SpaceX launches Turksat 5A communications satellite for Turkey, lands rocket – Space.com

Published

CAPE CANAVERAL, Fla. — SpaceX kicked off what is expected to be another launch-packed year by delivering a Turkish communications satellite to orbit tonight (Jan. 7). 

A 230-ft-tall (70 m) Falcon 9 rocket blasted off from Space Launch Complex 40 here at Cape Canaveral Space Force Station at 9:15 p.m. EST (0215 GMT on Jan. 8), about 45 minutes into a planned four-hour window, carrying the Turksat 5A satellite into space. The brief delay was due to a downrange tracking issue, SpaceX said during its live launch broadcast. 

Going into the launch tonight, forecasters at the U.S. Space Force’s 45th Space Wing predicted a 70% chance of favorable conditions for launch, with the main concerns being cumulus and thick clouds, along with upper-level wind shear. These conditions aren’t always ideal for onlookers but can allow interesting acoustics as the roar of the Falcon sounds extra loud.

Falcon’s flight

The two-stage Falcon 9 lit up the night sky as it leapt off the launch pad tonight. The glow of the rocket’s nine first-stage engines turned night into day as the rocket climbed into the clouds hanging over the Space Coast. The rumble of the engines could be heard long after the rocket disappeared from sight.

Tonight’s mission marked the first launch of the year here at the Cape, and 8.5 minutes after liftoff, the rocket’s first stage landed on one of SpaceX’s two massive drone ships, “Just Read the Instructions,” which was stationed out in the Atlantic Ocean. 

Today’s flight was the fourth launch for this particular Falcon 9 first stage. The booster, designated B1060, previously lofted an upgraded GPS III satellite for the U.S. Space Force in June 2020, followed by launches of SpaceX’s Starlink internet satellites in September and October.

The Falcon 9 went vertical on the pad this morning. SpaceX did not conduct a static fire test of this particular 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 it’s not unheard of. In fact, SpaceX skipped the static fire test on its previous mission as well, which launched a spy satellite for the U.S. National Reconnaissance Office in December. 

Powered by more than 1.7 million pounds of thrust from its nine first-stage Merlin 1D engines, the Falcon 9 deposited the 7,700-lb. (3,500 kilograms) Turksat 5A satellite into orbit about 33 minutes after liftoff. The spacecraft is designed to operate for approximately 15 years, providing broadband coverage to Turkey, the Middle East, Europe and portions of Africa. 

SpaceX will also launch the spacecraft’s counterpart, Turksat 5B, later this year. The Turksats are part of an effort to expand Turkey’s presence in space, which hasn’t been without controversy. In October, activists began pressuring SpaceX to stop the Turksat 5A launch. They protested outside SpaceX’s headquarters in Hawthorne, California, citing Turkey’s role in a conflict between Armenia and Azerbaijan as the reason the mission shouldn’t fly. Their attempt was unsuccessful. 

About 8.5 minutes after Falcon 9 leapt off the pad, the rocket’s first stage landed on the drone ship, marking the third successful launch and landing for this particular booster. The landing also marked the 71st successful touchdown for a returning SpaceX booster overall and the 21st in a row. (In 2019, SpaceX lost two first-stage boosters in back-to-back missions as the vehicles failed to hit their mark.)

Expanding Turkey’s space presence

Built by Airbus, the Turksat 5A spacecraft separated from the Falcon’s upper stage approximately 30 minutes after liftoff. From its orbital perch, more than 22,000 miles (36,00 kilometers) above Earth, the satellite will beam down broadband coverage, thanks to its 42 Ku-band transponders. 

It will take the satellite nearly four months to reach its final altitude. Turksat 5A will make the trek using its onboard plasma thrusters, which rely on electrical energy from the spacecraft’s solar panels rather than traditional fuel. These thrusters are more energy efficient but produce less thrust, so it takes a bit longer to reach its orbital parking spot.

“We are very pleased to welcome Turksat as a new Eurostar customer for the most powerful satellites of their fleet. We were the first to demonstrate full electric propulsion technology for satellites of this size and capacity, and this will enable the Turksat spacecraft to be launched in the most cost-efficient manner,” Nicolas Chamussy, head of space systems at Airbus, said in a company statement.

Turksat 5B, which is slated to launch later this year, is a bit heavier than its predecessor. Weighing in at more than 9,000 lbs. (4,500 kg), the satellite will operate in both the Ku and Ka bands, providing more than 50 gigabits per second of capacity, according to Airbus. That satellite is expected to enter service later this year, if all goes as planned.

Stick it to the drone ship

The Turksat 5A mission is SpaceX’s 50th reflight of a Falcon 9 since the company recovered a booster for the first time in 2015.

To stick the landing, the booster separated from its upper stage and conducted a series of orbital ballet moves, to reorient itself for landing. Then it performed a series of three engine burns to slow itself enough to gently touch down on its designated landing spot, the deck of “Just Read the Instructions.”

To facilitate reuse, SpaceX employs two massive drone ships, the second of which is named “Of Course I Still Love You.” The floating platforms are stationed in the Atlantic prior to launches from the Space Coast and return to Port Canaveral with the booster in tow following a successful catch. These two vessels have enabled SpaceX to launch and subsequently land more rockets. 

“Of Course I Still Love You” is now receiving some TLC after a busy year last year. In total OCISLY has caught 40 returning boosters, 13 of which landed in 2020. The ship will soon return to service, ready to catch many more boosters with SpaceX’s busy schedule for this year. 

“Just Read the Instructions” received its own upgrades and renovations at the beginning of 2020. 

Reusability efforts 

The current iteration of the Falcon 9 debuted in 2018. Known as the Block 5, it features 1.7 million pounds of first-stage thrust as well as some other upgrades that make it capable of rapid reuse. According to SpaceX, each of these first-stage 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. So far we have yet to see one fly 10 times, but that could happen this year. 

Company founder and CEO Elon Musk has said that he wants his rockets to help facilitate access to space, and the Block 5 Falcon 9 was created to do that. Thanks to the launcher’s capabilities, it has enabled smaller countries and organizations to reach space through dedicated missions and “rideshares.” 

With this flight, Turkey has become the latest country to take advantage of that opportunity. A little over two years ago, Bangladesh sent its first-ever communications satellite into space atop a SpaceX rocket; last July, South Korea launched its first dedicated military satellite from Florida’s Space Coast; and in 2018, Israel launched a spacecraft to the moon as part of a rideshare mission. These are just a few examples of the growing number of countries and entities that are reaching for the stars thanks to reduced launch costs.

Fairing recovery

Ahead of today’s launch, SpaceX deployed its dynamic duo — GO Ms. Tree and GO Ms. Chief — in an effort to fetch the two falling pieces of the Falcon 9’s payload fairing, or nose cone. 

Ms. Tree had been working solo for the final few missions of 2020, getting an assist from a boat named GO Navigator. 

Ms. Tree and Ms. Chief serve as giant, mobile catcher’s mitts, snagging payload fairings in their attached nets as they fall back down to Earth. (The boats are also capable of retrieving fairing halves rom the water after they splash down.)

Each fairing piece is equipped with parachutes and special software to guide itself to a predetermined recovery zone where the boats are waiting with their outstretched nets. 

Once returned to port, the fairings are refurbished and used again. Typically, SpaceX flies used fairing pieces on its own Starlink missions, but the company has been branching out and using more reused hardware on all its missions. In December, the company flew a veteran fairing on its Sirius XM-7 mission, the first external mission to feature a refurbished shroud. 

Today’s mission marks the beginning of a busy launch year for the Cape. More than 40 missions are on the schedule, with SpaceX hoping to launch 40 rockets this year between its California and Florida launch sites. 

Those launches include two astronaut missions to the International Space Station, more Starlink flights, and one liftoff of SpaceX’s powerful Falcon Heavy

Up next for SpaceX is the Transporter-1 mission, which is slated to transport 72 small satellites along with four additional payloads into space as part of SpaceX’s latest rideshare endeavor. Transporter-1’s liftoff is scheduled for no earlier than Jan. 14.

SpaceX sent up the 30th launch from the Space Coast for the year on the evening of April 23, a mission that also featured the company’s 300th successful booster recovery.

A Falcon 9 rocket carrying 23 of SpaceX’s Starlink internet satellites blasted off at 6:17 p.m. Eastern time from Cape Canaveral Space Force Station’s Space Launch Complex 40.

The first-stage booster set a milestone of the 300th time a Falcon 9 or Falcon Heavy booster made a successful recovery landing, and the 270th time SpaceX has reflown a booster.

This particular booster made its ninth trip to space, a resume that includes one human spaceflight, Crew-6. It made its latest recovery landing downrange on the droneship Just Read the Instructions in the Atlantic Ocean.

The company’s first successful booster recovery came in December 2015, and it has not had a failed booster landing since February 2021.

The current record holder for flights flew 11 days ago making its 20th trip off the .

SpaceX has been responsible for all but two of the launches this year from either Kennedy Space Center or Cape Canaveral with United Launch Alliance having launched the other two.

SpaceX could knock out more launches before the end of the month, putting the Space Coast on pace to hit more than 90 by the end of the year, but the rate of launches by SpaceX is also set to pick up for the remainder of the year with some turnaround times at the Cape’s SLC-40 coming in less than three days.

That could amp up frequency so the Space Coast could surpass 100 launches before the end of the year, with the majority coming from SpaceX. It hosted 72 launches in 2023.

More launches from ULA are on tap as well, though, including the May 6 launch atop an Atlas V rocket of the Boeing CST-100 Starliner with a pair of NASA astronauts to the International Space Station.

ULA is also preparing for the second launch ever of its new Vulcan Centaur rocket, which recently received its second Blue Origin BE-4 engine and is just waiting on the payload, Sierra Space’s Dream Chaser spacecraft, to make its way to the Space Coast.

Blue Origin has its own it wants to launch this year as well, with New Glenn making its debut as early as September, according to SLD 45’s range manifest.

Wildlife Wednesday: loons are suffering as water clarity diminishes – Canadian Geographic

Published

 on


The common loon, that icon of northern wilderness, is under threat from climate change due to declining water clarity. Published earlier this month in the journal Ecology, a study conducted by biologists from Chapman University and Rensselaer Polytechnic Institute in the U.S. has demonstrated the first clear evidence of an effect of climate change on this species whose distinct call is so tied to the soundscape of Canada’s lakes and wetlands.

Through the course of their research, the scientists found that July rainfall results in reduced July water clarify in loon territories in Northern Wisconsin. In turn, this makes it difficult for adult loons to find and capture their prey — mainly small fish — underwater, meaning they are unable to meet their chicks’ metabolic needs. Undernourished, the chicks face higher mortality rates. The consistent foraging techniques used by loons across their range means this impact is likely echoed wherever they are found — from Alaska to Canada to Iceland.

The researchers used Landsat imagery to find that there has been a 25-year consistent decline in water clarity, and during this period, body weights of adult loon and chicks alike have also declined. With July being the month of most rapid growth in young loons, the study also pinpointed water clarity in July as being the greatest predictor of loon body weight.

One explanation for why heavier rainfall leads to reduced water clarity is the rain might carry dissolved organic matter into lakes from adjacent streams and shoreline areas. Lawn fertilizers, pet waste and septic system leaks may also be to blame.

The researchers, led by Chapman University professor Walter Piper, hope to use these insights to further conservation efforts for this bird Piper describes as both “so beloved and so poorly understood.”

Giant prehistoric salmon had tusk-like teeth for defence, building nests

Published

 on

The artwork and publicity materials showcasing a giant salmon that lived five million years ago were ready to go to promote a new exhibit, when the discovery of two fossilized skulls immediately changed what researchers knew about the fish.

Initial fossil discoveries of the 2.7-metre-long salmon in Oregon in the 1970s were incomplete and had led researchers to mistakenly suggest the fish had fang-like teeth.

It was dubbed the “sabre-toothed salmon” and became a kind of mascot for the Museum of Natural and Cultural History at the University of Oregon, says researcher Edward Davis.

But then came discovery of two skulls in 2014.

300x250x1

Davis, a member of the team that found the skulls, says it wasn’t until they got back to the lab that he realized the significance of the discovery that has led to the renaming of the fish in a new, peer-reviewed study.

“There were these two skulls staring at me with sideways teeth,” says Davis, an associate professor in the department of earth sciences at the university.

In that position, the tusk-like teeth could not have been used for biting, he says.

“That was definitely a surprising moment,” says Davis, who serves as director of the Condon Fossil Collection at the university’s Museum of Natural and Cultural History.

“I realized that all of the artwork and all of the publicity materials and bumper stickers and buttons and T-shirts we had just made two months prior, for the new exhibit, were all out of date,” he says with a laugh.

Davis is co-author of the new study in the journal PLOS One, which renames the giant fish the “spike-toothed salmon.”

It says the salmon used the tusk-like spikes for building nests to spawn, and as defence mechanisms against predators and other salmon.

The salmon lived about five million years ago at a time when Earth was transitioning from warmer to relatively cooler conditions, Davis says.

It’s hard to know exactly why the relatives of today’s sockeye went extinct, but Davis says the cooler conditions would have affected the productivity of the Pacific Ocean and the amount of rain feeding rivers that served as their spawning areas.

Another co-author, Brian Sidlauskas, says a fish the size of the spike-toothed salmon must have been targeted by predators such as killer whales or sharks.

“I like to think … it’s almost like a sledgehammer, these salmon swinging their head back and forth in order to fend off things that might want to feast on them,” he says.

Sidlauskas says analysis by the lead author of the paper, Kerin Claeson, found both male and female salmon had the “multi-functional” spike-tooth feature.

“That’s part of our reason for hypothesizing that this tooth is multi-functional … It could easily be for digging out nests,” he says.

“Think about how big the (nest) would have to be for an animal of this size, and then carving it out in what’s probably pretty shallow water; and so having an extra digging tool attached to your head could be really useful.”

Sidlauskas says the giant salmon help researchers understand the boundaries of what’s possible with the evolution of salmon, but they also capture the human imagination and a sense of wonder about what’s possible on Earth.

“I think it helps us value a little more what we do still have, or I hope that it does. That animal is no longer with us, but it is a product of the same biosphere that sustains us.”
