The aerospace manufacturing company, SpaceX, successfully launched the second classified US spy satellite on April 17. The satellite was sent off in a SpaceX Falcon 9 Rocket. The launch happened from the Vandenberg Air Force Base in California. Read on to know more about the journey into orbit.
The launch happened on a Sunday afternoon at the Air Force base in California. This satellite was sequestered in the Falcon 9 Rocket. The rocket was launched by the National Reconnaissance Office (NRO) and it’s their second launch this year. This launch was initially delayed twice due to some issues and finally took place on April 17. The launch happened at 20:27 GMT. The NRLO-85 was the name of the satellite sent to space. According to this NRO, the NROL-85 satellite was a critical national security payload. It was also stated that the satellite was vital in assisting in securing vital intelligence data. After the launch, the booster successfully separated from the payload. It returned and landed autonomously upright.
National Reconnaissance Office
The NRO is a government agency in the US that is responsible for everything from building to operating US spy satellites. These satellites have been responsible for providing data to the Defence Department and 18 US intelligence community agencies. Over the last two years, the NRO has launched over 16 different satellites. This is NRO’s second launch this year, the first was the launch of NROL-87.
The Falcon 9
Falcon 9 is a rocket designed and owned by SpaceX and has seen massive successes in its previous missions. The latest launch marked the rocket’s 14th mission this year, and its 148th mission overall, which is no small feat. Even though SpaceX has regular contact with the NRO, this is also the first time that the office has reused a Falcon 9 booster. SpaceX has been assisting the US government with private launches since 2014.
A Strange Underground Fish Was Recently Discovered in India
A team of researchers has made a stunning discovery in underground waters in southern India. They found living members of a family of eel-like fish, which is named dragon snakeheads. These primitive fish are considered a “living fossil” because they are believed to have diverged from their relatives some hundred million years ago.
The Dragon Snakehead Joins a New Family of Fish
In taxonomy, the family is the category placed above genus and species, and discovering a new one is not very common. Usually, taxonomic families are large and diverse, but the new fish family includes only two species. The first one is named the Gollum snakehead, after the famous Lord of the Rings character, and the dragon snakehead is now the second member of this family.
The study leader Ralf Britz shared that he believes this might be the most exciting discovery in the fish world for the last decade. These long-bodied fish usually dwell in aquifers of porous rock, which explains why they are rarely seen. They would only come to the surface after heavy-rain floods.
The fish live in the Western Ghats of southern India, which is known as a biodiversity hot spot. In the aquifers there, scientists have discovered ten new species of subterranean fish. However, the water there is used for around six million wells, and this lowers the water table, putting some of the obscure species that call it home in peril.
Enigmatic Fish Species
Back in 2018, researcher and study co-author Rajeev Raghavan saw a photo of an odd fish that was retrieved from a backyard well. He and Britz had no idea what the species, genus, and family of the fish were and described it as a new species and genus – Aenigmachanna Gollum or the Gollum snakehead. During a similar and more recent discovery, Britz and his colleagues thought they found the same fish in another well. After performing further research on their genetics and anatomy, they found they belong in a whole new family.
The new dragon snakeheads exhibit a series of primitive characteristics, and these unique traits include fewer vertebrae with ribs, a shortened swim bladder, and a lack of a suprabranchial organ. These features show that the dragon snakeheads are not as specialized as regular snakeheads and can really be called “living fossils.” Genetic analysis showed that dragon snakeheads diverged from their nearest relatives over 120 million years ago when Africa and India were still the same landmass.
