The Department of the U.S. Air Force awarded SpaceX a National Security Space Launch Phase 2 Launch Service contract valued at $316 million. The military launches will be conducted by SpaceX’s Falcon 9 and Falcon Heavy rockets, between 2022 and 2027. One of the requirements for the Phase 2 contract is that SpaceX must have the capability to do a vertical payload integration at their launch site. SpaceX President, Gwynne Shotwell, told reporters–

“The only modifications we need are an extended fairing on the Falcon Heavy, and we are going to have to build a vertical integration capability. But we are basically flying the rockets that they need.”

Tesla still dominates electric car sales in China, over 11,000 deliveries in July

Posted by in category: biotech/medical

Tesla’s Model 3 leads the EV sales in China with 11,014 vehicles sold in July. That’s more than the next 3 best-selling EVs combined!


In China this morning, the China Association of Automobile Manufacturers (CAAM) held a press conference in Beijing to update the public on the status of the automotive industry’s recovery.

Overall, it is good news for the market, which managed to recover from the global pandemic much quicker than the rest of the world.

China to step up testing on fastest-ever maglev train

Posted by in category: transportation

Besides China, Germany and Japan are also researching maglev trains and have so far managed top speeds of 550km/h and 603km/h respectively. By contrast, China’s current high-speed trains have a top speed of between 350 and 380km/h.


The country is planning a network of superfast trains that could slash journey times on major routes.

Astronomers Think They’ve Found the Neutron Star Remnant From Supernova 1987a

Posted by in category: cosmology

In 1987, astronomers witnessed a spectacular event when they spotted a titanic supernova 168,000 light-years away in the Hydra constellation. Designated 1987A (since it was the first supernova detected that year), the explosion was one of the brightest supernova seen from Earth in more than 400 years. The last time was Kepler’s Supernova, which was visible to Earth-bound observers back in 1604 (hence the designation SN 1604).

Since then, astronomers have tried in vain to find the company object they believed to be at the heart of the nebula that resulted from the explosion. Thanks to recent observations and a follow-up study by two international teams of astronomers, new evidence has been provided that support the theory that there is a neutron star at the heart of SN 1604 – which would make it the youngest neutron star known to date.

The studies that describe their respective findings were both published in The Astrophysical Journal. The first, “High Angular Resolution ALMA Images of Dust and Molecules in the SN 1987A Ejecta,” appeared in the November 19th, 2019, issue while the second, “NS 1987A in SN 1987A,” was published in the July 30th, 2020 issue. Both studies represent the culmination of thirty years of research and waiting by astronomers.

Chernobyl Fungus Eats Nuclear Radiation Via Radiosynthesis

Posted by in categories: chemistry, nuclear energy, space

The earth’s atmosphere and magnetic field protect humans from harmful radiation. However, it is a known fact that astronauts are exposed to radiation levels that are 20-fold higher than those found on planet earth. NASA recently did an experiment on the International Space Station after realizing that a fungus growing near the Chernobyl site was thriving on nuclear radiation because of radiosynthesis. The fungus was using melanin to convert gamma radiation into chemical energy. Therefore, space scientists grew the fungus inside the ISS for a month and analyzed its ability to block radiation.

The experiment showed that the Chernobyl fungus, now identified as “Cladosporium sphaerospermum,” was able to block some of the incoming radiation. This finding has implications for future space missions. Scientists are thinking of shielding astronauts and space objects with a layer of this radiation-absorbing protective fungus. Meanwhile, let’s await further updates from NASA. Please share your thoughts with us in the comments section.

Laser beams reflected between Earth and moon boost science

Posted by in categories: physics, science, space

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced today, in collaboration with their French colleagues, that they received signal back for the first time, an encouraging result that could enhance laser experiments used to study the physics of the universe.

The NASA scientists aimed for is mounted on the Lunar Reconnaissance Orbiter (LRO), a spacecraft that has been studying the moon from its orbit since 2009. One reason engineers placed the reflector on LRO was so it could serve as a pristine target to help test the reflecting power of panels left on the moon’s surface about 50 years ago. These older reflectors are returning a , which is making it harder to use them for science.

Scientists have been using reflectors on the moon since the Apollo era to learn more about our nearest neighbor. It’s a fairly straightforward experiment: Aim a at the reflector and clock the amount of time it takes for the light to come back. Decades of making this one measurement has led to major discoveries.
