 60 dishes to run our pilot projects.

Thomas Pesquet named as the first ESA astronaut to ride a Dragon to space

ESA astronaut Thomas Pesquet has officially been assigned to the second operational flight of SpaceX’s Crew Dragon spacecraft, launching in spring 2021 from Cape Canaveral, USA, to the International Space Station. Thomas’ second mission to the International Space Station will be called Alpha. This is after Alpha Centauri, the closest stellar system to Earth, following the French tradition to name space missions after stars or constellations.

“I am thrilled to be the first European to fly on the new generation of US crewed spacecraft,” says Thomas. “It will be extra interesting for me to compare with my first flight as a Soyuz pilot, and to bring this experience to the team. The Dragon spacecraft is a modern machine with amazing new capabilities. On the other hand, the Soyuz has an unbelievable track record which enabled us to reach the International Space Station for many years. It is a privilege to fly on both.”
