CAPE CANAVERAL, Fla. — SpaceX successfully launched an advanced GPS satellite for the U.S. Space Force on Thursday (Nov. 5), marking the first launch in nearly two weeks here on the Space Coast.
One of the company’s two-stage Falcon 9 rockets blasted off from Space Launch Complex 40 at Cape Canaveral Air Force Station here at 6:24 p.m. EST (2324 GMT), carrying the GPS III-SV04 satellite to orbit. Nine minutes later, the rocket’s first stage touched down on the deck of “Of Course I Still Love You,” one of SpaceX’s two drone ships.
The GPS III-SV04 mission had been set to follow on the heels of a United Launch Alliance (ULA) Atlas V rocket, which was scheduled to loft a U.S. spy satellite from Cape Canaveral on Tuesday (Nov. 3). However, the Atlas V launch was delayed twice due to issues with ground systems equipment. ULA is now targeting Friday (Nov. 6) for that liftoff.
It was a crystal clear night here on the Space Coast, and onlookers were able to follow the rocket through the different phases of launch. A nebula-like cloud, typically visible on clear nights, formed around the rocket as the first and second stages separated. The booster’s reentry burn was also visible from a press viewing area.
Tonight’s GPS mission had been waiting to get off the ground since SpaceX was forced to call an abort on Oct. 2. In the final seconds of the countdown that day, the Falcon 9’s computer detected an engine anomaly, and the rocket’s onboard flight termination system shut the engines down. Crews were able to safe the vehicle and, after a thorough investigation, pinpoint the issue.
SpaceX determined that residue from a “masking lacquer,” which is designed to protect sensitive engine parts during anti-corrosion anodizing treatment, was left behind post-treatment. The lacquer ended up blocking 0.06-inch-wide (1.6 millimeters) vent holes for valves in two of the nine Merlin engines on the Falcon 9’s first stage, SpaceX representatives said in a news briefing on Oct. 28.
The same traces of lacquer were detected in engines on two other Falcon 9 first stages — one on the rocket that will launch the Sentinel-6 Earth-observation satellite and one on the booster that will launch Crew-1, SpaceX’s next astronaut mission. SpaceX has swapped out the affected engines. The Crew-1 launch date, scheduled for Nov. 14, was not affected by this swap. However, SpaceX and NASA are postponing the Sentinel-6 mission until after Crew-1, setting a new target date of Nov. 21.
Today’s flight marks the third GPS delivery for SpaceX. Two previous advanced GPS III missions also launched on Falcon 9 rockets, including one this past June. Another of the satellites launched on the final flight of ULA’s Delta IV Medium in August 2019.
The U.S. military plans to launch a total of 10 upgraded GPS satellites, which will replace aging members of its current constellation. SpaceX has secured additional contracts to launch the next two GPS III missions, which are expected to lift off sometime next year.
Built by Lockheed Martin in Colorado, the GPS III-SV04 satellite launched today is the fourth member of an upgraded generation of GPS navigation spacecraft that beam down higher-power signals that are more resilient to jamming and boast additional broadcast frequencies to make the GPS network more compatible with other similar constellations, Lockheed representatives have said.
The 227-foot-tall (70 meters) Falcon 9 is SpaceX’s workhorse, and the rocket boasts more than 1.5 million pounds of thrust at liftoff. Today’s mission featured a fresh-off-the-factory-floor Falcon, its exterior stark white for its first trip to space.
SpaceX has been relying heavily on its fleet of veteran rockets, with many Falcon 9 first stages having racked up five or more flights each. The booster that launched today, known by the SpaceX designation B1062, could be the last brand-new one we see launch a GPS satellite, as the U.S. government has given SpaceX the green light to launch future military missions on flight-proven boosters.
That decision followed on the heels of another recent announcement to allow SpaceX to recover the rocket’s first stage during national security missions — something that was previously not allowed. The next two GPS missions, which are already scheduled to fly on SpaceX rockets sometime next year, will now launch atop refurbished rockets.
That announcement is a first for national-security payloads and could result in savings of nearly $53 million for American taxpayers across the two flights, Space Force officials said.
What’s in a name?
The military has given nicknames to each of the upgraded GPS satellites, naming them after famous explorers. The satellite that launched tonight was given the moniker “Sacagawea” after the Shoshone guide who helped Lewis and Clark on their expedition through the American West in the early 1800s.
Previous satellites have been named “Vespucci” and “Magellan” in honor of explorers Amerigo Vespucci and Ferdinand Magellan. The satellite that launched in June was originally dubbed Columbus, but it recently received a new nickname: “Henson,” in honor of black explorer Matthew Henson, who was part of the first expedition to the North Pole more than a century ago.
All of the monikers are unofficial nicknames given to the satellites prior to launch as a way of honoring explorers of the past and continuing a spaceflight tradition of naming spacecraft.
The next few missions already have names selected for the respective satellites. The fifth satellite, GPS III-SV05, will be called Neil Armstrong. Space Force officials say other satellites to come will be named after Amelia Earhart, Sally Ride and Katherine Johnson.
Today’s mission marks the 97th Falcon 9 rocket to fly and the 20th mission of 2020 for SpaceX. It also marks the 64th successful booster recovery. SpaceX’s drone ship, “Of Course I Still Love You,” was positioned out in the Atlantic Ocean, awaiting its recovery attempt.
The company’s other drone ship, “Just Read the Instructions,” is hanging out in Port Canaveral for now, awaiting its next mission. The massive ship, which now has 11 rocket catches under its belt, transferred to the East Coast earlier this year, after receiving some sweet upgrades.
Today’s launch also was the first since August to feature a brand new SpaceX booster. The engine issue temporarily grounded SpaceX’s new boosters, allowing the company to focus on veteran rockets and its own Starlink internet constellation. In the month of October, SpaceX launched a record 180 Starlink satellites, bringing the total number launched to nearly 900.
B1062 was the star of the show today, and it will also likely be the first Falcon 9 booster to carry two different GPS satellites to orbit; it’s scheduled to launch the next one, sometime next year. This will mark the first time that a previously flown Falcon 9 will hoist one of these advanced global positioning satellites.
With the last Starlink mission, which launched on Oct. 24, SpaceX hit a major milestone: 100 successful Falcon launches. This total encompasses the entire Falcon family, including the pioneering (and long discontinued) Falcon 1 and the currently operational Falcon Heavy. SpaceX tweeted out a video recently to commemorate the milestone.
One of SpaceX’s two fairing catchers, GO Ms. Chief, is waiting in the recovery zone this evening. The two boats are outfitted with massive nets to catch the falling pieces of the rocket’s payload fairing, or nose cone, after they are deployed during flight. (SpaceX fairings come back to Earth in two halves.)
GO Ms. Chief departed Port Canaveral on Wednesday (Nov. 4) ahead of today’s launch. The vessel traveled solo this time as its counterpart, GO Ms. Tree, remained in Port in Florida. (The boat was damaged on a previous mission and could presumably still be undergoing repairs.)
During a prelaunch broadcast, SpaceX engineer Jessica Anderson announced that the company would not be attempting a catch, but instead would scoop up the fairing pieces after they land in the ocean. The boats have the capability of catching falling fairings in their nets, or scooping them out of the water after they splash down. Those efforts should occur approximately 45 minutes after liftoff.
With the help of Ms. Tree and Ms. Chief, SpaceX has been successful in its attempts to reuse more of the rocket, even reusing several fairings on multiple missions.
Up next for SpaceX is Crew-1, its first contracted crewed mission to the International Space Station for NASA. A different Falcon 9 rocket will ferry four astronauts to the station for a six-month stay. That flight is set to blast off from Pad 39A at NASA’s Kennedy Space Center in Florida on Nov. 14 at 7:29 p.m. EST (0029 GMT on Nov. 15).

NOAA scientists discover new species of gelatinous animal near Puerto Rico – CTV News
Scientists have discovered a new species of ctenophore, or comb jelly, near Puerto Rico.
The newly named Duobrachium sparksae was discovered two and a half miles below sea level by the National Oceanic and Atmospheric Administration Fisheries research team. It was found during an underwater expedition using a remotely operated vehicle in 2015 and filmed by a high-definition camera.
NOAA Fisheries scientists Mike Ford and Allen Collins spotted the ctenophore and recognized it as a new species. This is the first time NOAA scientists have identified a new species using only high-definition video, according to NOAA.
“The cameras on the Deep Discoverer robot are able to get high-resolution images and measure structures less than a millimeter. We don’t have the same microscopes as we would in a lab, but the video can give us enough information to understand the morphology in detail, such as the location of their reproductive parts and other aspects,” Collins said.
The scientists also said there was another unique quality to the discovery. During the expedition, they were not able to gather any samples, so the video evidence is all they have.
“Naming of organisms is guided by international code, but some changes have allowed descriptions of new species based on video — certainly when species are rare and when collection is impossible,” Ford said. “When we made these observations, we were 4,000 metres down, using a remote vehicle, and we did not have the capabilities to take a sample.”
There are between 100 and 150 species of comb jellies, and despite their name, they are not related to jellyfish at all, according to the NOAA. The species is carnivorous, and many are highly efficient predators that eat small arthropods and many kinds of larvae.
The researchers said that there did not initially get a long look at the animal, so there is still a lot about this new species that they do not know yet. Their findings were recently published in the journal Plankton and Benthos Research.
“We’re not sure of their role in the ecosystem yet,” Ford said.
“We can consider that it serves similar roles to other ctenophores near the ocean floor and it also has some similarities to other ctenophores in open ocean areas,” he said.
The videos are now part of the Smithsonian National Museum of Natural History Collection and publicly accessible.
You might want to stay up late: lunar eclipse to coincide with November’s Beaver full moon early Monday morning – Toronto Star
A special celestial event is set to grace Toronto skies early Monday morning.
The November full moon, which is traditionally called the Beaver moon, will coincide with a penumbral lunar eclipse.
This kind of eclipse event happens when the moon crosses Earth’s outer shadow, or penumbra, giving it a reddish brown hue.
Those in Toronto will be able to observe the phenomenon starting 2:29 a.m. ET. The eclipse will be at its peak at 4:42 a.m. ET.
Environment Canada predicts partly cloudy skies at that time, but stargazing enthusiasts may be able to get a glimpse of the moon.
Although the Canadian Space Agency notes lunar eclipses are usually among the most observable because you can see them — quite safely — with the naked eye, with the more subtle penumbral eclipse they recommend using binoculars or a small telescope for the best viewing experience.
Fourth and last lunar eclipse of 2020 to occur on Monday – Geo News
The fourth and last lunar eclipse of 2020, a penumbral eclipse, will occur on November 30 (Monday).
According to Prof Dr Javed Iqbal, of the Institute of Space and Planetary Astrophysics (ISPA), University of Karachi, the eclipse will take place at 12:32pm according to Pakistan Standard Time.
The lunar eclipse will be seen in South and North America, Australia and Asian countries and will not be seen anywhere in Pakistan.
It will reach its peak at 2:42pm, Dr Iqbal said, adding that the shadow of the eclipse will be removed from the moon at 4:53pm.
The total duration of the eclipse will last 4 hours and 21 minutes, Dr Iqbal said.
The last three lunar eclipses occurred on January 10, June 5, and July 4.
A penumbral eclipse occurs when the Earth blocks some of the sun’s light from directly reaching the moon’s surface. All or part of the moon is covered with the outer part of its shadow, also known as the penumbra.
