SpaceX launches classified US spy satellite, sticks rocket landing to cap record year

Published

 on

CAPE CANAVERAL, Fla. — SpaceX launched a clandestine U.S. spy  satellite into space for the National Reconnaissance Office (NRO)  Saturday (Dec. 19) , marking its 26th rocket of the year.

The mysterious payload, called NROL-108, lifted off from Pad 39A here at NASA’s Kennedy Space Center at  9 a.m. (1400 GMT) , during a planned three hour launch window.

A used two-stage Falcon 9 rocket carried the spy satellite aloft, as part of a government mission called NROL-108, marking SpaceX’s 26th launch of 2020, a new record for the company. Approximately nine minutes after liftoff, the booster’s first stage produced some dramatic sonic booms as it made its way back to terra firma, touching down at SpaceX’s Landing Zone-1 (LZ-1) at the nearby Cape Canaveral Space Force Station.

Today’s flight was the fifth launch for this particular Falcon 9 first stage. The booster, designated B1059, previously lofted two commercial cargo missions to the International Space Station for NASA, delivered a batch of SpaceX Starlink satellites into orbit earlier this year, and most recently launched an Earth-observing satellite for Argentina.

Falcon 9 blasted off into a clear blue sky Saturday morning, a stark change from Thursday’s launch attempt. Thick clouds shrouded the rocket from view that day and ultimately an issue with the rocket’s second stage forced SpaceX to postpone the launch.

Several minutes after Falcon 9 leapt off the pad, the rocket’s first stage reappeared in the sky, with the iconic sonic booms you expect cracking overhead as the booster descended to the landing site.

B1059 is only the second booster to land on the ground at the Cape (as opposed to a drone ship at sea) this year. (A third landed on land at Vandenberg Air Force base in California following the launch of the Sentinel-6 Earth-observing satellite for NASA in November.) In fact, it’s now the third trip to LZ-1 for this booster, as the veteran Falcon 9 first stage also returned to land after delivering the CRS-20 mission into orbit earlier this year.

 A mystery payload

Today’s Falcon 9 launch carried a classified payload into orbit for the National Reconnaissance Office (NRO), the government agency that oversees the country’s fleet of spy satellites. Not much is known about the satellite except for the fact that the NRO secured the ride for the top secret cargo through non-traditional means.

Typically, the reconnaissance agency will secure its rides to space via the U.S. Space Force’s National Security Space Launch Program, but this time went about it on its own, according to a report from Spaceflight Now.

“In some cases, the NRO uses alternative methods to procure launch services after making a cumulative assessment of satellite risk tolerance, needed launch dates, available launch capabilities, and cost — all with a purpose of ensuring satellites are safely and securely delivered to orbit in a timely manner,” the spokesperson told Spaceflight Now.

Another interesting twist is that SpaceX did not conduct a static fire test of its rocket before flight. Typically, the company holds the rocket down on the pad and briefly fires its nine first-stage engines to make sure their systems are working as expected prior to liftoff. It’s rare that SpaceX skips this routine test but is not unheard of.

The mission marks the sixth launch of the year for the NRO, and will be the second overall to fly aboard a SpaceX Falcon 9. The first was the NROL-76 mission back in May 2017.

Falcon’s flight

The NROL-108 mission is SpaceX’s 50th reflight of a Falcon 9 since the company recovered its first booster in 2015. It also marks the 70th landing of a Falcon 9. To stick the landing, the booster separated from its upper stage and conducted a series of orbital ballet moves, reorienting itself for landing. Then it conducted a series of three engine burns to slow itself enough to gently touch down on its designated landing pad, marking the 21st successful land landing for SpaceX.

To facilitate reuse, the company normally relies on its two massive drone ships, named “Of Course I Still Love You” and “Just Read the Instructions,” the floating platforms are typically stationed out in the Atlantic Ocean and have enabled SpaceX to launch and subsequently land more rockets.

“Of Course I Still Love You” is sidelined for this mission, since the booster is returning to land, while “Just Read the Instructions” is currently bringing back a booster from the company’s most recent launch on Dce. 13. For that mission, a Falcon 9 rocket launched for the seventh time, carrying a massive satellite into space for SIrius XM. That booster is one of two that have flown that seven missions and should be sailing back into port around the same time as today’s launch.

Once they return to Florida’s Port Canaveral, the landed boosters are transported back to SpaceX facilities, where they’re carefully inspected and repurposed to fly again.

The current iteration of the Falcon 9 was finalized in 2018. Known as the Block 5, it features 1.7 million pounds of thrust as well as some other upgrades that make it capable of rapid reuse. SpaceX says that each of these boosters can fly as many as 10 times with minor refurbishments in between, and potentially as many as 100 times before retirement.

To date, SpaceX has launched and landed the same booster a maximum of seven times. According to company founder and CEO, Elon Musk, each Falcon 9 booster is capable of flying at least 10 times with minimal refurbishments in between flights. We have yet to see one fly that many times, but could see it next year.

Rocket fairing recovery

Ahead of today’s launch, SpaceX deployed one of its twin fairing catchers, GO Ms. Tree, to fetch the fairing pieces after today’s launch. GO Miss Chief, the company’s other fairing recovery vessel, stayed in port for the second mission in a row. These two boats act as giant, mobile catcher’s mitts, snagging payload fairings — the protective nose cones that surrounds satellites during launch — in their attached nets as they fall back down to Earth.

To that end, SpaceX has installed parachutes and special software in its payload fairings, which consist of two joined pieces. The fairings are designed to guide themselves to the recovery zone where Ms. Tree and Ms. Chief can wait to snag them as they fall back to Earth. If the boats miss or the weather is too poor to attempt a catch, the duo has on board equipment to scoop the fairing pieces up out of the water and carry them back to port for refurbishment.

The company has been successfully reusing the payload fairings, and the last mission — which launched the Sirius XM-7 satellite — was the first flight to feature a refurbished fairing on a non-SpaceX payload. Typically the company has been reusing fairings on its own Starlink missions. One of the fairing pieces that shrouded the Sirius XM-7 payload as it traveled through the atmosphere previously flew on the Anasis-II mission earlier this summer, which launched a communications satellite for South Korea’s military.

Today’s mission will mark the end of a busy launch year for the Cape. In total 31 missions have launched from the area this year, and 26 of those have been on SpaceX rockets. Next year, SpaceX is expected to continue to fill in its fleet of Starlink satellites, launch two more astronaut missions, and one of its heavy-lifters, the Falcon Heavy.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.

Asteroid Apophis will visit Earth in 2029, and this European satellite will be along for the ride

Published

 on

The European Space Agency is fast-tracking a new mission called Ramses, which will fly to near-Earth asteroid 99942 Apophis and join the space rock in 2029 when it comes very close to our planet — closer even than the region where geosynchronous satellites sit.

Ramses is short for Rapid Apophis Mission for Space Safety and, as its name suggests, is the next phase in humanity’s efforts to learn more about near-Earth asteroids (NEOs) and how we might deflect them should one ever be discovered on a collision course with planet Earth.

In order to launch in time to rendezvous with Apophis in February 2029, scientists at the European Space Agency have been given permission to start planning Ramses even before the multinational space agency officially adopts the mission. The sanctioning and appropriation of funding for the Ramses mission will hopefully take place at ESA’s Ministerial Council meeting (involving representatives from each of ESA’s member states) in November of 2025. To arrive at Apophis in February 2029, launch would have to take place in April 2028, the agency says.

This is a big deal because large asteroids don’t come this close to Earth very often. It is thus scientifically precious that, on April 13, 2029, Apophis will pass within 19,794 miles (31,860 kilometers) of Earth. For comparison, geosynchronous orbit is 22,236 miles (35,786 km) above Earth’s surface. Such close fly-bys by asteroids hundreds of meters across (Apophis is about 1,230 feet, or 375 meters, across) only occur on average once every 5,000 to 10,000 years. Miss this one, and we’ve got a long time to wait for the next.

When Apophis was discovered in 2004, it was for a short time the most dangerous asteroid known, being classified as having the potential to impact with Earth possibly in 2029, 2036, or 2068. Should an asteroid of its size strike Earth, it could gouge out a crater several kilometers across and devastate a country with shock waves, flash heating and earth tremors. If it crashed down in the ocean, it could send a towering tsunami to devastate coastlines in multiple countries.

Over time, as our knowledge of Apophis’ orbit became more refined, however, the risk of impact  greatly went down. Radar observations of the asteroid in March of 2021 reduced the uncertainty in Apophis’ orbit from hundreds of kilometers to just a few kilometers, finally removing any lingering worries about an impact — at least for the next 100 years. (Beyond 100 years, asteroid orbits can become too unpredictable to plot with any accuracy, but there’s currently no suggestion that an impact will occur after 100 years.) So, Earth is expected to be perfectly safe in 2029 when Apophis comes through. Still, scientists want to see how Apophis responds by coming so close to Earth and entering our planet’s gravitational field.

“There is still so much we have yet to learn about asteroids but, until now, we have had to travel deep into the solar system to study them and perform experiments ourselves to interact with their surface,” said Patrick Michel, who is the Director of Research at CNRS at Observatoire de la Côte d’Azur in Nice, France, in a statement. “Nature is bringing one to us and conducting the experiment itself. All we need to do is watch as Apophis is stretched and squeezed by strong tidal forces that may trigger landslides and other disturbances and reveal new material from beneath the surface.”

By arriving at Apophis before the asteroid’s close encounter with Earth, and sticking with it throughout the flyby and beyond, Ramses will be in prime position to conduct before-and-after surveys to see how Apophis reacts to Earth. By looking for disturbances Earth’s gravitational tidal forces trigger on the asteroid’s surface, Ramses will be able to learn about Apophis’ internal structure, density, porosity and composition, all of which are characteristics that we would need to first understand before considering how best to deflect a similar asteroid were one ever found to be on a collision course with our world.

Besides assisting in protecting Earth, learning about Apophis will give scientists further insights into how similar asteroids formed in the early solar system, and, in the process, how  planets (including Earth) formed out of the same material.

One way we already know Earth will affect Apophis is by changing its orbit. Currently, Apophis is categorized as an Aten-type asteroid, which is what we call the class of near-Earth objects that have a shorter orbit around the sun than Earth does. Apophis currently gets as far as 0.92 astronomical units (137.6 million km, or 85.5 million miles) from the sun. However, our planet will give Apophis a gravitational nudge that will enlarge its orbit to 1.1 astronomical units (164.6 million km, or 102 million miles), such that its orbital period becomes longer than Earth’s.

It will then be classed as an Apollo-type asteroid.

Ramses won’t be alone in tracking Apophis. NASA has repurposed their OSIRIS-REx mission, which returned a sample from another near-Earth asteroid, 101955 Bennu, in 2023. However, the spacecraft, renamed OSIRIS-APEX (Apophis Explorer), won’t arrive at the asteroid until April 23, 2029, ten days after the close encounter with Earth. OSIRIS-APEX will initially perform a flyby of Apophis at a distance of about 2,500 miles (4,000 km) from the object, then return in June that year to settle into orbit around Apophis for an 18-month mission.

Furthermore, the European Space Agency still plans on launching its Hera spacecraft in October 2024 to follow-up on the DART mission to the double asteroid Didymos and Dimorphos. DART impacted the latter in a test of kinetic impactor capabilities for potentially changing a hazardous asteroid’s orbit around our planet. Hera will survey the binary asteroid system and observe the crater made by DART’s sacrifice to gain a better understanding of Dimorphos’ structure and composition post-impact, so that we can place the results in context.

The more near-Earth asteroids like Dimorphos and Apophis that we study, the greater that context becomes. Perhaps, one day, the understanding that we have gained from these missions will indeed save our planet.
