Asteroid-mining startup books its first mission, launching with SpaceX
Astroforge has received $13 million in funding after a new seed funding round led by Initialized Capital.
The Y Combinator asteroid-mining startup is based out of California, and was only founded in January 2022 with the only goal of taking "asteroid mining out of the realm of sci-fi into the realm of reality," according to AstroForge cofounder and CEO Matt Gialich.
The $13 million in funding secured will finance Astroforge's first two missions, the first of which will be a demonstration flight currently booked for a rideshare mission about a SpaceX Falcon 9 next year. Astroforge has also partnered with OrbAstro to create the first satellite for its initial demonstration flight and already has its eye on a collection of candidate asteroids to visit.

First-ever 'crypto satellite' launched into orbit by SpaceX
May 25th saw the launch of the SpaceX's Transporter-5 mission from Space Launch Complex 40 at Cape Canaveral Space Force Station (CCSFS), at 18:35 GMT.
The first stage of the Falcon 9 used in the mission returned to land intact after delivering the Crypto-1 satellite to low Earth orbit (LEO) for Cryptosat, a U.S. satellite startup. The satellite is about the size of a coffee mug, assembled with readily available parts, and was launched alongside 58 other spacecraft, including "CubeSats, microsats, non-deploying hosted payloads, and orbital transfer vehicles."
Up in orbit, the satellite is unreachable by bad actors to tamper with, but also more difficult to work with in case something goes wrong compared to something on Earth where "you just open a terminal and debug it," as noted by Cryptosat's co-founder Yan Michalevsky. Crypto-1 will enable secure cryptography for the blockchain in space and potentially facilitate the deployment of an entire space-based blockchain.

Follow Elon Musk on this tour of SpaceX's massive 'Mechazilla' tower
Tim Dodd from the YouTube account Everyday Astronaut has uploaded a continuation of his tour around Starbase with Elon Musk.
Musk accompanied Dodd on a tour throughout SpaceX's launch site in South Texas, known as Starbase. In the first part of his tour, Musk takes him through the High Bay, where Starship prototypes are assembled, and through the currently under construction MegaBay.
In the latest video, Dodd and Musk continue making their way through the facility and head up SpaceX's Orbital Launch Tower, also known as Mechazilla. The tower will support the launching and landing of the Starship spacecraft, which SpaceX plans to send to Mars, and is designed to release and catch the spacecraft with two large arms. The tower stands 469 feet (143 meters) tall, about 100 feet (30.4 meters) taller than the Statue of Liberty.

Amazing moon-shaped ice crystal formation appears on ISS window
Russian cosmonaut Sergei Korsakov has shared a remarkable photo from his view through one of the International Space Station (ISS) windows.
The picture shows ice crystals forming in a pattern very reminiscent of the moon on the inside of a window in the space station, though the real moon is nowhere to be seen in the photo. Beneath the formation is an out-of-focus Earth, peeking into the shot.
After uploading the original photo to Twitter and Telegram, Korsakov posted a follow-up photo the next day. Korsakov's accompanying caption said, "the adventures of the frosty space pattern continue!" and noted that though "the frost has melted, but the condensation pattern remains."

MIT researchers demonstrate 3D printable wood is now possible
A study on the new 3D-printed plant materials titled "Physical, mechanical, and microstructural characterization of novel, 3D-printed, tunable, lab-grown plant materials generated from Zinnia elegans cell cultures" has been published in the journal Materials Today.
Researchers from MIT have developed a method of generating "wood-like plant material" in a laboratory as a more environmentally friendly means of acquiring wood-like material than cutting down trees. Currently, about 10 million hectares of forest are lost to deforestation, an area roughly equivalent to the size of Iceland. Some scientists predict that if deforestation continues at the same rate, in 100 to 200 years, there will be no forests left in the world.
The researchers created cell cultures from leaves of the Zinnia elegans plant on liquid and gel mediums with various nutrients and two different hormones. Adjusting the levels of these hormones allowed the researchers to achieve the specific physical and mechanical characteristics of the plant cells they desired as they grew. From there, they could use a 3D printer to extrude the cell culture gel solution to create specific structures.

China is developing ways to destroy SpaceX Starlink satellites
A study published by scientists in China's peer-reviewed Modern Defense Technology journal outlines recommendations for the nation's anti-satellite capabilities.
The researchers suggest in the paper that in the event of a war, the Chinese military needs the ability to neutralize or destroy SpaceX's Starlink satellite network. The satellites could pose a potential threat to China's national security in such a scenario. Thus, the nation would need to develop an advanced surveillance system to track every Starlink satellite.
Over two thousand Starlink satellites are already in orbit, and with the ability to continue operating despite losses, Starlink is relatively resistant to complete destruction. China has already developed various anti-satellite technologies involving microwaves, lasers, nanosats launched to target bigger satellites, and cyber weapons.

Astronaut describes what it was like to see Ukraine war from space
Astronaut Matthias Maurer from the European Space Agency (ESA) returned to Earth on May 6th, 2022, after a 176-day stay aboard the International Space Station (ISS).
Speaking with German broadcaster ARD, Maurer recounted what he could see from space as the war in Ukraine unfolded after starting on February 24th, 2022, about a week after passing three months aboard the station. Maurer said the war "was clearly visible to the naked eye from space," noting "huge black columns of smoke over cities like Mariupol."
Maurer described seeing the country around the time the war began, saying, "the whole country went dark at night," but people aboard the station particularly recognized Kyiv. Within the first days of the war, they could "see lightning at night" and even explosions from "rockets hitting."

Ancient 'lost' civizilation found deep in the Amazon using lasers
A study on the civilization titled "Lidar reveals pre-Hispanic low-density urbanism in the Bolivian Amazon" has been published in the journal Nature.
Researchers have used airborne light detection and ranging (LIDAR) from a helicopter while flying over the Amazon basin to reveal evidence of previously unknown settlements. These ruins were built by a lost pre-Hispanic civilization and confirm that the region was capable of sustaining large populations of people.
Thousands of infrared LIDAR pulses per second revealed two large settlements (147 hectares and 315 hectares) and more connected by a network of roads and causeways. The settlements also had a "massive water-management infrastructure" that utilized canals and reservoirs. The new findings show the Casarabe culture from the Llanos de Mojos region of the Amazon basin extended much further than was previously known.

The smallest remote-controlled robot ever is now this tiny crab
A study on the new robots titled "Submillimeter-scale multimaterial terrestrial robots" has been published in the journal Science Robotics.
Exploratory research by engineers from Northwestern University has led to the creation of the smallest controllable robot yet, in the form of a crab smaller than the size of a flea. It can jump, bend, twist, crawl, walk, and turn without being powered by hydraulics, electricity, or other complex hardware.
The crab is controlled by applying a laser beam to its various body parts, heating them and causing them to change shape. The shape-memory alloy material used to construct the crab allows it to return to its original form once it has cooled. The robot's size allows it to cool very quickly, and using a scanning laser enables it to move in the direction the laser scans.

Elon Musk considers how to put all of humanity's DNA into storage
It has been some 20 years since scientists created the first complete reference human genome that contained approximately 3 billion DNA letters, but now some improvements are being suggested.
The first complete reference human genome has been added to over the years, with approximately two million additional variations of the code being included in the model. Now, Tesla and SpaceX CEO Elon Musk has been discussing how that model could be placed into a storage system, but on a far larger scale. Musk replied to a tweet that provided a graph on the size of a human genome in data, which stated the human genome is 3.3 Gb in size, the HIV virus is only 9.7 kb, and the largest known vertebrate genome is 130 Gb.
Antonio Regalado, the senior editor for biomedicine for MIT Technology Review, pointed out that the storage for a human genome DNA sequence is "more like 100 gigabytes" due to the extra information from sequencing. Furthermore, Musk went on to speculate that with a "lossless compression delta" and having "a few reference human genomes", one could "probably fit the DNA sequences of all humans alive today in a fairly small data storage system."

NASA discovers an underwater 'sharkano' with mutant shark species
NASA has revealed that in 2015 a group of researchers discovered two species of shark living within an active underwater volcano.
The underwater volcano called Kavachi, located in the Soloman Islands, entered into an eruptive phase in October 2021, and as a result, satellite images showed discolored water coming from the submarine volcano located 15 miles south of Vangunu island.
Notably, researchers in 2015 on an expedition discovered two species of shark living within the active crater which seemed to be able to survive in the superheated, acidic, and sulfur-rich water. Experts believe that the sharks must have mutated by some degree to be able to survive in the extreme environment.

Elon Musk showcases SpaceX's Falcon 9 rocket doing what it does best
Tesla and SpaceX CEO Elon Musk has taken to his personal Twitter account to share some images of SpaceX's Falcon 9 doing what it does best.
The SpaceX CEO posted an image of the Falcon 9 rocket that recently lifted off from Cape Canaveral Space Force Station on May 25, carrying 59 small satellites into orbit. The "rideshare" mission is titled Transporter 5, as SpaceX's rocket is carrying multiple satellites designed for various purposes from a variety of different customers.
As represented by the name, SpaceX's Transporter 5 mission marks the fifth time the company has conducted a small satellite rideshare mission, with the first rideshare mission being in January 2021, when a Falcon 9 transported 143 satellites into orbit. Musk posted an image of the Falcon 9 going supersonic as it barreled its way through Earth's atmosphere before the first stage of the rocket separated to fall back down to Earth and land in the same place it took off from.

Massive 'dragon of death' fossils uncovered, over 86 million years old
A study on the fossil specimens titled "Thanatosdrakon amaru, gen. et sp. nov., a giant azhdarchid pterosaur from the Upper Cretaceous of Argentina has been published in the journal Cretaceous Research.
Remains from the largest pterosaur species to have lived have been unearthed in Argentina in South America. Paleontologists found two specimens in the Plottier Formation, located in the Province of Mendoza. The wingspans of each specimen were 23 feet (7 meters) wide and 30 feet (9.1 meters) wide, respectively.
The specimens belong to the species Thanatosdrakon amaru and is the only species within the Thanatosdrakon genus, which belong to the Azhdarchidae family of pterosaurs. Its name derives from "Thanatos," meaning "death," "drakon" meaning "dragon", and "amaru" meaning "flying serpent." The species lived during the Cretaceous period between approximately 145.5 million and 65.5 million years ago, and these particular specimens are at least 86 million years old.

Scientists have revealed where aliens are most likely to be found
A study on binary stars and their possibility for alien life titled "Binarity of a protostar affects the evolution of the disk and planets" has been published in the journal Nature.
Researchers from the University of Copenhagen have determined that planetary systems form very differently around binary stars compared to how they do around singular stars. Almost half of all stars similar in size to our Sun exist in binary star systems, and in the search for potential alien life, looking for stars similar to our own is a good start.
The researchers used observations of the NGC 1333-IRAS2A binary star system by the ALMA (Atacama Large Millimeter/submillimeter Array) telescopes in Chile to understand more about the formation of planets around such systems. The star system exists 1,000 light years from Earth, and only a snapshot of its evolution and of its protoplanetary disc could be attained, but computer simulations have allowed the team to see how it will evolve in future and how it came be.

NASA explains this striking irregular galaxy Hubble photographed
NASA has taken to its blog to hone in on an elliptical galaxy and a surrounding unusual star-forming dwarf galaxy.
The space agency explains that the elliptical galaxy is called NGC 541, and the irregular dwarf galaxy seen as the blueish object in the above image is named the Minkowski's Object. Notably, NASA explains that elliptical galaxies are almost egg-shaped galaxies that consists of a dense group of stars that have formed after a galaxy merger. These galaxies shoot out radio jets that can't be seen by human eyes, but are detectable with NASA's high-tech instruments equipped to space telescopes such as Hubble.
Furthermore, the radio jet that has been shot out of NGC 541 has "likely" caused the star-formation that can be seen in Minkowski's Object as the extreme heat from the jet compresses the surrounding gas, heating it up - ionizing it. The ionized gas converts back to its lower-energy state, resulting in a radiation cloud. Over time this cloud then cools, beginning the slow process of starbirth. For context, Minkowski's Object holds approximately 20 million stars and is only 7.5 million years old.

A space burial company is preparing to launch 47 people's remains soon
Celestis, a space company based out of Texas, launches cremated human remains into space for space burials.
The cremated remains of 47 individuals from five countries are being launched by Celestis from Florida's Space Coast this week. The remains will be onboard a telecommunications satellite, which will orbit Earth for about a decade until it is decommissioned and eventually de-orbits and burns up on re-entry through the atmosphere.
Celestis was founded in 1994, and innovations in the space industry have allowed the company to increase its frequency of launches from about one per seven-year period to having five scheduled in the upcoming 14 months. The packages the company offers start at around $5,000.

Pasta-shaped robots with no batteries or arms are escaping mazes
Researchers have constructed a new soft robot capable of navigating through mazes without the use of batteries, motors, or computers.
The new spiral-shaped device is made from a rubber-like material that is impregnated with liquid crystals. When the device is placed on a surface, and that surface is heated to at least 131 Fahrenheit, the areas on the device that are touching the surface begin to heat up and expand, while the areas that aren't touching the surface "remain static". The result of this interaction with the heated up surface causes the device to snap in a twisting motion that moves it up to 3.8 millimeters per second.
Notably, when placed in a maze, the soft robot moves in one direction until it reaches an obstacle. Suppose the device cannot pass the obstacle after several attempts. In that case, it will switch its orientation to the opposite of what it currently was, meaning the soft robot will simply collide with all obstacles in its path until it eventually finds its correct path out of the maze. Furthermore, the researchers were able to demonstrate the soft robot with no intelligent control was able to navigate over sand, pebbles, climb slopes, and even push small aluminum cylinders.

NASA says there is 'something weird is going on' in the universe
The space agency took to its blog on May 19 to share a new study that focused on the universe's expansion rate.
The press release found on the NASA website details a study that used the Hubble Space Telescope, along with other highly advanced instruments designed to observe the universe in a variety of different ways, to accumulate a large pool of data that was boiled down to what is now considered "the most precise measure of the expansion rate for the universe" to date.
The increase in precision has come with its own problems, as researchers found a discrepancy that has left them scratching their heads. The discrepancy is between the "expansion rate as measured in the local universe compared to independent observations from right after the big bang, which predict a different expansion value." Furthermore, NASA states that previous data from Hubble indicated the universe was expanding at a rate of 72 plus or minus 8 kilometers per second per megaparsec, which is much faster than the researchers' prediction of 67.5
